Dry Powder Inhaler

View page
US Patent:
6715486, Apr 6, 2004
Filed:
Jan 31, 2001
Appl. No.:
09/773261
Inventors:
Andrew W. Gieschen - San Diego CA
Michael Ligotke - San Diego CA
Jeffrey Chen - San Diego CA
Charles Ganem - San Diego CA
Bernard Greenspan - San Diego CA
Assignee:
Quadrant Technologies Limited - Nottingham
International Classification:
A61M 1600
US Classification:
12820315, 12820312, 604 58
Abstract:
A dry powder inhaler has a dispersion chamber containing beads. A dose of dry powder is released into the chamber, or into an inlet tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece, air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from the larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater air flow and powder dispersion, without any increased effort by the patient.

6971384, Dec 6, 2005
Filed:
Feb 19, 2004

International Classification:

US Patent:
7069929, Jul 4, 2006
Filed:
Mar 15, 2002
Appl. No.:
10/099592
Inventors:
Matthew Young - Hertfordshire, GB
Stuart Kay - Hertfordshire, GB
Neil Harrison - Hertfordshire, GB
James Welsh - Tyne and Wear, GB
Michael Ligotke - San Diego CA, US
Assignee:
Quadrant Technologies Limited
International Classification:
A61M 15/00
B65D 83/06
US Classification:
12820315, 12820321, 12820312, 604 58
Abstract:
A dry powder inhaler includes an actuator pivotably mounted on a base. Movement of the actuator from a first position to a second position drives the a dobber to open a blister. A dispersion engine sub-assembly has a blister hood positioned over a blister opening position. A powder pathway connects from the blister hood into a powder dispersion engine. Upon inhalation, air flow draws powder up and out of an opened blister, into the blister hood and to the powder dispersion engine. Movement of the actuator causes the dobber to shear open a blister and also to press the blister hood down over the blister. This increases air flows up and around the open blister, carrying the pharmaceutical powder up and out of the blister and into the dispersion engine.

US Patent:
7556035, Jul 7, 2009
Filed:
May 17, 2005
Appl. No.:
11/130970
Inventors:
Matthew E. Young - Cambridge, GB
Stuart Brian William Kay - Cambridge, GB
Neil Richard Harrison - Birmingham, GB
Michael W. Ligotke - San Diego CA, US
Assignee:
Quadrant Technologies Limited - Ruddington, Nottingham
International Classification:
A61M 15/00
US Classification:
12820315, 12820312, 12820323
Abstract:
A unit dose dry powder inhaler includes a chamber housing containing a powder dispersion chamber. A chamber tube extends from the dispersion chamber into the mouthpiece. A cover or cup is rotatably attached to the chamber housing. A dose of a dry powder is contained at a powder location in the chamber housing. An air passageway leading from the powder location to the dispersion chamber is closed off by the cover. When the cover is rotated to an open position, the air passageway is opened. The user inhales on the mouthpiece drawing air through the powder location, the air passageway, the dispersion chamber and the chamber tube, through the mouthpiece and into the users lungs. The unit dose of dry powder is stored directly in, or is part of, the inhaler.

US Patent:
20050263153, Dec 1, 2005
Filed:
May 17, 2005
Appl. No.:
11/130959
Inventors:
Matthew Young - Cambridge, GB
Stuart Brian Kay - Cambridge, GB
Neil Harrison - Birmingham, GB
Michael Ligotke - San Diego CA, US
International Classification:
B05D007/14
A61M015/00
US Classification:
128203150, 128203210
Abstract:
A unit dose dry powder inhaler has a dose unit within an inhaler housing. As the dose unit is pushed into the inhaler housing, a container on the dose unit is opened, releasing a pharmaceutical powder into the housing. The user inhales on a mouthpiece, drawing the powder and air into a dispersion chamber. The powder disperses in air, and the powder/air mixture is inhaled. The inhaler is inexpensive, compact, and simple to use.
