Hereinafter, an electrical stimulation device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  Referring to FIG. 1, an electrical stimulation device 1 according to an embodiment of the present invention includes a plurality of suction conductors 2a and 2b, two suction conductors 2a and 2b, a suction pump 3 and suction conductors 2a and 2b. And a steam / water separation tank 4 serving as a steam / water separation means that separates moisture from the air sucked by the suction conductors 2a and 2b.

  One end side of suction pipes 5a and 5b is connected to each suction conductor 2a and 2b in an air communication state. The steam / water separation tank 4 has a plurality of air suction ports 4a, and one end side of the suction pipe 6 is connected to the air suction ports 4a. The other end sides of the suction pipes 5a, 5b; 6 are connected by connectors 7a, 7b, respectively.

  One end side 9 a of the suction pipe 9 from the suction pump 3 is arranged inside the steam-water separation tank 4. The steam-water separation tank 4 is provided with a partition 10 that partitions the first space S1 in which the air suction port 4a is provided and the second space S2 in which the one end side 9a of the suction pipe 9 is disposed. It is done.

One end side 9 a of the suction pipe 9 is provided above the second space S <b> 2 inside the steam / water separation tank 4. The lower part of the steam-water separation tank 4 forms a water storage part 11, and a drain port 4 c is provided on the bottom surface 4 b of the steam-water separation tank 4. One end of a drain pipe 12 with a drain valve 12a is connected to the drain port 4c. The other end of the drain pipe 12 faces the drain tank 13. As shown in FIG. 2, each set of suction conductors 2 a and 2 b is mounted in pairs on the electrical stimulation treatment site of the human body 15.

  Returning to FIG. 1, the control unit 14 can apply an electrical stimulation current to each of the suction conductors 2a and 2b, and the treatment modes include, for example, a low frequency treatment mode, a medium frequency treatment mode, and an interference wave. An electrical stimulation current can be applied to each suction conductor 2a, 2b in three treatment modes of the treatment mode. Detailed description of these treatment modes is omitted. Of course, the treatment mode is not limited to these.

  Further, the control unit 14 is composed of a microcomputer, and according to a control program stored in the memory, the electrical stimulation current is applied to the suction conductors 2a and 2b according to the treatment mode, and the suction pump 3 is turned ON / OFF. Operation, opening / closing operation of the drain valve 12a attached to the drain pipe 12, ON / OFF operation of a power supply (not shown), setting of the types of the suction conductors 2a and 2b, and control according to the setting conditions of the electrical stimulation treatment can be performed. it can.

In the above configuration, when the suction conductors 2a and 2b are attached to the human body 15, the water-containing sponge 14 containing moisture is disposed in the suction conductors 2a and 2b. The reason why moisture is contained in the water-containing sponge 14 is to allow the electrical stimulation current from the energizing electrodes inside the suction conductors 2a and 2b to be suitably applied to the human body 15.

Then, when the suction pump 3 is driven by the control operation of the control unit 14, the air in the space surrounded by the suction conductors 2a and 2b and the human body 15 is sucked, and the internal pressure of the space becomes negative pressure. The conductors 2a and 2b are attached to the human body 15. Then, when the controller 14 recognizes that the attachment of the suction conductors 2a and 2b to the human body 15 is completed, the controller 14 applies an electrical stimulation current to the electrodes inside the suction conductors 2a and 2b, thereby causing electrical stimulation to the human body 15 Control the treatment.

When the suction pump 3 is driven, the moisture contained in the water-containing sponge 14 disposed inside the suction conductors 2a and 2b is sucked from the inside of the suction conductors 2a and 2b, and the suction pipes 5a and 5b, the connectors 7a and 7b, and the suction pipes. 6 is sucked into the steam / water separation tank 4 through the air suction port 4 a of the steam / water separation tank 4.

The air and water sucked into the steam / water separation tank 4 are separated in the steam / water separation tank 4. That is, the water collides with the partition 10 inside the steam / water separation tank 4, adheres to the partition 10, and falls downward in the first space S <b> 1 from the inner wall of the partition 10 by gravity. The dropped water is stored in the water storage section 11 at the lower part of the steam / water separation tank 4. In addition, the control part 14 can control the collision speed of the said water | moisture content with respect to the partition part 10 of the steam-water separation tank 4 by controlling the action | operation of the suction pump 3. FIG. This control makes it possible to control the amount of water that is separated from the steam. In addition, although the partition part 10 is comprised by one flat flat plate shape which opposes the air suction port 4a of the steam-water separation tank 4, it is not necessarily limited to a flat flat plate shape, and faces the air suction port 4a. It may be a convex curved surface, a concave curved surface, or any other shape.

On the other hand, the air moves from the first space S1 to the second space S2 by the suction operation of the suction pump 3, and is sucked from one end side 9a of the suction pipe 9. In this way, water is not sucked into the suction pump 3 and only air is sucked.

Therefore, in this embodiment, water is separated from the air sucked from the suction conductors 2a and 2b by the air / water separation tank 4, and therefore even if filth is mixed in the water, Will not be sucked by the suction pump 3, and the suction pump 3 will not fail due to sucking water mixed with filth.

In addition, a filter for treating the remaining filth is not required inside the electric stimulator 1, so that it is not necessary to replace the filter, and maintenance such as cleaning of the inside of the apparatus is reduced, so that labor and cost are reduced. Is reduced. Furthermore, since a filter is not required, the apparatus can be simplified and reduced in price, and the risk that the user mishandles and breaks down can be eliminated.

  Furthermore, in this embodiment, since the one end side 9a of the suction pipe 9 is provided in the upper position inside the steam-water separation tank 4 as an air suction port of the suction pump 3, the water | moisture content containing filth is the one end side 9a. And the suction pump 3 is more unlikely to malfunction due to suction of water mixed with filth.

  Moreover, in this embodiment, the partition part 10 is provided in the vicinity of the air suction port 4a inside the air / water separation tank 4, and after dirt or moisture adheres to the inner wall of the first space S1, the inner wall lowers due to gravity. , And is accumulated in the water storage section 11 at the lower part of the steam / water separation tank 4, so that moisture containing filth can be more reliably separated from the air, and the malfunction of the suction pump 3 can be more reliably prevented. Processing can be performed easily.

  Moreover, in this embodiment, since the drainage pipe 12 with the drainage valve 12a is provided in the steam-water separation tank 4 as drainage means, and this drainage valve 12a is opened and closed by the control part 14, the steam-water separation tank 4 Sewage can be easily drained from the lower reservoir 11. In this case, the steam-water separation tank 4 is provided with a communication hole 4d communicating with the atmosphere, and when draining, the suction pump 3 is turned off and the drain valve 12a is opened, so that the steam-water separation tank 4 naturally. The water stored in the three water storage chambers 4b can be drained. The communication hole 4d prevents the inside of the steam-water separation tank 4 from becoming excessively negative pressure when air is sucked by the suction pump 3.

  Next, the schematic structure of the suction conductors 2a and 2b will be described with reference to FIG. 3. The suction conductors 2a and 2b are made of rubber or a resin having flexibility and a suction cup portion having an elastic restoring force. 20, a cylindrical pipe portion 21 with a hole 21 a, and an electrode 22 for conducting electrical stimulation current are provided as main components. The space between the inner peripheral surface of the elastic annular protrusion 20 a provided on the inner wall of the suction cup portion 20 and the outer peripheral surface of the cylindrical pipe portion 21 is a seal portion 24. The upper surface side of the electrode 22 is an air passage 25 of the cylindrical pipe portion 21. In the state shown in FIG. 3A, the seal portion 24 is sealed so that the inner peripheral surface of the annular protrusion 20 a and the outer peripheral surface of the tubular pipe portion 21 are in close contact with each other, and the suction cup portion 20 and the air passage 25 are sealed. And is blocked.

  Next, when the suction cup portion 20 is pressed against the surface of the human body 15 and deformed as shown in FIG. 3B, the water-containing sponge 14 is compressed and moisture is released, and the electrode 22 contains moisture contained in the water-containing sponge 14. Is attached and energized, and the annular protrusion 20a is deformed in the direction of the arrow in the drawing, whereby the inner peripheral surface of the annular protrusion 20a and the outer peripheral surface of the cylindrical pipe portion 21 are eliminated, and the seal portion 25 is opened, and the suction cup portion 20 and the air passage 25 communicate with each other.

Then, the suction cup 2 is maintained at a negative pressure by air suction of the suction pump 3, and the suction conductors 2 a and 2 b are sucked and attached to the human body 15.

Thus, in this embodiment, since the suction cup part 20 of the suction conductors 2a and 2b has a self-sealing structure, when the suction conductor is not attached to the human body, a separate on-off valve or the like is not provided. The air passage of the suction conductor can be blocked. Therefore, regardless of whether or not the suction conductors 2a and 2b are attached to the human body 15, it is possible to suitably maintain the airtight state inside the air / water separation tank, and to maintain the inside of the air / water separation tank 4 at a constant negative pressure, There is no worry about dropping of the suction conductors 2a, 2b during the electrical stimulation treatment.

  The structure of the connectors 7a and 7b will be described with reference to FIG.

The connector 7a on the side of the suction conductors 2a, 2b has connecting portions 7a1, 7a2 to which the suction pipes 5a, 5b are connected, and a connecting portion 7a3 to which the connector 7b is connected, and these connecting portions 7a1, 7a2, 7a3 communicates with the internal passage 7a4. A communication hole 7a5 is formed in the inner wall of the connecting portion 7a3.

On the other hand, the connector 7b on the side of the steam-water separation tank 4 has a connector cap 7b1, a self-seal cap 7b2, a spring seat 7b3, a compression spring 7b4, and a connecting hole 7b5. 7b3 is pressed in the direction of the self-seal cap 7b2. Therefore, in the state of FIG. 4A, the spring seat 7b3 contacts the self-seal cap 7b2, and the space between the spring seat 7b3 and the self-seal cap 7b2 is sealed to form a seal portion 7b6.

4B, the connecting portion 7a3 of the connector 7a on the suction conductors 2a, 2b side is inserted into the connecting hole 7b5 of the connector 7b on the air / water separation tank 4 side against the compression spring 7b4. Then, the spring seat 7b3 is retracted, and the seal portion 7b6 formed by the self-seal cap 7b2 of the connector 7b and the spring seat 7b3 is opened.

When the seal portion 7b6 is opened, the air from the suction pipes 5a and 5b flows from the connection hole 7b5 of the connector 7b and the back space 7b6 of the spring seat 7b3 via the internal passage 7a4 and the communication hole 7a5 of the connector 7a. It is sucked into the suction pipe 6.

Thus, in this embodiment, since the connector 7b that connects the suction conductors 2a, 2b and the steam / water separation tank 4 has a self-sealing structure, when the suction conductor is not connected to the steam / water separation tank, it is separately provided. In addition, the air passage of the connector can be shut off without providing an on-off valve. Therefore, regardless of whether or not the suction conductors 2a and 2b are connected to the steam / water separation tank 4, the air / water separation tank 4 can be preferably kept airtight, and the inside of the steam / water separation tank 4 can be maintained at a constant negative pressure. The suction conductors 2a and 2b during electrical stimulation treatment are not worried about dropping off.

In addition, although the partition part 10 is provided in the steam-water separation tank 4 of embodiment for the steam-water separation, this partition part 10 is not essential, for example, as shown in FIG. In the figure, the water contained in the air sucked into the steam / water separation tank 4 from the suction pipe 6 may drop on the water storage part 11 by gravity so that the steam / water can be separated. Good. In this case, since the partition part 10 does not need to be provided, the structure of the steam-water separation tank 4 is simplified.

Further, as shown in FIG. 6, a suction port 4 a is provided in the upper left wall of the steam / water separation tank 4 in the figure, and water contained in the air sucked into the steam / water separation tank 4 from the suction pipe 6 is stored in the water storage unit 11. You may make it fall by gravity so that it may be separated. In the case of the steam / water separation tank 4 of FIG. 6, it is not necessary to make it long in the left-right direction as shown in FIG. 5 or to provide the partition portion 10, so the steam / water separation tank 4 can be simplified and miniaturized. preferable.

  As described above, in the present embodiment, moisture is separated from the air sucked from the suction conductors 2a and 2b by the air / water separation tank 4, and therefore, even if filth is mixed in the water, The suction pump 3 does not suck water mixed with filth, so that the suction pump 3 does not fail due to sucking water mixed with filth.

  Moreover, in this embodiment, since the filter for processing the remaining filth is not required in the electrical stimulation device 1, it is not necessary to replace the filter, and maintenance such as cleaning of the inside of the device is not required. And costs are reduced. Furthermore, since a filter is not required, the apparatus can be simplified and reduced in price, and the risk that a user may cause a malfunction due to incorrect handling can be eliminated.

In addition, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, It can change suitably variously within the range which does not deviate from the meaning.
