Abstract

The present invention relates to a device making it possible to protect the users of medical syringes from the risk of injury by contaminated needles. It consists of a slide mounted on the end of the syringe, which can be moved telescopically, thus preventing any contact with the tip of the contaminated needle after sampling blood or an injection.

Description

SERINGUE DE SECURITE POUR PRISES DE SANG ET INJECTIONS
La présente invention concerne un dispositif de protection de la pointe des aiguilles des seringues médicales pour prises de sang et injections évitant lorsque l'aiguille est retirée de la veine ou du muscle le risque de blessure (piqure par exemple) de l'utilisateur comme celà peut se produire avec les seringues classiques.SAFETY SYRINGE FOR BLOOD TAKING AND INJECTION
The present invention relates to a device for protecting the tip of the needles of medical syringes for blood samples and injections, avoiding the risk of injury (sting for example) of the user when the needle is withdrawn from the vein or muscle. can occur with conventional syringes.

Le risque de blessure de l'utilisateur par l'aiguille souillée après utilisation doit-être impérativement écarte, afin d'éviter la contamination dans les éventuelles opérations sur sujets à maladies transmissibles ou hautement contagieuses .The risk of injury to the user by the contaminated needle after use must be avoided, in order to avoid contamination in any operations on subjects with communicable or highly contagious diseases.

La seringue > selon l'invention, comporte à cet effet un coulisseau cylindrique fenêtré à déplacement téléscopique . Un circlips circulaire verrouille le corps de la seringue et le coulisseau , ce qui condamne une possible sortie, après usage de l'aiguille, du coulisseau protecteur. Un fenestrage disposé circulairement permet la bonne tenue du corps de la seringue pour l'enfoncement de l'aiguille
La commande du déplacement télèscopique en position de protection de la pointe de l'aiguille se fait ^ maintenant des premiers doigts de la main gauche la collerette médiane du coulisseau, en saisissant avec les trois premiers doigts de la main droite la collerette de la seringue et en tirant vers l'extérieur.La mobilisation des deux mains lors de la sortie de l'aiguille conforte la sécurité.The syringe> according to the invention, has for this purpose a cylindrical slide window with telescopic movement. A circular circlip locks the syringe body and the slide, which prevents a possible exit, after use of the needle, from the protective slide. Circular fenestration allows the syringe body to stay in place for needle insertion
The control of the telescopic movement in the protective position of the tip of the needle is done ^ now with the first fingers of the left hand the middle collar of the slide, by grasping with the first three fingers of the right hand the collar of the syringe and by pulling outwards. The mobilization of both hands when the needle comes out improves safety.

Le coulisseau est réalisé en une matière rigide, plastique par exemple
Pour des raisons de contamination ces instrumentations aprés un seul usage sont à détruire .The slide is made of a rigid material, plastic for example
For reasons of contamination these instruments after a single use are to be destroyed.

La figure I représente la seringue nue, sans le coulisseau.Figure I shows the naked syringe, without the slide.

La figure 2 représente en demi coupe longitudinale, le dispositif , selon l'invention
en position de pénétration de l'aiguille.Figure 2 shows in longitudinal half section, the device according to the invention
in needle penetration position.

La figure 3 représente le dispositif selon l'invention, , en position de protection de l'aiguille. Figure 3 shows the device according to the invention, in the needle protection position.

Le dispositif représenté sur la figure 2 comporte une seringue (t) avec une gorge circulaire (4) suivie du nez d'assemblage de l'aiguille (3). La figure 2 montre en demi coupe un coulisseau (2) ajouré de quatre fenêtres (7)assurant la prise entre le pouce et l'index de la seringue (I) pour la pénétration de l'aiguille (3).The device shown in Figure 2 includes a syringe (t) with a circular groove (4) followed by the needle assembly nose (3). Figure 2 shows in half section a slide (2) perforated with four windows (7) ensuring the grip between the thumb and the index finger of the syringe (I) for penetration of the needle (3).

Le coulisseau est constitué de trois parties : une partie tronconique creuse (2),(protecteur), une partie fenestrée (7)3 une partie munie d'une collerette et d'une entaille (5) logement du circlips.The slide consists of three parts: a hollow frustoconical part (2), (protector), a fenestrated part (7) 3 a part provided with a flange and a notch (5) housing the circlip.

La figure 4 représente le circlips à section torique dont les parties (8) s'engagent dans l'entaille du coulisseau (2) et dans la gorge (4) de la seringue ( 1 ) ce qui provoque le verrouillage de la seringue (1) et du coulisseau protecteur (2). Figure 4 shows the circlip with toric section whose parts (8) engage in the notch of the slide (2) and in the groove (4) of the syringe (1) which causes the locking of the syringe (1 ) and the protective slide (2).

La caractéristique du dispositif selon l'intervention est d'être d'une simplicité sans égal et d'un maniement aisé.The characteristic of the device according to the intervention is to be of unequaled simplicity and easy handling.

Le dispositif selon l'invention est particulièrement destiné sécurité des manipulations lors des opérations de prises de sang et d'injections .The device according to the invention is particularly intended for safe handling during blood sampling and injection operations.

Comme il va de soi l'invention ne se limite pas au seul mode de mise en oeuvre de ce procédé , ni au seul dispositif pour sa mise en oeuvre , décrit cl-dessus à titre d'exemple; elle embrasse au contraire toutes les variantes sans pour autant sortir du domaine de l'invention. As it goes without saying, the invention is not limited to the only mode of implementation of this method, nor to the only device for its implementation, described above by way of example; on the contrary, it embraces all variants without departing from the scope of the invention.
