Instrument cleaning

Safe reprocessing of used surgical instruments is only possible with thorough cleaning. With an ultrasonic cleaning device and the appropriate cleaning and disinfection preparation, contaminants such as blood and tissue residues can be safely cleaned from the instruments and the objects disinfected at the same time.

Applications of the ultrasonic cleaning units

The reprocessing of medical instruments with ultrasound enables a fast instrument cycle and gentle intensive cleaning by disinfection and cleaning in 5 minutes with STAMMOPUR DR 8. The usual damage and wear of the instruments by manual "brushing" is thus excluded. In the dental field, SONOREX ultrasonic baths are used in particular for instrument preparation and impression mould cleaning. Due to the insert cups specially developed for this application, impression mould cleaning and instrument disinfection with different cleaning preparations can be carried out simultaneously in one unit.

Which instruments can be reprocessed with ultrasound:

- General instruments such as scissors, needle holders, tweezers, forceps, trocars, scalpels
- Micro-instruments from neurosurgery and ophthalmology
- MIS instruments such as dismountable tubular shaft instruments, microclamps, etc.
- Endoscope accessories such as biopsy forceps, slings, valves
- ECG, EEG electrodes

Advantages of instrument reprocessing in an ultrasonic bath

- Fast instrument circulation
- Time reduction of the chemical disinfection to 5 minutes
- Protection of the instruments
- short contact of the instruments with disinfection and cleaning liquids
- No risk of corrosion
- Economical use of water, chemicals and energy
- High cleaning effect in hard-to-reach places, such as boreholes, joints or grooves, without mechanical damage

Which ultrasound scanner do I choose?

- Size of the cleaning objects determines the tub size and thus the type of appliance
- Dimensions of the hanging baskets must be observed
- To avoid overloading the unit, it is advisable to choose the next larger unit.
- this also gives scope for further applications

Is heating required?

Unit without heating:

- for simultaneous disinfection and cleaning after dry filing
- Disinfectant liquids must not be warmed up
- at temperatures above 40 °C there is a risk of protein coagulation

Unit with heating:

- For cleaning after wet filing or for basic cleaning
- Impurities are removed more quickly

What to consider when using the ultrasound scanner

- The items to be cleaned must not lie directly on the bottom of the tub.
- Do not stack instruments and do not overload baskets
- Open articulated instruments, e.g. forceps or scissors, completely and disassemble if necessary.
- Instruments must be completely covered with solution
- Air from cavities must escape Recommended liquids
- STAMMOPUR concentrates were specially developed for disinfection and cleaning in the ultrasonic bath
- The corresponding microbiological reports are available for the disinfection time reduction in the ultrasonic bath.
- Flammable liquids such as alcohols and aggressive cleaning liquids such as acids and salt solutions are not permitted for use - disinfection or cleaning is not possible with water alone - without suitable additives.

Disinfection and cleaning preparations

The optimum effect of ultrasound requires the use of special disinfection and cleaning preparations. These must have cavitation-promoting and material-protecting properties for use in the ultrasonic bath. Protection of the objects and the oscillating tank must be guaranteed even during intensive use. Many disinfection and cleaning preparations may contain components that attack the stainless steel oscillating tank. STAMMOPUR preparations have been specially developed for use in the ultrasonic cleaner. Medical products, CE-marking. All preparations are environmentally friendly, biodegradable and easy to dispose of.
