Cleaning

Cleaning the surgical instruments

The cleaning process for surgical instruments is the first step in the sterilization process and aims to remove dirt from the instruments. The removal of such impurities prior to sterilization is mandatory, as residual dirt can render the sterilization process ineffective. Following the inactivation of viruses and bacteria by decontamination, the instruments must be manually or mechanically washed. This step should be carried out wearing PPE. Mechanical washing involves the use of ultrasonic equipment or thermodisinfectors that allow the physical and chemical breakdown of bacterial contaminates.

Ultrasonic washing

It is carried out through the use of ultrasonic tanks and is essential for cleaning the instrument in parts that cannot be reached or for removing particularly stubborn dirt such as cement.

Compared to manual washing, ultrasonic washing has several advantages, including:

• The automated cleaning process is more effective;
• Reduced risk of accidental injuries;
• Low risk of environmental contamination;
• Reduced staff time.

Useful tips for effective ultrasonic cleaning of surgical instruments

• Check the effectiveness of the ultrasounds periodically;
• Use suitable and authorised disinfectants;
• Adhere to the correct water concentration and temperature;
• Do not place instruments on the bottom of the tank and always use baskets or beakers;
• Do not immerse mouth mirrors with other instruments, they may get ruined;
• Do not immerse motors and mechanical components;
• Do not immerse diamond burs;
• Do not immerse fibre-optic instruments and elastic bands.

Eurosonic Ultrasonic Tanks

Eurosonic is Euronda Pro System’s Made in Italy range of ultrasonic tanks. Eurosonic devices fulfil the requirements of medical and dental surgeries by offering a differentiated range in terms of capacity, preset washing programs and working temperature. Compact and ergonomic, they guarantee efficiency and extreme practicality in daily use, thanks also to an immediate and intuitive control system.

Thermodisinfection

This is the thermal disinfection phase at 93°C that occurs at the end of the automatic washing cycle of the instruments. Thermodisinfection includes washing, rinsing, disinfecting and drying of the surgical instruments, which by the end of the treatment process will be perfectly dry and disinfected, and ready for an effective sterilization cycle.

The thermodisinfection process takes place thanks to the combined action of detergents, temperature and time, and has several advantages such as:

• Reduced environmental contamination;
• Ideal for rotary instruments (turbines and micromotors);
• Monitored and verifiable washing parameters;
• Process traceability;
• Reduced staff time.

Useful tips for proper thermodisinfection of surgical instruments

• Do not place instruments on top of each other so that the water can act on all surfaces;
• Do not insert objects that may block the movement of the washing arms;
• Place pointed and sharp instruments in the appropriate basket, with the tips pointing downwards;
• Check that the material to be washed is compatible with thermodisinfection at 93°C;
• As recommended, use detergents approved by the manufacturer of the thermodisinfector in order to maintain washing performance.

Eurosafe thermodisinfectors

Eurosafe is the Made in Italy thermodisinfector line from Euronda. Eurosafe 60 and Eurosafe 170 are the two Pro System devices that, thanks to a wide range of accessories, are able to meet the different requirements of medical and dental practices in terms of capacity and process speed.
