  • Publication number: 20040258625
    Abstract: A method as well as a therapeutic metered combined dose are disclosed for a combined administration of medicinal dry powders. A metered medicinal dry powder combined dosage comprising at least two medicaments of separate dry powder formulations is prepared, whereby the metered powder quantity per medicament is deposited in a dose forming step creating the medicinal combined dose. The deposits of the at least two medicaments are suitably kept separated from each other, such that the medicaments cannot detrimentally interact after forming of the combined dose, and the medicinal combined dose is introduced into an inhaler device for a delivery of the powder dose during the course of a single inhalation.

  • Patent number: 6722365
    Abstract: A powder distribution device for transporting and mixing a fine powder with a gas is disclosed. The device presents a distribution member forming a connection between a source of fine powder and a discharge opening. The distribution member has a first inlet portion (10) and an outlet portion (12) for a stream of a first gas (1) mixed with the fine powder. The main body of the distribution member constitutes a porous body portion (16) being surrounded by a second gas (2). If a pressure gradient is created between the second gas (2) and the first gas (1), i.e. the first gas (1) being at a slightly lower pressure, the second gas (2) will leak trough the porous body (16) and thereby preventing powder, in the mix of the first gas and fine powder, from sticking or clogging within the distribution member, which thereby forms an active non-sticking wall relative to of the fine powder.

  • Patent number: 6671161
    Abstract: A method and a device for quick neutralization of a created electrostatic field formed by a multitude of basically charged particles includes a medication powder (180) deposited onto a defined target area (160) of a substrate member (140) in the course of a dose forming process. A charge generator emits charges, which are directed towards the target area of the substrate member such that the electric field created by the accumulated charges from the deposited particles is neutralized by the added charges. Various elements may be used to generate neutralizing charges, but an ion source (195) is most efficient in achieving neutralization of the dose charge and the substrate. The source may be applied so that the dose (180) and the target area (160) are exposed to the emitted charges during the entire or part of the dose forming process.

  • Publication number: 20030200967
    Abstract: A method and a device involving an electric iris diaphragm/shutter are disclosed for controlling particle transfer of electrically charged medication powder particles from a source to a defined target area, of a substrate. Spatial distribution of particles onto the target area is achieved by an electro-dynamic field technique (320) applied to the distribution and deposition of particles in a dose forming process. An electric iris diaphragm/shutter (130) is located between a particle generator (110) and the substrate (140) such that all particles must pass the iris diaphragm for being transferred to the substrate. By adjusting amplitude and frequency of a superimposed AC potential (136) charged particles will oscillate in the created AC field such that only small light particles will emerge from the iris diaphragm/shutter for further transfer in the dose forming process.

  • Patent number: 6622723
    Abstract: A dosing device of an inhaler for administration of a pharmaceutical composition during a prolonged time period is disclosed. The principle of the inspiratory administration is basically utilizing known techniques for administering of the pharmaceutical composition, whereby the fine powder to be administered is gathered as extended doses (15, 16) of powder onto a surface of a dosing member. The disposable dosing member (10) contains a number of prefabricated dose strings to be accessed. A dosing element (7) having an adapted opening moves along an extended string of the dosing member during the administration to in this manner prolong the time period, during which the pharmaceutical composition is released from the dosing member (10) into an air-stream of the inhaler during the inspiration. The relative motion of the dosing element (7) is either obtained by rotating the dosing member itself or moving the dosing element along the surface of the dosing member.

  • Patent number: 6571793
    Abstract: A method and a process are disclosed for optimizing an electrostatically dosed dry powder inhaler (EDPI) for utilization of a prepared pre-metered electro-dose consisting of a electro-powder. An arrangement is set-up for measuring parameters affecting a systemic delivery or local lung delivery of a pre-metered electro-dose from and DPI including analysis of dose de-agglomeration, particle size distribution as well as dose-to-dose variation together with pressures times and flows. A dry powder inhaler, DPI, is adjusted for a systemic or a local lung setting with respect to activation pressure and closing pressure having a DPI with a 20 to 60 liters/minute inhalation air flow for systemic delivery setting and 20 to 80 liters/minute for a local lung setting. Furthermore the de-agglomeration power is adjusted between 0.1 and 6 watts to be used in the DPI by optimizing the pressure drop and inhalation flow rate by changes to the mouthpiece and/or the device member and their relation to each other.

  • Patent number: 6526969
    Abstract: An inhaler device and a method in which powder for inhalation is jetted off a prepared device surface containing a defined pre-metered quantity of finely divided powder. The jetting function is obtained by a directed air stream pushing or cutting free a medical powder applied to a carrier surface and by creating a stream of air dispersing the powder into inspiratory air at the moment it is being inhaled. The inhaler device includes active (air permeable) porous walls for preventing finely divided powder from sticking to the inner faces of the inhaler device by creating a pressure gradient across the active wall, thus forcing a small flow of air through the active wall thereby keeping the powder from sticking to the inner faces.
