Description
Technical field
The present invention relates to method is closed and in particular to a kind of oxygen closes drainage tube, oxygenation device and oxygen in oxygenation field.
Background technology
It is known that in human body, the deposit of oxygen is little just can sustain life it is necessary to continuously feed oxygen in a steady stream from the external world,
Therefore from clinically initial mask oxygen inhalation to nose conduit, hyperbaric oxygen chamber and the Ventilators in succession occurring afterwards etc. all
It is conceived to by respiratory tract oxygen supply, and become the important means of various anoxia treatments.However, for some particular patients ', often
Rule oxygen supply method can seem helpless.Acute lung injury, traumatic such as in the face of being caused due to Serious respiratory tract burn etc.
Hypertonicity pulmonary edema that hydropneumothorax, sea water cause, SARS etc. cause the patient of pulmonary diffusion function serious hindrance, and its subject matter is simultaneously
Do not lie in dysfunction of ventilation, therefore usually cannot effectively save the life of patient through conventional respiratory tract oxygen supply；Meanwhile, special at some
In the case of, the restriction of conventional oxygen supply method also brings many obstacles to the rescue of patient.So, oxygen supply approach can be changed,
Attempt being used as supplemental oxygen new method by even oral grade of vein, bypass this pass of alveolar of diffusing capacity and make oxygen straight
Tap into into blood？
In fact recent domestic never has and stops about the research of oxygen carrying succedaneum aspect, such as no substrate blood egg
In vain, genetic engineering artificial blood, the circulating protein solution of liposome parcel, perfluor carbon solution etc., but due to these product process
Complicated, expensive, also have 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 treatment etc., but be also respectively present blood drawing oxygenation and feed back some defects such as loaded down with trivial details, the few, less stable of blood oxygen carrying content of operation.
Content of the invention
The present invention is to solve the above problems, and provides a kind of oxygen to close drainage tube, oxygenation device and oxygen and closes method.
The technical problem to be solved to be realized using following technical scheme：
A kind of oxygen closes drainage tube, and this oxygen closes drainage tube and is made up of and both central axis weights outer layer sleeve and inner layer sleeve
