How to use disposable vacuum venous blood collection tube

The method of using the disposable vacuum venous blood collection tube is as follows:

1. Open the package and check whether the vacuum venous blood collection tube and vacuum blood collection device are intact.

2. Tear off the sealing strip of the vacuum venous blood collection tube and connect the vacuum blood collector and the vacuum venous blood collection tube tightly.

3. Gently loosen one end of the needle to allow the needle to extend from the hose, and then insert the needle into the vein to a depth of about 2.5-5cm.

4. Loosen the clamp on the vacuum blood collection device and the blood will flow into the vacuum venous collection tube by itself.

5. When the preset number of drops reaches or approaches the required blood collection volume, use hemostatic forceps or your hand to gently clamp the clamp on the vacuum blood collector to stop the blood from flowing in.

6. Remove the needle, close the connection port, gently pull the hose several times to remove air bubbles in the blood, and then clean the connection port.

7. After using the disposable vacuum venous blood collection tube, clean and dry the skin and discard it as required.

Please note that to ensure your health, please follow proper procedures when collecting blood samples.
