Computer electrotherapy fk998-ga(2) eight channels pulse current ion importer

Fk998-ga(2) is a medical device for physiotherapy and applies to large- and medium-sized hospitals, community medical institutions and rehabilitation institutions. Using microcomputer control techniques, it consists of medium-sized, large-scale integrated circuits with four synchronized or walk-out export channels, eight output ports and display functions。
99 specific multi-step prescriptions for machine memory. They are developed by physiotherapy specialists based on different uses. Of these, 20 are routine multistep treatment prescriptions, 16 are audio current therapy prescriptions, 23 are frequency current therapy prescriptions in the swirl and 40 are frequency current therapy prescriptions in the pulse. The doctor chooses the prescription for treatment depending on the patient's condition. When a prescription is selected, the instrument is activated and the frequency current is automatically exported by programme in a series of specified therapeutic effects. Output current size is freely regulated. When the prescription program is finished, the instrument automatically cuts the output current and sends a sound
