In dentistry, compressed air is used to use equipment such as syringes and handpieces. Compressed air is blown into the mouth through this device. Compared to the size of pores in the human body, which are approximately 0.02 to 0.05 mm, the size of foreign matter contained in compressed air is very fine, approximately 0.0001 mm to 0.01 mm. have a size. The size of the foreign matter contained in the compressed air is much smaller than the size of the pores. As such, it is very fragile and susceptible to infection. If dirty compressed air is strongly sprayed on the gums, it can cause secondary infection as well as cerebral infarction in the long term.
3-Way Syring (dental tools)
Water, compressed air, water/air mixture can be sprayed in three ways Spray directly into the patient's mouth Contains high concentrations of heavy metals, bacteria, viruses, and fine dust -High-pressure spray on gums, skin, and pores (harmful substances can penetrate)Malfunction of medical tools due to poor compressed air quality
3-Way Syringe, handpiece, etc. due to moisture in compressed air Prevention of aging, deformation and corrosion of consumable partsDuring treatment, saliva, blood, and contaminated foreign substances sucked through the suction are collected in a machine room located in a corner and discharged through the sewage pipe. Contaminated air sucked in together remains in the machine room as it is. The compressor re-inhales and compresses the contaminated air, It is sent into the mouth, and eventually repeatedly compressed, sprayed, compressed, sprayed with contaminated air. So, of course, secondary contamination of patients can occur, and it can cause fatal risks to doctors and nurses who stay in the clinic for a long time. The American Dental Association recommends a compressed air moving distance of 10m or more, and has established management regulations for particles, moisture, and oil.
Therefore, a compressed air filter must be used in dentistry as well. However, a general element filter generates differential pressure as it is used, Due to the discharge pressure much lower than the compressor input value, the failure of equipment such as handpieces is frequent.
