Hyperhidrosis diagnostic device and method

A device for diagnosing hyperhidrosis or for use in the diagnosis of hyperhidrosis comprising:

• a sweat capturing and collecting body forming a cavity therein and defining an opening leading to the cavity and being circumscribed by a contact surface for engaging the skin surface, wherein engagement of the skin surface by the contact surface provides for sealing the cavity thereby forming a chamber for capturing and collecting the sweat sample;
• an internal humidity sensor positioned within the cavity for measuring internal humidity within the chamber which corresponds to a sweat rate measurement;
• an internal temperature sensor positioned within the cavity for measuring internal temperature within the chamber which corresponds to a skin temperature measurement;
• an ambient humidity sensor for measuring ambient humidity in an ambient environment to the skin;
• an ambient temperature sensor for measuring ambient temperature in an ambient environment to the skin;
• a user interface;
• a controller in operative communication with the internal humidity sensor, the internal temperature sensor, the ambient humidity sensor, the ambient temperature sensor, and the user interface, the controller comprising a memory of controller executable code that when executed provides the controller with performing controller executable steps comprising:
• receiving the measured internal humidity within the chamber from the internal humidity sensor at an initial time stamp and at a final time stamp;
• receiving the measured internal temperature within the chamber from the internal temperature sensor at the initial time stamp and the final time stamp;
• determining an initial specific humidity measurement in the chamber at the initial time stamp and a final specific humidity measurement in the chamber at the final time stamp based on the internal humidity and internal temperature at the initial time stamp and the final time stamp respectively by performing calculations steps stored within the memory;
• determining a specific humidity gradient between the determined initial specific humidity and determined final specific humidity;
• receiving the measured ambient humidity near the skin from the ambient humidity sensor at the initial time stamp;
• receiving the measured ambient temperature near the skin from the ambient temperature sensor at the initial time stamp;
• modulating the specific humidity gradient based on the ambient humidity and ambient temperature at the initial time stamp by performing modulation steps stored within the memory thereby determining a modulated specific humidity gradient;
• comparing the modulated specific humidity gradient to a hyperhidrosis level and specific humidity gradient correspondence table stored within the memory thereby determining a hyperhidrosis condition;
• and
• communicating the determined hyperhidrosis condition via the user interface.
