Abstract

The present application provides a priming member for an inhaler and a method of loading an inhaler with a carrier for treating a respiratory disease by inhaling a powder from the inhaler. The priming member comprises a cantilever blade configured to engage a chassis of the inhaler, the cantilever blade having a proximal portion, a body and a distal portion, the body being disposed between the proximal portion and the distal portion of the cantilever blade and the cantilever blade having a flexible portion extending with the proximal portion of the cantilever blade to allow movement of the cantilever blade relative to the chassis.

First claim

1 . A priming member for an inhaler, the priming member comprising a cantilever blade configured to engage a chassis of the inhaler, the cantilever blade having a proximal portion, a body and a distal portion, the body being disposed between the proximal portion and the distal portion of the cantilever blade and the cantilever blade having a flexible portion extending with the proximal portion of the cantilever blade to allow movement of the cantilever blade relative to the chassis.

2 . The priming member of claim 1 , wherein the flexible portion is a hinge flexure allowing the cantilever blade to move in an upward and downward direction relative to the chassis of the inhaler.

3 . The priming member of claim 2 , wherein the cantilever blade is adapted to pass over a shelf of the chassis upon actuation of the inhaler and under the shelf of the chassis upon indexing of the inhaler.

4 . The priming member of claim 1 , wherein the body of the cantilever blade comprises a longitudinal axis extending from the proximal portion to the distal portion of the cantilever blade, and the flexible portion extends transverse to the longitudinal axis.

5 . The priming member of claim 2 , wherein the cantilever blade comprises a first surface and a second surface extending along the longitudinal axis of the cantilever blade, the first surface opposite the second surface such that a first gap is formed between the priming member and the first surface of the cantilever blade and a second gap is formed between the second surface and the priming member.

6 . The priming member of claim 1 , wherein the distal portion of the cantilever blade comprises an angled tip.

7 . The priming member of claim 1 , wherein the cantilever blade has a wedge shape or a rectangular shape.

8 . The priming member of claim 6 , wherein the tip of the cantilever blade is chamfered.

9 . An inhaler for inhaling a dose of powder, the inhaler comprising a mouthpiece for inhaling the dose of powder; and a priming member fluidly coupled to the mouthpiece, the priming member comprising a cantilever blade configured to engage a chassis of the inhaler, the cantilever blade having a proximal portion, a body and a distal portion, the body being disposed between the proximal portion and the distal portion of the cantilever blade and the cantilever blade having a flexible portion extending with the proximal portion of the cantilever blade to allow movement of the cantilever blade relative to the chassis.

10 . The inhaler of claim 9 , wherein the flexible portion is a hinge flexure allowing the cantilever blade to move in an upward and downward direction relative to the chassis of the inhaler.

11 . The inhaler of claim 9 , wherein the cantilever blade is adapted to pass over a shelf of the chassis upon actuation of the inhaler and under the shelf of the chassis upon indexing of the inhaler.

12 . The inhaler of claim 9 , wherein the body of the cantilever blade comprises a longitudinal axis extending from the proximal portion to the distal portion of the cantilever blade, and the flexible portion extends transverse to the longitudinal axis.

13 . The inhaler of claim 12 , wherein the cantilever blade comprises a first surface and a second surface extending along the longitudinal axis of the cantilever blade, the first surface opposite the second surface such that a first gap is formed between the priming member and the first surface of the cantilever blade and a second gap is formed between the second surface and the priming member.

14 . The inhaler of claim 9 , wherein the distal portion of the cantilever blade comprises an angled tip.

15 . The inhaler of claim 9 , wherein the cantilever blade has a wedge shape or rectangular shape.

16 . The inhaler of claim 14 , wherein the tip of the cantilever blade is chamfered.

17 . A chassis for an inhaler, the chassis comprising a plate having guide members disposed adjacent a first aperture, a pivot shaft configured for supporting a priming member, a peripheral casing configured for rotatably supporting a pocket having a medicament, a clip having a second aperture for receiving a wheel rotatably mounted on the chassis on an axis offset from a central axis, and a shelf disposed adjacent the second aperture, the shelf defining a third aperture, the third aperture configured for receiving a cantilever blade of the priming member of the inhaler.

18 . The chassis of claim 17 further comprising a plurality of radially located ribs on the chassis and a plurality of peripherally located buttresses on the chassis configured for stabilizing the chassis and the priming member of the inhaler.

19 . The chassis of claim 17 , wherein the third aperture is enclosed by a wall at one end and by an edge support at the other end.

20 . The chassis of claim 19 , further comprising a lower step and a higher step, the steps peripherally positioned on the chassis to allow molding.
