ABSTRACT:
A protective device, for a hypodermic needle having a cylinder with a plunger coaxial along an axis, and an end wall with a projecting needle, is provided. The device has an annular, radially projecting web portion of fabric or plastic material, which has a radially inner edge and a radially outer edge. The device has a collar, which is joined to the radially inner edge. The collar is mounted on the cylinder end wall. The device also has a closing drawstring, which is threaded inside a turned-in edge portion of the radially outer edge of the web portion. The web portion has first, second third, and fourth rigid members, composed of a plastic material or the like. The first rigid member has a bent end portion. The rigid members form a box-like structure around the needle, when the web portion is in a closed condition. The rigid portions each have beveled side edges. The cylinder has an adhesive tape for holding taut the drawstring, when the web portion is in a closed condition. The cylinder end wall has a neck portion, on which the collar is mounted. The neck portion has a tapered portion supporting the needle. When the needle is withdrawn from the skin of a patient, the protective device prevents blood from the puncture from coming into contact with the operator of the hypodermic needle.
