Abstract

The invention relates to an apparatus for collection of airway gases from a subject comprising a first means for producing closure of the velum of the subject, and a second means for collection of the airway gases, wherein the first and second means need not be integral with each other.

Claims

1. An apparatus for the collection of airway gases from a subject, comprising:

a) first means for producing closure of the velum of the subject; and

b) second means for collection of the airway gases.

7. A method or apparatus for the analysis of airway gases, wherein:

a) gases are collected according to any preceding claim; and

b) the concentration of one or more of the gases or components thereof is determined.

8. The method or apparatus according to claim 7, wherein the concentration of NO is determined.

2. A method of collecting nasal gas from a subject, comprising the steps of:

a) producing closure of the velum of the subject; and

b) collecting nasal gases, the gases preferably being collected by i) aspiration of nasal gases, or ii) nasal insufflation.

3. A method of simultaneously collecting gases from a subject from the lower airway and the nasal airway, comprising the steps of:

a) producing closure of the velum of the subject;

b) collecting exhaled gases from the airway; and

at the same time

c) collecting nasal gases, the gases preferably being collected by i) aspiration of nasal gases, or ii) nasal insufflation.

4. An apparatus for collection of exhaled gas condensate from a subject, comprising:

a) first means for producing closure of the velum of the subject;

b) second means for collecting exhaled gases; and

c) third means for causing condensation from the exhaled gases.

5. An apparatus for collection of nasal gas condensate from a subject, comprising:

a) first means for producing closure of the velum of the subject;

b) second means for aspirating nasal gases; and

c) third means for causing condensation from the nasal gases.

6. A method for simultaneously collecting gases from nasal cavities and lower airways of a subject in series, comprising the steps of:

a) producing closure of the velum of the subject;

b) collecting exhaled gas; and

at the same time

c) insufflating nasal cavities with exhaled gas; and

d) collecting gas from the nasal cavities.

9. A method or apparatus substantially as hereinbefore described with reference to any of the accompanying drawings.
