초록 ▼

The valve is positioned in the left ventricle drain line and includes a check valve which permits flow only away from the heart. A vent valve is located downstream of the check valve to prevent buildup of pressure. In addition, the valve includes an inwardly directed umbrella valve to limit left ven

대표청구항 ▼

A valve for the control of vacuum in a physiological liquid drain line, said valve comprising: a valve body connectible in the drain line between a patient and a suction pump, said body having a flow passage therethrough having an inlet end and an outlet end, a tubular boss on said body, a vacuum vent opening in said body and said boss, said opening extending radially from said passage through said body through said tubular boss to the atmosphere, a perforated flange in said tubular boss, a resilient umbrella valve on the side of said flange toward said passage covering the perforation in said flange to limit the vacuum in said flow passage; walls defining a pressure relief passage in said body extending from said flow passage to the exterior of said body, said walls defining a nipple around said pressure relief passage extending outward from said body; and a tubular elastomeric member on said body engaged on said nipple and covering said pressure relief passage so that when pressure in said flow passage is below atmospheric pressure said pressure relief passage is closed and when pressure in said flow passage is above atmospheric pressure, fluid in said flow passage discharges out of said pressure relief passage through said nipple out from under said tubular elastomeric member.
