Injection syringe with protective sleeve covering needle comprises sleeve release mechanism with inhibitor controlling release until completion of injection

摘要

A syringe, comprising a barrel (10), needle (11) and plunger (12), with a protective sleeve (16) to cover the needle after injection when a release mechanism (30) is actuated, comprising an inhibitor (34) that has two operating positions, one at the end of injection in which the sleeve is not released, and a second in which the sleeve is released to deploy over the needle, is new. A syringe, comprises a barrel (10), needle (11) and plunger (12), with a protective sleeve (16) to cover the needle after injection when a release mechanism (30) is actuated, comprising an inhibitor (34) that has two operating positions, one at the end of injection in which the sleeve is not released, and a second in which the sleeve is released to deploy over the needle. In the first position it moves together with the plunger, and in the second it separates from it to release the sleeve.
