An electronic device and method are disclosed for effecting both nerve fiber and body tissue stimulation. Nerve fiber stimulation is primarily effected by application of pulses, and preferably by application of biphasic pulse pairs the pulses of which are spaced from one another in a pattern such that nerve fiber stimulation applied through plural active electrodes enhances pain suppression. Body tissue treatment is primarily effected by application of a net DC charge, and preferably by application of biphasic pulses that includes a greater number of either negative or positive pulses so that a net DC charge results. The DC charge level is maintained at a substantially constant selected value regardless of pulse variations within established broad limits, and the DC charge level is adjustable between operational modes, as needed.

Combined nerve fiber and body tissue stimulation apparatus and method

Transcutaneous nerve stimulator

An electronic stimulating device is disclosed, with the stimulating device particularly illustrated being a transcutaneous nerve stimulating (TENS) device for effecting suppression of pain by nerve fiber stimulation. Biphasic constant current output pulses are applied to a user through electrode pairs noninvasively positioned at the skin of the user. Microprocessor generated control pulses control generation of the biphasic output pulses at a biphasic output stage associated with each electrode pair, and the generated biphasic output pulses are capacitively coupled from each output stage which also includes a bleeder network for effecting capacitor discharge. Stimulation may be continuously applied at a level selected by the user or may be applied in timed varying intensities the maximum level of which is selectable, and displays of intensity and sensed faults, including low battery voltage, are also provided.

Microprocessor controlled electronic stimulating device having biphasic

A device and method are disclosed for effecting timed treatment of varying intensity in an electronic stimulating device, with the stimulating device particularly illustrated being a transcutaneous nerve stimulating (TENS) device for effecting suppression of pain by nerve fiber stimulation. Biphasic constant current output pulses are applied to a user through electrode pairs noninvasively positioned at the skin of the user. Microprocessor generated control pulses control generation of the biphasic output pulses at a biphasic output stage associated with each electrode pair. Stimulation may be continuously applied at a level selected by the user or may be applied in timed varying intensities the maximum level of which is selectable, with a display also being provided of selected and applied intensity levels.

Electronic stimulating device having timed treatment of varying

An electronic stimulating device for wound healing and, more particularly, for enhancing healing of soft tissue wounds. The device includes a plurality of signal generators for generating output pulses suitable for enhancing healing of soft tissue wounds by application of the output pulses through electrodes to the soft tissue to be healed. Two pairs of active electrodes are included along with a pair of return electrodes. Control signals from a pulse generator control generation of the output pulses and a digital timer is included for causing treatmet for a predetermined period of time. The intensity, polarity, and rate of the output pulses can be varied by rotation of control knobs on the front panel of the device or, alternately, can be effected by a series of switches located on the front panel of the device, with varying intensities of output being indicated by brightness varying light emitting diodes.
