Autologous blood recovery and concentration temperature variable filtration system

Abstract

The invention discloses an autologous blood recovery and concentration temperature variable filtration system. The filtration system comprises a blood recycling machine and a disposable supporting component. The blood recycling machine is formed by an artificial heart-lung machine and a heat exchange water tank, wherein the artificial heart-lung machine is provided with at least two rolling pump heads. The disposable supporting component comprises a suction tube, a suction channel, an anticoagulant drug bag, a blood storage device, an artificial kidney, a thermode, a blood filter and a transfusion cannula. The filtration system can be used for recovering lost blood in a surgery field in a surgical operation and recovering exudation at incisions after the operation and can also be used for recovering the lost blood of a non-infectious traumatic bleeder. Reclaimed blood is subjected to concentration, temperature change and filtration and is transfused back into a patient, blood components are not lost, and blood platelets in the blood and components containing blood coagulation factors in blood plasma are preserved; input of blood products containing various allogeneic components is reduced, input of allogeneic blood is decreased, and the occurrence rate of haematogenous infectious diseases is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment for blood recovery and filtration. Specifically, the invention relates to a filter system for recovery and concentration of blood. Background technique [0002] At present, blood shortages are occurring in hospitals all over my country. The reasons are, on the one hand, the increase in clinical blood consumption due to the increase in medical needs; It is difficult for this contradiction between supply and demand to improve in the short term. The long-term existence of this contradiction between supply and demand will inevitably lead to the failure of many hospitals to arrange elective operations normally, so that patients cannot receive timely treatment due to lack of blood sources. Therefore, the task of saving blood and even recovering lost blood for reuse is imminent. However, the blood recovery equipment currently in use can only recover red blood cells, while platelets, plasma, inc...

Problems solved by technology

[0005] In order to solve the problem of blood shortage in the prior art and the lack of blood components after washing in the existing blood recovery system and the problem of blood hypothermia, the inventor has completed a variable temperature filtration system for blood recovery and concentration after long-term research. The system can filter the recovered blood while controlling the variable temperature, so that the filtered blood will not lose blood components and keep the body heat
