The utility model does not need to press a switch intermittently for discharging when used, and the discharge cycle is stable. A treatment can be reminded to stop by an audible alarm. The utility model has the advantages of small size and portability.
Description
This utility model relates to treats the instrument that hypertension uses and belongs to Medical Instruments.
Hypertension has become one of healthy three big diseases of harm humans, and the instrument of therefore treating this disease has more kind, but nothing more than adopting electricity, magnetic stimulating acupoint to reach the purpose of treatment.Disclose a kind of high blood pressure therapeutic equipment in CN88207428.8, the charging and discharging circuit that it is made up of resistance, switch and electric capacity bleeds off the high bioelectric potential of hyperpietic's body surface relevant acupoints and progressively returns to normal current potential, reaches the purpose of treatment.But its troublesome poeration is embodied in following 2 points particularly: must artificial intermittently Push switch, make its discharge and since the time intermittently difficulty be controlled to unanimity, therefore the cycle of discharge changes, and curative effect is had certain influence; The length of treatment time needs oneself to see clock and watch control.
The purpose of this utility model be to provide discharge and recharge a kind of automatic intermittence, treatment time timing alarm hypertension instrument.
Task of the present utility model is that following mode realizes: the outfan of DC power supply is received low-frequency oscillation drive circuit and adjustable timer circuit respectively, the output termination charging and discharging circuit of low-frequency oscillation drive circuit, the outfan receiving electrode of charging and discharging circuit, as shown in Figure 1.Specifically, low-frequency oscillation driver is formed RC circuit (time circuit) by resistance, electric capacity and audion and is connected in series audion, a coil that plays on-off action and forms.Adjustable timer circuit is made up of resistance, electric capacity and audion that RC circuit (time circuit) is connected in series controllable silicon, the news Chinese percussion instrument is formed.
Because this utility model has increased low-frequency oscillation drive circuit and adjustable timer circuit, needn't be artificially when using this utility model Push switch intermittently, promptly by regular the discharging and recharging of low-frequency oscillation driver drives charging and discharging circuit, therefore the cycle of discharge is relatively stable, in 10～15 minutes, setting in advance as required of treatment time, control by adjustable timer circuit, remind with audible alarm to the time to stop treatment, needn't oneself see clock and watch control.This instrument volume is little, can carry.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
