1998 10 since the promulgation and implementation of the blood donation law on June 1 0, the number of blood donors in our city has exceeded 30,000, and 100% of clinical blood comes from unpaid blood donation. Most people have a high understanding of blood donation, but what is the difference between donating platelets and donating blood in general? What is machine-collected platelet? Is mechanical collection of platelets harmful to the body? Why do I still have to pay for collecting platelets? ..... most people are not very clear.
Usually, blood donation generally refers to donating whole blood, and donating platelets is a component of blood donation, that is, blood donation component. Human blood consists of red blood cells, white blood cells, platelets, plasma proteins and other components. Blood donation component refers to the voluntary blood donation of healthy citizens who donate a component of their blood through a blood separator. Donate the machine to collect blood components and enjoy 800 ml of whole blood. The donated components can be platelets, granulocytes or peripheral hematopoietic stem cells. At present, donation of mechanically collected platelets is the most common in China.
Donating platelets is beneficial and harmless.
Platelets are mainly involved in coagulation and hemostasis in the body. The number of platelets in normal blood is 654.38+10,000 ~ 300,000/m3. Clinically, blood diseases, such as leukemia, aplastic anemia, intraoperative hemorrhage, etc., all need to use platelets in time to save patients' lives.
So, what's the difference between donating blood and donating platelets collected by machines? Blood donation is a process of collecting all blood components. Collecting platelets by blood donation machine is a process of collecting platelet components in blood by blood cell separator and returning other blood components to blood donors.
The survival period of normal human platelets in vivo is 8- 1 1 day, and the number of platelets remains within the normal range after blood donation. Therefore, as long as it meets the requirements of blood donation by machine-collected components, it will not have any impact on the body after collection, and it can also carry out normal work and study. Blood donation components are also conducive to reducing blood viscosity and cholesterol of blood donors, which is more conducive to protecting human health.
In the process of donating platelets collected by machine, the blood of platelets collected by machine is strictly disinfected and then circulated and separated in a disposable brand-new closed tube sleeve, which will never cause cross-contamination and infection, and is very safe.
Since blood donation ingredients are good for health, why has blood donation been implemented for several years, but the paid service of collecting platelets by machine has just started? This is because it takes a long time (about 45 minutes) to collect platelets by machine, plus the time required for donors to go back and forth, which usually takes 2 to 3 hours, which delays the work and study of donors. Therefore, it has always been to give donors a certain subsidy.

Donating platelets is the same as donating blood, which is equivalent to storing blood in blood, just like buying a safety insurance. According to the relevant regulations, the donation of therapeutic platelets is calculated by donating 800 ml of whole blood. According to the regulations of our province, unpaid blood donors can enjoy unlimited free blood use for life, and once blood donors collect platelets by machine, they can enjoy free blood use for life. In addition, their immediate family members can use the same amount of blood for free. Blood donors have donated 8,000 ml, 6,000 ml and 4,000 ml successively, and they can get the gold, silver and bronze prizes for unpaid blood donation issued by the state.
Under normal circumstances, after donating platelets, it takes only 3 days for human platelets to return to the level before donation. According to national regulations, the interval between donating platelets collected by machine is generally 28 days. If it is more than 14 days and less than 28 days, the platelet count must reach150,000/cubic millimeter. In addition, keep the needle eye clean after blood donation to prevent infection at the puncture point. You can work and live normally, but don't take part in strenuous exercise. If there is blue around the eye of the needle, it is because there is a small amount of blood flowing out of the blood vessel. Take it easy. Do a hot compress and it will fade in a few days.
Keep in mind the conditions and pay with enthusiasm.
Donating platelets is the same as donating blood. You should bring valid certificates, fill in the Registration Form of Free Blood Donation at the Red Cross Blood Station, and donate platelets after passing the physical examination, blood sample collection, platelet count and rapid detection.
According to the blood donor's platelet count, the general collection time takes 40 minutes to 60 minutes. Donors must meet the following conditions: age 18-55 years old; Weighing more than 50 kilograms; The physical examination results are qualified; The peripheral platelet count meets the collection standard (greater than or equal to10.5 million/cubic millimeter); The blood vessels on the arm are obvious; Blood components need special equipment and venues. At present, blood donors can only donate platelets at blood stations. If you want to donate blood platelets in the street, you can also donate blood from the blood station to the station, or you can donate blood to the blood station yourself. The blood station will give 50 yuan RMB as a transportation subsidy. Please note the following before donating:
1. Blood donors should avoid high-fat foods such as chicken, meat, fish, milk, eggs and bean products the day before blood donation and in the morning.
2, the day before blood donation should ensure adequate sleep, do not drink, drink more water, eat breakfast that day, do not donate blood on an empty stomach.
3. Blood donors should not take drugs that inhibit platelet aggregation or platelet metabolism one week before blood donation, such as aspirin, vitamin E, indomethacin, dipyridamole, aminophylline, chloramphenicol and antiallergic drugs.
4. Ensure adequate sleep and stable mood before blood donation, avoid mental stress and relax.
In short, platelets will be donated free of charge nationwide from 10/day. In order to ensure the use of platelets in clinical rescue, on the one hand, all medical units are required to strictly control the use of platelets and mobilize relatives of patients to donate platelets to blood stations. On the other hand, the media should give full support, increase publicity, encourage all healthy citizens of school age to actively participate in blood donation, and contribute to the creation of a healthy city and the construction of a harmonious port city.
