Abstract
The utility model relates to a recorder attached with an electrotherapy apparatus, which can carry out electrotherapy by making use of the output electrical signals of the recorder. The utility model can replace special electrotherapy equipment, such as intermediate frequency sinusoidal electrotherapy apparatus, sinusoidal modulation electrotherapy apparatus, etc. The utility model is composed of a tape recorded with electrotherapy signals, an impedance matching device which can match the output signals of the recorder with the impedance characteristic of a human body, and an electrode acted on the human body. The utility model has the advantages of small volume and portability, is suitable for families, and can also be used for massage, hairdressing, etc.
Description
This utility model belongs to a kind of simple and easy, multipurpose audio frequency electrotherapy device.
Carried out audio frequency electrotherapy in the past, all adopted instrument, as intermediate frequency sinusoidal therapy instrument, Sine Modulated electric therapeutic instrument etc.Apparatus structure complexity, volume heaviness, cost an arm and a leg, and function singleness, only be suitable for special medical institutions' equipment, use.General physical therapy needs the longer course of treatment again, and patient must regularly go to hospital to receive treatment, and is not too convenient.This utility model is developed in order to change this situation.
Of the present utility model being characterised in that: various electrotherapy signals are recorded on the tape, utilize common recorder output electrotherapy signal, human body is carried out electrotherapy.
This utility model comprises following components:
(1) record has the tape of electrotherapy signal;
(2) impedance-matching device that impedance of recorder output signal and human body impedance characteristic are complementary;
(3) act on the electrode of human body.
Electrotherapy signal on the tape can be recorded as required flexibly, as intermediate frequency sinusoidal signal, sinusoidal modulation signal etc.Also can on a box tape, record two or more electrotherapy signals.
The impedance of general recorder output signal is 4 Europe or 8 Europe, and human body impedance is generally more than 1000 Europe, thereby can not be directly used in human body electrotherapy, needs an impedance-matching device.The easiest, be to utilize linear transformer to realize the output signal impedance of recorder and human body impedance characteristic are complementary.In addition, in order to adapt to the needs of human body different parts, secondary group of transformator can or connect potentiometer etc. to regulate different output impedance with centre cap.
Act on the electrode of human body, can adopt existing various electrotherapy electrodes, comprise the electrode of purpose (as massage, the beauty treatment etc.) that are used to keep healthy.
This electrotherapeutic apparatus can utilize common recorder to play the tape that record has electrotherapy signal in use, and electrotherapy signal is drawn by earphone jack, through impedance-matching device, acts on human body by electrode, carries out electrotherapy.Signal stimulus intensity can be regulated by volume potentiometer.
Impedance-matching device of the present utility model also can directly be installed in recorder the inside, makes the recorder of production directly have electrotherapeutic function.
Because this utility model utilizes common recorder, an additional easy device, promptly practicable electrotherapy.The attachment device volume is little, simple in structure, with low cost, the electrotherapy of practicable multiple unlike signal, and can carry, being particularly suitable for family and small-sized medical station uses, for special medical institutions,, also can replace part heaviness, expensive electric therapeutic instrument as psyciotherapy room of hospital etc.In addition, except that the treatment purpose, also can be used for common health care purpose,, also can be used for journey, sports tournament allaying tiredness, as long as use corresponding electrode instead as massage, beauty treatment etc.Its advantage is very significant.
Claims (5)
1, a kind of electrotherapeutic apparatus is characterized in that: electrotherapy signal is recorded on the tape, utilizes recorder output electrotherapy signal.
2, by the described electrotherapeutic apparatus of claim 1, it is characterized in that: form by tape, the impedance-matching device of electrotherapy signal and the electrode that acts on human body by record.
3, by the described electrotherapeutic apparatus of claim 2, it is characterized in that: described impedance-matching device is a linear transformer.
4, by the described electrotherapeutic apparatus of claim 3, it is characterized in that: described linear transformer secondary windings has centre cap, scalable output impedance.
