Catheter Assembly

US Patent:
5234410, Aug 10, 1993
Filed:
Oct 23, 1992
Appl. No.:
7/965339
Inventors:
Chad D. Graham - Bell Buckle TN
Rex R. Weeks - Rapid City SD
Assignee:
VLV Associates - East Hanover NJ
International Classification:
A61M 2500
US Classification:
604167
Abstract:
The catheter assembly is provided with a conventional catheter which extends from a hub. In addition, a tube or blunt needle is mounted within the hub coaxially of the catheter and is provided with an elastomeric valve over the open end. The elastomeric valve is formed by a pair of rubber sheaths, each of which has a closed end for sealing the tube against a back flow of blood. The sheaths can be pierced by a needle in order to perform a venipuncture while re-sealing upon removal of the needle. The catheter assembly may also be connected with a male luer connector in a manner to push the sheaths over the tube so as to expose the lumen of the catheter to the connector.
