The Nasal Cannula Cover will be utilized as an aid in infection prevention. The Nasal Cannula will be encased within the Nasal Cannula Cover. The Nasal Cannula Cover aids in the prevention of many foreign objects from being directly transmitted to the nasal cavity byway of the Nasal Cannula. In no way does the Nasal Cannula Cover replace existing sanitization or maintenance methods used for care of the Nasal Cannula. A Nasal Cannula Cover should be an accessory to every Nasal Cannula used or sold as an aid in infection prevention

A medical carbon monoxide generator provides for a solid carbon material that may be heated at substantially normal atmospheric pressure to provide a source of medical quality carbon monoxide. The heating source may be an electrical filament or laser controllable by a microcontroller to provide accurate delivery rates and amounts. In one embodiment, a replaceable cartridge holding the carbon material may be used.

A positive end expiratory pressure retention valve has a tube house forming an air flow chamber between a first port connected to a medical air supply tube and a second port connected to a medical air supply source. A balloon house is connected to the tube house and houses a balloon in a balloon chamber connected to the air flow chamber. The balloon occludes the air flow chamber when inflated.

Aspects and embodiments relate to a nasal cannula manifold. The nasal cannula manifold comprises: an inlet configurable to receive pure oxygen or oxygen-enriched therapeutic gas from a gas supply line and at least one outlet insertable into a nasal opening to deliver said oxygen or oxygen-enriched therapeutic gas. At least a portion of the outlet comprises a polymeric material which is fire resistant in the presence of the oxygen or oxygen-enriched therapeutic gas. Aspects and embodiments recognise that it may be possible to provide a comfortable, yet fire resistant, nasal cannula by providing at least an inner portion of the nasal cannula manifold which is fire resistant in an oxygen enriched environment, yet retaining a soft pliable feel to at least an outer, client interface, region of a cannula outlet, such that patient comfort is maintained.

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 fluid passage/stop body, component, housing and apparatus, a ventilation treatment device, and an oxygen supply control method. The fluid passage/stop body comprises a sliding plate and a flexible connecting member; the flexible connecting member is connected to the sliding plate; the flexible connecting member is used for connecting to a first channel wall of a first fluid channel of a fluid passage/stop apparatus; and the sliding plate is used for moving, driven by the pressure of a fluid in the first fluid channel, to drive the flexible connecting member to flexibly deform. The fluid passage/stop body is simple in structure, can drive, in actual use, a passage/stop member to safely and reliably achieve the passage/stop of a fluid, and can significantly improve, in a ventilation treatment device, the safety of oxygen supply of the ventilation treatment device.

A portable breathing machine includes a body case (100), wherein: a fan box (101), a cut-off device (108) and a control device (113) are arranged in the body case (100); a fan (8) is arranged in the fan box (101) through a fan noise reduction device (102); an air outlet of the fan box (101) is connected with an internal breathing tube (107); the cut-off device (108) is arranged on the internal breathing tube (107); an air outlet of the cut-off device (108) is connected with an external breathing tube (104) and a mask (105); the fan noise reduction device (102) includes a lower flexible cover (3) and an upper flexible cover (5); the lower and upper flexible covers cooperate to form an enclosed cavity for containing the fan (8). A working noise of the breathing machine is decreased to below 15 decibel.

A fire protection device includes a housing, a valve body, a torsion spring, and a meltable member, a fluid passage is provided in the housing, the fluid passage is provided with a first opening and a second opening, the first opening and the second opening are used for connecting with a pipeline of an oxygen therapy instrument or a patient end, respectively; the valve body is located in the fluid passage and is rotatably connected to the housing; the valve body is provided with an accommodating cavity, and the fluid passage and the accommodating cavity are two spaces independent from each other; the torsion spring is embedded in the accommodating cavity so as to drive the relative rotation of the valve body and the housing; and the meltable member is disposed on an inner wall of the fluid passage.

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.

The invention relates to a breathing assistance apparatus that may be configured to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks within the apparatus or impacts to the apparatus. In other forms, the apparatus may be configured to allow for easy assembly and/or safe operation.
