Technical Field

The invention belongs to the technical field of ECMO equipment, and particularly relates to an ECMO flow diverter.

Background

ECMO is the English abbreviation of Extracorporeal Membrane Oxygenation (Extracorporeal Membrane Oxygenation), an Extracorporeal circulation technique that walks out of the heart operating room. The principle is that the venous blood in the body is led out of the body, oxygenated by an oxygenator and injected into the artery or vein system of a patient, so that the function of partial cardiopulmonary replacement is achieved, and the perfusion and oxygen supply of tissues are maintained.

ECMO consumptive material is disposable high value consumptive material, and basic structure includes: an intravascular catheter, a connecting pipe, a power pump (artificial heart), an oxygenator (artificial lung), an oxygen supply tube and a monitoring system. The disposable part is usually formed into a kit clinically, and the non-disposable part is stored in a binding way and is designed to be movable, so that the emergency capacity is improved.

The ECMO technology is suitable for sudden and reversible severe cardiopulmonary insufficiency, and is particularly suitable for the emergency treatment of severe ARDS, influenza A, avian influenza, poisoning and drowning, sudden cardiac respiratory arrest, heart or lung transplantation and the like. With the improvement of the ECMO technology, the ECMO gradually appears in the mobile medical treatment and air rescue processes, so that the life safety of more emergency and critical patients outside the hospital is guaranteed.

Blood flow in the ECMO treatment process is a direct index of the auxiliary degree of the heart and lung functions, and higher blood flow can make hemodynamics of patients unstable and increase damage of blood components to generate hemolysis; lower blood flow does not serve the therapeutic purpose of improving circulation and oxygenation, while increasing the risk of intravascular coagulation. The conventional VV-ECMO or VA-ECMO equipment can detect and control the flow, but the VAV-ECMO or VVA-ECMO lacks a precise device for monitoring the flow of a shunt pipe, and the shunt control equipment used in the VAV-ECMO or VVA-ECMO is less at present, one is to manually control a pipe clamp to control the flow, and the use effect is poor; the other method is to use a Hoffman clamp for control, and the flow can be controlled but cannot be accurately controlled and monitored in real time. The problems of the series can bring certain troubles to clinicians, so that the doctors cannot accurately control the flow in the shunt pipes and visually know the change of the flow in the shunt pipes, the accurate diagnosis and treatment of the doctors to patients and the effect of ECMO auxiliary treatment are influenced, and hidden dangers are buried for the safety of the patients. Moreover, once the blood clots in the pipelines occur to generate thrombus, the ECMO bag needs to be replaced, which brings heavy economic burden to the family of patients.

Therefore, the application provides an ECMO flow shunt that can play accurate control flow and can monitor the flow in real time.
