Description

  The present invention relates to a sensor for identifying a person that identifies a nurse's behavior and informs the nurse or the like at home or a nursing facility.

  Nursing of a patient at home or a nursing facility needs to grasp the behavior of the patient for a long time. In particular, it is important for nurses to be aware of getting out of bed and haiku from bedclothes as a behavior to be aware of immediately, but nursing for a long time is very mental and physical for the nurse. It is a big burden. Therefore, various care support devices have been proposed to reduce these.

  For example, the present applicant can use a load detection sensor (refer to Patent Document 1), a cordless load detection sensor (refer to Patent Document 2), and a person from a bedding as a bed leaving sensor to be installed around a patient at home or in a care facility. The identification device (refer patent document 3) which identifies having left the floor, the pillow sensor (refer patent document 4), the toilet sensor (refer patent document 5), etc. are developed. Various wrinkle monitoring systems using a transmitter having an RFID function have been disclosed (see Patent Documents 6, 7, and 8).

Utility Model Registration No. 3170396 Patent Registration No. 4414465 Utility Model Registration No. 3166882 Utility Model Registration No. 3144892 Utility Model Registration No. 3171488 JP 2002-319083 A JP 2006-285520 A Japanese Patent Application Laid-Open No. 10-143772

  The bed sensor developed by the present applicant uses a load detection sensor, and when a person steps on the bed sensor, a contact signal is sent from the transmitter built in the bed sensor, which is received by the receiver. A detection signal is output. With this detection signal, it is possible to notify an alarm or the like that a person has stepped on the floor sensor. However, this bed sensor transmits a contact signal even when a person other than the nurse (for example, a nurse or a visitor) steps on the sensor, so that the nurse and the person other than the nurse are identified. It was difficult.

  On the other hand, the wrinkle prevention system of Patent Document 6 is a device in which a transmitter with an IC tag is attached to a shoe, so that other footwear without an IC tag or a patient with dementia who has left a room with bare feet are detected. There was a problem that I could not. Moreover, the eyelid monitoring device of Patent Document 7 generates a control signal by generating a signal received by two or more receivers of an action pattern in the living room of the person to be monitored. It is different from the idea. Furthermore, in the monitoring system of Patent Document 8, a weak radio wave leaking coaxial cable is laid at the boundary of a specific area to be monitored, and the monitored person only receives the radio wave when the receiver of the mobile device receives this radio wave. This is a notification of approaching the vicinity, and the leaky coaxial cable has to be laid all around the monitored area, which is troublesome.

  Products that are identified by attaching an IC chip (IC tag) called RFID to a person have already been put into practical use, and are used as products in ski resorts, rental shops, mass retailers, and the like. However, when this product is used in a medical facility such as a hospital or an elderly care facility, RFID uses an electromagnetic wave that is very strong for excitation, which adversely affects medical devices and pacemakers.

  Usually, an RFID does not have a power source such as a battery, but receives power transmission (excitation electromagnetic wave = strong electromagnetic wave) from a transmitter / receiver to excite a coil in the RFID to generate an electromotive force. It is configured to operate and transmit an ID signal. This ID signal is received and identified by the receiver. The RFID having such a configuration needs to output a strong electromagnetic wave for exciting the coil. If this is used, there is a problem in that it cannot be used because it adversely affects medical devices and cardiac pacemakers in a medical environment. is there.

  The present invention has been made to solve these problems. By combining a bed sensor and a transmitter comprising an ID chip incorporating a transmitter circuit and a battery, a person wearing the transmitter (covered) is provided. It is an object to provide a sensor for identifying a person who identifies (nurse) and informs a nurse or the like.

  In the present invention, a sensor for identifying a person does not mean a single sensor, but is defined as a device that identifies a specific person with a sensor. The principle of the sensor for identifying a person of the present invention is as follows.

  As shown in FIG. 1A, a transmitter that transmits a thin, very small and weak radio signal continuously or intermittently and a receiver that receives the signal of the transmitter are installed. The transmitter and the receiver can communicate with each other within a range of approximately 3 m. For example, at a distance of 3 m or less from the transmitter, the receiver can always receive a weak radio signal from the transmitter, and the receiver outputs an output signal indicating that it is receiving. On the other hand, as shown in FIG. 1B, when the transmitter and the receiver cannot communicate with each other, for example, when the transmitter and the receiver are separated by 3 m or more, the receiver cannot receive the signal from the transmitter. No output signal is output from the receiver. Note that how many meters the communicable distance between the transmitter and the receiver is set is a design matter of the applicant.

  If this transmitter is attached to the body part of the nurse, it can be identified whether the person who stepped on the bed sensor is the nurse or another person (for example, a nurse or a visitor). If this principle is applied, the presence or absence of an output signal from the receiver when the patient wearing the transmitter approaches within a predetermined distance from the receiver, or when the transmitter is separated from the receiver by a predetermined distance or more. Can be designed to detect A sensor for identifying a person that identifies the patient wearing the transmitter using the presence or absence of the output signal can be produced.

And when the said 1st receiver and the 2nd receiver output a detection signal in the same time slot | zone, the control part which transmits the control signal containing ID information is provided.

  If comprised in this way, a detection signal will be transmitted from a 2nd receiver, if the nursing person equipped with the transmitter steps on a bed sensor. On the other hand, since the first receiver and the bed leaving sensor are installed at a communicable distance (for example, within 3 m), the distance between the transmitter and the first receiver is also a communicable distance, and the detection signal is the first. Sent from the receiver. When the first receiver and the second receiver output a detection signal in the same time zone, the control unit transmits a control signal including ID information to a notification device or the like. As a result, the nurse or the like can immediately grasp the behavior of the nurse wearing the transmitter, such as getting out of bed or wrinkle.

  According to a second aspect of the present invention, there is provided a sensor for identifying a person, a transmitter mounted on a person that continuously or intermittently transmits a weak radio signal by an ID chip incorporating a transmission circuit and a battery, and the transmission A first receiver is disposed in which the detection signal is interrupted when the device is separated by a predetermined distance or more, and a control unit is provided that transmits a control signal including ID information when the detection signal of the first receiver is interrupted. It is characterized by having.

  If comprised in this way, the detection signal from a 1st receiver to a control part will be interrupted, if the care recipient who equipped with the transmitter is separated from the 1st receiver 3 m or more. The control unit transmits a control signal including ID information to a notification device or the like based on the interruption of the detection signal from the first receiver. As a result, the nurse or the like can immediately grasp the behavior of the nurse wearing the transmitter, such as getting out of bed or wrinkle.

  A sensor for identifying a person according to claim 3 of the present invention is characterized in that a plurality of the first receivers are provided. For example, if the first receiver is installed in the bed, under the bed, pillow, living room entrance, under the stairs, in front of the elevator, front door, toilet, entrance, etc. It is possible to immediately grasp the behavior of the nursing staff wearing the.

  In the sensor for identifying a person according to claim 4 of the present invention, at least one of the first receiver, the second receiver, and the control unit is incorporated in a console that transmits and controls a signal to a terminal device. It is characterized by that. If configured in this way, it can be applied to nurse call systems using consoles, cable-type and cordless bed sensor devices, pillow sensor devices, toilet sensor devices, etc. It is possible to immediately grasp the behavior of the nurse.

  The sensor for identifying a person of the present invention is a nursing care device equipped with a transmitter by wearing a transmitter that continuously or intermittently transmits a weak radio signal with an ID chip incorporating a transmission circuit and a battery. Since only a person can be identified and a control signal including ID information can be notified to an alarm device, etc., this can be reported to the nurse's bed, under the bed, pillow, room entrance / exit, under the stairs, in front of the elevator, on the front door, If it is installed in the bed, under the bed, in the entrance / exit of the toilet, the entrance / exit of the elevator, the toilet, the doorway, or under the stairs, the nurse can immediately grasp the behavior of the patient identified by the ID information. .
