Vessels are disclosed. Further, Japanese Patent Laid-Open No. 5-115565 discloses a low-frequency treatment device that generates an electrical stimulation pulse having an arbitrary degree of stimulation at an arbitrary time by appropriately changing the pulse width and the pulse interval.

These disclosed low-frequency therapeutic devices are devices for repeatedly outputting an electric pulse for giving a stimulus to a human body, with a predetermined basic waveform at a constant cycle. The speed of stimulation is realized by changing the output cycle, the strength of stimulation is changing the output voltage, and the feeling of stimulation is realized by changing the shape of the basic waveform. Further, in the case of the automatic course, this periodic output is divided into blocks for each basic waveform, and the blocks are patterned and output.
