Abstract
A pulsed liquid injection device for injection of predetermined doses of medication at predetermined intervals of time is described. A bag containing medication is maintained under pressure and is connectable via a three way valve, operable by means of an electronic timing device, to a second pressurized metering container which is smaller than the bag containing the medication. The pressure in the bag is higher than that of the metering device and the metering container is always at a pressure required for injection. The timing device operates the valve at intervals to (a) charge the metering container from the bag and (b) inject the charge in the metering container into the patient. The valve includes a blanking device to eliminate the possibility of injecting the patient directly from the bag.
