  • Pinch valve mechanism for a parenteral infusion system
    Patent number: 4878646
    Abstract: A pinch valve mechanism for a parenteral infusion system is provided which includes a spring-loaded pinch valve. The pinch valve is manually latched to its open position. A bobbin and cam mechanism includes a length of wire which contracts when a current is applied to it. The cam has two positions, one which holds the pinch valve in its open position and one which enables to pinch valve to close. When it is desired to automatically close the pinch valve, a current is applied to the wire. The contraction of the wire moves the cam from its valve open position to its alternate position, permitting the pinch valve to spring closed.
