The inhaler includes a housing having regions for accommodating unused and used portions of the medicament carrier, a mouthpiece component extending from the housing and through which a user is able to inhale, a dispensing mechanism arranged in the housing for moving a medicament dose of the medicament carrier to the dispensing position, and a mouthpiece cover being rotatably connected to the housing for sequential movement about a rotation axis from a first position in which the mouthpiece component is completely covered to a second position in which the mouthpiece component is completely covered, and from the second position to a third position in which the mouthpiece component is completely uncovered, the second position being between the first and third positions.

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.

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.

The principles and embodiments of the present invention relate to methods and systems for safely providing NO to a recipient for inhalation therapy. There are many potential safety issues that may arise from using a reactor cartridge that converts NO.sub.2 to NO, including exhaustion of consumable reactants of the cartridge reactor. Accordingly, various embodiments of the present invention provide systems and methods of determining the remaining useful life of a NO.sub.2-to-NO reactor cartridge and/or a breakthrough of NO.sub.2, and providing an indication of the remaining useful life and/or breakthrough.

A tank for accumulating oxygen enriched air from an oxygen concentration device is disclosed. The oxygen concentration device includes a canister including a nitrogen-adsorbent material. A compressor is coupled to the canister. The compressor compresses air for the canister to produce oxygen enriched air in a swing adsorption process. The tank includes a closed container for collecting oxygen enriched air produced in the canister. An inlet is coupled to the container. An outlet in the container allows a patient to inhale the collected oxygen enriched air. An adsorbent material within the container adsorbs oxygen enriched air added to the tank from the canister.

Embodiments provide an oxygen supply device having multiple operational states including a first state and a second state. In the first state, the oxygen supply device is controllable to a local control instruction such that the oxygen supply device can be operated by a user physically located within a proximity of the oxygen supply device. In the second state, the oxygen supply device is only controllable to a remote-control instruction such that the oxygen supply device can be operated by a user remote to the oxygen supply device. For example, the user can be located in an office remote to a location of the oxygen supply device, which, for example, may be placed at a patient's home. In the second state, the user is enabled to control the oxygen supply device from a device associated with the user in the remote location.

An aerosol-generating system (includes a cartridge, a liquid aerosol-forming substrate, and an aerosol-generating device. The cartridge includes a cartridge housing and a solid aerosol-forming substrate. The aerosol-generating device includes a cavity configured to receive at least a portion of the cartridge, an airflow inlet, and an airflow sensor. The airflow sensor is in fluid communication with the airflow inlet and the cavity). The aerosol-generating device includes a bypass air inlet in fluid communication with the cavity, an electric heater configured to heat the liquid aerosol-forming substrate, a power supply, and a controller. The aerosol-generating system is configured so that the cartridge housing substantially prevents airflow through the bypass air inlet when the cartridge is received within the cavity.

An adapter set that is attached to artery-side and vein-side shunt connectors-that are provided on a blood circuit. The adapter set includes: an artery-side adapter that has one end thereof connected to the artery-side shunt connector, has the other end thereof connected to a drainage port that is provided on the outside of the blood circuit, and thereby connects the artery-side shunt connector and the drainage port fluid tight; and a vein-side adapter that has one end thereof connected to the vein-side shunt connector, has the other end thereof connected to a supply port that is provided on the outside of the blood circuit, and thereby connects the vein-side shunt connector and the supply port fluid tight. The structure of the other end of the artery-side adapter and the structure of the other end of the vein-side adapter are different.

A medicament delivery device is presented having a housing that is arranged to accommodate a medicament container, a drive unit operably arranged to act on the medicament container upon activation, an activation mechanism operably arranged to be operated by a user, an activation preventing mechanism operably arranged to prevent the activation mechanism to be activated, an usage management module arranged to be operated by a user, which usage management module is designed as an attachable unit to the medicament delivery device. First keying elements are arranged on the device and on the usage management module designed to interact with each other when attaching said usage management module, such as to cause a deactivation of the activation preventing mechanism to allow operation of the activation mechanism. The usage management module can include a monitoring circuit arranged to monitor the use of the medicament delivery device.

A medicament delivery device is presented having a housing that is arranged to accommodate a medicament container; a drive unit operably arranged to act on the medicament container upon activation; an activation mechanism operably arranged to be operated by a user; an activation preventing mechanism operably arranged to prevent said activation mechanism to be activated; an identification module arranged to be operated by a user, which identification module is designed as an attachable unit to the medicament delivery device; mechanical keying elements arranged on said device and on said identification module designed to interact with each other when attaching said identification module; first electrical keying elements comprised in said identification module, wherein said electrical keying elements are capable of obtaining identification information, such that the identification information obtained is compared to stored data and authenticated by the identification module, and wherein the authentication causes a deactivation of the activation preventing mechanism to allow operation of the activation mechanism.
