Publication number: 20020170920Abstract: A device for dispensing metered dosages of a substance from a container includes a dispenser housing and an indicating device. The indicating device includes an indicator housing, at least one engagement member disposed in the indicator housing, a plurality of indicator members coaxially mounted in the indicator housing, and an actuator coupled to and moveable with the container relative to the plurality of indicator members and the dispenser housing. The actuator member is selectively engaged with at least one of indicator members and is operative to advance the at least one indicator member an incremental amount. The at least one engagement member is selectively engaged with an advancement member so as to bias the advancement member into operable engagement with at least one of the indicator members and move the at least one indicator member an incremental amount. A method for dispensing metered dosages of the substance is also provided.Type: ApplicationFiled: July 11, 2002Publication date: November 21, 2002Inventors: Richard Blacker, Daniel K. Engelbreth, James N. Schmidt

Publication number: 20020170928Abstract: An actuator is used to dispense a medicament from a container having at least a first and second portion. The actuator includes a holder, a trigger member and a push member. The holder is adapted to engage at least the first portion of the container. The trigger member is pivotally connected to the holder at a pivot axis, wherein the trigger member is pivotable about the pivot axis in a first direction toward the grippable portion and a second direction opposite the first direction. The push member is connected to the trigger member, wherein the push member is pivotable about the pivot axis in the first direction as the trigger member is pivoted in the first direction and wherein the push member is pivotable about the pivot axis in the second direction as the trigger member is pivoted in the second direction. The push member is adapted to move at least the second portion of the container relative to the holder as the push member is pivoted in the first direction.Type: ApplicationFiled: April 12, 2002Publication date: November 21, 2002Inventors: Jerry Grychowski, Martin P.

Patent number: 6435372Abstract: An indicating device for use with a dispensing device that dispenses metered dosages of a medicament from a container having a valve moveable between an open and closed position. In a preferred embodiment, the container is reciprocally moveable within the housing along a longitudinal axis. The housing preferably has a well adapted to receive a valve stem and an exhaust port. The well communicates with the port such that the metered dosage of medicament is dispensed through the port when the valve is moved to the open position. An indicator assembly comprises an indicator member that includes dosage indicia visible to a user. In a preferred embodiment, the indicator assembly is provided in an indicator module. A method for dispensing measured dosages is also provided, along with a kit capable of being assembled as an inhalation device. A delivery system having a key member and a key entry passageway is also provided.Type: GrantFiled: September 14, 2001Date of Patent: August 20, 2002Assignee: 1263152 Ontario Inc.Inventors: Richard Blacker, Daniel K.

Patent number: 6435177Abstract: The invention provides an aerosol medication delivery apparatus for use with a pMDI canister having medication and a propellant contained therein under pressure, wherein the pMDI canister has a discharge orifice from which the medication and propellant can be discharged forming an aerosol. The apparatus has a chamber housing having an input end and an output end and defining an interior space, wherein the input end receives the medication discharged from the discharge orifice of the pMDI canister into the interior space and wherein the medication can be withdrawn from the interior space by inhalation by a patient from the output end. The aerosol medication delivery apparatus also includes a valve at the output end. The valve has a valve seat and a valve member. The valve seat has a sealing surface and the valve member has a central open area and a sealing portion at the perimeter of the open area that mates with the sealing surface when the valve is closed.Type: GrantFiled: August 15, 2001Date of Patent: August 20, 2002Assignee: Trudell Medical InternationalInventors: James N. Schmidt, Jerry Grychowski, Daniel K. Engelbreth, Robert Morton, Martin P. Foley

Patent number: 6142339Abstract: An aerosol dispenser for dispensing metered dosages of medicaments from a container having a valve stem extending longitudinally therefrom and moveable between an open and closed position. The container is reciprocally moveable within the housing along a longitudinal axis. The housing has a well adapted to receive the valve stem and an exhaust port. The well communicates with the port such that the metered dosage of medicament is dispensed through the port when the valve stem is moved to the open position. A worm is rotatably mounted in the housing about an axis transverse to the longitudinal axis and is responsive to the movement of the reciprocal movement of the container within the housing such that the longitudinal movement causes the worm to rotate about its axis. An indicator member includes dosage indicia visible to a user and a circular gear mounted in the housing about an axis transverse to the axis of the worm and to the longitudinal axis. The circular gear engages the worm.Type: GrantFiled: January 16, 1998Date of Patent: November 7, 2000Assignee: 1263152 Ontario Inc.Inventors: Richard Blacker, Daniel K. Engelbreth, James N. Schmidt
