Embodiment Construction

[0015] see figure 1 , the present invention includes a suction head 1, a blood storage and filtration tank 3, a blood storage pressurized bag 5, a blood ultrafiltration purifier 8 and a blood bag 12 which are sequentially connected by pipelines. The blood storage and filtration tank 3 includes an inner tank and an outer tank, the inner tank is arranged inside the outer tank, the side wall of the inner tank is a 40um filter screen, the suction head 1 is connected to the inner tank through a pipeline, and the outer tank is connected to the blood storage tank through a pipeline Pressurized bag 5, inner tank can filter hemagglutination fast tissue debris etc. Recover a certain amount of blood (500-1000ml) and open its second three-way valve 4 to allow the pre-filtered blood to enter the blood storage inner bag 15 of the blood storage pressurized bag 5, and the blood storage filter tank 3 is provided with a negative pressure suction tube 13 for smooth blood circulation.

Abstract

The invention discloses a blood transfusion system for autologous blood recovery, filtration and purification, which comprises a suction head, a blood storage and filtration tank, a blood storage pressurizing bag, a blood ultrafiltration purifier and a blood bag which are sequentially connected through a pipeline. The blood transfusion system has the advantages that by the aid of the complete system which is simple in structure, convenient in use and low in cost, outflow blood is effectively recovered, filtered and purified, impurity particles such as harmful free hemoglobin, inflammatory mediators, cell activation products, small tissue dross, micro-polymers and the like in blood are removed, the blood is concentrated, and adverse transfusion reaction caused by prior filtration-type blood recovery is eliminated. Besides, the system is capable of effectively retaining plasma components and blood platelet components in the blood, and avoiding the influence of cleaning out blood coagulation factors and blood platelets in the blood on a blood coagulation function during cleaning blood recovery. In addition, by the aid of the system, infectious diseases caused by homologous blood transfusion are avoided, shortage of blood sources is relieved, and the economic burden of a patient is reduced.

Description

technical field [0001] The invention relates to an autologous blood recovery, filtration, and purification blood transfusion system, in particular to an autologous blood recovery, filtration, and purification blood transfusion system that can effectively filter out harmful inflammatory factors in blood and retain red blood cells, platelets and plasma components in the blood. Background technique [0002] Blood salvage can be divided into cleaning blood salvage and filter blood salvage according to the processing method of collected blood. The filter type blood recovery is simple in structure and easy to operate. However, due to a certain degree of hemolysis, coagulation-fibrinolysis system and activation of inflammatory cells in the recovery process, and the recovered blood contains different concentrations of free hemoglobin inflammatory mediators and cell activation products, and may also be mixed with tiny particles such as fat particles. Impurity particles such as tissu...
