Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a nurse call device with an automatic emergency warning used when grasping the state of an inpatient or the like in a hospital or the like.
[0002]
[Prior art]
The conventional emergency call system allows an inpatient to carry, for example, a pendant with an emergency call switch, and when the emergency call switch provided on the pendant is operated, the emergency call is wirelessly transmitted. For example, some nurses have a receiver for receiving this emergency call. In this case, the inpatient can inform the nurse of the emergency state by pressing the switch.
[0003]
[Problems to be solved by the invention]
In such a conventional emergency call system, the hospitalized patient himself presses the switch in an emergency, so if the medical condition suddenly deteriorates and the switch cannot be pressed by himself, the emergency situation cannot be reported to the nurse. There was a problem.
[0004]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention sets in advance information that can be worn by a monitoring subject and includes wearing information to the monitoring subject, biological information of the monitoring subject, and preset identification information. A plurality of sensor units that wirelessly transmit at the determined timing, and a reception unit that wirelessly receives transmissions from each sensor unit and issues a warning based on the received information. As a result, even if an emergency situation occurs in the monitored person and an emergency call cannot be made by himself / herself, transmission is performed at the set timing, and the judgment of the emergency situation can be made from the information obtained by receiving this. The result is the same as if an emergency call was made.
[0005]
In addition, the receiving unit receives wirelessly at the transmission timing from each sensor unit, and each of the plurality of sensor units shifts the wireless transmission timing with respect to the wireless transmission timings of the other sensor units. The biological information is stored in the receiving unit when the wirelessly transmitted information cannot be received at a preset timing, when the mounting information indicates non-mounting, and when the mounting information indicates mounting. The warning is given when an abnormal state is indicated. As a result, even if wireless transmission is performed from the plurality of sensor units at the same frequency, they are received without interference, an abnormal state of the monitoring subject is quickly warned, and it is possible to cope with it.
[0006]
Each of the sensor units includes an emergency warning switch, and when the emergency warning switch is operated, the emergency information is transmitted wirelessly. When the emergency information is received, the receiving unit is similar to the above. A warning is about to be made. As a result, an emergency warning can be made by the person being monitored, and an immediate response can be made.
[0007]
Furthermore, the warning by the receiving unit may be by a ringing device and / or a display device.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
[0009]
As shown in FIG. 3, the nurse call device with automatic emergency alert according to the present invention includes a plurality of sensor units 1 and a receiving unit 9 that wirelessly receives transmissions from the sensor units.
[0010]
First, the sensor unit 1 can be attached to a monitoring subject such as an inpatient, and as shown in a perspective view in FIG. 1 and in a block diagram in FIG. 4, a band portion 1a wound in close contact with an arm, An emergency alarm switch 3 connected to a central control circuit CPU2 including an internal clock, a mounting sensor 4 for obtaining mounting information on whether or not the patient or the like as a monitoring subject is mounted, and a pulse of the mounted patient A biological information sensor 5 that detects biological information such as blood pressure and body temperature, and a liquid crystal display device 6 that displays time and other information on a liquid crystal display are provided. In each of the plurality of sensor units, identification information ID unique to each transmitter is set in advance to be distinguished from other sensor units. The information including the above-described mounting information for the monitoring subject, the biological information of the monitoring subject, and the preset identification information is periodically wirelessly transmitted from the transmitter 7 via the antenna 8 at a preset timing. . In addition, each sensor unit 1 has its wireless transmission timing shifted from the transmission timing of other sensor units so that it does not interfere even if it is transmitted at the same frequency.
[0011]
The receiving unit 9 wirelessly receives transmission information from the sensor unit 1. As shown in a perspective view in FIG. 2 and in a block diagram in FIG. 5, transmission information from the antenna 8 in the sensor unit 1 is received by the antenna 10. The information is supplied to the central control circuit CPU12 including the internal clock via the receiver 11, and the supplied information is displayed on the liquid crystal display unit 13 provided on the front surface of the main body 9a. Information such as whether it is transmission, which room it is, whether it is a pulse, whether the patient is not wearing a sensor unit, whether the patient is out of a predetermined range, etc. is displayed on a liquid crystal display. The main body 9a is provided with a sound emitting hole 15 that emits sound from the sounding device 14 such as a buzzer. It is to be noted that the determination as to which patient is transmitted from which hospital room is made by associating the identification information set in advance in the sensor unit 1 with the patient name and the room name.
[0012]
FIG. 3 is a conceptual diagram of the overall configuration. The receiving unit 9 is held on the arm of the nurse 20, and the sensor units 1A, 1B, 1C, 1D, and 1E are attached to the arms of the inpatients 21 to 25. Yes.
[0013]
FIG. 6 is a flowchart mainly explaining the operation of the sensor unit 1. First, the sensor unit 1 and the receiving unit 9 are connected by wire, and the operation is started by turning on the power or operating a reset switch (not shown). Then, initialization (step f1) is performed, and at the time of initialization, the receiving unit 9 gives the current time to each sensor unit 1, and adjusts the time of the internal clock of each sensor unit 1. Also, each sensor unit 1 is given a respective identification information ID. Each sensor unit 1 sets the wireless transmission timing based on the wireless transmission timing set in advance according to the ID. This set time is set at intervals of 5 minutes or 10 minutes for each sensor unit, and with respect to the wireless transmission timing of other sensor units, the times are set differently. To prevent wireless transmission. Then, it is determined whether or not the set transmission time has come (step f2). If the time has come, the presence / absence of sensor unit mounting information and biological information such as a pulse is confirmed (step f3). This information is wirelessly transmitted together with the identification information ID (step f4). If the set time has not been reached, it is determined whether the alarm switch has been operated (step f5). If it has not been operated, the process returns to step f2 again. If it has been operated, emergency information is wirelessly transmitted (step f6). ).
[0014]
FIG. 7 is a flowchart for explaining the operation of the receiving unit 9. When the power unit is started by turning on the power, it is first initialized, and desired settings are made for each sensor unit 1 as described above (step f11). And it is judged whether emergency information was received (step f12). The person to be monitored, that is, the patient, can operate the emergency switch at any time, and in that case, emergency information and identification information are wirelessly transmitted. When receiving it, the receiving unit 9 immediately gives an alarm and a subject display (patient display in this example) on the liquid crystal display unit 13 to give a warning and activate the sounding device 14 from the sound emitting hole 15. A buzzer sound is emitted to give a warning (step f13). This warning continues while the alarm is not released (step f14). If the emergency information is not received in step f12, it is determined whether the scheduled reception time is reached (step f15). The scheduled reception time corresponds to the transmission time set for each of the sensor units described above. When this time is reached, it is determined whether information from the sensor unit 1 is received (step f16). ). At this time, it is determined whether there is any information that should not be received, and if the information is not received, there is an abnormality such that the inpatient is out of the hospital due to going out of the hospital. Since it is estimated, a warning is issued as in the above case (step f13). If the information is received in step f16, the received data is confirmed (step f17), and it is determined whether the mounting information indicates that it is not mounted (step f18). If it is not mounted, the danger is estimated. Therefore, a warning is issued as in the above case (step f14). When the mounting information indicates mounting, it is further determined whether there is an abnormality in the biological information (step f19). If there is an abnormality, a warning is issued in the same manner as described above (step f13), and the alarm is released f14. To finish a series of operations.
[0015]
In addition, the information which issues a warning is not restricted to said example, You may comprise so that a warning may be issued about various information as needed. The timing of wireless transmission may be changed as appropriate according to the number of sensor units and the situation of the monitoring target person. If a dial-type ID setting device is attached to the sensor unit, it is possible to omit a wired connection with the receiving unit when the sensor unit is initialized. Also, when the receiving unit and the person to be monitored (sensor unit) are separated and outside the radio wave reachable range, for example, a receiving unit is placed at the entrance of the hospital room and a centralized display board connected to the receiving unit by wire in the nurse room. You may make it install.
[0016]
【The invention's effect】
As described above, according to the present invention, even when an emergency situation occurs in the monitoring subject and an emergency call cannot be made by itself, transmission is performed at a set timing, and the emergency situation is determined from the received information. The result is the same as if an emergency call was made. If you can report it yourself, you can respond more quickly. By giving the warning by the sounding device or the display device, there is an effect that the notification is surely recognized without being overlooked.
