Abstract
Description
<U>Bouée</U> La présente invention a pour objet une bouée individuelle de sauvetage immergeable. The subject of the present invention is an individual submersible rescue buoy.
Le secteur technique de l'invention est celui des bouées de sauvetage gonflables destinées à la pratique des activités sous- marines, notamment de l'apnée. The technical sector of the invention is that of inflatable lifebuoys for the practice of underwater activities, including apnea.
On connaît actuellement diverses sortes de bouées gonflables. Elles sont toutes mises en oeuvre manuellement. Il n'existe pas sur le marché d'appareil de sauvetage portable et immergeable permettant de gonfler automatiquement une bouée sans intervention volontaire de la victime ou d'un témoin. At present, various types of inflatable buoys are known. They are all implemented manually. There is no portable and submersible rescue device available on the market to automatically inflate a buoy without the voluntary intervention of the victim or a witness.
La présente invention vise à remédier à cet inconvénient. L'objectif a atteindre est une bouée portable utilisable en immersion, particulièrement adaptée aux pratiquants de l'apnée victimes d'un accident de plongée ne leur permettant plus de remonter à la surface par leurs propres moyens. The present invention aims to remedy this disadvantage. The goal is a portable buoy that can be used in immersion, particularly suitable for diving apnea victims who do not allow them to go to the surface again on their own.
Elle s'adresse aux victimes d'accidents nautiques, notamment la noyade syncopale due à une syncope hypoxique. It is intended for victims of nautical accidents, including syncopal drowning due to hypoxic syncope.
Les causes de cet accident sont généralement attribuées au seuil de la pression partielle d'oxygène contenue dans les poumons, qui en dessous d'environ 0.2 bar provoque instantanément la perte de connaissance et la mort par noyade. La baisse de la pression partielle d'oxygène dans les poumons d'un apnéiste est due à la consommation d'oxygène de l'organisme pendant la durée de l'apnée, et à la chute brutale de la pression hydrostatique subie par le pratiquant lors de sa remontée dans la zone des dix mètres. The causes of this accident are usually attributed to the threshold of oxygen partial pressure in the lungs, which below about 0.2 bar instantly causes loss of consciousness and death by drowning. The decrease of the partial pressure of oxygen in the lungs of an apneist is due to the oxygen consumption of the body during the duration of the apnea, and to the sudden fall of the hydrostatic pressure undergone by the practitioner during its rise in the area of ten meters.
Pendant que le sportif consomme son volume d'oxygène à la pression hydrostatique due à la profondeur "une atmosphère tous les dix mètres" la pression partielle est maintenue au dessus de la valeur seuil. Lors de la remontée d'environ trois mètres seconde, la pression diminue brutalement. De ce fait la valeur seuil est atteinte. While the sportsman consumes his oxygen volume at the hydrostatic pressure due to the depth "one atmosphere every ten meters" the partial pressure is kept above the threshold value. During the ascent of about three meters second, the pressure decreases sharply. As a result, the threshold value is reached.
Le froid, la respiration retardée malgré la présence de gaz carbonique dans l'organisme et la fatigue, sont parmi les facteurs aggravants de ce type d'accident. Ainsi au moment de la perte de connaissance le pratiquant est en flottabilité négative, et reste immergé. Au moment du réflexe respiratoire il est victime d'une noyade syncopale. Cold, delayed breathing despite the presence of carbon dioxide in the body and fatigue, are among the aggravating factors of this type of accident. Thus at the moment of loss of consciousness the practitioner is in negative buoyancy, and remains immersed. At the moment of the respiratory reflex he is the victim of a syncopal drowning.
L'objectif de l'invention est atteint par la réalisation d'une bouée selon l'invention, laquelle se caractérise par le fait qu'elle comporte d'une part un harnais recevant sur sa partie dorsale un carénage hydrodynamique qui protège un boîtier étanche de commande au dessous duquel est disposée une réserve d'air comprimé et, d'autre part, sur la partie ventrale du dit harnais est fixée une chambre à air, reliée par une tuyauterie à la dite bouteille, afin de ramener automatiquement en surface un apnéiste en difficulté, puis lui permettre une flottaison aisée, en lui maintenant les voies respiratoires hors de l'eau. The object of the invention is achieved by the embodiment of a buoy according to the invention, which is characterized in that it comprises firstly a harness receiving on its dorsal part a hydrodynamic fairing which protects a waterproof housing a reserve of compressed air and, secondly, on the ventral part of said harness is fixed an air chamber, connected by a pipe to said bottle, to automatically return to the surface a apneist in trouble, then allow him an easy flotation, by keeping him the airways out of the water.
Le boîtier étanche comportant au moins une paroi transparente est doté d'un arbre de transmission et d'au moins un capteur de présence hydraulique qui traversent au moins une de ses parois. Il héberge un accumulateur, un calculateur électronique, un élément moteur électrique rattaché à l'arbre de transmission. The sealed housing having at least one transparent wall is provided with a transmission shaft and at least one hydraulic presence sensor which passes through at least one of its walls. It houses an accumulator, an electronic computer, an electric motor element attached to the drive shaft.
Un accumulateur rechargeable alimente en énergie le calculateur qui, équipé d'un chronomètre programmable manuellement, est raccordé aux capteurs hydrauliques, à l'alerte sonore, et à la commande électrique manoeuvrant l'arbre de transmission. A rechargeable battery supplies energy to the computer which, equipped with a manually programmable stopwatch, is connected to the hydraulic sensors, to the audible warning, and to the electric control that operates the transmission shaft.
Une réserve d'air comprimé ou de gaz est fixée sur son support articulé solidaire du boîtier de commande, puis raccordée par sa robinetterie à l'arbre de transmission. Par une tuyauterie elle est reliée à une chambre à air pourvue d'un clapet de surpression, qui est fixée sur la partie ventrale du dit harnais, à hauteur du sternum. A reserve of compressed air or gas is fixed on its articulated support integral with the control box, then connected by its valve to the drive shaft. By a piping it is connected to an air chamber provided with a pressure relief valve, which is fixed on the ventral part of said harness, at the height of the sternum.
Le pratiquant sélectionne sur le calculateur, la durée maximale de l'apnée qu'il ne souhaite pas dépasser. A l'issue de ce temps écoulé, le calculateur déclenche une alerte sonore qui ne peut être arrêtée que par la mise à l'air libre d'au moins un des capteurs hydrauliques. The practitioner selects on the calculator, the maximum duration of apnea he does not want to exceed. At the end of this elapsed time, the computer triggers an audible alert which can only be stopped by venting at least one of the hydraulic sensors.
Dès le déclenchement de l'alerte sonore le pratiquant dispose d'un délai retour surface qu'il peut lui même programmer, et qui s'il n'est pas respecté, provoque depuis le calculateur le signal de mise en oeuvre de la commande électrique d'ouverture de l'obturateur de la réserve d'air comprimé afin de gonfler la chambre à air pour ramener en surface le pratiquant en difficulté. As soon as the audible warning is triggered, the practitioner has a surface return delay that he can program himself and, if he is not respected, causes the computer to signal the implementation of the electrical command. opening the shutter of the reserve of compressed air to inflate the air chamber to bring to the surface the practitioner in difficulty.
L'avantage de l'invention est une bouée individuelle de sauvetage de conception nouvelle, dont la mise en oeuvre réglable et programmable, la rend particulièrement adaptée à la pratique des activités nautiques et sous-marine, pouvant ramener automatiquement sans intervention du pratiquant ou d'un témoin, la victime d'une syncope en milieu aquatique. - Les capteurs (13) et (14) de présence hydraulique raccordés au calculateur, sont réalisés à l'aide d'un matériau bon conducteur d'électricité et utilisent l'élément liquide pour établir le contact entre eux afin de déclencher le départ du chronomètre dès l'immersion du pratiquant. The advantage of the invention is a new life-saving rescue buoy, the implementation of which is adjustable and programmable, makes it particularly suitable for practicing nautical and underwater activities, and which can be automatically brought back without the intervention of the practitioner or the child. 'a witness, the victim of a syncope in an aquatic environment. - The sensors (13) and (14) of hydraulic presence connected to the computer, are made using a good electrically conductive material and use the liquid element to establish contact between them to trigger the departure of the time after immersion of the practitioner.
