In winter, the temperature dropped sharply, and the number of blood donors on the street decreased.
Changsha needs at least 500 healthy citizens to participate in blood donation for free, in order to ensure the need for clinical treatment of clinical treatment of more than 200 hospitals in the city.
Changsha Blood Center drove the blood donation vehicle into colleges, troops, units, and communities to facilitate caring citizens to donate blood nearby, and strengthened group blood donation to preach.
Hunan Medical Chat on the 4 categories of the citizens’ most concerned, and invited Wang Shuanglin, director of Changsha Blood Center, and Xie Yubin, director and chief technician of the Changsha Hematology Center, and chief technician.

College students are the main force of Changsha for free blood donation, and about 10%of college students have participated in free blood donation.
The lecturers learned that, in addition to physical reasons and wait -and -see psychology, about 30%of the respondents have always expressed their doubts about the safety of blood donation.
"AIDS and hepatitis B are all diseases that can be transmitted through blood. Is there any possibility of being infected with blood donation?"
Many people’s doubts come from a half -knowledge of health knowledge.
Wang Shuanglin, director of the Changsha Blood Center, said that we must first understand the spread of viruses such as AIDS, hepatitis B, and syphilis.
The first is to spread through sexual contact.
The second is the spread of maternal and infants, that is, mothers who have been infected with AIDS, hepatitis B or syphilis virus can infect the virus to fetuses or infants during pregnancy, childbirth and breastfeeding.
The third is blood transmission.
If the blood or blood products of the infected person are used, the organs or tissue of the infected person is transplanted, and the damage of the skin and mucous membranes is exposed to the blood of the infected person;
Use toothbrushes and shaver with infected people, and not completely disinfected in syringes;
When using tattoos, tooth extraction, and foot repair, the virus is used to be contaminated by the virus, which may be infected with viruses such as AIDS, hepatitis B, and syphilis.
"It is certain that the blood donor will not be infected with the disease at any blood donation point in Changsha." Wang Shuanglin said.
The blood donation vehicle and blood donation house in Changsha are all in Changsha’s blood center. The Changsha Blood Center is a public welfare institution that does not take for profit.
All blood collection and testing consumables at all blood donation points are all disposable sealing sterile consumables purchased in accordance with national health standards.
The "one person, one shot and one blood bag" is used to ensure that the blood donor will not be infected with the disease.
Since October 1, 1998, my country has implemented the "Blood Donation Law of the People’s Republic of China", and there have been no cases of infection with blood donation infection in the country.
Wang Shuanglin emphasized that the Changsha Blood Center follows the national regulations to detect the blood donor’s blood transmission of blood transmission disease, and the detection of qualified blood will be used for clinical practice. Unqualified blood is reported to waste treatment in accordance with national regulations.
Unqualified blood test results only indicate that the blood does not meet the requirements of national blood standards, and does not use it as a diagnosis basis for infection or disease.

my country’s "Blood Donation Law" stipulates that citizens participate in unpaid blood donation, and each time the amount of blood donation is 200 to 400 ml.
Some blood donors will be entangled how much blood is donated.
For eligible blood donors, blood collection nurse advocates 400 ml of blood donation.why is that?
"200 ~ 400 ml of blood donation will generally not affect the health of blood donors." Said Xie Yubin, director and chief technician of the Changsha Hematology Center, said.
An adult weighing 60 kg, the blood volume of the whole body is about 4000 ~ 5000 ml.
80%of blood circulates in the blood vessels to maintain normal metabolism of the human body; 20%temporarily stay in the liver and spleen to prepare from time to time.
When a normal person donates 200 ~ 400 ml of blood at a time, the blood on the liver and spleen will be released to the peripheral blood circulation system, and the normal physiological level can be restored quickly.
Human blood has many blood cell aging and death every time, and at the same time, there are a large number of new cells.
Xie Yubin said that those who have long adhered to the appropriate amount of blood donation for a long time have been continuously stimulated because of the bone marrow hematopoietic system and enhanced the hematopoietic function. It has a strong metabolism and constantly produces young blood cells with more vitality.
Therefore, a healthy person to participate in blood donation according to the prescribed interval will not have any impact on the body, but it is good for health.
Xie Yubin said that the qualified blood donor, 400 ml of blood donation at a time, has the following benefits to the recipient:
The first is due to the window period of blood testing.
In the early stages of blood infection of the blood, the current technology cannot be detected. This time is called the window period, but the blood in the window period is already infectious.
For example, using the most advanced nucleic acid testing technology, the detection of HIV virus is still a 10 -day window period. If the blood donor is just infected with the HIV virus, the anti -HIV antibody is not detected in the blood within 10 days, the blood may be suffered.Blood infection.
Therefore, blood transfusion is still risky.
Usually one blood transfusion treatment requires 400 ~ 600 ml of blood. If a blood donation is 200 ml of blood, at least 2 to 3 people donate blood, and the chance of blood transfusion infection will be more than doubled.
The second is that blood transfusion immune reactions have been significantly reduced.
During the blood transfusion process, the body may produce many immune reactions, such as causeing fever and allergic reactions.
Infusion Single -person blood products are compared with multiplayer blood products that can reduce the blood input of the blood input, and the probability of adverse blood transfusion reactions will be greatly reduced, which will further ensure blood transfusion safety.

In the survey of the Changsha Blood Center, some citizens have such questions: now blood donation is free, but why does it cost when going to the hospital with blood?
Is there a profit from the relevant departments from public welfare?
Wang Shuanglin said that blood donors were donated for free to ensure the safety of clinical blood.
Volunteer blood donation is the safest source of blood. This is the consensus of the world’s health organizations and countries around the world.
Although blood testing technology is constantly improving, it is limited to the level of science and technology and economic development. At present, it cannot completely exclude the risk of all known blood transmission diseases, and it is impossible to rule out the risk of unknown new infectious diseases.
Therefore, the health consultation of blood donors, especially the reflection of the authenticity of their own health and life history, is the effective basis for ensuring the blood of their health and life history.
Patients are paid for blood, and they pay the costs of blood collection, testing, preparation, storage and transportation.
The "Blood Donation Law of the People’s Republic of China" clearly stipulates that when citizens are used in clinical blood, they only need to deliver the costs of blood collection, storage, separation, and inspection. The specific charging standards are formulated by the national health administrative department and the competent price department.
Although blood was donated for free blood donors, the blood needed to go through a series of treatment processes before the blood was used for clinical patients, including blood collection, testing, separation, storage and transportation, etc.And management and other costs.
Blood testing only involves ABO blood type, RH blood type, hemoglobin (HB), canopyr aminotransferase (ALT), hepatitis B virus (HBV), hepatitis C virus (HCV), human immune defect/HIV/AIDS (HIV/AIDS), Syphilis Spiral (TP) and other items to detect multiple items.
In order to ensure blood safety, the blood station is constantly strengthening management, improving technology, and improving services.

If you or his family need to use blood, if he or his family needs to use blood, it is convenient to reimburse with blood costs. It is a question of many free blood donors.
Is the problem that has been criticized in the past that "blood donation is easy to reimbursement" has been solved?Wang Shuanglin made a reply.
Wang Shuanglin introduced that starting from June this year, Changsha has fully implemented direct reporting of blood donation for free blood donation, and the cost of blood donors for free of charge does not need to run eastward.
The blood donor himself (including those in Changsha, other prefectures in the province and other provinces and other provinces participating in free blood donation) and their direct relatives can be reimbursed directly in the hospital.
According to relevant regulations, if the amount of blood donation is more than 900 ml, the blood donor himself reimburses the clinical blood costs for life;
If the amount of blood donation is less than 600 ml of less than 900 ml, the blood donor himself reimburses the cost of blood donation three times the cost of clinical blood;
If the amount of blood donation is below 600 ml, the blood donor himself reimburses the cost of blood donation of blood for clinical blood;
In addition to the blood donor himself reimbursed the cost of blood in accordance with the regulations, the spouse, parents, and children of the blood donor can also pay a total of the cost of clinical blood for blood donation.
