Needle sheathing device with flexible end-piece for syringe

Abstract

The invention relates to a safe support device for a syringe, said support comprising a support sheath for the body of a syringe, and safety means which comprise an inner sheath suitable for sliding relative to said support sheath between a waiting retracted position, in which said inner sheath is substantially retracted inside said support sheath, and an active protection position, in which said inner sheath projects from said support sheath. The inner sheath has a free end portion formed by a flexible end-piece. The invention also relates to an assembly comprising such a safe support device and a syringe having a body, a piston and a needle disposed at one end of said body.

1 . A safe support device for said syringe, said safe support device comprising:
 a support sheath for receiving the syringe therein,   an inner sheath slidable relative to said support sheath between a waiting retracted position, in which said inner sheath is substantially retracted inside said support sheath, and an active protection position, in which said inner sheath projects from said support sheath, wherein said inner sheath has a free end portion formed by a flexible tubular end-piece, wherein said inner sheath comprises a rigid first portion co-operating with said support sheath, and a second portion secured to said first portion by said flexible end-piece, said end-piece being made from a material having a Shore hardness lying in the range of 30 Hs to 80 Hs; and   a drive means for projecting said inner sheath from said support sheath in correspondence with an actuation of a syringe received in the support sheath;   wherein said end piece is fixed to said first portion by a projecting member provided on one of said first portion and said end piece, and a notch provided on the other of said first portion and said end-piece.   
   
   
       2 . A safe support device for said syringe, said safe support device comprising:
 a support sheath for receiving the syringe therein,   an inner sheath slidable relative to said support sheath between a waiting retracted position, in which said inner sheath is substantially retracted inside said support sheath, and an active protection position, in which said inner sheath projects from said support sheath, wherein said inner sheath has a free end portion formed by a flexible tubular end-piece, wherein said inner sheath comprises a rigid first portion co-operating with said support sheath, and a second portion secured to said first portion by said flexible end-piece, said end-piece being made from a material having a Shore hardness lying in the range of 30 Hs to 80 Hs; and   a drive means for projecting said inner sheath from said support sheath in correspondence with an actuation of a syringe received in the support sheath;   wherein said flexible end-piece has a tapering free end.
