How to use a single-use phlebotomy needle?
Instructions:
1. After routinely disinfecting the blood collection site, tear off the lancet packaging bag, take out the lancet and remove the sheath on the lancet.
2. The handle of the blood collection needle is pierced into the venous blood vessel at an angle of 25°C. At this time, blood can be seen in the connecting rubber tube.
3. Insert the cork puncture needle (do not remove the latex sheath) into the vacuum tube, the preset vacuum in the tube will make the blood of the required blood flow into the tube, and you can also press the filling on the sticker. Line control the amount of blood collection.
4. After the first tube is collected, pull out the cork and puncture needle and then pierce another vacuum tube. Repeated operations like this can achieve one-needle multi-tube blood collection.
5. To ensure the correct mixing of the blood and the additives in the tube, gently invert the vacuum tube five to eight times immediately after sampling. When the last sample is about to be completed, the needle is withdrawn from the vein (negative pressure in the tube can draw the remaining blood sample in the connecting hose into the tube).
6. After blood collection, put the used lancet into the trash can.
