Abstract

The purpose of the disclosed thermostat is to prevent age-related diseases, induced by long term cool indoor temperatures. As people age, the body produces progressively less heat while aging-impaired vasoconstriction results in progressively more heat being lost. This age-induced cold stress requires ever greater use of vasoconstriction or behavior to maintain the body'"'"'s heat balance. When behavioral regulation becomes diminished with age, vasoconstriction becomes progressive throughout life. In at risk elderly, an ongoing mild indoor cold stress can unknowingly maximize negative feedback vasoconstriction leaving it unable to further defend core body temperature. Before hypothermia occurs, positive feedback vasoconstriction activates as a defense mechanism. Like inflammation and fever, this beneficial defense mechanism can also cause harm when its use becomes excessive. The therapeutic function of this medical device is to sense skin temperature and use it to modify the indoor environment, keeping thermoregulation within the effective range of negative feedback vasoconstriction.

Claims

1. A medical device to maintain thermoregulation within an effective range of reflex-mediated vasoconstriction for an individual when the individual is subjected to a mild indoor cold stress, said medical device comprising:

a remote toe temperature sensor for placement on or near a toe of the individual, the remote toe temperature sensor providing a toe temperature; and

a dual input thermostat adapted for connection to an HVAC system for adjusting an air temperature in an operational zone to a set point temperature and further adapted for connection to the remote toe temperature sensor to receive the toe temperature, the dual input thermostat including at least one control for the adjustment of a high limit room temperature setting and a low limit room temperature setting to delimit a range of temperature operation for the HVAC system and further including an air temperature sensor providing the air temperature within the operational zone;

wherein the dual input thermostat is configured to receive temperature inputs from at least the remote toe temperature sensor and the air temperature sensor and is configured to adjust the set point temperature of the HVAC system relative to the air temperature inversely and proportionately based on the toe temperature provided by the remote toe temperature sensor, the set point temperature being bounded by the range of temperature operation for the HVAC system delimited by the high limit room temperature setting and low limit room temperature setting of the dual input thermostat.

2. The medical device of claim 1, wherein the remote toe temperature sensor in communication with the dual input thermostat is in wireless communication with the dual input thermostat.

3. The medical device of claim 1, wherein the at least one control for the adjustment of the high limit room temperature setting and the low limit room temperature includes a pair of controls including one control for controlling the high limit room temperature setting and one control for controlling the low limit room temperature setting.

4. The medical device of claim 1, wherein the at least one controls are disposed on a housing of the dual input thermostat.

5. The medical device of claim 1, wherein the air temperature sensor is located within the dual input thermostat.

6. The medical device of claim 1, wherein the dual input thermostat is configured such that, when the dual input thermostat receives a temperature input from the toe temperature sensor, an adjustment the set point temperature of the HVAC system relative to the air temperature is time delayed to dampen the response to the toe temperature sensor.

7. The medical device of claim 6, wherein the dual input thermostat further comprises a visual indicator configured to indicate a warning when dampened toe temperature falls below a predetermined value corresponding to the skin activation temperature of locally-mediated vasoconstriction.

8. The medical device of claim 7, wherein the visual indicator is a colored light.

9. The medical device of claim 1, wherein the medical device protects the individual against indoor cold-induced disease, regardless of age of the individual.

10. The medical device of claim 1, wherein the medical device protects the individual against indoor cold-induced hypertension, regardless of age of the individual.

11. The medical device of claim 1, wherein the medical device maintains the indoor heat balance of a body of the individual, with or without the use of behavioral thermoregulation.

12. The medical device of claim 1, wherein the medical device protects the individual against an age-related progression of vasoconstriction, regardless of age of the individual.

13. The medical device of claim 1, wherein the medical device protects the individual against indoor positive feedback vasoconstriction.

14. The medical device of claim 1, wherein the medical device protects the individual against indoor hypothermia.

15. The medical device of claim 1, wherein the medical device connects a closed loop control system of the dual input thermostat with a thermoregulatory closed loop control system of a body of the individual to create a third interactive loop therebetween, while still allowing the closed loop control system and the thermoregulatory closed loop control system to control autonomously.

16. A method of operating the medical device of claim 1, the method comprising the steps of:

measuring the toe temperature using the remote toe temperature sensor and the air temperature using the air temperature sensor;

providing the toe temperature from the remote toe temperature sensor and the air temperature using the air temperature sensor to the dual input thermostat;

adjusting the set point temperature of the HVAC system relative to the air temperature inversely and proportionately based on the toe temperature provided by the remote toe temperature sensor, the set point temperature being bounded by the range of temperature operation for the HVAC system delimited by the high limit room temperature setting and low limit room temperature setting of the dual input thermostat.

17. The method of claim 16, wherein the step of providing the toe temperature from the remote toe temperature sensor to the dual input thermostat involves wirelessly transmitting the toe temperature to the dual input thermostat.

18. The method of claim 16, further comprising the steps of receiving an input from the at least one control to adjust at least one of the high limit room temperature setting and low limit room temperature setting and of adjusting the range of temperature operation for the HVAC system.

19. The method of claim 16, wherein the step of adjusting the set point temperature of the HVAC system relative to the air temperature occurs in response to a change in the toe temperature.

20. The method of claim 19, wherein the step of adjusting is time delayed to dampen the response to the toe temperature sensor.
