Description

The present invention, a high voltage is applied to the human body, relates to potential therapy apparatus for performing treatment by forming an electric field around the human body, in particular, it relates to voltage detector informing detects the electric field formed by the potential therapy apparatus It is.

The electric potential treatment apparatus performs a treatment by applying a high voltage to an insulated human body and utilizing a biostimulation action by an electric field formed around the human body. A subject who is being treated by such a potential treatment device cannot experience the formation of an electric field around the human body. For this reason, a voltage detector for confirming that an electric field is formed around the human body is attached to the potential treatment apparatus.

The voltage detector includes, for example, a tip electrode (end electrode) provided at the tip of the device main body, a hand electrode provided at the grip portion of the device main body, notification means such as a buzzer and LED, and the notification means. And a power supply for starting up. When such a detector is placed in the electric field close to the potential therapy device while pressing the power switch, a voltage is induced in the tip electrode and the hand electrode, and the electric field is generated based on this voltage (potential difference). Detected. And when an electric field is detected, a buzzer will sound or LED will light-emit (for example, refer patent document 1).
Japanese Utility Model Publication No. 62-48360

By the way, the voltage applied to the human body by the electric potential treatment device is in a wide range from several hundred volts to several tens of thousands of volts, depending on the type of the electric potential treatment device and voltage adjustment operation. Accordingly, the intensity and range of the electric field formed around the human body also varies over a wide range depending on the model of the potential treatment device and the voltage adjustment operation. Therefore, the voltage detector as described above, for example, an attempt to detect the electric field while applying a voltage of a few hundred V to the human body, if allowed to close to or contacting the electroscope to the human body, detects the electric field, the notification The means cannot be pronounced. On the other hand, an attempt to detect the electric field while applying a voltage tens of thousands V to the human body, electroscope detects the electric field even from relatively far away from the human body, the notification means would sound like.

That is, the voltage applied by the electric potential therapy apparatus, the detection position by the electroscope and so that the notification position, such as sound-emission are different. And in some cases, the electroscope sounds near the human body, and in other cases, the electroscope sounds at a position that is relatively far from the human body, which makes the patient feel confused or incomprehensible There is a fear. That actually formed properly the electric field around the human body, despite its electric field Detectors are accurately detect whether the electric field is properly formed, or the electric field accurately There is a risk that the patient will feel the question whether it is detected.

Therefore, an object of the present invention is to provide an electric potential analyzer for an electric potential treatment device that can notify a detection result of an electric field when it is brought into contact with a detection object such as a human body of the patient.

In order to achieve the above object, the invention according to claim 1 emits sound, light, or the like, an end electrode provided at an end of the device main body, a hand electrode provided at a grip portion of the device main body. The electric field is detected based on the voltage of the end electrode and the proximal electrode by being provided in a notification means and a power source that activates the notification means, and positioned in the electric field formed by the potential treatment device. In the electric potential treatment device voltage detector that emits sound or light from the notification means, a part of the end electrode protrudes from the device body as a contact portion, and when the contact portion is pressed, the end electrode is The end electrode is movably disposed so that the end electrode turns off the power when the power is turned on and the pressure is released , and the power is turned on / off in the vicinity of the grip portion. A hand switch is provided Said contact portion with a detectable field on the surface of the detection object by pressing the sensing object, and can detect the electric field around the detection object by turning on the hand switch, It is characterized by that.

According to the first aspect of the present invention, when a detector having a voltage detector presses the contact portion of the end electrode against the human body of the person to be treated, the contact portion is pressed and the power is turned on. When the electric field is detected, sound or light is emitted from the notification means. Further, when the contact portion of the end electrode is separated from the body of the patient to be treated, the pressure on the contact portion is released, the power is turned off, and the sound generation from the notification means is stopped. Thus, the detection result of the electric field is notified only when the contact portion of the end electrode is pressed against the human body of the patient. In other words, the notification position by the present analyzer is always the surface of a body to be detected such as the human body of the patient, and the notification position does not change even if the applied voltage by the potential treatment device changes. For this reason, there is no possibility that the patient will feel the question whether the electric field is properly formed around the human body or whether the electric field detector accurately detects the electric field.

In addition , when the voltage detector is brought close to the potential treatment device while the power is turned on by the hand switch, sound or light is emitted from the position where the electric field is detected. Thereby, the area | region (range) of the electric field formed around the to-be-treated person's human body can be grasped. In this way, by switching the power-on operation, it is possible to arbitrarily detect the electric field around or on the surface of the detected object.

  Hereinafter, the present invention will be described based on illustrated embodiments.

FIG. 1 is a plan view (a) and a side view (b) showing a voltage treatment device voltage detector 1 (hereinafter referred to as “ voltage detector 1”) according to an embodiment of the present invention. In the figure, reference numeral 2 denotes an upper case, and reference numeral 3 denotes a lower case. The upper case 2 and the lower case 3 constitute an apparatus main body. Reference numeral 4 is a translucent window, reference numeral 5 is an LED display (notification means), reference numeral 6 is a sound generation window, reference numeral 7 is a hand switch button, reference numeral 8 is a nameplate that also serves as a hand electrode, and reference numeral 9 is a battery. The storage lid, 10 is an end electrode.

  As shown in FIG. 2, a circuit board 11 is accommodated in the apparatus main body. On the circuit board 11, the LED display 5 faces the translucent window 4, and a buzzer 12 (notification means) is provided in the sound generation window 6. It arrange | positions so that it may oppose. Further, a first power switch 13 and a second power switch 14 are disposed at both ends on the circuit board 11. The first power switch 13 is disposed so as to face the hand switch button 7, and the hand switch is constituted by the first power switch 13 and the hand switch button 7. The second power switch 14 is a so-called micro switch, and includes a push button 14a and a leaf spring-like lever 14b. When the lever 14b contacts the push button 14a, the second power switch 14 is turned on. Yes.

  In the vicinity of the second power switch 14, the end electrode 10 is arranged at the tip of the lower case 3 (device main body) as follows. That is, two cylindrical support pins 3 a are provided at the tip of the lower case 3, and the end electrode 10 is formed with a long hole 10 b into which the support pin 3 a is inserted. The end electrode 10 is supported by the support pin 3a in a state where the support pin 3a is inserted into the long hole 10b, and is slidable (movable) in the longitudinal direction of the lower case 3. Further, the positions of the support pins 3 a and the long holes 10 b are set so that the contact portion 10 a which is the tip portion (part) of the end electrode 10 protrudes from the tip of the lower case 3. Further, a leaf spring-like pressing plate 15 is provided between the end electrode 10 and the second power switch 14 so that the end electrode 10 is pressed against the distal end side of the lower case 3 by the pressing plate 15. It has become. When the contact portion 10a of the end electrode 10 is pressed against this pressing force, the lever 14b is pressed via the pressing plate 15 and the second power switch 14 is turned on. When the pressure on the contact portion 10a is released, the end electrode 10 is returned to the front end side of the lower case 3 by the pressing plate 15, and the lever 14b is separated from the push button 14a and the second power switch 14 is turned off. It is what is done.

  The nameplate 8 is disposed in the grip portion 2a of the upper case 2 (device main body), and is made of metal and functions as a hand electrode. Further, as shown in FIG. 1 (a), a hand switch button 7 is provided in the vicinity of the nameplate 8, and when the grip portion 2a is gripped, the nameplate 8 is gripped (contacted). The button 7 can be pressed with a finger. When the hand switch button 7 is turned on / off (pressed / released), the first power switch 13 is turned on / off. In addition, a battery 16 (power source) that activates (lights and sounds) the LED display 5 and the buzzer 12 is housed in the battery housing lid 9.

A schematic block diagram of such a voltage detector 1 is shown in FIG. Reference numeral 17 in the figure denotes an amplifier, which is connected to the battery 16 via the first power switch 13 and the second power switch 14, and further connected to the LED display 5 and the buzzer 12. When the first power switch 13 or the second power switch 14 of the voltage detector 1 is turned on in the electric field, a voltage is induced in the end electrode 10 and the name plate 8, and the potential difference between the two voltages is generated by the amplifier 17. Amplified and the electric field is detected. Then, based on the amplified potential difference, the LED display 5 emits light, and the buzzer 12 emits sound.

Next, the operation of the voltage detector 1 having such a configuration will be described with reference to FIGS.

  In the figure, reference numeral 21 denotes an electric potential treatment device, which has the same configuration as that of a widely used electric potential treatment device. Therefore, detailed description thereof is omitted here, but an outline is as follows. In other words, the chair C, the head cover 23, and the footrest 24 on which the patient C sits are provided. The head cover 23 and the footrest 24 are covered with an insulating material, the ground electrode 23 a is embedded in the head cover 23, and the foot electrode 24 a is embedded in the footrest 24. The ground electrode 23a is grounded via a ground cord, and the foot electrode 24a is connected to a voltage output terminal of a high voltage generating unit (not shown). Then, when the high voltage generating unit is operated and the foot electrode 24a is set to a high voltage, an electric field is generated between the ground electrode 23a, the patient C is brought to a high potential, and the periphery of the human body of the patient C An electric field is formed.

In this way, the electric field can be detected by the voltage detector 1 in a state where the electric field is formed around the human body of the person C to be treated. That is, as shown in FIG. 4, the detector D holds the voltage detector 1 by holding the grip portion 2 a (name plate 8), and presses the contact portion 10 a of the end electrode 10 against the human body of the patient C. As a result, the contact portion 10a is pressed toward the second power switch 14, and the second power switch 14 is turned on as described above. Then, as described above, a voltage is induced in the end electrode 10 by the electric field, and when the electric field is detected based on the potential difference between this voltage and the voltage of the nameplate 8, that is, the ground voltage, the LED display 5 emits light, and the buzzer 12 pronounces. When the contact portion 10a of the end electrode 10 is separated from the human body of the patient C, the pressure on the contact portion 10a is released, the second power switch 14 is turned off as described above, and the LED display 5 The light emission and the sound of the buzzer 12 are stopped.

Thus, the electric field is detected only when the contact portion 10a of the end electrode 10 is pressed against the human body of the patient C, and the detection result is notified. That is, it is assumed that the detection position and the notification position by the voltage detector 1 are always the surface of the body to be detected such as the human body of the person C to be treated, and the applied voltage has changed depending on the model of the potential treatment device 21 and the voltage adjustment operation. However, the detection position and the notification position do not change. For example, when a voltage of several hundred volts is applied to the foot electrode 24a and a relatively weak electric field is formed around the human body of the patient C, or a voltage of several tens of thousands of volts is applied to the foot electrode 24a. Even if a very strong electric field is formed, the detection position and the notification position do not change. For this reason, there is no fear that the patient C may feel the question whether the electric field is properly formed around the human body or whether the electric field detector 1 accurately detects the electric field. That is, the patient C can receive treatment by the potential treatment device 21 without worrying about confusion or puzzling feeling. Similarly, the electric field is detected by pressing the contact portion 10a of the end electrode 10 not only on the human body of the patient C but also on a detection object such as a chair 22 or a wall whose electric field is to be confirmed. Can inform the result.

In addition, as shown in FIG. 5, when the voltage detector 1 is brought close to the potential treatment device 21 with the hand switch button 7 (first power switch 13) turned on, the electric field is detected as described above. The LED display 5 emits light from the set position, and the buzzer 12 sounds. For example, when a voltage of several hundred volts is applied to the foot electrode 24a and a relatively weak electric field is formed around the human body of the person C to be treated, the electric field is detected when approaching or contacting the human body. Then, the LED display 5 emits light. When a voltage of tens of thousands of volts is applied to the foot electrode 24a and a very strong electric field is formed, the electric field is detected from a position relatively far from the human body, and the LED display 5 emits light. To do. As described above, since the detection position of the electric field differs according to the strength of the electric field formed around the human body, the electric field detector 1 can grasp the electric field formation region (range) and the strength.

By the way, in this voltage detector 1, as mentioned above, the hand switch button 7 and the first power switch 13 are provided as hand switches, but this hand switch may be provided as necessary. That is, only the second power switch 14 may be provided, and as described above, the electric field is detected only when the contact portion 10a is pressed against the human body or the like of the patient C, and the detection result is notified. .

Although the embodiment of the present invention has been described above, the specific configuration is not limited to the present embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention. It is. For example, in the present embodiment, the end electrode 10 is disposed at the distal end portion of the lower case 3 (device main body), but the end electrode 10 is disposed at the side end portion (longitudinal direction side) of the lower case 3. You may make it do. Further, the notification means is not limited to the LED display 5 and the buzzer 12, but may be other light emitters or sound generators. Further, not only in the chair-type potential treatment device 21 as described above, but also in a bed-type potential treatment device or the like, the electric field detector 1 can detect the electric field and notify the detection result in the same manner as described above. Of course.
