Abstract
A syringe has a syringe body having an outer end, a needle holder on the outer end, a needle fixed on the needle holder so that liquid in the body can be expressed through the needle, and a cap removably fitted to the body over the needle holder and enclosing the needle holder and needle. A flexible envelope engaged over the needle has an inner end fixed to the needle holder and an outer end adapted to be easily pierced by the needle. The envelope is compressible parallel to the needle. The envelope is generally cylindrical and formed as a cuff, for instance with annular corrugations allowing it compress axially very easily.
