Abstract

Disclosed herein is a system, apparatus and method directed to patient temperature control. The system can include a control module configured to provide fluid that is heated or cooled, a heating and cooling system configured to couple with the control module and receive the fluid, and a temperature sensor coupled to the control module, the temperature sensor configured to measure a body temperature of a patient and provide signals to the control module that indicate the body temperature. The system can include a neurostimulation device coupled to the control module to provide neurostimulation to the patient. The control module can include logic, stored on non-transitory, computer-readable medium that, when executed by one or more processors, causes performance of operations including generation and transmission of first instructions to the neurostimulation device causing initiation of a first neurostimulation procedure.

First claim

1 . A patient temperature control system, comprising:
a control module configured to provide fluid that is heated or cooled, wherein the control module includes a circulating pump; a heating and cooling system configured to couple with the control module and receive the fluid, wherein circulating pump is configured to circulating the fluid through the heating and cooling system; a temperature sensor coupled to the control module, the temperature sensor configured to measure a body temperature of a patient and provide signals to the control module that indicate the body temperature; and a neurostimulation device coupled to the control module and configured to provide neurostimulation to the patient, wherein the control module includes logic, stored on non-transitory, computer-readable medium that, when executed by one or more processors, causes performance of operations including generation and transmission of first instructions to the neurostimulation device causing initiation of a first neurostimulation procedure.

2 . The system of claim 1 , wherein the control module includes a heat exchange system for heating or cooling the fluid.

3 . The system of claim 1 , wherein the logic, when executed by the one or more processors, causes performance of further operations including:
receiving the signals indicating the body temperature; analyzing the body temperature to determine whether a temperature of the fluid is to be adjusted; and providing second instructions to the heat exchange system indicating whether the fluid is to be heated, cooled, or maintained at a current temperature.

4 . The system of claim 1 , wherein the control module further includes a fluid reservoir that is maintained at substantially atmospheric pressure.

5 . The system of claim 1 , further comprising a motion sensor device configured to measure an amount of motion of the patient indicating a level of shiver.

6 . The system of claim 1 , wherein the heating and cooling system includes one or more contact pads configured to directly or indirect contact the patient and receive the fluid.

7 . The system of claim 1 , wherein the neurostimulation device includes an external electrode and an internal electrode, and is configured to provide deep brain stimulation.

8 . The system of claim 1 , wherein the neurostimulation device includes an external electrode and an internal electrode placed within the patient's skull, and is configured to provide deep brain stimulation.

9 . The system of claim 1 , wherein the neurostimulation device includes at least a first set of electrodes for placement on the patient's skill, the first set of electrodes including an emitter and a receiver each configured to receive power via a power supply device, wherein the neurostimulation device is configured to provide noninvasive brain stimulation.

10 . The system of claim 1 , wherein the neurostimulation device is a wrist-worn device.

11 . The system of claim 1 , wherein the neurostimulation is configured to target the hypothalamus to control thermoregulation of the patient's body and prevent or reduce patient shiver.

12 . A method of providing targeted temperature management and neurostimulation, the method comprising
providing a targeted temperature management (TTM) procedure to a patient by circulating cooled fluid through a heating and cooling system directly or indirectly in contact with the patient; obtaining a measurement indicating an amount of shiver by a body of the patient; determining, based at least in part on the measurement indicating the amount of shiver, a neurostimulation procedure to be initiated on the patient; and providing the neurostimulation procedure to the patient.

13 . The method of claim 12 , wherein the TTM procedure is provided by a combination of a control module configured to provide the cooled fluid and a circulating pump configured to circulate the cooled fluid through the heating and cooling system.

14 . The method of claim 13 , wherein the control module receives a measurement of a body temperature of the patient from a temperature sensor.

15 . The method of claim 13 , wherein the control module includes logic, stored on non-transitory, computer-readable medium that, when executed by one or more processors, causes performance of operations including generation and transmission of first instructions to a neurostimulation device causing the providing of the neurostimulation procedure to the patient.

16 . The method of claim 12 , wherein the neurostimulation device includes an external electrode and an internal electrode placed within the patient's skull, and is configured to provide deep brain stimulation.

17 . The method of claim 12 , wherein the neurostimulation device includes at least a first set of electrodes for placement on the patient's skill, the first set of electrodes including an emitter and a receiver each configured to receive power via a power supply device, wherein the neurostimulation device is configured to provide noninvasive brain stimulation.

18 . The method of claim 12 , wherein the neurostimulation device is a wrist-worn device.

19 . The method of claim 12 , wherein the neurostimulation procedure is configured to target the hypothalamus to control thermoregulation of the patient's body and prevent or reduce patient shiver.

20 . The method of claim 12 , wherein the control module further includes a fluid reservoir that is maintained at substantially atmospheric pressure.
