Abstract
Methods for treating fluid overload in a subject comprise shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local sweating. Methods of the invention allow for removal of excess fluid from the interstitial compartment of the subject and treat fluid overload in the subject. Sweat stimulation systems comprise a chamber and first and second relative humidity sensors. The chamber is sized to fit around a body part of a subject, comprises an inlet and an outlet, and is configured such that air flows through the chamber from the inlet to the outlet. The first relative humidity sensor is operably located inside the inlet, and the second relative humidity sensor is operably located proximate the outlet.
Claims28
A fluid stimulation system comprising:
- a mobile, wearable apparatus comprising a chamber sized to fit around a body part of a subject and to stimulate fluid loss in the subject, wherein the fluid is sweat, and wherein at least a portion of the chamber provides a clear volume of air between the body part and one or more walls of the chamber upon receipt of air flow and subsequent expansion of the chamber, the chamber comprising an inlet and an outlet and the chamber being configured such that an air flow passes through the chamber from the inlet to the outlet to thereby create a controlled environment around the body part of the subject for stimulating fluid loss in the subject;
- first and second relative humidity and temperature sensors, wherein the first relative humidity sensor is operably located at the inlet and the second relative humidity sensor is operably located proximate the outlet;
- and
- a controller configured to monitor and control conditions of the controlled environment around the body part of the subject, the controller being communicatively coupled with at least the first and second relative humidity and temperature sensors and configured to calculate a sweat rate within the chamber based, at least in part, on data received therefrom and control and adjust inflow air temperature and/or air flow rate into the chamber based, at least in part, on the calculated sweat rate.
A method for treating fluid overload in a subject, the method comprising:
- shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local fluid loss, thereby removing excess fluid from the interstitial compartment of the subject and treating fluid overload in the subject,
- wherein the fluid loss is sweating stimulated by controlling an environment within a chamber of a mobile, wearable apparatus fitted around a body part of a subject, said environment being monitored and controlled by a controller configured to control and adjust inflow air temperature and air flow rate into the chamber based, at least in part, on a calculated sweat rate within the chamber based, at least in part, on data received from one or more relative humidity sensors configured to capture relatively humidity data associated with the chamber.
