The present invention discloses an integrated type external life support extracorporeal membrane oxygenation (ECMO) device. The integrated type external life support ECMO device comprises an oxygenator and a centrifugal pump, the oxygenator is provided with an upper cover, a lower cover and an oxygenation part arranged between the upper cover and the lower cover, the oxygenation part is provided with an accommodating space, the upper cover is provided with a blood inlet pipe communicating with the accommodating space, the centrifugal pump penetrates through the lower cover and the oxygenationpart and is in sealed connection with the lower cover, blood can directly flow into the centrifugal pump after entering from the blood inlet pipe, the centrifugal pump drives the blood flowing into the centrifugal pump to rotationally flow, the rotationally flowing blood flows into the accommodating space of the oxygenation part after flowing out of the centrifugal pump and is fully oxygenated inthe oxygenation part. The integrated type external life support ECMO device is compact in structure, small in size, easy to carry and use, small in required blood pre-filling amount, short in blood flow path and high in oxygenation efficiency during use, at the same time can also avoid a large pressure drop of the blood flowing through the integrated type external life support ECMO device and canmore effectively support life of patients.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated extracorporeal life support ECMO device. Background technique [0002] Extracorporeal membrane oxygenation (ECMO for short), is an important technology that uses ECMO equipment to provide life support for critically ill patients who have lost cardiopulmonary function. The current ECMO equipment generally includes structures such as intravascular intubation, a power pump (artificial heart), an oxygenator (artificial lung), and a pipeline connecting the pump and the oxygenator, among which the power pump (artificial heart) and the oxygenator ( Artificial lung) needs to be connected through pipelines, and its overall structure has the disadvantages of scattered structure and large volume, which is not easy to carry, and when in use, the priming liquid required to fill the connection pipeline between the pump and the oxygenator occupies more than 20% Precharge....
