【Example】

 The low frequency treatment device according to the present invention has a treatment device main body 10 for generating a predetermined treatment signal 11 and an output from the treatment device main body 10, as shown in the overall configuration in FIGS. 1 and 2. And a conductor 12 for applying a therapeutic signal 11 to the skin surface of the affected area.

The conductor 12 includes a flat plate-like electrode 16 on an insulating base 14, and two electrodes 16 covered with a conductive adhesive pad 18 are used as one set. The two electrodes 16 are detachably connectable to a jack 26 provided on the upper surface 24 of the main body case of the medical treatment device main body 10 via a cord 20 and a plug 22 provided at the proximal end of the cord 20. ..

The treatment device main body 10 is provided with an operation unit 32 for performing a manual operation described below and a display unit 34 showing an output state of a therapeutic signal at a front surface 30 position in a rectangular flat body case 28. On the other hand, an output adjusting volume 38 with a power switch 36 is provided adjacent to the above-mentioned jack 26 at a substantially central position on the upper surface 24. Further, inside the main body case 28, an electronic circuit 40 capable of outputting a therapeutic signal to the conductor 12 and a battery 42 for supplying driving power to the electronic circuit 40 are incorporated.

The electronic circuit 40 built in the main body case 28 has a signal output from the oscillating means as a clock signal and a one-chip microcomputer which operates according to a program stored in the ROM as a control means. A part or all of the control unit 44 shown in FIG. 3 is configured by a program, a predetermined signal is sent to the output unit 46, and the necessary therapeutic signal 11 can be output to the conductor 12. The microcomputer has a standby mode in which the power consumption is suppressed to a necessary minimum, and the contents stored in the RAM can be retained even when the power switch 36 is off. Reset signal 45 is sent to start the control unit 44.

When the reset signal 45 is sent to the timer circuit 48, the control section 44 starts the time counting by the timer circuit 48 and enables the continuous sending of the therapeutic signal 11 for up to 15 minutes. To generate a clock signal. The clock signal is further sent to the frequency dividing circuit 52 to reduce the oscillation frequency, and various reference signals of the frequency required by each circuit of the control unit 44 are formed.

For example, as for the reference signal input to the boost signal generation circuit 54, the frequency selection circuit 56 selects a frequency corresponding to the operation mode specified by the operation unit 32 described later, and the booster control circuit 58 further sets the peak value. The predetermined boosting signal 59 is formed by performing the control necessary for the pulsating output of the above, and then is sent to the output unit 46.

In the output section 46, a low voltage of about several volts output from the battery 42 is converted into a high voltage of several tens of volts or higher by using, for example, a chopper type booster circuit 60. That is, by interlocking with the input of the boosting signal 59 having a sufficiently high frequency output from the control unit 44, the current flowing through the choke coil is intermittently generated at high speed to generate a pulse voltage, and the voltage is integrated by the capacitor. That is, a voltage sufficiently higher than the battery voltage is formed.

On the other hand, in response to the selection operation in the frequency selection circuit 56, the drive signal generation circuit 62 of the control unit 44 outputs a drive signal 64 for controlling the generation timing of the therapeutic signal 11 to the high pressure pulse generation circuit 66. Sent to. The high voltage taken out in conjunction with the application of the drive signal 64 is treated by the output current limiting circuit 68 constituted by the volume 38, and then the output polarity switching circuit 70 sets the polarity to a necessary level for treatment. Since the message 11 is formed and sent to the conductor 12, the adhesive pad 18 of the conductor 12 is attached to the affected area so as to be separated from the conductor 12 in advance so that the skin surface between the electrodes 16 is provided with a predetermined amount. The low frequency current flows.

The low-frequency treatment device according to the present invention is provided with a memory circuit 72 in addition to the above-mentioned configuration, and a preset output waveform of the treatment signal 11 can be appropriately selected by a key operation on the operation unit 32. In addition, the output waveform itself set in the memory circuit 72 can be changed.

The operation mode selected by the operation unit 32 includes two types, a “massage” mode in which the output waveform is fixed and a “program” mode in which the output waveform can be newly set or changed. The key groups A and B to be used in each case are arranged in the front surface 30 of the main body case 28 with predetermined area divisions.

In addition to the above-mentioned “massage” mode, low-frequency stimulation imitating “tapping” and “momming” motions in acupressure is repeated while appropriately changing its speed, strength or duration. A "standard" mode that exclusively promotes fatigue recovery, and a "relaxation" that exclusively promotes the relief of pain in muscles etc. by maintaining only the stimulus corresponding to "mom" while changing its strength and duration. A mode is provided, and push-button type keys 74 and 76 are assigned to each mode to form a key group A for the massage mode.

FIG. 4A shows an example of the output waveform of the “battering” signal used in the above-mentioned “standard” mode, where 4 seconds is one cycle, and the pulse frequency is 2 or 5 for each cycle. And 10 Hz, and has a mountain shape as shown by the alternate long and short dash line, the intensity of which peaks at approximately the center of each cycle.

On the other hand, FIG. 4 (b) shows an example of the output waveform of the “fir” signal, where 4 seconds is one cycle and a continuous signal of about 90 Hz is obtained, while about 1 second after the start of each cycle. By basing on a mountain-shaped signal that reaches its peak and then gradually decreases in strength, the pressure applied in acupressure is mimicked as a whole, and the duration and rest period of the signal are Change in 3 steps. In the figure, the shaded area is the continuous signal output period. It should be noted that about 0. A "soft start" is applied in which the peak value gradually increases in 3 seconds.

Regarding the basic waveforms of “Tataki” and “Momi” described above, one in which both polarities are simultaneously output or one in which one polarity is continuously output is defined as one set of basic waveform groups. By combining the basic waveform groups appropriately, 4 sets of waveform blocks within 1 minute are configured. By extracting and outputting these waveform blocks randomly or in a preset order, a low-frequency stimulus with various changes can be applied to the affected area.

FIG. 5 shows an example of the output waveform of the “fir” signal used in the “relaxation” mode, in which the frequency component is so-called “f” without causing a specific periodicity in strength and duration. It is configured to exhibit "1/1 fluctuation" so that the user can be given a natural comfort.

On the other hand, in the “program” mode, an operation key 78 composed of a seesaw switch capable of outputting a single signal corresponding to “tap” and “mom” and a push button for registering and selecting a program. A key group B is formed by using a "favorite" key 80 composed of switches as one set.

Further, one light emitting diode 82.84.86 is provided as the display unit 34 beside each of the "standard", "relaxing" and "favorite" keys 74.76.80, and is selected. The emission state of the therapeutic signal 11 can be visually confirmed by turning on the light emitting diode at the position corresponding to the selected mode using the output signal from the display signal generating circuit 87 in accordance with the output timing of the therapeutic signal 11. I am doing it.

With the above configuration, when the power switch 36 is turned on, first, the “standard” mode is automatically entered, the data corresponding to the mode is taken out from the memory circuit 72, and the predetermined therapeutic signal 11 Is automatically output.

Here, as shown in FIG. 6, when the operation key 78a is tilted to the "tap" side at time t1, a single pulse of both poles is output regardless of the pressing time of the key 78a. When the "Favorite" key 80 is pressed at t2 after a predetermined time after confirming the output, the type of the operated key 78a and the time interval T1 are stored in the memory circuit 72, and thereafter, the "tap" operation is performed at the time interval T1. A single pulse-shaped “battering” signal corresponding to is continuously output.

Similarly, when the operation key 78b is pushed to the “mom” side at time t3 and then the “advance” key 80 is pushed at time t4, the pressing time T2 of the key 78b and the time interval T3 are stored. After that, the “fir” signal corresponding to the “fir” operation is periodically output.

Further, as illustrated in FIG. 7, by switching the operation key 78a to the “tap” side as shown in (a) and switching operation of the operation key 78b to the “muffle” side as shown in (b). After confirming the rhythm that the operator feels preferable, the first 12 and 11 key operations are canceled by pressing the "Favorite" key 80 shown in (c), and 1 to 10 thereafter. Only the information corresponding to the latest ten key operations indicated by the number is stored in the storage circuit 72, and this is continuously repeated as one cycle.

When, for example, 10 seconds that have been set in advance have passed since the operation key 78 was last turned on, the mode selected before then is returned to, and in this state, the “advance” key 80 Even if is pressed, the storage contents in the storage circuit 72 are not set and updated, and the storage state before that is maintained and output. Therefore, the operation key 78 can also be used for temporary manual output control during the automatic output mode of the therapeutic signal 11 by operating the "standard" "relaxation" or "advanced" key 74, 76, 80. ..

Further, once the storing operation is performed, even if the power switch 36 is turned off, the state is maintained, and by simply pressing the “advance” key 80 again, the key operation procedure stored immediately before is stored. , The therapeutic signal 11 is output.

Further, when a key other than the above-mentioned operation keys 78 is operated, a “soft start” is performed in which the peak value of the therapeutic signal 11 reaches a normal value within a predetermined time of about 4 seconds after the switch is turned on. It is configured like. As for the “Momi” key 78b, it takes about 0.3 seconds from the start of the signal output to increase the peak value, and after that, the “soft start” becomes constant, but the “tap” key 78a It is possible to change whether or not to perform soft start at all key operations including.

The present invention is characterized by the arrangement state of the two key groups A and B in the above-mentioned configuration on the main body case 28. That is, as shown in FIGS. 1 and 2, two substantially rectangular recessed grooves 88 and 89 are provided on the front surface 30 side of the main body case 28, and the two sets of keys described above are provided in each groove 88 and 89. Separate the groups A and B.

Each key has a horizontally long elliptical shape and has substantially the same size, and the upper surfaces of the keys are located in substantially the same plane as the peripheral surface of the main body case 28 in the concave grooves 88 and 89. It Furthermore, by making the colors of the two key groups A and B different from each other, a tactile or visually distinct area division is formed between them.

[0035]

 8 and 9 show another embodiment of the structure in which the area division is provided between the key groups A and B. In FIG. 8, the key group A and the "program" for the "massage" mode are shown. The mode key group B is arranged separately on the front surface 30 and the back surface 90 of the main body case 28, and the display window 92 of the output adjusting volume 38 is provided on both sides 30 and 90. ..

On the other hand, in FIG. 9, in addition to the configuration of FIG. 1, by providing a slide type cover 94 that covers the key groups A and B, a sliding operation along the slide groove 96 of the cover 94 is performed. In conjunction with, only one of the key groups A or B is selectively exposed.

It is to be noted that a part or all of the above-mentioned "program" mode side key group B may be covered with an openable / closable cover to prevent unnecessary operation of the key group B. You can Further, instead of or in addition to the above-mentioned concave grooves 88 and 89, it is also possible to divide the two key groups A and B into regions by rib-shaped projections or long grooves.
