Endovenous oxygen transporting device and oxygen transporting method

Abstract

The invention discloses an endovenous oxygen transporting device and an oxygen transporting method. The oxygen transporting device comprises a vein oxygen catheter which is inserted in a vein, and a control device which is connected to the end, extending out the vein, of the vein oxygen catheter, wherein by virtue of the control device, an oxygen concentration supplied into the vein oxygen catheter can be precisely controlled. Oxygen is transported to the vein by virtue of the vein oxygen catheter which is inserted in the vein, and the oxygen, bypassing alveolus pulmonis having diffusion dysfunction, directly enters blood and oxygenates with hemoglobin, so as to better replace a lung in the case that lung failure occurs or an oxygenating effect cannot be developed temporarily; in comparison with a membrane oxygenator, an oxygen-carrying substitute or a liquid oxygen filling method, the device is simple in structure, convenient to use and capable of preventing in vitro drainage of the blood, so that various possible infections are avoided; and the device is high in blood-carrying-oxygen content and relatively good in stability.

Description

technical field [0001] The invention relates to the field of artificial oxygen delivery, in particular to an oxygen delivery device in a vein cavity and an oxygen delivery method thereof. 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 conven...

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
