Hot and cold immersion tub and temperature control system therefor

A system, comprising:

• a tub, the tub comprising a port at or adjacent to a bottom of the tub;
• a hot tempered reservoir storing water at a first temperature;
• a cold tempered reservoir storing water at a second temperature lower than the first temperature;
• a catch reservoir for receiving water evacuated from the tub;
• pipes connecting the hot and cold tempered reservoirs to the tub to introduce the water into the tub and to evacuate water from the tub;
• a first set of one or more pumps for pumping water from the hot tempered reservoir to the tub;
• a second set of one or more pumps for pumping water from the cold tempered reservoir into the tub;
• a first temperature sensor within the tub for sensing a temperature of water within the tub;
• a second temperature sensor within the hot tempered reservoir for sensing a temperature of water in the hot tempered reservoir;
• a third temperature sensor within the cold tempered reservoir for sensing a temperature of water in the hot tempered reservoir;
• a control system comprising one or more processors for selecting one of the first and second pumps to pump water from one of the hot and cold tempered reservoirs to mix with water in the tub, the selection depending on a defined target temperature of water in the tub, the water from one of the hot and cold tempered reservoirs driving a temperature of water in the tub asymptotically to the target temperature, the one or more processors further receiving closed loop feedback from the first temperature sensor in the tub to shut off operation of the selected one of the first or second sets of one or more pumps when the first temperature sensor in the tub indicates to the one or more processors that the target temperature in the tub has been achieved.

A system, comprising:

• a tub, the tub comprising an exit port at or adjacent to a bottom of the tub;
• a hot tempered reservoir storing water at a first temperature;
• a cold tempered reservoir storing water at a second temperature lower than the first temperature;
• a catch reservoir for receiving water evacuated from the tub through the exit port;
• pipes connecting the hot and cold tempered reservoirs to the tub to introduce the water into the tub over top sides of the tub;
• a set of one or more pumps for pumping water from the hot and cold tempered reservoirs to the tub;
• a negative pressure container connected to the exit port for pulling water out of the tub through the exit port and the negative pressure container when the negative pressure container is opened to the tub;
• wherein the system is configured to change a temperature of water in the tub from a current temperature to a target temperature by pumping water from one of the hot and cold tempered reservoirs into the tub over the top sides of the tub and by pumping water out of the tub through the exit port;
• and
• wherein the system is further configured to stop the pumping of water into and out of the tub when water in the tub reaches the target temperature.

A system comprising a tub, a hot tempered reservoir with hot water, a cold tempered reservoir with cold water and pumps for pumping hot and cold water to the tub from the hot and cold tempered reservoirs, the system further comprising:

• a memory storing an application program;

• provide a graphical user interface configured to receive a starting temperature of water in an immersive tub contrast therapy session;
• receive, via the graphical user interface, a first temperature cycle for the contrast therapy session comprising a first target temperature, a first dwell time at the first target temperature, a second target temperature different than the first target temperature, and a second dwell time at the second target temperature;
• receive, via the graphical user interface, at least one second temperature cycle for the contrast therapy session comprising a third target temperature, a third dwell time at the third target temperature, a fourth target temperature different than the third target temperature, and a fourth dwell time at the fourth target temperature;
• control the pumps to turn on one or more of the pumps to pump water from the hot and cold tempered reservoirs into the tub at different times to achieve the first, second, third and fourth target temperatures in the tub;
• and
• control the pumps to turn off the one or more pumps upon achieving the first, second, third and fourth target temperatures.

An ecosystem comprising a tub, a hot tempered reservoir with hot water, a cold tempered reservoir with cold water and pumps for pumping hot and cold water to the tub from the hot and cold tempered reservoirs, the system further comprising:
