Multifunctional ECMO circulating pipeline and method for performing extracorporeal membrane oxygenation by utilizing multifunctional ECMO circulating pipeline

Abstract

The invention discloses a multifunctional ECMO circulating pipeline and a method for performing extracorporeal membrane oxygenation by utilizing the multifunctional ECMO circulating pipeline. The ECMO circulating pipeline comprises an arterial circulating pipeline, a venous circulating pipeline, a blood purification inlet catheter and a blood purification transfusing catheter, wherein blood oxygen sensors are arranged on the arterial circulating pipeline and the venous circulating pipeline, and the blood oxygen sensors are connected with a blood gas detecting device; one-way valves are separately arranged at the ends, near the circulating pipeline, of the blood purification inlet catheter and the blood purification transfusing catheter. According to the ECMO circulating pipeline disclosed by the invention, the oxygen partial pressure of blood can be monitored in real time before and after blood oxygenation, the difficult problem that during an ECMO treatment period, blood collecting on two end pipelines is difficult, and the spraying probability of blood or a flushing fluid is high, can be solved, the oxygen partial pressure of the blood is detected in an nondestructive manner, and patients do not need puncture of major vascular pipelines twice; the blood oxygenation and the hemodialysis can be simultaneously realized by utilizing the ECMO pipeline, so that the pain of people can be reduced, and probable massive haemorrhage and infection can be effectively reduced.

Description

technical field

[0001] The invention belongs to the field of medical devices, and in particular relates to a multifunctional ECMO circulation pipeline and a method for performing extracorporeal membrane oxygenation using the same. Background technique

[0002] Extracorporeal membrane oxygenation (ECMO) circulatory system is mainly composed of membrane lung, centrifugal pump head and pipeline. The pipeline connects the membrane lung and the centrifugal pump head together, and connects with the blood vessels in the body through the arteriovenous cannula, drains the patient's venous blood to the outside of the body through the centrifugal pump, and makes the venous blood flow through the gas exchange of the artificial lung (oxygenator). Oxygenated into arterial blood, and then reinfused into the body to provide a stable circulating blood volume for patients with cardiopulmonary failure.

[0003] Clinically, the function of the oxygenator is judged by visually observing the col...
