Problems solved by technology

[0002] There are great problems in the use of blood collection needles: 1) When clinically collecting blood samples from patients, most of them hold syringes to puncture blood vessels to draw blood samples. The surface of the syringe is smooth and easy to slip; The blood will flow back, which will easily bring bacteria into the human body and cause secondary infection; 3. Whether it is injection or recycling, the needle tip may pierce the finger of the person, which is easy to cause infection
