A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, and a frame component may be made in an overmoulding process that moulds the frame onto a pre-formed foam cushion. Such a moulding process may form a mechanical and/or chemical bonding of the foam and mask frame component. The mask frame component may be a shell of plenum chamber, such as for both nose and mouth. Various features of the cushion may further promote sealing and comfort for the under the nose design.

A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.

An airway pressure support system (2) includes a housing (4) having an air inlet opening (54), and a filter assembly (50) coupled to a plurality of receiving portions of the housing. The filter assembly is in fluid communication with the air inlet opening. The filter assembly includes a housing portion (62), a first filter media portion (64) attached to the housing portion, and first and second spring members (84, 86) attached to the housing portion, wherein the first and second spring members each have a floating portion and engage the plurality of receiving portions and cause a sealing force to be exerted against the filter assembly.

An ear mounted cannular nasal breathing filter provides an air mixing chamber to offset the effects of dry air caused by filtration by allowing for an admixture of filtered and pre-conditioned (humidified and heated) air. The air chamber features an internal or centered mixing chamber disposed below a one-way exhaust valve and above a filtering system. The air mixing chamber retains a predefined volume or percentage of exhausted breath that is mixed with a predefined volume or percentage of filtered air, with the filtered air originating as ambient air. An air chamber assembly is retained and supported upon a user by an ear mount system comprising a) a flexible wire that conforms to the ear join, or b) an upper arm in telescopic connection with a lower arm, with the two arms in dynamic tension by use of an internal elastic member, providing a tensioned fit to the ear join.

A gas sensor for the detection of gases and vapors in air is particularly for the detection of anesthetic gases. A method for the detection and for the monitoring of such gases is also provided including detecting anesthetic gases with the gas sensor.

Disclosed are adsorbent materials that comprise a porous material having a continuous silica phase coated with a carbon layer, and a water-insoluble precipitate comprising a metal cation and an anion disposed substantially evenly throughout the adsorbent material. In some examples, the plurality of pores can have an average characteristic dimension of from 0.1 Å to 100 Å. The water-insoluble precipitate can be formed in the plurality of pores of the porous material by contacting the porous material with a first aqueous solution comprising a metal cation; and contacting the porous material with a second aqueous solution comprising an anion; wherein the metal cation and the anion combine to form the water-insoluble precipitate in the plurality of pores of the porous material, thereby forming the adsorbent material.

The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air. The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.

A rescue device for a choking victim and a method of rescuing a choking victim is provided. The device includes a first tube that is configured to be inserted into the victim's mouth so as to assist in dislodging a foreign object in the victim's windpipe by creating a low-pressure environment within the victim's mouth. The device further includes a second tube that is configured to allow a rescuer to create the low-pressure environment in the victim's mouth by sucking on a second tube of the device. A filter is positioned between the first and second tubes to reduce sanitary concerns and to prevent the foreign object from becoming lodged in the rescuer's windpipe.

An emergency respirator ventilator that comprising an air cylinder and piston/piston rod for compressing an air bag to transmit air to a patient, e.g., during situations where fully equipped ventilators are not immediately available.

A device includes a body defining a respiration passage in fluidic communication with a filter fitting disposed on a first end of the body and a mask fitting disposed on a second end of the body, and a treatment passage in fluidic communication with the mask fitting. A treatment fitting is disposed on the body and is coupleable to a treatment source such that a seal in the treatment fitting transitions from a closed state to an open state to allow fluidic communication between the treatment source and the treatment passage. The device configured to permit (i) inhalation air and/or exhaled breath to be drawn and/or expelled through the filter fitting, the respiration passage, and the mask fitting and (ii) a respiratory therapeutic to be drawn from the treatment source coupled to the treatment fitting, through the treatment passage, and through the mask fitting.
