Abstract: An improved injection port (1) for a single-use syringe is described. One embodiment of the injection port has a one-way valve system for making it more difficult to reuse the syringe (2). The one-way valve system has a flap or diaphragm valve (6) housed in a valve chamber (11) at the proximal end of port cylinder (45). When the valve (6) is seated against valve seat (51) on valve cap (5), refilling of the syringe is blocked. During injection, the valve (6) unseats and moves toward radial ribs (7), allowing flow of medicament into the proximal end of a needle (2). Another embodiment of the injection port (1) includes longitudinal grooves (8) on the interior surface of the chamber (12) at the distal end of cylinder (45). The grooves (8) vent pressure from a Luer syringe inserted in the distal end of the cylinder (45).

Abstract: The present invention is a prosthetic prehensor with two members extending in the same direction. One of the members rotates about a parallel axis removed from the first member until it contacts the first member. In the preferred embodiment, the two members are curved plates, one simulating a thumb and the other being wider and simulating a palm. The thumb plate rotates around a base plate which is coupled to the end of an arm. The thumb plate can contact the palm plate in either of two directions. This allows two types of gripping for fine objects and larger objects. The use of plates that are curved allows for a more aesthetic design than metal hooks.

Abstract: An article for protecting a substrate includes a preshaped member having a shape similar to that of the substrate being protected, the article having a thin layer of gel disposed in intimate contact with an inner surface of the member such that the gel is disposed in intimate contact with the substrate when the member is disposed therearound. Preferably, the gel comprises an open looped three-dimensional network, the gel being relatively soft, elastic, and having an ultimate elongation in excess of 100%.
