A mouthpiece for an aerosol provision system. The mouthpiece includes at least one aerosol outlet channel for delivering an aerosol to a user of the mouthpiece. The mouthpiece includes at least one thermal element for controlling the temperature of a portion of the mouthpiece. The portion may include an exterior surface of the mouthpiece, and the thermal element may be configured for heating and cooling the portion of the mouthpiece. In this way, the thermal element may allow for thermal feedback to be provide to the user, such as to their mouth, lips, or tongue whilst they are operating the aerosol provision system.

A device has a power source having a high voltage terminal and a low voltage terminal, an oil-free gas compressor, a first molecular sieve, multiple ionized gas generators, an outer metal pipe, an inner metal pipe, a dielectric insulating ceramic sheet, and a gas outlet pipe. The first molecular sieve is connected between the oil-free gas compressor and the ionized gas generators, and is capable of filtering out molecules in the gas except for oxygen. The outer metal pipe and the inner metal pipe are electrically connected to the low voltage terminal and the high voltage terminal respectively. The dielectric insulating ceramic sheet is mounted between the outer metal pipe and the inner metal pipe, and forms an ionizing space, which communicates with the ionizing space, with the outer metal pipe.

Methods and systems are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a sump configured to hold a liquid anesthetic agent; an ultrasonic transducer coupled to a bottom of the sump and at least partially disposed within the sump; a vaporizing chamber fluidically coupled to the sump; and a heating element coupled to the vaporizing chamber and configured to increase a temperature of a surface disposed within the vaporizing chamber.

Embodiments provide swallowable devices, preparations and methods for delivering viable cells (VC) into the GI tract including GI wall tissue or other tissue site. Particular embodiments provide a swallowable device such as a capsule for delivering VC into an intestinal wall or other site. The VC can be contained within a tissue-penetrating shell disposed in the capsule that protects the VC as they pass through the GI tract until they are inserted into GI tract tissue or other location. The shell desirably has shape, size and material consistency to be contained in a swallowable capsule, delivered from the capsule into solid tissue by the application of force on the shell and biodegrade within the solid tissue to release the VC into the tissue. Within the shell or other structure the VC can be maintained in a viability-sustaining gel that preserves the viability of the VC for selected time periods.

A heating device is provided that creates inhalable aerosol that includes one or more heating elements and a temporary or permanently established cavity formed by a barrier between the heating elements and the external environment that envelops the heating elements to allow the insertion and removal of consumables from the cavity and allows for the replacement of the heating elements in the device.

An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece, a liquid container, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the container. The mesh material is configured to vibrate when the piezoelectric material is actuated, whereby the aerosol is produced. The aerosol may be inhaled through the mouthpiece. The device also includes circuitry and a power supply for actuating the mesh assembly. The mouthpiece, the container, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the container. The mesh material has a rigidity that is sufficient to prevent oscillations of varying amplitudes during actuation of the piezoelectric material of the mesh assembly for consistently producing the aerosol.

The subject matter described herein provides systems and techniques for enhancing a user’s performance. In particular, the physiological characteristics of the user can be altered toward target characteristics to bring about a particular physiological state in the user. Multiple physiological signals of the user may be sensed. Physiological characteristics indicative of a physiological state of the user may be determined. A differential between the physiological characteristics and selected target physiological characteristics may be determined. A selected energy signal associated with a correction action may be communicated to nerves associated with the user’s skin by outputting, using an energy generator, the energy signal toward the skin with one or more different energy types based on the differential. This may allow a particular targeted physiological state to be more rapidly brought about in the user.

A fluid warming device for warming fluids and delivering the fluids to a patient comprises an electrical heating component, a temperature sensor, and a control unit. The electrical heating component warms fluid passing through a fluid-carrying tube and may be positioned along the fluid-carrying tube at a desired location or embedded in the fluid-carrying tube while the control unit is positioned such that the display and user inputs are accessible to a caregiver. The control unit activates the electrical heating component until the fluid-carrying tube is warmed to a desired temperature within a Thermal Neutral Zone (TNZ) as sensed by the temperature sensor.

A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.

A heatable conduit for use in a respiratory apparatus for delivering breathable gas to a patient includes a first segment comprising one or more heater wires and a second segment comprising one or more heater wires. Each of the first and second segments comprises a spirally wound elongate body. In addition, the one or more heater wires of the first and second segments are configured to be connected in use to at least one controller such that, in a first mode, power is provided to the one or more heater wires of the first segment and no power is provided to the one or more heater wires of the second segment.
