Abstract

The invention discloses a drug injection device which comprises a catheter component, an injection head and a handle. The catheter component comprises an outer sleeve, a drug feeding pipe and a filler, the inner side of the outer sleeve is filled with the filler, a catheter channel is formed in the middle of the filler, the drug feeding pipe is connected on the inner side of the catheter channel in a sleeving manner and slidably connected with the inner wall of the catheter channel, one end of the catheter component is connected with the injection head, and the other end of the catheter component is connected with the handle. According to the drug injection device, when a drug is injected into a cerebral ventricle, an injection area of the drug is widened, so that the drug is more uniformly diffused, treatment of a patient can be facilitated, biopsies of the cerebral ventricle of the patient can be achieved, the patient is conveniently treated by medical staff, and the pain of the patient is prevented when biopsy is implemented for the patient again.

Description

technical field [0001] The invention relates to the technical field of drug injection, in particular to a drug injection device. Background technique [0002] Intraventricular injection (intracerel}ral ventricle injeciicn) injects drugs directly into the ventricles of the brain. The chronic experiment must first bury the cannula in the human brain, the end of the tube is about 1 mm away from the wall of the lateral ventricle, and fix it on the sub-skull. [0003] The existing intraventricular injection device has only one injection tube, which results in a small area of ​​drug action during drug injection, and the diffusion effect is uneven. The existing injection tube does not have the function of biopsy sampling. After drug injection, an appropriate amount of brain cannot be taken out. The tissue fluid was tested. To this end, we propose a drug injection device. Contents of the invention [0004] The purpose of the present invention is to provide a drug injection devi...
