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 (ou autres systèmes voisins comparables comportant une aiguille ) 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 (or other similar comparable systems comprising a needle) for blood tests and injections preventing, when the needle is withdrawn from the vein or the muscle, the risk of injury ( for example) of the user as can happen with conventional syringes.
Le risque de blessure de l'utilisateur par l'aiguille souillée après utilisation doit-être impérativement écarté, 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 imperatively avoided, in order to avoid contamination in any operations on subjects with communicable or highly contagious diseases.
La seringue comporte selon l'invention un levier capot basculant articulé au niveau de la fixation des aiguilles, qui recouvre et capote la partie pointue.According to the invention, the syringe comprises a tilting hood lever articulated at the level of the needles attachment, which covers and covers the pointed part.
Le levier peut-être manoeuvré pour le décapotage de l'aiguille indifféremment des deux mains en exercant une pression de l'index sur un ressort gachette, conjuguant l'effet de rappel en position de protection de la pointe et de verrouillage du levier capot.The lever can be operated for the uncapping of the needle indifferently with both hands by exerting a pressure of the index finger on a trigger spring, combining the effect of return to the tip protection position and locking of the hood lever.
Le dispositif est réalisé en une matière rigide, plastique par exemple.The device is made of a rigid material, plastic for example.
Pour raisons de contamination, ces instrumentations après un seul usage peuvent être détruites.For reasons of contamination, these instruments after a single use can be destroyed.
La figure I représente en demi coupe longitudinale; le dispositif selon l'invention.Figure I shows in longitudinal half section; the device according to the invention.
La figure 2 représente en vue de dessus, la partie du capot en coupe partielle faisant apparaître la pointe de l'aiguille.2 shows a top view, the part of the cover in partial section showing the tip of the needle.
La figure 3 représente en coupe le dispositif des axes articulaires : levier capot et ressort de rappel-verrouillage.Figure 3 shows in section the device of the articulated axes: hood lever and return-lock spring.
Le dispositif représenté sur la figure I comporte une seringue (1) avec aiguille de prise de sang (2); au niveau de la base de l'aiguille apparaît la disposition de l'axe articulaire (3) du levier capot (4) protecteur de pointe et des deux axes articulaires du ressort (5) assurant le rappel du levier capot et son verrouillage en (6). Au quart de son extrémité > le levier capot porte une saillie (7). Lorsque l'aiguille est engagée dans la veine, la saillie s'appuie sur le bras, maintenant le débattement angulaire élastique
avec une très faible pression, exerçant en pince entre sabot et aiguille, neutralisant le verrouillage du levier capot.The device shown in Figure I comprises a syringe (1) with blood drawing needle (2); at the level of the base of the needle appears the arrangement of the articular axis (3) of the hood lever (4) protector of the tip and of the two articular axes of the spring (5) ensuring the return of the hood lever and its locking in ( 6). At a quarter of its end> the hood lever carries a projection (7). When the needle is engaged in the vein, the projection rests on the arm, maintaining the elastic angular movement
with very low pressure, exerting forceps between shoe and needle, neutralizing the locking of the hood lever.
Cette saillie (7) peut dans une autre application être placée plus prés de la base du levier capot (4) pour permettre une plus grande ouverture de l'angle levier capot-aiguille .This projection (7) can in another application be placed closer to the base of the cover lever (4) to allow greater opening of the cover lever-needle angle.
Le dispositif représenté sur la figure 3 en coupe a, montre le ressort ( 5) verrouillant le levier capot (4).The device shown in Figure 3 in section a, shows the spring (5) locking the hood lever (4).
La manoeuvre d'ouverture du levier capot (4) est obtenue par pression de l'index sur la gachette (5).The opening operation of the hood lever (4) is obtained by pressing the index finger on the trigger (5).
Les caractéristiques du ressort (5), section torique, figure 5, sont: effet de rappel bride de verrouillage et gachette de manoeuvre.The characteristics of the spring (5), O-section, Figure 5, are: return effect locking flange and actuating trigger.
Le système doit être réalisé de façon robuste, assurant une bride verrou sans élasticité pouvant faire varier l'effet de rappel, avec une extrême souplesse par le choix des entraxes: X et Xi. La réduction des entraxes apporte la légèreté du rappel.The system must be made robustly, ensuring a lock flange without elasticity that can vary the return effect, with extreme flexibility by the choice of the centers: X and Xi. The reduction in the center distances brings the lightness of the recall.
Le dispositif selon l'invention est particulièrement destiné à la sécurité dans les manipulations lors des opérations de prises de sang. The device according to the invention is particularly intended for safety in handling during blood sampling operations.
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 à la sécurité des manipulations lors des opérations de prises de sang et d'injections.The device according to the invention is particularly intended for the safety of 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 dispositi#f pour sa mise en oeuvre, décrit ci-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.
