Description

DESCRIPTION
La présente invention concerne les appareils de désobstruction do type "aspirateur de mucosités" permettant d'éliminer toutes les secrétions se formant au niveau des voies aériennes supérieures, ou dans un orifice quelconque de l'organisme, au moyen d'un tuyau souple, non traumatisant, relié à un organe déprimogene du type trompe à eau.DESCRIPTION
The present invention relates to devices for clearing do type "mucus aspirator" to eliminate all secretions forming in the upper airways, or in any orifice of the body, by means of a flexible hose, not traumatic, connected to a depression-like organ of the water pump type.

Les appareils actuels existants ne se présentent pas sous la meme forme que la présente invention. Ils sont nombreux et de conception très variable. Les plus connus sont
- les appareils dont l'aspiration est provoquée par un moteur action
nant une membrane
- les appareils dont l'aspiration est provoquée par la dépression
d'une poire.The current existing devices are not in the same form as the present invention. They are numerous and of very variable design. The most famous are
- devices whose suction is caused by an action motor
nant a membrane
- devices whose suction is caused by depression
of a pear.

Les premiers dispositifs, bien que très appréciables au point de vue aspiration des mucosités, si on doit les utiliser en poste fixe, sont d'un emploi malaisé du fait de leur poids et de leur volume, pour une utilisation à domicile ou ambulatoire. Leur manque de maniabilité, leur aspect en eombrant et les quelques connaissances techniques qu'ils requièrent, sont autant d'aspects négatifs de leur utilisation. The first devices, although very appreciable from the point of view of suctioning mucus, if they must be used in a fixed position, are difficult to use because of their weight and their volume, for use at home or on an outpatient basis. Their lack of maneuverability, their oversized appearance and the few technical knowledge they require are all negative aspects of their use.

En revanche, les seconds sont beaucoup plus rustiques et alimentaires mais leur efficacité s'avère peu satisfaisante. On the other hand, the latter are much more rustic and edible, but their effectiveness is not very satisfactory.

Le dispositif que nous proposons, dénommé NOBVA, permet par sa capacité d'action et de mise en oeuvre, par son efficacité et son absence de risques pour le sujet, d'en faire un outil très appréciable pour les secours urgents. Ainsi, cet appareil devrait voir son champ d'application s'élargir aux différentes interventions de secourisme, car il allie la rapidité, l'efficacité, la fiabilité et la simplicité d'emploi. The device that we are proposing, called NOBVA, allows, by its capacity for action and implementation, by its effectiveness and its absence of risks for the subject, to make it a very appreciable tool for urgent aid. Thus, this device should see its field of application widen to the various first aid interventions, because it combines speed, efficiency, reliability and simplicity of use.

La figure 1 représente, en coupe, le dispositif NOBVA selon l'invention. FIG. 1 represents, in section, the NOBVA device according to the invention.

La figure 2 représente, en coupe, une variante de ce dispositif lors de la nécessité d'un prélèvement. Figure 2 shows, in section, a variant of this device when the need for a sample.

Le dispositif représenté sur la figure 1 se compose de trois éléments
- une trompe à eau de longueur 85 mm, démontable en deux parties pour un nettoyage éventuel,
- un système de raccordement à la source de pression motrice,
- un tuyau souple permettant l'aspiration à distance. The device shown in Figure 1 consists of three elements
- a 85 mm long water pump, removable in two parts for possible cleaning,
- a connection system to the source of driving pressure,
- a flexible hose allowing remote suction.

La trompe à eau comporte un corps (1) de diamètre intérieur 20 mm, avec une tubulure latérale d'aspiration et une tubulure tronconique d'évacuation. Sur le corps se visse de façon étanche l'injecteur (2) comportant une buse (7) de faible diamètre pour le passage du fluide moteur, et un raccord cannelé à sa partie supérieure. Le corps et l'injecteur sont réalisés en moulage pari injection de matière plastique. The water pump has a body (1) with an internal diameter of 20 mm, with a lateral suction tube and a frustoconical evacuation tube. On the body is tightly screwed the injector (2) comprising a nozzle (7) of small diameter for the passage of the working fluid, and a barbed connection at its upper part. The body and the injector are made by injection molding of plastic material.

Le raccordement à la source de fluide moteur se fait par l'intermédiaire d'un manchon (3) en matière plastique souple, de 50 mm de long, comportant un collier de serrage (5) permettant de fixer le dit manchon sur n'importe quel robinet courant. Le diamètre interne de ce manchon peut être modifié par une ou plusieurs bagues (4) en matière plastique souple, permettant le raccordement le plus étanche possible au robinet. The connection to the source of working fluid is made by means of a sleeve (3) of flexible plastic material, 50 mm long, comprising a clamp (5) allowing the said sleeve to be fixed on any what a running tap. The internal diameter of this sleeve can be modified by one or more rings (4) of flexible plastic material, allowing the most tight connection possible to the tap.

La tubulure latérale de la trompe à eau est telle qu'elle permet l'em- boitement étanche sans autres systèmes de fixation d'un tuyau (6) en matière plastique souple de diamètre 5 mm, de longueur variable, ce qui permet l'aspiration à une distance plus ou moins grande de la source d'énergie. The lateral tubing of the water pump is such that it allows the watertight fitting without other systems for fixing a flexible plastic pipe (6) of diameter 5 mm, of variable length, which allows the suction at a greater or lesser distance from the energy source.

Dans l'appareil décrit, la longueur du tuyau souple est de 1,50 m.In the device described, the length of the flexible hose is 1.50 m.

Le poids de l'appareil est de 80 g environ. The weight of the device is approximately 80 g.

Le dispositif représenté par la figure 2 comporte en outre un flacon stérile (8) pour recueillir les secrétions aspirées, interposé par la tromà eau et le point de prélèvement. The device represented by FIG. 2 also comprises a sterile bottle (8) for collecting the secretions sucked in, interposed by the tromà eau and the sampling point.

Le faible encombrement et le poids insignifiant de cet appareil permettent donc son utilisation, comme aspirateur de mucosités ou d'autres liquides, dans n'importe quelles conditions. Il suffit d'avoir à proximité une source de débit de fluide légèrement sous pression (eau, gaz comprimé), soit en installation fixe, soit en installation portative. Il ne nécessite, en plus, aucune connaissance technique particulière. Il ne présente, enfin, aucun danger pour la personne utilisatrice ou pour le sujet sur lequel est effectuée l'aspiration (l'augmentation possible de la pression ou du débit du fluide moteur ne provoquant en aucun cas une aspiration traumatique). The small size and insignificant weight of this device therefore allow its use, as a vacuum cleaner for mucus or other liquids, in any conditions. It is sufficient to have a source of slightly pressurized fluid flow nearby (water, compressed gas), either in a fixed installation or in a portable installation. In addition, it does not require any special technical knowledge. Finally, it does not present any danger to the user or to the subject on whom the aspiration is carried out (the possible increase in the pressure or the flow of the working fluid not in any case causing traumatic aspiration).

Les applications du dispositif NOBVA peuvent être multiples, mais son but premier est d'être employé comme aspirateur de mucosités nasales chez le petit enfant avant 2 ans dont le mouchage est inefficace, et dont les secrétions, souvent purulentes sont source d'infections rhinophraryngées à répétition. The applications of the NOBVA device can be multiple, but its primary purpose is to be used as a nasal mucus aspirator in small children before 2 years old whose blowing is ineffective, and whose secretions, often purulent, are a source of rhinophraryngeal infections. repetition.
