Common sense of unpaid blood donation
How much do you know about unpaid blood donation? Let's answer one by one through the following short film ↓↓↓
Is blood donation harmful to health?
The total blood volume of the normal human body accounts for about 8% of the body weight. A person with a weight of 50kg has about 4000ml of blood. The blood that really participates in circulation only accounts for 70% - 80% of the total body blood volume, and the rest is stored in "human blood banks" such as liver and spleen. When the human body loses blood, the stored blood will be released and replenished at any time. After blood donation, the lost water and inorganic salts are replenished by the infiltration of tissue fluid into blood vessels within 1-2 hours; The lost plasma protein is supplemented by the accelerated synthesis of the liver. Blood donation will stimulate the hematopoietic function of the human body and promote blood metabolism.
One time blood donation 200ml
Or 400 milliliters?
According to the Blood Donation Law of the People's Republic of China, the amount of blood collected by blood stations for blood donors each time is generally 200 ml, but not more than 400 ml. A blood donation of 200ml is less than 5% of the total blood in the body. Due to the small amount, it does not touch the neuroendocrine regulation system in the body. If you donate 400 ml of blood at a time, you will be able to touch the regulating system in the body, promote the release of blood temporarily stored in the liver, spleen and other organs to participate in blood circulation, stimulate the hematopoietic function of bone marrow, and promote the regeneration of fresh blood.
What should be paid attention to before and after blood donation?
When donating blood, you need to bring your valid ID card so as to establish a free blood donation file for you, and provide a basis for you and your family to use blood and apply for reimbursement according to regulations in the future. Try to eat light food before blood donation to avoid empty blood donation. Avoid bending and squatting immediately after blood donation, and do not take strenuous exercise and work hard within 24 hours.
