Description

  The present invention relates to a system for detecting information related to the state of a subject on a bed (eg, a bed bed) and a method for detecting the information.

  For example, a device disclosed in Japanese Patent Application Laid-Open No. 2005-74012 is known as a device for detecting biological information or a bed state of a subject (a sick person, a cared person, an infant, a healthy person, etc.) on a bed portion of a bed. (See Patent Document 1). This apparatus is configured to measure apnea status information as biological information of a subject based on a detection result obtained by detecting movement of a fluid enclosed in a mat of a bed and a bed by a sensor (information detection means). Yes.

  In addition, as this type of device, based on detection results detected by a panel-type sensor (information detection means) placed below the subject on the bed-bed portion, the subject's biological information and occupancy status are detected. An apparatus is known (see, for example, Patent Documents 2 to 4).

  Furthermore, as this type of device, the subject's bed is based on the detection results detected by one or more load detectors (information detection means) arranged between the bed leg and the bed installation surface. An apparatus for detecting a situation is known (see, for example, Patent Documents 5 to 7).

  Such a device generally warns caregivers, nurses, etc. that a subject is in an abnormal state when it is determined that the subject is in an abnormal state based on detection information from a sensor. An abnormality notifying means for notifying by sound is provided.

In such a device, when a caregiver, a nurse, or the like performs a predetermined treatment such as assistance for a subject on the bed sleeping portion, generally, an alarm sound is not emitted before the treatment is performed. In order to do so, a caregiver, a nurse or the like stops the operation of the abnormality notifying means, and then a treatment is performed.
JP-A-2005-74012 JP 2008-178738 A JP 2007-175148 A JP 2006-043445 A JP 2008-264338 A JP 2007-330658 A JP 2006-305343 A

  However, if a caregiver or nurse is busy and forgets to stop the operation of the abnormality notifying means, an alarm sound is generated by an assistance operation or the like by the caregiver or nurse.

  In addition, caregivers, nurses, etc. have stopped the operation of the abnormality notification means before performing the treatment, but after the treatment is completed, the caregivers, nurses, etc. have to resume the operation of the abnormality notification means. If forgotten, the abnormality notifying means does not operate, so that no alarm sound is generated when the subject's condition becomes abnormal.

  Here, since the subject is usually a person who needs assistance, it is difficult for the subject to perform an operation to stop the operation of the abnormality notification means himself, and information on the state of the subject on the bed is detected. This is not desirable for the purpose of this system.

  The present invention has been made in view of the above-described technical background, and an object thereof is to provide an information detection system for a subject on a bed and a bed that can automatically stop or cancel the operation of an abnormality notification unit.

  As shown in FIGS. 1 and 2, the subject information detection system 1 on the bed according to the present embodiment detects information related to the state of the subject 30 on the bed portion 21 of the bed 20, for example, a nurse call. It is integrally incorporated in the device 17. In this embodiment, the bed part 21 of the bed 20 corresponds to the bed of the system according to the present invention.

  The bed 20 is used in medical facilities (eg, hospitals), elderly facilities, nursing homes, accommodation facilities (eg, hotels), general households, etc., such as hospital rooms, examination rooms, examination rooms, guest rooms, bedrooms, etc. Are installed on a bed installation surface 24 consisting of a floor surface.

  The bed 20 has four legs 22, 22, 22, 22 that horizontally support the bed 21 at a predetermined height, that is, a head-side right leg 22, a head-side left leg 22, and a foot-side right. It has a leg 22 and a foot side left leg 22. Further, a rotatable bed moving caster 23 is integrally provided at the lower end of each leg 22. In the present invention, the caster 23 is not necessarily provided at the lower end portion of each leg portion 22.

  On the bed portion 21 of the bed 20, as a subject 30, a sick person, a patient with dementia, an elderly person, a healthy person, an infant, a guest, and the like are in a supine posture (a supine posture) for bedtime, examination, examination, and the like. ) Etc.

  The system 1 of the present embodiment detects the occupancy state of the subject 30 on the bed sleeping portion 21 as information relating to the state of the subject 30. The standing state is, for example, that the subject 30 is on the bed bed 21, the subject 30 lifts the upper body (that is, the subject 30 raises his back), or the subject on the bed bed 21. 30 positions (that is, the position of the center of gravity of the bed bed 21), preparation for getting out of the subject 30 from the bed bed 21, and getting out of the bed 30 of the subject 30.

  In addition, in this invention, the system 1 may detect the biological information etc. of the test subject 30 on the bed bed part 21 as information regarding the state of the test subject 30 in addition. The biometric information is mainly the breathing information, pulse information, body motion information (e.g., turnover frequency) of the subject 30 while sleeping.

  This system 1 includes one or a plurality of load detecting means 3, a controller 4, an abnormality notifying means 10, a detected object 15, and the like.

  The number of load detection means 3 is four in this embodiment. The four load detection means 3, 3, 3, 3 are for detecting loads applied to four parts of the bed bed 21 that are spaced apart from each other. Specifically, as shown in FIG. The load applied to the four leg portions 22, 22, 22, 22 of the portion 21 is detected. One load detecting means 3 is arranged between each leg portion 22 and the bed installation surface 24. Here, for convenience of explanation, the four load detection means 3 are referred to as first to fourth load detection means 3, respectively.

  Each load detection means 3 is basically composed of a load cell, and detects the load applied to each leg portion 22 of the bed bed 21 and provides the detection result (ie, detected load) to each load detection means 3. The data is transmitted to the controller 4 by the communication means (not shown). The communication means is a wireless communication means in this embodiment. In the present invention, the communication means may be a wired communication means.

  As shown in FIG. 3, the controller 4 includes a calculation means 5, a determination means 6, a storage means 7, a detection means 8, a temporary stop means 9, and the like. These means are arranged in the same controller box.

  As shown in FIGS. 1 and 2, the controller 4 (controller box) is disposed in the bed bed 21 or the vicinity thereof. More specifically, the controller 4 (controller box) is disposed in the bed bed 21. More specifically, in the present embodiment, the controller 4 is provided integrally with the call terminal 18 that receives a call request in the nurse call device 17.

  The nurse call device 17 includes a care worker 31 (e.g., a caregiver, a family member of the subject 30 and a relative) who performs assistance, nursing, medical treatment, and the like on the subject 30 and a medical worker (e.g., nurse, doctor). ) And at least one of them. Therefore, the controller 4 is provided with a push button type call switch 18a for calling a care worker 31 or a medical worker.

  The computing means 5 is composed of a computer having a CPU and the like, and computes information on the state of the subject 30 based on the detection results (detected loads) of the four load detecting means 3, 3, 3, 3 It is. Therefore, in this embodiment, the information detection means 2 for detecting information related to the state of the subject 30 on the bed bed 21 includes four load detection means 3, 3, 3, 3 and a calculation means 5. It is.

  Specifically, the calculating means 5 is based on the detected load transmitted from the four load detecting means 3, 3, 3, 3 based on the weight of the subject 30, the position of the center of gravity of the bed bed 21, and the center of gravity thereof. It calculates (determines) the amount of change in position, the back-raising operation of the subject 30, the end sitting position of the subject 30, preparation for getting out of the bed, getting out of the bed, the prediction of falling from the bed bed 21 of the subject 30, and falling.

  That is, in this calculation means 5, for example, the back raising operation of the subject 30 is performed by moving the center of gravity position per unit time when the center of gravity of the bed bed 21 moves from the head side of the bed bed 21 to the foot. When the amount (that is, the moving speed of the center of gravity position) is equal to or greater than a predetermined threshold, it is determined that the subject 30 has raised his / her upper body. The subject 30 is in the end-sitting position, for example, when the center of gravity of the bed bed 21 is the end of the bed bed 21 or when the total load of the four detected loads after the tare processing is the subject 30. Is smaller than the total load when it is located at the center of the bed bed 21 and not more than a predetermined threshold, it is determined that the subject 30 is sitting at the end of the bed bed 21. In addition, in the preparation for getting out of bed, for example, when at least one of the back raising operation of the subject 30 and the end sitting state of the subject 30 is satisfied, it is determined that the subject 30 is preparing for getting out of bed. For example, the fall prediction of the subject 30 from the bed bed 21 is determined to have predicted the fall of the subject 30 from the bed bed 21 when the center of gravity of the bed bed 21 is the end of the bed bed 21. The For example, when the total load after the taring process is equal to or less than a predetermined threshold value close to 0, it is determined that the subject 30 has left the floor or the subject 30 has fallen from the bed bed 21.

  Based on the calculation result (determination result) of the calculation means 5, the determination means 6 determines whether the state of the subject 30 is a predetermined normal state or a state outside the normal state (this is referred to as an abnormal state). Judgment. Specifically, the determination means 6 determines that the state of the subject 30 is abnormal when the calculation result of the calculation means 5 is at least one of bed preparation, bed leaving, fall prediction, and fall. On the other hand, when the calculation result of the calculation means 5 is not any of bed preparation, bed removal, fall prediction, and fall, the test subject 30 is determined to be in the normal state. When it is determined that the state of the subject 30 is abnormal, the determination unit 6 transmits information to that effect, that is, abnormality information to the abnormality notification unit 10. The abnormality information is at least one of the bed preparation information, the bed information, the fall prediction information, and the fall information of the subject 30.

  The storage unit 7 stores the calculation result of the calculation unit 5, the threshold value, the determination result of the determination unit 6, the program necessary for the operation of the system 1, and the like. RAM, ROM, SD (including SDHC) memory card, etc. Consists of.

  The detecting means 8 detects the detected body 15 when the detected body 15 is in a predetermined detection area. In the present embodiment, the predetermined detection area is the area including the bed bed 21, that is, the area formed by the bed bed 21 and the periphery thereof. Specifically, the vicinity of the area around the detection means 8. Specifically, the inside of a predetermined region (for example, a region separated by 0.5 to 3 m) around the detection unit 8 is an area (detection region) in which the detection unit 8 can detect the detection target 15; That is, it is a communicable distance between the detection means 8 and the detection target 15. In the present embodiment, the detection means 8 is arranged in the controller 4 as described above, that is, arranged in the bed bed 21 or the vicinity thereof, and more specifically, arranged in the bed bed 21. .

  The detected object 15 is a wireless IC tag. The detection means 8 is composed of a reader / writer that detects the detected object 15 composed of the wireless IC tag. The configuration of the detection target 15 will be described later.

  The temporary stop means 9 is for temporarily stopping the operation of the abnormality notification means 10, and is a push button type temporary stop switch 9a for temporarily disallowing transmission of abnormality information from the determination means 6 to the abnormality notification means 10. have. That is, when the suspension switch 9a is OFF, the temporary stop means 9 is permitted to transmit abnormality information from the determination means 6 to the abnormality notification means 10, and the operation of the abnormality notification means 10 is allowed. On the other hand, when the temporary stop switch 9a is ON, transmission of abnormality information from the determination means 6 to the abnormality notification means 10 is not permitted, and the abnormality notification means 10 does not operate. This temporary stop switch 9 a is provided in the controller 4.

  Further, the suspension means 9 will be described in detail. The operation of the abnormality notification means 10 is automatically suspended based on the detection result of the detection means 8, or the abnormality notification means 10 based on the detection result of the detection means 8. The pause of the operation is automatically canceled. That is, when the detection means 8 detects the detected object 15, the temporary stop means 9 automatically turns on the temporary stop switch 9a to temporarily stop the operation of the abnormality notification means 10, and then the detection means 8 When the detected object 15 is no longer detected, the temporary stop switch 9a is automatically turned OFF to cancel the temporary stop.

  Furthermore, the temporary stop switch 9a is configured to be able to select either ON or OFF manually.

  The abnormality notification means 10 determines that the condition of the subject 30 is an abnormal state by the determination means 6 and the abnormality information is transmitted to the abnormality notification means 10 from the determination means 6 as the notification target person. This is to notify the care worker 31, medical worker, etc. with sound, light, text, or the like.

  The abnormality notification means 10 includes a notification speaker, a notification lamp, a display unit, and the like. The notification speaker notifies abnormality information with an alarm sound or voice. The notification lamp notifies abnormality information by lighting or blinking the lamp. The display unit notifies abnormality information by displaying characters and drawings, and is composed of a liquid crystal display, an organic EL display, a CRT, and the like.

  This abnormality notification means 10 is installed at a place where care workers and medical workers are packed (eg, a nurse station) or mounted on a mobile phone (including PHS, the same applies hereinafter). In the present embodiment, the abnormality notification means 10 is provided integrally with at least one of the parent device and the child device of the notification terminal 19 that notifies the occurrence of a call request in the nurse call device 17. Reference numeral 11 denotes a signal line for transmitting abnormality information from the determination unit 6 to the abnormality notification unit 10. In this embodiment, transmission of abnormality information from the determination unit 6 to the abnormality notification unit 10 is performed by wired communication, but in the present invention, it may be performed by wireless communication.

  The detected object 15 is composed of a wireless IC tag as described above, and its shape is a card type, a label type, a coin type, a stick type or the like. The wireless IC tag may be of an active type with a built-in power supply (active type) or a passive type with no built-in power supply (passive type).

  Furthermore, the body 15 to be detected is carried by at least one of the care worker 31 and the medical worker for the subject 30 as a person approaching or leaving the bed bed 21. Specifically, the detected body 15 is attached to, for example, clothes of a care worker 31 or a medical worker (see FIGS. 1 and 2), or attached to a part of the body (eg, arm, hand). It can be carried by a caregiver 31 or a health care worker by being hung from the neck or mounted on a portable object carried by the caregiver 31 or a health care worker (eg, a mobile phone or a wristwatch). is there. In FIGS. 1 and 2, the detection target 15 is formed of, for example, a name tag type or card type wireless IC tag, and is detachably attached to the chest of the clothes of a care worker 31 or a medical worker.

  Further, the controller 4 (control box) is provided with a push button type detection start switch 1a for starting and stopping information detection by the system 1. That is, the system 1 starts the information detection by the system 1 by turning on the switch 1a, and the information detection by the system 1 is ended by turning off the switch 1a. Yes.

  Next, operation | movement of the system 1 of this embodiment is demonstrated below.

  FIG. 4 is a flowchart showing the operation of the system 1.

  In step S1 of this flowchart, information detection by the system 1 is started by turning on the detection start switch 1a of the system 1.

  Then, the temporary stop switch 9a of the temporary stop means 9 is automatically turned OFF, and transmission of abnormality information from the determination means 6 to the abnormality notification means 10 is permitted (step S2). Next, in step S3, when the detection unit 8 detects the detected object 15 (in the case of “YES”), the process proceeds to step S4. On the other hand, when the detection means 8 does not detect the detection target 15 (in the case of “NO”), the process returns to step S2. In step S4, the temporary stop switch 9a of the temporary stop means 9 is automatically turned ON, and transmission of abnormality information from the determination means 6 to the abnormality notification means 10 is not permitted.

  In the system 1 that operates according to the flowchart as described above, when information detection by the system 1 is started by turning on the detection start switch of the system 1, the information detection means 2 (that is, each load detection means 3 and calculation means). By 5), the information regarding the state of the subject 30 on the bed bed 21 is detected [information detection step]. As described above, the information regarding the state of the subject 30 includes the weight of the subject 30, the position of the center of gravity of the bed bed 21, the amount of variation in the position of the center of gravity, the back raising operation of the subject 30, the end sitting position of the subject 30, and the preparation for getting out of bed. , Getting out of bed, falling prediction, falling.

  And based on the detection information detected by this information detection process, it is determined by the determination means 6 whether the state of the test subject 30 is an abnormal state [determination process]. As described above, the abnormal state is at least one of the preparation for getting out of bed, getting out of the subject 30, falling prediction, and falling. When it is determined in this determination step that the state of the subject 30 is an abnormal state, transmission of abnormality information from the determination unit 6 to the abnormality notification unit 10 is started. Here, since the temporary stop switch 9 a is OFF, the abnormality information transmitted from the determination unit 6 reaches the abnormality notification unit 10. Then, the abnormality information is notified to the care worker 31 and the health care worker (hereinafter simply referred to as “care worker 31 etc.”) by sound, light, text, etc. by the abnormality notification means 10.

  The care worker 31 or the like who is notified of the abnormality information moves toward the subject 30 (that is, the bed bed portion 21) and approaches the bed bed portion 21 for assistance to the subject 30 or the like. When the detected object 15 carried in advance by the care worker 31 or the like enters the inside of the periphery including the bed bed 21, which is an area where the detecting means 8 can detect the detected object 15. The detection means 8 detects the detection target 15 [detection step]. As a result, the temporary stop switch 9a of the temporary stop unit 9 is automatically turned on, and transmission of abnormality information from the determination unit 6 to the abnormality notification unit 10 is not permitted. As a result, the operation of the abnormality notifying means 10 is temporarily stopped [temporary stopping step].

  In this manner, the care worker 31 or the like performs necessary treatment such as assistance for the subject 30 under the state where the operation of the abnormality notifying unit 10 is temporarily stopped. For example, when the subject 30 is preparing to get out of the bed to go to the toilet or is getting out of bed, the care worker 31 or the like takes the subject 30 to take him to the toilet or assists him / her in a wheelchair. I do. When the subject 30 is about to fall from the bed bed 21, the care worker 31 or the like moves the subject 30 to the center position of the bed bed 21 so that the subject 30 does not fall. I do. At this time, since the operation of the abnormality notifying unit 10 is temporarily stopped, even if a care worker 31 or the like performs a treatment such as assistance on the subject 30, the abnormality information is not notified by the abnormality notifying unit 10. Absent. Therefore, there is no possibility that another care worker 31 or the like rushes to the subject 30 even though the care worker 31 or the like has already rushed to the subject 30.

  When assistance to the subject 30 is completed, the care worker 31 and the like leave the bed bed 21 in order to return to the original place where the care worker 31 and the like were located (for example, a place where the care worker 31 and the like were placed, a nurse station). When the detected object 15 carried in advance by the care worker 31 or the like goes outside the periphery including the bed bed 21 (that is, the detection area of the detecting means 8), the detecting means 8 causes the detected object 15 to move. It will not be detected. As a result, the temporary stop switch 9a of the temporary stop unit 9 is automatically turned OFF, and transmission of abnormality information from the determination unit 6 to the abnormality notification unit 10 is permitted. That is, the operation of the abnormality notification unit 10 is temporarily stopped. Is released [pause release step]. As a result, the system 1 returns to the normal detection mode, that is, normal information detection by the system 1 is performed.

  When the determination unit 6 determines that the state of the subject 30 is normal in the determination step, the detection information detected in the information detection step is stored in the storage unit 7 or adjacent to the abnormality notification unit 10. Displayed on a display means (not shown) such as a liquid crystal display.

  Thus, the system 1 of the present embodiment has the following advantages.

  In the system 1, the detection means 8 is carried by the care worker 31 etc. with respect to the test subject 30, and the detection means 8 detects the to-be-detected body 15 when it exists in a predetermined detection area | region, The temporary stop means 9 is for temporarily stopping the operation of the abnormality notification means 10 based on the detection result of the detection means 8. Therefore, the operation of the abnormality notifying means 10 can be automatically paused according to the behavior of the care worker 31 or the like.

  Furthermore, since the temporary stop means 9 is for temporarily stopping the operation of the abnormality notification means 10 when the detection means 8 detects the detected object 15, the operation of the abnormality notification means 10 is surely paused. Can do.

  Further, the temporary stop means 9 is configured to release the temporary stop 9 when the detection means 8 no longer detects the detected object 15, so that the temporary stop of the operation of the abnormality notification means 10 is ensured. It can be canceled.

  Furthermore, the detection means 8 detects the detected body 15 when the detected body 15 is present around the bed bed portion 21 (bed). Therefore, when the care worker 31 or the like carrying the body 15 to be detected is in the vicinity including the bed bed 21, the operation of the abnormality notifying unit 10 can be surely temporarily stopped. That is, the care worker 31 or the like carrying the body 15 to be detected is notified of the abnormality information by the abnormality notification means 10 and approaches the bed bed 21 for assistance to the subject 30, whereby the detection means 8 is detected. When the detected object 15 is detected, the operation of the abnormality notifying unit 10 is automatically stopped by the temporary stopping unit 9. Therefore, even when the care worker 31 or the like performs necessary treatment such as assistance to the subject 30, the abnormality notification means 10 does not notify the abnormality information. As a result, there is an advantage that there is no possibility that another care worker 31 or the like rushes to the subject 30 even though the care worker 31 or the like has already rushed to the subject 30.

  Furthermore, since the detected object 15 is composed of a wireless IC tag, the detected object 15 can be reliably detected by the detecting means 8, and the detected object 15 can be obtained at low cost.

  Moreover, in this embodiment, even when the care worker 31 or the like performs assistance or assistance of the subject 30 on the bed bed portion 21 during a regular night visit, there is an advantage that abnormal information is not inadvertently notified. is there.

  In the present embodiment, the operation of the system 1 may be performed as follows.

  That is, the care worker 31 or the like temporarily stops the operation of the abnormality notifying unit 10 by manually turning off the temporary stop switch 9a of the temporary stopping unit 9. Then, the care worker 31 and the like provide assistance to the subject 30.

  When assistance to the subject 30 is completed, the care worker 31 and the like are separated from the bed bed 21 in order to return to the original place where the care worker 31 and the like are carried, and are detected by the care worker 31 and the like. When the body 15 goes outside the periphery including the bed bed 21, the detection means 8 does not detect the detected body 15. As a result, the temporary stop switch 9a of the temporary stop unit 9 is automatically turned OFF, and transmission of abnormality information from the determination unit 6 to the abnormality notification unit 10 is permitted. That is, the operation of the abnormality notification unit 10 is temporarily stopped. Is released [pause release step]. As a result, the system 1 returns to the normal detection mode, that is, normal information detection by the system 1 is performed.

  In this case, the temporary stop of the operation of the abnormality notifying means 10 can be automatically canceled according to the behavior of the care worker 31 or the like. Therefore, even when the care worker 31 forgets to turn off the temporary stop switch 9a, the operation of the abnormality notifying means 10 can be resumed.

  Furthermore, since the temporary stop means 9 is designed to release the temporary stop when the detection means 8 does not detect the detected object 15, the temporary stop means 9 reliably releases the temporary stop of the operation of the abnormality notification means 10. Can do.

  Although one embodiment of the present invention has been described above, the present invention is not limited to that shown in the above embodiment, and various modifications can be made.

  For example, in the above embodiment, the bed is the bed bed 21, but in the present invention, for example, a floor surface or a tatami surface on which a mattress is laid may be used.

  Moreover, in this invention, the information detection means to detect the information regarding the state of the subject on the bed may be a biological information detection means for detecting the biological information of the subject. In this case, it is desirable that the biological information detection means includes a panel type sensor or a sheet type sensor that is laid under the subject on the bed, or includes other sensors or calculation means.

  In addition to providing assistance to the subject, the system according to the present invention can be used when a care worker 31 or a medical worker moves toward the bed to perform nursing, medical examination, examination, treatment, or the like. In addition, it may be applied.
