Circuit of electro-therapeutic apparatus zero in stabbing pain and longest in electricity saving time

Abstract

Disclosed is a circuit of an electro-therapeutic apparatus zero in stabbing pain and longest in electricity saving time. The circuit of the electro-therapeutic apparatus includes a voltage conversion module, a rectifying module, a voltage stabilizing module, an input module, a display module, a constant-current constant-voltage module, an amplifying module, or a constant-current constant-voltage module, a pulse step-up module and an output module. The voltage conversion circuit module, the rectifying circuit module and the voltage stabilizing circuit module are serially connected and then finally connected with the step-up module. The display circuit module and the constant-current constant-voltage module are connected in parallel to a control module and the control module is controlled by the input module. The constant-current constant-voltage module, the amplifying module, the constant-current constant-voltage module, the step-up module and the output module are connected sequentially. An infrared generator module and the constant-current constant-voltage module are connected in parallel and sent out by the amplifying circuit. The constant-current constant-voltage modules are added in the electro-therapeutic-apparatus circuit on the basis of a traditional intermediate-frequency electro-therapeutic apparatus so that signal jitter which happens when pulse signals are enhanced is effectively controlled and stable transition is realized and thus when momentary high voltage and intense current enter the constant-current constant-voltage modules, a buffer period is experienced.

Description

technical field [0001] The invention relates to an electronic circuit, in particular to an electrotherapy instrument circuit with no stinging pain and the longest electricity retention time. Background technique [0002] When the pulse current passes through the affected part of the human body, it can stimulate acupoints, relax blood vessels, and relieve fatigue. The existing intermediate frequency electrotherapy device follows this principle, adopts the principle of no constant current and constant voltage protection amplification, and directly acts on the human body through electrodes to act. Stimulate acupuncture points, relieve muscle tension, and promote local metabolism. However, this traditional medium-frequency electrotherapy instrument has limited therapeutic effect, strong tingling sensation at the site of action, weak penetrating ability, and easy dependence. When the sticky electrode is used repeatedly, the sticky electrode is easy to fall off. When the sticky e...

However, this traditional medium-frequency electrotherapy instrument has limited therapeutic effect, strong tingling sensation at the site of action, weak penetrating ability, and easy to produce dependence

When the sticky electrode is used repeatedly, the sticky electrode is easy to fall off. When the sticky electrode is not close to the skin, the human body feels a particularly strong needling sensation, which is difficult for patients to accept and is prone to danger, thus affecting the therapeutic effect.
