An inhalation device uses a base substance to generate aerosol to be inhaled by a user. The inhalation device includes a storage unit that stores information, a communication unit that receives information from another device when a first condition is satisfied, and a control unit that causes the storage unit to store the information received from the other device when a second condition is satisfied.

Disclosed is an electronic vaporizing device chip with air pressure sensing unit and working method thereof, where the chip includes an air pressure sensing unit, a control unit, a plurality of auxiliary resistors, a capacitor, and a plurality of pins, the air pressure sensing unit is configured to detect an air pressure generated inside the electronic vaporizing device during suction, a signal amplification module is configured to amplify and then transmit an air pressure analog signal detected by the air pressure sensing unit to an analog-to-digital conversion module, the analog-to-digital conversion module converts the air pressure analog signal into an air pressure digital signal, a data processing and calibration module processes and calibrates the air pressure digital signal and then converts it into an air flow quantity digital signal; the advantage is that an air pressure sensing function and an air flow quantity calculating function are combined.

A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.

A vaporiser insert for an electronic cigarette product comprises at least one electrical vaporiser for vaporising fluid supplied to the vaporiser and for supplying the vaporised fluid to an airflow, a main part having a lateral face which surrounds an airflow duct through which the airflow can flow, at least one fluid opening for supplying vaporisable fluid from the outside into the vaporiser insert and to the vaporiser being arranged on the lateral face of the main part. The vaporiser insert comprises a support for retaining the vaporiser, and the support comprises a passage opening that corresponds to the fluid opening in order to supply fluid to the vaporiser.

A substance delivery device and methods to promote treatment regimen compliance. A beneficial substance and an addictive substance are administered from a device delivering the substances by a user inhaling vaporized or atomized beneficial substances and addictive substances.

Disclosed are methods, apparatus and systems for treating a respiratory disorder in a patient. The apparatus comprises a pressure generator configured to generate a flow of air so as to provide ventilatory support to the patient; a transducer configured to generate a flow signal representing a property of the flow of air; and a controller configured to analyse the flow signal to estimate the inspiratory volume and the expiratory volume of a breath of the patient and servo-control the degree of ventilatory support to adjust an estimated tidal volume toward a target tidal volume. A gain of the servo-control is dependent on a difference between the estimated inspiratory volume and the estimated expiratory volume. The method comprises operating an apparatus or system in a similar manner.

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.

Described herein are an interactive apparatus and methods for sensing and measuring real-time characteristic patterns of a subject's use of a dry powder inhalation system. The inhaler device can be used in a wireless communication mode to communicate with a display to assess the subject's usage of the inhalation system concurrently as the inhalation is performed and thus the subject's inhalation can be evaluated as well as the performance of the inhalation system. The system can also detect the identity of the medicament, its dosage, lot, expiration, etc. and the characteristics profile of a dry powder formulation emitted from the inhalation system in use.
