US Patent:

20050016527, Jan 27, 2005

Filed:

Dec 17, 2002

Appl. No.:

10/499309

Inventors:

Lee Barger - Durham NC, US
David Moody - Durham NC, US
Robert Schultz - Durham NC, US
Jonathan Spencer - Durham NC, US

International Classification:

A61M011/00

US Classification:

128200230

Abstract:

A testing apparatus and method for characterizing the aerodynamic particle size of an atomized medicament emitted from a metered dose inhaler unit during testing with a particle characterization device in which the testing apparatus includes a first clamp of a first fixture in removable clamping and locking engagement with a throat, which is in fluid communication with a particle characterization device, a second clamp in removable clamping and locking engagement with a delivery device of the metered dose inhaler unit having a canister, containing atomized medicament, operatively loaded therein, an alignment mechanism that removably couples the first fixture to the second fixture at an aligned position therefore causing the throat to be in fluid communication with the delivery device, and an actuation assembly mounted to the first fixture having means that operatively thrusts the canister into the delivery device of the metered dose inhaler unit, thus releasing atomized medicament.

Robert David Schultz - Durham NC, US

International Classification:

A61M 15/00

US Classification:

12820023

Abstract:

Metering valves for use in a metered dose inhaler that include a valve body, a first stem seal including a first elastomeric material, a second stem seal including a second elastomeric material different from the first elastomeric material, and a valve stem slidably engaged with at least one of the first stem seal and the second stem seal as well as sealed containers configured to contain an aerosol pharmaceutical formulation that include a container having an opening therein, a cap covering the opening in the container, a metering valve adjacent the cap, and a cap seal positioned between the cap and the container to provide a sealed container where the metering valve include at least one stem seal that includes a first elastomeric material, and the cap seal includes a second elastomeric material different from the first elastomeric material are described.
