About disposable lancets

1. Operation error,
When the needle is pulled out, when there is still 0.5 ml from the prescribed scale, first pull out the venous blood collection needle, and then pull out the tube and plug the puncture needle! The reason why the venipuncture needle is pulled out first is that there is still a negative pressure of 0.5 in the tube, and about 0.3 ml of the remaining blood in the blood collection tube can be sucked into the tube, so that it will not remain and avoid blood leakage.
(Every time you change the tube, the needle is pulled out at a distance of about 0.5 ml from the specified scale. For example, a 3 ml negative pressure tube will generally adjust the negative pressure to 3.2 ml. You can basically ensure 3 ml of blood by pulling the needle at about 2.7 ml. , Do not wait for the tube to be full before pulling out the needle, because if the rebound is not smooth, the blood pressure in the human body is greater than the atmospheric pressure and the blood will leak)
2. If the operation is correct, generally good quality pipes such as BD or Yangpu can basically ensure smooth rebound without blood leakage and pollution of the environment, and ensure the airtightness of the system, but it is not 100% able to return smoothly. Bombs, individual tubes will also leak blood.
3. The vacuum blood collection system is sealed with negative pressure, the blood collection needle is sterile, and aseptic operation can ensure the safety of the patient. This conclusion is not what I said, but what the WHO said.
