First Claim
Patent Images
1. In a combination hypodermic syringe and removable radioactive shield therefor, the improvement comprising:
- said syringe having a main barrel element of given outer diameter, a needle element on a distal end thereof, and a needle cover enclosing said needle element and having an outer diameter greater than that of said barrel element;
said shield including a generally tubular body defining an axially disposed through bore therein of diameter at least equal to the diameter of said needle cover, set screw means penetrating said tubular body and having an inner end thereof adapted to contact an outer surface of said main body of said syringe; and
an arcuately shaped sleeve having an outer surface of radius corresponding to that of said through bore, and an inner surface of radius corresponding to said given diameter of said main barrel of said syringe, said sleeve being selectively positioned between said through bore and said main barrel element to lie at least partially along the axis of said set screw means to position said main barrel coaxially relative to said through bore, and permit selective withdrawal of said syringe with attached needle cover through said last mentioned bore.

Abstract
A radioactive syringe shield for protecting a user from radiation emanating from a radioactive material disposed within an enclosed syringe, characterized in the provision of a removable arcuately shaped bushing positionable in the bore of the shield for decreasing the effective diameter thereof to support a syringe barrel against a single set screw. The bushing is inserted with the syringe barrel into an oversized bore in the shield permitting passage of the needle of the syringe with an intact needle cover, thereby maintaining sterility of the needle.
