Problems solved by technology

Since the treatment waveform is solidified in the circuit of the product, the types of treatment waveform changes that the user can obtain, that is, the treatment prescription is less, and it is impossible for the user to update and communicate by himself, which greatly limits the treatment range of the electrotherapy instrument. The circuit structure is complex, and it is difficult to generate complex treatment waveforms

Embodiment Construction

[0010] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0011] figure 1 Among them, the data communication interface JP1 of this embodiment adopts a USB interface, which can be connected with the USB socket of a PC through a USB connection line. Microprocessor to complete, the chip contains USB transceiver, serial port interface engine, and enhanced version 8051 processor, can directly use 8051 instructions, can not only complete the USB interface function between the same PC, but also complete the device Various control functions in . The USBD+ and USBD- of the microprocessor CY7C64613 are respectively connected to the D+ and D- leads in the USB socket (JP1), and the "digital / analog conversion" circuit can use the 8-digit / analog conversion circuit DAC0800. To the PA0-PA7 of CY7C64613, the analog output of DAC0800 is a current output, which can be converted into a voltage output by the OP amplifier. The output voltag...

Abstract

The electrotherapeutical instrument matching with PC includes output electrode, amplifier circuit, microprocessor, etc. and features its communication interface connected to PC, interface circuit and A / D converter circuit connected together. The present invention makes it possible for the user to select different treating waveform by means of the corollary software and to download new treating scheme from web sit for even wide use. In addition, the present invention uses the digital communication interface directly without occupying the sound card and affecting the normal operation of PC.

Description

technical field [0001] The invention relates to a medium-low frequency electrotherapy instrument in the field of medical and health care equipment. Background technique [0002] Medium and low frequency electrotherapy instrument (including medium frequency electrotherapy instrument and low frequency electrotherapy instrument, also including analog massage instrument and some weight loss instruments using electric pulse stimulation, the principle is the same), is an electronic device used for medical care, the principle is The electronic circuit synthesizes and produces medium and low frequency pulse waves, which are amplified and output to the electrodes installed on the body of the person being treated, and the therapeutic and health care effects are achieved by stimulating the human body with electric pulses. The therapeutic and health care effects and range depend on the medium and low frequency pulse wave waveforms The change. [0003] Existing medium and low frequency ...
