Description

  The present invention relates to a technique for monitoring a posture of a patient at home, a medical facility, a nursing facility, or the like.

  For patients whose posture cannot be changed by themselves, it is usually necessary to change the posture of the patient regularly (with posture change) with the assistance of a caregiver or nurse to prevent bed slipping. . There are also many devices that technically support prevention and prevention of bedsores.

  For example, Patent Document 1 discloses an apparatus for preventing bed slipping by measuring body pressure distribution using an unconstrained biosensor laid on a bed or a futon and controlling the pressure of the mat. Further, in Patent Document 2, an air mat in which a plurality of cells are provided in the height direction when the patient is sleeping, a pressure sensor that detects a pressure distribution acting between each cell and the patient, and each cell are connected. An air mat device including an air supply / discharge device that supplies / discharges air to / from each cell is disclosed.

  Patent Document 3 discloses a bed slip notification system including a portable transmitter attached to each patient, receivers installed at a plurality of locations in a ward, and a monitoring device installed at a nurse center on each floor. Has been. The portable transmitter detects the acceleration acting on the patient and is sent to the monitoring device via the receiver, and the monitoring device detects the risk and abnormality of the patient's bed slippage based on the acceleration, Display on warning screen. Thereby, even if a caregiver or a nurse is out, it can be notified that there is a risk of bed slipping.

  However, Patent Documents 1 and 2 are based on the premise that the patient is in the supine position (upward), and prevent bedsores by controlling the pressure of a mat or the like without intervention of a caregiver or the like. In this regard, in the field of medical care, it is a principle to prevent bedsores through the use of caregivers and the like (for example, the patient's body is periodically rotated). There is no medical or nursing care that is carried out without human intervention by a caregiver or the like in the supine position. That is, in view of the actual situation of medical care, as in Patent Documents 1 and 2, the method of providing patient care support without human intervention is not a realistic measure, and is based on the presence of caregiver assistance. It is desirable to provide care support measures.

  Further, as disclosed in Patent Document 3, it is burdensome for the patient to put a specific device on the patient as means for detecting the body posture, which is not realistic. In other words, it will promote blood congestion. Further, in Patent Document 3, it is determined whether or not the lying person has turned over within a predetermined time. It does not monitor the conversion and the integrity of the actual patient position. For this reason, it cannot be said that the patient's postural change is sufficiently monitored.

The present invention has been made in view of the above-described problems, and its object is as follows.
It is intended to provide a posture monitoring apparatus and the like that monitor the consistency between a planned posture change and an actual posture without wearing a specific device on a patient, and prevent an assistance error or the like.

Is desirable. Thereby, a patient's posture can be detected suitably using the pressure sensor provided in the sheet.
Moreover, it is desirable that a plurality of grooves are formed in a certain direction on the surface of the sheet. As a result, since the seat has a mechanism that is easy to slide in a certain direction, even when the caregiver physically rotates the patient, the patient can be rotated in a certain direction with a small force. The burden of nursing care is greatly reduced.

  In the first invention, it is preferable that the detection means starts detecting the posture of the patient after a predetermined time has elapsed since the scheduled posture change time. Thereby, the detection of the patient's posture can be started in consideration of the time required for the caregiver or the like to change the patient's posture.

A second aspect of the present invention is a posture monitoring method executed by a computer including storage means for storing a schedule of posture change, and a detection step of detecting the posture of a patient;
A determination step for comparing the detected posture and the schedule for the posture change to determine whether or not the posture is normal; and a notification step for performing a predetermined notification when the determination means determines that the posture is not normal. , Including a position monitoring method.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of the present invention (referred to as “this embodiment”) will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram illustrating an outline of a body posture monitoring apparatus 1 according to the present embodiment. The posture monitoring device 1 is a device for monitoring a change in the posture of a patient at home, a medical facility, a nursing facility, or the like. Postural change refers to changing the position on a regular basis with the assistance of a caregiver or nurse to prevent bed slips, blood circulation problems, pain, sensory palsy, etc. of persons who cannot change their position by themselves.

  The body position monitoring device 1 includes a seat 5 and a control terminal 3 on which a patient can lean. The control terminal 3 acquires pressure data (pressure distribution) from a plurality of pressure sensors 7 provided on the seat 5 and detects the posture of the patient leaning on the seat 5. The control terminal 3 compares the detected posture (detected posture) with the posture (planned posture) planned in the posture conversion schedule table 20 (see FIG. 6), and determines whether or not the detected posture of the patient is normal. (Whether or not the detected body position matches the planned body position) is determined. When the control terminal 3 determines that the posture is not normal, the control terminal 3 performs a predetermined notification. Thereby, the caregiver or the like is notified of the abnormality of the patient's posture.

  The sheet 5 is formed by providing a large number of pressure sensors 7 (sensor array) on a flexible printed circuit (FPC). The pressure sensor 7 is, for example, [http://www.aist.go.jp/aist_j/press_release/pr2012/pr20120608/pr20120608.html] (Developed a flexible pressure sensor array from polyamino acids, published on June 8, 2012) Are formed on the flexible printed circuit board by the printing method disclosed in the above and other known techniques.

FIG. 2 is a top view of the sheet 5 and shows a state in which the sheet 5 of FIG. 1 is expanded. The sheet 5 has a sheet center part 50 and sheet end parts 51 and 52. A large number of pressure sensors 7 (7a, 7b,...) Are provided on the lattice at the sheet central portion 50. The size of the sheet central portion 50 is substantially the same as the size of the upper surface of the bed (mattress) on which the sheet 5 is laid. Further, groove portions 9 (9a, 9b,...) Are formed in a certain direction (X-axis direction in FIG. 2) on the sheet surface of the sheet center portion 50.
The sheet end portions 51 and 52 are regions on the sheet 5 where the pressure sensor and the groove portion are not formed. The sheet end portions 51 and 52 are located on the side of the bed (mattress) when the sheet 5 is laid on the bed (mattress) (see FIG. 4).

3 is a cross-sectional view taken along the line AA ′ of the sheet 5 in FIG. As shown in FIG. 3, the sheet 5 includes a flexible printed circuit board 5-1 on which the electrode 7-1 is formed and a flexible printed circuit board 5-2 on which the electrode 7-2 is formed. The flexible printed boards 5-1 and 5-2 are formed so as to sandwich the piezoelectric film 6.
Each pressure sensor 7 (7a, 7b,...) Is composed of a pair of electrodes 7-1 and 7-2. An electromotive force is generated by applying pressure to the seat 5, and the pressure can be measured by each pressure sensor 7 (7a, 7b,...). The pressure data measured by each pressure sensor 7 is transmitted to the control terminal 3 and stored in the storage unit 32.

Further, a cover layer 8 is formed on the surface of the sheet 5, and a plurality of grooves 9 (9a, 9b,...) Are formed in the cover layer 8 in a certain direction (X-axis direction in FIG. 2). Has been. Each of the groove portions 9a, 9b,... Is composed of a set of fine groove portions. The fine groove is formed in the cover layer 8 by performing, for example, concave printing.
Thus, by forming the groove portions 9 (9a, 9b,...) On the sheet surface in a certain direction, a sheet structure that is slippery in the direction of the groove portions 9 (X-axis direction in FIG. 2) can be obtained. That is, the caregiver can easily move the patient's body on the sheet 5. On the other hand, the sheet 5 has a property that it is difficult to deviate from the long axis direction (Y-axis direction) of the patient.

In the example of FIG. 3, the plurality of groove portions 9 are formed in the cover layer 8 in a certain direction. It is also possible to ensure slipperiness in a certain direction (X-axis direction in FIG. 2).
Moreover, it is preferable to form the groove 9 at a position that does not overlap the pressure sensor 7 in the horizontal direction so as not to affect how the pressure is applied to the pressure sensor 7. For example, in the example of FIG. 3, the groove 9 is formed between the pressure sensors 7.

Although illustration is omitted, it is preferable that the sheet 5 has a large number of fine holes or slits penetrating each layer of the sheet 5. This prevents the patient from sweating.
2 and 3 show an example of the sheet 5, and the number and arrangement of the pressure sensors 7 and the groove portions 9 are not limited to the examples shown in the drawings.

  FIG. 4 is a diagram illustrating a state in which the posture of the patient is changed using the sheet 5. As shown in FIG. 4A, the sheet 5 is laid on a bed 10 (mattress), for example. Specifically, the sheet 5 is laid so that the sheet end portions 51 and 52 are positioned on the side of the bed 10 so that the sheet central portion 50 is positioned on the upper portion of the bed 10. Then, as shown in FIG. 4B, the caregiver or the like draws the patient's body lying on the back on the seat 5, and rotates the patient's body posture sideways as shown in FIG. 4C. At this time, as described above, the seat 5 has a structure that is easy to slide in the direction perpendicular to the patient's long axis (X-axis direction), so that a caregiver or the like can draw the patient's body with a small force. Moreover, since the sheet | seat 5 can be bent freely, a patient's body can be easily rotated by winding the sheet | seat 5 around a patient.

  FIG. 5 is a diagram illustrating an example of a functional configuration of the posture monitoring apparatus 1 (control terminal 3). The posture monitoring apparatus 1 mainly includes a posture change management unit 11, a posture detection unit 13, a monitoring unit 15, and a notification unit 17. In addition, the posture conversion schedule table 20, the posture template 30, and the posture monitoring information 40 are stored in the storage unit.

The postural change management unit 11 manages a schedule (planned) of the postural change of the patient.
FIG. 6 is a diagram illustrating an example of data contents of the postural change schedule table 20 that holds a postural change schedule (plan). The postural change schedule table 20 holds the postural change scheduled time and the postural scheduled position (scheduled posture) in association with each other. In the example shown in the figure, the body position is “supposed position”, “right-side position”,..., “Left-side position” every two hours, such as “5:30”, “7:30”,. Scheduled to change positions in the order of “rank”.

  The posture change management unit 11 refers to the posture change schedule table 20 and notifies the posture detection unit 13 when the scheduled time for posture change is reached. In consideration of the time required for the caregiver or the like to change the position of the patient, this notification is preferably performed after a predetermined time has elapsed from the scheduled position change time (for example, 10 minutes after the scheduled position change time).

  Further, the posture change management unit 11 refers to the posture change schedule table 20 and, when the scheduled time for posture change (or a predetermined time before the scheduled time) is reached, performs a predetermined notification to a caregiver or the like via the output unit 36. May be. For example, a voice (such as “the time for posture change”) or a voice for instructing a posture change (such as “turn the body up (suppose)”) is output from the speaker. This prevents caregivers from forgetting to change their posture. This notification may be performed via an output unit of an arbitrary information terminal connected to the control terminal 3 via a network. In this way, it is possible to grasp the scheduled time and position of the posture change at a remote information terminal installed in the nurse center or an information terminal held by the patient family.

  When the posture detection unit 13 (including the pressure data acquisition unit 13a and the posture determination unit 13b) receives a notification from the posture conversion management unit 11, the posture detection unit 13 detects the posture of the patient (executes the posture detection process of FIG. 10).

When the pressure data acquisition unit 13 a of the body position detection unit 13 determines that the pressure data effective for body position detection is “acquisable”, the pressure data acquisition unit 13 a starts acquiring pressure data (pressure distribution) from the pressure sensor 7. Here, the case where the pressure data effective for body position detection is “cannot be acquired” is, for example, (1) when the average pressure of the seat 5 (the average value of the pressure of each pressure sensor 7) is smaller than a predetermined threshold ( (2) When the average pressure fluctuation of the seat 5 (the average value of the pressure fluctuation of each pressure sensor 7) is larger than a predetermined threshold (the possibility that the patient is being repositioned is high) If).
That is, the pressure data acquisition unit 13a determines that pressure data effective for body position detection is “acquisable” when the average pressure is larger than a predetermined threshold and the average pressure fluctuation is smaller than the predetermined threshold. Start getting. By such data acquisition control, the pressure data acquisition unit 13a acquires pressure data effective for body position detection.

The body position determination unit 13b of the body position detection unit 13 collates the pressure data (pressure distribution) acquired by the pressure data acquisition unit 13a with the body position template 30, and determines the patient's body position. The posture template 30 is a database that holds pre-measured pressure data (pressure distribution) of each posture of the patient.
FIG. 7 is a diagram illustrating an example of data content of the posture template 30. As shown in the figure, the posture template 30 includes pressure data (“front.dat”) for each posture (“supposed position”, “right-side position”, “left-side position”,... "" Right.dat "," left.dat ",...) Are held in association with each other.

The body position determination unit 13b calculates, for example, the similarity between distributions of the acquired pressure data (pressure distribution) and the pressure data (pressure distribution) of each body position of the body position template 30, and the body position having the highest similarity between the distributions. Is determined as the patient's posture.
The patient's body position determined by the body position determining unit 13b is stored in the body position monitoring information 40 (see FIG. 8) as a body position detection result.

The monitoring unit 15 determines whether or not the patient's posture is normal. Specifically, the patient's body position (detected body position) detected by the body position detection unit 13 is compared with the body position planned in the body position conversion schedule table 20 (scheduled body position), and if the detected body position matches the planned body position. The patient's posture is determined as “normal”, and if they do not match, the patient's posture is determined as “abnormal”.
The determination result (“normal” or “abnormal”) is stored in the body position monitoring information 40 (see FIG. 7).

  FIG. 8 is a diagram illustrating an example of data content of the body position monitoring information 40. As shown in the figure, the time of posture detection (“5:40”, “7:40”,..., “23:40”) and the detected posture (“supposed position”, “right-side position”,... , “Left-side position”) and information on normal / abnormality of the detected body position (“normal”, “abnormal”,..., “Normal”) are stored in association with each other. The posture monitoring information 40 is accumulated in the storage unit 32 as history data with a date. The accumulated posture monitoring information 40 can be displayed and output on the display of the control terminal 3. Further, it can be output to an arbitrary information terminal connected to the control terminal 3 via a network. For example, the history of the posture monitoring information 40 can be confirmed on an information terminal installed in a patient family or an information terminal installed in a nurse center or the like. In this way, both the patient family side and the medical facility side can track the implementation history of the posture change over the past.

  When the monitoring unit 15 determines that the patient's posture is “abnormal”, the notification unit 17 notifies predetermined notification information to a caregiver or the like via the output unit 36 (speaker, display, etc.). For example, a warning sound is output by a speaker, or a voice signal indicating an abnormal posture (“the posture change is different from the schedule” “please check the posture”), or a voice that prompts a normal posture (“the posture is turned upside down) ("Supine position") "" Please position your body in the supine position (supposed position) instead of rightward (right position) "...". In addition, information indicating an abnormal posture or information on a normal posture may be displayed on the display. In addition, the broadcast information may be transmitted to an arbitrary information terminal connected to the control terminal 3 through the network, and the received broadcast information may be output to the output unit of the information terminal. If it does in this way, information information can be checked in the information terminal which a patient family has, the information terminal installed in the nurse center, etc.

  FIG. 8 is a block diagram illustrating an example of the hardware configuration of the control terminal 3. The control terminal 3 can be realized by a general-purpose computer. As shown in the figure, the control terminal 3 mainly includes a control unit 31, a storage unit 32, a media input / output unit 33, a communication control unit 34, an input unit 35, an output unit 36, a peripheral device I / F unit 37, a multi It comprises a channel A / D converter 38 and a bus 39.

The control unit 31 is a central processing unit (CPU).
Unit), ROM (Read Only Memory), RAM (Random Access Memory), and the like. The CPU calls and executes a program stored in the storage unit 32, the ROM, the recording medium, etc. to the work memory area on the RAM, controls each unit connected via the bus 39, and performs all the operations performed by the control terminal 3. Execute the process.

  The ROM is a non-volatile memory and permanently holds a computer boot program, a program such as BIOS, data, and the like. The RAM is a volatile memory, and temporarily holds a program, data, and the like loaded from the storage unit 32, ROM, recording medium, and the like, and includes a work area used by the control unit 31 for performing various processes.

  The storage unit 32 is an HDD (Hard Disk Drive) or the like, and stores a program executed by the control unit 31, data necessary for program execution, an OS (Operating System), and the like. As for the program, a control program corresponding to the OS and an application program for causing a computer to execute processing to be described later are stored. Each of these program codes is read by the control unit 31 as necessary, transferred to the RAM, read by the CPU, and executed as various means.

  The media input / output unit 33 (drive device) inputs / outputs data, for example, media such as a CD drive (-ROM, -R, -RW, etc.), DVD drive (-ROM, -R, -RW, etc.) Has input / output devices.

  The communication control unit 34 includes a communication control device, a communication port, and the like, and is a communication interface that mediates communication between the computer and the network, and performs communication control between other computers via the network. The network may be wired or wireless.

  The input unit 35 includes, for example, a keyboard, a pointing device such as a mouse, and an input device such as a numeric keypad. The measurement conditions (measurement time, measurement range, etc.) of the pressure sensor 7 can be set via the input unit 35.

  The output unit 36 is a sound output device such as a speaker or a display device such as a liquid crystal panel. The display device has a logic circuit or the like (video adapter or the like) for realizing the video function of the computer. The input unit 35 and the display device may be integrally configured like a touch panel display.

  The peripheral device I / F (Interface) unit 37 is a port or an antenna for transmitting and receiving data between the computer and the peripheral device. The computer transmits and receives data to and from the peripheral device via the peripheral device I / F unit 37. I do. The connection form with the peripheral device may be wired (for example, USB (Universal Serial Bus) or the like) or wireless (for example, Bluetooth (registered trademark) or the like).

A multi-channel A / D converter 38 is connected to the peripheral device I / F unit 37. The multi-channel A / D converter 38 is electrically connected to the pressure sensor 7 (7a, 7b,...) Via a wiring (not shown) on the seat 5. Thus, the analog data measured by the pressure sensor 7 (7a, 7b,...) Is converted into digital data via the multi-channel A / D converter 38 and stored in the storage unit 32. When the multi-channel A / D converter 38 receives an instruction to start measurement from the control unit 31, the multi-channel A / D converter 38 starts acquiring measurement data of each sensor of the pressure sensor 7 (7a, 7b,...).
The bus 39 is a path that mediates transmission / reception of control signals, data signals, and the like between the units.

  With reference to the flowchart of FIG. 10, the overall operation of the posture monitoring apparatus 1 (control terminal 3) will be described.

  First, the control unit 31 of the control terminal 3 stands by until the scheduled position change time of the postural change schedule 20 (see FIG. 6) (step S1), and when the planned position change time is reached (step S1; Yes), step The process proceeds to S2, and “position detection processing” is executed. Note that the scheduled time in the posture conversion schedule table 20 and the time (detection time) for performing posture detection need not be the same. The detection time is preferably after a predetermined time elapses from the scheduled position change time (for example, 10 minutes after the planned position change time) in consideration of the time required for the caregiver or the like to change the patient's position.

With reference to the flowchart of FIG. 11, the “posture detection process” in step S2 will be described.
The control unit 31 of the control terminal 3 determines whether or not pressure data effective for body position detection can be acquired (step S21). If it is determined that effective pressure data can be acquired (step S21; Yes), The process proceeds to step S22, and acquisition of pressure data is started. When it is determined that pressure data effective for body position detection cannot be acquired, the control unit waits for acquisition of pressure data until effective pressure data can be acquired. Thereby, pressure data (for example, pressure data during posture change or when the patient is absent) that leads to erroneous detection of the posture is not acquired.

  When the pressure data is acquired, the control unit 31 of the control terminal 3 compares the acquired pressure data (pressure distribution) with the posture template 30 to determine the patient's posture (step S23). The control terminal 3 stores the determined posture of the patient in the posture monitoring information 40 (see FIG. 7) as a posture detection result.

Returning to the flowchart of FIG.
The control unit 31 of the control terminal 3 determines whether or not the patient's posture is normal (step S3). Specifically, the patient's posture (detected posture) detected in step S2 is compared with the posture (planned posture) planned in the posture conversion schedule table 20, and if the detected posture matches the planned posture, the patient's posture is detected. The posture is determined as “normal”, and if it does not match, the patient's posture is determined as “abnormal”. The control terminal 3 stores the determination result (“normal” or “abnormal”) in the body position monitoring information 40 (see FIG. 7).

For example, the detected position at the scheduled time (“5:30”) shown in FIG. 6 and the detection detected at the detection time (“5:40”) shown in FIG. 8 corresponding to the scheduled time. The body positions (= “supposed position”) are the same. In this case (when the planned position matches the detected position), the control unit 31 determines that the patient's position is “normal”.
On the other hand, it was detected at the scheduled position (= “right-side position”) at the scheduled time (“7:30”) shown in FIG. 6 and the detection time (“7:40”) shown in FIG. 8 corresponding to the scheduled time. The detected body position (= “left side position”) does not match. In this case (when the planned posture and the detected posture do not match), the control unit 31 determines that the patient's posture is “abnormal”.

  When it is determined that the patient's posture is “abnormal” (step S2; No), the control unit 31 of the control terminal 3 provides predetermined notification information to the caregiver via the output unit 36 (speaker, display, etc.). Inform the person. For example, a warning sound is output by a speaker, or a voice signal indicating an abnormal posture (“the posture change is different from the schedule” “please check the posture”), or a voice that prompts a normal posture (“the posture is turned upside down) ("Supine position") "" Please position your body in the supine position (supposed position) instead of rightward (right position) "...". Moreover, you may alert | report by displaying the information which conveys the abnormality of a posture on a display, and the information of a normal posture. In addition, the broadcast information may be transmitted to an arbitrary information terminal connected to the control terminal 3 through the network, and the broadcast information may be output to the output unit of the information terminal. If it does in this way, information information can be checked in the information terminal which a patient family has, the information terminal installed in the nurse center, etc.

According to the posture monitoring apparatus 1 described above, the following effects are mainly obtained.
(1) Since the position of the patient is detected using the plurality of pressure sensors 7 provided on the seat 5, it is not necessary to attach a specific device to the patient, and the burden on the patient is reduced.
(2) Since the consistency between the planned posture and the detected posture in the postural change schedule 20 is monitored, it is possible to prevent caregivers' care mistakes and forgetting assistance, and the posture change is performed appropriately.
(3) Since the patient's posture change state is recorded and can be viewed on the control terminal 3 or other information terminals connected to the control terminal 3 through a network, the patient's physiological information can be scientifically confirmed and verified. It is possible to build a safe medical system for both the family and medical institutions.
(4) Since the seat 5 has a mechanism that easily slides in a certain direction, even when the caregiver physically rotates the patient, the patient can be rotated in a certain direction with a small force. This greatly reduces the burden of caregivers and the like.

  In the present embodiment, the posture of the patient is detected using the pressure sensor 7 provided on the seat 5, but the posture detection method is not limited to this example. For example, instead of the pressure sensor 7, a large number of optical sensors may be arranged on the sheet 5, and the patient's posture may be detected based on the intensity distribution of transmitted light that varies depending on the patient's posture, or The patient's posture may be detected by taking a whole image of the patient with an imaging device (monitoring camera) and analyzing the image.

  Further, the time when the posture change is performed (posture change time) may be left as a history. For example, the control terminal 3 detects the timing when the posture has changed by executing the posture detection process periodically (for example, every minute), and stores the time at this time in the storage unit 32 as the posture conversion time. deep. Thereby, it is possible to manage the implementation history of the posture change in detail. At this time, when the posture change time and the scheduled time of the posture change schedule 20 are greatly different (for example, when there is a difference exceeding a predetermined time between the posture change time and the scheduled time), it is desirable to notify the fact. For example, notification information such as “not yet time for posture change” or “the time for posture change is delayed by 30 minutes” is output as voice information or text information.

  Also, as shown in FIG. 12, by providing a monitoring server 200 connected to a plurality of posture monitoring devices 1 (1A, 1B,...) Via a network 100, each posture monitoring device 1A, 1B in the monitoring server 200 is provided. ,... Can be managed in a unified manner. In this case, since it is necessary to know which patient is using which posture monitoring device, the monitoring server 200 identifies the patient ID for identifying each patient and each posture monitoring device 1 (1A, 1B,...). The device ID is set in association with the device ID and stored. Moreover, since the posture conversion schedule differs for each patient, the monitoring server 200 sets and stores the posture conversion schedule table 20 for each patient in association with the patient ID. Then, the monitoring server 200 refers to each patient's postural change schedule table 20 and notifies each postural change apparatus 1 via the network 100 when the scheduled time for postural change is reached. Receiving this notification, each posture monitoring apparatus 1 detects the posture of each patient, and transmits the detected posture (detected posture) to the monitoring server 200. The monitoring server 200 compares the detected posture transmitted from each posture monitoring device 1 with the posture conversion schedule table 20 of each patient, and determines the normality / abnormality of the posture of each patient. When there is a patient whose posture is determined to be abnormal, predetermined notification is performed. For example, information for identifying a patient whose posture is abnormal is displayed on the display of the monitoring server 200. Alternatively, predetermined notification information may be transmitted to the posture monitoring apparatus 1 of the patient whose posture is determined to be abnormal, and the notification information may be output via the output unit of the posture monitoring apparatus 1. Moreover, you may output alerting | reporting information via the output part of the information terminal which the caregiver etc. which were network-connected with the monitoring server 200 or the posture monitoring apparatus 1 (control terminal 3).
