Abstract
A method of making a self-capping needle and catheter assembly (10) includes placing a needle hub (16) and cap (34) on a pin with the pin extending through the passageways (24, 35) thereof. Two sheets of polymeric material (62) are placed about the hub (16) and the cap (34) with their edges welded together producing a sleeve (64) connected between the hub (16) and the cap (34). The sleeve (64) is then permanently stretched to a predetermined length. The cap (34), hub (16) and sleeve (64) are then placed on a needle (28) and the cap (34) is moved against the hub (16) folding the sleeve (64) therebetween for reception of the catheter assembly (14).
Claims11
A method of forming self-capping intravenous needle assemblies (10) adapted to receive a catheter assembly (14) releasibly connected to the needle assembly (10), the method including the steps of:
- aligning the passageways (24, 35) of a hub portion (16) and a cap (34) of the needle assembly (12) longitudinally with one another,
- securing a sheet of material (62) to and extending between the hub portion (16) and cap (34),
- sealing the edges of the sheet of material extending between the hub portion (16) and cap (34) producing an enclosed sleeve (64),
- extending a needle (28) through the passageways of the hub portion (16) and cap (34), and moving the cap (34) and hub portion (16) adjacent one another to fold the sleeve (64) therebetween for storing until use of the needle assembly.
