The present invention uses steps as follows:

1. Blood collection

1.1 Select the puncture site and blood vessel: the elbow should be clearly visible, thick, plump, elastic, relatively fixed, and not easy to slide veins, such as median cubital vein, cephalic vein, basilic vein, etc.;

1.2 Disinfection of the puncture site: Dip a sterile cotton swab with an appropriate amount of disinfectant, center on the puncture point, and swab it spirally from inside to outside for 2-3 times, and the disinfection area is not less than 6cm×8cm;

1.3 Disinfection time limit: after disinfection, keep it for about 1 minute before puncturing. If it exceeds 3 minutes, it should be disinfected again;

1.4 Puncture: The side-opening blood vessel and the skin form an angle of 30°-45° and penetrate into the skin at an angle of about 10°. Puncture the blood vessel smoothly along the vein, advance about 0.5-1cm, fix the blood collection needle 1, and protect the needle eye of the blood collection needle 1. .

1.5 Take samples: clamp the blood collection tube clamp 5, open the sampling tube clamp 2, and after taking the required sample volume, close the sampling tube clamp 2, open the blood collection tube clamp 5, and collect the required blood volume;

1.6 Blood collection: Always communicate with blood donors to observe whether there are any adverse reactions of blood donation. If any adverse reactions occur, they should be dealt with in time. While collecting blood, shake it gently to mix the blood with the preservation solution until the required amount is collected. Blood volume, a blood donor uses a set of blood donation signs to identify blood collection bags 6, blood collection tubes 4 and blood samples;

1.7 Protection of blood donors: After the collection is completed, close the blood collection tube clamp 5, pull out the needle, and instruct the blood donor to press the punctured eye with the index finger and middle finger for more than ten minutes. After no bleeding, the wound can be replaced with a bandage, or the punctured area can be wrapped with an elastic bandage;

1.8 Heat-sealing blood: Push up the needle locking device of the blood collection needle 1, heat-merge and remove the blood collection needle 1, treat the blood collection needle 1 as medical waste, and heat-seal the blood pipeline;

2. Blood filtration

Hang the blood collection bag 6, open the bypass clamp 10, the blood flows to the entrance of the bypass tube 9, close the bypass clamp 10, open the front delivery tube clamp 11, the rear delivery tube clamp 12, and collect the blood into the blood storage bag 13 after filtration In the middle, until the filtration is completed, open the bypass clamp 10, after the blood is exhausted, close the delivery tube clamp 12 and heat the pipeline, and treat the blood collection bag 6 and the filter device as medical waste;

3. Blood transfusion

Hang the normal saline bag for injection (transfusion bag 16) and blood storage bag 13 upside down, open the infusion tube clip 17, open the blocking piece at the outlet of the infusion bag 16, pre-flush the blood transfusion set with normal saline, and close the infusion tube after establishing the venous access Clip 17, open the transfusion tube clamp 15, start blood transfusion, adjust the flow regulator 19, adjust the number of drops, observe the patrol blood transfusion process, until the blood transfusion is completed, close the transfusion tube clamp 15, open the transfusion tube clamp 17, rinse the transfusion with normal saline Blood vessels until flushed clean;

4. Whether to dial the needle according to the needs of the disease

Put the blood bags and pipelines generated during blood collection and blood transfusion into the outer packaging bag and seal them to complete a blood collection and transfusion process.

The blood collection and transfusion integrated device of the present invention realizes the seamless connection between the blood vessel of the blood donor and the blood vessel of the blood recipient, and avoids the possibility of blood contamination to the greatest extent; realizes the perfect combination of the blood collection bag, the white blood cell filtering device and the blood transfusion device There are three different functional requirements for blood collection and transfusion, which are suitable for the carrying, transportation and storage of medical teams or individual arms; according to the national occupational exposure protection requirements, sharp weapons should be treated in a harmless manner, and the needle lock protection after use is realized, which is effective Protect the environment and meet the protection needs in the process of medical waste disposal. In view of the poor environment, poor sanitation, and incomplete skin disinfection of the blood collection area in the field, and the possibility of potential blood contamination, secondary protective measures are adopted to avoid blood contamination: first, after skin disinfection, take off the needle cap to For protection during the completion of the puncture, a blood collection tube clip 5 is installed on the blood collection tube 4 close to the blood collection needle 1 to block the pollution caused by air entering the blood collection bag 6 during this period; 3. Collect the blood collected initially to cut off the possibility of potential blood contamination; in addition, according to the unconventional conditions in the field, there is no conventional blood collection equipment, and the blood collection cannot be measured.
