AI Technical Summary
Benefits of technology
The device ensures consistent and effective pain relief by dynamically adjusting stimulation parameters to match changing circadian fluctuations, providing optimal therapeutic intensity throughout the day and night, enhancing user comfort and therapeutic efficacy.
Problems solved by technology
Intensities below the threshold of sensation are not clinically effective.
Therefore, a major limitation of current TENS devices is that it may be difficult for many users to determine an appropriate therapeutic stimulation intensity.
As a result, the user will either require substantial support from medical staff or they may fail to get pain relief due to an inadequate stimulation level.
The persistent nature of chronic pain and the convenience of “wear-and-forget” TENS technology may lead some users to wear the TENS device daily for an extended period of time.
Therefore, a single time-invariant TENS dose may not provide consistent pain relief throughout the day for a TENS user.

Embodiment Construction
[0036]The present invention comprises the provision and use of a novel TENS device which comprises a stimulator designed to be placed on a user's upper calf (or other anatomical location) and a pre-configured electrode array designed to provide electrical stimulation to at least one nerve disposed in the user's upper calf (or other anatomical location). A key feature of the present invention is that the novel TENS device automatically adjusts stimulation parameters according to the time of day.
[0037]More particularly, and looking now at FIG. 1, there is shown a novel TENS device 100 formed in accordance with the present invention, with novel TENS device 100 being shown worn on a user's upper calf 140. A user may wear TENS device 100 on one leg or on both legs (either one at a time or simultaneously) or a user may wear a TENS device 100 on another area of the body, separate from, or in addition to, a TENS device worn on one leg (or both legs) of the user.
[0038]Looking next at FIG. 2,...

Apparatus for transcutaneous electrical nerve stimulation in a user, the apparatus comprising: stimulation means for electrically stimulating at least one nerve with at least one stimulation pulse; control means connected to the stimulation means for controlling at least one characteristic of the at least one stimulation pulse; and modulating means connected to the control means for modulating the at least one characteristic of the at least one stimulation pulse according to the time of day.
Description
REFERENCE TO PENDING PRIOR PATENT APPLICATION[0001]This patent application claims benefit of pending prior U.S. Provisional Patent Application Ser. No. 62 / 361,698, filed Jul. 13, 2016 by NeuroMetrix, Inc. and Shai N. Gozani for APPARATUS AND METHOD FOR AUTOMATED COMPENSATION OF TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION FOR CIRCADIAN RHYTHMS (Attorney's Docket No. NEURO-83 PROV), which patent application is hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention generally relates to Transcutaneous Electrical Nerve Stimulation (TENS) devices that deliver electrical currents across the intact skin of a user in order to provide symptomatic relief of chronic pain, and more particularly to TENS devices configured for automated compensation for circadian rhythms and other temporal variations in the user's physiology.BACKGROUND OF THE INVENTION[0003]Transcutaneous electrical nerve stimulation (TENS) is the delivery of electricity (i.e., electrical stimulation) a...
