June 14th is
The 17th "World Blood Donor Day"
Blood donation is a noble act that saves lives. Life is precious, and health and safety are more important. It is necessary to ensure the need and safety of medical clinical blood use, as well as to protect the health of blood donors and blood users. The necessary scientific knowledge is necessary to donate blood scientifically and save lives with safe blood. Today, we will talk about the questions in blood donation that make everyone wonder.
Can I eat before donating blood?
Before donating blood, it is recommended that you first understand the blood donation requirements and blood knowledge, eliminate tension, understand the situation of unsuitable blood donation, and ensure blood safety and the health of the blood donor.
The day before and the day of blood donation can be eaten as usual, but a light diet should be appropriate. Do not drink alcohol, take medicine, do not exercise vigorously, ensure adequate sleep, and keep yourself in a good physical and mental state.
What should I pay attention to after donating blood?
After blood donation, when the lancet is pulled out, follow the instructions of the lancet nurse and compress the eye of the lancet evenly for more than 5 minutes. Observe no bleeding and stop the compression.
Don't rush to stand up, you can first move the lower limbs slightly to promote blood reflux, which can reduce dizziness and other reactions.
Drink more water within 4 hours after blood donation, and avoid strenuous exercise and excessive weight with blood collection arm or excessive force within 12 hours, so as not to affect the healing of the needle. When you find bruises on the needles, don't worry, it usually dissipates in about a week, and you can apply heat after donating blood for 24 hours.
400ml blood donation,
Will it be too much?
Most of the human body is water. In men, water accounts for about 60% of body weight, while women have more fat, and water accounts for about 55% of body weight.
Calculate: an adult man weighing 70 kg has a total blood volume of about 8% of his weight, so how much blood does he have?
The correct answer: about 5000ml. It turns out that 400ml is less than 1/10 of the total blood volume!
Usually, 1/5 of the blood in the human body is stored in the liver, spleen and other organs. Every time after donating blood, the tissue fluid in the human body and the blood stored in the spleen can make up the circulating blood volume after 1 hour. Therefore, donating 400ml of blood will not cause harm to our body.
Of course, our country has strict regulations on blood donation intervals. Professionals in blood centers will also give you professional guidance when donating blood to fully guarantee the safety of blood donors.
Is it safe to donate blood to the components?
According to different blood collection methods, blood donation can be divided into donation of whole blood and component blood, the latter is component blood donation. With the development of science and technology, almost all blood components can be collected by blood cell separators, such as red blood cells, platelets, plasma, granulocytes, etc.
The advantage of blood donation is that a single blood component with higher concentration and purity can be obtained by apheresis, and it can be infused to patients with related indications. This not only improves the efficacy, but also reduces the immune risk of the patient's exposure to multiple blood donors due to the low whole blood concentration.
I do not understand? for example.
At present, the main component of blood donation in my country is platelet collection. Taking this as an example, an apheresis platelet donated by a blood donor contains more than 2.5×1011 platelets, and the amount of these platelets is equivalent to the total amount of platelets in whole blood donated by about 7 blood donors. The transfusion of platelet apheresis from a blood donor can achieve the therapeutic effect of platelet concentration in 7 blood donors, which reduces the risk of immune reactions and transfusion infections.
For blood donors, platelets are collected, and other blood components are returned to themselves, which is more conducive to rapid recovery.
As for the risk of contracting diseases, such worries are unnecessary. The collection of apheresis platelets is performed using a blood cell separator under sterile and closed conditions, and all use strictly sterilized disposable consumables, which will not cause cross infection.
What if the donated blood fails?
When the blood of the blood donor leaves the body and enters the blood bag, it is sent to the blood center for sampling and testing by the laboratory. If the indicators of the test result meet national standards, the qualified blood is stored in the refrigerator of the blood bank and is ready to save the patient at any time. For blood that fails to be tested, the blood center will sterilize and discard it in strict accordance with relevant national regulations.
Why is blood donation free and blood paid?
The consensus between the World Health Organization and countries around the world is that voluntary blood donation is the safest source of blood. Since the act of unpaid blood donation has an altruistic spirit, the answer to the blood donor's health inquiry should be an honest answer from the unpaid blood donor to his own health and life history.
The paid use of blood actually pays for the costs of blood collection, testing, preparation, storage and transportation. The “Blood Donation Law of the People’s Republic of China” clearly stipulates that citizens must only pay for blood collection, storage, separation, and testing when they use blood for clinical purposes; the specific charging standards are set by the national health administrative department and price authority.
What is the use of free blood donation certificate?
The unpaid blood donation certificate is not only the honorary certificate of the unpaid blood donor, but also one of the vouchers for reimbursing the blood expenses after using the blood.
According to the "People's Republic of China Blood Donation Law", the use of blood donation certificates in reimbursement is divided into two situations:
First, for unpaid blood donors, the total amount of reimbursed blood within 5 years from the date of blood donation is calculated as 5 times the amount of blood donated, and after 5 years is calculated as the same amount. When the unpaid blood donation accumulates to 1000ml, blood donors will enjoy unlimited treatment with blood for life;
Second, when the spouse and immediate family members of an unpaid blood donor use blood, their accumulative reimbursed blood expenses will be charged based on the amount of blood donated by the donor.
Not only that, the use of unpaid blood donation certificates is increasing. Some provinces and municipalities have launched incentives to allow unpaid blood donors to enjoy free public transportation, free park visits, free medical examinations, free medical treatment fees, apply for unpaid blood donors for serious illness relief, and points to enter the house.
Blood donation certificates are becoming more and more useful, but is it very troublesome to carry it every day? Not afraid! The National Health Commission just issued a notice on June 11 to enable the nationwide unified electronic unpaid blood donation certificate. The National Electronic Blood Donation Certificate was officially launched on June 14 this year, "World Blood Donor Day", and the landing query platforms include the official website of the National Health and Health Commission, the Chinese government website, the national government service platform, and Alipay, WeChat, and Baidu applets.
There is also good news, the procedures for reimbursement of blood expenses are also getting simpler. Now the expense reimbursement is being moved to various blood-use hospitals, the purpose is to give unpaid blood donors and their relatives a one-stop fee reduction in blood use, and increase the sense of medical treatment of unpaid blood donors.

About World Blood Donor Day
Since 2004, the World Health Organization, the International Federation of Red Cross and Red Crescent Societies, the International Federation of Blood Donor Organizations, and the International Blood Transfusion Association have designated June 14 each year as World Blood Donor Day. The theme of this year's World Blood Donor Day is "Safe Blood Saves Life", with the slogan "Donate Blood, Make the World Healthier".
In 1998, in order to guarantee the safety of blood and protect the rights and interests of blood donors, the People’s Republic of China issued the Blood Donation Law of the People’s Republic of China, which marked the establishment of a free blood donation system in my country. After years of propaganda and promotion, the broad masses of people have a basic understanding of unpaid blood donation.
