Abstract

The invention discloses an membrane oxygenator with a built-in filter. The membrane oxygenator comprises an upper cover, a lower cover, a shell and an oxygenation structure, the two ends of the shell are connected with the upper cover and the lower cover respectively, the oxygenation structure is arranged in the shell, and the oxygenation structure sequentially comprises a mandrel, a filter screen, an oxygen pressure membrane and a temperature changing membrane from the center to the outside. Blood flows in from a blood inlet in the upper side of the membrane type oxygenator, sequentially transversely penetrates through a variable-temperature membrane, the oxygen pressure membrane and the filter screen and then flows out from the blood outlet in the lower portion of the mandrel, in the process that the blood transversely passes through the variable-temperature membrane, the oxygen pressure membrane and the filter screen, the flow speed of the blood is gradually decreased, the blood makes full contact with the oxygen pressure membrane and the filter screen, and the oxygenation effect and the filtering effect of the membrane type oxygenator can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a membrane oxygenator with a built-in filter. Background technique [0002] Membrane oxygenator is a medical device that stops the heart and replaces the lungs. It has the function of regulating the oxygen and carbon dioxide content in the blood. It is an essential medical equipment for cardiovascular surgery, and it is also necessary for the treatment of acute respiratory diseases and the stage of waiting for lung transplantation. medical equipment. According to the principle of alveolar gas exchange, the membrane oxygenator integrates the functions of oxygenation, temperature change, blood storage and filtration. Carbon dioxide is exchanged into arterial blood, and then reinfused into the human arterial system to maintain the supply of oxygenated blood to human organs and tissues, and temporarily replace the lung function during the operation to meet the needs of patie...
