(I) General rules
1. The physiotherapy department should establish a safety system for various physiotherapy techniques, which all staff and patients entering the physiotherapy room should follow and check the implementation status regularly.
2. All newly purchased or faulty physiotherapy machines must be carefully inspected and tested to ensure that they are working properly and record cards are made before they can be used.
3. Before giving physiotherapy to patients, the condition should be carefully examined, the correct diagnosis should be made, the indications should be carefully selected, contraindications should be excluded, and the physiotherapy factors, methods and doses should be reasonably selected.
4. During each treatment, the technical operator must pay attention to the working status of the machine and ask the patient's response at any time, and deal with problems in a timely manner.
5. During the repair work, attention should be paid to the safety of personnel and machines. Comrades without repair work experience should not dismantle the machine at will, nor should they repair it alone to prevent accidents.
(II) Safety protection of grounding
1. Physiotherapy staff should have general knowledge of safe use of electricity and common sense of first aid for electric shock.
2. The floor of the electrotherapy room and phototherapy room must be wooden or covered with rubber. The treatment bed must also be made of wood. The heating pipes and water pipes around the treatment bed should be shielded by wooden fences.
3. Each treatment room must be equipped with a main power switch and fuse, indicator light, switch, socket, power cord should be well insulated, and the power socket should be grounded.
4. All physiotherapy machines with grounding wires should be well grounded.
5. Patients are strictly prohibited from contacting surrounding conductive objects or others during physiotherapy; patients are prohibited from touching the machine during treatment; conductive objects that touch the body, such as watches, belts, etc., should be removed.
6. When performing physiotherapy outside the physiotherapy room (in the ward, etc.), the patient's bed is metal (or metal table), and the metal part must be covered with rubber cloth or blankets to make the patient basically insulated before treatment.
(III) Protection against contact with high voltage electricity
1. Those without more skilled maintenance technology should not repair or touch the various components inside the machine when the power is on.
2. When using a high-frequency or ultra-high-frequency electrotherapy machine, the back cover of the machine should generally not be removed. When the back cover must be removed for heat dissipation in summer, a shielding net should be installed to avoid contact with high voltage electricity.
3. The high-voltage output wire should be well insulated. If there are cracks or damage, it should be replaced in time, and should be checked frequently and carefully. The wires cannot cross and touch each other. Check whether the plate electrode joints are good or not.
4. When repairing a treatment machine with high voltage electricity (high-frequency electrotherapy machine, laser electric excitation system, etc.), first check whether the machine casing is leaking electricity. When testing high voltage, first connect a ground wire, touch the measured point with a probe pen, and do not touch the casing with your hands; CO2 lasers and air ion generators should be discharged first and then tested after treatment; on the oscillating tube screen machine of the high-frequency electrotherapy machine, ordinary multimeters cannot be used to measure when high voltage electricity is on, so as not to damage the multimeter.
(IV) Prevention and treatment of electric burns
1. To prevent burns during direct current electrotherapy, the motor pad should be 1-2 cm larger than the metal electrode periphery and the thickness should not be less than 1 cm; the electrode pad must be in close contact with the skin and fixed securely; when the current density is above 0.1mA/cm2, close attention should be paid to the skin's reaction; low and medium frequency electrotherapy and pads should also have appropriate thickness and be in close contact with the skin and fixed; the contact part between the wire and the electrode should avoid touching the skin and can be protected with tape. If electric burns occur during treatment, they should be treated in time. ① Apply gentian violet locally; ② Expose to small and medium doses of ultraviolet light.
2. During high-frequency electrotherapy (long-wave electrotherapy), the wire must not directly contact the human body; during short-wave and ultrashort-wave treatment, the affected part must not be too wet, and if there is sweat, it should be wiped dry before treatment.
3. During various low- and medium-frequency electrotherapy, if the patient's skin feels tingling or burning, the power should be turned off for inspection.
(V) Harmful effects and protection of ultra-high frequency and ultra-high frequency electromagnetic fields
1. Short-wave and ultra-short-wave treatment machines with an output power of more than 200 watts should be used in a shielded room; if there is no shielded room, the working point where the staff stays the longest should be no less than 3 meters away from the generator; when there are more than four low-power ultra-short-wave treatment machines, a special treatment room should be set up, and the area should not be less than 24 square meters.
2. When using a high-frequency electrotherapy machine, the output tuning knob should be adjusted to the resonance point as much as possible; the distance between the two electrodes and the skin should not exceed 6 cm; it is forbidden to use the monopole method in a treatment room without a shielded room.
3. When using a microwave radiator to irradiate the affected part at a distance, it should be carried out in a special treatment room, and each treatment machine and bed should occupy 9 square meters of the treatment room area; when using microwaves in a general treatment room, a screen with microwave shielding performance should be set up, and the radiator should face the outer wall during treatment; when using the direct irradiation method without distance, it can be carried out in a treatment room without shielding equipment; staff should not stay in the direct microwave irradiation area. Wear goggles when irradiating the head.
4. Staff working in high-frequency electricity and microwave treatment rooms should undergo a physical examination every six months or one year. The treatment rooms should be rotated regularly.
(VI) Harmful effects and protection of light radiation and super radiation
1. It is forbidden to look directly at laser and ultraviolet light sources.
2. Personnel and patients undergoing laser and ultraviolet treatment should wear goggles.
3. When the laser is working, no one can pass in front of the light source to prevent laser injury (especially attention should be paid to CO2 laser).
4. When the ignited ultraviolet lamp is not used for treatment, the reflector cover should be opened to the floor. The treatment room should have ventilation equipment and regular ventilation.
5. When infrared rays are irradiated on the face or nearby affected areas, the eyes should be covered.
6. During ultrasonic treatment, staff should wear double gloves. When treating the head, eyes, heart and spinal cord, pulsed and small doses should be used.
(VII) Maintenance and repair rules for physiotherapy machines
1. The use of physiotherapy machines must be performed by specially trained physiotherapy professionals, and the operating routines of various physiotherapy machines must be strictly followed.
2. Before work every morning, the staff should clean the machine surface. If any obstacles occur during the treatment, stop using it and wait for maintenance before using it. Cover the machine when leaving get off work.
3. Avoid moving the machine after starting it, especially during ultraviolet and high-frequency electrotherapy. And prevent moisture.
4. Avoid using the high-frequency therapy machine for 2-3 hours continuously as much as possible. Use a fan to cool it if necessary in summer.
5. Non-undergraduate personnel are not allowed to touch or use the machine.
6. When using microwaves, the antenna cable connector should be tightened and checked frequently.
7. The maintenance of the physiotherapy machine should be carried out by professional physiotherapy technicians.
8. All kinds of physiotherapy machines should be regularly inspected and recorded during use. The inside of the machine should be thoroughly cleaned once every three to six months, and the dosage should be identified regularly.
