Abstract: A method for producing a cartridge is proposed, where a fluid is filled into an opening of a container and a closure part is inserted into the container, thereby moving a movable piston arranged within the container.

Abstract: A cartridge and a nebulizer for nebulizing a fluid as well as a method for fluidically connecting the cartridge to the nebulizer are proposed. The cartridge comprises a closure with a valve, wherein the valve displaces fluid into the nebulizer when opened. Further, the cartridge forms two axially spaced sealings with the nebulizer when connected.

Abstract: A container, a nebulizer and a use of an indicator device are described, where the container comprises an indicator device fixedly mounted on the bottom of the container, the container is arranged within the nebulizer and the container can be detached by grabbing the indicator device.

Abstract: A nebulizer for nebulizing a liquid from a container includes a fluid pump for withdrawing the liquid in doses from the container and pressurizing the respective doses for nebulization. The nebulizer includes in addition an air pump with a piston/cylinder arrangement for pumping air into the container to pressurize the liquid in the container to help withdrawing the liquid from the container.

Abstract: A nebulizer for nebulizing a fluid from a cartridge and a cartridge for such a nebulizer is proposed. The cartridge comprises a container containing the fluid to be nebulized and is fluidically connected to the nebulizer by inserting a connecting element of the nebulizer for conveying the fluid out of the container. The cartridge is preferably adapted to sealingly receive the connecting element and can optionally comprise a membrane or sealing wall which seals the cartridge initially and is piercable or breakable by the connecting element upon insertion. The cartridge can further comprise an at least partially flexible and/or bendable tube for conveying the fluid out of the container. The tube is preferably wettable with the fluid and/or comprises an at least partially hydrophilic and/or polar surface. Further, the tube can at least partially be shaped as a helix.

Abstract: A foil-cutting device is disclosed for opening a foil protecting a dose of medical power carried by a dosing cassette or the like for an inhaler device. The dosing cassette will in a typical embodiment carry a number of prepared doses (31), which for protection of the medical powder are covered by a metallic or plastic foil (24). The foil-cutter device of the present invention provides a tool (11) for accessing a selected sealed dose of medical powder of the cassette during an inhalation process using a dry powder inhaler (DPI). When a user inhales through the DPI the foil-cutter opens the foil (24) for access to a pre-metered powder dose (31). The foil-cutter arrangement ensures that no access is permitted to the pre-metered dose during any other circumstances. Particularly the present invention is adapted to be applied in an inventive continuous inhaler prolonging the release of a powder dose during the inhalation of the medical powder.

Abstract: An arrangement is disclosed for, in connection to an inhalation operation, opening and closing an air inlet of a dry powder inhaler device (DPI) provided with a pre-metered dosing member (4). The arrangement requires a certain well-defined minimum pressure differential between a surrounding atmosphere and the airways of the inhaling person to open the inlet for outside air to enter into the interior of the DPI. The arrangement controlling the opening and closing of the air inlet presents a biased flap connected to a biased catch mechanism. The biased flap (16) closes the air inlets (23) of the DPI to the atmosphere by the force exerted by a compression spring (13), which acts on the flap through a mechanism of levers. In order to open the flap a force Fp bigger than the closing force Fc of the spring and lever mechanism must be applied. The necessary force ensues from the pressure differential across the flap resulting when sucking the mouthpiece of the DPI to a certain degree.

Abstract: An interface arrangement is disclosed for ensuring proper dosing as well as achieving a safe operation and handling of a dry powder inhaler (DPI) used for administration of a powder to be inhaled. The interface of the present invention primarily handles the loading of a cassette (4) carrying pre-metered doses into the dry powder inhaler (8). An important characteristic is that the interface by utilizing a particular coding prevents a user from loading a cassette not containing the proper powder. Additionally the interface informs a user when a new mouthpiece has to be replaced after being used for a pre-defined number of inhalation operations. Additionally the interface informs a user when a present cassette has delivered its last dose and should be exchanged. Also information on the number of further cassettes already utilized will control that another cassette still is permitted to be loaded.
