Description

Oxygen repeater used between oxygen and extracorporeal membrane lung oxygenator

The technical field is as follows:

the invention relates to an oxygen repeater used between oxygen and an extracorporeal membrane lung oxygenator.

Background art:

ECMO is an English abbreviation of extracorporeal membrane oxygenation (extracorporeal membrane oxygenation) and is an extracorporeal circulation technique that can be performed at the bedside of a patient. The venous blood in the body of a patient is drained to the outside of the body, and is re-injected into the artery or vein of the patient after being oxygenated by an artificial cardiopulmonary bypass, so that the function of cardiopulmonary replacement is achieved, and the blood and oxygen supply of human tissues is maintained. ECMO is mainly used to provide continuous external respiration and circulation to patients with severe cardiopulmonary failure to sustain the life of the patients and to win valuable time for the rescue and treatment of critically ill patients.

ECMO works on the principle of drawing blood out of a vein, oxygenating the blood in vitro through a membrane lung, removing carbon dioxide, and infusing oxygenated blood back into the patient, thereby providing life support to the patient. When ECMO continuously operates, the membrane lung oxygenation must be externally connected with an oxygen source and sufficient oxygen supply is ensured, and if insufficient oxygen pressure or sudden oxygen interruption occurs, poor membrane lung oxygenation is caused, the blood oxygen saturation of a patient continuously decreases, the blood pressure decreases, arrhythmia occurs, and if the problem of oxygen supply cannot be solved in time, the life safety of the patient is seriously threatened.
