Multidose inhaler

The present invention relates to an inhaler which comprises a durable unit and a replaceable (cartridge) unit, and which comprises systems, subsystems and elements to provide an “open-inhale-close” user experience. A durable unit comprises a breath-actuated trigger mechanism, and optionally electronics for providing user feedback, and telehealth can capability. A replaceable unit comprises a mouthpiece, blister strip, aerosol path dose counter and a blister piercing and aerosolization engine assembly assembly. A lockout mechanism may be provided to prevent further use of the cartridge when the dose counter reaches a preselected limit, such as zero.

Respiratory device tracking system

An inhaler tracker module is secured to an inhaler and has an activation sensor for sensing use of the inhaler. The tracker module includes a memory for storing inhaler use data, and a communications component for wirelessly transmitting the stored inhaler use data. The tracker module is wrapped around the inhaler body and includes a pressure switch located at the top of the canister to detect a user pressing the canister into the body for inhaler use. The tracking module has a standby mode in which it remains until inhaler use or until inhaler use data is stored and it is transmitted. A pairing function is provided.

DRY POWDER INHALER

A dry powder inhaler (10) having a chamber (26) divided into first and second blister compartments (28, 30) for storing unused and used portions (34, 36) of a blister strip (12) is provided. A moveable dividing wall (32) separates the first and second blister compartments. One or more arcuate supporting surfaces (38, 40, 42) are disposed in either the first and/or the second blister compartments and these surfaces support the used or unused blister strip during successive actuations of the inhaler. Use of the arcuate supporting surfaces facilities compact coils of unused and used portions of blister strip, thereby reducing the size of the chamber required for the inhaler.

Dry powder inhaler dose counters

Dry powder inhaler dose counters capable of making a display move swiftly between digits. In contrast to the progressive movement that occurs in simple gearing mechanisms, there is provided a dry powder inhalation device comprising a housing defining a chamber, a patient port in communication with said chamber, an elongate carrier carrying medicament, an advancement mechanism for advancing a length of the elongate carrier into the chamber, a displacement sensor that advances in association with continuous advancement of the elongate carrier, and a transfer component that converts the advancement of the displacement sensor into intermittent motion of a units dose display.

Powder filling processes

A method for filling a plurality of microdepressions in a major surface of a web with finely divided powder in which the web is fed continuously to and through a powder filling stage including a driven roller. A method of manufacturing an elongate carrier with microdepressions containing finely divided powder comprising steps filling a plurality of microdepressions in a major surface of a web as described, removing from upper surface of the web excess powder not filled within the microdepressions and remaining on areas of the surface between the depressions, and optionally slitting and/or cutting the web in width and/or length.

20210069106 · 2021-03-11 ·

The present invention comprises methods and formulations to increase drug payload, especially in regard to a receptacle-based, inhalation dosed, dry powder therapeutic, wherein the methods and formulations are characterized by a high product density, as well as a high TLD per receptacle, while maintaining highly efficient aerosol performance from the device. Embodiments of the present invention comprise a spray-dried pharmaceutical powder comprising particles deliverable from a dry powder inhaler, the composition comprising active agent, and a shell-forming excipient, wherein the powder is characterized by a product density greater than 50 mg/ml.

MEDICAMENT DISPENSER
20210085897 · 2021-03-25 · ·

A medicament dispenser for dispensing medicament comprising: an assembly comprising: at least one peelable medicament carrier carrying multiple distinct medicament portions; a medicament carrier advancing mechanism; a flow channel; and a hinged cover for the flow channel.

PRE-EMPTIVE ASTHMA RISK NOTIFICATIONS BASED ON MEDICAMENT DEVICE MONITORING

This description provides risk notifications for a geographic region to inform patients and effect behavior changes to prevent rescue events and exacerbations from occurring. A risk analysis for a geographic region is based on data gathered from a population of patients who may experience respiratory events within the geographic region. Rescue medication events, environmental conditions relevant to the rescue medication events, and other contextually relevant information are detected by sensors associated with a population of patients' medicament device/s and are collected from other sources, respectively, to provide a basis to determine a risk score. This data is analyzed to determine the severity of the risk of a respiratory event occurring within a geographical region and accordingly sending a notification to patients within that geographical region.

Heat Units Using a Solid Fuel Capable of Undergoing an Exothermic Metal Oxidation-Reduction Reaction Propagated without an Igniter
20210008300 · 2021-01-14 ·

A heating unit comprising an electrically conductive substrate. A solid fuel layer comprising a metal reducing agent, a metal containing oxidizing agent and a binder is coated on a surface of the substrate, the solid fuel layer having a solid fuel surface spaced from the substrate. A first electrode coupled to the substrate. A second electrode coupled to the solid fuel surface. A power supply is configured to be selectively coupled to the first and second electrodes to provide a voltage between the metallic substrate and the solid fuel surface. The voltage acts to propagate an exothermic metal oxidation-reduction reaction without the use of an igniter.
