Abstract: An inhaler comprises a pump 17, a drug dosing device 15 and a cyclone 1 which delivers an aerosol of powdered medicament from the drug dosing device 15 into a chamber 11 when the pump 17 is activated. The aerosol is inhaled by the user through a mouthpiece 13.

Abstract: A device for dispensing single doses of powdered medicament has a housing for holding a container which has a number of sealed apertures containing individual encapsulating doses of medicament. The container can move relative to the housing to allow each aperture in succession to be brought into registry with an airway which communicates with a mouthpiece. The device includes a piercing member, such as a pin, which can be inserted into a selected aperture to break its respective seals. The configuration and movement of the pin are such that this action expels substantially no powder from the aperture.

Abstract: The vehicle comprises a sample receiving reservoir (15), a plurality of test stations each comprising an FCFD or other capillary fill sensor cell (3), and passage (22) for providing fluid communication between the reservoir and a conduit with which end portions of said cells communicated such that in use sample from the reservoir may be fed to the plurality of cells substantially simultaneously. The vehicle makes it easier to know time zero for each assay. Passage (22) providing fluid connection may comprise at least one pore in a wall of the reservoir, the or each pore being of a size such that surface tension of the liquid normally prevents escape of ligand. Rotation of the vehicle breaks surface tension and liquid is released into the conduit.
