There should be many friends who have donated blood for free, but do you know how to prepare qualified blood? This may be a lot of friends do not know, here Xiaobian on their own blood donation experience to tell you.

Preparation before blood donation

1. Do not take medicine three days before blood donation. Of course, this is in the case of physical health. If you are not fit, you are advised not to participate in blood donation activities. Because once our body is in an unhealthy state, our blood also contains corresponding antagonistic substances, which is not a good thing for blood transfusion. And if we take medicine, there will be drug residues in the blood, which will affect the blood function. For example, aspirin can reduce some functions of platelets within three days.

2. On the day before blood donation and on the day of blood donation, do not drink alcohol (because alcohol and other substances will also enter the blood), and do not eat greasy food (high fat, high protein) to avoid blood transfusion reaction and pain caused by "fat blood". But also don't starve to donate blood, can enter some light diet, such as bread, steamed bread, porridge and so on.

3. We should keep enough sleep and have a good mood. This is very necessary, because once we have negative emotions, our body will also produce related hormones, sometimes directly leading to the blood is useless.

Precautions in blood donation

1. When donating blood, we usually register and fill in the physical examination form. Weight measurement, blood pressure measurement and physical examination by doctors.

When donating blood, you must first inform the doctor and make preparations early.

2. On the day of blood donation, you should have a proper rest. Do not exercise strongly within 2-3 days. You can work and live normally. Keep the outside of the needle eye of the blood drawing place clean to avoid infection or health impact. In addition, you can add some nutrition, eat some eggs, milk, lean meat, bean products, vegetables and other food, but don't overeat.

3. Do not touch the sterilized part after disinfection. Submit the registration form of physical examination and blood collection label for blood collection. Please clench your fist before the blood sampling and puncture. When the blood sampling needle enters the vein, clench and relax your fist until the blood sampling is completed. After blood collection, hold the hemostatic cotton ball for at least 5 minutes. Please do not twist the cotton ball to prevent subcutaneous hematoma and blood outflow. You can bend your elbow, clamp the cotton swab directly, and then take a rest.
