Abstract

The invention relates to a membrane structure and a membrane-type oxygenator. The membrane structure includes multiple first hollow fiber layers and multiple second hollow fiber layers arranged with the first hollow fiber layers in a staggered mode, and each first hollow fiber layer and each second hollow fiber layer are provided with a plurality of hollow fiber pipes arranged in an annular mode respectively; the section of each hollow fiber pipe has a minimum circumscribed circle and a maximum inscribed circle; each hollow fiber pipe of each first hollow fiber layer forms an included angle with each hollow fiber pipe of the corresponding adjacent second hollow fiber layer. According to the membrane structure and the membrane-type oxygenator using the membrane structure, the membrane structure can effectively reduce pre-loading volume of blood, and decrease the blood pressure to avoid damage to the blood; shunting of the blood can be achieved to make the blood form a thin blood membrane, increase the contact area between the blood and oxygen, and improve the oxygenation efficiency of the blood and the oxygen.

Description

technical field [0001] The invention relates to the technical field of medical device products, in particular to a silk membrane structure and a membrane oxygenator using the silk membrane structure. 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. The principle of the membrane oxygenator is to draw the venous blood in the body out of the body, exchange oxygen and carbon dioxide into arterial blood after passing through the membrane oxygenator, and then reinfuse the patient's arterial system to maintain the supply of oxygenated blood to the organs and tissues of the human body. During the operation, it temporarily replac...
