Title
(EN) SINGLE USE SYRINGE AND INJECTING NEEDLE
(FR) SERINGUE ET AIGUILLE D'INJECTION A USAGE UNIQUE
Abstract
(EN)
A chamber (6) which forms the bottom of the female tip of a needle (2) and which is connected to the male tip of a syringe (3), is connected to an enclosure (8) which contains a bubbling blade (10) linked to a membrane (12), the enclosure itself communicating with the outside by a duct (13). The bubbling blade comprises a sealing head (11) which blocks a central hole of the membrane. Opening the hole connects the bottom of the tip to the outside, thereby preventing the needle from being reused. Applications in therapeutics.
(FR)
La chambre (6) formant le fond de l'embout femelle d'une aiguille (2), destinée à se raccorder à l'embout mâle de seringue (3), est raccordée à une enceinte (8) renfermant une lame cloquante (10) associée à une membrane (12), l'enceinte étant elle-même communicante avec l'extérieur par un conduit (13). La lame cloquante porte une tête d'obturation (11) fermant un orifice central de la membrane, dont l'ouverture fait communiquer le fond de l'embout avec l'extérieur, interdisant le réemploi de l'aiguille. Application en thérapeutique.
