Introduction to the FK998-T Computer Medium Frequency Electrotherapy Device

The FK998-T Computer Medium Frequency Electrotherapy Device is a medical device used for physical therapy.

This unit utilizes microcomputer control technology, composed of medium and large-scale integrated circuits, featuring dual-channel output and various display functions.

The device stores 90 specific multi-step program prescriptions, which are developed by physiotherapy experts for different applications. Doctors select the appropriate prescription based on the patient's condition. Once a prescription is chosen and the device is activated, it automatically outputs a series of medium-frequency currents with specific therapeutic effects according to the program. The output current intensity can be freely adjusted. When the prescription program concludes, the device automatically cuts off the output current and emits an audible prompt.
