An oro-nasal ventilation face mask worn by a patient includes a first chamber receiving airflow from an air source, a second chamber in fluid communication with the first chamber, a restrictive element positioned between the first chamber and the second chamber, and a headgear securing the first chamber and the second chamber to the patient. The second chamber includes a vent. Air flows between the first and second chambers through the restrictive element. When the first and second chamber are secured to the patient, the first chamber has a first air pressure, the second chamber has a second air pressure, and the first air pressure is greater than the second air pressure.

A hydrogen supply apparatus includes: an air path having an inlet and an outlet; a fan that is disposed in the air path and produces a flow of air from the inlet to the outlet; a first pipe having an end that forms a first supply port through which to supply hydrogen gas to the air path; a flow control device that is attached to the first pipe and adjusts a flow rate of the hydrogen gas; and a hydrogen gas sensor, disposed downstream of the fan or the end in a direction of flow of the air that detects a concentration of the hydrogen gas in the air path, where the end is disposed between the fan and the outlet or between the fan and the inlet in the air path.

A connector for positioning and reorienting a length of flexible tubing between a gas supply source and a gas use device to prevent binding and/or constriction. The connector includes a U shaped body section of rigid tubing with an inlet and an outlet. A flexible and/or resilient inlet connector is removably positioned on the rigid tubing inlet, and a flexible and/or resilient outlet connector is removably positioned on the rigid tubing outlet. The outlet connector is preferably (and typically) incorporated into the construction of the length of flexible tubing. The inlet connector end of the device, which may be permanently fixed to or removable from the device, is in turn removably attached to the gas supply source. Alternate embodiments include fixed and swiveling connector couplings.

In some embodiments, a face soaking device may have a vessel, a vessel neck gasket, and a breathing apparatus. The vessel may be configured to hold a liquid to submerge a face of a user or a portion thereof. The vessel neck gasket may be (removably) joined to the vessel. The vessel neck gasket may be configured to comfortably accommodate a front portion of the user's neck. The breathing apparatus may be in removable contact with: the vessel, with a head rest subassembly, and/or with the user. The breathing apparatus may be configured to permit the user to breathe while the user's face may be submerged within the liquid. When the vessel may be filled with the liquid to at least a sufficient level, the user may soak the face or the portion thereof, such that the skin being soaked receives a benefit.

Dialysis systems that remove air from a blood circuit are disclosed herein. In an embodiment, a dialysis system includes a dialysis fluid circuit, a blood circuit including an arterial line, a venous line, and an enclosure in fluid communication with the venous line, the enclosure configured to release air through a hydrophobic vent for priming the blood circuit, a blood pump configured to pump fluid through at least the arterial line, a first valve operable with the arterial line and a second valve operable with the venous line, and a pumping and valving algorithm operated after priming to remove air from the blood circuit to control the first and second valves and the blood pump to replace priming fluid with blood from a patient.

A smoking/hydrogen-suction device detachably accommodates a tubular portable heating-type smoking device main body and makes it possible to perform smoking and hydrogen suction. The smoking/hydrogen-suction device includes: a pair of positive/negative electrodes that are electrically conducted to or cut off from a positive electrode and a negative electrode of a battery by a control substrate; an electrolysis tank which is capable of storing water, into a lower portion of which the pair of positive/negative electrodes are inserted, and which has an injection port for an electrolyte or water and a hydrogen generation port fluidically connected to an air layer in the electrolysis tank; and a smoking device receiving portion having a tubular hole into which the smoking device main body can be inserted from above and having at its bottom portion a terminal that can be electrically connected to a terminal at a lower portion of the smoking device.

Provided are a bioactivation method for enhancing a neural activity and/or a blood circulation activity of a living body and a hydrogen generating device for executing this method. In the method, a gas mixture containing hydrogen and oxygen at predetermined concentrations is suctioned by spontaneous breathing continuously for a predetermined time. Moreover, this hydrogen generating device for executing the bioactivation method for enhancing a neural activity and/or a blood circulation activity of a living body includes a body cover member including a battery, a control substrate for controlling power supply from the battery, and a pair of positive/negative electrodes electrically conducted with or shut down from a positive electrode and a negative electrode of the battery by the control substrate.

A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. A filter can be preattached to the outlet of the mixture apparatus, allowing excess gas to be discharged therethrough and then atmospheric air to be drawn into the mixture apparatus through the filter for creating a therapeutic gas mixture.

Apparatus for enabling speech while a tracheostomy tube is in place includes a tracheostomy tube 1 with a vocalisation gas lumen 15 extending along its length and opening at one end externally of the tube above the sealing cuff 10 in the trachea T. A ventilator 2 is connected to the main bore 3 of the tube 1 to supply ventilation gas cyclically to the patient. The ventilator 2 also has an auxiliary outlet 29 connected to the vocalisation gas lumen 15. The auxiliary outlet 29 supplies vocalisation gas to the vocalisation gas lumen 15 only during the expiratory phases of ventilation. Alternatively, the apparatus includes a separate supply 50 of vocalisation gas connected with the vocalisation gas lumen 15 via a valve 52. The valve 52 is controlled by pressure in the main gas supply tubing 31 so that the valve is opened to enable the supply of vocalisation gas only during the expiratory phases of ventilation.
