For reaching the purpose of foregoing invention, the technical solution used in the present invention is: the carbon dioxide nasal oxygen tube that can detect gas concentration lwevel, comprise a conduit, one end connection universal source of oxygen joint of this conduit, through the oxygen therapy pipeline, the other end is provided with oxygen outlet, it is characterized in that: by the oxygen therapy pipeline, be fixed with side by side a carbon dioxide exhalation pipeline; And the female Luer in the carbon dioxide exit by standard is connected with the gas concentration lwevel detector, with the concentration of monitoring carbon dioxide.
The end of described oxygen therapy pipeline is that the female Luer by standard connects a section about long 2-8 centimetre of arranging, the oxygen therapy pipeline last duct occlusion end larger than leading portion oxygen catheter diameter, be respectively arranged with thereon two 0.8-2 centimeter length, that give prominence to, in order to access the oxygen suction pipe termination in patient nostril.
The above-mentioned side by side fixing carbon dioxide exhalation pipeline of setting up, its head end are that the female Luer by standard connects a section about long 2-8 centimetre of arranging, the carbon dioxide conduit last duct occlusion end larger than back segment exhale tube diameter; Be provided with two on its last duct occlusion end in order to derive the carbon dioxide exhale tube termination of carbon dioxide.About described two oxygen suction pipe terminations and two the carbon dioxide exhale tube terminations, about alignment; And described two carbon dioxide exhale tube terminations go out 3-8 centimetres than two oxygen suction pipe terminations are all short, and the carbon dioxide exhale tubes so that the carbon dioxide that patient breathes out is all breathed out are realized the more accurately monitoring of gas concentration lwevel; And its length is partially short as a token of to distinguish over two oxygen suction pipe terminations.When patient used, two pipe ends in left side inserted left nare, and two pipe ends on right side insert right naris.
Between described oxygen therapy pipeline and carbon dioxide exhalation pipeline, be provided with the active card pipe, form the head casing tube of a complete cast, and by regulating its position, the comfort level of using to be fit to different patient worn.
Described two carbon dioxide exhale tube terminations go out 3-8 centimetres than two oxygen suction pipe terminations are all short, so that the carbon dioxide that patient breathes out better all breathes out in the carbon dioxide exhale tube,
Described active card pipe rear portion also is provided with four holes and connects, so that carbon dioxide exhalation pipeline is positioned on the rectilinear direction simultaneously with the oxygen therapy pipeline.In the carbon dioxide exit, namely the afterbody that connects of two holes also is provided with the female Luer of a standard, is positioned at the carbon dioxide indicator in carbon dioxide exit, the final index that obtains the monitoring gas concentration lwevel in order to connection.
Beneficial effect of the present invention: the carbon dioxide exhalation pipeline of this carbon dioxide nasal oxygen tube by setting up, and the carbon dioxide in exit is in order to connect the gas concentration lwevel detector, accurately measure the concentration of the interior carbon dioxide of patient body of oxygen inhalation therapy, in the otherwise application such as clinical, has larger positive effect.It the most important thing is that except the effect of the oxygen inhalation therapy that plays common nasal oxygen tube it can also make the doctor in time or find as soon as possible the pathological phenomenon that part is difficult to judge, rescue time avoids delay.
