The present disclosure relates to a continuous positive airway pressure (CPAP) device which sends, into an airway of a user, air sucked into the device. A body unit as a first unit has a cylindrical first lead-out portion through which air circulates. A base unit as a second unit has a third introduction portion to which the first lead-out portion is to be connected. A body-side terminal is provided as a first terminal with conductivity at the first lead-out portion of the body unit. A base-side terminal is provided as a second terminal with conductivity at the third introduction portion of the base unit. The body-side terminal is in contact with the base-side terminal while the body unit is attached to the base unit.

A respiratory ventilation apparatus configured to deliver a respiratory gas to a patient interface is provided. The apparatus may include a gas pressurization unit configured to generate a pressurized respiratory gas, a gas inlet port configured to introduce the respiratory gas into the respiratory ventilation apparatus, a gas outlet port configured to discharge the pressurized respiratory gas to a respiration tube, a detection module configured to detect the pressure of the pressurized respiratory gas, at least one non-volatile memory configured to store a plurality of parameters and a plurality of programs, and one or more controllers. The one or more controllers may be configured to initiate the respiratory ventilation apparatus upon a boot operation, and/or initiate a program that constantly reads information from the detection module, and controls the pressure of the pressurized respiratory gas using the information read from the detection module and at least one parameter.

Systems and methods are provided for delivering anesthetic agent to a patient. In one embodiment, an anesthetic vaporizer includes a housing defining a sump, the sump configured to hold a self-contained supply of liquid anesthetic agent, a heating element electrically coupled to an electrical mating component, a gas inlet passage and a gas outlet passage, a manifold fluidically coupled to the gas inlet passage and the gas outlet passage, the manifold coupled to the housing and forming a gas-tight seal with the sump, and a quick disconnect pneumatic system coupled to the gas inlet passage and the gas outlet passage, sealing the gas inlet passage and the gas outlet passage from atmosphere.

An aerosol supply device includes: an accommodating part (cartridge) configured to accommodate a liquid; an atomization unit configured to atomize the liquid to generate an aerosol; a discharge port configured to discharge the generated aerosol to the outside of the aerosol supply device; and a volatilization preventing part (solenoid valve or duckbill valve) capable of opening and closing a passage (first passage or second passage) through which at least one of the liquid or the aerosol flows between the accommodating part and the outside of the aerosol supply device.

This aerosol supply device is provided with: an accommodating section (cartridge) that accommodates a liquid; an atomizing unit that atomizes the liquid to generate an aerosol; and an atomizing amount adjusting unit (gyro sensor and control unit) that adjusts the atomizing amount of the atomizing unit. The aerosol supply device is characterized in that the atomizing amount adjusting unit (gyro sensor and control unit) stabilizes the atomizing amount regardless of the inclination of the aerosol supply device within at least a certain range.

The present disclosure includes a method for vaporizing a product of a plurality of different products including receiving, by a processor of a vaporizing device, a desired dosage amount that is indicative of an amount of a compound to release during one or more inhalation events. The method includes determining, by the processor, an occurrence of a current inhalation event and during the current inhalation event determining, by the processor, an inhalation pressure being applied to a container that contains the product; determining, by the processor, a predicted dosage that is indicative of a predicted amount of the compound that has been released in the vapor during the current inhalation event based on the inhalation pressure; and selectively adjusting, by the processor, a vaporizing temperature being applied to the product by the vaporizer based on the desired dosage and the predicted dosage.

The present disclosure is directed to an aerosol delivery device and a holder for use with a removable substrate cartridge. In one implementation, the holder includes a main body defining a proximal end and a distal end, the main body further providing an aerosol passageway that extends through at least a portion of the main body, and a heat sink portion. At least part of the receiving chamber is located in the heat sink portion, and the heat sink portion is configured to dissipate heat from a substrate cartridge. Some implementations further include a cartridge retention assembly and a sliding assembly. The sliding assembly is configured to slide relative to the main body to and from at least a loading position, wherein the cartridge retention assembly is configured to receive a substrate cartridge, and a use position, wherein the cartridge retention assembly is configured to retain a substrate cartridge.

The present invention relates to an apparatus for flow tempering medical irrigation fluids and to a method carried out with the aid of this apparatus.

A working fluid cassette for an intravascular heat exchange catheter includes a frame holding two closely spaced, square polymeric membranes in tension. Working fluid from the catheter is directed between the membranes. The cassette is closely received between two refrigerant cold plates to exchange heat with the working fluid, which is circulated back to the catheter.

A respiratory ventilation apparatus configured to deliver a respiratory gas to a patient interface is provided. The apparatus may include a gas pressurization unit configured to generate a pressurized respiratory gas, a gas inlet port configured to introduce the respiratory gas into the respiratory ventilation apparatus, a gas outlet port configured to discharge the pressurized respiratory gas to a respiration tube, a detection module configured to detect the pressure of the pressurized respiratory gas, at least one non-volatile memory configured to store a plurality of parameters and a plurality of programs, and one or more controllers. The one or more controllers may be configured to initiate the respiratory ventilation apparatus upon a boot operation, and/or initiate a program that constantly reads information from the detection module, and controls the pressure of the pressurized respiratory gas using the information read from the detection module and at least one parameter.
