Apparatus and method for relieving pain using transcutaneous electrical nerve stimulation
Apparatus for transcutaneous electrical nerve stimulation in humans, the apparatus comprising: a housing; stimulation means mounted within the housing for electrically stimulating nerves; an electrode array releasably mounted to the housing and connectable to the stimulation means, the electrode array comprising a plurality of electrodes for electrical stimulation of nerves; control means mounted to the housing and electrically connected to the stimulation means for controlling at least one characteristic of the stimulation means; monitoring means mounted to the housing and electrically connected to the stimulation means for monitoring at least one characteristic of the stimulation means; user interface means mounted to the housing and electrically connected to the control means for controlling the stimulation means; display means mounted to the housing and electrically connected to the control means and the monitoring means for displaying the status of the stimulations means; and a strap attached to the housing; wherein the strap is configured to hold the housing, stimulation means and electrode array at a specific anatomical location to treat pain.
1. Apparatus for applying transcutaneous electrical nerve stimulation (TENS) therapy to a human, the apparatus comprising:
a housing;
an electrical stimulator mounted to the housing for generating electrical pulses of the type useful in TENS therapy;
an electrode array mountable to the housing and connectable to the electrical stimulator, the electrode array comprising a plurality of electrodes for applying the electrical pulses to a human so as to apply TENS therapy to the human;
at least one accelerometer mounted to the housing and configured to detect the orientation of the housing and, depending upon the detected orientation of the housing, modify operation of the electrical stimulator; and
a strap attached to the housing, wherein the strap is configured to hold the housing, the electrical stimulator and the electrode array at a specific anatomical location on a limb of a human so as to apply TENS therapy.
2. Apparatus according to claim 1 wherein the electrical pulses are current regulated.
3. Apparatus according to claim 1 wherein modifying the operation of the electrical stimulator comprises immediately stopping stimulation.
4. Apparatus according to claim 1 wherein modifying the operation of said electrical stimulator is to add an offset intensity to the present stimulation intensity.
5. Apparatus according to claim 1 wherein modifying the operation of said electrical stimulator includes changing stimulation intensity.
6. Apparatus according to claim 1 wherein modifying the operation of said electrical stimulator includes changing the duration of the stimulation session.
