Specification for disinfection and sterilization of dental instruments
Due to the particularity of dental diagnosis and treatment operations, dental medical institutions can easily become the hardest-hit areas for cross-infection. So how do dental hospitals disinfect equipment and protect the safety of doctors and patients. Next, let's take everyone to understand the process of disinfection of dental instruments.
In order to improve the cleaning quality of dental instruments, the pretreatment of instruments in the clinic is particularly important. After the treatment is completed, the nurse or medical assistant should promptly wipe the blood stains, stains, adhesives, dental filling materials and other residues on the surface of the dental instruments with dressings or alcohol cotton balls on the side of the chair. Store the instrument in a moisturized manner or send it to the disinfection room as soon as possible to prevent the dirt from drying out and affecting the quality of cleaning and disinfection.
When recycling the equipment, it needs to be closed for recycling and moisturizing, especially the working end, which can be placed in the recycling and washing rack containing the multi-enzyme solution, and placed in the recycling box for temporary storage; it can also be moisturized by spray-type enzyme moisturizer . The recycling container should be cleaned, disinfected and dried after each use. When recycling, pay attention to personal protection, check that the gloves are not damaged, and take standard precautions. It is forbidden to directly touch the sharp tip with your hands to avoid needle stick injuries. Small devices such as burs and mobile phones and other devices should be handled separately.
Manual Cleaning Operation Steps
1. Flushing: Rinse the instrument under running water to remove contaminants initially.
2. Brushing and scrubbing: The instruments after washing should be soaked with enzyme cleaning solution, and the liquid surface should be overwhelmed by the instruments during soaking to keep them fully moist. Brush and scrub again.
3. Final rinse: After scrubbing and scrubbing, rinse with purified water.
Ultrasonic Cleaning
1. Ultrasonic cleaning machine can improve the effect and efficiency of cleaning.
It is suitable for difficult-to-clean instruments such as blood-stained dental forceps, burs and other instruments with complex structures. Using ultrasonic cavitation, acceleration and direct flow in the liquid to directly or indirectly affect the liquid and dirt, so that the dirt layer is decomposed, emulsified and stripped to achieve a cleaning effect, which can penetrate into the blind that cannot be touched by humans. End and fine parts.
The ultrasonic cleaning time should be 3min-10min, and the cleaning time can be appropriately determined according to the contamination of the equipment and the power of the ultrasonic machine.
Note: Ultrasonic cleaning is only an auxiliary cleaning of manual cleaning.
Ultrasonic cleaners cannot vibrate to clean mobile phones, and can easily damage the bearings, especially expensive mobile phones (such as planted mobile phones). Then we can use our medical washing machine.
Mobile phone equipment is recommended to be cleaned by a medical washing machine
Dental handpieces are manufactured with precision and complex structure. They are in close contact with patients' saliva and blood during diagnosis and treatment, so special equipment is used for cleaning. Cleaning process: Rinse under running water to remove obvious dirt on the surface of the dental handpiece. Put the dental handpiece into the mechanical cleaning equipment, fix the dental handpiece, select the correct cleaning program, and start the equipment to start cleaning. The cleaning water flow and airflow conform to the internal structure of the dental handpiece.
Advantage:
1. Fully enclosed, non-contact, safe, hygienic, convenient, effective and fast;
2. The dental handpiece can be cleaned both inside and outside, and the cleaning effect is stable and reliable;
3. Integrate cleaning and disinfection
4. Different procedures can be selected, targeted, use reasonable time, appropriate temperature, quantitative cleaning agent, and effective cleaning of equipment to achieve the ideal cleaning and disinfection effect;
Device Drying
Dental instruments need to be dried before autoclaving. Place the instrument in a drying oven to dry. The appropriate drying temperature can be selected according to the material of the device.
Advantage:
1. Reduce the risk of wet packs, and more guarantee the pass rate of equipment sterilization.
2. It is beneficial to oiling and maintaining the joints of the equipment and the lumen of the mobile phone.
3. Reduce the risk of rusting of the equipment and prolong the service life of the equipment.
