Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a vacuum blood collection device. Background technique [0002] The blood test generally takes venous blood. Except for the special requirements, the venous blood test generally requires blood to be drawn in the morning. The results of some experiments taken have interfered. If you are an inpatient, you should have your blood drawn by a doctor or nurse in a relatively stable state. The skin at the blood draw site should be cleaned as much as possible before the blood draw. The amount of blood drawn depends on the different contents of the test and the number of items. The amount of blood drawn is generally 2-20 ml, and the maximum will not exceed 50 ml. Vacuum blood collection tube is a kind of vacuum negative pressure blood collection tube. The extensive use of automated instruments and the preservation of blood put forward higher requirements for the stability of...
