Problems solved by technology

For example, the circuit of the timing control unit is completed by the RC charging and discharging circuit, but once the DC voltage drops, the charging time will be extended, so the time control of the electrical stimulation waveform is very inaccurate
In addition, the adjustment and parameter setting of the system are completed through dial switches and potentiometers, which reduces the flexibility of the system, and the accuracy is not high, quantitative control cannot be achieved, and the parameters used cannot be displayed, which makes clinical practice difficult. Statistics and research are difficult to conduct
Such an adjustment method is also quite difficult and inconvenient for non-professionals, such as patients and medical staff.
In addition, a large number of discrete components increase the possibility of system failure, and the workload of technical maintenance is also very large

Abstract

The present invention relates to extraneous control technology of functional electric stimulation in biomedicine engineering, and is one kind of intelligent electric stimulation controller. The controller consists of LCD display and control panel, power supply and step-up and protecting circuit, monochip computer control unit, EEPROM memory system, program controlled amplitude regulating unit, power amplifier circuit and output interface. The controller together with monochip computer and peripheral device constitutes a complete system to produce, control and output functional electric stimulation waveform of several modes and provide electric stimulation signal of enough power. The electric stimulation signal the controller provides may be connected to various stimulation electrodes for different functional compensating and functional receiving purposes.

Description

technical field [0001] A functional electrical stimulation controller with a single-chip microcomputer and a liquid crystal display relates to an in vitro control technology for functional electrical stimulation in the field of biomedical engineering, and is an intelligent electrical stimulation controller. Background technique [0002] Technology and devices for functional recovery or compensation by electrical stimulation have been reported at home and abroad, such as the British Finetech-Brindley Bladder Control Technology, ("The Finetech-Brindley BladderController: Notes for Surgeons and Physicians", relevant parts in March 1994 ), in the seventies in the 20th century, there were products of electric stimulation urination and just controllers on the market, but there were no patents and electric schematic diagrams. The control method and system of this product are closer to the US patent "Method and System for Controlling Bladder Evacuation" (In...
