Key features:
A vacuum blood collection tube is a clinical testing device that is mainly used to collect blood samples. Its main function is to make the blood flow into the tube automatically through the principle of negative pressure, which is convenient for the collection and preservation of blood samples.
Vacuum blood collection tubes are usually made of glass or plastic and contain a certain amount of anticoagulants and additives inside. Anticoagulants prevent blood clotting and keep the blood in a liquid state, thus guaranteeing the accuracy of the blood samples collected. Additives can help stabilize blood components and prevent changes in blood samples during collection and transportation.
Vacuum blood collection tubes are very easy to use. To collect a blood sample, the health care provider simply connects one end to the lancet, inserts the other end into the patient's vein or artery, and waits for the blood to automatically enter the tube. Once the blood is in the tube, the health care provider can remove the lancet and seal the tube so that the blood can be sent to a lab for testing.
One of the advantages of vacuum blood collection tubes is that they reduce the risk of contamination and cross-contamination. Because the blood enters the tube automatically under negative pressure, medical staff do not need to touch the blood directly, reducing the likelihood of infection. In addition, vacuum blood collection tubes can also reduce oxidation and contamination of blood samples, maintaining the stability of blood samples.
In general, vacuum blood collection tube is a convenient, safe and accurate clinical examination device. Its main function is to automatically collect blood samples and maintain the stability of the blood through the principle of negative pressure. Its use can reduce the risk of contamination and cross-contamination and improve the accuracy of blood samples.
