Abstract
A combination needle sheath and sterility package comprising a lower needle cover to surround and protect the distal end of a sterile, double ended hypodermic needle cannula and an upper sleeve to surround and protect the proximal end of the cannula. The upper sleeve can be opened to permit the bore of a conventional hypodermic syringe to be received therewithin, so that the proximal end of the needle cannula can communicate fluidically with the syringe cylinder. By virtue of the needle sheath/sterility package as disclosed herein, the sterility of the needle cannula may be reliably preserved during handling and prior to use, while the possibility of an accidental needle stick during attachment of the cannula to the syringe may be advantageously minimized.
