ABSTRACT:
A flow system for infusing a fluid such as blood from a storage reservoir into the human body includes a hand-operated pump for increasing the flow rate of the fluid through the system when required. The pump includes a duckbill-type valve assembly user-conditionable to an open position wherein fluid can pass freely through the valve and air trapped in the housing of the pump can be purged upline to the reservoir, and to a closed position wherein reverse flow of fluid in the system is prevented during operation of the pump.
