A therapeutic vaporizer inhalation bag attachment system with an integrated valve is disclosed. The attachment system includes a body having a lumen extending between the two openings of the body, a bag coupling, and a valve positioned within the lumen. A method of using the inhalation bag attachment system is also disclosed.

The invention relates to a non-heated humidification device comprising a wick; a chamber for holding water in contact with the wick; and a gas inlet to the chamber, wherein the chamber and wick are configured to humidify gas passing through or over the wick at ambient conditions. The device may be modular and attachable to a flow generator. The device may comprise dual gas circuits and a control system for controlling the gas flow through the gas circuits in order to control the humidity of the gas output.

A humidification system can include a heater base, a chamber, and a breathing circuit. The heater base includes a heater plate positioned in a recessed region, and a heat conductive portion of the chamber is configured to contact the heater plate. The heater base includes a guard configured to control movement of the chamber into and out of the recessed region. The guard includes an anti-racking mechanism. The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.

A medicine vaporizer apparatus comprises a base with an upwardly extending heating element disposed within a rigid tube. Air is drawn into the rigid tube through an aperture in the rigid tube below the heating element and directed over the heating element to then be drawn through a flexible tube and through a filter or screen comprising an amount of medicine. Heated air flows over the amount of medicine and vaporizes the same, wherein the medicine is thereafter drawn into the lungs of a patient pulling the air therethrough with his or her mouth. Thermal separation and cooling of various parts prevents accidental injury to users and provides an inert air path for the air therethrough. The apparatus further provides controlled incineration and/or vaporization of the medicine.

Systems, methods, and devices for humidifying a breathing gas are presented. The system includes a source of pressurized breathing gas, a vapor transfer unit external to the source of pressurized breathing gas, a first gas tube connecting the source of pressurized breathing gas to the gas inlet of the vapor transfer unit and having a first length, a liquid supply having a heater that heats liquid, a first liquid tube coupling the liquid supply to the liquid inlet of the vapor transfer unit, and a second gas tube having a second length and connecting the gas outlet to a patient interface. The first length is greater than the second length. The vapor transfer unit includes a gas passage, a liquid passage, and a membrane separating the gas passage and the liquid passage. The membrane is positioned to transfer vapor from the liquid passage to the gas passage.

An apparatus for humidifying a flow of breathable gas includes a water reservoir and a water reservoir dock forming a cavity structured and arranged to receive the water reservoir in an operative position. The water reservoir comprises a reservoir base including a cavity structured to hold a volume of water, the reservoir base including a main body and a thermally conductive portion provided to the main body. The thermally conductive portion comprises a combined layered arrangement including a metal plate and a thin film, the thin film comprising a non-metallic material and including a wall thickness of less than about 1 mm. The thin film is adapted to form at least a bottom interior surface of the water reservoir exposed to the volume of water, and the metal plate is adapted to form a bottom exterior surface of the water reservoir.

The present disclosure is directed to a plurality of air quality devices configured to be held in a user's mouth and configured to increase at least one of humidity and temperature and constitution of air inhaled. There are passive and active systems that allow for improved physical and lung performance.

In alternative embodiments, provided are products of manufacture fabricated or manufactured as medical devices such as an inhaler, an ionizer, an asthma “puffer-like” device, a nebulizer or a nasal spray device, a respirator or a ventilator, a warm or a hot air delivery device, and/or a CPAP (continuous positive air pressure) device (for example, for managing or treating sleep apnea) or equivalent, for delivering one or a combination of medications or drugs, and optionally also warm or hot air, and optionally also ionized air. Products of manufacture are used for treating, preventing, ameliorating, slowing the progress of, decreasing the severity of or preventing a microbial infection, such as bacterial and viral infections, including the common respiratory viruses such as influenza virus, respiratory syncytial virus, picornavirus, parainfluenza virus, adenovirus, rhinovirus, human metapneumovirus, hantaviruses, enterovirus, a coronavirus infection, or a COVID-19 or a 2019-nCoV (or so-called Wuhan coronavirus) infection, or an infection caused by a virus in the subfamily Orthocoronavirinae, or a virus in the family Coronaviridae, or a virus in the order Nidovirales. In alternative embodiments, products of manufacture as provided herein administer combinations, or cocktails, of a drug or drugs by inhalation, for example, by use of aerosol, mist, liquid or powder formulations for inhalation.

A dispensing device for dispensing anesthetic in a breathing gas stream includes a flow duct (42) for an anesthetic-containing breathing gas stream, a control unit (5) and a first temperature sensor (54). An anesthetic feed device (45) has an evaporation surface (46) arranged in the flow duct (42). The first temperature sensor (54) detects the temperature of the evaporation surface (46) and sends a first temperature signal (T1) to the control unit (5). A second temperature sensor (53) detects the temperature of the breathing gas stream in the flow duct (42) and sends a second temperature signal (T2) to the control unit (5). The control unit (5) is configured to determine an anesthetic concentration based on the first and second temperature signals (T1, T2).

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.
