Patent Images
1. An apparatus for use with a device for testing skin moisture by passing a gas having a known moisture content over the skin area to be tested to pick up the moisture in the skin, comprising:
- a housing for attaching to the skin surface to be tested;
a cylindrical probe on the housing for sealingly engaging the skin surface to be tested;
a gas inlet and a gas outlet means in fluid communication with the enclosed volume of said cylindrical probe;
a limit means on the housing for engaging the skin surface adjacent the area to be tested;
said limit means including a plurality of concentric rings having a generally triangular cross-section; and
said probe extending a predetermined distance past the limit means to provide a sufficient seal between the probe and skin to be tested when the probe is pressed against the skin area to engage the skin at a deeper level than the engagement made by the concentric rings of the limit means when they engage the skin surface so that the apparatus is uniformly positioned on any user to provide accurate test results.
