<p>A valve assembly is described for closure of resilient tubes and protection of the ends of such tubing from contamination when the valve is in its closed position. The valve assembly is fabricated from two trough-like members which are connected by a linkage having bi-stable characteristics to facilitate one-handed operation. The assembly is particularly useful when employed at the end of drainage bag outlet tubes in hospital applications, where the likelihood of contamination of the tube end must be minimized.</p> |
