An oxygen concentrator comprises a product tank that is fluidly coupled to at least one sieve bed, and a product gas accumulator tank that is fluidly coupled to the product tank via a first conduit and to an outlet port via a second conduit, wherein the first conduit and the second conduit are disposed to allow at least a portion of product gas to flow from the product tank to the outlet port.

Condensation or rain-out is a problem in medical circuits and previous attempts to manage and/or prevent rain-out have resulted in relatively expensive and/or difficult to manufacture medical circuit components. The subject patent provides an improved medical circuit component for managing rain-out. In particular the component may be an improved breathing tube, or insufflation system limb comprising a helically corrugated tube preferably incorporating a heater wire.

A respiratory humidification system for providing humidification to gases that pass through a gas passage way before being provided to an airway of a patient is disclosed. The respiratory humidification system may include a liquid flow controller providing a controlled flow of liquid, a heating system including a heating surface configured to be located in a gases passage way and provide humidification to gases passing through the passage way, wherein the heating system receives the controlled flow of liquid, and one or more hardware processors providing deterministic control of a humidity level of gases passing through the gas passage way by instructing the liquid flow controller to adjust the controlled flow of liquid received at the heating system.

A scent pod is attached to a face mask. The scent pod includes a scented body for providing a scent to the user and a scent body holder for holding the scented body and securing the scented body to the face mask. A face mask includes a support for attaching to a user's face and a scent pod for providing a scent. The scent pod is attached to the support. The scent pod provides the scent to an internal chamber of the face mask.

A device 10 withdraws a breathing gas stream (A) from a ventilation system (B) and transports the breathing gas stream (A) to a gas analysis system (G). The device 10 has a tubular configuration with an inner side (41) and with an outer side (42) and includes two tube sections (11, 11) and a drying stage (12, 14, 22) with an inner side (43, 43) and with an outer side (44, 44), and at least one liquid storage device (13, 21). The drying stage (12, 14, 22) includes a gas-tight and moisture-permeable material that transports moisture from the inner side (43, 43) of the drying stage (12, 14, 22) through the gas-tight and moisture-permeable material to the outer side (42) of the tubular device (10). The drying stage (12, 14, 22) and/or the liquid storage device (13, 21) is arranged at least partially between the two tube sections (11, 11).

A breathing gas delivery system comprising a gas flow controller, at least one breathing apparatus, and at least one first length of tubing coupling the breathing apparatus to the gas flow controller. The gas flow controller has a body having an on/off switch, at least one gas input, at least one gas output, and at least one control mechanism for controlling flow of gas to the gas output. The breathing apparatus comprises a T-shaped gas input, a breathing bag coupled to the T-shaped gas input, a second length of tubing having two opposed ends, wherein one end is coupled to the other arm of the T-shaped gas input, a filter coupled the second length of tubing, and a nasal assembly coupled to the filter.

A nasal insert may include a wall in the shape of a tube, the wall including a first end defining a first orifice and a second end defining a second orifice. The first end may have a diameter, diagonal measurement, or cross-sectional area larger than that of the second end. The first end may define at least one break in the wall, so that the first end incompletely encircles the first orifice. The second end may completely encircle the second orifice.

The present invention provides a gas generator and comprises an electrolytic cell and a water-blocking device. The electrolytic cell is used for electrolyzing electrolyzed water to generate a gas with hydrogen. The electrolytic cell has an outlet for outputting the gas with hydrogen. The water-blocking device is set on the outlet for preventing the electrolyzed water from flowing out when the electrolytic cell is tilted by a tilt angle. The gas pathway of the invention will be closed by the water-blocking device when the gas generator is toppled, thereby preventing the electrolyte-rich electrolyzed water from flowing out.
