Abstract
Abstract A syringe shield having an inner generally cylindrical shell formed of plastic material. The shell has an elongated slot extending longitudinally therein and is open-ended at its rear end and narrows radially inward at its front end to form a tapered portion. A generally cylindrical body formed of radiation-shielding material is proportioned such that its inner surface conforms generally to the outer surface of the inner shell. The body has an elongated slot therein which is aligned with the slot in the inner shell. An outer shell, formed of plastic material, conforms to the shape of the outer surface of the body and has an elongated slot aligned with the slots in the inner shell in the body. An elongated optically transparent radiation shielding member is proportioned to fit in the elongated slot in the body. In the preferred embodiment of the invention the inner shell has a plurality of flexible plastic protrusions on the inner surface thereof. In this embodiment, the body tapers radially toward its axis at the front end thereof and a plastic ring-shaped collar joins the front edges of the inner and outer shells.
