Vacuum blood collection tubes are medical consumables used for collecting blood wave samples in clinical Settings, mainly in hospitals, clinics and other medical institutions. Its shape is similar to a slender transparent tube. The interior is pre-evacuated to a vacuum state and it automatically sucks in blood by the principle of negative pressure. This design avoids the trouble of manual drawing with traditional syringes during blood collection, which is not only convenient for medical staff to operate but also reduces the possibility of blood contamination. The opening of the blood collection tube is equipped with a rubber sealing plug that can be closely connected to the dedicated blood collection needle, ensuring that the entire blood collection process is closed and sterile. Modern vacuum blood collection tubes are generally made of plastic, which is lighter and less likely to break compared to the early glass tubes. Various anticoagulants or coagulant accelerators added inside the tubes can preserve blood samples according to different testing requirements. For example, the tubes with purple caps contain the anticoagulant EDTA and are suitable for routine blood tests, while the tubes with yellow caps are used for biochemical tests. This standardized design has significantly enhanced the accuracy and efficiency of medical testing.
The applicable population of vacuum blood collection tubes mainly includes the following categories:
1. Patients requiring blood tests: Used for diagnosing diseases, evaluating treatment effects or monitoring changes in the condition.
2. For those undergoing health check-ups: Blood samples will be collected during routine physical examinations to test basic indicators such as liver function and blood sugar.
3. Preoperative examination population: Important physiological parameters such as coagulation function and infection indicators are evaluated before the operation.
4. Pregnant women: Monitor key pregnancy indicators such as hemoglobin and blood sugar during prenatal check-ups.
5. Patients with chronic diseases: For instance, those with diabetes need to regularly monitor their blood sugar control.
