Transcutaneous electrical nerve stimulator with hot or cold thermal application
View Patent ↗A Transcutaneous Electrical Nerve Stimulator (TENS) and electrode pad that is capable simultaneously of delivering hot or cold thermal therapy for the relief of pain.
1. A transcutaneous electrical nerve stimulator device comprising:
a housing comprised of a solid thermal reservoir body fabricated from a soft solid polymer which comprises a polymer filled with high thermal mass particles;
a signal generating power supply embedded within the housing; and
at least two opposing electrodes embedded within the housing with at least a portion of said electrodes exposed through an outer surface of said housing such that they are capable of contacting a user's skin.
2. The device of claim 1 wherein the soft solid polymer is an oil gel.
3. The device of claim 1 wherein the soft solid polymer comprises an elastomer and the high thermal mass particles comprise metal oxide fillers.
4. The device of claim 1 wherein the soft solid polymer comprises an elastomer and the high thermal mass particles comprise metal fillers.
5. The device of claim 1 wherein circuitry for control inputs, power, and signal outputs is embedded in the housing.
6. The device of claim 5 wherein the control inputs are operated by external remote circuitry.
7. The device of claim 1 wherein external circuitry is used for control inputs and signal generation.
8. The device of claim 1 further comprising an external lead connected to the opposing electrodes.
