Problems solved by technology

[0003] When in use, fix the blood collection needle on the front end of the outer cylinder of the needle holder, and perform venipuncture, insert the vacuum blood collection needle into the back end of the needle holder, and make the rear edge of the blood collection needle penetrate into the rubber plug of the vacuum tube. , draw the blood into the blood collection tube; when the blood collection is completed, the medical staff need to put the protective sleeve back on the blood collection needle again, and then rotate the needle body to remove the blood collection needle from the needle holder and place it on the blood collection needle. Discarded in the waste box, during this operation, it is easy to have the chance of finger pricking by the needle point, causing the risk of infection or transmission of blood-borne diseases
