Vacuum Blood Sampling Collection Needle

Blood sampling refers to the process of taking blood samples through veins and arteries by medical personnel for testing or related needs. Blood collection is undertaken by medical staff and personnel trained in blood collection technology, and cannot be employed without special training; the proficiency of blood collection technology is directly related to the quality of blood and the health of the blood donor, so every blood collection staff must be proficient Blood collection technology. When collecting blood, place the donor's arm flat, tie a tourniquet or blood pressure meter about 5cm above the elbow socket, and keep the pressure at 5.3～8.0kPa (40～60mmHg). Choose the median elbow vein that is thick, full, flexible, and not easy to slide, followed by the expensive vein; because the cephalic vein is easy to slide, it is only used when the former is not easy to touch. Existing blood sampling needles are mostly disposable products, which wastes resources. At the same time, the protection effect of sampling needles is poor, and they are easily damaged by external collisions.
