Portable unit for treating chronic pain
A portable pain treatment unit includes: a first pulse generator configured to deliver pulses in a frequency range typical for interferential treatment; a second pulse generator configured to deliver pulses in the frequency range for transcutaneous electrical nerve stimulator (TENS) treatment; electrodes operatively connected with the first and second pulse generators that are configured for application to a treatment area; and a power source operatively connected to the first and second pulse generators. A device of this configuration enables the patient to receive either IF or TENS treatment at a location of his/her choosing rather than being forced to receive IF treatment in a clinical setting.
1. A portable pain treatment unit, comprising:
a first pulse generator configured to deliver pulses in a frequency range typical for interferential treatment;
a second pulse generator configured to deliver pulses in the frequency range for transcutaneous electrical nerve stimulator (TENS) treatment;
electrodes operatively connected with the first and second pulse generators that are configured for application to a treatment area; and
a power source operatively connected to the first and second pulse generators;
wherein the unit is configured such that the first pulse generator and the second pulse generator deliver pulses separately and independently of each other.
2. The treatment unit defined in claim 1 , wherein the second pulse generator is configured to provide a pulse width of at least 300 microseconds.
3. The treatment unit defined in claim 1 , wherein the power source comprises a nickel metal hydride battery.
4. The treatment unit defined in claim 3 , wherein the battery is a 9-volt battery.
5. The treatment unit defined in claim 1 , wherein the unit comprises two electrodes.
6. The treatment unit defined in claim 1 , wherein the first pulse generator is configured to deliver pulses in the frequency range between about 3,900 and 5,250 Hz per channel.
7. The treatment unit defined in claim 1 , wherein the second pulse generator is configured to deliver pulses in the frequency range between about 0.5 and 300 Hz.
8. The treatment unit defined in claim 1 , further comprising a switch configured to alternatively activate the first pulse generator or the second pulse generator.
