Benefits of technology

[0020]The partially lidded dish is advantageous over fully open receptacles in that when air flows into the dish, it will not immediately deflect back out of the dish again. Instead, a large proportion of the breath will hit the inside of the lid. Unable to vacate the sample collector, it is caused to swirl around. Such swirling will lead to the deposition of more condensate and aerosol from the breath, into the dish itself. This gives a larger sample, and may also have more diagnostic value, since parts of the sample more easily carried by the air will be more likely to settle in the dish.
[0048]That the wand is hydrophobic will further encourage the travel of the droplets to the tip of the wand.

Problems solved by technology

Embodiment Construction

[0072]FIG. 2 shows a breath condensate collector generally indicated by 10. This embodiment is made largely of polypropylene and aluminium, both of which are robust and easy to clean. The device 10 has a chamber 12, with a breath inlet port 14 and an outlet port 16. In the present embodiment, the chamber 12 is cylindrical and has a circular cross section. The chamber also has a tapered portion 18. Other embodiments need not be cylindrical. Equally, the chamber 12 may be entirely tapered or not tapered at all. A particularly advantageous shape for the chamber 12 is a frusto-conical shape or similar, since I resiliently deformable wand may easily be designed to match the profile of the taper of the inner surface of such a chamber 12.

[0073]In this embodiment, the inlet port 14 is furthest away from the sample collector, which is a partially lidded dish 110, while the outlet port 16 is near to the partially lidded dish 110. The chamber 12 fits frictionally inside the breath condensate c...

Abstract

A breath condensate collector (10) comprising a chamber having a breath inlet port (14) and an outlet port (16); a sample collector, adapted to receive breath from the chamber outlet and having air exhaust means; cooling means (112) to promote in use condensation of vapour from breath entering the sample collector and where the sample collector comprises a partially lidded dish (110).

Description

FIELD OF THE INVENTION[0001]This invention concerns apparatus for the collection of breath condensate and also apparatus specifically for collection of breath condensate from animals, especially horses and humans.BACKGROUND AND PRIOR ART KNOWN TO THE APPLICANT[0002]Breath Condensate collectors are known. For example, application number GB 2427686 discloses, in its broadest aspect:[0003]A breath condensate collector comprising: a chamber having a breath inlet port, an air inlet port and an outlet port; a one-way valve, located in said air inlet port, to allow flow of air into the chamber, whilst resisting flow of air or breath out of the chamber; a sample collector, adapted to receive air from the chamber outlet, and having air exhaust means; cooling means, to promote, in use, condensation of vapour from breath entering the sample collector; and characterised by the feature that the flow path from the breath inlet port to the sample collector is unimpeded by a valve.[0004]Application...
