A respiratory device for delivering gas to a patient comprises a gases passageway having proximal and distal ends, and a supplementary gas inlet in a side wall of the gases passageway. The supplementary gas inlet is adapted to direct gas along an interior surface of the gases passageway, such that the gas follows a generally helical path towards the distal end of the gases passageway.

A helmet for anesthesia, adapted to keep confined anesthetic gases and to administer them in a non-invasive fashion to a patient laying on an operating table, allowing to provide oxygen and/or anesthetic gases through tubes and fast access to the patient's head in case of emergency is described. The helmet has a lower half-shell and an upper half-shell, the lower half-shell being anatomically shaped to receive and support the nape and the neck of the laying patient, the upper half-shell and the lower half-shell having fastening means for fastening one to the other and being configured to be fitted one to the other and to the neck or torso of the patient to form a substantially airtight enclosure for enclosing head of the patient, at least one inlet port for gas supply and at least one outlet port for gas evacuation being on the lower half-shell and/or the upper half-shell.

A minimal weight patient interface device that delivers breathing gas to a user includes a cushion assembling including a support cushion assembly and a sealing member is described herein. In one exemplary embodiment, the support cushion assembly includes a wedge that is made of a high density foam received within a wedge receiving portion of the support cushion assembly. In the exemplary embodiment, the cushion assembly is formed by the sealing member fitting over the support cushion assembly. The sealing member, in one embodiment, is made of silicone, for example, having a low durometer value (e.g., between 5-10 Shore 00). Furthermore, in one embodiment, the patient interface device also includes a faceplate that is placed over the cushion assembly and is made of a thermoform, such as a high density foam laminated between two pieces of fabric, such as polyester.

A snore blocking helmet for comfortably minimizing snore impact on others includes a helmet body having a front portion, a rear portion, a right portion, a left portion, a top portion and a bottom perimeter forming an inside. The front portion has a visor aperture and a plurality of vent apertures extending through to the inside. A visor is rotatably coupled to the helmet body to cover and alternatively uncover the visor aperture. A plurality of fans is coupled within the inside adjacent the plurality of vent apertures. A control housing is coupled through the front portion. A plurality of controls is coupled to the control housing and is in operational communication with the plurality of fans. A power source is coupled to the control housing and is in operational communication each of the plurality of controls and the plurality of fans.

An altitude simulation assembly for an environmental chamber includes: at least one ambient air inlet; an air compressor downstream of said ambient air inlet for compressing the ambient air; at least one gas separation means downstream of the air compressor for separating the compressed air into hypoxic gas and hyperoxic gas; and, at least one fluid flow control means in fluid communication with the at least one gas separation means, for controlling the flow of hypoxic gas and hyperoxic gas to the environmental chamber. The at least one fluid flow control means is in fluid communication with at least one outlet port for supplying hypoxic gas from the gas separation means to the at least one outlet port, and hyperoxic gas from the gas separation means to the at least one outlet port. The fluid flow control means controls the oxygen concentration of gas to the environmental chamber.

A device and associated method for the dispensation of mists for therapeutic use, comprising: a dispensing member (2) for dispensing an air flow (3) within which micronized particles of a liquid or solid therapeutic substance are dispersed; a chamber (11) having at least one inlet (12) for said air flow (3) generated by the dispensing member (2) and at least one outlet (13) for said air flow (3) present inside the chamber (11) itself; and a communication conduit (10) interposed between said dispensing member (2) and said chamber (11) in order to introduce the air flow (3) into the chamber (11) itself; said chamber (11) being switchable between an operative condition of maximum volume in which it internally defines a space (20) for containing at least one user, and a non-operative condition of minimum volume suitable for transport and/or storage.

A system to regulate breathing air of a plurality of sealing and locking helmets and a plurality of supplied air respirators producing a plurality of lower pressure air supply of a plurality of people simultaneously using air regulators, valves, pressure sensors and a temperature sensor that measures temperature in the air module. The system includes a plurality of temperature sensors of measuring temperature of environment around each person of one of the sealing and locking helmets or supplied air respirators, a gas analyzer, an air module processor to control the valves, receiving data from the pressure sensors, controlling lower pressure air supply and presenting data on a display with real time updates that are presented in less than a few milliseconds providing a continuously imported status that achieves safe entry in a hazardous area with fewer accidents by operators, cleaning crew, inspectors, welders, installers, and loaders.

At least one embodiment of the invention provides a system comprising an inhalation exposure chamber and an aerosol delivery line connected to the inhalation exposure chamber. The aerosol delivery line is configured to produce a bi-directional and symmetrical presentation of aerosol to the inhalation exposure chamber. A laminar flow element is configured to create an ante-chamber where complete and turbulent mixing of the aerosol occurs. A radial exhaust and the laminar flow element enable laminar flow of the aerosol through the inhalation exposure chamber.

A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.
