The blood collection used in the blood station are strictly sterilized disposable medical equipment, must meet the requirements of the national standards; after the use of blood bags, needles and other medical waste in strict accordance with the provisions of the unified treatment, centralized destruction, will not be reused, so donate blood will not be infected with disease.
Expanded Information:
There are two main types of blood donation: whole blood (six-month intervals) and component blood (14-day intervals; the intervals required may vary from one donation site to the next, so please consult with the donor before visiting). Whole blood donations can be made at blood collection points (blood donation centers and blood donation trucks) in most cities and counties.
And donating component blood refers to the act of healthy citizens collecting and separating a component of human blood through a blood cell separator, and the donated component blood can be platelets, granulocytes, plasma or hematopoietic stem cells. Until 2015, it was more common to donate single platelets in China. The general donation of component blood can only be donated at municipal central blood stations and blood centers.
Because the donation of component blood requires a more spacious environment and specialized collection equipment, there are high requirements for the power of the collection equipment and the comfort of the process, and it is generally collected only when clinically necessary. Therefore, you should bring your ID card and other valid documents to each machine blood collection point and make an appointment to donate machine-collected component blood as scheduled.
