Abstract

The invention relates to an injection device, in particular to a portable reagent injection device for a clinical laboratory. The invention provides a portable reagent injection device for a clinical laboratory, which integrates liquid adding, valve control and pushing. A portable reagent injection device for a clinical laboratory comprises a shell, a needle tube, an extrusion mechanism, a closing mechanism and a pushing mechanism, the needle tube is arranged on the upper portion of the shell, the extrusion mechanism is arranged in the shell, the closing mechanism is connected between the extrusion mechanism and the shell, and the pushing mechanism is connected among the closing mechanism, the extrusion mechanism and the shell. According to the invention, the pushing mechanism is moved upwards by people, so that the first piston rod moves upwards, the first spring is compressed, a reagent flows upwards into the needle tube, and the pushing effect is achieved.

Description

technical field [0001] The present invention relates to an injection device, in particular to a portable reagent injection device for laboratory use. Background technique [0002] The laboratory is mainly responsible for the detection of various human and animal specimens including wards, outpatient and emergency patients, various physical examinations, and scientific research. The staff needs to inject reagents into test tubes for testing every day. Injecting the drug into the syringe, and then injecting the reagent into the test tube, this injection method requires repeated operations. Therefore, an injection device needs to be designed. [0003] Therefore, it is particularly necessary to design a portable reagent injection device for laboratory departments that integrates liquid addition, valve control and push, so as to solve the problems existing in the prior art. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a portable reagent ...
