As a result, the purpose of transporting and storing the potential treatment device 1 that can prevent the above effectively can be easily achieved. Note that 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.

Example 1

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 14. 1, 2 and 3 are respectively a front perspective view, a rear perspective view and a side view showing the potential treatment device 1 according to the present embodiment. The potential treatment device 1 is not shown with a potential treatment device 2. It consists of a high voltage generator and a commercial power supply.

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 to which a high voltage of 4500 volts is applied. A partial electrode 5 and a lower electrode 6 opposed from below with the head electrode 5 and the patient P interposed therebetween, and the lower electrode 6 and the head electrode 5 have different potentials, respectively. Is applied. The input terminal of the high voltage generator is an electrical terminal for turning on and off the voltage of the commercial power supply. Has contacts.

[0034] 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 folded down. It is configured so that it can be folded and stored in a tilted or lying down state. Further, in the configuration example of FIG. 1, the lower electrode 6 is sandwiched between the patient P at a position below the force head electrode 5 indicating the foot electrode on which both feet of the patient P are placed. As long as the lower electrode is opposed to the head electrode 5, it may be a seat electrode on which the buttocks of the patient P is placed. In this case, the seat electrode is provided in the seat 8 of the chair 4.

[0035] Although the head electrode 5 and the lower electrode 6 are covered with an insulating material, 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.

[0036] 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 the present embodiment, the head electrode 5 is provided on the back portion 7 of the chair 4 by the lifting device 12 so as to be able to move up and down.

[0037] The elevating device 12 includes a drive unit 12A such as a motor provided at a lower end portion of an elevating rail 12B described later, and an endless toothed belt (not shown) driven by the drive unit 12A via a gear. A pair of upper and lower pulleys around which the toothed belt is stretched, a lifting rail 12B which rotatably supports the pulley and connected to the support arm 9, and a mouth (not shown) with respect to the lifting rail 12B And a fixing device 12C having a substantially U-shaped cross section fixed to the backrest portion 7 and being relatively movable up and down via a pin, a portion of the toothed belt (not shown) is a pin. It has been stopped.

[0038] Therefore, when the toothed belt hung around the pair of pulleys is rotated forward and backward by the drive unit 12A, a part of the toothed belt is pinned to the fixture 12C on the backrest 7 side. Pulley moves up and down relative to fixture 12C. As a result, the support arm 9 and the head electrode 5 as well as the pulley, the elevating rail 12B, and the drive unit 12A are configured to move up and down with respect to the backrest unit 7. Furthermore, on both the left and right sides of the lifting device 12, as shown in FIG. 2, guide means for smoothly guiding the lifting operation of the lifting rail 12B is provided. The guide means includes a pair of left and right guide rails 10 and 10 fixed to the upper rear surface of the backrest portion 7 and a guide portion 11 fitted to the guide rails 10 and 10 so as to be slidable in the vertical direction. , 11 and.

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, FIG. 5, FIG. 8 and FIG. 11 show the state when the cover body 19 is removed.

[0041] The lower portion of the support arm 9 is pivotally attached to the upper portion of the elevating rail 12B via the horizontal shaft 13. Here, the support arm 9 is configured to be able to rotate 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 can be moved in the vertical direction (vertical direction) with respect to the backrest portion 7 and can be 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 of the high voltage cable 15 is connected to the head electrode 5, and the upper end of the low voltage cable 16 is connected to a power indicator lamp 22, optical sensor 18, and the drive unit 12A described later. Yes. 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 15a 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). Thus, the high voltage cable 15 and the low voltage cable 16 are wired at a distance of 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.

[0044] The drive unit 12A includes a control unit for controlling operation / stop of the drive unit 12A.

(Not shown) are electrically connected. Further, 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, as the head position detection unit, an optical sensor 18 is used. With the light sensor 18 The detected signal is sent to the control unit, and the operation of the drive unit 12A is controlled to start / stop by a command signal of the control unit force based on the signal. As a result, the head electrode 5 is automatically adjusted to a height corresponding to the height position of the head of the patient P! /.

[0046] 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 window 20, 21 For example, a power indicator lamp 22 and an optical sensor 18 that also have LED element power face the front side of the patient P to be treated. As described above, a voltage of, for example, 12 volts is supplied to the power indicator lamp 22 and the optical sensor 18 via the low voltage cable 16.

[0047] The power indicator lamp 22 and the optical sensor 18 are detachably attached to the upper lamp recess 24 and the lower sensor recess 25 provided in the upper and lower stepped fixing member 23, respectively, and the fixing member 23 is supported. It is attached and fixed to the front part of arm 9.

[0048] 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 a transparent or translucent synthetic plate that can transmit light. Consists of fat. 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.

[0049] 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 step surfaces. The portion of the transparent insulating member 27 corresponding to the power indicator lamp 22 and the optical sensor 18 is a vertical surface portion located at the same height as each of the window portions 20 and 21, and the output from the power indicator lamp 22 and the optical sensor 18 is the same. The incident light travels horizontally toward the patient P at a right angle to the vertical surface.

[0050] That is, by forming the transparent insulating member 27 in the shape of a step in the side view, the transmission efficiency of the emitted light from the power display lamp 22 and the optical sensor 18 is improved, and the transparent insulating member 27 itself The rigidity strength is increasing. Further, the front surfaces (left surface in FIG. 6) of the upper and lower end portions of the transparent insulating member 27 are overlapped and attached to the back surface (right surface in FIG. 6) of the support arm (attachment member) 9. The lengths LI and L2 of the overlapping portions on the upper side and the lower side of the transparent insulating member 27 are dimensioned so that the creepage distance of the transparent insulating member 27 is longer than a predetermined value. Here, Ll = 7.5 mm, L2 = 12.8 mm is set.

[0051] In this way, the transparent insulating portion 27 is set so that the creepage distance of the transparent insulating member 27 is equal to or greater than a predetermined value. By increasing the length LI, L2 of the overlapping part of the material 27 and the support arm 9, the electrical insulation performance between the head of the patient P and the power indicator lamp 22 and the optical sensor 18 is remarkably increased. Increase.

[0052] The potential treatment device 1 having the above configuration generates a high voltage with a high voltage generator and applies the high voltage between the head electrode 5 and the lower electrode 6 to increase the voltage between the electrodes 5 and 6. Generate an electric field. 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.

[0053] In the 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 L-shaped portion 26 of the lifting rail 12B connected to the lower portion of the support arm 9 is It is located at the upper limit height close to the fixture 12C fixed on the rear side of the leaning portion 7. 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 lifting rail 12B.

By stopping 12A, the upper limit position and the lower limit position of the lifting rail 12B are determined.

[0054] Now, suppose that the patient P seated on the seat 8 of the chair 4 is operated with the remote control switch to turn on the electric potential therapy apparatus 1. Then, the power indicator 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 moves downward along the guide rails 10 and 10.

[0055] 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 force of the optical sensor 18 oriented in the substantially horizontal direction. Move to a level that matches (top of head) (see Figure 12).

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

[0057] Thus, the head electrode 5 is aligned at a height commensurate with the head height of the patient P.

Therefore, the patient P only sits on the chair 4, and the height of the head electrode 5 reaches the optimum level. It can be adjusted automatically to achieve the best potential therapeutic effect.

[0058] After the potential treatment is completed, the patient P operates the remote control switch to turn off the potential therapy apparatus 1. Then, the power indicator 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 and 10 through the driving unit 12A of the lifting device 12. Move to the original height before use and stop (see Fig. 8).

[0059] Here, 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. This is so that 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 has been adjusted. That is, the present inventor has found that the value of the induced current flowing around the neck of the patient P is almost 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. Even if the distance between the head of the patient P and the head electrode 5 changes slightly due to the movement of the head of the person P, the distance between the top of the patient P and the head electrode 5 is 10 to 13 cm. Fits to the extent. As a result, the value of the induced current flowing around the neck is kept almost constant, and a stable therapeutic effect can be obtained.

[0060] Measurement data showing this is shown in Figs. This measurement data shows that the voltage applied by the high-voltage generator is 15000 volts, the distance between the top of the subject P and the head electrode 5, the value of the induced current flowing through the neck of the subject P, and the induced current density ( This is the data showing the relationship with the induced 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 is It can be seen that the value 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 indicates that the function (effect) is attenuated.

[0061] By the way, in the present embodiment, the distance between the top of the subject P and the head electrode 5 is 10 to 13 cm. The height of the head electrode 5 is adjusted to 11.5 cm which is the middle value of. This is to keep the distance between the head of the patient P and the head electrode 5 within about 10 to 13 cm even if the distance between the head of the patient P and the head electrode 5 increases or decreases. is there. On the other hand, for example, when the head of the patient P tends to fall during the treatment, that is, when the distance between the top of the patient P and the head electrode 5 tends to increase, the head electrode 5 The height may be adjusted to 10.5 cm. Thereby, even if the head of the patient P falls during the treatment, the distance between the top of the patient P and the head electrode 5 can be reduced to about 13 cm.

Furthermore, in the present embodiment, the inclination angle of the backrest portion 7 is variable (reclining type), and the height of the head electrode 5 is adjusted by changing the inclination angle of the backrest portion 7. . 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 interlocked. Then, when the driving device of 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 head electrode 5 The height is adjusted. Thus, since the height of the head electrode 5 is adjusted when the inclination angle of the backrest 7 changes, even if the inclination angle of the backrest 7 changes and the position of the head of the patient P changes, The distance between the head of the therapist P and the head electrode 5 is optimally maintained. Further, it is not necessary to manually adjust the height of the head electrode 5 each time the inclination angle of the backrest 7 changes. The height of the head electrode 5 may be adjusted when the inclination angle of the backrest portion 7 is changed. Alternatively, the height of the head electrode 5 is changed while the inclination angle of the backrest portion 7 is changed. You can make adjustments!

[0063] In this embodiment, the high voltage cable 15 and the low voltage cable 16 are arranged 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. As a result, the cables 15 and 16 are arranged 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 damage to peripheral members. Here, during the use of the potential treatment device 1, the potential of the body 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. Since, for example, it is 12 volts, there is a risk that a discharge phenomenon will occur if they are too close due to these potential differences.

[0066] However, in this embodiment, since the transparent insulating member 27 is provided between the head of the patient P, the power indicator lamp 22 and the optical sensor 18, a discharge is generated between them. Is effectively suppressed. As a result, during electric potential treatment, sufficient electric potential treatment is performed so that the electric field strength does not decrease due to the electric discharge that does not affect the electric field distribution between the electrodes 5, 6 and the patient P. Can receive.

In particular, as shown in FIG. 6, in the transparent insulating member 27, the lengths LI and L2 of the overlapping portions with the support arm 9 are increased so that the creepage distance of the transparent insulating member 27 is not less than a predetermined value. Forming. For this reason, the insulation performance between the head of the patient P, the power indicator lamp 22 and the optical sensor 18 is remarkably increased as compared with the case where the creepage distance is less than the predetermined value. Discharge can be prevented more reliably.

[0068] Further, since the lower support arm 9 of the head electrode 5 is configured to be tilted and can be tilted to the rear surface side of the backrest portion 7 of the chair 4, when the potential treatment device 1 is not used, FIG. As shown, 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 accommodated in a state that does not get in the way when the potential treatment device 1 is moved or packed.

[0069] 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, as shown in FIG. 7 can be stored in a folded state so as to be close to the upper surface of the seat 8. Thus, when the electric potential treatment device 1 is moved or packed, the backrest portion 7 of the chair 4 can be accommodated in a more compact state so as not to get in the way. Therefore, the packaging and transportation of the potential treatment device 1 can be performed more easily.

[0070] In the above-described embodiment, the power configured to perform the power on / off operation of the potential treatment device 1 with the remote control switch. This operation switch can be operated by the armrest 3 if the patient P seated on the chair 4 can operate the hand. Alternatively, it can be provided in the vicinity thereof. In addition, treatment It is not necessary to place an operation switch near the patient P if the person other than the person P turns on / off the power supply.

[0071] Further, although the optical sensor 18 is used as the head position detection unit, it is needless to say that 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, as the means for moving the head electrode 5 up and down, in the above-described embodiment, the lifting mechanism of the system that rotationally drives the toothed belt has been described as an example, but should not be limited to this. It goes without saying that other known lifting mechanisms such as a pion gear system can be appropriately employed.

[0072] 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 ones.
