<Prior art and its problems> As a biological treatment technique, attempts have been made for a long time to test or treat a living body by applying high frequency energy to the living body. An example of such a high-frequency energy-based biological treatment method is shown in FIG. 4, for example.

Electrode 2
, 3, and a cooler 1 = 1 for protecting the human body 1 from heat generated by the high current 1c of the gold electrode a2.3. The impedance matching device 13 includes a sponge or the like interposed between the electrode and the human body, a matching reactor whose inductance can be changed with a gold adjustment knob, or a matching capacitor whose distance between electrodes can be changed with a U3 adjustment knob. Consists of. The power meter 121 determines whether this impedance matching is performed correctly.
This power meter has two meter displays 17.18t'' as shown in FIG.

The meter display section 17 indicates, for example, the magnitude of incident power, and the meter display section 18 indicates the magnitude of reflected power. And these meter display parts L7. When the deflection amount of both needles L8 exceeds a certain limit, the inductance adjustment knob 15 or 16 is operated to perform proper impedance matching.

In addition, in FIG. 6, reference numeral 19 indicates various operations of the high-frequency heating machine,
Press the push button to make adjustments.

However, with such conventional high-frequency heating machines (8), impedance matching and mismatching can be measured using a power meter.

If the meter display section 17.18 is to be displayed on the screen, the user must constantly or frequently display the meter display section 17. There is a problem.

<Object of the Invention> The present invention has been made by paying attention to such conventional problems, and its purpose is to provide a high-frequency heating machine that provides an audible alarm light when the impedances become mismatched. By solving the above conventional problems, β
Ru.

<Configuration and Effects of the Invention> In order to achieve the above-mentioned object 1c, the present invention includes a high-frequency energy generating means and a method for supplying the energy generated by the high-frequency energy generating means to a living body.
47e-f7: Z*@″P5′″11 high frequency heating machine,
The gist of this is that there are nine alarm bells that can be used to notify an impedance mismatched washer by an audio signal.

For the alarm, a wide variety of sounding devices can be used, including not only those that emit simple alarm sounds, but also those that emit melodic sounds, and even those that use spoken words created by voice synthesis. This alarm sounds when the difference between incident power and reflected power exceeds a predetermined value in a power meter built into the high frequency energy generator.

Therefore, even if the operator of the high-frequency heating machine starts work on the trench or other work where the heating machine was turned on, the above-mentioned audio alarm will notify the operator of the impedance mismatch, so the operator can immediately adjust the matching. It also has the effect of allowing you to perform other work in areas that are somewhat affected by the high-frequency heating machine.

<Explanation of Implementation> Examples of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are diagrams showing one embodiment of the present invention.

The alarm high frequency heating machine according to this implementation sequence has an oscillator 7
, an intermediate amplifier 8 that increases the output from the oscillator 7 by I1g, a power supply L1, a power amplifier 9 that amplifies the output from the source 11, and feeds the output from the power amplifier 9 to the oscillator 7. An output control and protection circuit 10, an impedance matching device 13 that performs impedance matching for high-frequency oscillation signals, an electrode 2.3 that supplies high-frequency energy to the human body 1, and incident power and reflected power to the electrodes 2 and 3. A power meter 12 that monitors
The present invention has the same basic four components as the above-mentioned conventional example in that it consists of a cooler 14 to protect against heat generation due to high current.

However, unlike the conventional example, the high frequency heating machine according to the present embodiment has an alarm circuit 20 connected to the power meter 12,
It also includes a speaker 21 that operates in response to the output of the alarm circuit 20. 9. Impedance matching device 1
3 is the same as explained for the conventional row above, with a sponge etc. interposed between the electrode and the human body, and a matching reactor whose inductance can be changed with the 'A adjustment knob, etc., or the distance between the electrodes can be changed with the adjustment knob. It consists of a FTP31 combined capacitor, etc. Whether this impedance matching is performed correctly is monitored by the power meter 2, which has two meter display sections 17 and 18, as shown in FIG. The meter display section 17 indicates, for example, the magnitude of incident power, and the meter display section 18 indicates the magnitude of reflected power. As shown in FIG. 3, the alarm circuit 20 includes a first buffer amplifier 22 to which incident power is input, a second buffer amplifier 23 to which reflected power is input, and these first and second buffer amplifiers 22. Comparator 26 (!:) compares the outputs from 23 and outputs an activation signal when the difference between the two outputs exceeds a predetermined value. The first and second buffer amplifiers 22 and 23 include variable resistors 24 and 25, respectively.
are connected so that the amplification factors of each buffer amplifier 22 and 23 can be variably set.

Since the U power meter 2 and the alarm circuit 20cD connection are configured as described above, in this high frequency heating machine, it is possible to check whether impedance matching is being performed correctly by looking at the amount of deflection of the needle on the meter display 917.18. Not only can the alarm circuit 20 be activated if the difference between the incident power and the reflected power is such that the amount of deflection of the needle on the meter display section 17, 18 exceeds a predetermined limit and the reflected power is The speaker 21 is then activated to emit sound. Various forms of sound can be considered, such as a 999 alert sound to notify an emergency situation, a melody sound, and even words created by a voice synthesis operation. This can be achieved by incorporating a CMO8-LSI for alarm generation.
