ABSTRACT:
TECHNICAL FIELD
The invention relates generally to transcutaneous electrical neuro-stimulation (TENS) units and this invention particularly relates to a miniaturized wireless TENS unit capable of being pre-programmed to achieve a variety of waveforms, with or without the use of a remote controller means, each with unique features capable of masking pain or promoting functional restoration in a user's body.
BACKGROUND OF THE INVENTION
TENS devices have been traditionally prescribed in the medical industry for chronic pain. While patients experiencing acute pain are prescribed anti-inflammatories and narcotic agents, the treatment of chronic pain, usually defined as unrelieved pain for at least 30 days, has usually been dealt with via TENS-related prescriptions. However, TENS devices have been shown to provide rapid and effective relief for acute pain without side effects or the possibility of addiction. TENS does not utilize anesthesia or narcosis. Patients remain awake, alert and functional, and retain the protective qualities of increased pain perception.
TENS is commonly used for acute pain management by physical therapists in comprehensive rehabilitation programs in conjunction with other treatments. TENS devices are usually large as well as being complex, expensive and require lead wires running to each electrode, making them difficult for use at home, at work or at play.
Consequently there is a need in the art for a miniaturized, wireless TENS device that can be utilized by the patient without the embarrassment of unsightly wires protruding through clothing, and that can be placed on a variety of sites on the patient's body, virtually unseen, and which can be controlled by a controller means to transmit pulses at different intensities and frequencies adaptable to the patient's particular physical malady.
Previous attempts have been made to design improved electro-therapy devices, certain features of which are generally described in U.S. Pat. No. 5,620,470 to Gliner et al.; U.S. Pat. No. 5,607,454 to Cameron et al.; U.S. Pat. No. 5,601,612 to Gliner et al.; U.S. Pat. No. 5,593,427 to Gliner et al.; U.S. Pat. No. 5,584,863 to Rauch et al.; U.S. Pat. No. 5,578,060 to Pohl et al.; U.S. Pat. No. 5,573,552 to Hansjurgens; U.S. Pat. No. 5,549,656 to Reiss; U.S. Pat. No. 5,514,165 to Malaugh et al.; U.S. Pat. No. 5,476,481 to Schöndorf; U.S. Pat. No. 5,387,231 to Sporer,; U.S. Pat. No. 5,397,338 to Grey et al.,; U.S. Pat. No. 5,374,283 to Flick,; U.S. Pat. No. 5,354,320 to Schaldach et al.; U.S. Pat. No. 5,304,207 to Stromer; U.S. Pat. No. 5,183,041 to Toriu et al.; U.S. Pat. No. 4,989,605 to Rossen; U.S. Pat. No. 4,759,368 to Spanton et al.; U.S. Pat. No. 4,699,143 to Dufresne et al.; and U.S. Pat. No. 4,398,545 to Wilson, all of which are incorporated herein by reference. However, none of these references, either alone or in combination with others, describes a miniature, wireless transcutaneous neuro stimulation device with a remote controlled configuration that has pre-programmable waveform modes and includes a unique detachable electrode-battery assembly. What is needed is a miniature, wireless TENS-related device that can easily be programmed by the user, with or without the use of a remote controller, to provide a variety of waveforms at various programmable intensities to a number of pain sites on the user's body, and which can be easily adaptable for use with splints, braces and bandages. The present invention satisfies this need.
SUMMARY OF THE INVENTION
Generally, the present invention provides a miniature wireless transcutaneous electrical neuro or muscular-stimulation unit including a housing; a plurality of electrodes attached to the housing; an electronics module located within the housing and comprising an electrical circuit which provides a biphasic or monophasic sequence of pulses to the electrodes, wherein the sequence of pulses form a plurality of pre-programmable waveforms available for specific clinical needs; means to restrict the waveforms available to those appropriate for the electrode and treatment through a series of one or more protrusions within the housing, wherein the protrusions interface with the electronics module to determine the waveform to be used; means for allowing a user to select and control specific waveforms and intensities of the waveforms; means to identify the specific waveform chosen, its intensity and its duration; and means for supplying power to the electronics module wherein the means for supplying power is integrated with the electrodes in one assembly.
In an alternate embodiment the means for supplying power to the electronics module is a plurality of batteries.
An alternate embodiment of the present invention provides that the batteries are replaceable or rechargeable.
In an alternate version, the identifying means is an LCD digital readout display.
In an alternate embodiment, the means for allowing the user to select and control specific waveforms and intensities of waveforms is through a series of input devices controlling an LCD digital readout display which allows the user to vary the intensity of the waveforms.
In an alternate form, the means for allowing the user to select and control specific waveforms and intensities of waveforms comprises a removable tether having a first and second end wherein the first end is affixed to the electrode-battery assembly and the second end is affixed to the miniature wireless transcutaneous electrical neuro or muscular-stimulation unit.
In an alternate embodiment, the electrodes are disposable.
An alternate embodiment of the present invention provides that the electronics module be disposable.
In an alternate embodiment, the electronics module is detachable and is able to be snapped into and out of each miniature wireless transcutaneous electrical neuro or muscular-stimulation unit.
In an alternate form, the plurality of electrodes have varying shapes and sizes and can be affixed directly to a site or other area requiring electrical neuro or muscular-stimulation anywhere on the user's body, the electrodes are positioned at a specified distance from the electronics module wherein the electrodes are swivel or fixed electrodes which allow for optimal placement of the electrodes at the pain site or the area requiring electrical neuro or muscular-stimulation.
In an alternate embodiment, the plurality of waveforms are comprised of but not limited to, a conventional-low mode and a conventional-high mode, a modulation-low mode and a modulation-high mode, an acupuncture-like low mode and an acupuncture-like high mode, a microcurrent mode, a burst mode and a cycling mode wherein the conventional-low mode supplies to the plurality of electrodes biphasic or monophasic pulses of about 0-60 milliamperes at a frequency of about 100 Hz having a pulse width of about 75 microseconds, the conventional-high mode supplies to the electrodes biphasic or monophasic pulses of about 0-100 milliamperes at a frequency of about 100 Hz having a pulse width of about 125 microseconds, the modulation-low mode supplies to the electrodes biphasic or monophasic pulses of about 0-60 milliamperes at a frequency of about 50-100 Hz having a pulse width of about 75-100 microseconds, the modulation-high mode supplies to the electrodes biphasic or monophasic pulses of about 0-100 milliamperes at a frequency of about 75-100 Hz having a pulse width of about 100-125 microseconds, the acupuncture-like low mode supplies to the plurality of electrodes biphasic pulses of about 0-60 milliamperes at a frequency of about 1 Hz having a pulse width of about 75 microseconds, the acupuncture-like high mode supplies to the electrodes biphasic pulses of about 0-100 milliamperes at a frequency of about 2 Hz having a pulse width of about 125 microseconds, the microcurrent mode supplies to the plurality of electrodes biphasic pulse of about 0-100 microamperes at a frequency of about 0.3-100 Hz, the burst mode supplies to the plurality of electrodes biphasic or monophasic pulses of about 0-100 milliamperes at a frequency
