Self-capping syringe assembly with one-way valve

摘要

A syringe assembly is disclosed which includes a syringe body defining a fluid reservoir, a plunger assembly including a plunger rod and a sealing member supported on the plunger rod, and a luer cap releasably secured to a distal end of the syringe body. The luer cap includes a luer-type connector member and a fluid outlet. A one way valve is supported within the fluid outlet of the luer cap to prevent flow from the fluid outlet back into the fluid reservoir of the syringe body.

1. A self-capping syringe assembly comprising:
a syringe body defining a fluid reservoir and an outlet opening; a plunger assembly including a plunger rod and a sealing member supported on a distal end of the plunger rod; a luer cap including retention structure to releasably secure the luer cap to a distal end of the syringe body, the luer cap including a luer-type connector member adapted to engage an I.V. catheter assembly and defining a fluid outlet positioned to communicate with the outlet opening of the syringe body; and a one-way valve positioned within the fluid outlet of the luer cap, the one way valve being configured to allow fluid to flow from the outlet opening through the fluid outlet but to prevent fluid flow from the fluid outlet back into the outlet opening.
