A charging system for charging a vaporizer device is described. The charger may be adapted to control the output voltage to the vaporizer device, thus improving charging efficiency and reducing waste heat generation. Related systems, methods, and articles of manufacture are also described.

A sieve bed assembly monitoring system is disclosed. The system includes a sieve bed assembly including a canister having an intake; adsorbent material to produce oxygen enriched air from compressed air in a swing adsorption process; and an identification device including identification data for the sieve bed assembly, wherein the identification data is capable of uniquely identifying the sieve bed assembly. The system includes an oxygen concentrator having a retention mechanism to retain the sieve bed assembly, a compressor supplying compressed air to the intake of the canister, a controller, a transceiver and a reader operable to read the identification data from the identification device. The controller reads the identification data and transmits the read identification data via the transceiver. A remote external device receives the read identification data from transceiver.

A handheld tattoo device comprises an elongated body comprising a grip section and an upper section above the grip section. The grip section comprises a coupling end configured to removably couple with a needle module comprising one or more needles. The upper section comprises a needle actuator for actuating the one or more needles through a shaft extending through the grip section, and a battery power source for supplying electrical power to the needle actuator. The device also comprises a user interface on the upper section, the user interface comprising a display and a touch sensor for detecting finger gestures of a user; and a control circuitry in the upper section for controlling the power supplied to the actuator by the battery power source based on user input received through the user interface.

A patient interface for supplying a flow of breathable gas to the airways of a patient may comprise a heat and moisture exchanger (HME). The HME may be positioned in a flow path of the flow of breathable gas. The HME may absorb heat and moisture from gas exhaled by the patient and the incoming flow of breathable gas to be supplied to the patient's airways may be heated and moisturized by the heat and moisture held in the HME.

Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound dressing. The wound dressing can comprise an absorbent material, an electronics unit comprising a negative pressure source, the electronics unit integrated within the wound dressing and at least partially encapsulated by a flexible film. The electronics unit can include translucent or transparent components that allow light to travel through to reach adhesives or coatings on the electronic components that would otherwise be obscured.

Systems and methods are provided for portable and compact nitric oxide (NO) generation that can be embedded into other therapeutic devices or used alone. In some embodiments, an ambulatory NO generation system can be comprised of a controller and disposable cartridge. The cartridge can contain filters and scavengers for preparing the gas used for NO generation and for scrubbing output gases prior to patient inhalation. The system can utilize an oxygen concentrator to increase nitric oxide production and compliment oxygen generator activity as an independent device. The system can also include a high voltage electrode assembly that is easily assembled and installed. Various nitric oxide delivery methods are provided, including the use of a nasal cannula.

An atomizer for an electronic cigarette and an electronic cigarette are presented. The atomizer comprises a substrate, a heating device and a cover member. The substrate is provided with a mounting space. One end of the heating device is inserted into the mounting space and partially extends to the outside through the substrate to form a controlling member, and the other end is exposed to the outer surface of the substrate. When the controlling member is pressed into the substrate by an external pressing force, the heating device is pushed to move toward the outside of the substrate along the mounting space and partially extends out of the substrate. The cover member is detachably mounted to the substrate and covers the controlling member. The technical solution of the present invention is convenient for the user to disassemble and replace the heating device inside the atomizer, effectively saving the use cost.

An aerosol-generating article for an aerosol-generating system is provided, the article including: a storage portion having an outlet; an aerosol-forming substrate contained within the storage portion; and a vaporisable barrier to seal the outlet, in which the barrier includes one or more polymers, has a polymer content of greater than or equal to 1 percent by weight, is configured to be vaporised during a first heating cycle of the article during first use of the article in the system, further includes one or more metal salts, and the salts are selected from the group consisting of metal alginates, metal benzoates, metal cinnamates, metal cycloheptanecarboxylates, metal levulinates, metal propanoates, metal stearates, and metal undecanoates. An aerosol-generating system, and a method of manufacturing an aerosol-generating article, are also provided.

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.
