Description

  The present invention relates to a sphygmomanometer that allows a user (a person to be measured) to set a pressure applied to an armband (cuff).

  In recent years, pseudohypertension due to white coat hypertension has been a problem in blood pressure measurement for hypertension treatment performed in medical institutions. As a cause of this pseudohypertension, mental instability such as tension and anxiety in front of a doctor in a hospital is considered. On the other hand, attention has been focused on blood pressure values measured in mentally stable homes. For this reason, an electronic sphygmomanometer used for measuring blood pressure in the morning and evening at the home of the user (measured person) has attracted attention.

  The problem with this type of sphygmomanometer is how to wear the armband on the arm. When the position of the air bag in the armband is not appropriate for the upper arm or when the wrapping strength is not appropriate for the upper arm, the pressure of the air bag in the armband is not correctly applied to the upper arm, and the blood pressure is high. May be. In recent years, in order to solve this, simply by inserting the arm into the cylindrical armband, the air bag for ischemia of the armband is automatically placed at the correct position of the arm, with the correct winding strength. An electronic sphygmomanometer has been developed that integrates a sphygmomanometer body and an armband that can measure blood pressure (see Patent Document 1).

  However, when the user uses the above sphygmomanometer, the armband part into which the arm is inserted is integrated with the sphygmomanometer body, so when the position of the sphygmomanometer body is away from the front of the person to be measured, The person being measured is likely to make a measurement in a leaning state. For this reason, the abdomen of the person to be measured is compressed and the abdominal pressure increases, and as a result, a phenomenon in which the blood pressure increases may be seen. This increase in blood pressure is pointed out as the occurrence of new pseudohypertension.

  Therefore, it has been proposed that the armband portion is formed separately from the main body of the sphygmomanometer, and the armband portion has a rigid case, and an air bag for ischemia is disposed in this case. ing. As a result, when the person to be measured (user) measures blood pressure in the sitting position, the arm band part can be separated from the blood pressure monitor main body, so that the convenience of measurement can be reduced simply by inserting the upper arm into the arm band part. Therefore, even if the place where the blood pressure monitor main body is installed is away from the person to be measured, it is possible for the measurer to correctly measure blood pressure in a state where the abdominal pressure is not applied when the back is stretched.

However, in the sphygmomanometer used at home described above, when the pressure value of the armband part has been set in advance by default, an appropriate armband is suitable for a person who actually measures blood pressure. It cannot be said that the optimum pressure is applied to the part.
Therefore, for each blood pressure measurement, pressurizing the armband part while detecting insufficient pressurization of the armband part, the pressurization speed of the armband part becomes slow, and it takes time to pressurize to the optimum pressure, The burden on the person being measured increases.

  Accordingly, an object of the present invention is to provide a sphygmomanometer that can accurately measure blood pressure without burdens such as each measurement subject spending a long measurement time for measurement.

  A sphygmomanometer according to the present invention includes an armband portion to be worn on the upper arm of a person to be measured, a pressurizing unit that pressurizes the inside of the armband portion, a control unit, and a pressure sensor that detects a pressure in the armband portion, A sphygmomanometer comprising: a pressure reducing means for reducing the pressure in the armband portion, and receiving the pressure signal from the pressure sensor and controlling the pressure applying means and the pressure reducing means by the control unit to measure blood pressure. A setting unit for selecting the measurement subject to be subjected to blood pressure measurement to the control unit, and setting a pressurization value of the armband portion suitable for the selected measurement subject; The control unit that performs blood pressure measurement with respect to the measured person selected by a setting unit using a pressurization value of the armband part suitable for the selected measured person. . According to the above configuration, each measured person accurately measures blood pressure without feeling a burden by individually registering the pressure values of the armband portions suitable for each measured person at the time of the first measurement. be able to. That is, the person to be measured for blood pressure measurement is selected, and the pressure value of the armband part suitable for the selected person to be measured is individually registered, and is suitable for the selected person to be measured. Since the blood pressure can be measured by the pressurization value of the armband portion, each person to be measured can accurately measure the blood pressure without feeling a burden.

  Preferably, the person to be measured that is connected to the control unit and has already been registered by the setting unit is stored in advance as a registered person, and the armband part suitable for the person to be measured who is the registered person is added. It has the memory | storage part which memorize | stored the pressure value previously, It is characterized by the above-mentioned. According to the above configuration, the person to be measured as a registered person can be stored in the storage unit in advance and pressurized by the pressure value of the armband part suitable for the person to be measured. However, blood pressure can be accurately measured without a burden.

Preferably, the storage portion stores in advance pressure values of the armband portions in different time zones for the measured person who is the same registered person. Even when the blood pressure of the same subject is always measured, the problem is that the systolic blood pressure in the morning is often different from the systolic blood pressure in the evening.
In order to solve this, according to the above-described configuration, the measured person who is the same registered person can accurately measure the blood pressure without feeling a burden even when the measured blood pressure is in a different time zone. Can do.

Preferably, the armband portion is separate from the sphygmomanometer main body, and the armband portion is attached to the upper arm, and a blood-filling air bag for blocking the upper arm when attached to the upper arm. The microphone for detecting Korotkoff sound is housed, and the air bag for ischemia is connected to the pressurizing means and the decompressing means in the sphygmomanometer body.
According to the above configuration, the armband part and the sphygmomanometer body are separate from each other, so that the convenience of measurable by simply inserting the upper arm into the armband part is not impaired, and the location of the sphygmomanometer body is measured Even if it is away from the person, the blood pressure can be measured in a state where the abdominal pressure is not applied when the measurer is correctly stretched.

  The present invention allows each subject to accurately measure blood pressure without feeling a burden by individually registering the pressure value of the armband suitable for each subject to be measured at the time of the first measurement. A sphygmomanometer that can be provided can be provided.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.
FIG. 1 is a perspective view showing the entire embodiment of the blood pressure monitor of the present invention. FIG. 2A is a perspective view of the sphygmomanometer body of the sphygmomanometer shown in FIG. 1 as viewed from the left rear side. FIG. 2B is a perspective view of the sphygmomanometer body of the sphygmomanometer shown in FIG. 1 as viewed from the right rear side.

  The sphygmomanometer 1 shown in FIG. 1 is also referred to as an electronic sphygmomanometer. In the sphygmomanometer 1, the armband portion 2 and the sphygmomanometer body 10 are separate from each other. 1 and the armband part 2 shown in FIG. 1 are used separately from the blood pressure monitor main body 10 shown in FIG. Unlike the integrated sphygmomanometer in which the armband portion and the main body portion are integrated, the sphygmomanometer 1 has a place where the sphygmomanometer main body 10 is placed forward from the subject when the subject measures in the sitting position. Even when the person to be measured wears the armband portion 2 on the upper arm T, blood pressure can be measured in a state where the back is stretched and no abdominal pressure is applied. That is, the sphygmomanometer 1 does not impair the convenience of being able to measure by simply inserting the upper arm T into the armband portion 2, and even if the place where the sphygmomanometer main body 10 is installed is away from the subject, the measurer The blood pressure can be measured in a state where the abdominal pressure is not applied when the back is stretched.

  The armband part 2 shown in FIG. 1 is also called a cuff, and the armband part 2 has a constant (predetermined) outer peripheral length, and is a soft cylinder body that is made of a foldable and soft material. Yes, it has two openings 11P and 11R. When the arm band 2 is attached to the upper arm T of the measurement subject, the opening 11P is positioned on the finger side, and the opening 11R on the opposite side is positioned on the shoulder side. The inner diameter of the opening 11R is larger than the inner diameter of the opening 11P. The finger of the person to be measured is inserted from the opening 11R side to the opening 11P, so that the armband part 2 is held on the upper arm T above the elbow of the person to be measured to measure blood pressure. Yes.

As shown in FIG. 1 and FIG. 2, the armband portion 2 is preferably used for detecting the K sound (Korotkoff sound) signal for detecting the K sound (Korotkoff sound) signal and the air bag 14 for blocking the upper arm T. Built-in microphone 50.
The air bag 14 for ischemia pressurizes the artery of the upper arm T and supplies blood by supplying air through the air tube 4 from the blood pressure monitor main body 10 side. The air capacity of the air bag 14 is such that the upper arm T of the person to be measured can be pressurized with a necessary pressure. As shown in FIG. 1, the two K sound detection microphones 50 are arranged so as to face each other when the armband portion 2 is attached to the upper arm T.

The two microphones 50 for detecting the K sound can employ, for example, preferably a small disc capacitor microphone in order to detect the K sound. This K sound increases the internal pressure of the air bag 14 for the ischemia of the armband 2 to the maximum blood pressure or higher to temporarily close the blood vessel, then gradually decreases the internal pressure to the internal pressure becomes the maximum blood pressure or lower and the blood vessel begins to open. Is a sound signal that can be detected until the internal pressure falls below the minimum blood pressure and the occlusion of the blood vessel disappears.
As shown in FIG. 1, the armband portion 2 and the sphygmomanometer body 10 are connected via an air tube 4, an electrical wiring 5, and a plug 6. The air tube 4 is preferably a flexible elastomer tube. The air tube 4 is used for supplying and exhausting air to and from the air bag 14 for ischemia of the armband portion 2. The electrical wiring 5 is electrically connected to the two microphones 50 described above. The plug 6 is used for detachably connecting the air tube 4 and the electrical wiring 5 to the blood pressure monitor main body 10 side.

First, an example of the structure of the armband portion 2 will be described with reference to FIGS. 1 and 3.
3A is a cross-sectional view showing an example of the internal structure of the armband portion 2, FIG. 3B is a front view showing a state in which the armband portion 2 is folded, and FIG. It is a perspective view which shows the state which folded the armband part 2. FIG.
As shown in FIGS. 1 and 3, the armband portion 2 is a cylindrical member that is not cut along the outer circumferential direction, and has an outer periphery of a predetermined (constant) length. The upper arm T of the person to be measured can be passed through the part 2. As shown in FIG. 3 (B) and FIG. 3 (C), the armband portion 2 has the flexibility that the person to be measured can easily fold, and as shown in FIG. 1 and FIG. 3 (A), For example, it has an outer cloth 16, an inner cloth 17, an air bag 14 for blocking the upper arm T, and two K sound detecting microphones 50 for detecting a K sound signal.

The inner side surface of the outer cloth 16 and the outer side surface of the inner cloth 17 shown in FIG. 3A wrap the air bag 14 for ischemia and two microphones 50 for detecting K sound, and the outer cloth 16 and the inner cloth 17 are The end of the outer cloth 16 and the end of the inner cloth 17 are joined together by sewing, for example, to create a donut-shaped space in which the air bag 14 for ischemia and the two microphones 50 for detecting K sound can be stored. doing.
Note that the two K sound detection microphones 50 are preferably positioned closer to the opening 11P side than the intermediate position in the longitudinal direction (axial direction) of the armband portion 2 (not the shoulder side but the position closer to the fingers). ) Is good to place. In this way, one of the two K sound detection microphones 50 can be applied to the portion corresponding to the artery of the upper arm T.

The outer cloth 16 shown in FIG. 3 (A) is a cylindrical body that covers the outer surface of the air bag 14 for ischemia, and is formed of a non-stretchable material in the circumferential direction and the longitudinal direction. It is a fabric member that has very low or no properties. Thereby, the outer cloth 16 can prevent the air bag 14 from being inflated in the radial direction of the armband portion 2 when air is supplied into the air bag 14. The bag 14 swells toward the upper arm T, which is the inner side in the radial direction.
For this reason, the pressure of the air bag 14 for ischemia can be applied to the upper arm T without escaping to the outside of the armband portion 2, and the two microphones 50 for detecting K sound can be applied to the skin surface of the upper arm T (measured object). Since it can be pressed against the surface) side, accurate blood pressure measurement can be performed.

  The outer fabric 16 shown in FIG. 3 (A) can employ, for example, a fabric (201BE) that is difficult to stretch, and the tensile strength is a value measured by the JIS L1096-A method. Is 810 N / in to 850 N / in. Furthermore, it is preferable that the length is 1430 N / in to 1460 N / in and the width is 810 N / in to 850 N / in. If both the length and the width are smaller than this numerical range, the suppression of the outward expansion of the air bag 14 is weakened, and if it is larger than this numerical range, the insertion of the upper arm T may be affected. As the outer cloth 16, for example, when a 100% polyester fabric is used, the length is 1445 N / in and the width is 827 N / in.

  The inner cloth 17 shown in FIG. 3 (A) is a cylindrical body that covers the inner surface of the air bag 14 for ischemia and the two microphones 50 for detecting K-sounds, is deformable, has elasticity, and measures the upper arm T. It is the contact cloth part which contacts the surface. The inner cloth 17 may be a stretchable cloth member that is elastic and has elasticity, for example, and the tensile strength is 94.9 N / in in length as measured by the JIS L1096-A method. The width is 150.7 N / in. Tensile elongation is 517% in length and 400% in width as measured by JIS L1096-A method. The inner fabric is, for example, a fabric made of 80% nylon and 20% polyurethane. The inner cloth 17 is made of a stretchable material so that the air bag 14 for ischemia can be expanded toward the measurement surface of the upper arm T, and the armband portion 2 is inserted from the hand of the measurement subject. Since the upper arm T of the elbow needs to be slid and mounted, a smooth material such as a jersey material is used.

  As shown in FIGS. 3A to 3C, the opening closing member 30 is on the opening 11P side inside the armband portion 2, and the air tube 4 and the electrical wiring 5 are led out (connected). Is provided on the side. The opening closing member 30 can use, for example, a removable surface fastener, and has a male member 31 and a female member 32 of the surface fastener. The male member 31 and the female member 32 are fixed at positions facing each other inside the armband portion 2, and the male member 31 and the female member 32 are attached and detached as shown in FIGS. 3 (B) and 3 (C). By connecting in a possible manner, only the opening 11P side of the armband portion 2 can be closed, and the opening 11R can be kept open.

  Thereby, by providing the opening closing member 30 for the armband part 2, when the person to be measured tries to measure blood pressure through the hand with respect to the armband part 2, from the closed opening part 11P side. Without passing the hand, it is possible to pass the hand without getting lost from the open opening 11R side. For this reason, it can prevent that a to-be-measured person inserts a hand back into the armband part 2 accidentally from the opening part 11P side. If the measurement subject reversely inserts the armband part 2 from the opening 11P side, the two K sound detection microphones 50 do not properly hit the artery of the upper arm T, and blood pressure measurement can be performed accurately. become unable. Further, by providing the opening closing member 30 with respect to the armband portion 2, it can be easily folded when the armband portion 2 is not used.

  As shown in FIGS. 1 and 3, the armband portion 2 has a tag 33 that is a member for visually confirming a direction. The tag 33 is on the opening 11R side, and is fixed to the outer fabric 16 by using, for example, an adhesive or by sewing. The tag 33 is provided so as to protrude along the V direction from the end of the armband portion 2 on the opening 11R side, and can be made of, for example, a cloth member or a plastic member. As shown in FIG. 3A, when the person to be measured inserts his left arm into the armband portion 2 and measures blood pressure, for example, the user grasps the tag 33 with the finger F of the right arm and holds the armband portion 2 in the V direction. Can be moved to. The tag 33 can preferably be labeled with a “shoulder side” display 33S. As a result, the measurement subject can easily attach the armband portion 2 to the upper arm T simply by grasping the tag 33 and moving in the V direction, and the attachment direction of the armband portion 2 is clear. Therefore, it is possible to pass the hand without hesitation from the opening 11R side. For this reason, it can prevent that a to-be-measured person inserts a hand back into the armband part 2 accidentally from the opening part 11P side.

Next, a structural example of the blood pressure monitor main body 10 will be described.
As shown in FIGS. 1 and 2, the sphygmomanometer body 10 includes a housing part 60, a display surface part 61, and a holding part 62 for the armband part 2.

As shown in FIG. 2, the arm belt holding portion 62 is detachably attached to the back side of the housing portion 60. FIG. 4 shows a state where the folded armband portion 2 is detachably housed on the back surface 66 side of the housing portion 60 using the holding portion 62.
As shown in FIG. 4, the holding part 62 of the armband part has a holding surface 62A and a leg part 62B. An insertion port 67 is formed on the lower side of the housing unit 60. The distal end portion 62C of the leg portion 62B is inserted into the insertion port 67, whereby the arm belt portion holding portion 62 can be detachably attached to the back surface 66 side of the housing portion 60. Between the holding surface 62A and the back surface 66 of the housing portion 60, the folded armband portion 2 can be detachably accommodated. Thereby, when a to-be-measured person does not use the armband part 2, the folded armband part 2 can be accommodated easily and reliably. When the person to be measured does not measure blood pressure, the armband part 2 is on the back of the housing part 60, so that the person to be measured is not disturbed by the armband part 2, and the display contents of the display unit 63, such as time and Since the room temperature and the like can be visually confirmed, it can be easily confirmed whether or not the temperature is suitable for blood pressure measurement (environmental temperature). Furthermore, the appearance of the sphygmomanometer 1 can be improved. For this reason, the sphygmomanometer body 10 can be displayed in a living room or the like as a clock when not in use.

As shown in FIG. 2A, a plug provided with an O-ring (not shown) is provided at a lower position of a side surface portion 68 (a left side surface portion facing the front surface of the housing portion 60) of the housing portion 60. A mouth 73 is formed. The plug 6 can be detachably attached to the insertion port 73. In accordance with the shape of the plug 6, the width d1 of the upper portion 73A of the insertion port 73 is set larger than the width d2 of the rounded lower portion 73B. Inside the insertion port 73, insertion holes 73G and 73H are provided.
On the other hand, the plug 6 is made of, for example, plastic, and includes a main body 6A, connection cylinder portions 6B and 6C, and a connection guide portion 6F. The connecting cylinder portions 6B and 6C are formed so as to protrude in parallel from the surface of the connecting guide portion 6F. These connecting cylinder portions 6B and 6C are removably inserted into the insertion holes 73G and 73H of the insertion port 73, respectively. The connecting cylinder portion 6B is an electric terminal portion connected to the electric wiring 5, and the connecting cylinder portion 6C is an air supply terminal connected to the air tube 4.

The upper portion 6H of the connection guide portion 6F of the plug 6 shown in FIG. 2A is inserted while being guided by the upper portion 73A of the insertion port 73 shown in FIG. The lower part 6G is guided and inserted into the lower part 73B of the insertion port 73. Thereby, the plug 6 is prevented from being mounted upside down with respect to the insertion port 73.
The arm strap 2 connected to the plug 6 is easily available in a plurality of sizes, for example, three sizes of large, medium and small, and the most suitable one is selected according to the size of the upper arm of the user. It can be done. Further, the plug 6 is provided on the side surface of the sphygmomanometer main body 10 so that even if the drive pump 110 shown in FIG. 5 runs out of control and the armband portion 2 is abnormally pressurized. In addition, abnormal pressure on the armband portion 2 can be avoided very easily by the person to be measured pulling out the plug 6 without providing a complicated electronic circuit or an abnormal switch.
Returning to FIG. 2B, the side surface 69 of the housing 60 is provided with a speaker 85 and a connection hole 86 for connecting an AC adapter. By connecting a connection jack 87A of an AC adapter 87 to the connection hole 86, the sphygmomanometer body 10 can be supplied with power from a commercial power source.

FIG. 5 is a block diagram of the sphygmomanometer 1 shown in FIG.

It is connected to the valve 111 and the exhaust valve 112. Elements such as the control unit 120 are mounted on the circuit board 100. The control unit 120 includes a CPU such as a microcomputer, a control program for the entire apparatus executed by the CPU, a ROM that stores various data, a RAM that temporarily stores measurement data and various data as a work area, and the like. Processing and judgment in
The two microphones 50 that detect the K sound signal are electrically connected to the filter 700 and the OSC amplifier 162 through the electric wiring 5. The pressure detection unit (pressure sensor) 140 detects the pressure in the armband unit 2. As shown in FIG. 5, the two microphones 50 can be accurately detected by providing the two microphones 50 so as to be opposed to each other in the circumferential direction when the armband portion 2 is attached to the upper arm. The number may be one.

The two drive pumps 110 shown in FIG. 5 are pressurizing means that pressurize the upper arm in the armband 2 by supplying air to the air bag 14 for ischemia in the armband 2. As described above, the two drive pumps 110 are used when the armband portion 2 is large, when the two drive pumps are driven, and when the armband portion 2 is small, the one drive pump is driven. This is because air can be supplied to the air bag 14 for ischemia.
The control valve 111 and the exhaust valve 112 are decompression means for decompressing the upper arm that has been evacuated and pressurized by removing air from the air bag 14 in the armband portion 2. The drive unit 150 drives and controls the two drive pumps 110 according to a command from the control unit 120. The drive unit 151 controls the control valve 111 and the exhaust valve 112 according to a command from the control unit 120.

In FIG. 5, the control unit 120 gives a command to the display unit 63, for example, notification contents such as temperature display, time display, systolic blood pressure, diastolic blood pressure, and alarm as shown in FIG. Can be displayed. An audio memory 153 and a data memory 154 are connected to the control unit 120.
The voice memory 153 stores in advance voice guidance contents to be given to the measurement subject when measuring the blood pressure monitor.
The control unit 120 can notify the measurement subject of the voice guidance content in the voice memory 153 through the speaker 85 during blood pressure measurement. For example, when the measurement of the minimum blood pressure value and the maximum blood pressure value is started, the speaker 85 can play a voice guidance that “the minimum blood pressure value and the maximum blood pressure value are being measured”.
The data memory 154 stores in advance a program for performing a series of operations necessary for blood pressure measurement and a registered user display area 63M as shown in FIG. 8A. The blood pressure measurement operation is performed according to

In FIG. 5, the start / stop switch 88, the function selection key 400 and the up / down key 450 of the setting unit 380 are electrically connected to the control unit 120. The speaker 85 is electrically connected to the control unit 120 via the filter 164. The power control unit 160 is electrically connected to the battery 93, and is electrically connected to the AC adapter 87 through the connection connector 86, and supplies a predetermined DC voltage to the control unit 120. The control unit 120 has a clock 500 that generates a reference time.
The power control unit 160, the K sound amplifier 161, and the OSC amplifier 162 are electrically connected to the control unit 120. The K sound amplifier 161 amplifies the K sound detected by the two microphones 50 and supplies the amplified K sound to the control unit 120. A noise removal filter 700 is electrically connected between the two microphones 50 and the K sound amplifier 161. The OSC amplifier 162 amplifies the pulse wave signal detected by the microphone 50 and supplies it to the control unit 120. Thereby, the control part 120 can recognize K sound and can recognize a pulse wave. The noise removal filter 700 is a filter for removing music noise other than the K sound from the sound that has entered the microphone 50, and other than the frequency range of the K sound input to the microphone 50. The frequency range is removed as noise, and the frequency range of the K sound is passed to the K sound amplifier 161 side.

FIG. 6 shows an example of an operation in which a person to be measured measures blood pressure by supplying air to the air bag 14 for ischemia and pressurizing the upper arm T through the upper arm T to the armband portion 2 as shown in FIG. It is a graph. The vertical axis represents pressure, and the horizontal axis represents time.
In FIG. 6, the control unit 120 shown in FIG. 5 operates the control valve 111 and the two drive pumps 110 to supply air to the hemostasis air bag 14 and pressurize the upper arm to the time point t1, and then the control valve 111. Is activated, and the air pressure in the air bag 14 for ischemia is reduced to time t2 so that the inclination becomes constant. The controller 120 detects the systolic blood pressure and the systolic blood pressure during the decompression, and then the controller 120 operates the exhaust valve 112 to evacuate the air in the air bag 14 for ischemia.

FIG. 7 is a flowchart showing an example of the operation of using the sphygmomanometer. FIG. 8A is a measurement subject table TB showing an example of the pressure value of the armband corresponding to the systolic blood pressure value applied to each of the plurality of measurement subjects, and FIG. It is a block diagram which shows the clock 500 etc. of the control part 120. FIG. The measured person table TB shown in FIG. 8A is registered in the data memory 154 as an example of the storage unit shown in FIG.
In the person-to-be-measured table TB of FIG. 8A, for the sake of simplicity, as an example, two persons to be measured PA and a person to be measured PB as a plurality of persons to be measured for blood pressure are included. , As a registered person.

In the measurement subject table TB, the arm band pressure value VPA corresponding to the morning systolic blood pressure is individually set for the measurement subject PA, and the morning systolic blood pressure is individually set for the measurement subject PB. A pressurizing value VPB of the armband portion corresponding to is set. Further, in the measurement subject table TB, the pressure value WPA of the armband corresponding to the systolic blood pressure in the evening is individually set for the measurement subject PA, and the evening contraction is individually set for the measurement subject PB. A pressurization value WPB of the armband corresponding to the period blood pressure is set.
As described above, since the two persons to be measured PA and the person to be measured PB have already been determined as registered persons, the addition of the morning and evening armband part 2 suitable for each of the registered persons to be measured PA and PB. The pressure values can be individually registered in the measured person table TB in the data memory 154 shown in FIG.

As illustrated in the measurement subject table TB in FIG. 8A, the morning time zone for measuring blood pressure is, for example, from 6:00 am to 9:00 am, and the evening time zone for measuring blood pressure. As, for example, it is set from 4 pm to 7 pm. The time can be set by the measurement subject according to the reference time generated by the clock 500 of the control unit 120.
The setting and changing of the pressurization value of the armband part 2 suitable for each person to be measured PA and PB and the setting and changing of the morning time zone and the evening time zone are shown in FIG. 5 and FIG. Using the function selection key 400 and the up / down key 450 of 380, the data can be preset in the data memory 154 shown in FIG. In other words, the setting unit 380 selects a person to be measured for blood pressure measurement, sets a pressure value of the armband part suitable for the selected person to be measured, and selects an arbitrary morning time zone or evening time. Used to set the time zone.

The function selection key 400 and the up / down key 450 shown in FIG. 2 are arranged next to the start / stop switch 88 of the sphygmomanometer main body 10.
A function selection key 400 shown in FIG. 2 is displayed every time the measurement subject presses with a finger, in response to a command from the control unit 120 shown in FIG. 5, as shown in FIG. A display mode for displaying the registered person display area 63M of a plurality of measured persons who are registered persons on the display unit 63, a pressurization value setting mode for setting the pressurization value of the armband unit 2, and the morning A measurement time setting mode or the like in which the time of the time zone or evening time zone can be arbitrarily set by the measurement subject can be arbitrarily selected. The display unit 63 shown in FIG. 1 does not display the display content in the pressurization value setting mode and the display content in the measurement time setting mode, but the display unit 63 does not control in the pressurization value setting mode. By the command of the unit 120, the pressurization values VPA and VPB of the armband corresponding to the morning systolic blood pressure and the pressurization values WPA and WPB of the armband corresponding to the systolic blood pressure of the evening can be displayed. Similarly, in the measurement time setting mode, the display unit 63 can display a morning time zone and an evening time zone according to a command from the control unit 120.

As shown in FIG. 2, the up / down key 450 has an up key 451 and a down key 452. In each display mode, pressurization value setting mode, and measurement time setting mode described above, Press to increase or decrease each value.
The measured person presses the function selection key 400 in FIG. 8B to select the display mode, and the registered person display area 63M of a plurality of measured persons is displayed on the display unit 63 as shown in FIG. In the registered user display area 63M, for example, a plurality of persons to be measured PA and PB who are registered persons are displayed. When the subject operates the up key 451 or the down key 452, any one of the plurality of subjects PA and PB who are already registered persons displayed in the registered person display area 63M is selected. A person to be measured can be selected.

As a result, as shown in FIG. 8A, for example, when the blood pressure measurement time is in the morning time zone and the person to be measured PA is selected as the registered person, the control unit 120 has the morning of the person to be measured PA in the morning. The arm band pressure value VPA corresponding to the systolic blood pressure can be set. Further, for example, if the blood pressure measurement time is in the morning time zone and the person to be measured PB is selected as a registered person, the control unit 120 has an arm band corresponding to the morning systolic blood pressure of the person to be measured PB. Pressure value VPB can be set.
For example, if the blood pressure measurement time is the evening time zone and the subject PA is selected as a registered person, the control unit 120 adds an arm band corresponding to the systolic blood pressure in the evening of the subject PA. Pressure value WPA can be set. Further, for example, if the blood pressure measurement time is the evening time zone, and the person to be measured PB is selected as the registered person, the control unit 120 will have the arm band corresponding to the systolic blood pressure in the evening of the person to be measured PB. The pressurization value WPB can be set.
Further, the measurement subject presses the function selection key 400 in FIG. 8B to select the measurement time setting mode, and presses the up key 451 and the down key 452, so that the blood pressure measurement time zone in the morning and the blood pressure in the evening are preliminarily set. The time of the measurement time zone can be set. Therefore, the person to be measured sets or changes the numerical values of the preferred morning time zone and evening time zone as necessary, and the subject person table TB in the data memory 154 shown in FIG. Can be memorized.

Next, an example of use operation of the sphygmomanometer 1 having the above-described configuration will be described with reference to FIGS.
In the following description, the two measured persons PA and the measured person PB shown in the measured person table TB of FIG. 8A are registered persons, but the measured person PC shown in the measured person table TB is A case where a new measured person (user) is not a registered person will be described as an example.
In addition, in the first measurement after purchasing the sphygmomanometer 1, there is no registered person, and when taking data in the first measurement for each person to be measured, the following new measured person for each measurer The measurement can be performed and the data can be registered.
Referring to FIG. 7, in step S <b> 1 shown in FIG. 7, when the person to be measured is a new person to be measured PC shown in FIG. 8A, in step S <b> 2, the new person to be measured PC is A function selection key 400 shown in FIG. 5 is pressed to select a pressurization value setting mode, and an up key 451 and a down key 452 are pressed. Thereby, the new measurement subject PC manually sets the pressurization value VPC corresponding to the morning systolic blood pressure individually and sets the pressurization value WPC corresponding to the evening systolic blood pressure individually. Can do.

Thus, in step S3, the new measurement subject PC adds the arm band pressurization value VPC corresponding to the morning systolic blood pressure set manually and the arm band corresponding to the evening systolic blood pressure. The pressure value WPC can be newly registered in the measured person table TB in the data memory 154 shown in FIG.
In step S4 of FIG. 7, the control unit 120 shown in FIG. 5 operates the control valve 111 and the two drive pumps 110 to supply air to the air bag 14 for ischemia until the upper arm reaches the time point t1 in FIG. Pressurize automatically.
In step S4-1, pressurization is stopped, and then in step S5 of FIG. 7, the control valve 111 is operated to reduce the air pressure in the ischemic bladder 14 so that the inclination is constant, and the microphone 50 Detects the K sound or pulse wave, and determines the maximum blood pressure (systolic blood pressure) value based on the corresponding air pressure in the air bag 14 for ischemia.

In step S6 in FIG. 7, the control valve 111 in FIG. 5 is further operated to continue the pressure reduction of the air in the air bag 14, and in step S7, the control unit 120 in FIG. By detecting the pulse wave, the minimum blood pressure (diastolic blood pressure) value is determined based on the air pressure in the corresponding air bag 14 for ischemia. In step S8, as shown in FIG. 1, the control unit 120 in FIG. 5 displays the maximum blood pressure value determined in the display unit 63 and the numerical values such as the minimum blood pressure value and the pulse, and in step S9. Ends the blood pressure measurement operation. When the upper arm moves at the time of measurement (so-called body movement), the subject can be notified of the presence or absence of body movement by blinking when displaying the maximum blood pressure value and the minimum blood pressure value.
When the person to be measured measures blood pressure, the K sound or pulse wave can be detected using the two microphones 50 built in the armband part 2, and the sphygmomanometer 1 can reliably detect the K sound. Blood pressure can be measured accurately. As described above, the K sound is generated by raising the internal pressure of the air bag 14 for the ischemia of the armband portion 2 to the maximum blood pressure value and once closing the blood vessel, and then gradually reducing the internal pressure so that the internal pressure is less than the maximum blood pressure value. The sound signal is generated when the blood vessel begins to open, and can be detected until the internal pressure becomes equal to or lower than the minimum blood pressure value and the occlusion of the blood vessel disappears.

On the other hand, when returning to step S1 in FIG. 7, the person to be measured for blood pressure measurement is not a new person to be measured PC but the person to be measured PA and the person to be measured shown in FIG. 8A. If it is any of PB, the process proceeds to step S10.
In step S10, the control unit 120 in FIG. 5 determines whether the registered person PA or the person PB who has already registered presses the start / stop switch 88 shown in FIG. 2 for a long time. When the control unit 120 determines that the registered person PA or the measured person PB has long pressed the start / stop switch 88, the control unit 120 determines whether the registered person is a measured person in step S14. It is determined that the PA or the person to be measured PB cancels the automatic pressurization value setting operation of the armband unit 2 and manually sets the pressurization value of the armband unit 2, and the process proceeds to step S <b> 5. Steps S5 to S9 are executed.

Otherwise, in step S10 in FIG. 7, if the registered person PA or the person PB who has already been registered does not hold down the start / stop switch 88 shown in FIG. 2, the process proceeds to step S11.
In step S11, the control unit 120 determines which one of the person to be measured PA and the person to be measured PB is actually designated as a specific registered person. In this case, if neither the subject PA or the subject PB is specified, the process proceeds to step S9 and the blood pressure measurement operation is terminated.
In step S11, when either the subject PA or the subject PB is actually designated as a specific registered person, in step S12 in FIG. Designate and select one of the person to be measured PB. For example, when the person to be measured PB is selected in the registered person display area 63M in FIG. 2, the morning of the person to be measured PB in FIG. 8A is matched with the time when the person to be measured PB is selected. Either the pressurization value VPB of the armband corresponding to the systolic blood pressure or the pressurization value WPB of the armband corresponding to the systolic blood pressure in the evening of the measurement subject PB is shown in FIG. It can be automatically selected according to the current time that the clock 500 is timing.

  For example, if the time when the person to be measured PB intends to measure blood pressure is the measurement time zone in the morning, the pressure value VPB of the armband portion corresponding to the morning systolic blood pressure is automatically selected. In step S13, the control unit 120 of FIG. 5 pressurizes the pressurization value of the armband 2 to the pressurization value VPB, and the control valve 111 is activated to keep the air pressure in the ischemic bladder 14 constant. The microphone 50 detects the K sound or the pulse wave level during the pressure reduction.

In step S12 and step S13 described above, the person to be measured PB is selected as an example of the registered person, and the person to be measured PB adds, for example, an arm band corresponding to the morning systolic blood pressure of the person to be measured PB. The case where the pressure value VPB is selected has been described. However, if the time when the person to be measured PB intends to measure blood pressure is the measurement time zone in the evening, the pressure value WPB of the armband corresponding to the systolic blood pressure in the evening is automatically selected. For this reason, blood pressure can be measured in the same manner even when the person to be measured PB selects the pressure value WPB of the armband corresponding to the systolic blood pressure in the evening of the person to be measured PB, for example.
Further, in steps S12 and S13 described above, the measurement subject PA is selected as an example of the registered person, and the measurement subject PA is, for example, the armband corresponding to the morning systolic blood pressure of the measurement subject PA. The pressurization value VPA may be selected. As an example of a registered person, the person to be measured PA may be selected, and the person to be measured PA may select, for example, the pressure value WPA of the armband corresponding to the systolic blood pressure in the evening of the person to be measured PA. .

As described above, in the sphygmomanometer 1 according to the embodiment of the present invention, every time the measurement subject performs blood pressure measurement, the sphygmomanometer 1 does not search again for the pressurization value of the armband part suitable for the measurement subject. If the person to be measured is a registered person, this person to be measured is determined and can be specified in advance, so that even if there are a plurality of persons to be measured, the pressure value of the armband part suitable for each of the plurality of persons to be measured, It can be registered in the data memory 154 in advance at the time of the first measurement.
In the next measurement, if the person to be measured is not a new person to be measured but a registered person, the control unit 120 sets the pressure value of the armband part suitable for the person to be measured who is the registered person. Reading from the data memory 154, the control unit 120 pressurizes the armband unit 2 in a so-called “individual measurement mode” so that each person can measure blood pressure quickly and accurately without a burden. Become.

  As shown in FIG. 8A, even in the same subject, for example, in the morning and evening, the pressure value of the armband corresponding to the morning systolic blood pressure and the systolic blood pressure in the evening Corresponding armband pressure values are different. The measurement subject can arbitrarily set the morning blood pressure measurement time zone range and the evening blood pressure measurement time zone range based on the time measured by the clock 500 built in the control unit 120. Even for the same person to be measured, the pressurization value of the armband portion 2 can be selected according to the time zone to be measured. That is, the control unit 120 selects the pressure value of the armband part 2 from the condition of the person who wants to measure blood pressure and the blood pressure measurement time, reads it from the data memory 154, and quickly and accurately in the designated mode. Blood pressure can be measured.

In addition, in step S5 of FIG. 7, the control unit 120 of FIG. 5 not only detects the blood pressure value by detecting the K sound, but also detects by using a pulse wave (preferably a pressure pulse wave), In the case of detecting a blood pressure value, the process can proceed to step S5-1 indicated by a broken line. In this case, one small air bag for detecting a pulse wave is provided instead of the two microphones 50, or the pulse wave from the air bag 14 for isolating blood is discriminated.
In step S5-1, it is determined whether the control unit 120 has detected a pulse wave with the pressurization value determined in the pulse wave detection result. If the pressurization value is other than the determined pressurization value, the arm stored in step S3 is determined. The pressure value of the belt portion can be corrected and stored again in the measured person table TB in the data memory 154 shown in FIG. 8A as the first pressed value of the measured person PC. Thereafter, steps S6 to S9 are executed.

  The sphygmomanometer 1 according to the embodiment of the present invention registers each armband pressure value suitable for each of the plurality of measured persons individually at the time of the first measurement, so that each measured person can accurately and without burden. Blood pressure can be measured. That is, the person to be measured for blood pressure measurement is selected, and the pressure value of the armband part suitable for the selected person to be measured is individually registered, and is suitable for the selected person to be measured. Since the blood pressure can be measured by the pressurization value of the armband portion, each person to be measured can accurately measure the blood pressure without feeling a burden.

By the way, this invention is not limited to the said embodiment, A various modified example is employable. Each embodiment of the present invention can be arbitrarily combined.
The two persons to be measured PA and the person to be measured PB shown in FIG. 8A are registered persons. However, the present invention is not limited to this. Of course, three or more measured persons may be registered as registered persons. .
The armband portion 2 shown in FIGS. 1 and 3 has a tag 33. On the other hand, the armband part 2 shown in FIG. 9 has the tag 233 of another shape. The tag 233 is fixed to the outer fabric 16 along the longitudinal direction of the armband portion 2 from the opening 11R side to the opening 11P. The tag 233 has a knob portion 233A provided so as to protrude from the opening 11R of the armband portion 2 along the V direction, and a finger insertion portion 233B for passing the finger F as shown in FIG. 9B. doing. The tag 233 may be a cloth member or a plastic member, for example.

  As shown in FIG. 9B, when the subject measures the blood pressure by inserting the left arm into the armband portion 2, for example, the armband portion is passed through the finger F between the finger insertion portion 233B and the outer cloth 16. 2 can be securely held, and the armband portion 2 can be moved along the left arm. As a result, not only can the armband portion 2 be easily and reliably attached to the upper arm T, but the mounting direction of the armband portion 2 becomes clear by looking at the knob portion 233A. You can pass through your fingertips. For this reason, it can prevent that a to-be-measured person inserts a hand back into the armband part 2 accidentally from the opening part 11P side.

The opening closing member 30 of the armband portion 2 shown in FIG. 3 is not limited to a hook-and-loop fastener, and for example, an S-pole magnet can be used as one member and an N-pole magnet can be used as the other member.
Further, in another embodiment of the present invention shown in FIG. 10, a plastic armband portion 2 having a rigid outer side and a handle 2V can be used, and the microphone of the sphygmomanometer body or the armband portion can be used. The arrangement structure may be as described above. That is, as an embodiment of the sphygmomanometer of the present invention, the type in which the outer side of the above-described armband part is covered with a soft outer cloth, and the outer side of the armband part shown in FIG. Both types with surface members are included.
