  In the best mode of the present invention, a head electrode 5 for generating a high electric field between the lower electrode 6 and the lower electrode 6 is attached to the backrest portion 7 of the foldable chair so as to be movable up and down. A lifting device 12 that moves the head electrode 5 up and down, and an optical sensor (head position detection unit) 18 for detecting the height position of the head of the patient P sitting on the seat 8 are provided. Even when the height of the head of the patient P is changed by controlling the drive unit 12A of the lifting device 12 in response to the detection signal of the sensor 18 to automate the height adjustment of the head electrode 5. The first gist is to perform the potential treatment.

  Further, the high voltage cable 15 connected to the head electrode 5 and the low voltage cable 16 connected to the optical sensor 18 and the like are arranged on both the left and right sides of the lifting device 12 for raising and lowering the head electrode 5. The transparent insulating member 27 for preventing discharge, which is disposed separately from each other and provided between the optical sensor 18 and the head of the patient P, is made of a transparent resin material and supports the transparent insulating member 27. Since the overlapping portion for increasing the creepage distance is formed between the arm (mounting member) 9 and the transmission efficiency with respect to the light emitted from the optical sensor 18 is increased, the discharge can be effectively prevented. In addition, the purpose of carrying out and storing the electric potential therapy apparatus 1 easily was achieved. A high voltage of, for example, about 4500 volts to 30000 volts is applied between the head electrode 5 and the lower electrode 6 by a high voltage generator according to the condition of treatment.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1, FIG. 2 and FIG. 3 are a front perspective view, a rear perspective view and a side view, respectively, showing the potential treatment device 1 according to the present embodiment. The potential treatment device 1 includes a potential treatment device 2 and a high level not shown. It is roughly composed of a voltage generator and a commercial power source.

  As shown in FIG. 1, the potential treatment device 2 includes a chair 4 with an armrest 3 on which a patient P is seated, and a head electrode 5 to which a high voltage of 4500 volts, for example, is applied from the high voltage generator. The head electrode 5 and a lower electrode 6 opposed from below with the patient P interposed therebetween are provided, and different potentials are applied to the lower electrode 6 and the head electrode 5, respectively. Note that the input terminal of the high voltage generator has an electrical contact for turning on and off the voltage from the commercial power source.

  In this embodiment, the backrest portion 7 of the chair 4 is provided so as to be foldable forward (see FIG. 14) with respect to the seat portion 8, and when the potential treatment device 1 is not used, the backrest portion 7 is tilted or lying down. It is configured to be stored in a folded state. Further, in the configuration example of FIG. 1, a foot electrode on which both feet of the patient P are placed is shown as the lower electrode 6, but the patient P is sandwiched at a position below the head electrode 5. As long as the lower electrode is opposed to the head electrode 5, the seat electrode on which the buttocks of the patient P is placed may be used. In this case, the seat electrode is provided in the seat 8 of the chair 4.

  In addition, although the head electrode 5 and the lower electrode 6 are covered with an insulator, a member having an electrical insulating performance is provided between the chair 4 and the floor surface. The lower electrode 6 is connected to the ground terminal of the high voltage generator by a high voltage cord (not shown) so as to have the same potential as the ground.

  The head electrode 5 is disposed so as to be located near the upper part of the head of the patient P, and a support arm 9 extending downward is fixed to the back side of the head electrode 5. In particular, in this embodiment, the head electrode 5 is provided on the rear upper part of the backrest portion 7 of the chair 4 by the lifting device 12 so as to be lifted and lowered.

  The elevating device 12 includes a drive unit 12A such as a motor provided at the lower end of an elevating rail 12B described later, an endless toothed belt (not shown) driven by the drive unit 12A via a gear, A pair of upper and lower pulleys around which a belt is attached, a lifting rail 12B that rotatably supports the pulley and connected to the support arm 9, and a roller (not shown) relative to the lifting rail 12B. And a fixing tool 12C having a substantially U-shaped cross section fixed to the backrest 7 and a portion of the toothed belt (not shown) being pinned to the fixing tool 12C.

  Accordingly, when the toothed belt spanned between the pair of pulleys is rotated forward and backward by the drive portion 12A, a part of the toothed belt is pinned to the fixing member 12C on the backrest portion 7 side. The pulley moves up and down. As a result, the support arm 9 and the head electrode 5 are configured to move up and down with respect to the backrest 7 together with the pulley, the lifting rail 12B, and the drive unit 12A.

  Furthermore, as shown in FIG. 2, guide means for smoothly guiding the lifting operation of the lifting rail 12B is provided on both the left and right sides of the lifting device 12. The guide means includes a pair of left and right guide rails 10 and 10 fixed to the rear upper portion of the backrest portion 7, and guide portions 11 and 11 fitted to the guide rails 10 and 10 so as to be slidable in the vertical direction. Consists of.

  The guide portions 11 and 11 are left and right side portions of a cover body 19 that covers the entire lifting device 12. 4, 5, 8, and 11 show a state when the cover body 19 is removed.

  The lower part of the support arm 9 is pivotally attached to the upper part of the elevating rail 12 </ b> B via the horizontal shaft 13. Here, the support arm 9 is configured to be able to turn about 135 degrees continuously or stepwise on the rear surface side of the backrest 7. Thus, as shown in FIG. 4, the head electrode 5 is not only movable in the vertical direction (longitudinal direction) with respect to the backrest portion 7, but also tilted in the direction around the horizontal axis (folding operation). ) Is possible.

  In FIG. 5, 15 is a cable for high voltage (for example, 4500 volts), and 16 is a cable for low voltage (for example, 12 volts). The upper end portion of the high voltage cable 15 is connected to the head electrode 5, and the upper end portion of the low voltage cable 16 is connected to a power display lamp 22, an optical sensor 18 and the driving portion 12A described later. . The high voltage cable 15 and the low voltage cable 16 are arranged on the mounting plate 17 fixed to the inner surface side of the cover body 19 so as to extend in parallel in the vertical direction with a predetermined interval.

  Further, in FIG. 5, the lower end side lead portion 15 a of the high voltage cable 15 extends downward from the lower portion of the mounting plate 17 and is connected to the high voltage generator. Further, the lower end side drawing portion 16a of the low voltage cable 16 extends in the lateral direction from one side portion of the mounting plate 17 and is connected to a control portion (not shown). Therefore, the high voltage cable 15 and the low voltage cable 16 are wired at positions separated from each other by a predetermined distance or more on both the left and right sides of the lifting device 12 that lifts and lowers the head electrode 5.

  The drive unit 12A is electrically connected to a control unit (not shown) for controlling operation / stop of the drive unit 12A. Furthermore, a head position detection unit for detecting the height position of the head of the patient P is electrically connected to the control unit.

  Here, an optical sensor 18 is used as the head position detection unit. The signal detected by the optical sensor 18 is sent to the control unit, and the operation of the drive unit 12A is controlled to start and stop by a command signal from the control unit based on the signal. As a result, the head electrode 5 is automatically adjusted to a height that matches the height position of the head of the patient P.

  As shown in FIGS. 6 and 7, a lamp window 20 and a sensor window 21 are formed vertically on the upper front side of the support arm 9, and each of the windows 20, 21 has, for example, an LED element. A power indicator lamp 22 and an optical sensor 18 are directed toward the patient P in front. As described above, a voltage of 12 volts, for example, is supplied to the power indicator lamp 22 and the optical sensor 18 via the low voltage cable 16.

  The power indicator lamp 22 and the optical sensor 18 are detachably attached to an upper lamp recess 24 and a lower sensor recess 25 provided on an upper and lower step fixing member 23, respectively. The fixing member 23 is attached to the front surface of the support arm 9. It is fixed to the part.

  A transparent insulating member 27 is provided between the power indicator lamp 22 and the optical sensor 18 and the front portion of the support arm 9, and the transparent insulating member 27 is made of a transparent or translucent synthetic resin that can transmit light. The transparent insulating member 27 has a function of preventing a discharge phenomenon from occurring between the power indicator lamp 22 and the optical sensor 18 and the patient P.

  Further, the cross-sectional shape of the transparent insulating member 27 in a side view is formed so as to have two steps of upper and lower steps. The portions of the transparent insulating member 27 corresponding to the power display lamp 22 and the optical sensor 18 are vertical surface portions located at the same height as the windows 20 and 21, and light emitted from the power display lamp 22 and the optical sensor 18. Advances horizontally toward the patient P at a right angle to the vertical surface.

  In other words, by forming the transparent insulating member 27 in a side-view shape with a stepped shape, the transmission efficiency of the emitted light from the power display lamp 22 and the optical sensor 18 is improved and the rigidity of the transparent insulating member 27 itself is increased. is doing. Furthermore, the front surface (left surface in FIG. 6) of the upper and lower ends of the transparent insulating member 27 is attached to the back surface (right surface in FIG. 6) of the support arm (attachment member) 9 in a superposed manner. The lengths L1 and L2 of the overlapping portions on the upper side and the lower side of the transparent insulating member 27 are set so that the creeping distance of the transparent insulating member 27 is longer than a predetermined value. Here, L1 = 7.5 mm, L2 = 12.8 mm.

  In this way, by increasing the lengths L1 and L2 of the overlapping portions of the transparent insulating member 27 and the support arm 9 so that the creepage distance of the transparent insulating member 27 is equal to or greater than a predetermined value, the head of the subject P is treated. The electrical insulation performance between the power supply indicator lamp 22 and the optical sensor 18 is remarkably increased.

  The potential treatment device 1 configured as described above generates a high voltage with the high voltage generator, and generates a high electric field between the electrodes 5 and 6 by applying the high voltage between the head electrode 5 and the lower electrode 6. Let Then, the potential treatment is performed in a state where the patient P is set to a high potential and is located in the region of the high electric field.

  In actual potential treatment, before the power supply of the potential treatment device 1 is set to ON, as shown in FIG. 8, the lower end side L-shaped portion 26 of the elevating rail 12 </ b> B connected to the lower portion of the support arm 9 is connected to the backrest portion 7. It is located at the upper limit height close to the fixture 12C fixed on the rear side. A limiter (not shown) that operates when the fixing tool 12C approaches within a predetermined distance is attached to the lower end and the upper end of the elevating rail 12B, and the drive unit 12A is stopped by an operation signal of the limiter. Thus, the upper limit position and the lower limit position of the lifting rail 12B are determined.

  Now, it is assumed that the patient P seated on the seat 8 of the chair 4 operates the remote control switch at hand to set the power supply of the potential treatment device 1 to ON. Then, the power display lamp 22 is turned on and the optical sensor 18 is activated so that the position can be detected. At the same time, the drive unit 12A of the elevating device 12 is activated, and the entire elevating device 12 including the drive unit 12A and the elevating rail 12B is moved down along the guide rails 10 and 10.

  Then, as shown in FIGS. 9 to 11, the head electrode 5 moves downward with respect to the backrest portion 7, and eventually the sensing area R of the optical sensor 18 that is oriented substantially horizontally becomes the head (head) of the patient P. Move to a level that matches the top of the part (see FIG. 12).

  As a result, the height position of the head of the patient P in the sitting posture is automatically and accurately detected by the optical sensor 18. After the height position detection signal is transmitted to the control unit, an operation stop command signal is sent from the control unit to the drive unit 12A based on the signal, and the operation of the drive unit 12A is stopped. At the same time, the operation of the optical sensor 18 is stopped.

  Thus, the head electrode 5 is aligned at a height commensurate with the head height of the patient P. Therefore, the person to be treated P only sits on the chair 4, and the height of the head electrode 5 is automatically adjusted to the optimum level, and the best potential treatment effect can be achieved.

  In addition, after completion | finish of electric potential treatment, the to-be-treated person P operates a remote control switch and turns off the electric power of the electric potential treatment apparatus 1. Then, the power display lamp 22 is turned off, and at the same time, the entire lifting device 12 including the driving unit 12A and the lifting rail 12B is raised along the guide rails 10, 10 via the driving unit 12A of the lifting device 12. Then, it moves to the original height position before use and stops (see FIG. 8).

  Here, the height of the head electrode 5 is adjusted so that the distance between the top of the patient P and the head electrode 5 is 11.5 cm. This is because a stable therapeutic effect can be obtained even if the distance between the patient P and the head electrode 5 varies somewhat after the height of the head electrode 5 is adjusted. That is, the present inventor has found that the induced current value flowing around the neck of the patient P is substantially constant when the distance between the top of the patient P and the head electrode 5 is 10 to 13 cm. Then, by adjusting the height position of the head electrode 5 so that the distance between the top of the patient P and the head electrode 5 is 11.5 cm, an error or the like occurs in the adjustment position, and then the treatment is performed. Even if the head of the person P moves and the distance between the head of the person to be treated P and the head electrode 5 varies somewhat, the distance between the head of the person to be treated P and the head electrode 5 is 10 to 13 cm. Fits to the extent. For this reason, the value of the induced current flowing around the neck is kept almost constant, and a stable therapeutic effect can be obtained.

  Measurement data indicating this is shown in FIGS. This measurement data is that the voltage applied by the high voltage generator is 15000 volts, the distance between the top of the patient P and the head electrode 5, the value of the induced current flowing through the neck of the patient P and the induced current density (induction This is data showing the relationship with the current value divided by the horizontal cross-sectional area of the neck. As is clear from this data, when the distance between the top of the subject P and the head electrode 5 is 11 cm and 12 cm, the induced current values are the same, and when the distance is 10 to 13 cm, the induced current value is the same. It can be seen that is almost constant. This is the same tendency even if the voltage applied by the high voltage generator is changed. The induced current value is constant when the distance between the top of the subject P and the head electrode 5 is 15 cm or more. This is the function of the head electrode 5 as an electrode when the distance is 15 cm or more. This shows that (effect) is attenuated.

  By the way, in the present embodiment, the height of the head electrode 5 is adjusted so that the distance between the top of the subject P and the head electrode 5 is 11.5 cm which is a median value of 10 to 13 cm. . This is so that even if the distance between the head of the patient P and the head electrode 5 increases or decreases, the distance between the head of the patient P and the head electrode 5 can be kept within about 10 to 13 cm. is there. On the other hand, for example, when the head of the patient P tends to drop during the treatment, that is, when the distance between the top of the patient P and the head electrode 5 tends to increase, The height may be adjusted to 10.5 cm. Thereby, even if the head of the to-be-treated person P falls during the treatment, the distance between the top of the to-be-treated person P and the head electrode 5 can be reduced to about 13 cm.

  Furthermore, in this embodiment, the inclination angle of the backrest portion 7 is variable (reclining type), and the height of the head electrode 5 is adjusted when the inclination angle of the backrest portion 7 is changed. That is, a driving device (not shown) that changes the inclination angle of the backrest 7 and the lifting device 12 based on the optical sensor 18 are linked. Then, when the driving device for the backrest 7 is activated, the height position of the head of the patient P is detected by the optical sensor 18, and the lifting device 12 is driven based on this detection signal, and the height of the head electrode 5 is increased. Is adjusted. Thus, since the height of the head electrode 5 is adjusted when the inclination angle of the backrest portion 7 changes, even if the inclination angle of the backrest portion 7 changes and the position of the head of the patient P changes, The distance between the head of the treating person P and the head electrode 5 is optimally maintained. Moreover, it is not necessary to manually adjust the height of the head electrode 5 each time the inclination angle of the backrest portion 7 changes. It should be noted that the height adjustment of the head electrode 5 may be performed when the inclination angle of the backrest portion 7 is changed, and the height of the head electrode 5 is simultaneously changed while the inclination angle of the backrest portion 7 is changed. Adjustments may be made.

  Further, in this embodiment, by arranging the high voltage cable 15 and the low voltage cable 16 on one side and the other side in the left-right width direction sandwiching the lifting device 12 that is the lifting means of the head electrode 5, respectively. Both cables 15 and 16 are disposed at locations separated from each other.

  Therefore, even when the potential difference between the high voltage cable 15 and the low voltage cable 16 is large, it is possible to effectively suppress the occurrence of discharge between the cables 15 and 16. As a result, it is possible to prevent the occurrence of a discharge phenomenon between the cables 15 and 16, and to prevent the ignition accompanying the discharge phenomenon and the damage to the peripheral members.

  Here, during use of the potential treatment device 1, the body potential of the patient P in the electric field is, for example, 4500 volts, and the potentials of the optical sensor 18 and the power display lamp 22 are, for example, 12 volts. For this reason, if both of them are too close due to these potential differences, a discharge phenomenon may occur.

  However, in this embodiment, since the transparent insulating member 27 is provided between the head of the patient P, the power display lamp 22 and the optical sensor 18, a discharge occurs between them. Is effectively suppressed. Thereby, during the potential treatment, the electric field distribution between the electrodes 5 and 6 and the patient P is not affected, and the electric field strength is not reduced by the discharge, and sufficient potential treatment is performed. Can receive.

  In particular, as shown in FIG. 6, the transparent insulating member 27 is formed by increasing the length L1 and L2 of the overlapping portion with the support arm 9 so that the creepage distance of the transparent insulating member 27 is not less than a predetermined value. Yes. For this reason, compared with what formed the creepage distance less than predetermined value, the insulation performance between the head of the to-be-treated person P, the power supply indicator lamp 22 and the optical sensor 18 increases remarkably, and the discharge between these increases. Can be more reliably prevented.

  Further, since the lower side support arm 9 of the head electrode 5 is configured to be able to tilt and fall to the rear side of the backrest portion 7 of the chair 4, when the potential treatment device 1 is not used, as shown in FIG. The support arm 9 can be stored in a folded state so as to be substantially parallel to the rear surface portion of the backrest portion 7. Therefore, the head electrode 5 can be compactly accommodated in a state that does not get in the way when the potential treatment device 1 is moved or packed.

  Further, since the backrest portion 7 of the chair 4 is configured to be tiltable forward with respect to the seat portion 8, when the potential treatment device 1 is not used, the backrest portion 7 is seated as shown in FIG. 14. It can be stored in a folded state so as to be close to the upper surface of the portion 8. Thus, the backrest portion 7 of the chair 4 can be accommodated in a more compact state so as not to get in the way when the potential treatment device 1 is moved or packed. Therefore, the packaging and transportation of the potential treatment device 1 can be more easily performed.

  In the above embodiment, the power on / off operation of the potential treatment device 1 is configured to be performed by the remote control switch. However, this operation switch can be operated by the armrest 3 or its vicinity as long as the patient P seated on the chair 4 can operate at hand. It is also possible to provide it at a location. In addition, in the specification in which a person other than the patient P performs the power on / off operation, it is not necessary to arrange an operation switch near the patient P.

  In addition, although the optical sensor 18 is used as the head position detection unit, the present invention is not limited to this as long as the height position of the head of the patient P can be automatically detected. Further, in the above embodiment, as a means for raising and lowering the head electrode 5, an elevating mechanism of a system for rotationally driving a toothed belt has been described as an example, but should not be limited to this, for example, a screw driving system, a rack -Needless to say, other known lifting mechanisms such as a pinion gear system can be appropriately employed.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified one.
