Abstract：Cardiopulmonary machine is effective in rescuing patients with heart failure and respiratory failure, especially the
extracorporeal membrane oxygenation technology, which can provide effective circulatory support for patients with cardiopulmonary
failure, and win time for recovery of heart and lung function, and has good therapeutic effect for patients with severe COVID-19.
This paper made an in-depth analysis and research on the invention patent application of cardiopulmonary machine at domestic and
overseas from three aspects: the development trend analysis of cardiopulmonary machine technology, the innovation subject analysis
and the patent competition situation analysis. Through the analysis of this paper, we hope to help technicians in this field to carry out
relevant technology research and development.
