A needle protective assembly (10) includes a ratchet (20) and pawl (28) arrangement for permitting the unidirectional movement of a protective sleeve (14) along a body (12) of a dispenser, such as a hypodermic syringe. The sleeve (14) is adapted to cover a standard Y-site diaphragm (46), and includes a lock (26) to secure the sleeve to the Y-site while in use. The assembly may also include indicia on the exterior thereof to measure the amount of needle exposed beyond the end of the sleeve, if the sleeve is not in its fully extended position. The assembly may further include a luer lock (34), for attaching the assembly to pre-existing standardized fittings.

Un ensemble (10) protecteur d'aiguille comprend un agencement d'encliquetage (20) et de cliquets (28) permettant le mouvement unidirectionnel d'un manchon protecteur (14) le long d'un corps (12) d'un distributeur, tel qu'une seringue hypodermique. Le manchon (14) est adapté pour recouvrir un diaphragme de site Y standard (46), et il comprend un dispositif de blocage (26) destiné à fixer le manchon sur le site Y lors de l'utilisation. L'ensemble peut comprendre également des marques sur sa partie extérieure afin de mesurer l'exposition de l'aiguille au-delà de l'extrémité du manchon, si ce dernier n'est pas dans sa position entièrement déployée. L'ensemble peut également comprendre un dispositif de blocage de type Luer (34) permettant de fixer l'ensemble à des raccords standards préexistants.
