Description

Oxygen supply device in a kind of venous lumen

Technical field

The utility model is related to artificial oxygen therapy field, and in particular to oxygen supply device in a kind of venous lumen.

Background technology

It is well known that the deposit of oxygen is little in human body, it is necessary to which continuously feeding oxygen in a steady stream from the external world can just sustain life, Therefore nose conduit, hyperbaric oxygen chamber and Ventilators occurred in succession after from clinically initial mask oxygen inhalation etc. are all It is conceived to by respiratory tract oxygen supply, and has turned into the important means that various anoxics are given treatment to.However, for some particular patients 's, often Rule oxygen supply method can seem helpless.Such as face due to ALI, traumatic caused by Serious respiratory tract burn etc. Hypertonicity pulmonary edema, SARS etc. cause the patient of pulmonary diffusion function serious hindrance caused by hydropneumothorax, seawater, and its subject matter is simultaneously Dysfunction of ventilation is not lain in, therefore the life of patient usually can not be effectively saved through conventional respiratory tract oxygen supply；Meanwhile, it is special at some In the case of, the rescue limited also to patient of conventional oxygen supply method brings many obstacles.So, oxygen supply approach can be changed, Attempt to be used as supplemental oxygen new method by vein even oral wait, bypass this pass of the alveolar of diffusing capacity and make oxygen straight Tap into blood

In fact recent domestic never has stopping about the research in terms of oxygen carrying substitute, such as without matrix blood egg In vain, genetic engineering artificial blood, circulating protein solution, the perfluor carbon solution of liposome parcel etc., but due to these product process It is complicated, expensive, there is relatively large distance from technology maturation so far, be still difficult to use in clinic.And once should be used in China Liquid oxygen charging method then includes light quantum blood therapy (UIB), blood-magent therapy, magnesium arginyl amine hydroperoxide Carbamide Peroxide method, light quantum Liquid is treated etc., but is also respectively present blood drawing oxygenation and is fed back some defects such as the few, less stable of loaded down with trivial details, the blood oxygen carrying content of operation.
