Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a turnover monitoring device and system used for care and nursing of bedridden elderly people and critically ill patients, and a pressure ulcer prevention method.
[0002]
[Prior art]
In recent years, as the population ages, the issue of nursing care for the elderly has been taken up. For this reason, various approaches have been taken to care for the elderly, and among them, patrol care by caregivers or the like having specialized knowledge and skills is common. In such traveling care, a caregiver regularly visits the home of an elderly person or the like to provide a detailed service.
[0003]
In recent years, in order to efficiently perform such patrol care, systematization of care has been promoted using, for example, a computer or a communication terminal.
[0004]
However, when attempting to systematize care in this way, the care center generally manages information on the care receiver, etc., so that the care giver goes to the management center to collect information on the care receiver, etc. The inconvenience that it is necessary to do it arises.
[0005]
In order to solve such inconveniences, a remote monitoring system has been proposed that can automatically monitor and monitor a cared person or the like, and automatically notify a support center or the like when an abnormality occurs (for example, a remote monitoring system). And Patent Document 1).
[0006]
Specifically, this remote monitoring system constantly monitors the usage current of home electric appliances installed in the home of the care-receiver, the movement of the body of the care-receiver, and the like with a detector. The care service provider side server is notified of the fact by such means, and the caregiver rushes to the care receiver's home, gives instructions for medication, and arranges an ambulance.
[0007]
However, such a remote monitoring system can support the care of a cared person who can get up and live on their own, but, for example, a bedridden elderly person or a seriously ill patient who is bedridden due to an accident or illness. It cannot be applied to nursing care / nursing of care recipients.
[0008]
By the way, in bedridden care receivers, it is necessary to prevent pressure ulcers (bed sores) caused by not turning over for a long time. Here, pressure ulcers are caused by clothing or bedding, etc., where the elderly or severely ill patients keep a specific position for a long time without turning over, and the skin is pressed by clothing, bedding, etc., and impaired blood flow in the pressed portion. It is a type of compression gangrene.
[0009]
[Patent Document 1]
JP-A-2002-157334 (FIGS. 1 and 2)
[0010]
[Problems to be solved by the invention]
In conventional pressure ulcer prevention, pressure ulcers occur immediately if the body is not repositioned even once, so if the elderly and critically ill patients are aware of their postures at the time of sleep and turnover in advance, If it is determined, it is necessary for the caregiver or nurse to periodically change the position. Actually, the fact that the rollover is determined depends on the intuition (experience) of the caregiver or nurse.
[0011]
Therefore, when turning over of the elderly or critically ill patients is decreasing, there is a problem that pressure ulcers are likely to occur, so that the burden of nursing care and nursing monitoring increases sharply, resulting in high costs.
[0012]
In addition, the elderly population requiring nursing care is steadily increasing as the population ages, and the public nursing care insurance system currently introduced is cost-effective to respond to such an increase in the elderly population. It is difficult to do so, and there is a demand for lower costs for nursing care and the like.
[0013]
In view of such circumstances, an object of the present invention is to provide a turnover monitoring device and system, and a pressure ulcer prevention method that can significantly reduce the burden of nursing care and nursing and reduce costs.

[0026]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0027]
(Embodiment 1)
FIG. 1 is a block diagram illustrating a configuration of a turnover monitoring device according to Embodiment 1 of the present invention.
[0028]
The turnover monitoring device of the present embodiment is a device that monitors whether or not a bedridden human body has turned over.For example, the device is attached to the body of an elderly person, a severely ill patient, or the like, and monitors the turnover to provide nursing care. It is intended to prevent pressure ulcers by reducing the monitoring burden on the elderly.
[0029]
Specifically, as illustrated, the turnover monitoring device 10 includes a detection sensor 20 that detects a position change when the bedridden human body 1 turns over, and uses the data detected by the detection sensor 20 as turnover information data. And a control unit 40 having a turning information processing means 30 for determining whether or not the human body 1 has turned over by processing.
[0030]
The detection sensor 20 is attached to the human body 1 and detects one or both of the inclination and the movement of the human body 1. Examples of such a detection sensor 20 include a sensor that detects the inclination of the human body 1 using at least one selected from a rotary encoder, an accelerometer, a vibration gyro sensor that detects an angular velocity of an object, and the like. The sensor is not particularly limited as long as the sensor can detect various data such as the tilt angle of the human body 1 from the stationary state to the left and right, the angle at which the body is raised, the speed of these movements, and the turning direction. Absent. In the present embodiment, a rotary encoder is used as the detection sensor 20, and there are an incremental type and an absolute type as the rotary encoder. Here, the incremental type is used.
[0031]
Here, with reference to FIG. 2, the detection sensor 20 including an incremental type rotary encoder will be described. FIG. 2 is a schematic configuration diagram illustrating an example of the detection sensor according to the first embodiment of the present invention.
[0032]
As shown in FIGS. 2A to 2C, the detection sensor 20 according to the present embodiment includes a rotary encoder 22 and a rotary weight 24 attached to a tip of a rotary shaft 23 of the rotary encoder 22. And is fixed inside the housing 25.
[0033]
Although not shown, the rotary encoder 22 is provided with vertical scales and slits on a rotating disk at equal intervals, and detects light from a light emitting diode (LED) or the like passing through the slits or the like as current with a phototransistor or the like, and And outputs the detected current as a rectangular wave (pulse). The output is a digital signal consisting of the A phase, the B phase having a phase difference of 90 °, and the Z phase indicating the origin, and the two rectangular waves of the A phase and the B phase are shifted by 90 ° in phase. By being output, the rotation direction of the rotation shaft 23 can be known. In addition, the rotation angle obtained by dividing one round by the number of vertical stripes is the detection accuracy. Note that such a rotary encoder outputs a pulse only while the rotating shaft is rotating, and detects the tilt angle by accumulating generated pulses, for example, by counting the number of pulses.
[0034]
On the other hand, the rotary weight 24 attached to the rotary shaft 23 of such an incremental type rotary encoder 22 has a shape whose outer shape is gradually increased outward in the radial direction from a portion fixed to the tip of the rotary shaft 23. I have. That is, the weight of the rotating weight 24 is larger at the tip end than at the side fixed to the rotating shaft 23. Therefore, when the direction of the entire detection sensor 20 changes, the rotary weight 24 rotates about the portion fixed to the rotary shaft of the rotary encoder 22 as the rotation center, and the tip end of the rotary weight 24 moves in the vertical direction. It has become. Therefore, if such a detection sensor 20 is attached to the human body 1, the rotating weight 24 rotates with the turning of the human body 1, and the rotating shaft 23 of the rotary encoder 22 rotates together with the rotating weight 24. Accordingly, when the human body 1 turns over, the rotary encoder 22 detects the A-phase to Z-phase rectangular waves as digital signals, and obtains the rotation direction by analyzing the phase difference between the A-phase and the B-phase. it can. Then, the two rectangular waves of the A phase and the B phase are counted by an up / down counter or the like, and by analyzing this count value, the turning angle of the human body 1 can be obtained.
[0035]
Actually, such a detection sensor 20 outputs a digital signal composed of the A phase, the B phase and the Z phase to the turnover information processing means 30 via the signal output means 21 described later. If the digital signal is processed and analyzed, it is possible to determine whether or not the human body 1 has turned over, as will be described in detail later. Further, the digital signal is transmitted to the outside 50 via the data transmitting means 42. The turning of the human body 1 can be monitored.
[0036]
As described above, in the present embodiment, the incremental type rotary encoder 22 has been described as the detection sensor 20. However, an absolute type may be used. Alternatively, an accelerometer and a vibration gyro sensor for detecting the angular velocity of an object may be used. Needless to say, such as may be used. Note that the vibration gyro sensor is a gyro sensor using a vibrator as a detection element.
[0037]
The detection sensor 20 includes a signal output unit 21 that outputs the various data described above to the turnover information processing unit 30. Such a signal output unit 21 is connected to the turnover information processing unit 30 via a wire or wirelessly, and outputs various data detected by the detection sensor 20 to the turnover information processing unit 30 of the control unit 40.
[0038]
On the other hand, the control unit 40 includes a turnover information processing unit 30, a data storage unit 41 for storing turnover information data, a data transmission unit 42 for transmitting the turnover information data to the outside 50, and a data display unit for displaying the turnover information data. 43.
[0039]
In the present embodiment, for example, the turnover information processing unit 30 is mounted at a location away from the human body 1, that is, at a location away from the detection sensor 20, and processes data detected by the detection sensor 20 as turnover information data. To determine whether the human body 1 has turned over.
[0040]
More specifically, the turning information processing means 30 processes the various data detected by the detection sensor 20 as turning information data, and determines, for example, the number of turning times, the turning angle, the turning direction, the turning time, and the like. 31.
[0041]
The data processing unit 31 receives various data output from the signal output unit 21 of the detection sensor 20 and processes the input various data into turning information data via, for example, an analog circuit or a digital circuit. Has a function of determining whether or not the human body 1 has turned over based on the obtained turnover information data.
[0042]
Here, the term “turning over” refers to a change of body position in which the body is turned while lying down. For example, the body leans left or right with respect to the center (spine) of the body of an elderly person or a severely ill patient, It indicates that the posture is changed from the body position to the prone position.
[0043]
Since there is an individual difference in such turning, it is preferable that the basic posture of each individual at the time of sleeping or turning is grasped in advance, and the presence or absence of the turning is determined in consideration of such basic posture. Therefore, for example, in the present embodiment, together with the data processing unit 31 described above, a setting unit 32 capable of freely setting how or how much the body should be moved and then detected as one rollover is provided.
[0044]
Such a setting unit 32 can set a range in which the change of the body position of the human body 1 is detected as a rollover. For example, when the human body 1 is tilted by a predetermined angle or more to one of the left and right sides from the supine position, one turnover is performed. May be detected. Further, a case where the human body 1 stands up or a case where only the upper body is raised may be detected as one turn. Furthermore, when the human body 1 gets up, the detection of the turning over may be stopped, and in this case, the detection of the turning over may be started when the human body 1 goes back again.
[0045]
In the setting unit 32, various conditions for the data processing unit 31 to determine one turn based on the turn information data are set. That is, for example, various data such as the number of times of turning and the turning angle are set to predetermined values. When the value is equal to or more than the value, it is possible to make settings for judging that one turn is performed.
[0046]
The turning information processing means 30 converts various data output from the signal output means 21 of the detection sensor 20 to the data processing means when the detection sensor 20 cannot detect the turning of the human body 1 for a predetermined time or more. After the data processing at 31, it has a function of automatically transmitting the obtained turning information data to the outside 50 via the data transmitting means 42. At this time, as the turnover information data transmitted to the outside 50, for example, data that the number of times of turnover is 0 is transmitted.
[0047]
Examples of the data storage unit 41 include, for example, general recording devices such as a ROM and a RAM, but are not limited thereto. The turnover information data stored in the data storage means 41 is used as a material for determining whether or not an elderly person, a severely ill patient, and the like easily develop a pressure ulcer.
[0048]
In the present embodiment, the turnover information processing means 30 having such a configuration is placed at a place remote from the human body 1, but is integrated with the detection sensor 20, that is, the human body 1 together with the detection sensor 20. It may be attached to.
[0049]
In this embodiment, a data transmission unit 42 is connected to the turnover information processing unit 30, and the data transmission unit 42 transmits turnover information data to the outside 50. The data transmission unit 42 is not particularly limited as long as it is a unit that performs communication using at least one of communication units such as wireless, infrared, Internet, and software. Note that the outside 50 is, for example, a monitoring center, a caregiver, a traveling care vehicle, a medical institution, a care company, and the like, which will be described later.
[0050]
Further, in the present embodiment, the control unit 40 has a data display unit 43 that displays the turning information data stored in the data storage unit 41. Therefore, it is possible to visually refer to the turnover information data via the data display means 43. Therefore, if the turnover monitoring device 10 of the present embodiment is used in a medical facility such as a hospital, for example, when a doctor or a nurse or the like patrols a patient, the turnover status of an elderly person or a severely ill patient is displayed via the data display means 43. Can be confirmed immediately, so that the monitoring burden can be reduced and the occurrence of pressure sores can be effectively prevented.
[0051]
Here, a turnover monitoring system using the above-described turnover monitoring device 10 will be described with reference to FIGS. FIG. 2 is a schematic configuration diagram of the turnover monitoring system. FIG. 3 is a flowchart illustrating a process in the turnover monitoring system.
[0052]
As shown in FIG. 2, the turning-over monitoring system of the present embodiment includes the above-described turning-over monitoring device 10 and a notifying unit 60 that performs a predetermined notification based on information from the turning-over information processing unit 30.
[0053]
The notifying unit 60 has a function of notifying a nearby person, such as a caregiver or a nurse, by setting when the detection sensor 20 cannot detect the turning over of the human body 1 even after a predetermined time has elapsed. For such a predetermined notification of the notification means 60, for example, an alarm or the like may be used, and, of course, the data transmission means 42 or the data display means 43 described above may be used.
[0054]
In the present embodiment, the occurrence of pressure sores is prevented by monitoring the turning of the human body 1 using such a turning monitoring system.
[0055]
Specifically, as shown in FIG. 3, first, the setting unit 32 of the turnover monitoring device 10 sets a range to be determined as a turnover in consideration of the positions of the human body 1 at the time of going to bed and at the time of turning over. Then, the detection sensor 20 is attached to a human body, and the control unit 40 is installed at a predetermined position (step S1). Here, the detection sensor 20 manufactured using the above-described incremental type rotary encoder was mounted on the abdomen of the human body 1, and the control unit 40 was installed at a location away from the human body. Then, the detection sensor 20 and the control unit 40 were connected via radio. Thus, the turning monitoring apparatus 10 of the present embodiment can monitor the turning of the human body 1.
[0056]
Next, the detection sensor 20 detects various data such as the turning angle of the human body 1 (step S2). Here, as described above, the detection sensor 20 using the rotary encoder 22 detects a digital signal for analyzing the inclination of the human body 1, that is, the turning angle and the turning direction. More specifically, the A-phase, B-phase, and Z-phase rectangular waves (pulses) indicating the rotation angle of the rotary shaft of the rotary encoder 22 are detected as digital signals. Then, after outputting the digital signal to the turning information processing means 30 by the signal output means 21, the data processing means 31 of the turning information processing means 30 performs data processing of the digital signal as turning information data (step S3). The data processing unit 31 performs data processing on the digital signal detected by the detection sensor 20, that is, the A-phase, B-phase, and Z-phase rectangular waves (pulses) to obtain the turning angle and turning direction of the human body 1 as turning information data. I do. Specifically, as described above, the number of A-phase and B-phase pulses is counted, and the rotation angle of the rotating shaft, that is, the turning angle, is acquired from the count value and the scale of the slit, and the A-phase and B-phase are obtained. The turning direction is obtained from the phase difference of. In this step S3, the data processing means 31 stores the turning information data in the data storage means 41 (step S4).
[0057]
Next, the data processing means 31 determines whether or not the human body 1 has turned over based on the turnover information data (step S5). Note that the presence or absence of turning over is determined based on the condition set by the setting unit 32 described above. Here, when it is determined that the vehicle has been turned over (Yes), the elapsed time from the start of the detection of the overturn, that is, the predetermined time serving as a reference for performing a predetermined notification in steps described later is reset (step S6) Then, returning to step S2, the detection of the turning angle is started, and the counting of the predetermined time is also started. Conversely, when it is determined that the user has not turned over (No), it is determined whether a predetermined time has elapsed since the start of the detection of turning over (step S7). When it is determined that the predetermined time has not elapsed (No), the process returns to step S2, and the detection of the turnover angle is started again. A predetermined notification is issued.
[0058]
Here, as examples of the predetermined notification by the notification unit 60, notification to the outside 50, notification by an alarm, and notification by the data display unit 43 will be described.
[0059]
In the notification to the outside 50, first, when a predetermined time has elapsed since the data processing unit 31 started to detect a turn, for example, the turn information data that the number of times of turn is 0 is sent to the outside 50 via the data transmission unit 42. (Step S8). Next, the external unit 50, for example, the monitoring center, which has received the turnover information data, will be described in detail later. A dispatch command is issued for turning over (step S9). Then, the caregiver or the like who has received such a dispatching instruction forcibly changes the position of the human body 1, that is, turns over (step S10).
[0060]
In the notification by the alarm, first, when a predetermined time has passed since the data processing means 31 started to detect a turn, a signal to that effect is output to the notification means 60 (step S11). Next, the notifying means 60 which has received this signal sounds an alarm (step S12). Then, a caregiver or the like in the vicinity who notices the alarm forcibly turns over (step S10).
[0061]
Further, in the notification by the data display means 43, when a predetermined time has elapsed since the data processing means 31 started to detect a turn, for example, the data display means 43 displays turn data indicating that the number of times of turn is visually recognized by the caregiver or the like. The information is displayed so that it can be referred to (Step S13). Then, the caregiver or the like who refers to the turning information data via the data display means 43 forcibly turns the human body 1 (step S10).
[0062]
Note that each of these notifications may be appropriately selected according to the usage mode of the turnover monitoring system, and is, of course, not limited thereto. For example, if the notification by the data display unit 43 or the alarm has passed for a certain period of time or more and it is not possible to turn over, the notification to the outside 50 may be executed.
[0063]
Here, with reference to FIGS. 1, 2, and 4, a description will be given of an aspect in which the monitoring center, which is the outside 50 that has received the turnover information data, issues a dispatch instruction to a caregiver or the like. FIG. 4 is a schematic diagram for explaining a mode when a dispatch instruction is issued to a caregiver.
[0064]
As shown in the figure, when the turnover information data detected using the turnover monitoring device 10 described above is transmitted to the monitoring center 100 via the data transmission unit 42, the received monitoring center 100 performs the conversion based on the turnover information data. In order to forcibly change the position of the human body 1, dispatch instructions A to D are issued to the caregiver 110 and the like.
[0065]
The monitoring means 101 of such a monitoring center 100 includes a data acquisition means 102 for acquiring turnover information data and a dispatch instruction transmission means 103 for transmitting dispatch instructions A to D for causing a caregiver or the like to turn over the human body 1. Have.
[0066]
Specifically, when the turning-over monitoring device 10 mounted on the human body 1 does not detect turning over even after a predetermined time has elapsed, the turning-over information data is transmitted to the monitoring center 100 via the data transmitting unit 42. Then, in the monitoring center 100, after the turnover information data is acquired by the data acquisition unit 102, based on the turnover information data received by the dispatch command transmission unit 103, for example, when it is determined that the turnover is necessary, When a care request is received, dispatch instructions A to D are transmitted to the caregiver 110, the patrol car 120, the medical institution 130, the care company 140, and the like.
[0067]
Then, for example, the caregiver 110 or the patrol car 120 that has received the dispatch instructions A and B rushes to the human body 1 and forcibly turns over. Further, the medical institution 130 that has received the dispatching instruction C dispatches a nurse or the like to the human body 1 to force a turnover. Further, the care company 140 that has received the dispatching instruction D dispatches a helper or the like under the human body 1 and forcibly turns over.
[0068]
In addition, the monitoring center 100 of the present embodiment includes a cost management unit 104 that manages costs based on dispatch commands A to D for turning over the human body 1.
[0069]
For example, in the present embodiment, the cost management means 104 transmits the basic charge as the monitoring charge and the dispatch instructions A to D to the caregiver 110 and the like in order to force the human body 1 to turn over. It manages the dispatch fee when dispatched.
[0070]
For example, it is very economical to leave the care to a family member (relative) when the care is possible, and to dispatch the caregiver 110 or the like only when care is impossible.
[0071]
That is, in the above-mentioned turnover monitoring system, for example, the dispatcher performs the minimum nursing and nursing only when necessary, so that the dispatch management fee is added to the basic fee only when dispatched, due to the expense management of the expense management means 104. It is very economical to pay only for the nursing care required. Further, the charge system in the cost management means 104 can be automatically and interlocked and managed by a computer or the like. That is, according to the present invention, the cost is very economical, the monitoring burden of care and nursing can be reduced, and the management is efficient, so that excellent effects can be realized.
[0072]
As described above, according to the turnover monitoring system of the present embodiment, in order to send the caregiver 110 or the like to the human body 1 using the turnover monitoring device 10, the dispatch command A is sent to the caregiver 110 or the like. Since ~ D is transmitted and the human body 1 is forcibly turned only when necessary, the occurrence of pressure sores can be efficiently and completely prevented.
[0073]
In addition, since the turning over can be automatically monitored by using the turning over monitoring device 10 and the dispatch commands A to D can be transmitted automatically, the monitoring burden on the caregiver 110 and the like can be reduced, and the cost required for the care and nursing can be reduced to the necessary minimum. Can be minimized.
[0074]
(Other embodiments)
As described above, the embodiment of the present invention has been described. However, the turnover monitoring device, the turnover monitoring system, and the pressure ulcer prevention method are not limited to those described above.
[0075]
For example, in the above-described embodiment, a turnover monitoring system that dispatches a caregiver 110 or the like via the monitoring center 100 has been described as an example. However, the present invention is not limited thereto. A turnover monitoring system that directly transmits turnover information data to a caregiver or the like may be used. In this case, the caregiver or the like who has received the turnover information data may determine the necessity of turning over without making the determination by the data processing means. Alternatively, the necessity of turning may be determined in advance by the turning monitoring device, and a dispatch command may be issued to the caregiver or the like instead of the turning information data only when the turning monitoring device determines that dispatch is necessary.
[0076]
【The invention's effect】
As described above, according to the present invention, a detection sensor that detects a change in body position of a human body, and a turnover that determines whether the human body has turned over by processing data detected by the detection sensor as turnover information data.
