Fluid exhaustion notification device {ALARM APPARATUS FOR EXHAUSTED OF INFUSION SOLUTION}

The present invention relates to a fluid exhaustion notification device, and more particularly, when the fluid is administered to a certain purpose is exhausted by informing the patient of the patient or the caregiver or caregiver who cares for the patient at a short or long distance The present invention relates to a sap exhaustion notification device that provides stability and reliability to patients receiving and can prevent safety accidents that may occur due to exhaustion of sap.

A fluid set is a device for administering a certain solution to the body for nutritional supplementation or oxygen supply by using the potential energy of the fluid and the pressure difference in the blood vessel. The infusion set includes a container for storing the infusion, a needle for injecting the infusion into the vein or subcutaneously, and a catheter in the form of a tube connecting the infusion container and the needle.

The conventional general fluid set as described above is inconvenient to adjust the administration time by the empirical and sensory method of the operator, the patient or the caregiver to observe the administration of the fluid at all times.

In order to solve the above problems, Korean Utility Model Publication No. 1999-38038 (the name of the draft: Sap Set Sap Automatic Detection Alarm Device) is provided with an infrared sensor composed of a light emitting part and a light receiving part at the bottom of the infusion container. An alarm device has been proposed to warn burnout. In addition, Korean Utility Model Publication No. 1996-13407 (designation of sap amount supplying device of sap set) proposes a sap set sensing device of a sap set having a sap detecting means composed of a pair of iron needles.

However, the alarm device proposed in the Korean Utility Model Publication No. 1999-38038 has a problem in that the positions of the light emitting unit and the light receiving unit are unclear, and malfunctions due to light flowing from the outside. In addition, the sap amount detection device proposed in the Korean Utility Model Publication No. 1996-13407 has a problem of leakage of fluid and hygiene because a pair of iron needles must be inserted into the sap container.

The present invention is to solve the above problems, an object of the present invention is to alert the patient or the caregiver or caregiver who is taking care of the patient at the close or long distance when the fluid administered for a certain purpose is exhausted. Thus, to provide a sap exhaustion notification device that provides stability and reliability to the patient receiving the sap, and can prevent in advance a safety accident that may occur due to the exhaustion of the sap.

In addition, when a magnetic sensor is used, a magnet having a predetermined magnetic force is attached to the infusion support 72 to detect the position of the infusion support 72.

4 is a state diagram used in the sap exhaustion notification device according to an embodiment of the present invention. Referring to FIG. 4, the operation of the present invention will be described, and the sap container 94 in which a predetermined amount of the sap is stored is mounted on the sap holder 71 and the sap hanger 73, and is mounted through the selection button 42. The amount of the fluid container 94 is selected. That is, pressing the select button 42 once selects 500 ml of PET material, and pressing twice selects 1000 ml of PET material.

After that, the drain hose 93 is placed on the solenoid valve 81 and then injected into the fluid solution. If the installed sap is continuously administered in the human body, the weight of the sap is gradually reduced and the sap support 72 is moved upward by the elasticity of the spring 76. The infusion support 72 to be moved is detected by the sensor (83) installed in the guide (74, 75) its position, the detected signal is input to the microcomputer 30, the selection button 42 in the microcomputer (30) By reading the signal of the sensor in accordance with the fluid volume selected through the to output a control signal to flash the warning light (31).

Accordingly, the patient or guardian detects the exhaustion of the fluid and replaces it. If the warning lamp 31 is not detected, the fluid support 72 continues to move upwards, and detects the sensor ( 83 outputs a detection signal to the microcomputer 30. The microcomputer 30 receiving the detection signal turns on the alarm lamp 32 and outputs an alarm sound through the speaker 91, and at the same time, wirelessly exhausts the sap to the guardian or the nurse through the wireless transmitter 60. You will be informed. At this time, the wireless transmitter 60 inputs a predetermined number to the microcomputer 30 in advance, and the microcomputer 30 transmits the corresponding number through the antenna 61. In addition, it can be easily implemented by those skilled in the art that SMS (Short Message Services) can be used through the microcomputer 30.

In addition, after a predetermined time after outputting the alarm signal through the alarm lamp 32 and the speaker 91, the sap of the infusion container 94 is completely exhausted, the microcomputer 30 drives the solenoid valve 81 The drain hose 93 is squeezed by outputting a control signal to stop the supply of the sap.

The sensor 83 is referred to as a sensor installed on the upper side # 1 and # 1 ~ # 7 is preferably installed, and operate as shown in Table 1 below according to the selected capacity.

Set value # 2 (500 ml) # 3 (1000 ml) # 4 (100 ml) # 5 (250 ml) # 6 (500 ml) Warning # 3 #4 # 5 # 6 # 7 Alarm operation #2 # 3 #4 # 5 # 6 Wireless transmission #2 # 3 #4 # 5 # 6 Shut off signal (solenoid valve operation signal) #One #2 # 3 #4 # 5

When 500ml is selected through the selection button 42 as shown in Table 1, the control signal is received from the microcomputer 30 to operate based on the sensor # 2. That is, when the detection signal of the sensor # 3 is input, the signal to flash the warning light 31 is output from the microcomputer 30, and when the detection signal of the sensor # 2 is input, the alarm lamp 32 is output from the microcomputer 30. It turns on, outputs an alarm sound through the speaker 91, and outputs the sap exhaustion signal through the wireless transmitter (60). When the detection signal of the sensor # 1 is input, the drain hose 93 is compressed by outputting a signal for operating the solenoid valve 81.

In addition, when the sap support 72 is repeatedly used for a long time, the elasticity of the spring 76 is changed. Therefore, a malfunction occurs due to the elasticity of the changed spring 76, so that after a certain period of time, the prepared weight is mounted on the infusion holder 71 to adjust the adjustment bolt 78 connected to the spring 76 through the adjustment nut 82. To adjust the tension. In addition, the discharge lamp 13 installed on the front is turned on when the output power of the battery mounted on the internal battery case 14 is below a certain level. In addition, the battery of the battery case 14 may be configured as a storage battery to be charged through the DC power input terminal 15 mounted on the side.

In addition, the infusion support 72 may be configured to be connected to the load shell to operate as a sensor signal of the load shell, the infusion holder 71 may be configured to take the infusion container 94 by forming a constant ring Those skilled in the art will be able to easily practice.

An embodiment of the present invention described above and illustrated in the drawings should not be construed as limiting the technical spirit of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention, as will be apparent to those skilled in the art.

According to the present invention, when the fluid to be administered for a certain purpose is exhausted, the patient or the caregiver or caregiver who cares for the patient at a short or long distance to alert the exhausted state of the fluid, to ensure stability and reliability to the patient receiving the fluid It is possible to prevent and prevent accidents that may occur due to exhaustion of the sap.
