What are the steps to use the lancet?




Steps for usage:
1) Take out the arterial blood sampling needle from the sterile package.
2) Remove the cap of the arterial blood sampling needle and put it in a proper place.
3) Flip the needle cap outward.
4) Push the mandrel forward to the zero scale line and withdraw the preset to the required scale.
5) The arterial blood sampling needle is downward, and the puncture is performed at an angle of 45° to 90°.
6) Fill the sample with the preset scale under arterial pressure.
7) After the sample is collected, immediately pull out the arterial lancet needle and press the puncture point with gauze for at least 5 minutes to prevent bleeding.

Precautions for use:
1) Do not use the protective cap if it is loose or detached.
2) For personal safety, please do not reuse the lancet.
3) Do not share the same lancet with others to prevent cross-infection.
4) The problem of lancet fixation: the little finger presses the connecting tube or the tape sticks to one-third of the connecting tube. If possible, the lancet tip enters the blood vessel as much as possible.
5) Bullet tube problem: In order to prevent the tube from collapsing, hold the blood collection tube in one hand and the end of the blood collection needle in the other hand.
6) Bleeding problems: Use cotton swabs or post-needle stickers to gently press the puncture point to prevent bleeding.
7) Occasionally, the blood flow rate is very slow during use. It may be that the vacuum blood collection tube has insufficient negative pressure, the patient's blood is thick, and the blood pressure is low, and the blood collection needle hole is blocked by the blood vessel wall.
