Drug delivery device for medical oncology

Abstract

The invention provides a drug delivery device for medical oncology, which includes a clip, a shrapnel, a drug delivery tube and a drug delivery box, and also includes a gasket, a baffle, an upper piston, a lower piston and a drug suction box. The two clips are arranged in the limit hole of the baffle, the upper surface of the center of the shrapnel is provided with a push rod, the other end of the push rod is connected with the upper piston in the medicine box, and the push rod is provided with a handle. The two ends of the medicine box are communicated with the medicine head through the medicine tube, and the lower surface at the center of the shrapnel is provided with a pull rod, which is connected with the lower piston in the medicine suction box, and the opening of the medicine suction box communicates with the medicine suction head. The beneficial effects of the present invention are: simple structure, easy to use, adopt double piston structure, can spray medicine conveniently, and recover the medicine liquid after action in time, so the treatment effect on tumor part is good, and non-tumor part does not cause damage, At the same time, the clip is used to fully expand the tumor site to ensure that the drug solution is directly sprayed on the tumor tissue, the administration position is accurate, and the treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug delivery device for medical oncology. Background technique [0002] The current method of tumor treatment is mainly to control the treatment by taking related drugs, but this method has a long cycle of medication, and because the drug is absorbed through the digestive system instead of directly targeting the lesion of the medical tumor, it will often work. It is slow and the control effect is not obvious, thus requiring long-term treatment, which increases the burden on the patient and brings inconvenience to the patient. Contents of the invention [0003] The invention provides a drug delivery device for medical oncology, which is simple in structure and easy to use. It adopts a double-piston structure, can spray medicine conveniently, and recovers the medicine liquid after action in time, so it has good therapeutic effect on tumor parts and good treatment effec...
