Abstract
A pulsed liquid injection device for injection of predetermined dosage volumes of medication at predetermined intervals of time over an extended period is described. A relatively large supply of medication is maintained in a bag under pressure, and metered portions thereof are released at time intervals by an electronically controlled metering device. The metering device includes a simple valve arrangement containing three flexible resilient elements arranged and controlled in such a way as to provide shut off of medication supply in the event of a malfunction, either electrical or mechanical.
