    摘要： A collection device (10), such as a mask, for collecting constituents of interest present in an airstream exhaled by a subject The collection device comprises a support member (12) mountable external to the nose and/or mouth of the subject, and at least one collection region (13) mounted to the support member (12) for collecting at least some of said constituents. The constituents are collected in a manner that allows subsequent analysis of the constituents. When the support member (12) is mounted over the nose and/or mouth of the subject, at least some of the exhaled airstream passes through the at least one collection region (13).

    摘要： A diagnosis method for respiratory disease based on the separation of the expired airway phase in an exhaled breath from the alveolar phase, and a device to accomplish the method. The device includes a cartridge assembly and a disposable condensing chamber carried in a substantially enclosed housing. The cartridge assembly includes a disposable cartridge and a reusable control system that monitors a characteristic of gas passing through the cartridge to determine when to divert the exhaled breath to an exhaust outlet and when to divert the exhaled breath to the condensing chamber. The characteristic is selected as being representative of the transition from the expired airway phase to the alveolar phase. Also included are a refrigeration system, an auxiliary monitoring system for determining when a sufficient volume of gas has been produced, and a built-in analyzer.

    摘要： The invention provides a method for the rapid assessment of the degree of halitosis comprising the steps of a) obtaining a sample of fluid and/or tissue from the oral cavity of a subject, b) assessing the amount of null-galactosidase in said sample, c) determining the degree of halitosis in said subject, by comparing the result obtained in step b) with appropriate reference values.

    摘要： A breath test for diagnosing the presence of Helicobacter pylori in a subject is described. The method of diagnosing Helicobacter pylori is performed as follows. First, a safe and effective amount of urea, preferably appropriately labelled, is administered to the subject. Second, a plurality of the exhaled breaths of the subject is analyzed to detect the concentration of a cleavage product or products, produced when urease cleaves the substrate. The measured concentrations are then fitted to a curve, and the derivative is then calculated, to indicate the presence or absence of Helicobacter pylori infection in the subject.
