Embodiment Construction

[0007] Specific embodiments of the present invention are described with reference to the above drawings.

[0008] Depend on figure 1 It can be seen from the figure that this multi-band music electrotherapy instrument includes a signal source 10, a signal processing circuit 20 for processing the output signal of the signal source 10, and an output terminal 30 for outputting the signal processed by the signal processing circuit 20. The signal processing circuit The signal input terminal of 20 is connected in series with a signal amplification module U 3 , the signal amplification module U 3 Pins 1, 2, 3, and 8 are connected to the signal source 10, pins 4 and 6 are grounded, pin 5 is connected to power input, and pin 7 outputs signals. The fifth pin passes through the capacitor C 20 6th foot. Through the signal amplification module U 3 To adjust the output intensity of the treatment and increase the output range, so that the product can not only be used on needles, but also ...

Abstract

The invention provides a multi-band music electrotherapy instrument which comprises a signal source (10), a signal processing circuit (20) and an output end (30), wherein the signal processing circuit (20) is used for processing a signal output by the signal source (10), the output end (30) is used for outputting the signal processed by the signal processing circuit (20), a signal input end of the signal processing circuit (20) is connected with a signal amplifying module U3 in series and an output signal of the signal amplifying module U3 is output after being filtered by a primary filter circuit (21) and a band-pass filter circuit (22). According to the invention, Researches on music signal frequencies in a music therapy show that different music frequencies have different therapeutic effects on a human body, frequencies at effective therapeutic bands in music are maintained and harmonic wave and a high-frequency part in the music are filtered out through multiple-level filtering. A band-pass filter is adopted to perform high-power amplification on an intermediate-frequency signal and low-power amplification on a low-frequency signal so that a patient feels very comfortable in a therapy process and the therapeutic effect can be ensured.

Description

technical field [0001] The invention relates to medical equipment, in particular to a music therapy instrument for electrotherapy. Background technique [0002] At present, the electrotherapy instrument generally includes the following forms, among which the audio electrotherapy machine is a simple equal-amplitude intermediate frequency sinusoidal current therapeutic instrument. It is a method of treatment by applying a medium-frequency sinusoidal alternating current with a frequency in the audio frequency range. Application frequency 1000Hz-4000Hz. Some therapeutic instruments also have audio therapy methods, but most of them are equal-amplitude intermediate-frequency square wave currents, which are not the waveforms used by audio electrotherapy machines in the true sense. Pulse electroacupuncture refers to an acupuncture technique that uses various pulse generators (pulse electroacupuncture instruments) to input pulse currents to human acupoints on the basis of filiform ...
