| Message: | The vacuum blood collection device consists of three parts: vacuum blood collection tube, blood collection needle (including straight needle and scalp blood collection needle), and needle holder. Vacuum blood collection tube is the main component, mainly used for blood collection and storage. A certain amount of negative pressure is preset in the production process. When the blood collection needle punctures into the blood vessel, the blood automatically flows into the blood collection tube due to the negative pressure in the blood collection tube ; At the same time, various additives are preset in the blood collection tube, which can fully meet the clinical multiple comprehensive blood tests, safe, closed, and convenient for transportation.
Vacuum blood collection tubes are generally divided into the following types:
1. Dry empty tube without additives: The inner wall of the blood collection tube is evenly coated with the agent (silicone oil) to prevent wall hanging. It uses the principle of natural blood coagulation to coagulate the blood. After the serum is naturally precipitated, it is centrifuged for use. Mainly used for serum biochemistry (liver function, kidney function, myocardial enzymes, amylase, etc.), electrolytes (serum potassium, sodium, chloride, calcium, phosphorus, etc.), thyroid function, drug testing, AIDS testing, tumor markers, serum immunity learn.
2. Coagulation accelerator tube: the inner wall of the blood collection tube is evenly coated with silicone oil to prevent wall hanging, and coagulant is added. The coagulant can activate the fibrinase, so that the soluble fibrin becomes insoluble fibrin aggregates, and then forms a stable fibrin clot. If you want to get the result quickly, you can use the coagulation tube. Generally used in emergency biochemistry.
3. Blood collection tube containing separation gel and coagulant:
4. Blood collection tube containing anticoagulant in the tube: |
