ABSTRACT The invention provides a needle arrangement (30) for a low-vacuum wound drainage system. The needle arrangement (30) includes a needle (32) and a needle retriever (34). The needle (32) has a sharpened, leading end (36) for piercing the skin of a patient, and a first locking formation (42) proximate the leading end of the needle. The needle retriever (34) has a second locking formation (48) for engaging the first locking formation (42) on the needle (32) when the needle retriever (34) is located over the leading end (36) of the needle (32), thereby to lock the needle retriever (34) to the needle, and a handle (52) for allowing the needle retriever (34) to be held and pulled by a user, thereby to retrieve the needle (32) from the patient.

L'invention concerne un agencement d'aiguille (30) destiné à un système de drainage de plaies par faible dépression. Ledit agencement d'aiguille (30) comprend une aiguille (32) et un dispositif de récupération (34) d'aiguille. Ladite aiguille (32) comprend une extrémité antérieure (36) aiguisée permettant de percer la peau d'un patient, et une première formation de verrouillage (42) disposée à proximité de l'extrémité antérieure de l'aiguille. Le dispositif de récupération (34) d'aiguille comprend une seconde formation de verrouillage (48) destinée à coopérer avec la première formation de verrouillage (42) de l'aiguille (32) lorsque ledit dispositif de récupération (34) d'aiguille est placé sur l'extrémité antérieure (36) de l'aiguille (32), ce qui permet de verrouiller le dispositif de récupération d'aiguille (34) sur l'aiguille. Une poignée (52) permet à un utilisateur de tenir le dispositif de récupération (34) et de le tirer, ce qui permet de récupérer l'aiguille (32) du patient.
