Hypodermic syringe finger grip

摘要

Finger grip (1) for the plunger of a hypodermic syringe has three recessed zones (32,34,36) to allow the grip to be pushed sideways on to the syringe. The first recess (32) holds a glass flange ring projecting from the hypodermic barrel cylinder. The second recess (34), is a leading extension of the first (32), and holds the near end of the glass cylinder barrel. The third recess (36), is a trailing extension of the first (32), and allows entry for the plunger shaft but not the plunger. The grip has two extending side surfaces (30,31) for the fingers. The finger grip is a one-piece unit of plastic, and preferably of polyethylene.
