The invention refers to a new type of ventilator, which has a compact block, in which rigid pipes and a gas supply container are integrated. The new structure is more compact than conventional superstructures. In addition to this improvements have been made to the therapy gas delivery and nebulization.

Breathable outsole (11) for footwear, in which the outsole has a two-layer structure. The two-layer structure contains an elastic and water vapor-permeable inner layer (1) and an outer layer (2) that covers less than 70% of the inner layer (1). The breathing activity of outsole (11) is guaranteed by the preferably microporous structure of inner layer (1) and the configuration of outer layer (2). The configuration of outer layer (2) is such that the surface of inner layer (1) available for water ...

Breathing equipment with a circuit for breathing gas and with a flat calcium hydroxide absorber (1) is cooled by an evaporating agent with improved cooling. A gas volume flow of at least 60 L per minute is admitted to the outer surface (14) of the calcium hydroxide absorber (1) receiving the evaporating agent by at least one gas delivery device (5). The evaporating agent is delivered to the outer surface (14) of the calcium hydroxide absorber (1) by an admitted pressure from an evaporating agent...

A breathing device for assisting patients to breath by maintaining positive airway pressure during the breathing cycle comprises a breathing channel in fluid communication with an exhaust channel extending from a junction therebetween. A gas inlet is arranged so as to introduce gas into the breathing channel. A positive pressure may be maintained in the breathing channel wherein the axis of the gas inlet channel is laterally offset at the point at which the gas inlet channel introduces the gas i...

An improvement to a combination of an SCBA system for providing bottled air to a user and a PAPR system for purifying ambient air for use by a user wherein a sensor is included to determine the oxygen content of the breathing gas and the presence of contaminations in the atmosphere to control operation of the two systems depending on the contaminated condition of the ambient air and the oxygen content of the ambient air.

A power assisted respirator comprises a facepiece for covering at least the nose and mouth of the wearer which has an outlet provided with a one-way exhale valve which is openable to permit air to flow out of the facepiece when a predetermined pressure P is established within the facepiece. A pump unit supplies air to the space within the facepiece. The pump unit may be connected to an inlet of the facepiece by a flexible hose or may be mounted directly on or in the facepiece. A filter canister ...

A breathing apparatus for supplying air to a helmet and/or protective clothing comprises a base plate; a core body secured to the base plate; an air driving device supported by the core body; an air inlet and an air outlet for the air driving device; an energy source secured to the base plate and connected to the air driving device for operating the same; an aerating hose coupled to the air outlet; and an air filter connected to the air inlet for filtering air driven through the air inlet, the a...

In a breathing apparatus having a pressurized tank of a breathable gas, pressure reducing means attached to the outlet of said tank, a pressure gauge line attached to said pressure reducing means, and a breathing tube, the improvement comprising a quick connect-disconnect fluid coupling fluidly connected to said pressure gauge line. The fluid coupling is adapted for attachment to a like fluid coupling on a second pressure gauge line so that upon attachment, two users can simultaneously utilize a...

A breathing apparatus primarily intended to be used in administering oxygen to a patient can be constructed so as to utilize a fluidic control device in such a manner as to conserve oxygen. The control device is connected to a supply of the gas to be administered to the user, to a reservoir type structure for temporarily storing this gas and a respiration structure such as a connected pair of tubes adapted to extend loosely into the nostrils of the user. On inhalation through the respiration str...

In a breathing apparatus of the closed circuit type wherein breathable air is recirculated with the removal of carbon dioxide and the replenishment of oxygen, the breathable air is cooled by causing it to flow through a conduit in heat exchange relationship with a reservoir containing a liquid refrigerant medium which has a boiling point below the maximum desired temperature of the breathable air supply. The reservoir is vented to allow escape of refrigerant gas through an adjustable pressure re...
