    Abstract: The invention as disclosed herein provides a breath-condensate analysis cartridge suitable for incorporation into an exhalation device. The cartridge comprises a condensation zone to receive exhaled breath, the condensation zone having a peripheral region. An analysis chamber is included in which a condensed breath sample is analyzed. The surface of the condensation zone acts. to create a fluid flow path in the peripheral region. A fluid flow path through the peripheral region links the condensation zone to the analysis chamber. A lip at least partially covers the peripheral region, the lip co-operating with the condensation zone to form a capillary to control fluid flow.

    Abstract: A mouthpiece is disclosed through which a user inhales and exhales when providing an exhaled breath sample. The mouthpiece includes a mouth-engaging element about which a user places their mouth when using the mouthpiece and also a housing having a housing wall. The housing wall defines a first aperture through the housing wall, the first aperture being linked by a conduit defining a first fluid flow path to the mouth-engaging element. Interposed therebetween is a first directional valve, allowing air into the mouthpiece from atmosphere. A second conduit is provided, defining a second fluid flow path from the mouth-engaging element, and directing exhaled air out of a second aperture of the mouthpiece. The second conduit houses a second directional valve housed within the second fluid flow path.

    Abstract: The device as disclosed herein is to measure breath humidity, the device comprises an inlet fluidly connected at a first end of a tubular body, said tubular body defining an inner tube volume. The device further comprises a condenser plate, fluidly connected to the second end of the tubular body to receive exhaled breath. A partition wall intermediate the first and second ends divides the inner tube volume into first and second chambers, the second chamber providing fluid access to the condenser plate. The wall has a one-way valve therethrough allowing breath from the first to the second chamber. The device further comprises one or more apertures in the tubular body wall of the first chamber, the or each aperture fluidly linking a sensor to the first chamber, and a relative humidity sensor fluidly linked to the second chamber.

    Abstract: An analyser for collecting and analysing a breath condensate is disclosed. The analyser comprises a housing and a cartridge device (10). The device comprises a condensation zone (12) to condense exhaled breath from a subject and cooling means operably connected to the condensation zone (12). The device includes further discrete regions (13) for detection of analyte and measurement of analyte. The condensation zone (12) has a fluid exit connecting the condensation zone (12) to the discrete regions (13). The analyser includes a mouthpiece which is provided with a plurality of chambers configured to cause a change of 90° in the direction of the exhaled breath in order to trap saliva aerosols.
