Abstract

The invention relates to a membrane-type oxygen exchange device. The membrane-type oxygen exchange device is used for removing carbon dioxide in blood and enriching oxygen in the blood, and comprises a hexahedron housing and a core mounted in the housing, wherein the bottom and the corresponding top of the hexahedron housing are provided with a venous blood inlet and an arterial blood outlet respectively, and a set of opposite sides of the hexahedron housing are provided with an oxygen inlet and a carbon dioxide outlet respectively; the core is a hollow semipermeable membrane fiber bundle formed by a plurality of semipermeable membranes, and one end of each semipermeable membrane is communicated with the oxygen inlet while the other end of each semipermeable membrane is communicated with the carbon dioxide outlet; the outer surface of each semipermeable membrane is coated with a heparin coating, and the blood enters the housing through the venous blood inlet, and undergoes blood oxygen exchange with oxygen which enters the semipermeable membranes from the oxygen inlet; produced carbon dioxide is discharged from the carbon dioxide outlet, and the blood which completes the blood oxygen exchange is discharged from the arterial blood outlet. According to the membrane-type oxygen exchange device, the formation of thrombus in the blood can be effectively inhibited, and the gas exchange efficiency is improved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a membrane-type oxygen exchange device for removing carbon dioxide in blood and enriching oxygen in blood in extracorporeal blood circulation, and is mainly used for treating heart or lung diseases. Extracorporeal circulation assistance and extracorporeal membrane oxygenation are required. Background technique [0002] Membrane oxygenator is a medical device that stops the beating of the heart and replaces the function of the lungs. It has the function of regulating the oxygen and carbon dioxide content in the blood. At present, the most common membrane oxygenator on the market mainly performs gas exchange of blood through the semipermeable membrane. When the blood contacts the semipermeable membrane, it is easy to cause blood coagulation reaction and thrombosis; Low, gas exchange with conventional semipermeable membranes is likely to lead to incomplete gas exchange, resulting in ...
