Ultrasonic washing and thermal disinfection

Instrument cleaning

If we are to ensure that the entire sterilization process is completely effective and absolutely safe, each single phase must be performed with the utmost care. In particular, reusable surgical and microsurgical instruments must be perfectly clean before they are ready to be pouched and actually sterilized.

To achieve this, we need to use the most modern and efficient techniques available on the market and must avail ourselves of equipment that improves and automates the process as much as possible.

Used as part of the sterilization system, ultrasonic washing and thermal disinfection deliver safer results, a speedier process and tighter organization as well as reducing any risk of contamination and accidents.

How does ultrasonic washing work?

This is a washing process which involves the use of ultrasonic tanks and is an extremely important solution for cleaning those instrument parts which are difficult to reach. It dislodges any especially stubborn debris such as cements and plaster. The ultrasound cavitation process enables thorough in-depth cleaning of clinical instruments both inside and out.

Thermal disinfection of surgical instruments

Within the sterilization system, the purpose of the thermal-disinfection phase is to extirpate all viruses (including HBV and HIV) and bacteria. The bactericidal, virus-extirpation and fungicidal action is obtained by using detergents at set temperatures.

The thermodisinfector allows for heat disinfection of the instruments, thus doing away with the need for manual washing and drying. With this device, everything is achieved in a single cycle: pre-washing, washing, thermal disinfection, rinsing and drying. Not only this but the entire process is automated and delivers outstanding results, greater rapidity and fewer risks for the operator.

Moreover, this kind of equipment must comply with the requirements envisaged under sections 2 and 6 of regulation EN15883 which lay down that the minimum result to be achieved by the end of the full cycle must be A0=600, but that the thermodisinfector must be able to reach an A0 value which is not less than 3000 (A0 being the physical parameter which measures the ability of a thermal disinfection cycle to inactivate bacteria and other micro-organisms).

Once all phases of the automatic program have come to an end, both the external and internal surfaces will be clean and disinfected and the instruments will be ready for packing.

It should be pointed out that all instrumentation, including contra-angles and dental handpieces, which cannot be placed inside an ultrasonic tank may be thermally disinfected.

Cleaning as a phase in an integrated protocol

Ultrasonic washing and thermal disinfection are therefore an essential part of instrument cleaning and sanitation in any modern dental clinic. A vital part of the sterilization process of dental instruments.

See Eurosonic & Eurosafe ranges.

Euronda’s Pro System aims to offer an equipment range that is able to deliver outstanding cleaning results for all parts of the sterilization process as well and to provide a system which harmonizes all the various phases and machines which inevitably strive towards a common purpose: making sure that operators and patients can enjoy the total safety of completely sterile instruments which have been checked every step of the way.
