DRUG DOSE CARTRIDGE FOR AN INHALER DEVICE
First Claim
Patent Images
1. A dose cartridge for an inhaler device, the dose cartridge comprising:
- a flat pallet of airflow-permeable material including a heat-vaporizing drug substance, the pallet having two opposing faces and being positioned in the dose cartridge so as to expose the two faces to airflow;
a supporting member coupled to the pallet to support the pallet from at least one side of the pallet joining the two faces; and
an electrically resistive heating element extending at least partially across at least one of the two opposing faces from an attachment with the supporting member;
wherein the resistive heating element is in thermal contact with and extends across at least two opposite surfaces of the pallet and comprises a U-shape with two ends around a hollow in which the pallet is positioned.

Abstract
Devices and methods are described for preparing, managing, and/or administering metered doses of substances for vaporized administration. In some embodiments, dose cartridges comprising at least one botanical substance include a heating element integrated into the cartridge in close contact with the botanical substance. In some embodiments, cartridge-mounted doses are stored in a magazine, optionally in carousel form, before use. Transport of a cartridge from a magazine to an electrically operated vaporizing chamber which activates the heating element is provided by a mechanical pickup means.

51. A dose cartridge for an inhaler device, the dose cartridge comprising:
-
a flat pallet of airflow-permeable material including a heat-vaporizing drug substance, the pallet having two opposing faces and being positioned in the dose cartridge so as to expose the two faces to airflow; a supporting member coupled to the pallet to support the pallet from at least one side of the pallet joining the two faces; and an electrically resistive heating element extending at least partially across at least one of the two opposing faces from an attachment with the supporting member; wherein a portion of the resistive heating element extending across the pallet comprises a barrier which prevents a granulate portion of the pallet from leaving the inhaler dose cartridge. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59)
