Abstract

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.

Description

technical field [0001] The invention relates to the technical field of drug injection, in particular to an automatic pulse injection device for arterial intervention chemotherapy drug injection. Background technique [0002] Arterial interventional chemotherapy is a chemotherapy method in which the catheter is superselectively placed in the blood supply artery of the tumor under the guidance of a guide wire. The local drug concentration is high, the systemic side effects are few, and the chemotherapy effect is good. Taking retinoblastoma, the most common intraocular malignant tumor in children, as an example, superselective interventional chemotherapy of ophthalmic artery was carried out, and a 0.34mm microguide wire was used to introduce a 0.57mm microcatheter into the ophthalmic artery with a diameter of less than 1mm, which increased the local drug concentration by 14 times, the dosage is reduced by 90%, which significantly improves the eye protection rate of children and...
