Abstract

An apparatus for measuring skin permeable gas, which can be used to obtain clinical information by noninvasive and bloodless operations and are useful for in-home medical care and health management. The device for collecting skin permeable gas includes a cylindrical member including a spiral groove, a cover disposed on the upper surface of the cylindrical member, a gas-introducing section connected to the cover, a gas delivery section connected to the cover, and a sealing member for sealing the groove of the cylindrical member and for maintaining air contained in the groove at a predetermined temperature. After components in the air maintained at a predetermined temperature are analyzed, the sealing member is detached from the cylindrical member and the cylindrical member from which the sealing member is detached is then brought into intimate contact with skin of a subject to collect the skin permeable gas.
