A system may include an external device and an inhaler. The external device may include a processor, a communication circuit, and memory. The inhaler may include a mouthpiece, medicament, a mechanical dose counter, and an electronics module comprising a processor and a communication circuit. The electronics module may record a dosing event when the inhaler is actuated, such as when the mouthpiece cover is opened, and send a signal indicating the dosing event to the external device. The external device may receive a mechanical dose reading of the mechanical dose counter, determine an electronic dose reading based on the signal indicating the dosing event, determine that a discrepancy between the mechanical dose reading and the electronic dose reading exceeds a threshold, and notify the user of the discrepancy, for example, by providing a notification to the user by way of a mobile application residing on the external device.

Some embodiments are directed to an adherence monitor for use with a tethered cap inhaler device. The adherence monitor engages the inhaler device, and includes a tether opening located within a housing of the adherence monitor for receiving the tether. The tether opening is in the form of a slot in a base portion of the housing. The path length of the tether around the adherence monitor is kept from being increased, compared to its path length when the adherence monitor is not attached to the inhaler, by having the slot located to allow the tether to pass through the slot. Various sensors of the adherence monitor in various embodiments detect inhaler usage.

The manifold component comprises: a primary air inlet opening for receiving first external air; an air outlet opening for providing the external air from the primary air inlet opening into an opened blister pocket, the primary air inlet opening being fluidly connected to the air outlet opening by a primary air delivery conduit formed in the manifold component; a medicament inlet opening for receiving air-entrained medicament from the opened blister pocket, the air outlet opening and the medicament inlet opening being arranged side-by-side to enable simultaneous communication with the opened blister pocket; and a medicament outlet opening for delivery of the air-entrained medicament from the opened blister pocket to the user, the medicament inlet opening being fluidly connected to the medicament outlet opening by a medicament delivery conduit formed in the manifold component. The disclosed inhalers embodiments provide a variety of improvements to the design of the manifold component.

Disclosed is a dry powder inhaler for delivering medicament from at least one blister pack, each blister pack having a plurality of spaced-apart blister pockets containing doses of the medicament. The inhaler comprises: a housing for accommodating unused and used portions of the at least one blister pack together with a dispensing mechanism for simultaneously opening at least two blister pockets at a time; and a manifold component through which air can be drawn in use of the inhaler. The manifold component comprises: first and second air inlet openings for receiving external air a first air outlet opening for providing the external air to a first opened blister pocket and a first medicament inlet opening for receiving air-entrained medicament from the first opened blister pocket, the first air outlet opening and the first medicament inlet opening being arranged side-by-side to enable simultaneous communication with the first opened blister pocket; a second air outlet opening for providing the external air to a second opened blister pocket and a second medicament inlet opening for receiving air-entrained medicament from the second opened blister pocket, the second air outlet opening and the second medicament inlet opening being arranged side-by-side to enable simultaneous communication with the second opened blister pocket; and a medicament outlet opening for delivery of the air-entrained medicament from the first and second opened blister pockets to the user, the first and second medicament inlet openings being fluidly connected to the medicament outlet opening by a medicament delivery conduit formed in the manifold component. The first and second air inlet openings are fluidly connected to the first and second air outlet openings by respective first and second air conduits in the manifold component, wherein the air conduits are separately provided so that the external air from each of the first and second air inlet openings does not mix with the external air from the other of the first and second air inlet openings before reaching the first and second opened blister pockets.

An apparatus and method are provided for administering an inhaled drug to a person while simultaneously administering oxygen from a medical oxygen mask. The inhaled drug is from a pressurized metered dose inhaler (MDI), employing an extender tube about 3-10 cm long that fits into or over the mouthpiece of the inhaler. The MDI with extender tube is inserted into the mask and positioned so that the plume of drug travels through the extender when the MDI is actuated and is directed to just inside the mouth of the person. In an embodiment, an exhalation filter is provided to prevent contamination from infectious agents in the exhaled air from the person.

A system may include an external device and an inhaler. The external device may include a processor, a communication circuit, and memory. The inhaler may include a mouthpiece, medicament, a mechanical dose counter, and an electronics module comprising a processor and a communication circuit. The electronics module may record a dosing event when the inhaler is actuated, such as when the mouthpiece cover is opened, and send a signal indicating the dosing event to the external device. The external device may receive a mechanical dose reading of the mechanical dose counter, determine an electronic dose reading based on the signal indicating the dosing event, determine that a discrepancy between the mechanical dose reading and the electronic dose reading exceeds a threshold, and notify the user of the discrepancy, for example, by providing a notification to the user by way of a mobile application residing on the external device.

An inhaler comprising a valve having a valve volume of no more than 40 micro liters and a valve having a first layer comprising a silane and a second layer comprising a polyfluoropolyether silane—and albuterol.

A medicament delivery device (1) comprises an actuation mechanism by successive operation of which a predetermined number of unit doses of medicament can be dispensed. The device includes a locking mechanism for preventing further operation of the actuation mechanism after dispensing of said predetermined number of unit doses. The locking mechanism comprises a resilient member (51), a formation (18) with which the resilient member (51) is engageable to disable operation of the actuation mechanism, and a barrier member (20) that prevents engagement of the resilient member (51) and the formation (18) until said predetermined number of unit doses has been dispensed. The device (1) may be a dry powder inhaler.

Provided is a system (10) for determining a probability of an asthma exacerbation in a subject. The system comprises an inhaler (100) for delivering a rescue medicament to the subject. The inhaler has a use-detection system (12B) configured to determine a rescue inhalation performed by the subject using the first inhaler. A sensor system (12A) is configured to measure a parameter relating to airflow during the rescue inhalation. The system further comprises a processor (14) configured to determine a number of the rescue inhalations during a first time period, and receive the parameter measured for at least some of the rescue inhalations. The processor determines, using a weighted model, the probability of the asthma exacerbation based on the number of rescue inhalations and the parameters.

The model is weighted such that the number of rescue inhalations is more significant in the probability determination than the parameters.
