Embodiment Construction

[0085] In describing and claiming embodiments of the present invention, the following terminology will be used:

[0086] Unqualified and preceded by "the" (nouns) include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a sample" includes one or more samples.

[0087] Additionally, the term "sample" is intended to include all types of samples obtainable from exhaled air, such as gas samples, liquid samples (breath condensate), particle samples, and the like.

[0088] One embodiment relates to an apparatus for collecting a sample of exhaled air during normal breathing, the apparatus comprising a sample collector, an exhaled air receiver, and means for isolating nasal airways, wherein the apparatus further comprises:

[0089] - a sensor for detecting a change in a parameter representing a change from inhalation to exhalation and for transmitting said change as a signal;

[0090] - stream generator;

[0091] - a control unit, for...

Abstract

An apparatus for the collection of samples of exhaled air during normal respiration, comprising a flow generator, an orally insertable exhalation air receiver, and a device for isolating the nasal airways, wherein the apparatus further comprises: a sensor for detecting a change in a parameter representing the change from inhalation to exhalation and to transmit said change as a signal; a control unit adapted to receive said signal and to control said device for isolating the nasal airways; wherein the flow generator is connected to or integrated with the exhalation air receiver. A method of collecting samples of exhaled air during normal respiration conditions, comprising the steps of: detecting a change in a parameter representing the change from inhalation to exhalation and transmitting said change as a signal; receiving said signal in a control unit; activating a device for isolating the nasal airways; activating a flow generator connected to an exhalation air receiver; and collecting a sample of exhaled air during exhalation when the nasal airways are isolated.

Description

technical field [0001] The present invention relates to devices and methods for collecting samples of exhaled air under normal breathing conditions, especially for subjects who are unable to follow instructions or meet the requirements for collecting samples. Such subjects include, but are not limited to, infants and young children as well as disabled, unconscious or elderly patients. Preferably, collecting a sample of exhaled air is carried out for the purpose of determining the presence and / or concentration of a constituent in said exhaled air. Background technique [0002] It is known that there are many components in the exhaled air, which can help to give people insight into the metabolic process of some diseases, and have an indicator effect on some diseases, and even indicate the existence of the pathogenic agent of some diseases. Concentrations of this ingredient have been studied in detail in both research and clinical settings. Based on this insight, concentratio...
