Maintenance and repair of dental equipment

      Dental equipment is essential medical equipment for dentists. In recent years, the application of a large number of new technologies has made dental equipment more humane. Gas, water, and electricity are the three essential elements of dental equipment, so the gas and water pipelines must be laid out before installation (preferably from underground). It is best to install a first water filter in the waterway to avoid impact For the life of the water filter element in the machine, the air pump should not be too close to the treatment chair, so as not to affect the patient's treatment by the noise during pumping. If there are more equipment, it is recommended to use central gas supply, which can not only save expenses and reduce failures, but also ensure the quality of gas supply

      Usually, the newly purchased equipment is installed and debugged by the manufacturer, but it is best to have a doctor present during the installation process, so that the problems that arise in future work can be solved as much as possible by themselves.

      The comprehensive dental treatment chair has a conjoined type and a split type. The conjoined type is mostly composed of three parts: the patient's chair, the doctor's chair and the treatment machine. Among them, the patient seat has two kinds of electric and manual control. The electric power part has three types: screw drive type, electro-hydraulic type and belt drive type. The manual control mainly uses the foot pedal to control the seat position using oil pressure. The treatment machine is mainly composed of high-speed dental handpieces, low-speed dental handpieces (pneumatic or electric), three-purpose spray gun, saliva suction device, automatic water dispenser, instrument tray, shadowless lamp, X-ray film viewer, dental scaler, light curing machine ( Usually it is optional), sputum bowl and control parts of air, water and electricity. The principle of action is mostly to control water and electricity by air to treat oral diseases such as tooth extraction, tooth insertion, tooth repair and tooth cleaning.

        Because dental equipment is a necessary equipment for dentists to treat patients, the usage rate is high. It is also a device that integrates gas, 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.

        The first is the maintenance of the dental handpiece, which is a key component of dental equipment. During use, in order to avoid cross-infection between patients, the dental handpiece must be sterilized by high temperature and high pressure. In order to prolong the service life of the dental handpiece, special attention should be paid 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 dental handpiece 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.

       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. It is particularly worth mentioning that after the air is turned off, the air in the lumen must be exhausted with a three-purpose spray gun to avoid the pipeline. Long-term in a high-pressure state, easy to aging and cracking. Clean the water filter regularly according to the local water quality, and regularly drain the water in the air filter pressure relief 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.

       In the maintenance of the patient seat, the transmission components should be checked regularly, and the position of the mechanical transmission should be regularly lubricated. Electric hydraulic transmission should regularly check the oil quantity and oil quality in the oil tank, and timely add and replace when the oil quantity is insufficient or the oil quality is not good. The belt drive should pay attention to adjusting the tightness of the belt.
