First: blood bags are uniform specifications, the specifications of the provinces and cities are different, there are 200, 300, 400 ml, each blood bag has a corresponding anticoagulant and blood preservation fluid, for example, you intend to donate 400 ml of blood, but the weighing of the figures shown on the 400 ml + blood bag + blood bags of anticoagulant and preservation of the total milliliter number of the blood bag, the preservation of the corresponding fluid for each specification is the ratio, to ensure the quality of blood. proportions to ensure the quality of the blood. If there is an imbalance in the ratio, the blood will be directly scrapped and there is no way to apply it to the clinic. Therefore, you don't have to worry at all about whether you will draw too much or what, just rest assured.
Secondly, the issue of how much blood to donate has always been a controversial topic. A lot of friends think that 200 ml is relatively small, 400 ml is afraid that they can not afford, this problem you basically do not have to worry about, why? First of all, as a blood donor, if you are able to participate in blood donation, you must meet all the criteria for blood donation, such as body weight, blood pressure, blood type, liver function, cardiopulmonary function, as well as your mental state. For an adult weighing 110 pounds or so, all the blood in the body is about 4,000 to 5,000 milliliters of blood, and a scientifically sound donation of 400 milliliters of blood can effectively allow your liver and spleen organs to mobilize the stored blood, and thus rapidly increase the amount of blood in the liver and spleen. Scientific and reasonable blood donation of 400 ml can effectively mobilize the blood stored in your liver, spleen and other organs, thus rapidly replenishing your physical energy, and at the same time avoiding the risk of blood transfusion and cross-infection in the clinic; and then, the minimum amount of blood donation in our country is 200 ml, and how much is 200 ml equivalent to? It is equivalent to the total amount of one more menstrual cycle among female friends. And male friends never have the opportunity to lose blood, which means why after people reach middle age, most of them are men with high blood pressure, high blood fat, high cholesterol or fatty liver and other related diseases, they can't help but smoke and drink, work and social pressure, not paying attention to their diet, irregular rest in the process of young to middle age, and some of them also have some genetic history, so especially male friends are able to So especially male friends are able to participate in blood donation, which is beneficial and harmless to themselves, their families and the society.
I hope you will continue to participate in blood donation, thank you!
