Problems solved by technology

[0005] Based on this, it is necessary to aim at the situation that the traditional technology can only detect when the electrode impedance is very large (or infinite), and when the electrode impedance increases to a certain extent, it has already caused an increase in the current density flowing through the s

Abstract

The invention relates to an electrical stimulation circuit, a control method of the electrical stimulation circuit, a control device of the electrical stimulation circuit and electrical stimulation treatment equipment. The electrical stimulation circuit comprises an electrical stimulation generation circuit, a detection circuit and a control circuit; the control circuit is connected to the electrical stimulation generation circuit and the detection circuit, the control circuit is used for controlling the electrical stimulation generation circuit to output electrical stimulation pulses to a load, and the amplitude of the electrical stimulation pulse currents is equal to a preset current value; the detection circuit is also connected to the electrical stimulation generation circuit and is used for detecting a voltage value and a current value output to a load by the electrical stimulation generation circuit; and the control circuit is also used for obtaining the impedance value of the load according to the voltage value and the current value output to the load by the electrical stimulation generation circuit, and controlling the electrical stimulation generation circuit to stop outputting the electrical stimulation pulse to the load when the impedance value is not in the preset impedance range. The electrical stimulation circuit can protect the safety of a patient in time and prevent the patient from being stabbed or burnt.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electric stimulation circuit, a control method for the electric stimulation circuit, a control device for the electric stimulation circuit, and electric stimulation treatment equipment. Background technique [0002] Electrical stimulation therapy equipment is suitable for the treatment of various types of pain, muscle dysfunction, etc. Its mechanism of action is that the device outputs a specific pulse current to act on the human body through electrodes. [0003] The output of electrical stimulation can be divided into two ways: constant current output and constant voltage output. As the load of electrical stimulation therapy equipment, the impedance (including contact impedance) of human skin and tissue varies in a wide range, possibly ranging from hundreds of ohms to infinity. If constant voltage output electrical stimulation is used, it can be guaranteed that high...
