The preferred embodiment of the invention provides a gas generator comprising an ion membrane electrolytic cell and an atomized/volatile gas mixing tank. The ion membrane electrolytic cell comprises an ion exchange membrane, a cathode chamber and an anode chamber. An anode electrode is set in the anode chamber, and a cathode electrode is set in the cathode chamber. The ion exchange membrane is set between the anode chamber and the anode chamber. When water is electrolyzed by the ion membrane electrolytic cell, oxygen is generated by the anode electrode and hydrogen is generated by the cathode electrode. The atomized/volatile gas mixing tank coupled to the ion membrane electrolytic cell accepts the hydrogen generated from the ion membrane electrolytic cell and generates an atomized gas to mix with the hydrogen for generating a healthy gas.

A sanitary extubation cover used to cover an endotracheal tube and a patient's face in order to accommodate sanitary extubation. The sanitary extubation cover includes a mask and a cover which covers the endotracheal tube. If the patient coughs, the cough would be directed into the mask and the endotracheal tube (which is covered by the cover) but contaminants from the cough would be suppressed from spreading into the open air. The mask can have an air cushion at the bottom of the mask in order to securely press against the patient's face. Th ask can also have a solid silicone base at the bottom of the mask in order to securely press against the patient's face.

A medical drape which is positioned over the head and upper torso of a patient is disclosed which includes a head flap, a head portion, a torso portion, and two oppositely disposed arm portions. The head flap is of a sufficient length to extend about the backside of the patient's head. The head portion includes oppositely disposed side wings which aid in covering the head of a patient. Each arm portion includes an access slot extending through the arm portion.

Each arm portion includes an access slot extending through the arm portion.

A collapsible healthcare barrier device may be moveable between collapsed and erected positions. The device may include a left side panel, a front panel, a right side panel, and a top panel. The left side panel is hingedly connected to the left side of the front panel. The right side panel is hingedly connected to the right side of the front panel. The top panel is hingedly connected to the top of the front panel. The front panel includes at least one passageway through which a health care provider may extend his or her hands and arms to render care to a patient. The top panel may include a left lip member and a right lip member. A back flap may be hingedly connected to the rear of the top panel. The back flap may include a left wing member and a right wing member.

A breathing assistance apparatus that comprises a housing with inner and outer walls and an upper surface, wherein the walls and upper surface are integrally formed as a single part to avoid seams or joins between the walls to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks. Also disclosed is a control system for a heating element of a humidifier which provides a secondary or back up protection mechanism to disable power to the heating element if a first electronic protection circuit does not cause the first switching member to disable power to the heating element.

A healthy gas generating system for generating healthy gas for inhalation by a user includes an electrolysis device, a gas mixing device, and a backfire barrier. The electrolysis device electrolyzes water to generate a gas with hydrogen. The gas mixing device includes a mixer and a vibrator for mixing the combination gas with an atomized gas to produce the healthy gas. The backfire barrier is configured on the output of the gas mixing device or the gas passage of receiving the combination gas to avoid the backflow of the gas.

A system includes a nasal cannula having a flexible tube configured to transmit oxygen gas to a user, an optical fiber coupled to the nasal cannula and configured to transmit light having a frequency spectrum range at least including that of light resulting from combustion of the nasal cannula while transmitting the oxygen gas to the user, a detector operatively coupled to the optical fiber and configured to detect the light transmitted through the optical fiber, and a valve. The valve is configured to be actuated to interrupt the transmission of the oxygen gas to the user through the nasal cannula in response to a signal from the detector.

An oxygen concentrating apparatus includes an oxygen supply source, an attaching member, and a photodetector. An oxygen discharger is attached to the attaching member while oxygen from the oxygen supply source is supplied to the oxygen discharger. The photodetector is disposed in the oxygen concentrating apparatus and on an extension of an oxygen supply passage of the attaching member.
