Abstract: A test cartridge includes a body that defines a fluid path having a specimen inlet, a diluent inlet, a reagent inlet, a reaction chamber, and an air outlet. The test cartridge includes a cover to cooperate with the body to seal the fluid path, and a membrane coupled to the body. The membrane seals the diluent inlet, the reagent inlet, and the air outlet. The cover is transparent in the region of the reaction chamber.

Abstract: An inhaler including an outlet and a plurality of sealed compartments containing medicament is disclosed. An opening mechanism is provided to open the compartment presently aligned with the outlet. An indexing mechanism sequentially aligns the compartments with the outlet. A latch is provided for latching the opening mechanism in an energized position. The latch cannot latch the opening mechanism before the indexing mechanism has aligned the next compartment with the outlet. A method of priming an inhaler and a method of dispensing a medicament from an inhaler is also disclosed.

Abstract: An inhaler, including a base having at least one air-tight, foil-sealed cavity containing medicament is disclosed. An actuator is engagable with a separating element attached to the foil, the actuator having an energized position in which it is biased towards an unloaded position so as to cause the separating element and attached foil to be moved away from the cavity. A latch has a first position, in which it latches the actuator in said energized position, wherein the latch is at least partly arranged in a flow path such that an inhalation flow through the flow path affects the latch to move from the first position to the second position. A method of dispensing a medicament from a sealed cavity inside an inhaler is also disclosed.

Abstract: A dry powder inhaler comprises a disc-shaped assembly (14) having cavities (16) filled with medicament powder for inhalation. The assembly is rotatably mounted in a housing (6, 8) on which is mounted a rotatable external casing (11, 12). A mouthpiece (10) is movably mounted on the housing (6, 8) allowing it to be brought into and out of engagement with the edge of the disc (14) whereby the mouthpiece acts as a brake to prevent or permit rotational movement of the disc (14). The inhaler is opened by rotating the housing with respect to the casing (11, 12) to expose the mouthpiece (10). As the inhaler is opened and closed, cam followers (105) on the mouthpiece move along cam tracks (109) in the casing (11, 12), causing the mouthpiece to move against or away from the disc (14). A gap is defined between the disc and mouthpiece to allow a flow of bypass air to enter the mouthpiece.

Abstract: The present invention relates to an inhaler, comprising a base having at least one air-tight, foil-sealed cavity containing medicament. An actuator is engagable with a separating element attached to the foil, the actuator having an energized position in which it is biased towards an unloaded position so as to cause the separating element and attached foil to be moved away from the cavity. A latch has a first position, in which it latches the actuator in said energized position, wherein the latch is at least partly arranged in a flow path such that an inhalation flow through the flow path affects the latch to move from the first position to the second position. The invention also relates to a method of dispensing a medicament from a sealed cavity inside an inhaler.

Abstract: A display comprises a display device having an image output surface at which an image is displayed as a spaced array of pixel elements, a light transmitting element in the form of an image guide having a viewing surface, the light transmitting element arranged to receive light from the display device and display the received light on the viewing surface, the light transmitting element having a polarising layer arranged in an optical path between the display device and the viewing surface, wherein the polarising layer is arranged to attenuate unpolarised ambient light received from outside the display while substantially transmitting polarised light received from the display device.
