SWEAT COLLECTING DEVICE

摘要

A sweat collection device includes an elongate concave sweat-collecting surface at a face thereof for placement over an iontophoresis-stimulated area of a patient's skin to collect sweat and pass it through an axial bore in the concavity. A length of flexible tubing is secured to the axial bore for receiving and storing the collected sweat. A chamber may be provided for holding the tubing in flat coiled condition. Collected sweat builds up within the tubing from the axial bore. The device can include markings to indicate when a minimum amount of sweat has been collected in the tubing and can indicated a range for collected sweat that takes into account variations in the tubing. An open end of the tubing can be flared for easy insertion of a blunt needle to extract sweat or a guide passage can guide insertion of the needle into the open end of the tubing.

主权项

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.
