Abstract

The present invention relates to an apparatus for alleviating a transcutaneous pain using electrical stimulation, which comprises: an output unit for generating a packet waveform in an amplitude and frequency range corresponding to a random number value randomly generated within a preset range; an electrode cable having one end thereof connected to a cable terminal provided in a main body, and applying an output value applied from the output unit to a pair of electrodes connected to the other end thereof; and a pair of electrodes for applying an output of the output unit to an affected area by being connected to a snap terminal provided at an end of the electrode cable. The output unit includes: a cable terminal for connection with the electrode cable; a random number generating module for generating a random number value within a preset range; and an output module for generating the packet waveform in the amplitude and frequency range corresponding to the random number value. According to the present invention, the packet waveform in the amplitude and frequency range varied in accordance with an output value of a random number generator is applied to an affected area. In addition, when an ADC value of an output terminal exceeds a preset reference, it is determined that the electrodes are detached from the affected area to stop the output of the packet waveform and to output an open error. In addition, when the ADC value of the output terminal is less than a preset reference, a short error is output since the electrodes are attached to each other. The connector is provided at a front end of the electrodes connected to equipment through the cable, thereby disturbing a pain transfer of a central nervous system not to recognize an intractable chronic pain, a cancerous pain, an extreme pain after surgery, a neuralgia or muscular pain. Furthermore, a short-circuit between the electrodes and the affected area can be immediately checked, and a problem of replacing the cable due to detachment of the electrodes in case of operating a pain treatment apparatus for a long time is solved, and only the connector and the electrodes can be separately replaced in case of electrode detachment, such that maintenance is easy.

Description

Percutaneous pain relief device using electric stimulation {Apparatus for relieving pain using electric stimulation}

The present invention relates to a percutaneous pain relieving device using electrical stimulation, and more particularly, by passing a packet waveform of amplitude and frequency range varied according to a random number generator output value to an affected part, rather than preventing or blocking pain. The present invention relates to a technique for disturbing pain transmission of the central nervous system and recognizing it as a normal signal.

In general, a device for treating pain by imparting electrical stimulation to an affected part includes a pair of electrode pads attached to a pain area, and then a packet waveform having a predetermined amplitude and frequency range (43 Hz to 52 Hz by a hexadecimal vector). It is configured to alleviate the pain by passing on to the affected area.

However, these pain treatment devices are configured to impart unnaturally strong intensity (50 mA to 150 mA) low frequency currents that are not produced by the human body to the affected area, and the pain transmission is repeated by stimulating the A-beta (tactile) nerve at a constant frequency. As a blocking principle, pain is limited to muscle pain.

However, since the pain treatment device stimulates the affected part at a constant frequency, when the affected part is exposed to the low frequency current at the corresponding frequency for a long time, the brain perceives the amplitude and the frequency, and there is no pain relief effect, and a burn or an arrhythmia may occur. There is a problem that the risk is large.

Accordingly, the present applicant transfers a packet waveform having a variable amplitude and frequency range to the affected part according to the random number generator output value, thereby preventing the pain from being blocked or blocking the pain transmission of the central nervous system and recognizing it as a normal signal. I would like to suggest.

For example, when the random number value received from the random number generation module 102b of the output module 102c matched with channel 1 is 43 Hz, the output module 102c outputs an amplitude and a packet waveform as shown in FIG. 3B. When the output module 102c matched with the random number generated from the random number generation module 102b is 50 Hz, the output module 102c outputs an amplitude and a packet waveform as shown in FIG. 3B.
