Maintenance of dental chair

Because the dental comprehensive treatment chair is a necessary equipment for dentists to treat patients, the utilization rate is high. It is also a device that integrates air, water, and electricity. Daily maintenance is directly related to the length of equipment life and the equipment integrity rate, so daily maintenance work is particularly important.

1: First is the maintenance of the hanpiece. It is a key component of the dental comprehensive treatment chair. During use, in order to avoid cross-infection between patients, the handpiece must be sterilized by high temperature and high pressure. In order to extend the service life of the handpiece, special Pay attention to daily maintenance.

Before the first use, use the injection needle to drop 1 to 2 drops of high-speed lubricant on the shaft. Under normal circumstances, the front of the car should be cleaned with a cleaning lubricant once a day, and the miniature bearings should be cleaned once after every 2 weeks of work. The normal working pressure of 0.2～0.25Mpa should be maintained; when there is no water, the mobile phone cannot be idling, otherwise the bearing will be damaged. When the bur is blunt, replace it with a new bur in time, otherwise it will affect the life of the bearing.

2: The maintenance of the treatment machine is mainly the maintenance of the air circuit and the water circuit. The air, water, and electricity should be turned off every day after get off work.

Clean the water filter regularly according to the local water quality, and regularly drain the water in the air filter pressure reducing valve: clean the powerful suction device and saliva suction device in time, take clean water frequently, and clean the pipeline. One thing to pay special attention to is that the water pressure and air pressure must be within the specified range to avoid bursting of filters and pipelines: operating lights and film viewing lights should not be switched on and off frequently, which will shorten the life of the bulb.

3: In the maintenance of the patient seat, each transmission component should be checked regularly, and the position of the mechanical transmission should be regularly lubricated.
