ABSTRACT:
An automatic shield assembly for preventing reuse of a hypodermic needle injection device, such as a hypodermic syringe or an intravenous needle. A shield member is spring-biased outwardly towards the sharp end of the needle and maintained in this position by a retainer member which is automatically released upon application of the needle to the patient and permits the shield member to enclose and lock the needle against subsequent use upon removal of the needle from the patient.
