Problems solved by technology

[0005] The problem to be solved by the present invention is to solve the defects of existing products: because the distance between the electrode pads and the parts of the human body is different, the impedance of the access will be different, and the current change will be caused by using the traditional transformer amplification method.

Embodiment Construction

[0022] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and technical solutions.

[0023] figure 1 It is a connection schematic diagram of each component circuit module of the intermediate frequency therapeutic apparatus system of the present invention. The system consists of a control module, a waveform modulation module, an intensity adjustment module, a constant current amplification module, a display module, an alarm module, a storage module, a detection feedback module and a power supply module.

[0024] Among them, the control module is the control part of the system, which controls the voltage amplitude of the input signal of the digital-to-analog converter in the waveform modulation module to realize the amplitude modulation of the high-frequency square wave signal; the digital-to-analog converter of the control intensity adjustment module control the sound of the buzzer of the alarm m...

Abstract

The invention discloses a constant-current output intermediate-frequency therapeutic instrument system, belongs to the field of medical rehabilitation treatment equipment, and relates to a system capable of realizing constant-current output of an intermediate-frequency therapeutic instrument. The system consists of a control module, a waveform modulation module, an intensity adjustment module anda constant-current amplification module, and generation, modulation, intensity adjustment, amplification and output of a carrier wave are realized. The input end of the control module is connected with a detection feedback module, and the output end of the control module is respectively connected with a display module, an alarm module and a storage module; and the control module is also connectedwith the waveform modulation module and the intensity adjustment module. The waveform modulation module adopts amplitude modulation and multiplies a high-frequency carrier signal with a low-frequencymodulation signal, so that the amplitude of the high-frequency signal changes along with the change of the amplitude of the low-frequency signal. By the system, constant-current output under the control of a single chip microcomputer is realized, and the safety of patients is ensured. The system has a storage function, and facilitates recording; and the practicability and convenience of the therapeutic instrument are improved.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation treatment equipment, and relates to a system capable of realizing constant current output of an intermediate frequency treatment instrument. Background technique [0002] Medium-frequency electrotherapy is currently widely used in clinical practice. Through the modulation of various low-frequency electrical signals, specific parts are stimulated, which can relieve pain, promote local blood circulation, exercise skeletal muscles and increase the tension of smooth muscles. [0003] After market research, most of the intermediate frequency therapeutic instruments in the domestic market are intermediate frequency electrical products with a single waveform, which has a single curative effect, which will cause users to adapt to a single signal after long-term use, and it is difficult to adapt to multiple treatment needs. More importantly, the therapeutic device should have corresponding safety prot...
