Abstract: A respiratory therapy facemask configured to be positioned against a patient's face and adjacent the patient's mouth, includes a face plate configured for attachment to the patient and defining an opening, the face plate including a laterally extending track defining a slot. A tube rest assembly is configured for being slidably engaged in the slot and for securely accommodating an endotracheal tube. The tube rest assembly is configured for directly engaging the track for lateral movement in the opening.

Abstract: A respiratory cuff pressure regulator system is provided for use with a breathing tube equipped with an inflatable cuff, a tubule extending from the cuff and having a distal end communicating with an inside of the cuff, a proximal end having an inlet for inflating the cuff. The system includes a sealed housing enclosing an inflatable member and in fluid communication with the tubule, the sealed housing having an air inlet bore in fluid communication with the tubule inlet and with the interior of the inflatable member. A valve in the inlet bore is normally closed and opens for inflation of the inflatable member and ultimately the respiratory cuff. An equalizing biasing member in the sealed housing exerts a bias against the inflatable member. A pressure relief valve is provided in fluid communication with the tubule and is preset to open upon pressure in the tubule exceeding a predetermined amount.

Abstract: A humidifier apparatus for operating at an air pressure is disclosed for use with a respiratory therapy breathing apparatus that provides a breathable gas supply to patients requiring higher concentrations of liquid vapor and gas pressure. The humidifier apparatus includes a volume of liquid in fluid communication with a humidifier cartridge via a conduit. The conduit enables air to flow therethrough to equalize air pressure between the humidifier cartridge and the volume of liquid in response to liquid being supplied to the humidifier cartridge.

Abstract: A humidifier apparatus for operating at an air pressure is disclosed for use with a respiratory therapy breathing apparatus that provides a breathable gas supply to patients requiring higher concentrations of liquid vapor and gas pressure. The humidifier apparatus includes a feed liquid supply bag in fluid communication with a humidifier cartridge via a conduit. The conduit enables air to flow therethrough to equalize air pressure between the humidifier cartridge and the feed liquid supply bag in response to liquid being supplied to the humidifier cartridge.

Abstract: An improved heated cartridge humidifier for delivering humidified respiratory gases to patients. A humidifier housing includes a gas and water supply and a gas outlet. A humidifier base plate engages a heating element. The base plate includes a central heat conductive portion retained in an outer insulating portion which prevents the lateral dissipation of heat received from the heating element. The baseplate enhances the heat transfer to the water, and therefore, enhances the humidity of the gases.

Abstract: An aerosol nebulizer heater includes a housing with an inlet end for operational engagement with a nebulizer for the receipt of pressurized aerosol, a device for heating the aerosol, and a system for monitoring and controlling the temperature of the heated aerosol as the aerosol is passed through the housing and toward a patient, so that the patient receives the heated aerosol at a relatively constant temperature.

Abstract: A disposable heated cartridge humidifier for use with a collapsible water supply container and a heating device, the humidifier adapted for heating and humidifying a breathable gas to be inhaled by a patient. The humidifier includes a humidifier housing having an open upper end. A cap portion sealingly engages the open upper end of the humidifier housing to define a humidifier chamber, and has a gas inlet port, a gas delivery port, and a water delivery port adapted to receive water from the container, all of the ports being in fluid communication with the humidifier housing. The present heated cartridge humidifier also includes a water feed tube depending from an underside of the cap portion, and a float retaining tube circumscribes the feed tube, depends from the underside of the cap portion, is in fluid communication with the humidifier housing and retains a float therein.

Abstract: A nebulizer for use in administering medication to a patient includes a tubular body having opposed ends, a central portion defined by one-way valves and having a vial attached thereto, a nebulizer jet device disposed in the vial and including a multiple baffle arrangement configured to deliver a substantial amount of optimally-sized aerosol particles to a patient through inhalation at one of the tubular ends.

Abstract: A sealed swivel for a respiratory apparatus includes a first end configured for engagement with either an endotracheal tube or a face mask, a second end with a telescoping formation for insertion into a tubular respiratory connector, and a central portion with a sealing formation defining a swivel track and configured for creating a gas tight seal while permitting relatively free swivelling action.

Abstract: Inhalation therapy devices for vaporizing or nebulizing a liquid into a gas stream including containers having a fluid diffusion chamber disposed at the bottom portion thereof and adapted to receive an element for heating fluids within the diffusion chamber.
