Pre-treatment precautions
Remove the metal products such as watches, keys, jewelry, etc. from the patient. Make the effective electric field as far as possible to avoid metal objects in the body, such as contraceptive rings, steel plates and dowel pins in the body of patients with bone fractures. The patient can not lie down, sit on a metal bed metal chair for treatment, should lie down, sit on a wooden or plastic bed, chair for treatment. The patient's intimate clothing should be able to absorb water (nylon, chemical fiber clothing is not good at absorbing water), so as to avoid the accumulation of sweat when sweating, and the electromagnetic field intensively in the place of sweat to cause burns. Plaster bandages do not prevent treatment, but wet dressings must be removed.Precautions in the treatment
The thickness of the pad is tuned to maximize the output current is appropriate, this time the highest efficiency of the output power of the device, the most conducive to prolonging the life of the FU811 tube. The thicker the pad, the better the thermal effect on the deep tissue. In the use of inappropriate thickness of the pad, did not find the best tuning point when the treatment, will shorten the life of the FU811 tube; in this case, by increasing the output gear to improve the output current, will greatly shorten the life of the FU811 tube, and even burn the FU811 tube very quickly. In the case of not affecting the therapeutic effect, the "staggered machine" recommended output selection to use 1 gear, 3, 4 gear as little as possible; "continuously adjustable machine" as far as possible not more than 100ma, so that the FU811 tube life will be greatly extended. If there is a sudden power failure during treatment, the medical staff must return the "Output Selection" knob to the treatment "1" position in a timely manner, to prevent the output from being too large when the start button is pressed again. The treatment is divided into thermal effect and non-thermal effect of two ways, do not simply pursue the "thermal effect", especially to avoid the occurrence of excessive output current generated by the fat overheating phenomenon. The patient has a temperature perception disorder, the treatment should be very careful to avoid the output dose is too large. When treating the head, the patient should lie down or sit vertically, and the dose should not be too large. The treatment of what kind of disease, the application of what kind of electrodes, in what parts, the choice of how long the treatment time and course of treatment, should be carried out under the guidance of experienced physiotherapists.Other precautions
This machine should be placed in a separate treatment room, if not, it should be as far away as possible from other therapeutic instruments. Please be sure to connect the power cord of the machine to a three-pronged power outlet with a ground wire. The output cables of the machine should be as parallel as possible without crossing or circling. The outer cover of the electrode plate should be cleaned regularly during use, and the padding between the electrode plate and the patient during treatment should be sterilized by ultraviolet light or other methods to prevent cross infection. To ensure safety and prevent electric shock, do not open the rear cover after the machine is energized (except for maintenance personnel).
