Abstract
Abstract A hypodermic needle-cap handling device (10) includes a thin rigid plate (12) having an open ended slot (24) therein and a cap holder (16) mounted on one side of plate adjacent the slot for holding a needle cap (36) that has been removed from a hypodermic needle (58) with the aid of handling device. A syringe (54) can be manipulated to move a nose 60 thereof into the slot and when the syringe is thereafter moved laterally away from the plate the needle cap, which cannot pass through the slot, is left on the cap holder. The cap can be reapplied to the needle by reversing this action. The cap holder includes an end abutment (30) against which the cap can be urged when the cap is reapplied and spring clips 38 for positively holding a cap on the cap holder. Guide members (14a and b) guide the nose of the hypodermic syringe into the slot and a clamp 20 clamps the hypodermic needle-cap handling device to a table.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
288 words
A hypodermic needle-cap handling device for aiding in the removal and reapplication of a cap from and to a hypodermic needle of a hypodermic needle assembly, said hypodermic needle assembly being of a type having a needle attached to a nose of a syringe, said cap, which has a cavity for receiving the needle in a mouth thereof, being attachable to said hypodermic needle assembly by means of friction, said handling device comprising: a thin rigid plate having a slot therein with one end of said slot forming an open mouth, said slot having a width which is larger than said nose of said hypodermic syringe but which is narrower than the width of said cap; a cap holder mounted on one side of said rigid plate adjacent said slot for holding a needle cap that has been removed from a hypodermic needle assembly with the aid of said handling device, said cap holder having a surface extending laterally to said thin rigid plate for holding said needle cap with its cavity mouth being directed towards said slot; whereby a syringe of a hypodermic needle assembly having a cap thereon, can be manipulated to move its nose into said slot of said thin rigid plate with the syringe on one side and the cap on the other side of the plate, said syringe can then be pulled laterally away from said thin rigid sheet while said cap, which cannot pass through the slot, is pulled from the hypodermic needle assembly and left on the cap holder; thereafter, the syringe can be manipulated to pass the needle again through the slot into the cavity mouth of the needle cap to reapply the needle cap to the hypodermic needle assembly.
