Problems solved by technology

[0006] In view of the above-mentioned technical problems of the prior art, the object of the present invention is to provide a method for establishing a storage-type autologous component blood transfusion system in the third trimester of pregnancy. By studying the change rule of the blood quality of the autologous whole blood in the third trimester of pregnancy during the blood storage process, it can be used to change the blood resistance. Two technologies of coagulation ratio and autologous blood component separation solve the problem of storage autologous blood storage and autologous blood retransfusion due to blood hypercoagulation in late pregnancy

Embodiment 1

[0055] 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. Immediately after blood collection, the blood was stored at 4°C, and the components were separated within 6 hours.

[0056] The preparation steps of blood components in the present embodiment 1 are as follows:

[0057] (1) Before centrifugation, check whether the 300ml sealed triple bag is damaged and wheth...

Abstract

The invention relates to an establishing method of a pregnancy late trimester storing type autologous component blood transfusion system. A 300 ml sealing three-connecting-bag system is used. The anticoagulant capacity in a sealing three-connecting bag is normal capacity, 300 ml autologous blood is collected, the autologous blood is made into blood components in six hours, and the fact that a whole process is kept in a cold chain state is guaranteed. The blood components are suspension erythrocytes and frozen fresh plasma. A scientific basis is provided for establishing of the pregnancy late trimester storing type autologous blood transfusion standard, accordingly, storing type autologous blood transfusion can be well used in obstetrics patients, safety, effectiveness and economy are achieved, and therefore promotion and application of storing type autologous blood transfusion in obstetrics are well achieved.

Description

technical field [0001] The invention relates to a method for establishing a storage type autologous component blood transfusion system in late pregnancy. Background technique [0002] Preoperative autologous blood donation (PABD): The patient's own blood is pre-collected several weeks or even months before the operation for preservation, and the preserved blood is reinfused when the patient needs blood transfusion. In some developed countries such as Europe and the United States, as the population gradually ages, the number of voluntary blood donors continues to decline, and blood sources are gradually decreasing. With the alarming increase in the demand for blood transfusion in cardiovascular and tumor operations, the shortage of blood sources has become a problem. This also prompts medical workers to consider other ways to meet clinical blood needs, such as the development of autologous blood transfusion, especially stored autologous blood transfusion, which is a better a...
