Abstract

The invention discloses a membrane oxygenator integrated with a centrifugal pump, the membrane oxygenator comprising a centrifugal pump system and a gas exchange device. The centrifugal pump system isfixedly arranged below the gas exchange device. The membrane oxygenator also comprises a blood inlet, a bleeding nozzle, an inlet nozzle and an exhaust nozzle. The membrane oxygenator integrated witha centrifugal pump provided by the invention is small in volume, convenient to carry and transport, and suitable for first aid, hospital operation and hospital transfer. The membrane oxygenator is convenient to connect and easy to use, is faster to operate, saves time, and allows users to start extracorporeal life therapy more quickly.

Description

technical field [0001] The invention relates to the technical field of medical device products, in particular to the design of a membrane oxygenator integrated with a centrifugal pump. Background technique [0002] The hollow fiber membrane oxygenator (hereinafter referred to as the oxygenator) is the gold standard of blood Yanghe today. During the long-term use, the oxygenator has been used as a device to support heart surgery from the beginning, and has gradually been applied to more and more Medical fields, such as respiratory support, first aid, newborns and even first aid in the field; [0003] Because the traditional oxygenator is a product developed for cardiac surgery, it only considers the short-term application in the operating room. Therefore, there are still many problems in the extended use of oxygenators currently on the market, especially when first aid, hospital transfer, and intra-hospital transfer need to carry out life support on the move, there are still...
