ABSTRACT:
A conventional hypodermic syringe comprises a cylindrical body with an axial funnel section at one end and an open mouth with lateral fixed wings at its other end, a piston slidably engaged through its mouth and into the main body, and a needle frictionally secured to the funnel section via a socket connector. The needle defines a bevelled free end. For proper handling of the syringe when piercing the patient's skin the bevel plane of the needle must be parallel to the longitudinal axis of the wings with the needle bevel facing away from the skin. In the present invention, the wings are not fixed to the body but an adjustable winged collar is rotatably mounted by friction fit about the mouth through an inner face thicknesswise groove engaged by an outturned flange from the mouth, wherein the collar may rotate 360.degree. but with some level of frictional resistance. By rotatably adjusting de visu the orientation of the collar wings relative to the orientation of the bevel plane of the needle tip, instead of rotating the needle itself, the nurse does not have to touch the needle.
