Problems solved by technology

[0002] For general medical institutions, it is common and frequent work to conduct blood analysis tests on patients, to understand the bacteria or diseases infected by patients through blood analysis, and to detect whether the physiological functions of the human body are normal. After drawing blood from the patient, the medical staff often need to cover the needle back to the needle head. This action often causes the medical staff to accidentally stab themselves, increasing the possibility of the medical staff being infected with fatal diseases. Therefore, the choice of blood drawing tools is particularly important.
[0003] In addition, since the syringe and the needle are made of different materials, on the one hand, because the needle is a sharp object, it must be recycled separately from the syringe in the recycling of medical waste. Traditionally, the medical staff puts the needle cover back on. It is necessary to twist the needle by hand and place the needle in the recycling bin. This process also puts medical personnel in danger, and it is easy to cause disease infection due to the problem of handling the needle
