Description
Technical field
The expiratory air acquisition component that the utility model relates to a kind of expiratory air harvester for off-line collection expiratory air and uses in the apparatus.
Background technology
The collection of expiratory air serves many purposes, as the NO level in expiratory air can reflect the airway inflammation level of object to be measured to a certain extent; CO level in expiratory air can reflect the smoking state etc. that object to be measured is recent.In addition, expiratory air is monitored as biological sample, have gather convenient, without wound, can the features such as continuous several times sampling, experimenter be more acceptant.Meanwhile, the component of expiratory air and analytic process are all comparatively urinated, blood is more simple, and the analysis of therefore expiratory air detects and also gradually obtains social extensive concern.
At present, the method gathering expiratory air is divided into two kinds, and one is online acquisition method, namely uses baroque online expiratory air measurement mechanism, on-line measurement and analysis are carried out to expiratory air in scene, and these online expiratory air measurement mechanisms are generally main equipment and not easily carry; Another kind is off-line acquisition method, collects in special expiratory air collection bag, then carry out off-line analysis to the expiratory air in expiratory air collection bag by expiratory air.Relative to online acquisition method, off-line collection has multiple advantage, as: the acquisition time that off-line gathers needed for expiratory air is shorter; Secondly, off-line collection expiratory air can be measured in multiple place easily; Finally, off-line gathers expiratory air and can once measure multiple sample, and the efficiency of measurement is higher.
But off-line gathers the impact that expiratory air is subject to the associated gas in air, and as the NO in expiratory air can be subject to the impact of the NO gas in air, the CO in expiratory air can be subject to the impact etc. of the CO gas in air; This external off-line gathers in the process of expiratory air, after requiring object to be measured dark air-breathing to total lung capacity, (ground of not feeling suffocated) exhales to lung residual immediately, in the process, if object to be measured is not exhaled immediately, and there is the phenomenon of feeling suffocated, certain impact may be produced on the accuracy of the content of gas in the expiratory air of off-line collection to a certain extent.
Currently available technology mainly takes two kinds of modes to control above problem, the first exhales after allowing object to be measured directly suck air in the process of off-line collection expiratory air, the impact of associated gas in air, the content of associated gas in air is measured simultaneously, correct with the measurement result of the content of the associated gas in air to expiratory air, but this kind of scheme, when the content of aerial associated gas is higher (as being greater than 100ppb), larger on the impact of the accuracy of the content of gas in expiratory air; Second method is in expiratory air gatherer process, exhale to expiratory air collection bag again after allowing object to be measured directly suck air by gas filter, but this kind of method can not ensure that object to be measured is exhaled immediately to expiratory air collection bag after air-breathing, in the alternation procedure of air-breathing and expiration, can be there is the phenomenon of feeling suffocated of certain hour in object to be measured, and then produce certain impact to the accuracy of the measurement result of gas content in expiratory air.
