Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below this utility model embodiment is described in further detail.
Referring to Fig. 1, a kind of skin surface electrical stimulation therapeutic instrument comprises: voltage-regulating circuit 1, electric pulse generative circuit 2, stimulating electrode 3, current measurement circuit 5 and display circuit 6, wherein, voltage-regulating circuit 1 connects electric pulse generative circuit 2 and stimulating electrode 3 successively, the outfan of stimulating electrode 3 is connected with the input of current measurement circuit 5, and the outfan of stimulating electrode 3 acts on skin surface 4 simultaneously; The outfan of current measurement circuit 5 connects respectively voltage-regulating circuit 1 and display circuit 6; Voltage signal after voltage-regulating circuit 1 output is adjusted is to electric pulse generative circuit 2, and electric pulse generative circuit 2 receiver voltage signals output stimulate electric pulse to stimulating electrode 3.Current measurement circuit 5 is measured the electric current of human body and is transferred to voltage-regulating circuit 1, adjusts the voltage of voltage-regulating circuit 1.
When specific implementation, this display circuit 6 is electrically connected current measurement circuit 5, can more clearly show the electric current of subjects's body surface, timely the input voltage in voltage-regulating circuit 1 is adjusted, and avoids the injury to subjects.When practical application, this display circuit 6 can be: the liquid crystal displays such as LED, LCD.
When actual use, can be by the voltage magnitude of manual setting stimulating electrode 3.Referring to Fig. 2, the principle of voltage-regulating circuit 1 is: by changing, the ADJ of power supply chip holds and the resistance of GND end is recently realized voltage adjustment.
This utility model has adopted digital regulation resistance, and digital regulation resistance can pass through Digital Signals.In reality test, find that digital regulation resistance can not be used as simple variableimpedance and use, but be applicable to dividing potential drop.Therefore in voltage-regulating circuit 1, between the ADJ of power supply voltage stabilizing chip REG LR12 end and outfan, voltage remains on this characteristic of 1.2V always, as long as the voltage of ADJ end is adjusted, just can adjust the voltage of outfan, thereby realize automatic Regulation.Here digital regulation resistance is being brought into play the effect of potentiometer.
Owing to adopting the digital regulation resistance of MAX series in this electric stimulation therapeutic apparatus, its the highest withstand voltage is 30V, therefore as shown in Figure 2, the first switch S 2 that introducing is connected in parallel, second switch S3 and the 3rd switch S 4, by suitably switching this three switches, just can realize and both ensure that output voltage reached 88V, also can ensure the withstand voltage 30V of being no more than of the digital regulation resistance of MAX series.
Because output waveform can be the square wave (being not limited only to square wave) of high frequency, therefore contain very high high order composition, thereby make the current value detecting there is very large noise, in order to reach noise reduction and correctly to obtain current value, detecting between current output terminal and the AD converter of controller, add low pass filter LPT.
