Uninterrupted plasma supply device for plasma exchange in extracorporeal circulation blood purification

Abstract

The invention provides an uninterrupted plasma supply device for plasma exchange in extracorporeal circulation blood purification, and belongs to the technical field of medical instruments. The uninterrupted plasma supply device comprises a supporting plate, a blood transfusion bag, a liquid collecting box, blood transfusion tubes and blood control mechanisms, wherein the supporting plate is vertically arranged on a blood transfusion frame; the blood transfusion bag, the blood transfusion tubes and the liquid collecting box are sequentially connected in series; the blood control mechanisms areused for controlling blood plasma flow and on-off in the blood transfusion tubes; and the multiple blood control mechanisms are matched to enable blood plasma in the blood transfusion tubes to be sequentially conveyed to the liquid collecting box. By the uninterrupted plasma supply device for plasma exchange in extracorporeal circulation blood purification, continuous plasma exchange can be carried out for a patient; in the process, frequent pause of blood flow in the blood purification loop due to blood plasma exchange is avoided, blood coagulation is prevented, the risk of interruption or failure of blood purification is greatly reduced, the workload of medical staff is reduced, the operation is simple, the overall time of blood purification is shortened, the risk of extracorporeal circulation of a patient is reduced, and the pain of the patient is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to an uninterrupted plasma supply device for plasma replacement in extracorporeal circulation blood purification. Background technique [0002] Blood purification treatment refers to taking the patient's blood out of the body, and using a purification device to remove some pathogenic substances in it, purify the blood, and achieve the purpose of treating diseases. Blood purification includes: hemodialysis, hemofiltration, hemoperfusion, plasma exchange, immunoadsorption, etc. Plasma exchange is to introduce the patient's blood into a plasma exchange device, discard the separated plasma containing metabolic toxins, and supplement the same amount of fresh plasma or plasma substitutes to achieve the purpose of treating diseases. It is widely used in intensive care medicine, blood Department of Internal Medicine, Department of Gastroenterology, Department of Imm...
