Steps for usage:
1) Remove the arterial lancet from the sterile package.
2) Remove the cap of the arterial blood collection needle and put it in a proper position.
3) Pull the needle cap outward.
4) Push the core rod forward to the zero scale line, and then withdraw it to preset the desired scale.
5) The arterial blood collection needle is downward, and the puncture is performed at an angle of 45° to 90°.
6) Fill the sample to the preset scale at arterial pressure.
7) After sample collection, immediately pull out the needle of the arterial blood collection needle and press the puncture point with gauze for at least 5 minutes to prevent bleeding.
Precautions for use:
1) Do not use if the protective cap is loose or comes off.
2) For personal safety, do not reuse the lancet.
3) Do not share the same lancet with others to prevent cross infection.
4) The problem of fixing the blood collection needle: the little finger presses the connecting tube or the tape sticks to one-third of the connecting tube. If conditions permit, the needle tip of the blood collection needle should enter the blood vessel as much as possible.
5) Bullet tube problem: In order to prevent the bullet tube, hold the blood collection tube with one hand and the end of the blood collection needle with the other hand.
6) The problem of uterine bleeding: the cotton swab or the post-needle sticker gently press the puncture point to prevent the occurrence of bleeding.
7) Occasionally, the blood flow rate is very slow during use. It may be that the negative pressure of the vacuum blood collection tube is insufficient, the patient's blood is thick, the blood pressure is low, and the blood vessel wall blocks the needle hole of the blood collection needle.
