Methods and apparatuses (e.g., systems, devices, etc.) for delivering a nebulized drug agent in the nasal passages concurrent with the lungs.

System for assisting a patient in speaking, comprising at least one ventilation apparatus and a patient interface, the ventilation apparatus comprising at least one controllable respiratory gas source and being designed to identify two or more respiratory phases, at least inspiration and expiration, of the patient, and the patient interface having at least one speaking tube and a respiratory tube and being configured to conduct speaking gas to the patient via the speaking tube and to conduct respiratory gas to and/or from the patient via the respiratory tube. The system is configured to provide speaking gas to the patient at least temporarily in a speaking mode in order to enable speaking.

A ventilation device comprising a controllable respiratory gas source and a programmable control unit being configured to perform the following: determining the respiratory gas flow, which is used to determine whether an inspiration or an expiration is present, regulating the pressure for an inspiration (IPAP) and an expiration (EPAP), wherein the control unit determines a typical expiration time over n breaths, the control unit lowers the pressure from the IPAP to the EPAP taking into account the typical expiration time in such a way that the pressure drop to the EPAP is already reached to the extent of at least 85% after a proportion of the typical expiration time in the range of 40-60% of the typical expiration time, the EPAP after completion of the pressure drop being predefined until the end of the typical expiration time.

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.

Apparatus and methods are described for use with a portion of plant material that includes at least one active ingredient. A vaporizing unit includes a heating element configured to heat the plant material, and a sensor configured to detect an indication of airflow rate through the vaporizing unit. Control circuitry is configured to receive an indication of the airflow rate through the vaporizing unit, and, in response thereto, to determine a smoking profile that is desired by the user. The control circuitry drives the heating element to vaporize the active ingredient of the plant material by heating the plant material according to the determined smoking profile. The control circuitry dynamically updates the smoking profile in response to changes in airflow rate over the course of a smoking session. Other applications are also described.

A non-invasive ventilation system may include at least one outer tube with a proximal lateral end of the outer tube adapted to extend to a side of a nose. The at least one outer tube may also include a throat section. At least one coupler may be located at a distal section of the outer tube for impinging at least one nostril and positioning the at least one outer tube relative to the at least one nostril. At least one jet nozzle may be positioned within the outer tube at the proximal lateral end and in fluid communication with a pressurized gas supply. At least one opening in the distal section may be adapted to be in fluid communication with the nostril. At least one aperture in the at least one outer tube may be in fluid communication with ambient air. The at least one aperture may be in proximity to the at least one jet nozzle.

A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control component to control the heating element to activate and vaporize components of the aerosol precursor composition. The control body also includes a gas sensor configured to detect a presence of gas in an environment of the control body, and the gas sensor or control component are further configured to control operation of at least one functional element of the aerosol delivery device in response to the presence of gas so detected.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

An electronic smoking device (10) is provided including a power supply portion (12) comprising a power supply (18), an atomizer/liquid reservoir portion (14) comprising a liquid reservoir (34) storing a liquid, and an atomizer (26) adapted to atomize the liquid stored in the liquid reservoir (34) when operated by the power supply (18). The atomizer (26) extends away from the liquid reservoir (34) in a first direction (L). The atomizer (26) comprises first atomizer sections (28a, 28b, 28c, 28d), wherein each of the first atomizer sections defines an opening (50a, 50b, 50c, 50d) that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.

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.
