Description of the Related Art It is well known that carbon dioxide is released from the surface of human skin, and measuring the amount of carbon dioxide released from the surface of human skin is important for measuring respiration, circulation, metabolism, etc. It is important from a physiological point of view. In particular, it is extremely important to simultaneously measure the amount of carbon dioxide gas released from the skin surface of each part of the body.

が出来る。The method for measuring carbon dioxide gas released from the skin surface of the present invention uses a packaging material (carbon dioxide trapping piece) filled with barium hydroxide. The surface is made of a carbon dioxide permeable sheet, and the carbon dioxide gas permeable sheet side of this packaging material is adhered and fixed to the skin surface of the site to be measured, and after a lapse of a predetermined time, removed from the skin surface and inside the packaging material. The carbon dioxide gas collected by barium hydroxide is measured by scientific means.
That is, according to the present invention, by bringing the packaging material having the above-mentioned configuration into close contact with the skin surface, all of the carbon dioxide gas released from the adhered portion passes through the carbon dioxide-permeable sheet and is trapped with barium hydroxide. By being collected, the carbon dioxide gas released only from the closely contacted part is collected,
The amount of carbon dioxide gas released is measured by chemically quantitatively measuring this. This makes it possible to directly measure the carbon dioxide gas released from a specific part of the skin surface, and to obtain an accurate carbon dioxide gas release amount.
Furthermore, since the packaging material can be made thin and compact, it can be in close contact with a large number of parts at the same time, and the amount of carbon dioxide gas released at different points can be measured at substantially the same time point.

These are obtained by filling the barium hydroxide with each other and then sealing the periphery by heat adhesion or the like, and the effective area of the carbon dioxide permeable sheet is set to a predetermined area.

The packaging material is opened and the barium hydroxide (reagent) inside is immersed in a certain amount of distilled water to form an aqueous solution of barium hydroxide. An indicator phenolphthalene-alcohol solution is added to this aqueous solution, and neutralization titration is performed with an oxalic acid aqueous solution.
