  • Publication number: 20060285987
    Abstract: A miniaturized device for pressurizing fluid. The device includes a hollow piston that provides a fluid path and a valve member. The valve member is configured for axial movement so that the valve axis remains parallel to the piston axis. The valve member is arranged at one end of the hollow piston. The valve member may be partially or completely disposed within the hollow piston. The device is particularly adapted for use in a mechanically operated atomizer to produce an inhalable aerosol of a liquid medicament without the use of propellant gas.

  • Publication number: 20060257327
    Abstract: The invention discloses a medical product for use in a treatment of respiratory disorders, and comprises a metered dose of a tiotropium dry powder formulation, directly loaded and sealed into a container made to act as a dry high barrier seal to prevent the capture and ingress of moisture into the tiotropium powder. The dose of tiotropium is further adapted for inhalation and the container is so tight that the efficacy of the dose when delivered is unaffected by moisture. In a further aspect of the invention a type of inhaler is illustrated, which may accept at least one sealed, moisture-tight container of a dose of tiotropium, to deliver the dose with a consistent fine particle dose, over the expected shelf life of the product.

  • Publication number: 20060196500
    Abstract: The invention relates to an apparatus comprising a closure-cap and a container in the form of a two-chamber cartridge in which an active ingredient and a solvent can be stored separately until the apparatus is used in a nebuliser, as well as an active substance concentrate in which the active-substance is present as a solution or suspension for storage purposes.

  • Patent number: 7090093
    Abstract: For medical fluids, two-part containers are used which consist of an inner container and an outer container which is impenetrable to diffusion. The inner container collapses when the fluid is removed. For the purposes of pressure compensation between the gaseous space, disposed between the inner- and outer containers, and the surroundings of the two-part container, a pressure compensation device is required by means of which at the same time the loss of fluid through diffusion from the collapsible inner container is kept as little as possible. To that end, at least one channel is used which communicates the gas-filled intermediate space with the surroundings of the two-part container. The time constant for compensation of a pressure differential of a few millibars is within the region of quite a few hours. It is obtained by selecting the length of the channel and channel cross-section.

  • Patent number: 7066171
    Abstract: A method for crystallizing a substance, especially an inhalable medicament, comprising the following steps: (a) dissolving said substance in a solvent, to produce a solution of said substance, (b) producing a segmented stream which consists of alternating segments of said solution of the substance and of a transport medium, (c) introducing said segmented stream into the first end of a retention stretch, which retention stretch has a first end and a second end, so that said segmented stream passes from said first end to said second end of said retention stretch, and exits from the second end of the retention stretch, (d) cooling the retention stretch, to thereby bring about crystallization of the substance in the segments of solution, in the segmented stream, as said segmented stream passes through the retention stretch, and (e) separating the crystals of material from the segmented stream as it exits from the second end of the retention stretch.

  • Publication number: 20060027233
    Abstract: A nebulizer for a fluid and a container holding the fluid which is insertable in the nebulizer are proposed. To improve safety in use it is proposed that the nebulizer comprises first coding means and the container is associated with second coding means, so that the container can only be inserted in the nebulizer or used therewith if the codes match. Preferably, the code associated with the container comprises clear identification of the fluid contained in the container.

  • Publication number: 20060016449
    Abstract: For meteredly dispensing a liquid over a period of several months from a container which can be stored over a long period of time, the need is for a container which is practically diffusion-tight and in which the liquid does not come into contact with the ambient atmosphere. The cartridge according to the invention is a three-shell container comprising a collapsible bag which contains the liquid, a container which is stable in respect of shape and a stiff metal casing. The cartridge can be releasably connected to a dispensing device. The cartridge can be provided with a micro-opening with which the time for pressure equalisation between the cartridge and the ambient atmosphere can be adjusted. The cartridge is suitable for aqueous and for alcoholic liquids which contain a pharmaceutically active substance. The liquid in the cartridge is protected from external influences. The cartridge can be used in an atomiser for producing an inhalable aerosol for the treatment of illnesses.

  • Publication number: 20050247305
    Abstract: A nebulizer having an insertable container and a monitoring device for counting actuations of the nebulizer is proposed. The monitoring device is mounted in a detachable housing part and directly detects movements of container during a nebulizing process, an air supply current in the region of a mouthpiece, and/or the production of aerosol, in order to detect this as the actual dispensing of fluid and actuation of the nebulizer, while preferably the time of actuation of the nebulizer is additionally detected and stored. This allows better monitoring and guidance for the user.
