Injection device for medical and veterinary use preventing contaminations

Abstract

Abstract The invention relates to an injection device. <??>The body of the valve connection piece (36) is provided with a means serving as a lever (39) which is actuated by a movable finger (40); the said movable finger (40) is mounted integral with the chamber of the movable cylinder (27) which receives the end (25) of the stabilising rod (24); the said body of the valve connection piece (36) is thus controlled by a means serving as a detector of the penetration of the needle (31) into the skin; as soon as the needle (31) is withdrawn from the skin, the valve (35) closes the orifice of the body of the valve connection piece (36) which permits the passage of liquid from the syringe (4) towards the needle (31). <??>This apparatus is intended for performing intradermal, subcutaneous or intramuscular injections for medical or veterinary use, and more particularly in mesotherapy, aquapuncture, vaccinations or allergy tests. <IMAGE>
