1. A sweat-collection device for application to a substantially flat area of the human body, comprising a solid body having a face thereof forming an elongate concave sweat-collecting surface which gradually recedes from a rim lying wholly in a common plane to an axial bore that extends to the opposite face of said solid body, the maximum depth of said concave sweat collecting surface being such that the skin and flesh of said flat area of a human body to which the device is applied will bulge into contact with said sweat-collecting surface over substantially the entire area thereof when said rim is placed firmly against the skin of said flat area of the human body, leaving substantially no dead space in the interface between the bulged skin and said sweat-collecting surface, whereby body secretion pressure of sweat will force said sweat through said interface to said axial bore, said axial bore being adapted to connect with a length of flexible, sweat collector tubing at said opposite face of the solid body, and said solid body being adapted to be fastened against the said flat area of a human body so as to maintain firm placement of said rim and sweat-collecting surface against the skin. |
