Abstract

To provide a drowning sensor for detecting an actual drowning condition for a purpose of detecting and rescuing a drowning person quickly.SOLUTION: Both ends 1a and 1b of a rubber band 1 are fastened with a water-soluble material, for example, a piece of paper 2, and are covered with a capsule 3 having holes at both ends so that the piece of paper does not get wet with saliva and splashes; and while the capsule is put in a mouth of a person, the rubber band is put around a head of the person. When drowning, a large amount of water flowing into the mouth is flooded into the capsule, the piece of paper melts and breaks, and thus, since the rubber band is released at a stretch, a float is attached to the rubber band in advance, and the float can be floated on a surface of water to inform the surroundings, alternatively, an inflatable flotation device may be connected in advance so as to respond to a presence or absence of tension of the rubber band, and may be interlocked.SELECTED DRAWING: Figure 3

Description

    The present invention relates to a technique for quickly finding or rescuing a person who has drowned during swimming or bathing.

    Water-sensing and manual lever-type inflatable life jackets are rarely used for swimming or bathing, but are widely used for life saving. A common technique for finding and rescuing drowning during swimming and bathing is to use a water pressure sensor. There is a type in which a water pressure sensor is mounted near the head, determines whether diving or drowning based on a preset submersion time, emits a radio signal, or interlocks with an inflatable floating device worn.

    Water-sensing inflatable life jackets operate in response to water landing. The inflatable life vest with only the manual lever type can be operated arbitrarily in the state of water entry, but requires an accurate operation while being conscious when drowning. Since there is nothing to detect the actual drowning state using a water pressure sensor, if the set submersion time is short, it is easy to make a mistake in diving or drowning, and if the set submersion time is long, the drowning discovery・ It will delay rescue.

    The drowning sensor according to the present invention is intended to detect an actual drowning state, and is intended to find and rescue drowners more quickly.

    A drowned person instinctively opens his mouth and tries to breathe, regardless of consciousness. As a result, a large amount of water flows into the mouth, and the drowning detector of the present invention is configured to detect this water, inform the surroundings, and lead to rescue.

    The ends (1a) and (1b) of the elastic band (1) are fastened by a water-soluble material, for example, a piece of paper (2) so as to form a loop, and holes are formed at both ends so as not to get wet with saliva and splashes. It is covered with a capsule (3) having an open end, and with the capsule (3) contained in the mouth, the ring of the elastic cord (1) is worn over the head.

    Although the shape and locking method of the paper piece (2) are not limited, it is preferable that the paper piece (2) melts and breaks in a few seconds when immersed in water, while having strength enough to withstand normal expansion of the ring. Through holes (3d) or air holes (3e) of the elastic cord (1) are arranged near both ends of the capsule (3) to secure a minimum air release required for inflow of water at the time of drowning. Saliva is usually located on the back of the tongue along the oral cavity wall, but combing (3c) in the capsule (3) to reduce the risk of a small amount of saliva or splashes flooding and wetting the paper (2). It may be like a double wall. Also, the capsule (3) is convenient for setting the paper piece (2) in a half-split type, and it is preferable that the capsule (3) is transparent to check the internal state. To prevent accidental ingestion during use, both ends of the rubber cord (1) are used. (1a) or (1b) Be sure to be locked to either.

The inside of the capsule (3) is flooded by a large amount of water flowing into the mouth at the time of drowning, and the piece of paper (2) is melted and broken, whereby the rubber cord (1) is released at a stretch.
If the float (11) is attached to the rubber cord (1), it can float to the surface of the water and notify the surroundings. A conspicuous color is preferable, and it is effective if specific information of the user is described. The buzzer sound and the radio signal (11b) may be linked. It is also effective to link the elastic string (1) with the inflatable levitation device (12) worn.

    At the same time as detecting the actual drowning state in a few seconds, the floating of the mounted float (11) and the interlocking of the inflatable float (12) start, so that time loss is small, and rapid detection and rescue of drowners can be expected. It is composed of simple things and is inexpensive.
