Abstract
A needle mount, or assembly for installation of a tubular needle on the forward end of an essentially otherwise conventional syringe. The syringe includes the conventional barrel, reciprocable plunger mounted from the rearward end and within the bore of the barrel, and tubular needle mounted on the forward end of the barrel. The bore at the forward end of the barrel is provided with a conical entry feature, and a hub with a central opening which can be aligned upon the conical entry is mounted on the forward end of the barrel. The needle mount is constituted of a tubular extension member within an end of which the needle can be inserted, the opposite end thereof being sealed for extension into the conical entry, the needle mount further including a stop located on the tubular extension member intermediate the sealed end and its forward terminal end, a coil spring concentrically and coaxially mounted on the tubular extension member forward of the stop, and cap engagable with the hub within which the spring end portion of the tubular extension member and stop thereof are retained, and seated, to form a composite assembly for installation and buffered retention of the needle in place on the forward end of the barrel.
