The foregoing and other features of the invention will become apparent from the following description, taken with reference to the accompanying drawings. In the specification and drawings, specific embodiments of the invention are disclosed, which illustrate some embodiments in which the principles of the invention may be employed. It is to be understood that the invention is not limited to the described embodiments, but rather, the invention The invention includes all modifications, variations and equivalents that come within the scope of the appended claims.

Example 1

The embodiment of the present invention provides a nursing system, and Fig. 1 is a schematic diagram of the nursing system. As shown in Fig. 1, the nursing system 100 has a nursing bed 101 and a notification device 102, and the nursing bed 101 has a pressure sensor 1011 and a Device 1012, the pressure sensor 1011 is used to collect the pressure signal from the person being cared for. The care device 1012 is used to determine the first state of the care receiver based on the pressure signal, determine the second state of the care receiver based on the first state of the care receiver, and The first state and/or the second state are sent to the notification means. The notification device 102 is used to display the first state and/or the second state of the care receiver.

Through the care system of this embodiment, the status of the care receiver can be displayed on the notification device 102 to notify the caregiver.

In this embodiment, the pressure sensor 1011 may be arranged at a predetermined position under or inside the mattress of the nursing care bed. FIG. 2 is a side view of an embodiment of a mattress 200 installed with a pressure sensor 1011 , and FIG. 3 is a schematic plan view of the mattress 200 shown in FIG. 2 . As shown in FIGS. 2 and 3 , in this embodiment, four pressure sensors 1011 are arranged at predetermined positions below or inside the mattress 200 . When the caregiver lies or sits on the mattress 200 , A certain pressure will be generated on the mattress 200 , thus, through the pressure sensor 1011 arranged at a predetermined position below or inside the mattress 200 , a pressure signal from the person being cared for can be collected.

Fig. 2 and Fig. 3 take the integrated mattress as an example, however, the present embodiment is not limited to this, in the present embodiment, the care bed can be folded, lifted, movable (the bottom of the bed legs provided with sliding wheels), it can also be immovable (the bottom of the bed legs is not provided with sliding wheels), etc., correspondingly, the mattress placed on the nursing bed can also be of any shape, as long as it is placed under the mattress Or the pressure sensor 1011 at a predetermined position inside can sense and collect the pressure from the person being cared for, all of which are included in the scope of protection of the present application.

In this embodiment, since the force exerted on the mattress is different when the positional relationship between the person being cared for and the mattress is different, the nursing device 1012 can determine that the person being cared for is 1st status for caregivers. In this embodiment, there is no limitation on the way in which the care device 1012 determines the first state of the care receiver.

Fig. 4 is a flow chart of an embodiment of the first state of the nursing device 1012 judging the person being cared for, as shown in Fig. 4 , in this embodiment, the nursing device 1012 can obtain the pressure value collected by each pressure sensor (S401 ), compare the acquired pressure value of each pressure sensor with the judgment threshold corresponding to each pressure sensor (S402), and determine the first state of the care receiver according to the comparison result (S403).

In this embodiment, if the pressure values of each pressure sensor are greater than the corresponding determination threshold of each pressure sensor, and the difference between the pressure values of each pressure sensor is within a predetermined range, then the nursing device 1012 determines the first The state is sleeping in the central part; if the pressure value of each pressure sensor is greater than the corresponding judgment threshold of each pressure sensor, and the pressure value of the pressure sensor located on the left side of the nursing bed is greater than the pressure sensor located on the right side of the nursing bed pressure value, then the nursing device 1012 determines that the first state of the nursing person is sleeping on the left side; If the pressure value of the pressure sensor is greater than the pressure value of the pressure sensor on the left side of the nursing bed, then the nursing device 1012 determines that the first state of the person being cared for is sleeping on the right side; if the pressure value of each pressure sensor is greater than each The threshold value corresponding to the pressure sensor, and wherein the pressure value of one or more pressure sensors is greater than the pressure value of other pressure sensors, then the nursing device 1012 determines that the first state of the person being cared for is in the first state of the one or more pressure sensors Sitting nearby; if the pressure values of each pressure sensor are less than or equal to the judgment threshold corresponding to each pressure sensor, then the care device 1012 determines that the first state of the care receiver is leaving.

Still taking the four sensors shown in Figure 2 and Figure 3 as an example, when the person being cared for is sleeping in the central part of the nursing bed, the pressure signals collected by the four pressure sensors are roughly the same; When sleeping on the side, the pressure signals collected by the two pressure sensors on the left side of the mattress are greater than those collected by the two pressure sensors on the right side of the mattress; The pressure signals collected by the two pressure sensors on the right side are greater than those collected by the two pressure sensors on the left side of the mattress; when the caregiver sits on the nursing bed, the pressure signal collected by a certain pressure sensor is greater than The pressure signals collected by the other three pressure sensors; when the caregiver leaves the nursing bed, the signals collected by the four pressure sensors are relatively zero.

Thus, using the pressure signal collected by the pressure sensor, the care device 1012 can determine the first state of the care receiver, that is, sleeping in the center, sleeping on the left side, sleeping on the right side, sitting, or not on the bed.

In this embodiment, the nursing bed may also have a storage unit (not shown in the figure), which stores the determination threshold corresponding to each pressure sensor. In this embodiment, the determination threshold corresponding to each pressure sensor may be preset, or obtained through pre-measurement, for example, the average value and deviation of the pressure values of each pressure sensor in the absence of people are used as Decision threshold for each pressure sensor.

Still taking Fig. 2 and Fig. 3 as an example, as shown in Fig. 3, assuming that four pressure sensors A, B, C, and D are respectively arranged on the upper left, upper right, lower left, and lower right under or inside the mattress, in this embodiment In the process, the pressure value of each pressure sensor can be recorded first in the absence of people, and then the placement position of bedding (such as bedding, care products, etc.) The sum of the average value and the deviation of the pressure values of the pressure sensors is used as the judgment threshold of each pressure sensor. Wherein, the deviation refers to the maximum difference among the differences between each pressure value and the average value, and may be the absolute value of the maximum difference.

In this embodiment, if the average value of the pressure value of pressure sensor A is a1 and the deviation is a2, then the judgment threshold of pressure sensor A is a1+a2, and so on, the average value of the pressure value of pressure sensor B is b1 , the deviation is b2, then the judgment threshold of pressure sensor B is b1+b2, the average value of the pressure value of pressure sensor C is c1, and the deviation is c2, then the judgment threshold of pressure sensor C is c1+c2, the pressure of pressure sensor D is The average value of the value is d1, and the deviation is d2, then the judgment threshold of the pressure sensor D is d1+d2.

In this embodiment, the nursing device 1012 compares the measured pressure values a, b, c, and d of each pressure sensor with the judgment thresholds a1+a2, b1+b2, c1+c2, d1+d2 of each pressure sensor , to determine the first state of the care receiver.

Still taking the foregoing as an example, if the comparison result is: a1+a2<a, b1+b2<b, c1+c2<c, d1+d2<d, then the judging unit 403 judges that the person being cared for is on the nursing bed, and further , if the comparison result is: a=b, and c=d, then the nursing device 1012 determines that the cared person is sleeping in the central part of the nursing bed. Wherein, a=b, c=d may also be approximately equal, that is, the difference a-b between a and b is within a predetermined range, and the difference c-d between c and d is within a predetermined range.

Similarly, if the comparison result is: a1+a2<a, b1+b2<b, c1+c2<c, d1+d2<d, then the nursing device 1012 determines that the person being cared for is on the nursing bed. Further, if the comparison The result is: a>b, c>d, then the care device 1012 determines that the care receiver sleeps on the left side of the care bed.

Similarly, if the comparison result is: a1+a2<a, b1+b2<b, c1+c2<c, d1+d2<d, then the nursing device 1012 determines that the person being cared for is on the nursing bed. Further, if the comparison The result is: a<b, c<d, then the nursing device 1012 determines that the cared person sleeps on the right side of the nursing bed.

Similarly, if the comparison result is: a1+a2<a, b1+b2<b, c1+c2<c, d1+d2<d, then the nursing device 1012 determines that the person being cared for is on the nursing bed. Further, if the comparison The result is: a>b, a>c, a>d, then the nursing device 1012 determines that the care receiver is sitting near the pressure sensor A, or, if the comparison result is: b>a, b>c, b>d , then the care device 1012 determines that the care receiver is sitting near the pressure sensor B, and so on.

Similarly, if the comparison result is: a1+a2≥a, b1+b2≥b, c1+c2≥c, d1+d2≥d, then the nursing device 1012 determines that the person being cared for is not on the nursing bed, that is, the person being cared for Leaving the nursing bed.

With the care apparatus 1012 of this embodiment, it can be determined whether the first state of the care receiver is sleeping in the center, sleeping on the left side, sleeping on the right side, sitting or leaving. In this embodiment, four pressure sensors are taken as an example, but this embodiment is not limited thereto.

In this embodiment, the care device 1012 can determine the second state of the care receiver by using the first state of the care receiver determined by the care device 1012 . In this embodiment, there is no limitation on how the care device 1012 determines the second state of the care receiver.

Fig. 5 is the flow chart of an embodiment of the 2nd state that nursing device 1012 judges the person being cared for, as shown in Fig. 5, in this embodiment, this nursing device 1012 can count the time that the person being cared for maintains the first state ( S501), determine the second state of the person being cared for according to the statistical result (S502).

In this embodiment, if the time for the person being cared to leave the nursing bed, that is, the time for keeping the first state of leaving is equal to or exceeds a preset time, the nursing device 1012 determines the second time for the person being cared for. The status is Sleep Abnormal. If the time that the care receiver sits on the care bed, that is, the time of maintaining the first state of sitting is equal to or exceeds a preset time, the care device 1012 determines that the status of the care receiver is sleep abnormality. If the time for the person being cared to sleep in the same sleeping position (sleeping in the central part or sleeping on the left side or sleeping on the right side), that is, the time to keep the first state of sleeping in the central part or sleeping on the left side or sleeping on the right side is equal to or exceeds the preset time. In the case of a predetermined time, the care device 1012 determines that the second state of the care receiver is abnormal turning over. If the person being cared for changes between two or more first states, and the number of changes exceeds the predetermined number of times within a predetermined time period, that is, the person being cared for changes between any two or more of the above-mentioned first states, And if the number of changes within the predetermined time exceeds the predetermined number, the care device 1012 determines that the second state of the care receiver is abnormal activity. For example, if within one minute, the person being cared for has been changing between the three postures of sleeping on the left side, sleeping on the right side, and sleeping in the center, and the number of changes exceeds 10 times, then the nursing device 1012 determines that the person being cared for The status of the person is Active Abnormal.

Thus, using the first state of the care receiver determined by the care device 1012, the care device 1012 can determine the second state of the care receiver.

In this embodiment, the nursing device 1012 can have a first wireless communication module, such as a wifi module, which can send the first state of the care receiver determined by the nursing device 1012 to the notification device 102, so as to notify the device 102 Notify the caregiver of the first state of the care receiver.

In this embodiment, the care device 1012 can also have a second wireless communication module, such as a wifi module, which can send the second status of the care receiver determined by the care device 1012 to the notification device 102, so as to notify the device 102 Notifies the caregiver of the second status of the care receiver.

In this embodiment, the notification device 102 can display the first status and/or the second status of the care receiver, so as to notify the care staff of the status of the care receiver, so that the care staff can State 1 and/or State 2 make timely processing.

In this embodiment, the nursing device 1012 may be composed of software or hardware, such as circuits.

In this embodiment, the notification device 102 may display the first status and/or the second status of the care receiver, so as to notify the care staff of the status of the care receiver.

Fig. 6 is a composition schematic diagram of an embodiment of the notification device 102, as shown in Fig. 6, in this embodiment, the notification device 102 is composed of an electronic device 601, and the electronic device is, for example, a mobile phone of a caregiver or a monitor of a caregiver device, etc., the electronic device 601 can display the first status and/or the second status of the care receiver.

Fig. 7 is a schematic composition diagram of another embodiment of the notification device 102, as shown in Fig. 7, in this embodiment, the notification device 102 is composed of a server 701 and an electronic device 702, and the server 701 can send the The first state and/or the second state of the electronic device 702 is sent to the electronic device 702, so that the electronic device 702 can display the first state and/or the second state of the care receiver.

In one embodiment, as mentioned above, the first state of the care receiver is sleeping in the central part, sleeping on the left side, sleeping on the right side, sitting or leaving, then the electronic device 601/702 can display the first state , optionally, the duration of the first state can also be displayed, so that the caregiver can understand the current state of the care receiver.

In one embodiment, as mentioned above, if the second state of the care receiver is abnormal sleeping, abnormal turning over, or abnormal activity, the electronic device 601/702 can display the second state, and optionally, can also display The duration of the second state, so that the caregiver understands the current state of the caregiver so as to deal with it in time.

For example, if the person being cared for has left the nursing bed (the first state is "leave"), and keeps such a state for more than a predetermined time (the second state is "abnormal sleep"), then the electronic device 601/702 can display "leave". ” and/or “The person in care may be wandering”.

For example, if the person being cared sits in a certain position of the nursing bed (the first state is "sitting"), and keeps such a state for more than a predetermined time (the second state is "abnormal sleep"), then the electronic device 601 /702 can display information such as "sitting" and/or "an abnormal state that cannot sleep may have occurred".

For example, if the caregiver maintains the same sleeping posture for more than a predetermined time (the first state is "sleep on the left side or right side or central part"), the electronic device 601/702 can display "sleeping on a certain side" and/or Or information such as "It is possible that an abnormal state that cannot be turned over has occurred".

For example, if the person being cared for changes between two or more first states in the above-mentioned five first states, and within the set time, the number of changes exceeds the set number of times, then the electronic device 601/702 can display " The care recipient may be moving around on the care bed" message.

The above is an example of the notification device 102 displaying information related to the status of the care receiver, but this embodiment is not limited to this. In other implementations, the notification device 102 can also send an alarm signal to notify the care personnel Notify the status of the care receiver. As a result, the caregiver can know the state of the care receiver in time, and when something happens to the care receiver, he can deal with it in time, which improves the efficiency of care. Moreover, since the pressure signal is only transmitted through the pressure sensor without a camera, the privacy of the person being cared for is avoided, and the technical problem to be solved in the background art is solved.

In this embodiment, the server 701 can be set locally or on a remote cloud, as long as it has the functions of the server 701 of the present application, it can function as the server 701 of the present application.
