Hypodermic needle protective cover

The invention discloses a hypodermic needle protective cover comprising a sleeve having an open end (30) accommodating a needle device (22,24) and a portion of a syringe cylinder (18) and a closed end (32) having an opening (34) through which the needle device (22,24) passes through a positioning element (44) in the sleeve, and a positioning element (4) 4) there is an opening of a meshing needle device (22,24), and the sleeve has at least one member for releasing the locating element (44) and an offset element (48) between the locating element and the closing end (32) in the sleeve. When in use, the reverse pressure exerted by the patient's skin on the closed end (32) causes the positioning element (44) to rotate out of the member, thus causing the sleeve to be released from the working state and offset to a resting state. When the needle is removed from the patient, the sleeve is offset to cover the needle (22).
