A chamber adaptor and a manufacturing method thereof. The chamber adaptor includes: a housing provided with a gas inlet, a gas outlet, a chamber inlet, and a chamber outlet, where the gas inlet is configured to be removably connected to a main board device, the gas outlet is configured to be removably connected to a respiratory pathway, the chamber inlet is configured to be removably connected to an input end of a chamber for storing liquid and the chamber outlet is configured to be removably connected to an output end of the chamber, the chamber adaptor further includes a control circuit and at least one sensing apparatus, where the at least one sensing apparatus is arranged on one end of the control circuit closer to the gas outlet and extends into a gas output channel.

A tub for a humidifier includes an inner tub configured to hold a supply of water; an outer tub configured to receive the inner tub, the outer tub including a bottom and a cavity being formed between the bottom and the inner tub when the inner tub is received in the inner tub; and a valve configured to control a flow of the supply of water from the inner tub to the cavity. The valve is closed to prevent the flow when the inner tub is received in a first position in the outer tub and open to permit the flow when the inner tub is received in a second position in the outer tub.

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.

An apparatus and method for providing heat exchange in the lungs of the mammal during partial liquid ventilation are provided. The apparatus and method can control delivery and removal of partial liquid ventilation to the lungs of a mammal by responding to pressure change in the lungs to minimize danger of causing barotrauma to the patient.

A valve unit (10) for a fluid supply chamber (20) of a respiratory support system (100) that provides humidified respiratory gases is provided. The valve unit comprises a first port (11) and a second port (12) and a fluid passageway (14) formed therebetween. The valve unit further comprises a valve (13) arranged in the fluid passageway (14) for controlling the flow of fluid between the first port (11) and second port (12). The valve unit is arranged to seal against an interior surface (21) of the fluid supply chamber (20) proximate the first port (11) and against an exterior surface (22) of the fluid supply chamber (20) proximate the second port (12) when the 10 valve unit (10) is connected to the fluid supply chamber (20).

A respiratory humidification device includes: a casing; a separator wall to divide an interior space into filling and humidification chambers, wherein a bottom edge of the separator wall leaves a space between it and the casing bottom to define a passage allowing water to flow atop the casing bottom between the chambers, and enabling the water level to rise enough to block the passage to prevent respiratory gas from passing therethrough; a valve and float within the filling chamber to control water flow into the filling chamber to prevent the water level from rising higher than a threshold; and wherein an outer wall of the casing and the separator wall cooperate with the water surface within the humidification chamber to define an elongate tube-like pathway through which respiratory gas proceeds along a path extending generally parallel to the water surface within the humidification chamber to be humidified.
