METHOD AND DEVICE FOR TRANSCUTANEOUS CARBONOMETRY Russian patent published in 2015 - IPC A61B5/08 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical diagnostics. A method for transcutaneous carbonometry involves the following stages: air intake pipe end is attached to a measuring point; a produced gas mixture with carbon dioxide is pumped through along a surface of distilled water added into a dielectric container; water conductivity are measured after contacting the gas mixture to determine the carbon dioxide concentration with the use of the preset calibration data. A device comprises the measuring dielectric container provided with the air intake pipes, an air pump, a matching unit connected to a personal computer. The measuring dielectric container is partially filled with distilled water. Two stainless steel electrodes and a heating resistor are immersed in water; their terminals are connected to inputs of the matching unit. Outputs of the matching unit are connected to inputs of the personal computer. One air intake pipe connects the measuring container and air pump. A second one is applicable to connect to a skin surface area, which is exposed to the carbonometry.

EFFECT: inventions enable performing the carbonometry for an unlimited period of time without skin heat-up.
