Background

ECMO is a medical emergency treatment device, which is an external Membrane Oxygenation (Extracorporeal Membrane Oxygenation) for Extracorporeal respiration and circulation of a patient during cardiopulmonary surgery, such as severe cardiopulmonary failure and heart transplantation. Besides the heart and lung function of the patient can be temporarily replaced, the load of the heart and lung of the patient is relieved, and more treatment time can be won for medical personnel.

The ECMO is characterized in that venous blood in vivo is led out of a human body, is oxygenated by an artificial cardiopulmonary bypass made of special materials and then is injected into an artery or vein system of a patient, so that a partial cardiopulmonary replacement effect is achieved, and the oxygenation blood supply of human organ tissues is maintained. In ECMO operation, blood is drawn from the vein and passes through the membrane lungs to absorb oxygen and remove carbon dioxide. When the lung function of a patient is seriously damaged and the conventional treatment is ineffective, ECMO can undertake the gas exchange task, so that the lung is in a rest state, and precious time is won for the rehabilitation of the patient. Also, when the cardiac function of the patient is seriously damaged, the blood pump can replace the cardiac pumping function to maintain the blood circulation.

With the development of scientific technology and the increase of cardiac intervention, the use frequency of ECMO is increasing, however, in clinical use, the use of ECMO is accompanied by huge risks, such as bleeding, thrombus formation, infection formation and the like; in the process of ECMO treatment, the difficulty of ECMO arterial catheterization or venous catheterization is high, the operation is not easy, the problems of failed catheter cleaning, blood vessel tearing or pipeline obstruction and the like can be caused once the operation is failed, great pain can be brought to a patient, and doctors lack related ECMO pipeline puncture training in ordinary training, so that a human body model trainer which can enable doctors to simulate and train ECMO arterial catheterization and venous catheterization is urgently needed.
