A heat generating unit is incorporated in a mask in order to actively supply warm steam, and also drug vapor, to the nose and throat, and moisturize the upper respiratory tract. It is preferable that a metal powder, salt, and water be contained in the heat generating unit, and that an exothermic composition that releases steam in conjunction with the oxidation reaction of the metal powder be used therein. It is preferable that either an inhalation valve or exhalation valve be provided in the mai...

An air warming device to facilitate breathing comprising a thin wall air warming chamber having a plurality of cells which extend vertically when the device is worn and placed against the chest region of the user. Each cell has a relatively large opening at the bottom and a relatively smaller opening at the upper end. A first manifold extends across the bottom having an upwardly facing open wall in communication with the large openings at the bottom of each cell and having a small opening to adm...

A warm air mask comprising a facial covering configured to form an upper edge positionable above the nose of a wearer, a lower edge positionable beneath the chin of a wearer, and side edges positionable beyond the ears of a wearer; a plurality of oval inhale ports formed in the covering and extending therethrough, each inhale port including a flap to open with the inhaling of a wearer and to close with the exhaling of a wearer. An exhale port is formed in the covering and extending therethrough,...

A breathing apparatus for athletes to warm and moisturize inhaled air has an elongate housing having both lateral and downward curvatures with respect to the position of the apparatus when positioned over the mouth of the wearer. An oral aperture for disposition over the mouth of the wearer is disposed centrally of the housing on the concave side of the lateral curvature. A plurality of corresponding pairs of spaced-apart leaf members or vanes disposed within the housing. The leaf members are di...

Described briefly, according to a typical embodiment of the present invention, a breathing mask is provided which has the intake air heater and heat and moisture exchange media located below the nose and situated for minimum exposure to heat transfer to the exterior. The mounting thereof is somewhat cantilevered from the mask, to minimize direct heat transfer to the exterior. Electric heating element means are provided and supplied from an energy pack mounted in the mask itself at a relatively l...

Protection for the nasal passages comprising an oblong ellipsoid-shaped solid of soft pliable impervious material called a sealer or arrester for inserting and closing off the nasal cavities. When the same solid is made of soft, pliable and porous material, its function will be that of a nasal filter when inserted in the nasal cavities.

A cold weather breathing device which heats and humidifies air to be breathed. A face mask which covers the mouth and nose includes intake and exhaust ports each equipped with a one way valve. An open sided conduit which is U-shaped in section extends in opposite directions from the mask along opposite sides of the head. A corrugated metal partition divides the conduit into side by side intake and exhaust passages. The intake passage is adjacent the open side of the conduit so that incoming air ...

There is provided for a heated humidifier used in respiratory therapy a method of lowering the heating cost, reducing the waste of humidifier fluid, lowering the compliance volume and reducing the labor costs attending water level maintenance by placing a removable, space filling, volume reducing insert into the reservoir of existing heated humidifiers. The resulting modified humidifier may be used both for adult patients as well as pediatric and neonatal patients.

The present invention is directed to a much safer and less expensive way of providing portable oxygen from a gas concentrator for patients who do not want to be tied to a stationary machine or restricted by present oxygen technology. In one preferred embodiment, the present invention splits off some of the excess capacity gas flow from a gas concentrator which is then stored via liquefaction. The stored gas can then be used as a portable supply. A portion of the oxygen gas flow generated by the ...

Breathing circuits for medical respiratory devices which have an inspiratory conduit for delivery of respiration-related aeriform substances to a patient, may also have a expiratory conduit, and, in any case are arranged to communicate with a patient interface, such as a wye (14), and have heating means for respiration-related aeriform substances in at least the inspiratory conduit. The heating means may be a heated-liquid heating tube (11) within at least the inspiratory conduit or an electrica...
