An external ear canal pressure regulation device including a fluid flow generator and an earpiece having a first axial earpiece conduit fluidicly coupled to the fluid flow generator, whereby the earpiece has a compliant earpiece external surface configured to sealably engage an external ear canal as a barrier between an external ear canal pressure and an ambient pressure.

A device and method for vaporizing phyto material. The vaporization device has a body that includes a heating chamber and a heating element usable to selectively heat different regions within the heating chamber. The heating chamber has perforated walls that define a chamber cavity. A lid is movably mounted to the body. The lid is moveable between open and closed positions. The lid has a cooling element positioned therein and an inhalation aperture that is fluidly coupled to the air cooler. In the open position, phyto material is loadable into the chamber cavity. In the closed position, the heating element is energizable to heat and vaporize the phyto material. In some embodiments, the chamber cavity is divided into a plurality of segments along the length of the heating chamber and the heating element is movable to heat and vaporize the phyto material in a specific segment.

A surgical humidification system includes a source of gas flow and a humidifier that receives the gas flow and outputs a humidified gas to a delivery conduit. The delivery conduit has an outlet and a suitable interface, such as a diffuser, is connected to the outlet. The interface can be positioned near or within an open surgical cavity of a patient to supply the humidified gas to the cavity. The system also includes a pressure relief arrangement that operates to relieve pressure from the system above a normal operating pressure. The pressure relief arrangement can be located in a non-sterile portion of the system, such as upstream from the humidifier, for example.

A method is disclosed comprising generating, by a first electronic vapor device, first usage data related to the first electronic vapor device, transmitting, by the first electronic vapor device, the first usage data to a central server, and receiving, by the first electronic vapor device, an indication of compliance with a vaping program.

This invention relates to a blower for a breathing apparatus. The blower comprising a bottom support with a stub axle, a top support with a stub axle, a motor core comprising a motor stator and rotor, and an impeller coupled to the motor core via a shaft, the shaft is rotatably coupled at a first end to the stub axle on the top support and at a second end via the stub axle on the bottom support.

Systems and methods are provided herein for control of humidification of a breathing gas for respiratory therapy. Control of humidification is provided by inverse adjustment of liquid flowrate, and this technique allows the user to adjust humidity independent of other therapy parameters such as gas temperature and gas flowrate.

A system and a method for generating a respirable dry powder aerosol (15) from a liquid solution or liquid suspension at a respirable dry powder aerosol volume flow (91). A liquid aerosol generating nozzle (3) generates from the liquid solution or liquid suspension a liquid aerosol (13) that is diluted by dilution gas (4) and dried in a cylindrical evaporation chamber (6) to generate a dry powder aerosol (14) that is subsequently concentrated by a cylindrical single linear slit aerosol concentrator (9). The system and method may include heliox as a gas, specifically dilution gas (4), for enhancing both the drying process in the cylindrical evaporation chamber (6) and for enhancing the concentration efficiency, but also as a nozzle gas (2) for enhancing generating the liquid aerosol (13) from the liquid solution or liquid suspension.

A pneumatic cooling device including a housing having a first end and a second end. A handle extends from an outer surface of the housing. An inlet is positioned at substantially the first end of the housing and is configured to receive a supply of medical grade air into the housing. An outlet is positioned at substantially the second end of the housing and is configured to deliver the supply of medical grade air outside of the housing. A pathway extends through the housing between the inlet and the outlet and is configured to passively move the supply of medical grade air between the inlet and the outlet.

A waste collection unit is provided that comprises a vacuum pump and smoke evacuation system including a blower and blower motor. The vacuum pump, the blower, and the blower motor, create noise. This noise is attenuated in first and second sound attenuating enclosures for the vacuum pump and the blower and blower motor. A cleaning system is also provided 100 with rotating liquid delivery devices. An actuator is operatively coupled to the liquid delivery devices to rotate the liquid delivery devices.
