The invention discloses a multi-cavity oxygenator with a liquid separation and drainage structure, and belongs to the technical field of medical instruments. The oxygenator comprises an oxygenation chamber, a space occupying column and a temperature changing chamber. The space occupying column extends in the axis direction of a flow dividing channel. A plurality of oxygenation areas are further arranged in the oxygenation chamber. Liquid dividing holes are formed in the flow dividing channel, so that the flow dividing chamber is communicated with the oxygenation areas. By means of the space occupying column, before blood enters the oxygenation areas after passing through a heat exchange chamber, the blood enters the flow dividing channel to be divided in multiple directions and then enters the flow dividing chamber, the uniformity of flow distribution of the blood in the oxygenation chamber is guaranteed, and liquid retention and flowing dead zones are not prone to being generated. The plurality of oxygenation areas uniformly disperse venous blood to form a plurality of independent gas exchange units, so that full contact of the venous blood and membrane wires for ventilation is realized, efficient oxygenation and carbon dioxide removal performance is guaranteed, blood oxygenation flow paths are reduced, transmembrane pressure difference is reduced, gas exchange performance is improved, and better comprehensive performance is provided.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-chamber oxygenator with a liquid separation and drainage structure. Background technique [0002] Extracorporeal circulation device for clinical operation, commonly known as artificial lung, also known as oxygenator. As an extracorporeal blood oxygenation device, an oxygenator plays an important role in cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenation (ECMO). In the application process, its main function is to convert oxygen-poor venous blood into oxygen-rich arterial blood, so the oxygen exchange performance is very important. In addition, due to the existence of non-biological surfaces and non-physiological blood flow conditions, blood compatibility also needs attention, and the pressure drop through it is very important. [0003] However, it should be noted that, in general, in order to increase its oxygen exchange performance, it is neces...
