US 12,109,357 B2 · Blister pack and inhaler comprising the same

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.
