Problems solved by technology

The filter for the syringe can filter the medicinal liquid and is detachably connected with the syringe. In the invention, a filter is set at the position of the needle tube to filter through the filter. However, due to the small section of the needle tube, the flow rate that the filter can filter is limited. And easy to clog, difficult to clean

Abstract

The invention discloses an injector. According to the injector, the injection amount of a syringe needle is controlled, the syringe needle is supported, and medicine liquid is filtered through a filter net cover of the bottom. The syringe needle can be supported in the injection process, and the syringe needle is prevented from falling off or being further injected in skin. The injector is characterized in that the two ends of a cylinder are of open structures respectively, a bottom end cover is detachably arranged at the bottom of the cylinder and clamped to the bottom of the cylinder, and afront end cover is detachably arranged at the top of the cylinder and clamped to the top of the cylinder; two through holes are formed in the front end cover, a piston plate is arranged in the cylinder and fits the inner wall of the cylinder, and one end of one of two push rods is connected with the piston rod separately; the other end of one of the two push rods penetrates through the two throughholes in the front end cover, a fixing rack is connected with the other end of one of the two push rods and composed of a middle connection block and two connection plates, and the two connection plates are placed at the two sides of the middle connection block respectively and correspondingly connected with the other end of one of the two push rods respectively.

Description

technical field [0001] The syringe of the present invention relates to a syringe for injecting medicine in medical treatment and belongs to the field of medical equipment. In particular, it relates to a syringe that controls the amount of needle penetration, supports the needle, and filters the liquid medicine through a filter net cover arranged at the bottom. Background technique [0002] At present, in the medical process, syringes are often used for drug injection, so that patients can take drugs and facilitate treatment. The existing syringes have various structures. Human body, but when injecting, it is necessary to artificially control the amount of the needle inserted, and the needle is not supported during the pushing process, and it is easy to fall off when the patient retracts in pain. Some of the precipitation in the drug will be injected, and some will be blocked in the needle. It affects the continuation of the injection action, and the existing one-sided openi...
