Vacuum blood collection tubes' classification

Views: 0     Author: Site Editor     Publish Time: 2022-08-01      Origin: Site

The vacuum blood collection device consists of three parts: a vacuum blood collection tube, a blood collection needle (including a straight needle and a scalp blood collection needle), and a needle holder. The vacuum blood collection tube is its main component, which is mainly used for blood collection and preservation. A certain amount of negative pressure is preset in the production process. When the blood collection needle is punctured into the blood vessel, due to the negative pressure in the blood collection tube, the blood automatically flows into the blood collection tube. In the blood collection tube; at the same time, various additives are preset in the blood collection tube, which can fully meet a number of comprehensive clinical blood tests, and is safe, closed and convenient for transportation.

Vacuum blood collection tubes's classification

1. Dry empty tube without additives: The inner wall of the blood collection tube is evenly coated with a drug (silicon oil) to prevent wall hanging. It uses theNo Additive Serum Blood Collection Tube manufacturer - Smail principle of natural blood coagulation to coagulate blood, and after the serum is naturally precipitated, it is centrifuged for use. Mainly used for serum biochemistry (liver function, kidney function, myocardial enzyme, amylase, etc.), electrolytes (serum potassium, sodium, chloride, calcium, phosphorus, etc.), thyroid function, drug testing, AIDS testing, tumor markers, serum immunity learn.

2. Coagulation tube: The inner wall of the blood collection tube is evenly coated with silicone oil to prevent wall hanging, and a coagulant is added at the same time. Coagulants can activate fibrin, turn soluble fibrin into insoluble fibrin aggregates, and then form stable fibrin clots. If you want to get results faster, you can use coagulation tubes. Generally used for emergency biochemistry.

3. Blood collection tube containing separation gel and coagulant: the tube wall is siliconized and coated with coagulant to accelerate blood coagulation and shorten the test time. Separation gel is added in the tube. Separation gel has good affinity with PET tube, and it does play a role in isolation. Generally, even in ordinary centrifuges, the separation gel can separate the liquid components (serum) and solid components (blood cells) in the blood. Separate completely and accumulate in the tube to form a barrier. No oil droplets are produced in the serum after centrifugation, so it does not clog the machine. Mainly used for serum biochemistry (liver function, kidney function, myocardial enzyme, amylase, etc.), electrolytes (serum potassium, sodium, chloride, calcium, phosphorus, etc.), thyroid function, drug testing, AIDS testing, tumor markers, serum immunity learn.
