Areas of application This washer-disinfector can be fitted with a variety of mobile units, which can be equipped with a variety of modules and inserts depending on the type and shape of items requiring cleaning and disinfection. Select mobile units, modules and inserts which are appropriate for the application. Notes on the individual areas of application and examples of loading are given on the following pages.
Areas of application Loading the machine – Arrange the load so that water can access all surfaces. This ensures that it gets properly cleaned. – Do not place items to be cleaned inside other pieces where they may be concealed. – Hollow instruments must be thoroughly cleaned, internally and externally. – Please check that instruments with long narrow hollow sections can be flushed through properly before placing them in inserts or connecting them to jets.
Areas of application Surgical instruments (OP) Surgical instruments should be stored for as short a time as possible before machine processing. The OXIVARIO programme is recommended for instruments where there is a long delay between the time they are used and the time they can be reprocessed. See "Special features" at the end of this booklet. Disinfection of surgical instruments, and of those used for minimal invasive surgery should preferably take place thermally.
Areas of application Anaesthetic instruments (AN) Anaesthetic instruments should be thermally disinfected using the DES-VAR-TD-AN programme. If this is not possible, they can be processed using a chemo-thermal programme. The water level in the machine should be increased when using a chemical disinfection programme. To establish the effectiveness of chemo-thermal disinfection, consult the manufacturer of the disinfecting agent being used.
Areas of application Baby bottles (BC) For example, 95 baby bottles can be accommodated in 5 x E 135 containers and 72 wide-necked teats in an E 364 or 72 screw connection teats in an E 458 in one batch. – Ensure the level marker on the bottles is machine-washable. – After use, if there is a delay (e.g. 4 hours or more) before washing the bottles, fill them with water to prevent residues drying on before the bottles are washed.
Areas of application Operating theatre shoes (OS) Polyurethane operating theatre shoes, and/or insoles should be cleaned and chemo-thermally disinfected at 60 °C. These can only be thermally disinfected (using programme SHOE-TD-75/2) if the manufacturer states that they are made of a suitably heat-resistant material. To establish the effectiveness of chemical disinfecting agents for chemo-thermal disinfection consult the manufacturer.
Areas of application Laboratory glassware (LG) Wide-necked laboratory glassware, e. g. beakers, wide-necked Erlenmeyer flasks and Petri dishes, and cylindrical shaped items e. g. test tubes, can be cleaned and rinsed, internally and externally, by the action of the rotating spray arms. They can be arranged in full, half and quarter inserts in an empty bottom or top basket with spray arms.
Areas of application Transfer trolley for loading and unloading the machine ,When a disinfection process is being carried out according to nationally laid down hygiene standards (e.g. § 18 IfSG), the contaminated surfaces of the trolley must be disinfected, after the machine has been loaded, using a spray disinfectant in accordance with national health and safety regulations and § 18 IfSG.
