Description

[Detailed description of the invention] (Minute hand for industrial use) The present invention automatically detects when a sick person, elderly person, etc. collapses or crouches due to an abnormal heart or brain attack in the toilet, and takes prompt action. Regarding a toilet sensor for carrying out.

(Prior art and its problems) Restrooms are extremely often the places where sick and elderly people suddenly develop abnormalities, but the toilets are private rooms, and in the event of an abnormality, it may not be possible to make a sound. In most cases, caregivers are unaware of this. In addition,
There are conventional systems in which a call button is installed in the toilet and operated in the event of an abnormality, but this has the disadvantage that the call button cannot be operated in many cases, making it impossible to make a call in the event of an emergency.

However, the urgency of reporting the above-mentioned condition is extremely high considering the medical condition (and the realization of a system that would allow prompt reporting not only by the patient but also by their caregivers has been awaited).

(Means for Solving the Problems) The present invention has been proposed in view of the above points, and its purpose is to provide a toilet sensor that can automatically detect abnormalities in the toilet and promptly report them. Our goal is to provide the following.

In order to achieve the above object, the present invention provides a loop antenna that is disposed at a low position in a toilet and generates electromagnetic induction waves, and a loop antenna that is carried by a person such as a sick or elderly person and enters the area of the loop antenna. The gist of the present invention is a toilet sensor characterized by comprising a transmitter that sends out a predetermined signal radio wave when receiving the electromagnetic induction wave, and a receiver that receives the signal radio wave from the transmitter.

(Function) The present invention focuses on the fact that subjects such as sick people and elderly people always fall down and lie face down or on their backs on the floor during abnormal situations in the toilet.
A loop antenna is placed on the side wall of about 100m in height or housed in a mat on the toilet floor, etc., and the subject is made to carry a pendant-shaped transmitter that transmits a predetermined signal via radio waves when the subject approaches the loop antenna. Since the receiver monitors the signal from the transmitter, abnormalities can be automatically detected.

(Example) DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to drawings showing embodiments.

FIG. 1 shows a configuration diagram of the toilet sensor of the present invention, and 1 indicates a weak radio wave such as VHF when it is carried by a subject such as a sick person or the elderly and receives electromagnetic guided waves such as predetermined long waves. 2 is a loop antenna that is placed in a low position in the toilet and emits electromagnetic induction waves, 3 is a driving Wb circuit that gives a driving signal to the loop antenna, and 4 is transmitted from transmitter l. This is a receiver that receives radio waves and performs notification operations. Note that the transmitter 1 is not limited to a pendant type, but may be a name tag, a bouquet, a belt, a clothing tag, etc. Further, the loop antenna 2 does not need to constantly generate electromagnetic induction waves, and may be linked to an electrolytic switch in a toilet or the like.

FIG. 2 shows the internal configuration of the transmitter 1, which includes a digital code generation circuit 10 that generates a code for identifying a target person, and a digital code generation circuit 10 that generates a VHF high frequency wave and modulates it with the output of a digital code generation port 110. an oscillation/modulation circuit 11 that performs the oscillation/modulation, an amplification circuit 1s12 that amplifies the output of this oscillation/modulation 11 and supplies it to the VHF antenna 13, and an electromagnetic induction antenna 1 that receives the electromagnetic guided waves of the loop antenna 2.

FIG. 3 shows the operation of the present invention, and shows a state in which the subject M has fallen in the toilet 5. In such an abnormal situation, the transmitter 1 hanging around the neck of the subject M is In order to enter the radiation area of electromagnetic guided wave a of loop antenna 2,
By operating the transmitter 1 to transmit VHF radio waves, and having the receiver 4 (see FIG. 1) perform a notification operation when receiving the radio waves, prompt action can be taken.

(Effects of the Invention) As described above, the toilet sensor of the present invention includes a loop antenna that is disposed at a low position in the toilet and generates electromagnetic guided waves, and a loop antenna that is carried by a subject such as a sick person or an elderly person. Since it is equipped with a transmitter that sends out a predetermined signal radio wave when it enters the area of the antenna and receives the electromagnetic guided wave, and a receiver that receives the signal radio wave from this transmitter, abnormalities can be detected immediately. This has the effect of allowing prompt treatment.
