DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the preferred embodiments shown in the accompanying drawings. FIG. 1 is a schematic diagram illustrating the structure of an abnormality occurrence detection device according to the present invention, wherein reference numeral 1 denotes a fall detection device carried by an elderly person, a sick person, etc. (hereinafter referred to as a protected person), and 2 denotes a facility such as a hospital or a nursing home. Rooms, corridors,
A receiving device 3, which is disposed in an appropriate place such as a toilet or a plaza, is a centralized monitoring device provided in a facility. The fall detecting device 1 includes a weak radio wave transmitter 6 having an antenna 5 and a fall detecting device 1.
And a vertical / horizontal detection switch 7 that is turned on to activate the weak radio wave transmitter 6 when the protector carrying the device falls down and lays down.

[0008] The receiving device 2 includes a receiver 9 for receiving a weak radio wave transmitted from the weak radio wave transmitter 6 by an antenna 8.
And a telephone line L for transmitting a signal received by the receiver 9 to the centralized monitoring device 3.

The centralized monitoring device 3 is provided in a facility such as a hospital, and includes an alarm device that is activated when the weak radio wave is received.

The fall detecting device 1 has a small, lightweight and portable structure, and is attached in a posture perpendicular to clothes, belts and the like of elderly people by attaching means such as clips, etc., and tilts the body for reasons other than falling. Or an alarm signal is output from the receiver 9 to the centralized monitoring device 3 only when a detection signal is output from the overturn detection device 1 beyond a certain period of time to prevent erroneous detection when the device is lying down for a short time. It may be configured as follows. FIGS. 2 (a) and 2 (b) are views for explaining the configuration of one embodiment of the vertical / horizontal detection switch 7, in which electrodes 11 and 12 are provided at both ends of a sealed container 10, and electrodes 11 and 12 are provided.
A space 13 is filled with a conductive liquid such as mercury or a conductive powdery material (conductive fluid) 14 about 1/3 of the internal volume.

In the vertical position shown in FIG. 1A, since the fluid 14 is biased toward one conductor 12,
Although there is no conduction between 1 and 12, the switch 7 is switched as shown in (b).
In a state in which the electrode 14 is lying down, the fluid 14
The connection between 1 and 12 is made conductive.

The fluid 14 filled in the container 10
The angle at which the switch 7 becomes conductive can be selected to an arbitrary value by variously adjusting the amount of. Therefore,
It is easy to set so that the conduction state does not occur when the body is tilted or swung.

The problem with the use of the vertical / horizontal detection switch 7 is that when the person carrying the protected person lies on a bed or the like in a state other than an abnormal state, the switch 7
Is in a conductive state, which may cause erroneous detection. For this reason, for example, a detecting means such as a piezoelectric sensor is provided on bedding such as a bed or a sofa, and when a wearer uses his own bedding, an alarm is activated by a signal from the piezoelectric sensor. It is preferable to configure so as to prohibit. In the above embodiment, the vertical / horizontal detection switch is used as a sensor for detecting an abnormality of the protected person,
Instead, a means for detecting body temperature / pulse (body temperature / pulse detecting means) may be used, and when the value exceeds a certain value, the weak radio transmitter 6 may be operated. With this configuration, the occurrence of a physical abnormality can be detected and notified promptly regardless of the presence or absence of a fall.

The weak radio wave is used in the apparatus of the above embodiment because of its high practicality, but the scope of the present invention is not limited to this.

As described above, according to the present invention, in a facility such as a hospital or a nursing home, a protected person falls into an abnormal state due to an accident, worsening of a medical condition, or the like, and further operates a button for notifying the occurrence of an emergency. When it is difficult to detect, the sick person or the like can detect that the situation has fallen into the situation and automatically notify the doctor or the like of this situation. When the user falls down or sits on a chair, the operation of the fall detection device is automatically turned off, so that the guardian does not need to operate the fall detection device every time the bedding or the chair is used. Reliability can be improved. Further, regardless of whether or not the person falls, for example, when the protector is lying on the bedding and the body temperature and the pulse show abnormalities, the abnormalities can be detected and an alarm can be generated. The range of response to is greatly expanded, which can contribute to human life protection.
