Problems solved by technology
[0002] Clinically, due to the high frequency of use of blood collection needles by medical staff, it is inevitable that they will accidentally pierce the medical staff themselves. Due to the complicated situation of the blood collection personnel, if the collected blood contains highly infectious and difficult to cure pathogens such as AIDS and hepatitis B, It will cause a great security threat to the safety of medical staff, so it is necessary to improve the structure of blood collection needles in the prior art to improve the safety of use of blood collection needles
