La présente invention est relative à une cartouche à vide, réarmable, caractérisée en ce qu'elle se compose de deux èléments complémentaires, l'un de l'autre : Une cartouche réarmable susceptible de générer et contenir temporairement le vide ; un embout qui, accouplé à la cartouche, provoque la détente du vide précédemment généré et contenu. The present invention relates to a resettable vacuum cartridge, characterized in that it consists of two complementary elements, one from the other: A resettable cartridge capable of generating and temporarily containing the vacuum; a nozzle which, coupled to the cartridge, causes the previously generated and contained vacuum to relax.
Les sources de vide, plus ou moins poussé, portatives et manuelles, ont fait l'objet de nombreuses recherches et brevets, portant moins sur les pompes que sur leurs périphériques et/ou accessoires d'exploitation de ce vide. The sources of vacuum, more or less high, portable and manual, have been the subject of numerous researches and patents, relating less to the pumps than to their peripherals and / or accessories for exploiting this vacuum.
Presque toutes sont basées sur le déplacement, mécaniquement forcé, d'un piston dans un cylindre dit : "Corps de pompe". Au cours de ce déplacement, le piston réalise un volume de vide égal à sa surface que multiplie sa course. Almost all are based on the mechanically forced displacement of a piston in a cylinder known as: "Pump body". During this movement, the piston achieves a vacuum volume equal to its surface that multiplies its stroke.
Parmi les très nombreuses applications du vide "manuel", il faut citer celles au secours de la santé. Il faut noter, actuellement, un regain d'intérêt médical pour la succion, sous haute dépression, appliquée aux blessures qu'infligent certains animaux particulièrement vulnérants, (insectes, poissons, reptiles etc) qui, par piqûres pu morsures injectent leur venin dans le but de se défendre ou de chasser. Among the very many applications of "manual" vacuum, we must cite those for health relief. It should be noted, currently, a renewed medical interest in suction, under high depression, applied to wounds inflicted by certain particularly annoying animals (insects, fish, reptiles etc.) which, through bites or bites inject their venom into the aim of defending or hunting.
Certains appareils existants réalisent efficacement cette succion ils sont généralement d'un coût élevé pour être efficaces, ce qui les mets hors de portée du pouvoir d'achat des populations qui en auraient le plus l'usage, (habitants de la ceinture intertropicale, en particulier). Certain existing devices effectively carry out this suction; they are generally of a high cost to be effective, which puts them beyond the reach of the purchasing power of the populations which would have the most use of them (inhabitants of the intertropical belt, in particular).
La présente invention a pour objet de décrire les techniques et moyens utiles à la réalisation d'un appareil original et économique, capable de réaliser des vides importants applicables, à travers une ventouse, aux plaies envenimées ; ce, sans exclusive d'application. The object of the present invention is to describe the techniques and means useful for producing an original and economical device capable of producing large voids applicable, through a suction cup, to poisonous wounds; this, without exclusive application.
Les dessins, figures 1, 2 et 3, représentent la cartouche à vide, réarmable, et illustrent la technique et les moyens nécessaires à son fonctionnement. La figure 4 représente les dispositifs permettant de détendre, contenir et utiliser (à l'aide d'une ventouse, par exemple et sans exclusive) le vide matérialisé dans la cartouche précédemment décrite. The drawings, FIGS. 1, 2 and 3 represent the resettable vacuum cartridge and illustrate the technique and the means necessary for its operation. FIG. 4 represents the devices making it possible to relax, contain and use (using a suction cup, for example and without limitation) the vacuum materialized in the cartridge described above.

Fonctionnement : Avec -ou sans accouplement de la ventouse (13) à la "cartouche à vide", la remontée, suivie du verrouillage en position haute du piston (2) (armement) réalise un vide important dans l'ensemble des volumes représentés par 1, 7 et 11. -La surface creuse de (8) est soumise à la pression atmosphérique, ce qui a pour effet de renforcer l'appui de contact entre (8) et (9') et d'accroître l'étanchéité entre ces deux éléments. La cartouche à vide est alors prête à l'emploi. Operation: With -or without coupling of the suction cup (13) to the "vacuum cartridge", the ascent, followed by locking in the high position of the piston (2) (cocking) creates a large vacuum in all of the volumes represented by 1, 7 and 11. -The hollow surface of (8) is subjected to atmospheric pressure, which has the effect of strengthening the contact support between (8) and (9 ') and increasing the seal between these two elements. The vacuum cartridge is then ready for use.
Il suffit de connecter la ventouse (13) par sa-partie cylindrique (13') et de l'enfoncer plus avant pour que "Cartouche" et "Ventouse" assemblées constutuent une "Unité Opérationnelle" d'application instantannée de vide à usage médical anti-venin. It is enough to connect the suction cup (13) by its cylindrical part (13 ') and to push it further forward so that "Cartridge" and "Suction cup" assembled constitute a "Operational Unit" of instantaneous application of vacuum for medical use anti-venom.
Durant cette opération, la ventouse appliquée fortement, par pression selon l'axe du corps de pompe (1) sur l'épiderme, à ltendroit d'une blessure envenimée, s'enfonce dans l'alésage (9") jusqu'à venir appuyer sur le centre du joint (8), l'obligeant à décoller du siège de clapet (9'). During this operation, the suction cup applied strongly, by pressure along the axis of the pump body (1) on the epidermis, at the location of a poisoned wound, sinks into the bore (9 ") until it comes press on the center of the seal (8), forcing it to take off from the valve seat (9 ').
Cette action a pour effet de mettre en communication le volume de Vide contenu par le corps de pompe (1) associé aux volumes (7 et 11) avec le volume d'air contenu par l'enceinte que constitue la ventouse (13), fermée à sa base par la surface épidermique à traiter. La présence d'une, ou plusieurs encoches (16) a permis, au cours de l'action précitée, le passage du vide entre les deux éléments "Cartouche-Ventouse" et d'équilibrer leurs pressions initiales. This action has the effect of bringing the volume of Vacuum contained by the pump body (1) associated with the volumes (7 and 11) into communication with the volume of air contained by the enclosure constituted by the closed suction cup (13). at its base by the epidermal surface to be treated. The presence of one or more notches (16) has allowed, during the aforementioned action, the passage of the vacuum between the two elements "Cartouche-Suction cup" and to balance their initial pressures.
Il est alors possible de désaccoupler la cartouche de la ventouse dans le but, par exemple, d'ajouter une nouvelle "dose de vide" à l'intérieur de la ventouse, ou de mettre sous pansement dépressurisé la zone épidermique envenimée durant le transport du blessé vers un Centre Hospitalier. Dans ce cas, le clapet (14) isole hémétiquement la zone épidermique traitée de la pression et de la pollution atmoshhérique. It is then possible to decouple the cartridge from the suction cup in order, for example, to add a new "vacuum dose" inside the suction cup, or to put under depressurized dressing the epidermal area poisoned during transport of the injured towards a Hospital Center. In this case, the valve (14) hemetically isolates the treated epidermal area from pressure and air pollution.
La construction de la Cartouche à vide, objet de l'invention, repose sur l'utilisation de matériaux plastiques et plasto-élastiques et/ou élastiques. The construction of the vacuum cartridge, object of the invention, is based on the use of plastic and plasto-elastic and / or elastic materials.

Elastiques les éléments 2, 8, 10 et 14. Elastic elements 2, 8, 10 and 14.
L'assemblage des éléments 9, 10 et 12 constitue le premier composant de la cartouche. The assembly of elements 9, 10 and 12 constitutes the first component of the cartridge.
Le montage du clapet (8) dans le logement réservé dans le fond du corps de pompe (1) réalise le composant n0 2 de la cartouche. The mounting of the valve (8) in the housing reserved in the bottom of the pump body (1) produces component no. 2 of the cartridge.
Assemblés par collage ou soudure, les composants 1 et 2 constituent ltessentiel de la cartouche à vide. Assembled by gluing or welding, components 1 and 2 constitute the essential part of the vacuum cartridge.
L'assemblage des éléments 2, 3, 4 et 5 (piston, tige, couvercle et anneau de tirage ) constitue le 30 et dernier composant de la cartouche. The assembly of elements 2, 3, 4 and 5 (piston, rod, cover and pulling ring) constitutes the 30 and last component of the cartridge.
L'introduction du piston (2) dans le corps de pompe (1) conditionne le positionnement définitif du 3c et dernier composant ; le collage, ou soudure, du couvercle (4) sur le haut de corps de pompe (1) termine la construction industrielle de la cartouche à vide", objet de l'invention. The introduction of the piston (2) into the pump body (1) conditions the final positioning of the 3c and last component; gluing, or welding, the cover (4) on the top of the pump body (1) completes the industrial construction of the vacuum cartridge ", object of the invention.
La construction de la, ou des, ventouses constiste en la mise en place dans l'espace, réservé à cet effet, du corps (13) de la stille 14 et du jonc (15). The construction of the suction cup (s) consists of the placement in the space, reserved for this purpose, of the body (13) of the stille 14 and of the rod (15).
Ce dernier composant, unitaire et amovible, peut être représenté par un quelconque embout (13'), lequel peut être prolongé par tout élément d'utilisation et/ou d'application du vide de la cartouche, objet de la présente invention. This last component, unitary and removable, can be represented by any tip (13 '), which can be extended by any element for use and / or application of the vacuum of the cartridge, object of the present invention.
La "Cartouche à vide, réarmable" que complète son embout amovible constitue un ensemble de moyens nouveaux, simple et robuste, capable de réaliser des dépressions pneumatiques locales importantes, applicables, en particulier, à l'aspiration de venins aussi bien qu'à la conservation et la dissécation sous vide d'échantillons de matière organiques en Laboratoires. The "resettable vacuum cartridge" which its removable end completes constitutes a set of new means, simple and robust, capable of producing significant local pneumatic depressions, applicable, in particular, to the suction of venoms as well as to the preservation and dissection under vacuum of organic matter samples in Laboratories.
