Membrane oxygenator with high-efficiency gas-fluid exchange

Abstract

The invention provides a membrane oxygenator with high-efficiency gas-fluid exchange. The membrane oxygenator mainly comprises parts including a carbon discharge chamber, an oxygenation chamber, a temperature control chamber, a vacuum pump, a pure oxygen cylinder, a flow meter and the like. When flowing through a hollow silicone hydrogel tube placed in the carbon discharge chamber, venous blood drained from a human body permeates a tube wall to release carbon dioxide into a chamber body; a vacuum pump is utilized to apply micro-negative pressure to the carbon discharge chamber, so that the carbon dioxide is efficiently discharged; then the blood flows into a hollow silicone hydrogel spiral tube placed in the oxygenation chamber, and the pump is utilized to apply micro-positive pressure tothe oxygenation chamber, so that oxygen enters the blood efficiently and is combined with red blood cells; and the carbon discharge chamber and the oxygenation chamber are both placed in the temperature control chamber. The membrane oxygenator of the invention performs discharge of the carbon dioxide and absorption of oxygen in the blood step by step, and supplemented by a moderate negative pressure environment and positive pressure environment, the gas-fluid exchange efficiency can be effectively improved, the situation that acral necrosis of a patient is caused by using an existing oxygenator for long term to threaten life is avoided, the treatment rate is increased and sequelae are reduced.

Description

technical field [0001] The product relates to the technical field of medical device products, in particular to a membrane oxygenator for enhancing gas-liquid exchange. Background technique [0002] Membrane oxygenator is an artificial lung, a medical device used to replace the lung. It has the function of regulating the oxygen and carbon dioxide content in the blood. The principle of the membrane oxygenator is to lead the venous blood in the body out of the body, exchange oxygen and carbon dioxide through the membrane oxygenator, and then return it to the patient's arterial or venous system to maintain the supply of oxygenated blood to human organs and tissues, acting as a substitute. The role of normal human lungs, while providing doctors with a quiet, blood-free and clear operating environment to facilitate the implementation of surgery. [0003] The use of extracorporeal membrane oxygenation (ECMO) has achieved certain results in the field of clinical emergency and criti...
