A microblood collection tube is a medical device used to collect a small amount of blood samples. It is mainly used in pediatrics, newborns, anemic patients or people who need frequent tests, reducing the amount of blood collected while meeting the testing requirements. Its core advantage lies in alleviating patient discomfort, reducing the risk of anemia, and ensuring the accuracy of the test. It is usually composed of parts such as the tube body, additives, and labels, and the corresponding type should be selected according to the test items.
Definition and Application:
The capacity of microblood collection tubes is usually 0.5 to 2 milliliters, which is much lower than that of conventional blood collection tubes (3 to 10 milliliters). They are suitable for scenarios where the blood collection volume needs to be controlled, such as:
Infants, toddlers or newborns: Their blood vessels are small, making blood collection difficult.
2. Anemic or critically ill patients: Avoid aggravating the condition due to excessive blood collection;
3. Frequent testing requirements: such as blood glucose monitoring, blood routine re-examination, etc.
Advantages and Applicability:
1. Reduce blood collection volume: Lower the pain and anemia risk for infants, the elderly and other groups;
2. Easy operation: Compatible with micro-blood collection needles or peripheral blood collection (fingertips, heels);
3. Precise detection: Pre-installed additives ensure sample quality and prevent hemolysis or coagulation.
4. Environmental protection and conservation: Reduce medical waste and lower testing costs.
Structure and Material:
1.Tube body: Mostly transparent plastic or glass, marked with volume scales for easy observation of blood volume.
2.Additives: Pre-set anticoagulants (such as EDTA, heparin) or coagulant accelerators according to the testing requirements;
3.Label: Indicates the purpose, validity period and type of additive;
4.Lid color: International standard code (e.g., purple lid is used for blood routine).
