A low frequency and intermediate frequency electric treatment instrument

摘要

The present invention maximizes the treatment effect by slowly or manually outputting low frequency or medium frequency current to minimize the pain of the patient due to instantaneous current inflow in order to apply direct current to the affected part according to the condition of the patient. The present invention relates to a human body reactive current applying device.;That is, in the present invention, in the low frequency and medium frequency electrotherapy device 1, an electrode 13 attached to the affected part of a patient is connected to a sensor 11 and a signal that is amplified by a signal from the sensor 11. Amplifying section 10, an A / D converting section 9 for converting the analog signal amplified by the amplifying section 10 into a digital signal, and a signal applied through the A / D converting section 9 A microcomputer 8 for receiving control and command signals; a circuit connected to the microcomputer 8; a display and control unit 7 for setting a treatment current and frequency, a setting of treatment time, and a set value; A D / A converter 1 (4), which is connected to the microcomputer 8 and converts a digital signal into an analog signal, a modulator 2 connected to the D / A converter 1 (4), and the modulator A frequency generator (1) connected in circuit with (2), a comparator (3) and an output part (6) connected in circuit with the modulator (2), and the output part (6). An output transformer 12 for connecting the current output from the circuit to the electrode 13 connected to the affected part of the patient, and between the comparator 3 and the microcomputer 8 to change the digital signal into an analog signal. Provides a low frequency and medium frequency electrotherapy device having a / A conversion unit 2 (5),;The low and medium frequency electrotherapy devices provided by the present invention can be expected to provide an excellent treatment effect because they can send a large current without pain or rejection when the patient wants to energize the current directly in the affected area as well as in the low and medium frequency electrotherapy devices. It can be.
