Needleless access device.

摘要

The present invention relates to a needleless access device (10) and method of using the device. The needleless access device (10) has a housing (12) having an inlet opening (6) and an outlet opening (8) and a channel (15) formed therethrough. Moveably friction fitted in the channel (15) adjacent the inlet opening (6) is a piston (18). The piston (18) is biased upwardly by a stretchable element (20). The stretchable element (20) allows the top of the piston (18) to be depressed by a syringe to a level adjacent internal flow channels (28) to permit injection and aspiration of fluids through the device.
