Before Using:
1. Check the tube cover and tube body of the vacuum collector. If the tube cover is loose or the tube body is damaged, it is prohibited to use.
2. Check whether the type of blood collection vessel is consistent with the type of specimen to be collected.
3. Tap all blood collection vessels containing liquid additives to ensure that the additives do not remain in the head cap.
Using:
1. Select the puncture site and smoothly enter the needle to avoid poor blood flow.
2. Avoid "backflow" in the process of puncture: in the process of blood collection, move gently when loosening the pulse pressing belt. Do not use an overly tight pressure band or tie the pressure band for more than 1 minute at any time during the puncture process. Do not untie the pressure band when the blood flow into the vacuum tube has stopped. Keep the arm and vacuum tube in the downward position (the bottom of the tube is under the head cover).
3. When the tube plug puncture needle is inserted into the vacuum blood collection vessel, gently press the needle seat of the tube plug puncture needle to prevent "needle bouncing".
After use:
1. Do not pull out the venipuncture needle after the vacuum of the vacuum blood collection vessel has completely disappeared, so as to prevent the tip of the blood collection needle from dripping blood.
2. After blood collection, the blood collection vessel should be reversed immediately to ensure complete mixing of blood and additives.
