Systems and methods for providing temperature-controlled therapy
View Patent ↗Systems and methods provide air or gas-based temperature-controlled medical devices. The systems and methods may be applied to provide therapy to a patient suffering orthopedic or other injuries. Air or other gas is temperature-controlled and adjusted to meet a patient's physical needs and delivered the patient therapy site through a temperature regulated system including a therapeutic orthopedic wrap. Feedback mechanisms allow the caregiver or the patient to adjust the temperature of the gas. Other fluids may also be used. The systems and methods permit use of electrotherapy for enhanced therapy and injury recovery.
1. A system for delivering a temperature-controlled gas to a therapy site comprising:
a gas temperature regulator;
a gas intake port;
a first line configured to supply heated gas from the temperature regulator;
a second line configured to supply cooled gas from the temperature regulator;
a first valve configured to receive the heated gas from the first line, receive the cooled gas from the second line, and output a mixture of the heated gas and the cooled gas to a therapy pad at a controlled temperature; and
the therapy pad, comprising:
an insulating layer,
a flow channel disposed behind and configured to distribute the mixture of the heated gas and the cooled gas to an inner face of the therapy pad,
a lower frame configured to mate with the therapy site,
a mesh layer disposed between the insulating layer and the lower frame and comprising a plurality of undulations configured to deliver the mixture of the heated gas and the cooled gas to the therapy site within the lower frame, and
at least one electrostimulation electrode embedded within the inner face of the therapy pad, the at least one electrostimulation electrode having a first surface configured to make direct electrical contact with the therapy site and a second surface opposite the first surface configured to make direct physical contact with the mixture of the heated gas and the cooled gas within the flow channel.
2. The system of claim 1 , wherein the gas intake port is a manifold in communication with ambient air.
3. The system of claim 1 , wherein the gas intake port is in communication with stored or compressed gas.
4. The system of claim 1 , wherein the gas temperature regulator comprises a cooling component and a heating component.
5. The system of claim 4 , wherein the heating component and cooling component are disposed within a single housing.
6. The system of claim 1 , wherein the gas temperature regulator is a Peltier device.
7. The system of claim 1 , further comprising a temperature sensor configured to sense a temperature of one or both of:
the mixture of the heated gas and the cooled gas; or
the therapy site.
8. The system of claim 7 , wherein the gas temperature regulator further comprises a controller configured to receive a signal from the temperature sensor and trigger an alarm when the signal indicates a temperature satisfying a predetermined temperature threshold.
9. The system of claim 1 , comprising a temperature maintenance pack.
