CA 2119982

A needle holder assembly having a sleeve that slidably receives a needle holder having a needle assembly attached thereto. After the need holder assembly has been used to collect a sample of body fluid, the needle holder is slid from its initial retracted position to a permanently locked extended position. In the extended position the used needle is contained within the sleeve of the assembly and can be disposed of. The assembly of the present invention includes a mechanism for smoothly releasing the needle holder from the retracted position, an improved mechanism for permanently and securely locking the needle holder in the extended position, and a body fluid collection channel around the distal end of the sleeve that prevents body fluid from splattering from the distal end of the assembly, when the sleeve is locked in the needle holder.

Ensemble porte-aiguille comportant une gaine qui reçoit de façon coulissante le porte-aiguille sur lequel est montée une aiguille. Une fois que l'ensemble porte-aiguille a servi à prélever un échantillon de liquide organique, l'utilisateur le fait coulisser de sa position initiale rétractée jusqu'à une position allongée verrouillée en permanence. Dans la position allongée, l'aiguille utilisée est contenue dans la gaine du porte-aiguille et peut alors être jetée. L'ensemble de l'invention comprend : un mécanisme permettant de libérer avec aisance le porte-aiguille de sa position rétractée; un mécanisme amélioré pour verrouiller le porte-aiguille à la position allongée en permanence et de façon sécuritaire; et un canal collecteur de liquide organique se trouvant autour de l'extrémité distale de la gaine, qui prévient toute éclaboussure de liquide provenant de l'extrémité distale de l'ensemble lorsque la gaine est verrouillée dans le porte-aiguille.
