Blood drawing device for hematology analyzer

Abstract

The invention discloses a blood drawing device for a hematology analyzer. The device relates to the medical field, and includes a first blood drawing tube, a first cover plate is arranged at the top of the first blood drawing tube; a dustproof sleeve is arranged in the middle of the top of the first cover plate; a reset spring is arranged in the dustproof sleeve, a pressing column is arranged at the top of the reset spring, a pressing plate is arranged at the top of the pressing column, a hose is arranged at the top of the pressing plate, a second blood feeding needle penetrating into the dustproof sleeve is fixed to the bottom of the hose, and a first cavity is formed in the bottom of the first blood drawing tube. The internal thread and the external thread are matched with each other; the second blood feeding needle is inserted into the first rubber sleeve at the bottom of the first blood drawing tube, meanwhile, the second cover plate is rotated to drive the connecting column to rotate into the first cavity, connection of multiple sets of blood drawing tubes is completed, sampling is facilitated, meanwhile, the phenomenon that the blood feeding needle is polluted is reduced, anduse safety is greatly improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a blood drawing device for a blood cell analyzer. Background technique [0002] Blood cell analyzer, also known as blood cell analyzer, blood cell meter, blood cell counter, etc., is one of the most widely used instruments in hospital clinical testing. With the rapid development of computer technology in recent years, the technology of blood cell analysis has also changed from three groups Turning to five groups, from two-dimensional space to three-dimensional space, and we have also noticed that many of the five classification technologies of modern blood cell analyzers use the same technology as today's very advanced flow cytometers, such as scattered light detection technology, sheath flow Technology, laser technology, etc., when the blood cell analyzer is working, blood needs to be drawn, so many hospitals will introduce a blood draw device for the blood cell analyzer. [0003] However, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that when more samples need to be taken when using the blood drawing device for blood cell analyzers today, the blood drawing blood vessel needs to be replaced, which causes the blood sending needle to be easily polluted, which not only affects the detection effect but also affects the blood drawer. The health of the body, and at the same time it is inconvenient to control the start and suspension of blood drawing, which greatly reduces the scope of its use. A blood drawing device for blood cell analyzer is provided.
