Abstract
A heating pad assembly includes a flexible heating pad having a flexible substrate forming a plurality of deflectable tabs and one or more electrically conductive heating traces routed through the plurality of deflectable tabs and configured to radiate heat therefrom in response to electrical current flowing through the one or more heating traces.
Claims20
A heating pad assembly comprising:
- a flexible heating pad comprising:
- a flexible substrate having a longitudinal dimension and a transverse dimension that is perpendicular to the longitudinal dimension, the flexible substrate forming a plurality of deflectable tabs including:
- first and second distal corner tabs each associated with both distal end and side portions of the flexible substrate, the first and second distal corner tabs being separated by a distal longitudinal slit that is positioned at a widthwise center of the flexible substrate and aligned with the longitudinal dimension;
- a first set of side tabs on a first side of the widthwise center of the flexible substrate, the first set of side tabs being separated by a first set of transverse slits that terminate on the first side and run parallel with the transverse dimension;
- and
- a second set of side tabs on a second side of the widthwise center of the flexible substrate, the second set of side tabs being separated by a second set of transverse slits that terminate on the second side and run parallel with the transverse dimension;
- and
- one or more electrically conductive heating traces routed through the plurality of deflectable tabs and configured to radiate heat therefrom in response to electrical current flowing through the one or more electrically conductive heating traces, the one or more electrically conductive heating traces crossing over both the widthwise center and a lengthwise center of the flexible substrate.

A heating pad assembly comprising:
- a popliteal fossa heating pad comprising:
- a first flexible substrate having a first length in a first longitudinal dimension and a first width in a first transverse dimension perpendicular to the first longitudinal dimension, the first flexible substrate including a first set plurality of deflectable side tabs defined by transverse slits in the first flexible substrate that run parallel with the first transverse dimension;
- and
- one or more electrically conductive first heating traces configured to radiate heat in response to electrical current flowing therethrough;
- wherein the first set of side tabs are matched in length to define straight side profiles of the first flexible substrate;
- and
- a foot heating pad coupled to the popliteal fossa heating pad via a coupling dimensioned to span between a popliteal fossa and foot of a patient, the foot heating pad comprising:
- a second flexible substrate having a second length in a second longitudinal dimension, the second length being shorter than the first length, the second flexible substrate including a second set of deflectable side tabs defined by transverse slits in the second flexible substrate that run parallel with a second transverse dimension perpendicular to the second longitudinal dimension;
- and
- one or more electrically conductive second heating traces configured to radiate heat in response to electrical current flowing therethrough;
- wherein the second set of side tabs are graduated in length to define tapered side profiles of the second flexible substrate.
