Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a hospital bed alarm device, and particularly relates to a hospital bed alarm device that automatically issues an alarm in the event of a fall of a patient from a hospital bed, an accident at night, etc. .

[Technical Background of the Invention] Traditionally, hospitals etc. have used nurse calls and calls as shown in Figure 3.
An intercom system is used for communication between caregivers and nurses. The nurse call/intercom system shown in this example includes an interbon slave unit 1, a nurse call/intercom system parent unit 4! ! 2', an interface 3'', an intercom transmission line 4', and an indicator light 23.
Nurse call intercom system via parent 8N
2', and can make calls and talk to each other.

[Problems with the Background Art] As is clear from the above configuration, in the conventional nurse call intercom system, it is assumed that the call operation is performed by the patient's own will, and there is a possibility that the patient may fall from the hospital bed or In some cases, it may be difficult or impossible to contact patients of their own will, such as when they leave their hospital beds at night, and the hospital setting is insufficient.

[Purpose of the Invention] The present invention was devised to improve the above-mentioned inconvenience, and when a patient is absent for a certain period of time, an alarm is automatically issued assuming the possibility of an accident. It is an object of the present invention to provide a highly reliable hospital bed 1f13 device that informs whether a patient is absent.

[Summary of the Invention] In order to achieve the above object, the hospital bed alarm device according to the present invention includes a base unit installed at a nurse's station, and a slave unit connected to the base unit via a transmission line and installed in a patient room. A nurse call/intercom system consisting of a sensor for detecting the absence of a patient, a timer connected to the sensor and measuring the time of the patient's absence, and an alarm means controlled by the timer and generating a signal sound. If the patient is absent for a configured and preset period of time, an alarm will be automatically issued.

[Embodiments of the Invention] Preferred embodiments of the present invention will be described below with reference to the drawings.

111 Example 2 First, the appearance will be explained with reference to FIG. The nurse call intercom system of the first embodiment includes an intercom child 11 (hereinafter referred to as child ja1) and a nurse call intercom system parent 6m2 (hereinafter referred to as 11 machine 2).
, an interface 3, an intercom transmission line t1, a switch 22 for controlling a timer, an indicator light 23, and a pressure sensor 5 as a sensor. Next, the circuit and connection relationship will be described with reference to FIG.

The handset 1 is composed of a telephone system 12 and a call switch 11.

The host 12 includes an interface section 21, a switch 22 for controlling a timer, an indicator light 23, a telephone communication system 24, an alarm 211 as an alarm means, and a calling means 212.

The interface 3 includes an interface section 31, a switch 311, a chattering prevention circuit 312, and a timer 31.
3. Consists of one-shot multi-by-break 314 and relay 315.

The telephone call system 12 in the handset 1 is connected to the interface section 31 in the interface 3, and the call switch 1 is connected to the interface section 31 in the interface 3 as well.

The pressure sensor 5 is connected to the switch 311 of the interface 3.
The chattering prevention circuit 312 and the timer 313 are connected in this order. The timer 313 is connected to the interface 3 via a one-shot multivibrator 314 and a relay 315, and directly to the interface 3. Note that the switch 22 of the base unit 2 is set to “O”.
N'', power is supplied to the timer 313 via the interface unit 21 and the interface M3, and is also sent to the chattering prevention circuit 312 and the one-shot multivibrator 314.
3 and the calling means 212 are connected in series to the calling system 24.1.
The flilli devices 211 are directly connected to respective corresponding parts of the interface section 21.

Corresponding parts of the interface section 31 in the interface 3 and the interface section 21 in the base unit 2 are connected via the intercom transmission line 4, as shown in FIG.

The operation of the nurse call/intercom system of this embodiment will be explained below.

The slave device 1 can call and talk to the base device 2 via the interface section 31, the intercom transmission line 4, and the interface section 21. The operation sequence etc. are exactly the same as the conventional one. Next, to show the operation of the hospital bed alarm device, first, switch 311 and switch 22
is "ON", that is, when the alarm system is activated, the moment the patient leaves the bed, the change in the output of the pressure sensor 5 is waveformed into a pulse by the chattering prevention circuit 312, and starts the timer 313. .

When a preset certain period of time has elapsed, the timer 313 outputs a trigger, and the one-shot multivibrator
Start up 314. One shot multi vibrator
314 serves to maintain a constant pulse width on the intercom transmission line 4 via the relay 315. This signal is on intercom transmission line 4, PJ! The W alarm 211 is made to sound via the interface section 21 in the L2. In other words, since the patient will be absent for a certain period of time, the possibility of an accident is assumed and communicated to the #guardian. Since the lamp of the corresponding patient in the indicator light 23 is turned off, the nurse can look at the indicator light 23 and recognize which patient the abnormal situation has occurred to, allowing prompt treatment.

Although this embodiment shows a case where the hospital bed tensioning device is built into the nurse call/intercom system, it is also possible to install the hospital bed tensioning device independently.

1 and 1 Tsuji 2 The main difference in configuration from Embodiment 1 is the interface 3.
The connection point from the internal relay 315 to the interface section 31 is the point (a).

(Example 1 is connected to (1)). ) The operation of the intercom, the sensor, and the timer are the same as in the first embodiment. However, in the first embodiment, when the patient is absent, the signal is sent to the transmitter 2 in the main unit 2 by an independent system.
However, in this embodiment, it is carried on the transmission line for normal calls, so it is not possible to distinguish between intercom calls and signals from the sensor from tJl.
This has the advantage of a simpler circuit configuration.

[Effect of the invention] As is clear from the above examples, according to the present invention,
When a patient falls from a hospital bed or has an accident at night, sensors installed in the hospital bed will detect this, and when a certain period of time has elapsed, an alarm will be issued and a display will be displayed indicating which patient is in an abnormal situation. It has become possible to provide a highly reliable hospital bed alarm system that can respond quickly.
