Embodiment 1
[0050] The method for establishing a storage type autologous component blood transfusion system in the third trimester of pregnancy of the present invention adopts a 300ml sealed triple bag system, increases the anticoagulant capacity in the blood bag and collects 200ml of autologous blood, mixes the blood after collection, and stores it in a blood storage refrigerator at 4±2.0°C Inside. A total of 25 cases.
[0051] In this example, the subjects of autologous blood collection are puerperas with indications for autologous blood transfusion, and the indications for autologous blood collection are after excluding cardiovascular system diseases, diabetes, hypertensive disorders during pregnancy, infectious diseases, and medical complications, there are no signs of labor or illness Stable parturients without vaginal bleeding, fetal growth restriction and intrauterine hypoxia; and the parturients meet the criteria: Hb>105g / L, Plt>100×109 / L. The timing of blood storage is 15-25 day...
Embodiment 2
[0053] The method for establishing the storage-type autologous component blood transfusion system in the third trimester of pregnancy of the present invention adopts a 300ml sealed triple bag system, the anticoagulant capacity in the sealed triple bag is a normal amount, and 300ml of autologous blood is collected, and the autologous blood is separated within 6 hours to prepare components The blood is guaranteed to be in a cold chain state throughout the whole process; the blood components are suspended red blood cells and frozen fresh plasma. 285 cases completed the whole clinical application research, of which 50 cases completed the whole process of blood quality testing.
[0054] The preparation steps of blood components in the present embodiment 2 are as follows:
[0055] (1) Before centrifugation, check whether the 300ml sealed triple bag is damaged and whether the labels are complete and consistent;
[0056] (2) Register the use of the centrifuge on the computer before t...
