Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a side-suction upright anti-hemolysis vacuum blood collection tube.
Background
With the rapid development of medical technology, blood routine tests are widely applied as an auxiliary means for disease diagnosis, and the vacuum blood collection tube is a necessary medical instrument for collecting blood samples. The clinical commonly used vacuum blood sampling tube generally comprises a tube body and a sealing plug, different vacuum degrees are pre-pumped in the tube body during production, and a blood sample is quantitatively collected by utilizing a negative pressure principle during use.
However, in the process of collecting blood, the negative pressure in the conventional vacuum blood collection tube is often large at first, when the blood is subjected to large negative pressure suction, the blood can be rapidly sprayed into the blood collection tube, and the blood can collide with the bottom wall of the blood collection tube or the blood which enters the blood collection tube, so that red blood cells are broken, and the probability of blood hemolysis is increased; the conventional vacuum blood collection tube is adjusted to have good vacuum degree in the tube during production, only quantitative blood samples can be extracted, and certain limitations are realized; and if the conventional vacuum blood collection tube is placed for a long time, the negative pressure in the tube can be gradually reduced, so that the finally collected blood volume is reduced.
Disclosure of Invention
The invention aims to provide a side-suction upright anti-hemolysis vacuum blood collection tube, which solves the problem that the conventional vacuum blood collection tube is easy to hemolyze.
The technical purpose of the invention is realized by the following technical scheme:
