Problems solved by technology

During the above process, since the needle has been exposed in the air, the risk of the nurse being stabbed by the needle is relatively high, which is likely to cause infection; and when the blood collection needle is thrown into the sharps storage box, the previously discarded sharps storage box Lancets can also injure caregivers due to needle point orientation

[0004] In order to overcome the above problems, after the blood collection needle is used, the operator puts the traditional blood collection needle on the protective cover again, but this operation is extremely inconvenient, and it is difficult to align the protective cover and the needle, and it is easy to puncture There is a greater risk of infection caused by injuring the nursing staff, and this operation wastes a lot of time for the nursing staff
