Venous membrane oxygenation device and oxygenation method

Abstract

A vein film type oxygenation device and an oxygenation method are provided. A vein film type oxygenation device comprises a vein oxygenation tube inserted into a vein blood vessel, and a control device connected with a tube end extending of the vein oxygenation tube and extending out of the vein blood vessel, wherein the control device can precisely control oxygen flow amount introduced to the vein oxygenation device; a longitudinal section of the vein oxygenation tube can be divided into a vein oxygen feeding tube and an output tube via a semi-transparent film; the semi-transparent film allows air rather than blood to pass; with the vein oxygenation tube inserted into the vein blood vessel, oxygen can directly enter the blood and oxygenates with hemoglobin while passing by a pulmonary alveoli with dispersion function impediment, so the vein oxygenation tube can better replace a lung part upon lung nonfunction or temporary oxygenation failure; compared with a film type oxygenator, an oxygen-carrying substitute or a liquid oxygenating method, the vein film type oxygenation device is simply structured, can be conveniently used; introduction of blood outside a human body can be unnecessary, so various possible infections can be avoided, and great blood-oxygen content and stability can be achieved.

Description

technical field [0001] The invention relates to the field of artificial oxygenation, in particular to a venous membrane oxygenation device and an oxygenation method. Background technique [0002] As we all know, the oxygen reserves in the human body are very small, and oxygen must be continuously supplied from the outside to maintain life. It is used to supply oxygen through the respiratory tract, and has become an important means of treating various hypoxia. However, for some special patients, conventional methods of oxygen administration will appear powerless. For example, in the face of patients with acute lung injury caused by severe respiratory burns, traumatic fluid pneumothorax, hyperosmolar pulmonary edema caused by seawater, SARS, etc., the main problem is not the ventilation barrier. Conventional respiratory oxygen supply is often unable to effectively save the patient's life; at the same time, in some special cases, the limitation of conventional oxygen supply m...

Problems solved by technology

[0003] In fact, research on oxygen-carrying substitutes at home and abroad has not stopped in recent years, such as stroma-free blood protein, genetically engineered artificial blood, circulating protein solution wrapped in liposomes, perfluorocarbon solution, etc., but due to the complex process of these products , the price is expensive, and there is still a long way to go before the technology is mature, and it is still difficult to be used in clinical practice

The liquid oxygenation methods that have been used in my country include optical quantum blood therapy (UIB), blood magnetic therapy, oxygenation method in carbonic acid amide hydrogen peroxide, optical quantum liquid therapy, etc., but there are also blood pumping and oxygenation reinfusion operations. Some defects such as cumbersome, low blood oxygen carrying capacity, and poor stability
