1) Remove the arterial blood collection needle from the sterile packaging.
2) Remove the arterial blood collection needle cap and place it in a proper position.
3) Move the needle cap outward.
4) Push the mandrel forward to the zero mark line and pull back the preset to 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 with a preset scale under arterial pressure.
7) After the sample is collected, 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.
Attention:1) Do not use if the protective cap is loose or loose.
2) For personal safety, do not reuse the lancet.
3) Do not share the same lancet with others to prevent cross-infection.
4) Fixation of the blood collection needle: The small thumb presses the tube or the tape sticks to one third of the tube. If the condition permits, the needle tip of the blood collection needle enters the blood vessel as much as possible.
5) The problem of the elastic tube: In order to prevent the elastic tube, the blood collection tube is taken in one hand, and the tail end of the blood collection needle is held in one hand.
6) Bleeding problem: gently press the puncture point after the cotton swab or needle to prevent the occurrence of blood clots.
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, the blood pressure is low, and the blood vessel wall blocks the needle of the blood collection needle.
