The main water supply pipeline discharges the old water
As the dental chair has been out of service for a long time, the tap water pipe in the consulting room and the water pipe in the dental chair are all old water. At this time, the flushing water supply function should be used to drain the old water and introduce live water. The drainage time shall not be less than 3 minutes, and observe whether the drainage of the spittoon jar is normal. At the same time, 50 ℃ warm water can be used to wash the drainage pipeline to soften the pollution of the pipeline.
Mobile phone pipeline flushing
Pick up the mobile phone tube to the upper part of the spittoon jar, open the water source, step on the foot to make the high-speed water flow wash the mobile phone tube, adjust the water regulating valve and air regulating valve of the mobile phone tube, and check whether the regulating valve can control the water and air volume of the mobile phone tube.
Disinfection of mobile phone water supply pipeline
Inject 0.5% hydrogen peroxide or low concentration hypochlorite disinfectant into the disinfection water bottle (independent water supply bottle), turn the water source switch to the disinfection water bottle, rinse the water pipe, keep the disinfection water in the pipe for 30 minutes, and then rinse it with pure water. (It is recommended to disinfect once a week)
The air compressor room shall be ventilated
Air compressor drainage and exhaust
Water accumulation in the air compressor will lead to non drying of gas and reduction of gas capacity. Drain the air compressor, discharge the air after the water is drained, then start the air compressor, and observe whether the air compressor automatically stops after reaching the rated air pressure.
Check whether the air pressure value of the barometer is normal (the normal air pressure value is 0.5-0.8Mpa, low air pressure value will lead to low speed of the mobile phone, and high air pressure value will affect the service life of the pipe).
Strong and weak suction pipe
1. Flushing of strong and weak suction pipes
2. Turn on the water flushing function of the spittoon, pick up the strong suction pipe and the weak suction pipe to directly suck the water in the spittoon tank, suck it for 3 seconds, then suck it for 3 seconds, and then move it away, and so on for 5-10 times. (After each treatment, the strong and weak suction should be washed with water)
3. Cleaning of strong and weak suction filter screen
Take out the filter screen, clean it with a small brush and then install it back. (The blockage of the filter screen will lead to insufficient suction, which will affect the doctor's operation and cause discomfort to the patient's treatment experience. It is recommended to clean it once a week.)
Self check list of working status
1. Negative pressure system: because various drugs will be used for oral treatment, the patient's saliva will cause corrosion damage to the rotor of the negative pressure pump, and the residues in the pipe will have a peculiar smell, so each patient needs to draw about 10 seconds of clean water to clean the pipe after treatment, and the delayed closing function of negative pressure is specially designed for this purpose.
2. Clean the pipeline by pumping clean water for about 30 seconds after treatment every day.
3. During the long holiday, let the negative pressure pump run for 10 minutes every three days.
4. Inspection for working condition of dental chair
5. Check whether the working state and speed regulation of high and low speed mobile phones are normal.
6. Whether the working water of mobile phone is normal.
7. Whether the air filling of the water storage bottle is normal, and whether the change-over switch between the tap water and the water storage bottle is normal.
8. Whether the oral lamp works, and whether the color temperature and brightness are adjusted normally.
9. The lamp arm height is self stable.
10. Whether the heating function of the water heater is normal.
11. Whether the spittoon flushing and water supply time can be set.
