Device for adjustment and/or conditioning of the co2 content of the inhaled air

A device for automatic adjustment and/or regulation of the CO2 (carbon dioxide) content of inhaled air for treatment of hyperventilation, comprising:

• a by-pass element, leading inhaled and exhaled air of a self-breathing patient in two directions,
• an exhaled air pipe and inhaled air pipe connected to the by-pass element, where valves enabling one direction flow are placed and arranged in the pipes, and
• a blending vessel connected to the inhaled air pipe comprising a fresh air input aperture and a CO2 input aperture,
• wherein
• a CO2 vessel is connected to the CO2 input aperture,
• a measuring tool determining the CO2 content of the inhaled air is connected to the inhaled air pipe,
• a measuring tool determining the CO2 content of the exhaled air is connected to the exhaled air pipe,
• measuring tools determining the oxygen content of exhaled and inhaled air are connected to the exhaled air pipe and to the inhaled air pipe,
• the output apertures of the measuring tools are connected to the input aperture of a control unit,
• an exhaled air vessel, where one output aperture of the vessel is connected to the blending vessel the other output aperture is connected to a pipe opened to the atmosphere,
• the output aperture of the control unit is connected to the valve adjusting the blending rate of the blending vessel and so adjusting the CO2 content of the inhaled air by increasing the CO2 content of the inhaled air to the exactly appropriate level to avoid hyperventilation by using the CO2 content of the air either directly exhaled or stored in the exhaled air vessel and/or using the CO2 content of the CO2 vessel, and/or using the O2 content of the fresh air and/or of a compressed air vessel, and
• in a particular case to the bypass element of the device there is a breathing-counter connected and the output of the breathing-counter is connected to the appropriate input of the control unit.
