In the above-mentioned checker for a high-frequency treatment device, whether the electromagnetic wave (oscillation signal) emitted by the high-frequency treatment device is received by the antenna coil and the battery voltage of the high-frequency treatment device is high, that is, charging is required. This is a method of determining whether or not. Therefore, it is necessary to dispose the antenna coil on the front surface side of the checker body, which requires a large space and cannot achieve miniaturization. Further, since it is a method of detecting a weak oscillation signal, it is necessary to provide an amplifier circuit in addition to the detection circuit, which has a disadvantage that the circuit configuration becomes complicated and the cost becomes high.

An object of the present invention is to provide a checker for a therapeutic device which solves the above problems, can be miniaturized, and has a simple circuit configuration and is inexpensive.

[0005]

In order to achieve this object, the therapeutic device checker of the present invention has the following structure. The therapeutic device checker has a built-in power supply circuit and a charging terminal on the upper surface, and a lower case that can be attached to and detached from the upper surface of the lower case. It comprises a fixed frame part for fitting a therapeutic device, and an upper lid case provided with a voltage detection terminal in which the electrode of the therapeutic device and the upper part are in contact with each other and the lower part is in contact with and separated from the charging terminal in the fixed frame part. Is characterized by.

In the checker for a therapeutic device having such a structure, the upper lid case is attached to the lower case so as to be separable by a hinge, for example. When judging the number of batteries in the treatment device (judging the operation confirmation of the treatment device), slightly lift the upper lid case. This separates the voltage detection terminal of the upper lid case from the charging terminal of the lower case. In this state, the treatment device is fitted into the fixed frame portion of the upper lid case. At this time, the electrode of the treatment device contacts the voltage detection terminal, and the battery voltage (output voltage) is directly detected by the voltage detection circuit.
Then, for example, if there is no need for charging (if normal operation can be confirmed), the fact is notified by lighting the LED or the like. If the battery output voltage of the treatment device is low and it is necessary to charge the battery, the upper lid case is brought into contact with the upper surface of the lower case in this state. As a result, the voltage detection terminal comes into contact with the charging terminal. That is, the electrode of the treatment device is connected to the charging terminal via the voltage detecting terminal. Therefore, the battery of the treatment device is charged by the power supply circuit.

FIG. 5 is a block diagram showing an example of the circuit configuration of the high frequency treatment device 4. As is well known, in the high-frequency treatment device 4, a charging battery is connected in parallel between the electrodes 41 and 42, the oscillation circuit 43 is driven by the charging battery, and an electromagnetic wave is generated from the generating coil (antenna) 44. ..

With the checker for a high-frequency treatment device having such a configuration, when determining the number of batteries of the high-frequency treatment device 4 (determining the operation confirmation of the high-frequency treatment device), the upper lid case 2 is slightly lifted. As a result, the voltage detection terminals 22 and 23 of the upper lid case 2 and the charging terminals 31 and 32 of the lower case 3 are separated from each other. In this state, the high frequency treatment device 4 is fitted into the fixed frame portion 21 of the upper lid case 2. At this time, the electrode 41 of the high frequency treatment device 4 is connected to the voltage detection terminal 2,
The electrodes 42 contact the ground terminals 23, respectively, and the battery voltage (output voltage) is directly detected by the voltage detection circuit 25. Then, for example, if there is no need for charging (if normal operation can be confirmed), the fact is notified by turning on the LED 24 or the like. If the output voltage of the battery of the high frequency treatment device 4 is low and the battery needs to be charged, the upper lid case 2 is brought into contact with the upper surface of the lower case 3 in this state. As a result, the voltage detection terminal 22 contacts the charging terminal 31 and the ground terminal 23 contacts the ground terminal 32. That is,
The electrodes 41 and 42 of the high frequency treatment device 4 are the voltage detection terminals 2
It is connected to the charging terminals 31, 32 via 2, 23. Therefore, the battery of the high frequency treatment device 4 is charged by the power supply circuit 33.

Thus, the high-frequency treatment device 4 is attached to the upper lid case 2.
Charging and voltage detection (operation check) can be executed by a simple operation in which the upper case 2 is attached to and detached from the lower case 3 in a state where the battery is fitted, and charging work and voltage detection work (from the high frequency treatment device) The work of receiving the oscillating signal of 1) and the changeover switch etc. are completely unnecessary.

The charging work and the voltage detection work can be executed by a simple operation of bringing the upper lid case into and out of contact with the lower case. Further, since the output voltage of the treatment device is directly detected, it is possible to confirm whether or not the treatment device needs to be charged only by the voltage detector. Therefore, unlike the conventional case, the receiving antenna coil is not required, the checker body can be downsized, and a checker with a simple circuit configuration and an inexpensive checker can be provided.
