Description

A kind of hypertension instrument

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 must artificial intermittently Push switch, makes 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 electrode that connects from instrument during use, another need take on being clipped in ear, and patient's activity is restricted; The duty of instrument can't be known.

The purpose of this utility model be to provide that a kind of automatic control intermittently discharges and recharges, treatment time timing alarm, can the indicating instrument duty, a kind of hypertension instrument that electrode and instrument work are integral.

Task of the present utility model is that following mode realizes: the outfan of DC power supply is received ultra-low frequency oscillation circuit and adjustable timer circuit respectively, the output termination on-off circuit of ultra-low frequency oscillation circuit and indicator light circuit 1, the output termination charge-discharge circuit of on-off circuit and indicating circuit lamp 2, the outfan receiving electrode of charge-discharge circuit, as shown in Figure 1.Low-frequency oscillatory network is by two placed in-line NAND gate circuits, two potentiometers, two electric capacity, and diode is formed.On-off circuit is made up of the audion of one on-off action, resistance, coil, the tongue tube of a metering function.Adjustable timer circuit is connected in series the news Chinese percussion instrument by a NAND gate circuit, resistance, potentiometer, electric capacity to be formed with audion, and indicator light circuit 1 is made up of NAND gate circuit, light emitting diode, resistance.Indicator light circuit 2 is made up of tongue tube, light emitting diode, resistance.Electrode is embedded in the housing appearance and caves in and becomes the shape of coincideing with finger.

Because this utility model has increased audio oscillator circuit, on-off circuit and adjustable timer circuit, needn't be artificially when using this utility model Push switch intermittently, promptly charging and discharging circuit is regular discharges and recharges by the control of low-frequency oscillatory network and on-off circuit, and therefore the cycle of discharge is relatively stable.Setting in advance as required in 10～15 minutes of treatment time controlled by adjustable timer circuit, reminds with audible alarm to the time to stop treatment, needn't oneself see clock and watch control.The indicator light circuit that increases, clearly the duty of indicating instrument when red light does not work, is pointed out the cell voltage deficiency, can not inhale tongue tube, and instrument can not be worked, and must change battery, and indicator light circuit 1,2 is the work process of indicating instruments respectively.Owing to adopt the NAND gate integrated circuit to make this instrument volume littler, can carry.Electrode is to be embedded in the housing appearance and to cave in to become the shape of coincideing with finger, therefore is held in the hand good hand touch, need only pinch instrument on the other hand during treatment, can crouch or read a book and turn over book.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
