A multi-angle tumor injector

Abstract

The invention discloses a multi-angle tumor drug injector, and belongs to the technical field of medical supplies. The multi-angle tumor drug injector comprises a push rod, wherein the left side of the push rod is connected with an air tube in a plugging manner; a dial is arranged on the outer wall of the air tube; a positioning slot is formed in the outer wall of the dial; the left side wall of the air tube is connected with a connection hole in the plugging manner; the right end of the air tube is movably connected with a drug tube; a positioning pin connected with the positioning slot is arranged at the top of the drug tube. The multi-angle tumor drug injector enables medical staff to adjust an angle according to the dial under the action of the positioning pin and the dial; after the angle is adjusted, the positioning pin is used for fixing the dial and the drug tube to achieve an effect of fixing the angle, so that the operation of the medical staff is facilitated, and pain of a patient is relieved; the drug tube is connected with the air tube through a shaft sleeve, so that when being subjected to angle adjustment, the drug tube can rotate more smoothly by the use of a connection pin shaft, and no mechanical vibration is caused.

Description

Technical field [0001] The invention relates to the technical field of medical supplies, in particular to a multi-angle tumor injection device. Background technique [0002] In medical treatment, a syringe is often used to inject the human body to achieve the effect of removing the patient. Injecting drugs is very painful for humans. Sometimes improper adjustment of the angle of the syringe will increase the pain many times. Therefore, a new type of pain is needed. Syringe to avoid this kind of injury. For example, Chinese Patent Application No. 201420728129.X is a multi-angle tumor injecting device, which includes a syringe, a plug arranged below the syringe, a needle inserted on the plug, and a lower end of the needle. The needle hole, the piston slidably inserted in the needle cylinder, the piston rod fixed on the piston, and the pressing head arranged at the head end of the piston rod, and also include a number of sliders arranged on the needle, arranged inside the needle and...
