Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode holding sheet device for a multi-channel low frequency treatment device.

[0002]

2. Description of the Related Art A low-frequency treatment device has been known as a type of treatment device (physical therapy device) using an electric signal. This low-frequency treatment device is performed by applying a low-frequency electrical signal (low-frequency treatment signal) between a pair of electrodes (conductors) attached to the body surface of a patient. A multi-channel low frequency treatment device having a plurality of pairs of electrodes has also been put into practical use. However, in this multi-channel low frequency treatment device, for applying a low frequency electric signal to a plurality of pairs of electrodes at the same time and applying a low frequency electric signal to many places at once, Alternatively, among a plurality of pairs of electrodes, initially a low frequency electric signal is applied to only a part of the electrode pairs for a long time, and then a low frequency electric signal is applied to another electrode pair for a long time. However, it is not intended to treat the patient by changing the stimulation site to the patient within an extremely short time.

[0003]

By the way, as a type of massage, there is a "rubbing" in which the body surface of a patient is traced by a hand with an appropriate force, and the movement of the hand by this rubbing moves like a circle or an arc. Often referred to as non-linear. It is thought that this "rubbing" cannot be realized in a low-frequency treatment device that is used while the electrodes are fixed to the patient's body surface because the part that gives stimulation to the patient must move sequentially. Was there.

The applicant of the present invention, in a multi-channel low-frequency treatment device having a plurality of output sections for respectively outputting a low-frequency signal for treatment, staggers the outputs from the plurality of output sections in a short time. We have developed a system that has a specific mode that can be sequentially performed. In this one, by arranging a plurality of pairs of electrodes to be mounted on the body surface of the patient at intervals in the direction of the rubbing, one electrode pair to the next electrode pair is sequentially arranged in a short time. By moving the stimulus, a rubbing interval will be obtained.

As mentioned above, in order to obtain the rubbing distance,
In particular, when moving a stimulus in a non-linear manner such as a circle or arc, it is necessary to attach a plurality of pairs of electrodes to the body surface along a predetermined curve (for example, in an arc shape). It is a very troublesome work to set the arrangement of the above for each patient, and some measure is desired in this respect.

The present invention has been made in consideration of the above circumstances, and an object thereof is to easily specify a plurality of electrode pairs in a case of obtaining a massage feeling of a rubbing stimulus that is non-linearly moved. It is an object of the present invention to provide an electrode holding sheet device for a multi-channel low frequency treatment device which can be mounted on the surface of a patient in this state.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following means for solving the problem.
That is, as described in claim 1 in the claims, there is provided an electrode holding sheet device for a multi-channel low frequency treatment device to be mounted on a body surface of a patient, wherein the insulating holding sheet body has one surface side. , A plurality of electrode pairs each including two electrodes, one electrode and the other electrode forming a pair with the one electrode, are provided, and one surface side of the holding sheet body is
The plurality of one-side electrodes are respectively arranged in the first region and are divided into a first region and a second region set so as to at least partially surround the first region, and Of the other side electrodes are respectively arranged in the second region, and the plurality of one side electrodes arranged in the first region are arranged at intervals along the boundary with the second region. At the same time, the plurality of other side electrodes arranged in the second region are arranged at intervals along the boundary with the first region, and the plurality of electrode pairs as a whole are in the first region. And the second region are arranged at intervals along the boundary between the first region and the second region. This allows
Just by attaching the holding sheet body to the patient's body surface,
It is possible to easily attach a plurality of pairs of electrodes, which require a complicated arrangement relationship in order to obtain a rubbing sensation, to the body surface of a patient.

A preferred mode based on the above-mentioned solution method is as described in claims 2 and below in the claims. That is, the number of the electrode pairs may be four or more (corresponding to claim 2). In this case, there are four or more portions to be stimulated, which is preferable for obtaining a sufficient rubbing sensation. The boundary between the first area and the second area may be set to be substantially arcuate or substantially U-shaped (corresponding to claim 3). In this case, it is possible to obtain a feeling of rubbing corresponding to the case of rubbing in an arc shape or a U shape by hand. The second region may surround substantially the entire circumference of the first region, and the plurality of electrode pairs may be arranged in a substantially annular shape (corresponding to claim 4). In this case, it is possible to obtain a feeling of rubbing corresponding to the case where the ring is manually pierced.

A first conductive sheet for improving conductivity, which entirely covers the plurality of one-side electrodes, and the first conductive sheet are formed separately, and entirely cover the plurality of other-side electrodes. A second conductive sheet for improving conductivity, further comprising: a first mounting portion for removably holding the first conductive sheet on the one surface side of the holding sheet body;
A second attachment portion for detachably holding the conductive sheet may be provided (corresponding to claim 5). In this case, the conductive sheet can be easily attached to the holding sheet main body using the attachment portion in order to improve the electrical conductivity between the electrode and the surface of the patient's body. Further, since the conductive sheets are separately used for the first region and the second region, it is preferable in terms of preventing leakage of electric signals between the electrodes, which is not preferable due to the energization relationship.

The first mounting portion and the second mounting portion are integrally formed with the holding sheet body on the one surface side of the holding sheet body, respectively, and the first mounting portion includes:
A vertical wall portion formed so as to surround the first region and protruding from one surface side of the holding sheet main body, and a horizontal wall portion extending from the tip of the vertical wall portion toward the first region side. A vertical wall portion, which has a substantially L-shaped cross section, is formed so as to surround the second region, and projects from one surface side of the holding sheet body, and a tip of the vertical wall portion. And a lateral wall portion extending toward the second region side, the cross-section has a substantially L shape (corresponding to claim 6). In this case, the mounting portion can be easily formed by integrally molding the mounting portion with the holding sheet body. Further, the conductive sheet can be easily attached to and detached from the holding sheet main body only by engaging and disengaging the peripheral portion of the conductive sheet with the mounting portion having an L-shaped cross section.

Each of the electrodes is attachable to and detachable from the holding sheet body by an engaging mechanism of a concave and convex type with respect to the holding sheet body.
An engaging portion formed of a concave portion or a convex portion provided on the one surface side of the holding sheet main body, and an engaging portion formed of a convex portion or a concave portion provided on each of the electrodes and fitted into the engaging portion in a concavo-convex manner. And the engaging portion and the engaging portion each have conductivity, and the current-carrying wiring to each electrode is connected to the engaging portion in the holding sheet body. Can be set (corresponding to claim 7). In this case, each electrode is attached by pressing it against the holding sheet main body, and the electrode is removed simply by separating the electrode from the holding sheet main body. It will be extremely easy. In addition, the electrode can be energized by effectively utilizing the attachment site of the electrode to the holding sheet body. Furthermore, since the wiring for energizing the electrodes is arranged inside the holding sheet body,
The appearance will also be improved.

The first region is set in a substantially rectangular shape, and the second region includes a predetermined first peripheral edge portion of the first area and a second peripheral edge portion connected to one end side of the first peripheral edge portion. It is set in a substantially U-shape so as to surround three sides with the third peripheral edge portion connected to the other end portion of the first peripheral edge portion, and the electrode pairs are made into four sets, and the four one side electrodes in total are provided. Are arranged at four corners of the first region, and two electrodes out of a total of four electrodes on the other side are arranged at positions substantially along the first peripheral portion,
The other two electrodes on the other side are arranged in a distributed manner at positions along the second peripheral edge and positions along the third peripheral edge, respectively.
It is possible to do so (corresponding to claim 8). in this case,
By using four pairs of electrodes, it is possible to obtain a rubbing distance similar to that in the case where a U-shape is manually inserted.

[0013]

According to the present invention, it is possible to easily attach a plurality of pairs of electrodes, which require a complicated arrangement relationship in order to obtain a rubbing sensation, to the body surface of a patient.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, referring to FIGS.
A basic configuration for obtaining a massage effect of a rubbing sensation, which is a special mode as a low frequency treatment device, using a plurality of pairs of electrodes will be described. After that, the relationship between the plurality of electrodes and the holding sheet body that holds the plurality of electrodes will be described with reference to FIG.

In FIG. 1, H is the main body of the multi-channel low frequency treatment device. The main body H is a 4-channel type in the embodiment, and has a total of four output units 1 to 4. A pair of electrodes (conductors) can be connected to each of the output units 1 to 4. That is, the pair of electrodes 1a and 1b are connected to the first output section 1 serving as the first channel via the wirings 1A and 1B. Similarly, a pair of electrodes 2a and 2b are connected to the second output section 2 serving as the second channel via wirings 2A and 2B. A pair of electrodes 3a and 3b is connected to the third output section 3 serving as the third channel via wirings 3A and 3B. The pair of electrodes 4a and 4b is connected to the fourth output section 4 serving as the fourth channel via the wirings 4A and 4B. Thus, in the embodiment,
A total of four electrode pairs are used.

In FIG. 1, T is a treatment table, and K is a patient who lies face down on the treatment table T. The electrodes 1a, 1b to 4
The a and 4b are attached to, for example, the back as a treatment site of the patient K by using a holding sheet body described later.
Accordingly, by outputting a low-frequency signal for treatment (low-frequency electric signal) described later from the output units 1 to 4, between each pair of electrodes 1a and 1b, between 2a and 2b, 3a.
And 3b and between 4a and 4b are stimulated.

FIG. 2 is a block diagram showing a control system used in the present invention. In particular, it focuses on a specific mode for performing a rubbing sensation massage (of ordinary low frequency treatment). For the circuit part for, there is also a part not shown). In FIG. 2, U is a control unit (controller) configured by using a microcomputer. The control unit U includes a CPU, a ROM,
It has a RAM and a system timer. The control unit U includes switches 11 to 11 as independent adjusting means for manually adjusting the magnitudes of the outputs from the output units 1 to 4.
The signal from 14 is input. These switches 11-14
Is a lowering operation unit 11a to 14a for lowering the output,
It has the increasing operation parts 11b to 14b for increasing the output. The lowering operation unit 11a outputs a command signal for lowering the output to the control unit U by being pressed, for example (the same applies to 12a to 14a). Further, the increasing operation section 11b outputs a command signal for increasing the output to the control unit U by being pressed, for example (the same applies to 12b to 14b).

The switch 5 is a decision switch that is manually operated. For example, when the switch 5 is pressed, a command to store the current output states from the output units 1 to 4,
In particular, it outputs to the control unit U a command signal for storing the ratio of the current output magnitude among the output units 1 to 4. The switch 6 is a manually operated common switch as a common adjustment means, and commands the control unit U to issue a command signal for simultaneously changing the magnitudes of the outputs from the output units 1 to 4. The common switch 6 is, for example, of a volume type, and when it is rotated in a predetermined direction, an output increase request is made, and when it is rotated in the other direction, an output decrease request is made. When a request to change the outputs of the output units 1 to 4 by the common switch 6 is received, the control unit U
Performs control such that the magnitude of the output is changed while maintaining the stored output ratio at the time when the determination switch 5 is operated. The common switch 6 can be automatically returned to the zero output state by the motor 7 controlled by the control unit U.

In FIG. 2, reference numeral 8 is a manually operated treatment time setting switch for instructing a desired treatment time (for example, 15 minutes). From the control unit U, D
A control signal corresponding to the therapeutic low-frequency electric signal is output to the / A circuits (digital-analog conversion circuits) 21 to 24. That is, the output units 1 to 4 have the amplifiers 31 to 3
The electric signal from the control unit U is output to the outside, and the control signal from the control unit U to the amplifiers 31 to 34 is the D / A conversion circuit 21.
Through 31. In addition, the control unit U outputs a signal indicating the output state from each of the output units 1 to 4 to the display 9 provided in the main body H at a location easily visible. The display 9 independently displays the output states of the output units 1 to 4, and in the embodiment, the output units 1 to 4 are individually displayed.
The voltage and current output from 4 are displayed. Further, from the control unit U, the amplifier 3
It is adapted to be output to the speaker (buzzer) 36 via the terminal 5.

Next, the output waves from the output units 1 to 4 will be described with reference to FIGS. The output unit 1
Outputs (sizes) from 4 to 4 are voltage values in the embodiment, but current values are also possible. First, as shown in FIG. 3, the electric signals output from the output units 1 to 4 are basically low-frequency electric signals in which square-shaped pulses having a predetermined width (time width) are output at low frequencies. (The pulse interval in FIG. 3 corresponds to a low frequency, for example, the frequency is 1HZ to 999HZ). In the embodiment, the low frequency electrical signal is superimposed with a medium frequency as a carrier (for example, 2KHZ to 10KHZ in frequency). That is,
In the rectangular pulse width of the low frequency signal, the medium frequency electric signals are overlapped, and the burst duty ratio, which is the overlap ratio, is always a constant value (for example, 30%) in the embodiment. This allows the patient K to have low frequency components.
It is effective for giving a stimulus from the body surface to the deep part.

As shown in FIG. 4, the output from each of the output units 1 to 4 is in a continuous output state in which a constant value is maintained for a predetermined time, but the output gradually increases until the continuous output state is reached. The output state is gradually increased, and the output state is gradually decreased from the continuous output state. In this case, the output increase rate in the gradually increasing output state (output increasing rate per unit time) is made smaller than the output decreasing rate in the gradually decreasing output state (output decreasing rate per unit time). In other words, the output increases slowly and the output decreases rapidly. The output increasing ratios of the output units 1 to 4 in the gradually increasing output state are set to be substantially equal to each other, and similarly, the output decreasing rates in the gradually decreasing output state are set to be substantially equal to each other.

The outputs from the output units 1 to 4 are sequentially performed with a time lag between them. For example, the first output section 2 (electrodes 1a, 1b), the second output section 2 (electrodes 2a, 2b), the third
Output unit 3 (electrodes 3a, 3b), fourth output unit 4 (electrode 4
a, 4b) are output in this order. The output order corresponds to the rubbing direction. For example, in the case of FIG. 1, the sense of rubbing clockwise (clockwise) is given in the output order. Contrary to the above output order, the fourth output unit 4
When outputting from the third output unit 3, the second output unit 2, and the first output unit 1 in this order, a sense of rubbing counterclockwise (counterclockwise) in FIG. 1 is given.

A preferred output example is shown in FIG. In FIG. 5, a case is shown in which the first output unit 1, the second output unit 2, the third output unit 3, the fourth output unit, and the like are sequentially output, and the output in this order is repeated. Then, in the example of FIG. 5, the magnitude of the output (continuous output state) is
The second output section 2 has the largest size, the third output section 3 has the smallest size, and the first output section 1 and the fourth output section 4 have intermediate sizes. The sizes of the output units 1 to 4 are different in consideration of the fact that the strength of the stimulus that the patient K feels varies depending on the electrode attachment site even if the output is the same. It is a thing. In other words, the magnitude of the output is adjusted among the output units 1 to 4 so that the same stimulus intensity is felt for each part where the electrodes are attached.

As is apparent from FIG. 5, in the embodiment,
Output delay time (delay time) between the output units 1 to 4
Are set to be substantially equal to each other (for example, the output from the second output unit 2 is started after the output from the first output unit 1 is delayed by a constant delay time t). The output from the third output unit 3 is started with a delay of t from the start of the output).

While the output of the current output section (for example, the first output section 1) being output this time is being performed, the output from the output section (for example, the second output section 2) of the next output is performed. Be started. More specifically, the output from the next output unit is started while the output state at the current output unit is the above-mentioned continuous output state. Then, at the time when the output from the current output unit is stopped (output is zero) (the end of the gradually decreasing output state), the output state at the next output unit is set to the continuous output state. With such a setting, in particular, a feeling that the stimulus continuously moves from one pair of electrodes that are being output to another electrode that is being output next is strongly obtained. In addition to the above, during the transitional period when the output state of the current output unit, which is currently outputting among the plurality of output units 1 to 4, shifts from the continuous output state to the gradually decreasing output state, the next output is performed. The output from the next output unit is set to the start time of the continuous output state.

It should be noted that if the output from the next output section is started after the output from the output section being output this time is completely stopped (output is zero), the feeling of rubbing may be interrupted on the way. It is a bad feeling because it makes me feel like it. Although it is possible to set only the continuous output state as the output state from each output unit 1 to 4 (when neither the gradually increasing output state nor the gradually decreasing output state is provided), in this case, the stimulus is continuously and gradually. It becomes difficult to get the feeling of moving to.

It should be noted that, for example, from the output start from the first output section, the output from the second output section, the output from the third output section, the output from the fourth output section, the output from the first output section is restarted. The time to reach (the time per cycle, which corresponds to the repetition time in FIG. 5) may be set in consideration of the rubbing massage performed by a normal hand, for example, about 0.5 seconds to 2 seconds. It is preferable to set it in the range of 0.8 seconds to 1.5 seconds. Further, this one cycle time can be manually changed (a manual switch for this purpose may be separately provided).

Next, a control unit U for performing the above-mentioned control
The control contents of the above will be described with reference to the flowcharts of FIGS. In addition, a plurality of sets of electrodes 1a, 1b to 4
The patient K is attached to the patient a and 4b as shown in, for example, FIG. 1. In order to give the sensation of turning counterclockwise in FIG. 1, the output order is the first output unit 1, the second output unit. 2, the third output unit 3, and the fourth output unit 4 are in this order. In the following description, Q indicates a step.

First, in Q1, by operating the switch 8, the treatment time is set to, for example, 15 minutes. In Q2, the output from each output unit 1-4
The adjustments are made individually by using the adjustment switches 11 to 14. More specifically, after the treatment time is set in Q1, first, only the first output unit 1 outputs,
Switch 11 (lowering operation part 11a, increasing operation part 1
By operating 1b), the patient K is adjusted so as to obtain the minimum output that feels the stimulus, and the adjusted value is temporarily stored. Then, output is performed only from the second output section 2, and by operating (the operating sections 12a and 12b of) the switch 12, the output is adjusted to the minimum output that the patient K feels, and this adjusted value is adjusted. It is stored temporarily. After that, output is performed only from the third output unit 3, and by operating (the operating units 13a and 13b of) the switch 13, the output is adjusted to the minimum output that the patient K feels. Is temporarily stored. Finally, output is performed only from the fourth output unit 4, and by operating the switch 14 (the operating units 14a and 14b thereof), the output is adjusted to the minimum output that the patient K feels. Is temporarily stored. In this way, the minimum output magnitude for which a stimulus is felt at the attachment site of the electrodes 1a, 1b to 4a, 4b corresponding to each output unit 1 to 4 is set independently for each output unit 1 to 4. , Will be remembered. It is also possible to display on the display 9 which one output unit is currently being output.

At Q3, it is judged if the decision switch 5 has been turned on. If NO in this Q3 determination, the process returns to Q2. If YES in the determination in Q3, in Q4, the magnitude of the output ratio among the output units 1 to 4 stored as described above is stored. As the storage, for example, the third output unit 3 having the smallest output value
The output value of the first output unit 1 is 110%, the output value of the second output unit 2 is 140%, and the output value of the fourth output unit 4 is 120%. It

In Q5, the output values are simultaneously output from the output units 1 to 4 with the ratio of the output stored as described above (in the embodiment, the output value set and stored in Q2 is output as it is). . In the state where the outputs from the respective output units 1 to 4 are simultaneously performed, the patient K is at all the attachment sites between the electrodes 1a and 1b corresponding to the respective output units 1 to 4 to 4a and 4b. , I feel a stimulus of almost the same strength. In this state, in Q6, by operating the common switch 6, the magnitudes of the outputs from the output units 1 to 4 are adjusted so that the patient K feels comfortable. Is an output that gives the weakest stimulus, so the common switch 6 adjusts the direction to increase the stimulus, that is, the direction to increase the output). When the output is adjusted by the common switch 6, the magnitude of the output from each of the output units 1 to 4 is set so that the magnitude ratio of the output stored in Q4 is maintained. As a result, the patient K feels a stimulus of substantially the same magnitude for all electrode attachment sites.

In Q7, the decision switch 5 in Q3 is turned on.
After that, it is determined whether or not a predetermined time (for example, 15 seconds) has elapsed. If NO in this Q7 determination, return to Q5. When the determination in Q7 is YES, in Q8, the simultaneous output from the output units 1 to 4 is stopped, and the sequential output in a predetermined order is started. That is, for example, the output is started in the output mode in the rubbing mode (specific mode) for obtaining the rubbing sensation as shown in FIG.

In Q9, it is determined whether or not the treatment time set in Q1 has elapsed from the output start time in the rubbing mode in Q8. When the determination in Q9 is NO, the process in Q8 is repeated to continue the output mode in the rubbing mode. If YES in the determination in Q9, Q1
At 0, the buzzer 36 is activated to indicate the end of treatment. After that, in Q11, the operation state of the common switch 6 is forcibly driven by the motor 7 to the state of zero output,
After returning, the outputs from all the output units 1 to 4 are stopped.

When outputting in the rubbing mode of Q8, the magnitude of the output from each of the output sections 1 to 4 can be adjusted independently, or the magnitude of the output from all the output sections 1 to 4 can be adjusted. Can be changed at the same time. In this case, for example, the flowchart shown in FIG. 7 is interrupted every predetermined time with respect to the flowchart shown in FIG. In addition,
The flow chart of FIG. 7 is the same as that of FIG. 6 when any one of the switches 11 to 14 or the common switch 6 is operated.
May be interrupted in the flowchart of FIG.

In the flowchart of FIG. 7, first, Q2
1, it is determined whether any of the switches 11 to 14 has been operated. If YES in the determination in Q21, in Q22, the output unit (for example, the first output unit 1) corresponding to the operated switch (for example, the switch 11).
Output from is changed. Further, in this Q22, the output ratios among the output units 1 to 4 are changed and stored as the outputs from some output units are changed.

After Q22 or in the determination of Q21, NO
In each case, it is determined in Q23 whether or not the common switch 6 has been operated. Y is determined by this Q23
In the case of ES, in Q24, the magnitudes of the outputs from the output units 1 to 4 are simultaneously changed while maintaining the stored output ratio. Note that the simultaneous output change is a software simultaneous change, and what is actually implemented as the output change is at each output timing of each of the output units 1 to 4 (sequential output change). If NO in Q23, the process is returned as it is.

Next, a plurality of pairs of electrodes 1a, 1b to 4a, 4b and a holding sheet main body for holding them will be described with reference to FIG. First, the holding sheet main body 41 is denoted by reference numeral 41. The holding sheet main body 41 is formed of, for example, a soft synthetic resin into a thin sheet shape as a whole, and has a thin internal space 42 inside (FIG. 12).

In the embodiment, the electrodes 1a, 1b to 4a, 4b are detachable from the holding sheet body 41. In the embodiment, the attachment of the electrodes 1a, 1b to 4a, 4b to the holding sheet main body 41 is performed by using a concave-convex fitting type locking mechanism such as a hook. Regarding the example of this locking mechanism, the electrode 1
Although a description will be given with reference to FIG. 13 focusing on a, similar locking mechanisms are adopted for other electrodes. That is, the female side member 61 that constitutes the engaging concave portion as the locking portion is fixed to one surface side of the holding sheet main body 41, and the electrode 1
A male member 62 forming an engaging protrusion is fixed to a. By aligning the male member 62 with the female member 61,
By strongly pressing a against the holding sheet body 41, the electrode 1a is fixed to the holding sheet body 41. By peeling off the fixed electrode 1a, the female member 6
The engagement between 1 and the male member 62 is released, and the electrode 1a is removed from the holding sheet body 41.

The cross-sectional shape (the cross-sectional shape in the direction orthogonal to the axis of the engaging direction) of the fitting portion between the female side member 61 and the male side member is circular (or substantially circular) in the embodiment. Therefore, if the female member 61 and the male member 62 are simply engaged with each other, the electrodes 1a, 1b to 4 are
A and 4b will rotate relative to the holding sheet body 41. The anti-rotation mechanism for preventing the relative rotation will be described later.

The female side member 61 and the male side member 62 are each formed of a conductive member, and are formed of, for example, an iron-based metal or a copper alloy in order to secure sufficient strength (rigidity). (For example, the surface of both members 61, 62 may be subjected to a treatment of silver plating or gold plating for improving conductivity). The male member 62 is fixed to the electrode 1a, and its electrical conductivity is always ensured between the male member 62 and the electrode 1a. When the female member 61 and the male member 62 are engaged with each other, by energizing the female member 61, the electrode 1 a is energized via the male member 62. The holding sheet body 41 itself is formed of a soft non-conductive member (insulating member), and even if electricity is applied to the female member 61,
The holding sheet body 41 itself is not energized. In addition, in the embodiment, each of the electrodes 1a, 1b to 4a, and 4b is configured to have overall conductivity by a soft material in which a conductive material such as carbon is mixed, and contacts the male side member 62. Only the male member 6
Energization with 2 is ensured.

The electrode 1a and the holding sheet body 4 as described above
The engagement relationship with 1 is that the other electrodes 1b, 2a, 2b, 3a,
The same applies to 3b, 4a, and 4b. In the thin internal space 42 inside the holding sheet main body 41, the above-mentioned current-carrying wirings 1A, 1B to 4A, 4B are arranged. Each wiring 1
A, 1B to 4A, 4B are collected into a single cable from the portion led out of the holding sheet main body 41,
Although not shown, the external connection ends thereof are collectively connected to a connection coupler. That is, the connection coupler has at least eight connection terminals corresponding to a total of eight wirings 1A, 1B to 4A, and 4B and can be detachably connected to the connection terminals provided on the main body H of the low-frequency treatment device. It is said that That is, FIG.
Then, the respective wirings 1A, 1B to 4A, and 4B are shown individually for the sake of clarity, but in reality, as described above, the low-frequency treatment device is formed in a single cable. It is adapted to be connected to the main body H.

In use, as shown in FIG. 8, the electrodes 1a, 1b to 4a, 4b are attached to the holding sheet body 41.
And then the two conductive sheets 53 and 54 are attached to obtain the state of FIG. Then, the conductive sheet 53,
The patient is contacted with 54 positioned on the body surface side of the patient. In order to surely bring the electrodes 1a, 1b to 4a and 4b into contact with the patient's body surface via the conductive sheet 53 or 54, a separate belt or the like is used to hold the holding sheet main body 41, that is, the electrodes 1a and 1b to. 4a, 4b can be pressed against the surface of the patient's body, and in this case, the belt or the like can be used to prevent displacement of the holding sheet body 41 with respect to the surface of the patient's body. Further, in order to improve the conductive sheet between the electrodes and the patient, as shown in FIG. 14, a plurality of ribs are projected on the surface of the electrodes 1a, 1b to 4a, 4b on the patient side.

Here, when the female member 61 and the male member 62 are made of metal, the members 61 and 62 are formed by the moisture adhering to the conductive sheets 53 and 54 and the sweat generated by the patient. It is conceivable that rust will occur on the.
In order to prevent the generation of rust, it is preferable that both members 61 and 62 be blocked or sealed from the outside. An example of a seal mechanism for this seal will be described. First, FIG.
As shown in FIGS. 9 and 13, a ring-shaped convex seal portion 71 is integrally formed on the holding sheet body 41 (one surface side) so as to surround the female member 61. There is.

Similarly, in each of the electrodes 1a, 1b to 4a, 4b, an annular convex seal portion 72 is integrally formed with the electrodes 1a, 1b to 4a, 4b so as to surround the male member 62. (See FIGS. 13 and 15). Each electrode 1a, 1
When the male members 62 of b to 4a and 4b are engaged with the female member 61 of the holding sheet body 41, the two convex seal portions 71 and 72 are in a close contact state so as to have a double inner-outer relationship. Is fitted with. As a result, the outside, that is, the electrodes 1a, 1
Moisture, sweat, and the like from the b to 4a and 4b sides cause the female side member 61,
It is possible to prevent the male side member 62 from penetrating into the portion, and prevent the rusting of both members 61 and 62. In particular, since each of the convex seal portions 71 and 72 has elasticity, its sealing property becomes extremely good.

Each electrode 1a, 1b to 4a, 4b has a structure shown in FIG.
3, as shown in FIG. 15, a pair of convex sandwiching portions 83 are integrally formed on the outer side in the radial direction of the second convex seal portion 72. The sandwiching portion 83 is formed so as to at least partially surround the second convex seal portion 72 in the circumferential direction, and its inner surface facing the second convex seal portion 2 has an arc shape. Then, the second convex seal portion 72
The gap between the sandwiching portion 83 and the sandwiching portion 83 is substantially the same as the radial thickness of the first convex seal portion 71 formed on the holding sheet body 41, and the convex seal portions 71 and 72 have an inner and outer double structure. The second convex seal portion 72 and the holding portion 8 are engaged with each other.
3, the first convex seal portion 71 is sandwiched in the radial direction. As a result, the state in which the biconvex seal portions 71 and 72 are closely attached in the radial direction is more sufficiently secured. In addition, it is also possible to make the sandwiching portion 83 entirely annular. In addition, a holding portion corresponding to the holding portion 83,
It is also possible to form (integrally mold) on the holding sheet body 41 side, and in this case, the electrodes 1a, 1b to 4a, 4b are formed by the first convex seal portion 71 and the sandwiching portion of the holding sheet body 41.
The second convex seal part 72 is sandwiched in the radial direction.

Here, when the electrodes 1a, 1b to 4a and 4b are formed in a deformed shape, but the fitting portion with respect to the holding sheet main body 41 is only one, the electrodes 1a, 1b to 4a,
It is conceivable that 4b may rotate with respect to the holding sheet main body 41 without permission and be displaced from a desired mounting posture state.
In order to prevent such a situation, the electrodes 1a, 1b-4
The detent mechanism of a and 4b can be separately configured.
In the embodiment, the rotation stopping mechanism includes electrodes 1a, 1b to
Two fitting recesses 81 are formed on the holding sheet body 41 (one surface side) at a position eccentric with respect to the female member 61, which is the center of rotation of 4a and 4b. Corresponding to the fitting recess 81, the electrodes 1a, 1b to 4a, 4
A fitting convex portion 82 is integrally formed with b. Electrodes 1a, 1b to 4 in which a female member 61 is engaged with a male member 62
In the mounted state of a and 4b, the fitting convex portion 82 becomes the fitting concave portion 81.
It is done so that it is fitted to. As a result, the electrodes 1a, 1b to 4a, 4b are connected to the female member 61 (male member 6).
It is possible to prevent the situation in which the electrode 1a, 1b to 4a, 4b freely rotates during use around 2) and to fix the electrodes 1a, 1b to 4a, 4b to the holding sheet body 41 in a desired posture. it can. In order to prevent rotation, the fitting convex portion may be formed on the holding sheet main body 41 side, while the fitting concave portion may be formed on the electrode side. In short, in order to prevent rotation, it suffices to configure the engagement relationship between the holding sheet body 41 and the electrode at a position eccentric to the female member 61 and the male member 62, You may form an engaging convex part in each of the holding sheet main body 41 and an electrode.

Although the embodiment has been described above, the present invention is not limited to this, and includes the following cases, for example. The number of pairs of electrodes (the number of output portions) may be two or more, but three or more, and particularly four or more as shown in the embodiment, a sufficient feeling of rubbing can be obtained. It will be preferable from the above. The output order from multiple output units is
Not only in the case of repeating in the same order, for example, the output order may be reversed after the first output, for example, the first output section 1 is started, and the last output, for example, the fourth output section 4. May be. More specifically, for example, in the example of FIG. 5, the first output unit 1, the second output unit 2, the third output unit 3,
The fourth output unit 4, the third output unit 3, the second output unit 2, the first output unit 1, the second output unit 2, the third output unit 3 ... The output may be inverted. In this way, a switch for manually selecting the repeating mode in which the same output sequence is repeated without changing the output sequence of the plurality of output units and the inversion mode in which the rubbing direction is inverted as described above is provided separately. You can also do it.

The time per cycle until the sequential output from all the output sections is completed once may be changeable, and in this case, a manually operated switch for instructing the change of the time per cycle. May be provided separately. As a result, it is possible to arbitrarily change the speed of rubbing, that is, the feeling of quickly rubbing and the feeling of slow rubbing. The low-frequency electric signal may be one that does not superimpose a medium-frequency carrier wave.

The second area 52 is set to have an annular shape (for example, an annular shape, a square annular shape, an elliptical annular shape), and the first area 51 is formed.
Can also be set so as to entirely surround. For example, the first region 51 may be formed in a substantially rectangular shape or a substantially circular shape, while the second region 52 may be formed in an annular shape (almost annular shape) that entirely surrounds the first area 51. In this case, the number of electrode pairs is 4 or more, for example, 5, 6, or 7.
It is preferable that the number is as large as possible, for example, 8 sets (a plurality of sets of electrode pairs are preferably arranged at substantially equal intervals in the circumferential direction). The electrodes 1a, 1b to 4a, 4b may be always fixed without being detachable from the holding sheet body 41. In addition, each electrode 1a, 1b to 4a, 4b
In order to be attachable / detachable to / from the holding sheet body 41, not only the concavo-convex fitting type but also an appropriate attachment method can be adopted.

The engaging positions of the electrodes 1a, 1b to 4a, 4b with respect to the holding sheet body 41 can be set to two or more positions for one electrode (in this case, it is unnecessary to separately provide a rotation preventing mechanism for the electrodes. Become). Further, the engagement position of the electrode with respect to the holding sheet body 41 and the energization position of the electrode can be separately configured (female side member 6).
(1) and the male member 62 are not used to energize the electrodes).

The female member 61 may be provided on the electrode side, while the male member 62 may be provided on the holding sheet body 41 side. When the energization site of the female side member 61 and the male side member 62 is sealed, for example, an annular concave portion (or convex portion) formed in the holding sheet main body 41, for example, an annular convex portion formed on the electrode side. It can also be performed by fitting parts (or recesses). The seal portion may be, for example, a quadrangular ring or an elliptical ring, instead of the annular shape as a whole, but it is possible to eliminate the existence of the corners and to secure a good sealing property and to facilitate the manufacturing. Etc.,
It is preferable to make it annular.

Although the embodiment has been described focusing on the case where a rubbing sensation is obtained, the electrode holding sheet device of the present invention can also be used for ordinary massage. For example, a therapeutic electrical signal can be applied simultaneously to a plurality of pairs of electrodes, and stimulation can be applied to a plurality of locations at the same time. In addition, after applying a therapeutic signal for a long time (for example, 5 minutes) to only one electrode of a plurality of pairs of electrodes, a long-term electrical signal for therapy is applied to another electrode pair. It is also possible to do so sequentially while changing the electrode pair to which an electric signal is applied (a method of using electrodes that are arranged in advance for a plurality of sites that give long-term stimulation, Since the electric signal is continuously applied to one electrode pair for a long time, it has nothing to do with the rubbing sensation).

The detent mechanism for the electrodes 1a, 1b to 4a, 4b with respect to the holding sheet body 41 is, for example, a female member 6
It is also possible to make the cross-sectional shape of the fitting portion of 1 and the male member 62 different shapes. However, in this case, since the external force for the rotation stop is concentrated on the fitting portion of the female side member 61 and the male side member 62 as the locking mechanism, it is eccentric to the locking mechanism as in the embodiment. It is preferable to separately configure a portion that receives an external force for preventing rotation at the above position.

The conductive sheets 53, 54 can be set so that the vicinity of the central portion thereof is detachably connected to the holding sheet main body 41 by means of a hook or the like at a position where no electrodes are present (conductive sheets 53, 54). Securing a more reliable attachment to the holding sheet body 41 of FIG. Of course, the conductive sheets 53 and 54 may be omitted. Each step (group of steps) shown in the flowchart or various members such as a switch can be expressed by adding the name of the means to the higher level expression of the function. The arrangement of the electrodes can be set arbitrarily, and when a special mode for obtaining a rubbing feeling is not particularly required, for example, the one-side electrodes 1a to 4a are arranged in series along a predetermined straight line and The side electrodes can also be arranged in series with each other along the predetermined straight line. Further, the function of each step (step group) shown in the flow chart can be expressed as the function of the functional unit set in the control unit (controller) (the existence of the functional unit). Of course, the object of the present invention is not limited to what is specified, and also implicitly includes providing what is expressed as substantially preferable or advantageous.
