Abstract
The present invention relates to a metered dose inhaler (MDI) device comprising a mechanically activated visual cue representing a number of doses expelled from, or doses remaining in, a drug-containing cartridge or canister locatable within a body of said MDI, wherein the visual cue is visible through at least a portion of the body of said MDI, and a removable data processing system configured to verify the dose of drug administered and/or inhaled, wherein the MDI device further comprises a correlation system configured to correlate physically released doses from the drug containing cartridge or canister with the administration and/or inhalation data stored in the removable data processing system.
Core Innovation
A handheld metered dose inhaler (MDI) is provided with a mechanically activated visual cue that represents a number of doses expelled from, or doses remaining in, a drug-containing cartridge or canister locatable within a body of the MDI. The visual cue is visible through at least a portion of the body of the MDI, and is mechanically linked to drug-cartridge depression so that the cue changes as physically released doses occur.
A removable data processing system is configured to verify the dose of drug administered and/or inhaled. A correlation system correlates physically released doses from the drug containing cartridge or canister with administration and/or inhalation data stored in the removable data processing system.
The correlation system includes mechanical activation means in contact with a drug containing cartridge and translational movement conversion means that convert translational movement of the mechanical activation means into a rotational movement. At least a first rotational position sensor and at least a second rotational position sensor convert an angle of rotation into electrical signals, and the rotational position sensors are connected via a reducing gear.
Claims Coverage
The provided content includes one independent claim with three main inventive features: a mechanically activated visible dose-counting cue; a removable data processing system for verifying administered and/or inhaled dose; and a correlation system that links cartridge dosing to stored administration and/or inhalation data via translational-to-rotational conversion and rotational position sensing.
Mechanically activated visible dose-counting cue for expelled or remaining doses
A metered dose inhaler device comprising a mechanically activated visual cue representing a number of doses expelled from, or doses remaining in, a drug-containing cartridge or canister, wherein the visual cue is visible through at least a portion of the body of the MDI.
Removable data processing system for verifying administered and/or inhaled dose
A removable data processing system configured to verify the dose of drug administered and/or inhaled.
Correlation of physically released doses with stored administration and/or inhalation data
A correlation system configured to correlate physically released doses from the drug containing cartridge or canister with administration and/or inhalation data stored in the removable data processing system.
Translational to rotational conversion driven by mechanical activation means
The correlation system comprises mechanical activation means in contact with a drug containing cartridge and translational movement conversion means configured to convert a translational movement of the mechanical activation means into a rotational movement.
Rotational position sensing with reducing gear producing electrical signals
The correlation system further comprises at least a first rotational position sensor and at least a second rotational position sensor connected via a reducing gear, wherein the rotational position sensors are configured to convert an angle of rotation into an electrical signal.
Overall, the claim coverage centers on a mechanically activated, through-body visible dose cue paired with a removable verification system, and a correlation architecture that converts cartridge-driven translational motion into rotational motion for rotational position sensors that output electrical signals.
Stated Advantages
Verifies the dose of drug administered and/or inhaled.
Correlates physically released doses from the drug containing cartridge or canister with administration and/or inhalation data stored in the removable data processing system.
