Living body stimulating apparatus

Abstract

A living body stimulating apparatus capable of giving extensive therapeutic effects and softer feeling of stimulation. Rectangular wave pulse groups S containing a plurality of pulse density modulated higher frequency components or on-pulses than a rectangular wave pulse are applied repeatedly from conductor elements 24 to a human body. As a human body has a capacitive impedance, softer stimulation can be applied to the human body as compared with a rectangular wave having the same current and frequency. Furthermore, a pause period between on-pulses is varied by a stimulus generator means 8, so that a charging current to an equivalent electrostatic capacity of a human body is supplied little by little so as to slowly increase a charged quantity. As a result, cenesthesia of softer stimulation can be obtained.

Description

technical field [0001] The present invention relates to a living body stimulation device in which a guide needle with built-in electrodes is brought into contact with a living body, and a current is passed from the guide needle to the living body to generate stimulation. Background technique [0002] Conventional biostimulators flow low-frequency pulse current output from a signal generator to a guide needle through an affected area to perform treatments such as nerve therapy. For example, Patent Document 1 discloses a biostimulation device in which the user switches the stimulation signal output from the output circuit to the human body as a living body to a direct current output every positive pulse period by operating a switching operation switch. Intermittent pulses, AC intermittent pulses that output a rectangular wave pulse train composed of positive pulses and negative pulses in each cycle, one of the alternating intermittent pulses that output positive pulses and neg...

Problems solved by technology

[0011] In the above reference document 2, PWM modulation is used to gradually increase or decrease the width of each conduction pulse that constitutes the rectangular wave pulse train, and the positive and negative pulse trains of the rectangular wave are alternately provided to the human body, which is generated by the capacitive nature of the human body capacitance. Deformation, the stimulation signal is formed into a low-frequency approximate sine wave waveform, and a soft stimulation can be obtained. However, during the period of generating the rectangular wave pulse train, the width of each conduction pulse is variable within 10 μ ~ 60 μ, for example, if the conduction If the pulse width is particularly wide, the charging amount relative to the equivalent electrostatic capacity of the human body will rise sharply, and there is dissatisfaction that it is difficult to obtain a soft stimulation feeling.
