Abstract

A system is provided for a Transcutaneous Electrical Nerve or Electrical Muscle Stimulation. The system generally includes at least two electrodes carried on a single substrate adapted to be disposed in electrical contact with a body surface, and an electrical stimulation unit configured to deliver electrical pulses to muscle groups or nerve endings adjacent a body surface that is in electrical contact with the at least two electrodes. The electrical stimulation unit includes an on-board controller configured for controlling the stimulation unit to deliver electrical pulses for pain relief and/or muscle relaxation.

Claims

at least two electrodes carried on a single substrate adapted to be disposed in electrical contact with a body surface; and

an electrical stimulation unit configured to deliver electrical pulses to muscle groups or nerve endings adjacent a body surface that is in electrical contact with the at least two electrodes, the electrical stimulation unit including an on-board controller configured for controlling the stimulation unit to deliver electrical pulses for pain relief and/or muscle relaxation.

2. The system according to claim 1, wherein the electrical stimulation unit is operable at at least two intensities, and wherein the on-board controller includes an intensity selector for selecting one of the at least two intensities of operation for the electrical stimulation unit.

3. The system according to claim 2, wherein the intensity selector comprises an increase control and a decrease control for increasing and decreasing intensity, respectively.

4. The system according to claim 1, wherein the electrical stimulation unit is operable at a plurality of operating modes, each of which applies a different time-varying electrical potential to the at least two electrodes, and wherein the on-board controller includes a mode selector for selecting one of the plurality of operating modes for the electrical stimulation unit.

5. The system according to claim 1, wherein the electrical stimulation unit is operable for a selectable time period, and wherein the on-board controller includes a time selector for selecting the time period of operation for the electrical stimulation unit.

6. The system according to claim 1 further comprises an audible alarm configured to send an alert in response to at least one operating instruction.

7. The system according to claim 1, wherein the single substrate has a general butterfly shape, with first and second lobes joined at a central junction.

8. The system according to claim 7, wherein the single substrate includes at least two connectors configured for electrically connecting the at least two electrodes to the electrical stimulation unit.

9.
