Embodiment Construction

[0027] To make the purposes, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1 to Figure 8 As shown, an oxygenator includes: a casing 20 , a membrane group ( 10 ) disposed in a cavity of the casing 20 , a first sealing part 16 and a second sealing part 34 .

[0029] The membrane group 10 includes a plurality of flat membrane units 17 and a plurality of hollow fiber membrane groups arranged alternately, such as Figure 7 and Figure 8 shown. The flat membrane unit 17 is a single-layer flat membrane, and the hollow fiber membrane group includes the heat-exchangeable hollow fiber membrane unit 14 and the oxygenated hollow fiber membrane unit 15 (such as Figure 4 and Figure 5 ), the heat-exchangeable hollow f...

Abstract

The oxygenator comprises a shell, and a membrane group, a first glue sealing part and a second glue sealing part which are arranged in a cavity of the shell, the membrane group comprises a plurality of flat membrane units and a plurality of hollow fiber membrane groups which are alternately stacked, and each hollow fiber membrane group comprises a heat exchange hollow fiber membrane unit and an oxygenation hollow fiber membrane unit which are arranged in parallel; on the two sides of the hollow fiber opening, the second glue sealing part is used for sealing the outer edges of the plurality of flat sheet membrane units and the plurality of hollow fiber membrane groups which are arranged in a stacked manner; the first glue sealing part is parallel to the longitudinal axis of the hollow fiber membrane tow and is sequentially sealed on the edges of the two adjacent flat sheet membrane units which are arranged in a laminated manner, the two adjacent flat sheet membrane units subjected to glue sealing form a flat sheet membrane group, and every two adjacent flat sheet membrane groups are separated by a layer of hollow fiber membrane group. The oxygenator is matched with the flat sheet membrane units and the hollow fiber membrane groups which are arranged in a crossed and laminated manner through the glue sealing part, so that the gas exchange area is increased, the gas-blood exchange efficiency can be effectively improved, and the treatment rate is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an oxygenator and a preparation method thereof. Background technique [0002] Extracorporeal membrane oxygenation (ECMO) is an extracorporeal circulatory system with both cardiac and pulmonary auxiliary functions. a barrier. Membrane oxygenator, also known as artificial lung, is the key core device in ECMO system, which is used to replace lung function to oxygenate blood and expel carbon dioxide. [0003] Although ECMO membrane lungs currently used in clinical treatment have treated many patients, there are still shortcomings such as low gas-blood exchange efficiency with oxygenated membrane filaments, easy blood coagulation to cause thrombosis, and pipelines easily polluted, requiring frequent replacement of consumables. Therefore, it is necessary to develop a new type of membrane oxygenator technology to improve the oxygenation efficiency of blood and provide more efficient and...
