An Intermediate Frequency Therapeutic Apparatus System with Constant Current Output

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...
