Problems solved by technology

[0003] At present, the existing blood processing system can only separate a single item, and cannot simultaneously store red blood cells and platelets and reinfuse replacement fluid; moreover, the system sets parameters for healthy people and collects them according to unit counts. More and no less, not suitable for patients' needs for autologous blood storage

Embodiment Construction

[0050] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0051] Such as figure 1 As shown, a blood processing system for autologous blood storage, the blood processing system includes a blood collection needle 1, a whole blood vessel 2, a centrifuge 3, an anticoagulant connection bag 4, a plasma collection bag 5, a platelet collection bag 6, red blood cell Collection bag 7 and replacement fluid connection bag 8;

[0052] One end 21 of the whole blood vessel channel 2 communicates with the blood collection needle 1, and the other end 22 of the whole blood vessel channel 2 communicates with the blood inlet pipe 31 on one side of the centrifuge 3; The blood vessel channel 2 is connected, and the nozzle 312 at the other end is extended to the bottom of the body of the centrifuge 3;

[0053] The whole blood vessel channel 2 is provided with a pump A23, the average whole blood flow rate of the pump...

Abstract

The invention discloses a blood processing system of autologous blood collection and a method for processing blood by employing the same. The method includes that one end of a whole blood channel is communicated with a blood-taking needle, the other end of the whole blood channel is communicated with a centrifugal machine, a blood-separating outlet pipe is arranged on the other side of the centrifugal machine, and the blood-separating outlet pipe is provided with a turbidity detector. A platelet-collecting bag is communicated with the turbidity detector through a platelet-collecting tube, a plasma-collecting bag is communicated with the platelet-collecting tube through a plasma-collecting tube, and the platelet-collecting bag is communicated with the whole blood channel between a pump A and an anticoagulant tube through the plasma-collecting bag. The method is convenient in operation, safe and reliable. Red blood cells and platelets can be collected simultaneously, and therefore complicated separation of blood cells for a single purpose is decreased. By performing autologous blood collection and supplementing displacement liquid for a patient during the course of collection, the balance of intake and output quantity by the patient is guaranteed. Compared with the prior art, the blood processing system of autologous blood collection is more secure, and cost of medical blood transfusion is greatly reduced.

Description

technical field [0001] The invention relates to a blood treatment system and a treatment method thereof, in particular to a blood treatment system for autologous blood storage and a blood treatment method using the system. Background technique [0002] According to different working mechanisms, there are basically three ways to separate different components in human whole blood. 1) Centrifugal type: mainly according to the different proportions of various components in whole blood, after different centrifugal forces, red blood cells, granulocytes, lymphocytes and platelets in plasma components and blood cell components can be stratified and separated, and the required components can be extracted or removed. For pathological components, other components are returned to the person who provided the whole blood. 2) Membrane filter type: It mainly relies on the sieve function of the polymer membrane material to sieve substances with different particle sizes. The larger particles...
