Patent CA-2433799-A1 (CA)
Title: Dry powder inhaler
Inventor: GENOVA PERRY
IPC: B05B17/06
Filed: 2001-12-18
Abstract: A dry powder inhaler having a housing, at least one single dose storage chamber (17) able to contain a single unit dose, a discharge path (20) adjacent the storage chamber (17), and a flexible and bendable seal plate (14) closing the discharge path (20). When an air flow under pressure is applied to the top of the dose, the top seal is broken and the dose is driven against the seal plate (14) which deflects away, allowing the powder of the dose to be driven into and along the discharge path (20). The air flow causes the seal plate (14) (in the discharge path) to vibrate, which acts to break up the dose into particles of preferred size, as the dose is carried along with the air flow and delivered to a patient.

Abstract: The present invention provides a railing system that is modular and can be interconnected in an easy manner. The railing system comprises a top elongated member having a downwardly opening channel and a bottom elongated member having an upwardly opening channel. A number of spaced apart vertical members span the distance between the top and bottom members, wherein one end of a vertical member is inserted into the channel in the top member and the opposite end is inserted into the channel provided in the bottom member. The orientation and position of the top and bottom members is provided by the interconnection of these elongated members to supports, or posts. Due to the spaced apart relation of the vertical members positioned in the channels, portions of the top and bottom channels are exposed. These exposed portions between the vertical members are enclosed by top and bottom spacers, which interconnect with the top and bottom members, respectively. A particular spacer is secured in a location within the cross section of the top member or the bottom member by one or more interconnection mechanisms. The interconnection mechanisms associated with the edges of the spacers, mate with interconnection mechanisms provided along the length of the top and bottom members that are located on the interior of a channel at the open face thereof. By providing interconnection mechanisms within the interior of a channel, the spacers may be more effectively secured to the top and bottom members thereby potentially limiting their accidental removal. In addition this method of interconnection within the cross section of a top or bottom member may enhance the structural integrity of the top and bottom members as well as possibly improve the aesthetics thereof.
