Description

  The present invention relates to a sequence type low frequency treatment device that applies a low frequency current to an affected part of a human body and performs electrical treatment.

  Japanese Patent Publication No. 8-17824 discloses a low-frequency treatment using a plurality of low-frequency treatment devices each composed of a control unit and a pair of conductors, and synchronizing the outputs of the low-frequency treatment devices. A container system is disclosed.

According to the prior art, when a plurality of low-frequency treatment devices are used, it is possible to provide a low-frequency treatment device that can be easily synchronized and does not cause discomfort to the therapist.
However, in the conventional low-frequency treatment device system having a plurality of pairs of conductors, the output of each conductor pair is always output in synchronism with the same frequency, so the treatment feeling is monotonous.

In particular, when multiple pairs of conductors are placed around a single site and treated, it feels as if they were stimulated by only a single conductor pair, taking advantage of the advantages of wearing multiple pairs of conductors, although the strength increases. There wasn't.
Japanese Patent Application Laid-Open No. 2000-245363 discloses a multi-channel low frequency treatment device that uses a plurality of pairs of conductors and sequentially energizes outputs (voltage values or voltage values) with a time shift from each other. However, the feeling of irritation of the treatment device was poor.
Japanese Patent Publication No.8-17824 JP 2000-245363 A

The problem to be solved is that when a plurality of pairs of conductors of a plurality of channels are arranged around a single site, the feeling of conduction is monotonous and lacks change.
A feature of the present invention is that energization is performed by simultaneously applying power of mutually different frequencies to a plurality of pairs of conductors.
In addition, each of the pair of conductors is continuously supplied with power for treatment without interruption and stimulates the affected area.
Furthermore, each of a plurality of specified different frequencies is regularly moved sequentially to another pair of conductors, and the sense of movement of the stimulation position is strongly obtained.
Furthermore, the position where the stimuli such as “press”, “hit”, “feeling squeezed” changed, and a system that can easily change these unique stimuli (= sense of occurrence) by operating the synchronization setter was constructed. In the point.

The present invention comprises a plurality of output channels (5), the pulse voltage or pulse current output from each output channel (5) is used as a therapeutic stimulus to a person, and the pulse voltage output from each output channel (5) or The sequence of changing the frequency of the pulse current with the passage of time is set in advance, and this sequence is applied to each output channel (5) in the sequence type low frequency treatment device (1) acting in common on all the output channels (5). ) Between the output channels (5) can be changed, or the time relationship between the sequences of the output channels (5) is the same and the frequency between the output channels (5) is the same. It is a sequence type low frequency treatment device characterized by being able to change.
In addition, the sequence is repeatedly executed within one treatment time, and the time relationship in which the sequence between the output channels (5) makes a round is that the output phase differs for each output channel (5) within the round sequence. .
Furthermore, it is possible to select whether the time relationship in which the sequence between the output channels (5) makes a round is different or coincides.
Furthermore, the time relationship in which the sequence between the output channels (5) completes is the same, and the frequency of the pulse voltage or pulse current between the output channels (5) is the same for each output channel (5). A frequency slightly different from the reference frequency is set.

According to the present invention, in the sequence type low frequency treatment device that operates in common on all the output channels 5, it is possible to change the time relationship in which the sequence between the output channels 5 is completed, or to change the output channels 5 The time relationship in which the sequence between them is complete is the same, and the frequency between the output channels 5 can be changed.
The conventional low-frequency treatment device with multiple output channels always outputs pulses of the same frequency synchronously from each output channel, so it is treated by attaching multiple output channel conductors around one treatment site. If you set the sequence of the change of the stimulation frequency for each output channel, the above feeling of change can be obtained, but it takes time to set up and is difficult to use. There were problems, but I was able to solve these problems.
In other words, since the frequency of the output for stimulating the affected area is different, there is no monotony and the change is large, giving a colorful and complex feeling, and “habituation” hardly occurs, which is convenient.
The frequency change sequence output from each output channel 5 is the same over each output channel 5, and the time relationship for executing the sequence of each output channel 5 can be easily set or changed, which is convenient. is there.

  In the present invention, the sequence is repeatedly executed within one treatment time, and the time relationship in which the sequence between the output channels 5 makes a round is different in the phase of the output for each output channel 5 in the round sequence. According to this configuration, the sequence is executed repeatedly, and the phases in the one-round sequence are different. Therefore, it is easy to understand and easy to set, and is convenient.

  Moreover, it is easy and convenient to mix a continuous feeling of stimulation (= muscle contraction feeling, itching feeling) and a feeling of tapping.

  In the present invention, it is possible to select whether the time relationship in which the sequence between the output channels 5 makes a round is different or coincides. According to this configuration, it is possible to select either a phase having a different phase in a circuit that makes a round or a phase having a matching phase in a circuit that makes a round, and it is easy to use properly.

  The time relationship in which the sequence between the output channels 5 according to the present invention makes a round is the same, and the frequency of the pulse voltage or pulse current between the output channels 5 is the reference frequency for each output channel 5. The sequence is a sequence in which the frequency increase / decrease value for each output channel 5 is fixed to the initially set value and changes.

  According to this configuration, since there is a slight frequency difference in the output for each output channel 5, it is possible to obtain a strong sense of frequency change, and further, interference of stimuli due to the frequency difference in each output channel 5. A feeling can be obtained and it is convenient.

  The purpose of improving the feeling of energization when multiple pairs 6 of multiple channels 5 are arranged around a single site is to make it possible to change the time relationship that the sequence between the output channels 5 makes a round by different sequences. And realized.
