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 discovering or saving a person who has been drowned by 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 inflatable life jackets are thought to be rarely used during swimming and bathing, but are widely used for lifesaving. The most common technique for finding and saving water during swimming and bathing is to use a water pressure sensor. There is one that wears a water pressure sensor near the head, discriminates whether it is diving or submergence according to a preset submergence time, emits a radio wave signal, or interlocks an inflatable floating device worn.

特開2001−184574JP2001-184574 特開2000−155881JP 2000-155881 A 特開平 02−241890JP 02-241890 CN−A−104881958CN-A-104881958 CN−A−104340344CN-A-104340344 US−A1−006129036US-A1-006129036

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 jackets operate in response to landing. An inflatable life jacket with only a manual lever type can be operated arbitrarily in the water-filled state, but requires precise operation in a conscious state during drowning. Those using a water pressure sensor do not sense the actual inundation condition, so if the set submergence time is short, it is easy to make a mistake in determining whether it is diving or submergence.・ Relief will be delayed.

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 of the present invention is intended to detect an actual drowning condition, and is intended to detect and rescue a drowner 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 person who is inundated will instinctively open his mouth and breathe, regardless of consciousness. As a result, although a large amount of water flows into the mouth, the drowning sensor of the present invention is configured to detect this water, inform the surroundings, and lead to relief.

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 unit is used in the mouth at the time of entering water, a container that is difficult to be submerged by saliva or splashing water, such as a capsule with a hole or a tube (3) with a water-soluble locking object (2) interposed, Either connect both ends of the rubber string (1) to the locking object (2), or connect one end of the rubber string (2) to the locking object (2) and the container, or make the container split and lock it at the connecting point. When installing (2), be sure to connect both ends to each of the divided parts, and include this sensing part in the mouth, and then expand the rubber band (1) that has become a ring and have tension. Try to 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, a transparent one is preferable for checking the internal state, and a water immersion hole is secured. Saliva and splashing water is weaker than the inundation pressure in flooding, and it is difficult to submerge if it is a small hole, but it becomes more difficult to submerge if a porous membrane, net or valve is attached. . Since these have the effect of passing water above a certain water pressure, water should be passed only at the submerged pressure. The wall of the container may be porous or meshed. The locking object (2) needs to be a water-soluble material such as paper, gelatin, starch, and sugar, and its shape and locking method are not limited. It is strong enough to withstand even if the ring is expanded), but when it is immersed in water, it melts in a few seconds and breaks.

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。    During flooding, the inside of the container is submerged under the pressure of a large amount of water flowing into the mouth, so that the locking object (2) melts and breaks, and the ring of the rubber string (1) is released at once. . At this time, the container is always held at either end of the elastic band (1) so that the container is not accidentally swallowed. In the case of a split container, it is held at both ends. If the elastic band (1) is attached to the elastic band (1), it can float on the surface of the water and inform the surroundings. A conspicuous color is preferable, and it is effective if specific information of the user is written. The buzzer sound / radio wave signal (11b) may be interlocked by a device attached to the float (11). It is also effective to link the elastic cord (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 flooding condition is sensed in a few seconds, the floating (11) attached and the inflatable float (12) start interlocking, so there is little time loss and it can be expected to find and rescue the watered person quickly. 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 the use of the present invention. A looped rubber string (1) is wound from the mouth to the back of the head and is mounted so that the float (11) is located at the back of the head. The elastic band (1) is connected in a state where the spring contact (11a) incorporated in the float (11) is separated, and the tension can be maintained as long as it is wound around the head. When the wheel is released, it immediately loses its tension, the float (11) rises to the surface of the water, the spring contact (11a) is restored, and the buzzer sound / radio signal (11b) is generated by the equipment connected to it. 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 the use of the present invention. A looped rubber string (1) is wound from the mouth to the back of the head, and an inflatable float (12) is wound around the neck. The rubber string (1) is connected by a spring (12c) and a wire (12b) so that the valve (12d) inside the inflatable buoyancy device (12) is pulled up, and a rubber tube (12a) wrapped therewith. The connecting portion is locked at the tip end portion. If it is wound around the head, the tension can be maintained by the tension. However, when the ring is unwound and the ring is released, the tension is lost immediately and the rubber tube (12a) is drawn. Accordingly, the valve (12d) is opened, water flows into the inflatable buoyancy device (12), and the inflatable levitation device (12) is interlocked by operating the internal water sensor.

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 the use of the present invention. One end of the elastic band (1) is locked to a water-soluble locking object (2) installed inside the cylinder (3) so as not to get wet with saliva or splashes, One end is fastened to the inside of the tube (3) with a fastener (6). With the cylinder (3) included in the mouth, the elastic band (1) is worn so as to cover the head. Although the shape of the latching object (2) and the latching method are not limited, the Example is shown 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。    4, 5, 6, 7, 8, and 9 show an example of the embodiment of the present invention. Both ends of the rubber string (1) are ice-price-shaped and are locked so as to pass through the water-soluble locking object (2). The latching object (2) is a paper cylinder, which is passed through the set hole of the cylinder (3a) so that both ends slightly protrude, and the cylinder (3b) is fitted into the cylinder (3a) to hold it. Yes. 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 the submerged pressure water during drowning is allowed to pass, without passing the weak water of saliva or splashing water. To do. This may be replaced with a porous membrane or a net. The gate (4) is held between the sides of the cylinders (3a) and (3b) with the presser (4a) and the cover (5). A coarse grid-like guard is applied to the opening of the cover (5) so that the tongue (4) does not come into contact with the gate (4). The through hole of the elastic band (1) is drilled through the cylinder (3a) (3b) and the cover (5), but it is tight enough not to interfere with the opening of the elastic band (1). Prevents inundation of saliva and splashes. One end of the elastic band (1) is fastened to the tube (3a) with a fastener (6) so as not to come off when the ring is opened. Since the outer shape of the sensing part is a capsule shape with holes at both ends and the opening is facing the front of the mouth, it is easy to sense the inundation pressure during flooding by directly receiving the water flow sucked in.

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。    10, 11, 12, 13, 14, 15, and 16 show an example of the present invention. The sensing part is divided, and a part of the cylinder (3a) and the cylinder (3b) are fitted, a water-soluble locking object (2) is passed through the through hole of the connecting part, and the cover is wrapped so as to wrap them. (5) is inserted. The locked object (2) is a paper compression-molded cylinder, but other materials may be used as long as the conditions of strength and water-soluble speed are met. Gates (4) are installed on both sides of the connecting portion in the cylinder (3a) (3b). The gate (4) has a net-like shape as shown in FIG. 13, and does not allow the weak water of saliva or splashing water to pass through. Also good. The presser (4a) is stretched and pushed into the cylinder (3a) (3b) so as not to come into contact with the outside. When a valve with a thin water-resistant film as shown in FIG. 14 is used instead, it is bonded and fixed to the presser (4a) and pushed into the cylinders (3a) and (3b) as in the former case. Both ends of the rubber string (1) are fitted so as to wrap both ends of the joined cylinders (3a) and (3b), but are opened so as not to hinder flooding during flooding.
