Description

本発明は、水泳や入浴で溺水した人をいち早く発見、もしくは救護する技術に関するものである。    The present invention relates to a technique for quickly finding or rescuing a person who has drowned during swimming or bathing.

水感知式や手動レバー式の膨張式救命衣は、水泳や入浴時に使用されることは少ないと思われるが、救命用として広く使用されている。水泳や入浴時の溺水発見・救護の技術として多いのは、水圧センサーを用いたものである。水圧センサーを頭部付近に装着し、予め設定した沈水時間により潜水か溺水かを判別し、電波信号を発したり、身に着けた膨張式浮揚具を連動させるもの等がある。    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.

水感知式の膨張式救命衣は、着水に反応して作動してしまう。手動レバー式のみの膨張式救命衣は、入水状態で任意に作動させることができるが、溺水時に意識がある状態で的確な操作を必要とする。水圧センサーを用いたものは、実際の溺水状態を感知するものではないので、設定した沈水時間が短いと潜水か溺水かの判別を誤りやすく、また、設定する沈水時間を長くすると溺水時の発見・救護を遅らせることになる。    Water-sensing inflatable life vests 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 the one using the water pressure sensor does not sense the actual drowning state, if the set submersion time is short, it is easy to judge whether it is diving or drowning, and if the set submersion time is long, the drowning discovery・ It will delay rescue.

本発明の溺水感知器は、実際の溺水状態を感知しようとするものであり、より迅速な溺水者の発見・救護を目的としたものである。    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.

溺水状態になった者は、意識の有無に関わらず、本能的に口を開け呼吸をしようとする。結果、口内には多量の水が流入するが、本発明の溺水感知器はこの水を感知し、周りに知らせ、救護につながるよう構成されている。    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 sensor of the present invention is configured to detect this water, inform the surroundings, and lead to rescue.

感知部は入水時の口内で使用する為、唾液や水しぶき程度では浸水しにくいような容器、例えば穴をあけたカプセルや筒（３）内部に水溶性の係止物（２）を介在させ、ゴムひも（１）の両端をこの係止物（２）につなぐか、その片端ずつを係止物（２）と容器につなぐか、あるいは、容器を分割式にしてその連結点に係止物（２）を設置する場合は、分割部それぞれに両端をつなぐようにしておき、この感知部を口内に含んだうえで、輪になったゴムひも（１）を拡げ、張力を有した状態で頭に被っておくようにする。    Since the sensing part is used in the mouth when entering water, a water-soluble lock (2) is interposed in a container such as a capsule or a tube (3) with a hole, which is difficult to be inundated by saliva or splashing. Either the both ends of the rubber cord (1) are connected to the locking member (2), one end of each is connected to the locking member (2) and the container, or the container is divided and the locking member is connected to the connecting point. When installing (2), connect both ends to each of the divided parts, include this sensing part in the mouth, expand the rubber band (1) that has become a ring, and Put it on your head.

容器の形状が限定されるものではないが、内部の状態を確認するべく透明なものが好ましく、溺水時浸水用穴を確保しておく。唾液や水しぶきは水量的にその水圧が溺水時浸水圧に比べ微弱で、小さな穴であれば浸水しにくいものであるが、多孔質膜や網や弁を取付けておくと、より浸水しにくくなる。これらは、一定の水圧以上で水を通す効果があるので、溺水時浸水圧でのみ通水するようにしておく。容器の壁を多孔状や網目状にしておいてもよい。係止物（２）は、紙やゼラチン、デンプン、砂糖というような水溶性の素材である必要があり、その形状や係止の方法が限定されるものではないが、通常時にゴムひも（１）の輪を拡げても十分に耐えうる強度でありながら、水に浸かると数秒で溶けて破断する程度にしておく。    Although the shape of the container is not limited, it is preferably transparent so as to check the internal state, and a hole for flooding at the time of drowning is secured. The water pressure of saliva and splash is weaker than the flood pressure at the time of drowning, and it is difficult to flood with small holes, but it is more difficult to flood with a porous membrane, net or valve . Since these have the effect of passing water at a certain water pressure or higher, water should be passed only at the flood pressure during drowning. The wall of the container may be porous or meshed. The lock (2) must be a water-soluble material such as paper, gelatin, starch, or sugar, and its shape and locking method are not limited. ) The wire should be strong enough to withstand the expansion of the ring, but will melt and break in a few seconds when immersed in water.

溺水時において、口内に流入する多量の水の水圧下で、容器内部が浸水することにより、係止物（２）が溶けて破断し、ゴムひも（１）の輪が一気に解き放たれるようにする。この際、容器を誤飲しないようゴムひも（１）の両端どちらかには必ず容器が保持されるようにする。分割式容器の場合は両端それぞれに保持されるものである。ゴムひも（１）に浮き（１１）を取付けておけば、水面に浮上して周りに知らせることができる。目立つ色が好ましく、使用者の特定情報を記しておけば有効である。浮き（１１）に取付けた器機により、ブザー音・電波信号（１１ｂ）を連動させても良い。ゴムひも（１）と身に着けた膨張式浮揚具（１２）を連動させることも有効である。    At the time of drowning, when the inside of the container is flooded under the water pressure of a large amount of water flowing into the mouth, the locking member (2) is melted and broken, and the ring of the elastic band (1) is released at a stroke. . At this time, the container is always held at one of both ends of the rubber cord (1) so as not to ingest the container accidentally. In the case of a split type container, it is held at each end. 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 / radio wave signal (11b) may be linked with a device attached to the float (11). It is also effective to link the elastic string (1) with the inflatable levitation device (12) worn.

実際の溺水状態を数秒で感知すると同時に、取付けた浮き（１１）の浮揚や膨張式浮揚具（１２）の連動が始まるので、タイムロスが少なく、迅速な溺水者の発見・救護に期待できる。簡素な物で構成されており、安価である。    At the same time that the actual drowning state is sensed in a few seconds, the floating of the attached 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.

図１は本発明の使用例を示す。輪になったゴムひも（１）が口内から後頭部にかけて巻かれており、浮き（１１）が後頭部に位置するように取付けられている。ゴムひも（１）は、浮き（１１）に防水内蔵されたばね接点（１１ａ）を引き離した状態でつながれており、頭部に巻かれた状態であればその張力を維持できるが、溺水状態になって輪が解き放たれると、たちまちその張力を失い、浮き（１１）が水面に浮上するとともに、ばね接点（１１ａ）が復元され、これに連結された器機により、ブザー音・電波信号（１１ｂ）が発せられる。    FIG. 1 shows an example of use of the present invention. A ring-shaped elastic cord (1) is wound from the mouth to the back of the head, and is attached so that the float (11) is located at the back of the head. The elastic cord (1) is connected to the float (11) in a state where the spring contact (11a), which is waterproof and built-in, is separated. If the elastic cord (1) is wound on the head, its tension can be maintained, but the drowning state occurs. When the ring is released, the tension immediately loses its tension, the float (11) rises to the surface of the water, the spring contact (11a) is restored, and the buzzer sound and radio signal (11b) are generated by the device connected to the spring. Be emitted.

図２は本発明の使用例を示す。輪になったゴムひも（１）が口内から後頭部にかけて巻かれており、首元には膨張式浮揚具（１２）が巻かれている。ゴムひも（１）は、膨張式浮揚具（１２）内部の弁（１２ｄ）を引き上げた状態になるよう、ばね（１２ｃ）およびワイヤー（１２ｂ）でつながれており、これらを包んだゴムチューブ（１２ａ）の先端部にてその接続部が係止されている。頭部に巻かれた状態であればその張力により係止を維持できるが、溺水状態になって輪が解き放たれると、たちまちその張力を失い、ゴムチューブ（１２ａ）内に引き込まれる。それに従って弁（１２ｄ）は開放され、膨張式浮揚具（１２）内に水が流入し、内部の水感知器を作動させることにより、膨張式浮揚具（１２）を連動させる。    FIG. 2 shows an example of use of the present invention. A looped elastic cord (1) is wound from the mouth to the back of the head, and an inflatable float (12) is wound around the neck. The rubber cord (1) is connected by a spring (12c) and a wire (12b) so that the valve (12d) inside the inflatable flotation device (12) is pulled up, and a rubber tube (12a) wrapping these. The connection is locked at the tip of (). If the head is wound around the head, the tension can be used to maintain the lock. However, when the ring is released due to the drowning state, the tension is immediately lost, and the head is pulled into the rubber tube (12a). The valve (12d) is accordingly opened and water flows into the inflatable flotation device (12), activating the internal water sensor, thereby interlocking the inflatable flotation device (12).

図３は本発明の使用例を示す。ゴムひも（１）が輪になるように、その片端は、唾液や水しぶきに濡れないよう筒（３）内部に設置された水溶性の係止物（２）に係止されており、別の片端は、筒（３）内部に留め具（６）で留められている。この筒（３）を口内に含んだ状態で、ゴムひも（１）の輪を頭部に被るようにして装着する。係止物（２）の形状や係止の方法が限定されるものではないが、以下にその実施例を示す。    FIG. 3 shows an example of use of the present invention. One end of the elastic band (1) is engaged with a water-soluble engaging member (2) installed inside the cylinder (3) so as not to be wet by saliva and splashes so that the elastic band (1) forms a loop. One end is fastened inside the cylinder (3) with a fastener (6). With the tube (3) contained in the mouth, the elastic band (1) is attached so as to cover the head. The shape of the locking object (2) and the method of locking are not limited, but examples thereof will be described below.

図４・５・６・７・８・９は本発明実施の一例を示している。ゴムひも（１）の両端はアイスプライス形状で、水溶性の係止物（２）に通すように係止させている。係止物（２）は紙製の筒であり、これを筒（３ａ）のセット穴に両端が少しはみ出るように通し、筒（３ｂ）を筒（３ａ）にはめ込んで、これを挟持させている。筒（３ａ）（３ｂ）の両側にゲート（４）を設置する。ゲート（４）は、耐水性のシートの直径方向に切り目を施し、一定の水圧で開閉する弁であり、唾液や水しぶきの微弱な水圧水を通さず、溺水時浸水圧水のみを通すようにする。これを、多孔質膜や網で代用してもよい。ゲート（４）を押さえ（４ａ）とカバー（５）で、筒（３ａ）（３ｂ）の両側に挟み込む。ゲート（４）に舌や指が接触しないよう、カバー（５）の開口部に目の粗い格子状のガードを施してある。ゴムひも（１）の通し穴は、筒（３ａ）（３ｂ）及びカバー（５）に貫通してあけてあるが、ゴムひも（１）の輪の開放に支障がない程度にきつくして、唾液や水しぶきの浸水を防いでいる。ゴムひも（１）の片端は、輪の開放時に抜けないよう留め具（６）で筒（３ａ）に留められている。感知部の外形は両端に穴のあいたカプセル形状であり、開口部が口の正面向きであるので、溺水吸い込みの水流をストレートに受け、溺水時浸水圧を感知し易くなっている。    FIGS. 4, 5, 6, 7, 8, and 9 show an embodiment of the present invention. Both ends of the rubber cord (1) are ice-price shaped and are locked so as to pass through a water-soluble locking member (2). The locking object (2) is a paper tube, which is passed through the setting hole of the tube (3a) so that both ends slightly protrude, and the tube (3b) is fitted into the tube (3a), and the tube is clamped. I have. Gates (4) are installed on both sides of the tubes (3a) (3b). The gate (4) is a valve that cuts in the diameter direction of the water-resistant sheet and opens and closes at a constant water pressure, so that only weak water of drowning, such as saliva or splashing water, does not flow. I do. This may be replaced by a porous membrane or a net. The gate (4) is sandwiched between both sides of the cylinders (3a) and (3b) by the retainer (4a) and the cover (5). The opening of the cover (5) is provided with a coarse grid-like guard so that the tongue and fingers do not come into contact with the gate (4). The through-hole of the elastic band (1) is drilled through the cylinders (3a) and (3b) and the cover (5), but it is so tight that it does not hinder the opening of the elastic band (1). Prevents saliva and splashes from flooding. One end of the rubber cord (1) is fastened to the cylinder (3a) with a fastener (6) so as not to come off when the ring is opened. The outer shape of the sensing part is a capsule shape with holes at both ends, and the opening is directed toward the front of the mouth. Therefore, the sensing part receives the water flow of the drowning suction straight and can easily sense the drowning pressure during drowning.

図１０・１１・１２・１３・１４・１５・１６は本発明実施の一例を示している。感知部は分割式となっており、筒（３ａ）と筒（３ｂ）の一部をはめ合わせ、その連結部の貫通穴に水溶性の係止物（２）を通し、それらを包むようにカバー（５）をはめ込ませている。係止物（２）は紙圧縮成形された円柱であるが、強度と水溶速度の条件が合えば、他の素材でもよい。筒（３ａ）（３ｂ）内の連結部両側にゲート（４）を設置する。ゲート（４）は、図１３に示すような網状のものであり、唾液や水しぶきの微弱な水圧水を通さず、溺水時浸水圧水のみを通すようにするが、多孔質膜で代用してもよい。押さえ（４ａ）に張りつかせて、外部と接触しないよう筒（３ａ）（３ｂ）内部に押し込んでおく。図１４に示すような薄い耐水性膜による弁で代用する場合は、これを押さえ（４ａ）に接着固定し、前者と同じく筒（３ａ）（３ｂ）内部に押し込んでおく。ゴムひも（１）の両端は、結合された筒（３ａ）（３ｂ）の両端を包むようにはめ込ませるが、溺水時浸水に支障のないよう開口させておく。    FIGS. 10, 11, 12, 13, 14, 15, and 16 show an embodiment of the present invention. The sensing part is of a split type, a part of the tube (3a) and a part of the tube (3b) are fitted, and a water-soluble engaging member (2) is passed through a through hole of the connecting portion, and a cover is wrapped around them. (5) is inserted. The locking member (2) is a cylinder formed by compression molding of paper, but other materials may be used as long as the conditions of strength and water dissolution rate are met. Gates (4) are installed on both sides of the connecting portion in the tubes (3a) and (3b). The gate (4) has a mesh shape as shown in FIG. 13 and does not allow the passage of weak pressure water such as saliva or splashes, but only the flood pressure water at the time of drowning. Is also good. It is stuck to the retainer (4a) and pushed into the cylinders (3a) and (3b) so as not to contact the outside. When a valve made of a thin water-resistant film as shown in FIG. 14 is used as a substitute, the valve is fixed to the retainer (4a) by adhesive, and is pushed into the cylinders (3a) and (3b) like the former. Both ends of the elastic cord (1) are fitted so as to wrap both ends of the connected cylinders (3a) and (3b), but are opened so as not to hinder flooding during drowning.
