Precautions for disposable vacuum venous blood collection tubes

When using disposable vacuum venous blood collection tubes, please note the following:

1. Before collecting venous blood, inject 3 to 5 ml of normal saline into the vacuum venous blood collection tube.

2. When collecting venous blood, avoid shaking or hitting the blood collection tube vigorously to avoid destroying the vacuum state and causing blood coagulation.

3. After collecting venous blood, it should be sent for testing as soon as possible to ensure the accuracy of the test results.

4. After blood collection, you need to press the blood collection site with a cotton ball or sterile gauze for 3 to 5 minutes to avoid local bleeding or bruising.

5. The plastic tube in the venous blood collection tube may affect the test results, so you need to read the instructions carefully before use, or consult a professional.

6. When using disposable vacuum venous blood collection tubes, choose products produced by regular manufacturers to avoid using counterfeit and inferior products that may cause infection.

7. When using disposable vacuum venous blood collection tubes, avoid reuse to avoid cross infection.
