Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device capable of monitoring the occurrence of drowning, in particular to prevent drowning in swimmers or underwater workers.

When humans drown for some reason, they stop breathing.

In many cases, life can be saved if the victim is rescued quickly and given appropriate emergency medical treatment.

In line with this idea, the present invention remotely monitors the breathing status of swimmers or underwater workers, and in the event of a drowning situation, it provides an alert to a third party so that rescue operations can be carried out promptly. The present invention provides a device that does this.

That is, the present invention allows a swimmer or underwater worker to wear a breathing detection ultrasound transmitter that changes the transmission state of ultrasound when the person's breathing reaches a preset state, and the device is placed at a remote location. This ultrasonic receiver receives ultrasonic waves from the respiration detecting ultrasonic transmitter, determines the drowning condition, and issues an alarm.

Hereinafter, the present invention will be explained based on illustrated embodiments.

In the figure, reference numeral 1 denotes an ultrasonic transmitter that is attached to the body of a swimmer or underwater worker, such as the feet, hands, waist, etc., using a pertona.
It consists of a power source 5, which operates to change the ultrasonic transmission state when the breathing of the swimmer or underwater worker reaches a preset state, and 6 is located at a location away from the swimmer or underwater worker. This ultrasonic reception alarm device is composed of an ultrasonic receiver 7, a determination device 8, an alarm device 9 such as a buzzer or siren, and a power source 10, and receives an ultrasonic signal from the ultrasonic transmitter 1. , the nature of the signal is determined by a determiner 8,
When a drowning situation occurs, that is, when the transmission state of ultrasonic waves from the ultrasonic transmitter 1 changes abnormally, the alarm device 9 is operated to generate an alarm.

Note that it is desirable that the ultrasonic transmitter 1 be made as small and lightweight as possible so as not to interfere with the movements of swimmers or underwater workers.

The respiration detector 2 may be of any type as long as it can reliably detect the state of the wearer's breathing. Alternatively, a method such as detecting strain using a strain sensor attached to the belt as described above and outputting an electrical signal according to the detected amount may be used.

The determiner 3 has two functions.

First, it is determined from the output of the breathing detector 2 whether the wearer is breathing normally or whether breathing has stopped or only stopped due to drowning.

For example, a drowning state is determined when no breathing is detected for a set period of time.

Next, for this determination, the plow ultrasonic generator 4 is operated to generate an ultrasonic signal indicating either normal or drowning condition.

The ultrasonic generator 4 generates an ultrasonic signal indicating either a normal state or a drowning state according to instructions from the determiner 3.

Any combination can be used as the normal or drowning state ultrasonic signal, but for example, intermittent transmission with a time interval of tl as a normal signal, intermittent transmission with a time interval of t2 as a drowning state signal, or even simpler In normal conditions, there is no signal (no ultrasonic waves are generated), and in drowning conditions, a continuous oscillation signal may be used.

The power source 5 is a power source for operating the respiration detector 2, the determination device 3, and the ultrasonic generator 4, and can be any general battery or a reserve battery that generates power underwater.

The ultrasonic receiver I is comprised of an ultrasonic underwater microphone, a suitable filter, an amplifier, etc., and receives ultrasonic waves from the ultrasonic transmitter 1, converts them into electrical signals, and amplifies them.

The determiner 8 processes the output from the ultrasonic receiver 7 and determines whether the ultrasonic transmitter 1 is currently emitting a signal indicating that the wearer is normal or is emitting a signal that the wearer is drowning.

The alarm device 9 displays a normal or drowning condition or issues an alarm according to the judgment made by the judgment device 8.

As is clear from the above configuration, when a swimmer or underwater worker wearing the ultrasonic transmitter 1 is in a normal state, the breathing detector 2 detects normal breathing, and the determiner 3 determines that breathing is normal. However, the ultrasonic generator 4 generates an ultrasonic signal indicating that the wearer is normal (or no ultrasonic signal is generated).

On the other hand, if the wearer is drowning, the ultrasonic transmitter 1 will generate an ultrasonic signal indicating the drowning condition.

The ultrasonic reception alarm device 6 receives and judges the above-mentioned ultrasonic signal, and operates the alarm device 9.

As described above, according to the present invention, it is possible to promptly notify a third party of the drowning condition of a swimmer or underwater worker.
By taking appropriate measures based on this, the excellent effect of saving precious human lives can be obtained.

Note that the present invention is not only applicable to a single swimmer or underwater worker, but it is also possible to monitor the drowning state of multiple people by equipping multiple people with ultrasonic transmitters. .
