Title
(EN) HYPODERMIC NEEDLE SAFETY APPARATUS
(FR) APPAREIL DE SÛRETÉ POUR AIGUILLE HYPODERMIQUE
Abstract
(EN) The invention concerns a hypodermic needle safety apparatus (10) which is either manufactured as a separate unit for retrofitting to an existing hypodermic needle (28), for example the hypodermic needle of a syringe, or which is connected integrally to the needle. The safety apparatus has an end cap (16) which locates over the tip of the needle when the apparatus is in a safe condition and which can be retracted along the needle during use. A flexible, resilient support structure (20) extends alongside the needle and supports the end cap. In a relaxed state the support structure has an inwardly bowed shape that prevents retraction of the end cap. A deflecting arrangement (22) is provided which can operate to deflect the support structure from the inwardly bowed shape to a shape that allows retraction of the end cap along the needle.
(FR) L'invention concerne un appareil de sûreté pour aiguille hypodermique (10) lequel est soit fabriqué comme unité séparée pour raccordement à une aiguille hypodermique existante (28), par exemple l'aiguille hypodermique d'une seringue, soit connecté intégralement à l'aiguille. L'appareil de sûreté a un capuchon terminal (16) placé sur la pointe de l'aiguille quand l'appareil est dans une condition sûre et lequel peut être rétracté le long de l'aiguille pendant l’utilisation. Une structure de support (20) élastique flexible s'étend le long de l'aiguille et supporte le capuchon terminal. À l’état relâché la structure de support a une forme recourbée vers l’intérieur qui empêche une rétractation du capuchon terminal. Un arrangement de déviation (22) est présent pour permettre de dévier la structure de support de la forme recourbée vers l’intérieur en une forme qui permet une rétractation du capuchon terminal le long de l'aiguille.
