Abstract

PURPOSE:To dissolve a polarized condition by equalizing approximately the amt. of a stimulating pulse in the positive pole direction to the amt. of a stimulating pulse in the negative direction. CONSTITUTION:An electric current signal from a pulse wave sensor 31 is input in a microcomputor 35 through a differential circuit 32, a peak hold circuit 33 and a comparator 34. The microcomputer 35 applies a delay to this input pulse to generate a delayed pulse. The microcomputor 35 outputs a drive pulse and a transistor 36 works on and off by a pulse output to a terminal 3a. When the electric current energized in an inductor 37 is made thereby on and off, the inductor 37 generates a reverse electromotive force in accordance with this and it is stored in a condenser 38. When a terminal 3b outputs a pulse, transistors 39b and 39c repeat on and off and the electric charge accumulated in the condenser 38 is discharged to generate a positive pole electric stimulation pulse. During a terminal 3c outputs a pulse, a negative pole electric stimulation pulse is generated in the similar way and at this time, it is set that the amt. of both pulses are approximately equalized each other.

Such an apparatus has three problems.
The above effect is obtained by continuously or intermittently using it for a long time of 0 minutes to 8 hours mainly in the abdomen, but when it is used for a long time, an adverse effect that the conventional electric stimulation device does not occur occurs. The human body, when energized, accumulates charges near the energized area. This electric charge is discharged during the period of a low-frequency treatment device such as a device having a wide interval between electric stimulation pulses, so that the accumulation of electric charge does not pose a problem. However, in reality, it was not completely discharged, and some electric charge remained. This electric charge is not a problem for a short time use, but when used for a long time, the electric charge causes reddening of the skin and electric burns. In order to remove this electric charge, a depolarizing means has been proposed, which is mainly configured to short-circuit the electrical conductors and the non-insulators between electrical stimulation pulse intervals with an electrical switching element. However, the electrical switching element has an on-resistance, and electrical stimulation having a high energy does not completely discharge, so that it is not very effective when used for a long time. Although a device that applies a pulse of reverse polarity as a depolarizing means, which is not an electrical stimulator, has also been proposed, a stimulating pulse having high energy such as electrical stimulation can be obtained by simply adding a reverse pulse. It was insufficient when it was added to the human body for a long time.

In view of the above, according to the present invention, in an electrical stimulation pulse generated between pulse wave pulse intervals, the amount of stimulation pulse in the positive direction and the amount of stimulation pulse in the negative direction are made approximately equal. As a result, it was possible to eliminate the polarization state. The pulse amount shown in the present invention is a value determined by the pulse amplitude and pulse width of one electrical stimulation pulse. Further, the term "approximately equal" is because the present invention changes the output state of the stimulation pulse depending on the state of the pulse wave, and in consideration of this change, it is sufficient if the settings are approximately equal. Since the polarization can be eliminated in the above, it is shown that the width is similarly given.

Next, the operation will be described with reference to FIG. The pulse wave sensor (31) is attached to various parts of the living body and converts a change in blood flow into a change in electric potential (Fig. 2 (21)). This change in potential is converted into a current signal and input to the differentiating circuit (32). The blood flow signal is converted into a differential signal in the differentiating circuit (32) and output to the peak hold circuit (33) and one end of the comparator (34). The peak hold circuit (33) outputs a voltage holding this peak potential when the peak of the differential signal is input, and this voltage is output to the comparator (3

The potentials of the differential signals are compared, and when a predetermined potential difference occurs, a pulse is output ((22) in FIG. 2). The pulse has a pulse width with a peak region rising and a bottom region falling. The microcomputer (35) inputs this pulse, and several (μsec) to several tens (mse)
The delay of c) is applied to generate a delayed pulse whose rising edge is delayed. The pulse width of this delayed pulse is the electrical stimulation output allowable period. The microcomputer (35) outputs the drive pulse to the terminal (3a), the terminal (3b) and the terminal (3c).
The pulse output to the terminal (3a) is a rectangular wave pulse having a frequency of several KHz, and the transistor (36) is turned on and off by the pulse. When the transistor (36) is turned on / off, the current flowing through the inductor (37) is interrupted. When the current is interrupted, the inductor (37) generates a counter electromotive force and is stored in the capacitor (38) via the diode. The terminals (3b) and (3c) output a few (Hz) rectangular wave pulses, and when the terminal (3b) outputs a pulse, the transistors (39b) (39c) turn back on and off. The electric charge accumulated in the capacitor (38) is transferred to the output terminal (40) of the transistor (39c) and the load (RZ) transistor (39).
b) is discharged to generate a positive electrode electrostimulation pulse,

3)). At this time, the amount of electrical stimulation pulse output from the terminal (3b) and the amount of electrical stimulation pulse output from the terminal (3c) may be set to be approximately equal, and various modes are presented. For example, FIG. 2 (23) is an example in which a positive pulse stimulation pulse is continuously output at one pulse wave pulse interval, and then a negative pulse electrical stimulation pulse is output by the same amount in the positive pulse direction. .. In addition, FIG. 2 (24) is one in which electrical stimulation pulses are alternately output.
