The invention discloses an automatic pulse-type pushing-
injection device for arterial interventional
chemotherapy drug injection. The automatic pulse-type pushing-
injection device includes a processor, a pushing-
injector, a pulser, a
syringe, and a flow restrictor. The processor is electrically connected with a
sphygmomanometer and an electrocardiogram monitor, the
syringe is installed on the pushing-
injector, a volume detection device is installed in the
syringe, a
catheter is fixedly connected to the output end of the syringe, a three-way tube is installed in the middle of the
catheter, andthe pulser includes a motor and an impulse valve. The impulse valve is driven by the motor, the impulse valve is installed on the three-way tube, the flow restrictor is installed at the end, away fromthe syringe, of the
catheter, the flow restrictor is a one-way valve, and the motor, the pushing-
injector and the volume detection device are all electrically connected to the processor. The automatic pulse-type pushing-
injection device has the beneficial effects that while automatic pulsed
drug delivery is realized, the problems of insufficient pushing-injection strength and
arterial blood reflux can be solved, the manpower of doctors is liberated, and the operation efficiency is improved.
