La caractéristique du dispositif selon cette invention est d'être d'une simplicité extrême, donnant aux utilisateurs un moyen tout à fait facilité de réaliser une prise de sang tout en leur assurant une sécurité complète. The feature of the device according to this invention to be extremely simple, giving users a way quite easy to perform a blood test while ensuring their complete safety.

Le retour automatique de l'aiguille à la position de protection est la caractéristique fondamentale du système car elle ne demande aucun geste supplémentaire par rapport aux habitudes acquises en matière de prise de sang, soustrayant ainsi sans aucune intervention extérieure, la pointe de l'aiguille à toute possibilité de blessure The automatic return of the needle protection position is the fundamental characteristic of the system because it requires no additional action with respect to habits acquired for blood sampling and subtracting without any outside intervention, the tip of the needle any possibility of injury
Or. le dispositif tel que décrit ci dessus comporte un risque de blessure accidentelle. Or. The device as described above involves the risk of accidental injury.

Les études réalisées par les services d'hygiène de plusieurs centres hospitaliers ont permis de mieux cerner les circonstances de survenue des accidents. Studies by the health authorities of several hospitals have allowed a better understanding of accidents occurred in the circumstances.

Ils intéressent en effet l'ensemble du "circuit normal" de l'aiguille de son utilisateur a sa destruction. They interested indeed the entire "normal circuit" of its user needle destruction.

En effet, ces accidents surviennent toujours quand il y a justement, une faute de manipulation ou des circonstances inhabituelles telles qu'un geste maladroit de l'opérateur ou du malade . Indeed, these accidents always occur when there is just a lack of manipulation or unusual circumstances such as a clumsy gesture of the operator or the patient. ou encore et surtout une simple négligence ces circonstances paraissent impossible à éviter compte tenu des techniques de soins actuelles et des conditions de travail or simple negligence and above these circumstances seem impossible to avoid given the current treatment techniques and working conditions
Dans cette optique: d'une part; In this perspective: firstly; tous les systèmes existants ou proposés, qu'ils s'agissent des capots d'aiguilles des récipients spécifiques ou des pièces rapportées sur les seringues ou les aiguilles telles que des coulisseaux ou des capots, dès l'instant où ils nécessitent un geste particulier supplémentaire de l'opérateur, , alors que l'aiguille a été retirée de la veine et se trouve à l'air libre en position dangereuse, sont inefficaces, ce geste n'étant ou ne pouvant plus être fait. all existing or proposed systems, be they needles hoods specific containers or patches on the syringes or needles such as sliders or covers, from the moment they need extra special gesture of the operator, while the needle was removed from the vein and is located in the open unsafe position, are ineffective, this gesture is or can no longer be done.

La conception du système de ponction auto-protégé, automatique, tel que décrit est donc un premier point indispensable. The design of the self-protected puncture system, automatic, as described is a first essential item.

Le retour automatique de l'aiguille à la position de protection est la caractéristique fondamentale de ce système car elle ne demande aucun geste supplémentaire par rapport aux habitudes acquises en matière de prise de sang, soustrayant ainsi sans aucune intervention extérieure, la pointe de l'aiguille à toute possibilité de blessure The automatic return of the needle protection position is the fundamental characteristic of this system because it requires no additional action with respect to habits acquired for blood sampling and subtracting without any external intervention, the tip of the needle possible injury
Mais d'autre part But on the other hand
Le disposif tel que décrit, comporte un risque de dégagement accidentelle de l'aiguille, notamment par exemple si un objet voisin vient appuyer sur le manchon souple, alors qu'on a pu l'oublier sur une table de soins ou introduit dans un sac souple, l'aiguille pouvant alors blesser une personne autre que celle qui a fait la prise de sang. The disposif as described, carries the risk of accidental release of the needle, particularly for example if a nearby object bears on the flexible sleeve, then we could forget about a treatment table or placed in a bag flexible, then the needle may injure a person other than the one who made the blood sample.

Le dispositif suivant la présente invention comporte, comme dans le procédé antérieur, un protecteur rainuré (3), logement de l'aiguille (2). The device according to the present invention comprises, as in the prior process, a protective groove (3), needle housing (2).

Mais à la partie antérieure de ce protecteur (3) est monté un capuchon court (15). But at the anterior part of the shield (3) is mounted a short cap (15).

glissant juste. just sliding. dont le positionnement initial antérieur permet le dégagement de l'aiguille (2) normalement quand l'utilisateur s'apprête à faire leprélèvement de sang. whose previous initial positioning allows the disengagement of the needle (2) normally when the user is about to make blood leprélèvement.

Quand l'aiguille (2) est retirée de la veine et qu'elle est retournée à sa position initiale dans le protecteur rainuré (3), l'opérateur va d'une simple pression du dispositif contre un objet quelconque. When the needle (2) is removed from the vein and is returned to its initial position in the grooved protector (3), the operator goes from a simple pressure of the device against an object. provoquer le glissement antéropostérieur du capuchon (15) sur le protecteur (3) bloquant ainsi l'aiguille (2) dans le protecteur (3), et rendant de cette façon, son dégagement accidentel impossible. cause the anteroposterior sliding of the cap (15) on the shield (3) thereby locking the needle (2) in the shield (3), and making in this way, its possible accidental release.

Avantageusement, une gorge circulaire femelle (14) placée sur le protecteur rainuré (3) permettra l'encliquetage sur ledit protecteur du capuchon !15) par la présence à son niveau d'une gorge male (13) complémentaire, bloquant ainsi définitivement le système. Advantageously, a female circular groove (14) provided on the grooved protector (3) allows the detent over said protective cap! 15) by the presence in its level of a male groove (13) complementary, thus blocking the system permanently .

Comme il va de soi, l'invention ne se limite pas au seul mode de mise en oeuvre de ce procédé décrit ci-dessus à titre d'exemple, elle embrasse au contraire toutes les variantes sans pour autant sortir du domaine de l'invention. It goes without saying that the invention is not limited to one implementation mode of the method described above as an example, it encompasses all the variants without departing from the scope of the invention .
