Title (EN) NEEDLE RETRACTION MECHANISMS
(FR) MECANISMES DE RAPPEL D'AIGUILLE
Abstract: front page image
(EN)There is disclosed a fluid handling device (2) having a needle retraction assembly adapted to bring about the retraction of a hollow needle (10) after use comprising a hollow body portion (4) provided at one end thereof with an end wall having a mounting portion (8) including a needle passage, and a hollow needle (10) having a mounting means and adapted to be movable between a first position in which a leading end portion of the needle protrudes from a front end portion of said mounting portion (8) and a second position in which the needle is withdrawn within the hollow body portion (4), said mounting means including resilient means (28) that act to bias the needle (10) into the second, withdrawn, position, said needle (10) being provided with an enlarged portion (18) at a location spaced from the leading end portion thereof, there being provided retaining means to maintain the needle in its first position until use is completed, said retaining means comprising in combination an O-ring (20) positioned in a circumferential groove (19) in said enlarged portion (18) and abutting the end of a sleeve (36) which can be forced forwardly to dislodge the O-ring (20) so as to permit the needle (10) to move from its first position into its second position under the influence of said resilient means (28).
(FR)L'invention concerne un dispositif de refoulement de liquide (2) muni d'un ensemble conçu pour le rappel d'une aiguille creuse (10) après utilisation. Le dispositif est constitué d'un corps creux (4) dont l'une des parois d'extrémité comporte une partie support (8) ayant un passage d'aiguille, et d'une aiguille creuse (10) dotée d'un bâti, mobile entre une première position à partir de laquelle son extrémité antérieure déborde de l'extrémité de la partie support susmentionnée et une seconde position où elle se trouve en retrait dans le corps creux (4). Ledit support (8) comporte un dispositif élastique (28) qui pousse l'aiguille (10) vers cette seconde position de retrait. L'aiguille (10) comporte une partie élargie (18) à une certaine distance de son extrémité antérieure et un système de retenue qui la maintient dans sa position initiale jusqu'à la fin de l'opération. Ledit système de retenue comporte, dans une rainure circulaire (19) de la partie élargie susmentionnée (18), un joint torique (20) butant sur l'extrémité d'un manchon (36) qu'il est possible de pousser pour déloger le joint torique (20) afin que l'aiguille (10) passe de la première à la seconde position par le truchement du dispositif élastique (28).
