ECMO (extracorporeal membrane oxygenation) closed pre-flushing equipment

Abstract

The invention relates to the field of medical instruments, and discloses ECMO (extracorporeal membrane oxygenation) closed pre-flushing equipment. The equipment comprises an ECMO device and a preciseinfusion kit communicating with the ECMO device, wherein the ECMO device comprises an ECMO machine, a centrifugal pump, a membrane oxygenator, a drainage tube from the membrane oxygenator outlet end to the centrifugal pump inlet end, a drainage tube from the centrifugal pump outlet end to the membrane oxygenator inlet end, and two interfaces on the drainage tube from the membrane oxygenator outletend to the centrifugal pump inlet end, the precise infusion kit comprises a backflow bag and a pre-flushing bag, the pre-flushing bag communicates with the backflow bag through a channel, the channelis provided with a filter head and a one-way check valve, and ECMO pre-flushing tubes connected with the two interfaces are respectively arranged at the lower parts of the pre-flushing bag and the backflow bag. According to the invention, pre-flushing liquid bubbles in the tubes are destroyed through the filter head, and the pre-flushing liquid passes through the one-way check valve and then performs circulating pre-flushing so as to realize the pipeline pre-flushing of the ECMO device. The equipment replaces air and bubbles in the pipeline, saves time, reduces the pollution, achieves thorough pre-flushing, ensures the effective implementation of ECMO, and fights for the time for rescuing patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ECMO closed prefilling device. Background technique [0002] Extracorporeal membrane oxygenation (ECMO) is a technique for rescuing patients with severe cardiopulmonary failure. It represents the level of critical illness treatment in a country, region, and hospital. At present, it is even believed that ECMO technology redefines the boundary between life and death. ECMO is an extracorporeal circulation technology out of the cardiac operating room. Its principle is to draw the venous blood out of the body, and inject it into the patient's arterial or venous system after being oxygenated by artificial cardiopulmonary bypass with special materials, so as to replace part of the heart and lungs and maintain human organs Oxygenated blood supply to tissues. [0003] The basic structure of ECMO includes intravascular cannula, connecting tube, centrifugal pump (artificial heart), oxygen...

AI Technical Summary

Problems solved by technology

[0006] With the advancement of technology, ECMO is used more and more in critical diseases, but the pipeline must be prefilled before use. If the prefill and exhaust are not complete, gas embolism may occur, causing membrane lung coagulation, threatening patient life

At the same time, incomplete priming once, time-consuming re-priming, and increased patient costs affect the timely and effective application of ECMO.
