Patent number: 6881398Abstract: A therapeutic dry powder preparation and a method of administering such a preparation are disclosed for effectively de-aggregating and dispersing into air a dose of medication powder in an administration the dose to a user. The present dry powder preparation and method do not require other sources of energy besides the power of an inhalation effort by a user to produce a very high degree of de-aggregation and efficient dispersal into air of the dry powder medication dose. Utilizing an effort of sucking air through a nozzle, the particles of the therapeutic powder dose, made available to the nozzle, are gradually de-aggregated and dispersed into a stream of air entering the nozzle.Type: GrantFiled: April 30, 2002Date of Patent: April 19, 2005Assignee: Microdrug AGInventors: Mattias Myrman, Per-Gunnar Nilsson

Patent number: 6722365Abstract: 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.Type: GrantFiled: January 7, 2003Date of Patent: April 20, 2004Assignee: Microdrug AGInventors: Thomas Nilsson, Lars-Gunnar Nilsson

Patent number: 6676162Abstract: An inflatable belt presenter for use with an occupant restraint belt of a motor vehicle has a stored condition wherein the presenter is deflated and allows the restraint belt to assume a stowed position, and a deployed condition wherein the presenter is inflated and urges the belt to a graspable position in which the occupant can more easily grasp the belt prior to fastening it. The presenter is inflated by a source of gas pressure carried on board the vehicle, such as a compressor, pressure vessel, or a seat-mounted bladder after an occupant has been seated in the seat and is ready to don the restraint belt. Inflation of the presenter preferably occurs upon activation by an electronic control system that receives inputs from one or more vehicle systems, such as a seat weight sensor, a door open/closed sensor, and/or an ignition switch. The inflated presenter is flexible and compliant enough that it will not cause any discomfort to the seat occupant if it should contact the occupant's body.Type: GrantFiled: April 24, 2002Date of Patent: January 13, 2004Assignee: Ford Global Technologies, LLCInventors: Per Gyllenspetz, Bjorn Lundell, Gunnar Nilsson, Henrik Wiberg, Per Ferdell

Patent number: 6622723Abstract: 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.Type: GrantFiled: November 2, 2000Date of Patent: September 23, 2003Assignee: Microdrug AGInventors: Thomas Nilsson, Lars-Gunnar Nilsson

Patent number: 6616028Abstract: A locking device in a stapler adapted to lock a displaceable member carrying a catch for an object to be stapled in an optional position along a bar. The bar extends through a hole in a locking element. The locking element is connected to the displaceable member and is tiltable along the bar from a pinch position in which the locking element is pinched to the bar to a free position in which the locking element is free from the bar. The locking element is spring-biased towards its pinch position. An operating handle mounted on the displaceable member and operable outside the stapler is displaceable to a limited extent relative to the displaceable member. Exerting a forward force on the handle moves the displaceable member forward.Type: GrantFiled: July 3, 2001Date of Patent: September 9, 2003Assignee: Isaberg Rapid ABInventor: Gunnar Nilsson

Patent number: 6575161Abstract: The invention discloses a method and a device for classification and, if required, electrostatic charging of a resulting separated decomposed powder preferably in the form of a substance intended for inhalation purposes. The classification takes place in that the powder is released from a device decomposing the suitable substance, whereby the powder is given a velocity perpendicular to in applied electric field (8). By adapting the strength of the electric field decomposed powder, i.e. individual particles resembling dust, will by means of the electric field (8) be attracted to a device (9) from which dosing of the individual particles then takes place. Larger particles (agglomerates) then will proceed straight ahead in an initial velocity direction as their kinetic energy is essentially larger than that for the small particles.Type: GrantFiled: January 29, 2001Date of Patent: June 10, 2003Assignee: Microdrug AGInventor: Lars-Gunnar Nilsson

Patent number: 6550805Abstract: An occupant restraint belt for use with a seat of a motor vehicle has an inflatable section having a deflated condition wherein the belt assumes a stowed position and an inflated condition wherein the belt assumes a deployed position in which the belt is in a position making it easy for a seat occupant to see and grasp the belt in order to fasten it. The inflatable section is formed by sewing a layer of flexible material to the webbing that constitutes the main restraint member of the belt to form at least one gas-tight inflation chamber. The belt is inflated after an occupant is seated in the seat and ready to don the restraint belt. Inflation of the inflatable section preferably occurs upon activation by an electronic control system that receives inputs from one or more vehicle systems, such as a seat weight sensor, a door open/closed sensor, and/or an ignition switch.Type: GrantFiled: February 1, 2002Date of Patent: April 22, 2003Assignee: Ford Global Technologies, LLCInventors: Per Gyllenspetz, Bjorn Lundell, Gunnar Nilsson, Henrik Wiberg, Per Ferdell

Patent number: 6526969Abstract: 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.Type: GrantFiled: June 7, 2001Date of Patent: March 4, 2003Assignee: Microdrug AGInventors: Lars-Gunnar Nilsson, Thomas Nilsson
