Improper maintenance of dental chairs will not only bring a bad medical experience to patients, reduce the service impression of the hospital and clinic, but more seriously threaten the health of medical staff. Since the dental chair is a necessary equipment for dentists to treat patients, it has a high usage rate and is a device that integrates gas, water, and electricity. Daily care and maintenance are directly related to the length of equipment life and equipment integrity rate, so daily care and maintenance Work is particularly important.
Dental chair maintenance
1. Lubrication: The dental chair is still in the stage of mechanical and electrical integration, so the motor should be lubricated every six months or so. (You can use butter to smear the expansion joints)
2. Leather surface of the dental chair: Try to avoid scratches by the patient’s keys and other sharp objects.
3. Dental lamp: The lamp arm is controlled by a tension spring. When not working, try not to pull the lamp head back and forth.
Dental chair maintenance
Mainly maintenance of air and water circuits. You should turn off the gas, water, and electricity after get off work every day. It is particularly worth mentioning that after turning off the gas, you should use a three-purpose spray gun to release all the air in the pipe cavity to prevent the pipeline from being under high pressure for a long time and prone to aging and rupture. Another point to pay special attention to is the water pressure and air pressure, which must be within the specified range to avoid bursting the filter and pipeline: the dental light and film viewing light cannot be turned on and off frequently, which will shorten the life of the bulb.
Before daily treatment
Preflush the pipeline for five minutes to ensure that the water, gas, electricity, and negative pressure required for treatment are ready to provide guarantee for treatment.
Flush the mobile phone pipes to ensure that water and air are ejected smoothly from the mobile phone pipes.
Try pressing the automatic chair position and spittoon water discharge buttons to ensure that the dental chair lifts and the spittoon water discharge is normal.
Any area that the doctor's assistant can come into contact with when operating the dental chair needs to be wiped with an isolation film or disinfectant wipes to reduce contamination and possible corrosion.
Use a rag soaked in disinfectant to wipe the headrest, backrest, lumbar support, armrests, cushions, instrument tray panel, assistant position panel, operating light and saliva suction tube head of the dental chair accordingly.
daily cleaning
Special reminder: It is recommended to use clean water or soapy water to scrub the leather pad and surface of the dental chair. If you always use a cleaning solution containing chemical components to clean and wipe, you need to wipe it with clean water again to prevent chemical components from remaining on the surface of the leather pad or metal parts and causing corrosion. It is best to wipe it with warm water before use in winter and then put it into work.
Decontamination: Use detergent and wipe with a soft cloth or brush. Rinse with clean water and dry other difficult-to-treat stains. Use lighter oil (naphtha) to carefully wipe the stained area, use a soft cloth to gently wipe the surface, then rinse with clean water and dry.
Daily disinfection
Disinfectants such as phthalaldehyde/quaternary ammonium/glutaraldehyde/hypochlorous acid can be used
The following disinfectants will damage the surface of the equipment and are not recommended for use:
Strong phenolic/phenolic alcohol blend
Sodium Hypochlorite/Household Bleach Sodium Bromide
high concentration of alcohol
Household cleaner (for dental equipment only)
citric acid
Sodium chloride
Hydrogen (0.5%)
In addition, ultraviolet disinfection or long-term sunlight exposure can also cause damage to the cortex of the dental chair.
After treatment for each patient
Clean and disinfect in time to prevent the virus from being transmitted to patients and medical staff through air, water, contact and other channels.
After daily treatment
Thoroughly clean and disinfect all pipelines and ducts to prevent the growth and spread of germs, ensure a safe working environment, and avoid cross-infection.
Rinse the spittoon for 3-5 minutes, take out the spittoon filter and scrub it under running water. Soak it in disinfectant and put it back.
The strong and weak suction tube absorbs a large amount of clean water or negative pressure cleaning fluid, cleans all negative pressure pipelines, and cleans the filter.
Regular cleaning
The pure water in the water storage bottle needs to be replaced every day. The water storage bottle should be cleaned, disinfected, and dried every day before being stored for later use to prevent the formation of biofilm.
(It is recommended to use a hypochlorous acid dental water supply disinfection machine to disinfect the water source of the clinic, inhibit the formation of biofilm in the dental chair waterway, and is not harmful to the human body or equipment, saves time and effort, and reduces the workload of medical staff)
Special attention is needed in winter
1. Due to frequent use of the mouthwash heating function in winter, it must be turned off promptly at the end of diagnosis and treatment. It is necessary to cut off the power of the dental chair before leaving get off work to avoid continuous heating when the heating cup is not working and malfunction.
2. Let the suction machine idle for a period of time before leaving get off work to ensure that the water inside is completely drained and to prevent freezing at night when the temperature is too low.
