The present disclosure provides an aerosol delivery device and a liquid delivery and atomization assembly for use with an aerosol delivery device. In one implementation, the liquid delivery and atomization assembly comprises a liquid composition, an atomization assembly, and a liquid delivery component configured to transport at least a portion of the liquid composition to the atomization assembly. The liquid delivery component comprises at least one microchannel configured to deliver the portion of the liquid composition to the atomization assembly, and the microchannel includes a variable flow characteristic defined along at least a portion of the microchannel, the variable flow characteristic being configured to control the flow of the portion of liquid composition through the microchannel.

A pump set for use with a pumping apparatus includes tubing for carrying a liquid. A valve mechanism is mounted to the tubing between an inlet section and a pump engagement section. The valve mechanism includes a first port connected to the inlet section of the tubing, a second port connected to the pump engagement section of the tubing, and a valve disposed between the first and second ports. The valve includes a stem rotatably mounted within a stem holder. The stem includes a flow passage extending through the stem and having an open V shape whereby a narrow open end of the flow passage communicates with the first port and a wide open end of the flow passage communicates with the second port to place the inlet section of the tubing in communication with the pump engagement section of the tubing.

A supplement inhalation and hydrogen inhalation device for enabling supplement inhalation administration and hydrogen inhalation includes: an electrolysis tank in which a pair of positive/negative electrodes are inserted, electrolysis tank being capable of storing an electrolytic solution or water, the pair of positive/negative electrodes being either energized or not energized; a supplement generation cartridge configured to be energized to be heated for releasing a supplement-containing gas; control means configured to control the pair of electrodes and/or the supplement generation cartridge each to be either energized or not energized; and an inhalation vessel configured to mix hydrogen and a supplement-containing gas and guide the gases to an oral inhalation opening or a nasal inhalation opening.

Provided for may be a pump failsafe apparatus for use with a pump motor, the pump failsafe apparatus comprising a foot pedal configured to generate a first signal when depressed and a second signal when released. The apparatus may comprise a power supply having an internal logic controlled power switch, the power supply in electrical communication with at least the pump motor, wherein the internal logic controlled power switch includes an active state (ON) and an inactive state (OFF). The apparatus may further include an overspeed detector, an under voltage detector in electrical communication with at least the power supply, the under voltage detector configured to measure a logic voltage, and a pump cartridge detector.

An aerosol-generating system includes a cartridge and an aerosol-generating device configured to receive the cartridge. The cartridge includes a cartridge housing and a cartridge aerosol-forming substrate within the cartridge housing. The cartridge housing has a first end, a second end, a first side between the first end and the second end, and at least one aperture on the first side. The aerosol-generating device includes a device housing, a liquid aerosol-forming substrate, an electric heater, a power supply, and a controller. The device housing defines a cavity, a cavity air inlet, and a cavity air outlet. The cavity is configured to receive the cartridge such that an airflow from the cavity air inlet to the cavity outlet flows through the cartridge via the at least one aperture during an operation of the aerosol-generating system.

A vapor-generating system includes a cartridge, a vapor-generating device and a piercing element. The cartridge includes a cartridge housing configured to hold a solid vapor-forming substrate within the cartridge housing interior, a liquid storage housing configured to hold a liquid vapor-forming substrate within the liquid storage housing interior, and a frangible seal on the liquid storage housing. The vapor-generating device includes a device housing at least partially defining a cavity, an electric heater, and a power supply. The piercing element is configured to pierce the frangible seal of the cartridge to expose the liquid storage housing interior to be in fluid communication with the electric heater based on the vapor-generating device coupling with the cartridge such that the device housing at least partially receives the cartridge into the cavity. The electric heater is located externally from the piercing element.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a control unit configured to operate in a hybrid automated mode during a PD treatment. A processor in the control unit is configured to engage a pump during a fill phase of the PD cycle. The volume of fluid (e.g., dialysate) transferred to a patient line during the fill phase is monitored. After a dwell period, the pump is disengaged at the start of a drain phase of the PD cycle. Disengaging the pump can include: configuring valves of a disposable cassette to bypass the pump chambers of a disposable cassette; activating a bypass valve to shunt the patient line to a drain line; or moving a roller assembly of a peristaltic pump. The fluid transferred from the patient line to the drain line is monitored during the drain phase of the PD cycle.

An inhalation device controller includes a power supply unit configured to supply power to an atomizer including a heater configured to heat an aerosol source, a detection circuit configured to detect a resistance value of the heater, a processor configured to generate a control signal in accordance with a smoothed signal generated by smoothing information obtained using the detection circuit, and a holding portion configured to hold the atomizer in a detachable state. The holding portion includes a first electrical contact contacting a third electrical contact of the atomizer, and a second electrical contact contacting a fourth electrical contact of the atomizer. Information obtained using the detection circuit is affected by stress applied to the first to fourth electrical contacts when attaching the atomizer to the holding portion.

An aerosol delivery device may include a rechargeable power source configured to provide power to generate an aerosol, device electronics configured to generate the aerosol responsive to application of the power from the power source, and an authentication module. The authentication module may include a separate chip or circuit board relative to the device electronics. The authentication module may be inserted into the aerosol delivery device between the power source and the device electronics to control provision of the power to the device electronics for generation of the aerosol or between the power source and a charge port of the aerosol delivery device to control charging of the power source.
