The present technology relates to open respirator devices having sensors for measuring breath biometrics. For example, a respirator device (100) can include a mask component (102) that fits at least partially over a user's face and forms a gap (112) between a periphery of the mask component and the user's face, thereby forming a breathing chamber (108) between the mask portion and the user's face. A fan unit can provide air from the external environment to the breathing chamber for the user to inhale. In some embodiments, the air may be filtered before entering the breathing chamber and the fans may provide a positive pressure seal between across the gap. One or more sensors can be coupled to the mask component for measuring one or more metrics associated with the user's breath.

A dry-powder inhaler may include a first casing portion, a second casing portion, and a hinge arrangement connecting the first casing portion and the second casing portion. The dry-powder inhaler may be assembled by folding the first casing portion and the second casing portion together. The first casing portion may include a cavity for receiving a dose blister foil, said cavity being adapted to contain a dry-powder medicament. The first casing portion and the second casing portion when folded together may be adapted to form an inlet for allowing a lidding foil extending out there from and an outlet for providing the medicament.

The invention relates to a multilayer reconstituted plant sheet suitable for devices which heat tobacco without burning it, said reconstituted plant sheet having a high density.

The present disclosure relates to a drug administration device configured to administer a drug. In an exemplary embodiment the drug administration device includes a housing including first and second housing electrical contacts, a dispensing mechanism, a drug holder, a removable power supply including first and second power supply electrical contacts, and at least one protection mechanism in a first protecting configuration when the removable power supply is not received within the housing and in a second configuration when the removable power supply is received within the housing. In another exemplary embodiment the drug administration device includes a housing, a dispensing mechanism disposed within the housing, a removable power supply that is configured to be received within the housing, a sensor configured to determine remaining charge of the removable power supply, and a processor configured to modify operation of the drug administration device in response to data produced by the sensor.

The present invention relates to the technical field of an automatic detection trigger device, and discloses an automatic detection trigger device for a quantitative compressed administration aerosol. The automatic detection trigger device for the quantitative compressed administration aerosol includes a main machine body, wherein the main machine body consists of a main machine front cover, a main machine rear cover, a battery module and a driving assembly; the driving assembly includes a driving control module and a driving gear module; a charging port is formed at an outer side of the main machine front cover; a limiting pedestal is clamped at a bottom end of the main machine front cover; and an aerosol medicine is fixedly mounted at the bottom of an inner cavity of the main machine front cover. The automatic detection trigger device for the quantitative compressed administration aerosol detects an inspiration flow rate of a user in a medicine inhaling process through a flow sensor arranged in the driving assembly. When the inspiration flow rate reaches an ideal threshold, the device drives the aerosol to spray a medicine, and the medicine sprayed by the aerosol enters a lower respiratory tract such as a lung along with airflow, so that the problem of hand-mouth synchronous operation is solved, and the utilization rate of the medicine is greatly increased.

An atomiser, in particular an inhaler, for atomising a liquid active agent to form an aerosol, having, inter alia, an active agent reservoir, an atomiser nozzle and a pump arrangement, wherein a suction side of the pump arrangement leads into the active agent reservoir and a pressure side of the pump arrangement leads into the atomiser nozzle, and wherein the pump arrangement has a plunger that can be adjusted in a cylinder in the axial direction of the cylinder. A corresponding method is also described.

According to the invention there is disclosed a dispenser device for dispensing a medicament, the device comprising at least one component having a coating that comes into contact with the medicament during storage or use of the device on at least one surface thereof, the coating comprising a cross-linked non-diamond like carbon layer comprising 50 At % hydrogen or less and having an interface with the underlying surface of the component.

Provided is a system including a plurality of inhalers that each include a processor configured to determine a value of a usage parameter relating to use of the respective first inhaler, encrypt data based on the value, and transmit the encrypted data. At least two of the inhalers include different medicament, such as a rescue medicament and a maintenance medicament. The system includes an external device that includes a processor configured to distinguish between the encrypted data of each respective inhaler, determine respective usage information relating to each of the distinct types of medicament based on the respective encrypted data, and control a user interface (e.g., of the external device) to communicate the usage information related to each inhaler and/or each respective type of medicament.

An electrically-powered inhalation device for delivery of an aerosol to the oropharynx of a user comprises respective proximal and distal portions, the proximal portion including an inlet for a liquid, the distal portion including an aerosol outlet defining a mist-exiting location and a piezo assembly including an ultrasonically vibrable mesh membrane, for producing, upon electrical activation, a mist comprising droplets of the liquid, the mesh membrane defining a mist-generating location; and an intermediate portion disposed distally from the proximal portion and proximally from the distal portion, wherein the distal portion is dimensioned to vertically span the user's oral cavity from tongue to hard-palate when the user's lips and/or teeth are transversely engaged with the intermediate portion, so as to place the mist-exiting location in fluid communication with the user's oropharynx.

A device is provided for the self-administration of cannabinoids. The device includes a container having an opening on a first end thereof, a cap which releasably engages said first end of said container, and an assembly, including first and second modules, which is removably placed inside of the container. The first module includes a first element equipped with first and second threading, a receptacle for said solid medium, said receptacle being equipped with at least one surface feature which slidingly engages said first threading, and a solid medium which is seated in said receptacle and which contains at least one cannabinoid. The second module is equipped with a filter and has a first threading disposed on a first terminal portion thereof. Various accessories may be releasably attached to the container or assembly. Methods of using the device are also described.
