[0002]

2. Description of the Related Art As an interference low-frequency therapeutic device, a quadrupole interference low-frequency therapeutic device having two pairs of electrodes, that is, having four electrodes, has been put into practical use. A high-frequency current having a slightly different frequency is applied, and a treatment is performed using a low frequency generated by interference of two high-frequency waves (interference sites are four in total between adjacent electrodes). In such an interference low-frequency treatment device, an electrode for contacting the patient's body surface is arranged in the suction cup, and the suction inside the suction cup is suctioned at a negative pressure, so that a strong suction action of the suction cup on the body surface is used. Then, it is general to ensure electrical contact of the electrode with the body surface.

[0003] Among the recent interference low-frequency treatment devices, a six-pole interference low-frequency treatment device is partially put into practical use.

As described above, in a practically used six-pole interference low-frequency therapeutic device, two electrodes are used.

In particular, in the case of an interference low-frequency treatment device, the number of parameters that can be changed becomes extremely large, so that manual setting is not only troublesome, but setting each parameter manually is effective. Even when it is not a cure.

According to the fourth aspect, it is possible to prevent a negative pressure leak from an unused connection terminal at the time of quadrupole interference low frequency treatment by using the electromagnetic switching valve. According to the fifth aspect, leakage of negative pressure from the connection terminal can be prevented by removing the connection jack from the connection terminal that is not used during quadrupole interference low frequency treatment.

And a switching function for selectively connecting to either the air or the atmosphere.

The control unit U controls the operation of the motor 22 and the switching of the switching valve 28. For this reason, the control unit U is provided with the connection terminals 1A to 3A rather than the switching valve 28.
On the B side, a pressure signal from the pressure sensor PS connected to the passage 24 is input. Needless to say, the pressure sensor PS detects the pressure of the connection terminals 25A to 27B (the pressure in the suction cup described later).
Is detected. The operation of the motor 22, that is, the pump 23, and the control of the switching valve 28 are feedback-controlled so that the pressure detected by the pressure sensor PS becomes a predetermined pressure.

In FIG. 2, 31A-33B are electrodes, 4
1A to 43B are suction cups. These electrodes 31A-33B
Are arranged in the corresponding suction cups 41A to 43B,
One example is shown in FIG. In FIG. 3, the electrode 31A and the suction cup 41A are shown as an example, but the other electrodes and the suction cup are similarly configured. In FIG. 3, the electrode 31A
Is in contact with the patient's body surface 35 via a conductive member 34 such as a sponge. By sucking the inside of the suction cup 41A under a negative pressure, the suction cup 41A is adsorbed on the body surface 35, and thereby the electrode 31A is connected to the body surface 35 via the conductive member 34.
Will be electrically contacted (connected) with reliability.

Referring again to FIG. 2, each of the electrodes 31A-33
B is a connection jack 5 independently via electric wiring.
1A to 53B. Similarly, each suction cup 41A-4A
3B are independently connected to the connection jacks 51A to 53B via negative pressure piping. The electric wiring and the negative pressure pipe are combined into one flexible connection cord 61A to 63B for each electrode (each suction cup).

The connection terminals 1A to 3B and the connection jack 51
An example of a connection structure with A to 53B is shown in FIG. In FIG. 4, 1A and 51A are shown as examples, but the other connection terminals and connection jacks are similarly configured. First, the connection terminal 1A has a valve chamber 72 in a main body 71 having an insulating function, and the branch passage 25A is connected to a base end side of the valve chamber 72. The distal end side of the valve chamber 72 is opened to the outside via a connection passage 73.
A conductive member 73a for electrical connection is fixedly disposed on the inner surface of the connection passage 73, and the conductive member 73a is
The high-frequency electric signal as described in FIG. 1 is applied.

A check valve (check valve) 7 is provided in the valve chamber 72.
4 are configured. The check valve 74 is connected to the connection passage 73.
The valve seat 75 is formed at a base end of the valve seat 75, a ball 76 is attached to and detached from the valve seat 75, and a spring 77 urges the ball 76 toward the valve seat 75. The urging force of the spring 77 is sized to allow the ball 76 to be seated on the valve seat 77 even when sucked from the branch passage 25A under the maximum negative pressure.

On the other hand, the connection jack 51A has an elongated fitting portion 81 made of a conductive member. This fitting portion 81
It is cylindrical and has such a thickness that it can be inserted into the connection passage 73 without play. When the fitting portion 81 is inserted into the connection passage 73 at a predetermined depth, the fitting portion 81
Presses and displaces the ball 76 against the spring 77 to open the connection passage 73. In this state, the fitting portion 81
Is communicated with the branch passage 25A via the valve chamber 72, and communicates the branch passage 25A with the suction cup 41A. Further, the outer peripheral surface of the fitting portion 81 is brought into contact with the conductive member 73a (energization to the electrode 31A). Although not shown, the fitting portion 81
The fitting is prevented from being easily disengaged from the connection passage 73 by, for example, a click mechanism.

FIG. 5 shows the connection terminals 1A to 3B described above.
In the figure, reference numeral 81 denotes a main body case of the low frequency treatment device. In the arrangement example of FIG.
The connection terminals 1A to 2B are arranged in an aggregate state in order to be used for quadrupole interference low frequency treatment. Also, the remaining 2
Since the four connection terminals 3A and 3B are used only during 6-pole interference low frequency treatment, the four connection terminals 1A to 2B are used.
B is set at a position separated from B. In FIG. 5, reference numerals 82 to 84 are color-coded display (linear) to clearly show a pair of connection terminals.

In the embodiment, the low frequency interference therapy is performed, for example, as follows. First, in the case of 6-pole interference low-frequency treatment, six electrodes 31A to 33B (six suction cups 41) are used.
A to 43B) are used. For example, when treating a patient's knee, the first set of electrodes 31A and 31B are arranged (adsorbed) on the front and back of the knee (X-axis direction arrangement). Further, the second set of electrodes 32A and 32B are arranged on the left and right sides of the knee (Y-axis direction arrangement). Further, the third set of electrodes 33A and 33A
B are arranged in front of and behind the knee (Z-axis direction arrangement). Of course, each electrode is fixed to the body surface using the suction of the corresponding suction cup to the body surface.

By applying three kinds of high frequencies having slightly different frequencies to each of the electrodes 31A to 33B as described with reference to FIG. 1, the treatment by the low frequency generated by the interference is performed three-dimensionally. Become.

In the case of quadrupole interference low frequency treatment, the electrode 31A
To 32B (suckers 41A to 42B) are used, and the electrodes 33A and 33B (suckers 43A and 43B) are not used. The connection jacks 51A, 51B corresponding to the unused electrodes 33A, 33B are connected to the connection terminals 27A, 27B.
, The negative pressure leakage from the unused connection terminals 27A and 27B is prevented by the action of the check valve 74.

The control unit U controls the above-described circuits and the like in accordance with the operation states of various manually operated switches. Examples of the manually operated switches include the following. First, as a switch for negative pressure control, a suction ON / OFF (execution / stop) switch P1, a suction mode switch P2,
Suction pressure changeover switch P3 (for example, 30 mmHg
It can be set within the maximum range of 300mmHg), automatic suction mode
A switch ON / OFF switch P4, a command switch P5 for starting suction, and a switch P6 for suction time (unnecessary when automatically setting the same as the treatment time of the switch D6).

As the negative pressure suction mode in the suction cup, for example, mode 1 and mode 2 are set. Mode 1 also:
In addition to the continuous suction at the selected constant negative pressure value, the number of changes in which the suction negative pressure is changed at a high frequency up and down by a predetermined amount around the constant negative pressure value is set (for example, per second, 15 times, 30 times, 60 times, automatically variable between 15 and 30 times, automatic variable between 30 and 60 times). In the mode 2, the suction negative pressure is automatically variable. In particular, the suction pressure is slowly changed for the fir effect. For example, three modes of "strong", "medium" and "weak" are used.
The type has been set. More specifically, when it is "strong", the solenoid valve 28 is released to the atmosphere for 0.3 seconds per second, for example, when it is "medium", it opens for 0.2 seconds, and when it is "weak", it Release for 0.1 second.

When the automatic suction mode is turned on, the first predetermined time (for example, 30 seconds) from the start of suction and the manually set suction time are prioritized to the manually set negative pressure suction mode. A second predetermined time from the end (for example, 30
Only during this period, continuous suction is performed with a constant negative pressure value automatically set. During the first predetermined time, a constant negative pressure suitable for adsorbing the suction cup to the body surface of the patient is automatically set (for example, continuous suction at 100 mmHg). During the second predetermined time, the suction negative pressure is set to a constant value, and the magnitude of the negative pressure at this time is preferably set as small as possible within a range where the suction cup does not fall from the body surface.

Next, as the output relationship of the interference low frequency, a switch (change) switch D between quadrupole interference treatment and hexapole interference treatment
1. Changeover switch D2 for fundamental frequency α, changeover switch D3 for frequency β, changeover switch D4 for presence / absence of modulation and its modulation degree, changeover switch D5 for existence / absence of burst and its degree, changeover switch D6 for treatment time (output time) , A changeover switch D7 for the output intensity.

In addition to the switches D1 to D7, a plurality of combinations of output relations are set in advance as the first mode, and an arbitrary one output mode is selected from the plurality of combinations. A manual switch D8 is provided. The plurality of types of combinations are combinations of presence / absence of modulation, degree of modulation, and presence / absence of vectors (vectors are described later).

The following seven combinations are set, for example. Combination 1: no modulation, no vector Combination 2: no modulation, 5 seconds Combination 3: 75% modulation, no vector Combination 4: 100% modulation, no vector Combination 5: 25% modulation, 5 seconds vector Combination 6: 50 modulation %, Vector 5 seconds Combination 7: modulation 75%, vector 5 seconds

To explain the above vectors, "with vector" means that the interference part is changed by making the output level different between the electrodes of each set, and "without vector" means that the output level between the electrodes of each set is changed. At the same output level. FIG. 7 shows an example of the case with the vector, for simplicity, in the case of quadrupole interference low frequency treatment. In the example of FIG. 7, while maintaining one set of electrodes at the set output level for a predetermined time (vector time, 5 seconds in FIG. 7), another set of electrodes is set to the set output level only during this predetermined time. This is performed by gradually changing the output level to a predetermined ratio (50% in FIG. 7) level. In addition,
In the example of FIG. 7, a predetermined time (30 in FIG.
Until the time elapses, each set of electrodes is maintained at the set output level.

For each of the above combinations, the interference low frequency (β,
2β) is set in advance. For example, the magnitude of the interference low frequency is small (from low frequency to high frequency), small (low frequency, for example, 1 to 10 HZ), medium (medium frequency, for example, 3 to 30 H).
Z) and large (high frequency, for example, 80 to 120 HZ). For each of the above combinations, low frequency is performed for a predetermined time (for example, 240 seconds), and then high frequency is performed for a predetermined time (for example, 120 seconds). This is repeated thereafter (when the frequency is changed, it is preferable to gradually change the interference frequency). At each of the above frequencies, the frequency can be automatically and gradually changed between the upper limit frequency and the lower limit frequency. In this case, the time (sweep time) per transition from the upper limit frequency to the lower limit frequency and back to the upper limit frequency may be automatically set or may be set manually (a plurality of preset sweeps). Control may be performed at 1 / F (F is frequency), which is so-called "fluctuation".

The treatment time (for example, 15 minutes) may be automatically set in advance for each of the combinations, and the frequency of the basic carrier may be automatically set to, for example, 5000 HZ which is software.

The magnitude (frequency) of the interference low frequency described above is
A plurality of types may be set in advance separately from the above combinations, and a manual selection may be made from the plurality of types of frequencies using a separately provided manual switch. FIG.
The frequency switching circuits 15B and 15C may output a frequency subtracted from the basic high-frequency frequency α based on the set low-frequency frequency β.
β, and 15C outputs α-2β).

Although the embodiment has been described above, the present invention is not limited to this, and includes, for example, the following case. For example, the output of the frequency setting circuit 16 of FIG. 1 is input to the output circuit 14C by bypassing the frequency conversion circuit 15C and the modulation circuit 13C, so that low-frequency treatment using only two poles (connection terminals 3A and 3B) is performed. (Selection by a manual switch for switching between two poles, four poles, and six poles). When the two-pole low-frequency treatment is selected, the circuits corresponding to the other electrodes not used are stopped.

In order to prevent negative pressure transmission to some unused suction cups (prevention of negative pressure leakage), the structure shown in FIG. 4 has electrodes 33A, 3A used only for 6-pole interference low frequency treatment.
You may make it use only about 3B. Further, instead of or in addition to the structure shown in FIG. 4, as shown by a dashed line in FIG. 2, an electromagnetic on-off valve 85 is provided in a negative pressure passage corresponding to the electrodes 33A and 33B, and the electrodes 33A and 33B are provided.
When the 3B is not used, the solenoid valve may be closed.

The frequency conversion circuits 15B and 15C shown in FIG. 1 are set so that the interference frequency is set so that one of them has an integral multiple of the other (two times in the embodiment). This is preferable for obtaining different interference frequencies while sharing the setting circuit 16. Of course, if a frequency setting circuit 16 is separately provided for each of the frequency conversion circuits 15B and 15C, it is possible to select a finer interference frequency.

Various members such as a sensor and a switch can be expressed by adding a name of a means to a higher-level expression of its function. Further, the object of the present invention is not limited to the specified one,
It implies to provide what is expressed as substantially preferred or advantageous. Further, the present invention can be expressed as a control method.
