Embodiment 1

[0028] refer to figure 1 and figure 2 , the present embodiment provides an extracorporeal membrane oxygenator, comprising: a casing 10 and a gas exchange unit 20, the interior of the casing 10 forms an oxygenation chamber, and the oxygenation chamber has a blood channel and blood inlets located at both ends of the blood channel. Port 111, bleeding port 121; the oxygenation chamber also has an oxygen channel and an air inlet 131 and an air outlet 132 located at both ends of the oxygen channel. In actual use, blood and oxygen pass through the blood channel and the oxygen channel respectively, the oxygen in the oxygen channel enters the blood in the blood channel through the gas exchange unit 20, and the carbon dioxide in the blood passes through the gas exchange channel through the blood channel. The unit 20 enters the oxygen channel and exits through the gas outlet 132. The gas exchange unit commonly used in existing oxygenators is a whole. This design method makes the lengt...

Abstract

The invention provides an extra corporeal membrane oxygenation device which comprises a shell and at least two gas exchange units. An oxygenation chamber is formed in the shell and internally provided with a blood channel, a blood inlet and a blood outlet, and the blood inlet and the blood outlet are located in the two ends of the blood channel. The oxygenation chamber is further internally provided with an oxygen channel, a gas inlet and a gas outlet, and the gas inlet and the gas outlet are located in the two ends of the oxygen channel. Each gas exchange unit is woven into a preset shape through polymer fiber tubular products and is fixedly arranged in the oxygenation chamber and close to the blood channel and the gas channel so that oxygen in the gas channel can penetrate through the gas exchange unit to enter the blood channel. By arranging the two gas exchange units, in the production and manufacture process, the length of applied single fiber tubes can be reduced by half, and therefore the process difficulty of production and manufacture is lowered, and fiber tubes can be easily woven into the preset shape.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an extracorporeal membrane oxygenation oxygenator structure. Background technique [0002] Extracorporeal Membrane Oxygenation (ECMO) is an "artificial lung" outside the human body. It mainly plays a role in replacing part of the lung function. Self-repair, maintain the oxygenated blood supply of human organs and tissues, so as to effectively maintain the signs of life and provide enough time for subsequent treatment of damaged organs. The oxygenator is the core device of the portable lung function support device. [0003] The oxygenation chamber of the commonly used oxygenator for extracorporeal respiratory support is usually equipped with an integral gas exchange unit, such as a portable pumpless extracorporeal membrane oxygenator disclosed in Chinese patent CN202459508U. There are the following technical defects: since the gas exchange unit adopts an integrated struc...
