Abstract

Provided is a blister pack for a dry powder inhaler, which dry powder inhaler is configured to deliver a first powder medicament and a second powder medicament different from the first powder medicament. The first and second powder medicaments are contained within blister pockets defined in a strip. A series of blister pockets is defined in the strip, which series extends linearly along the length of the strip. The first and second powder medicaments are contained in blister pockets, e.g. respective blister pockets, of the series. Alternatively or additionally, each of the blister pockets is elongated such as to have a largest dimension parallel with the length of the strip. These measures, either individually or in combination, enable minimizing of the width of the strip in spite of the strip accommodating both the first and second powder medicaments. This, in turn, may enable the depth/thickness of the dry powder inhaler to be minimized, and/or additional space to be provided inside the dry powder inhaler for accommodating, for example, use detection and wireless connectivity electronics for sending use detection data to an external device, such as a smartphone.

1 .- 52 . (canceled)

53 . A dry powder inhaler configured to deliver a first powder medicament and a second powder medicament different from the first powder medicament, the dry powder inhaler comprising:
a blister pack; and a medicament delivery assembly, wherein the blister pack comprises: a strip having blister pockets, said first and second powder medicaments being contained within the blister pockets, wherein a series of blister pockets is defined in the strip, the series extending linearly along a length of the strip, wherein each of the blister pockets is divided into a first pocket portion containing the first powder medicament, and a second pocket portion containing the second powder medicament, the first pocket portion adjoining the second pocket portion at a pinch point for restricting combining of the first and second powder medicaments with each other, wherein the blister pack further comprises a peelable cover for covering the blister pockets, wherein the blister pockets are defined in a base layer, and wherein the peelable cover is releasably adhered to the base layer between the blister pockets, and
wherein the medicament delivery assembly is configured to:
access the blister pockets and permit a subject to inhale the first and second powder medicaments therefrom,
wherein the medicament delivery assembly is configured to permit the subject to inhale the first and second powder medicaments simultaneously, the medicament delivery assembly being configured to access the first and second pocket portions for each inhalation using the inhaler,
wherein the medicament delivery assembly comprises a peeling mechanism configured to peel the cover covering the first and second pocket portions to expose the first and second powder medicaments for each inhalation using the inhaler,
wherein the pinch point is configured to provide communication between the first and second pocket portions of each blister pocket.

54 . The dry powder inhaler according to claim 53 , further comprising a mouthpiece, wherein the medicament delivery assembly comprises a manifold configured such that the first and second powder medicaments from the accessed first and second pocket portions are drawn simultaneously therethrough and out of the mouthpiece when the subject inhales through the mouthpiece.

55 . The dry powder inhaler according to claim 54 , wherein the manifold comprises a first flow path along which the first powder medicament is carried towards the mouthpiece from one of the pocket portions, and a second flow path along which the second powder medicament is carried towards the mouthpiece from the other of the pocket portions.

56 . The dry powder inhaler according to claim 55 , wherein the first and second flow paths meet with each other at a point upstream of the mouthpiece.

57 . The dry powder inhaler according to claim 53 , wherein each of the blister pockets is elongated such that each blister pocket has a largest dimension that is parallel to the length of the strip.

58 . The dry powder inhaler according to claim 53 , wherein the communication between the first and second pocket portions is provided adjacent to the peelable cover.

59 . The dry powder inhaler according to claim 53 , wherein the first pocket portion is at a different position along the length of the strip than the second pocket portion.

60 . The dry powder inhaler according to claim 53 , wherein the first pocket portion contains a different volume of the first powder medicament than the second powder medicament contained by the second pocket portion.
