The Preparation of medical devices and medical instruments are subject to the Medical Devices Act and must be included in the reprocessing steps a risk of infection for Exclude patients, users and third parties. Only for reuse suitable and approved according to the regulations and directives Instruments, medical devices and utensils of all kinds, can be assigned to the reprocessing. The practice or clinic area, by using contaminated products, have exemplified the following impurities, body fluids, Taps, tissue samples, stool, serum, cell cultures, pharmacy substances and residues of others Art. These are prepared in standardized processing steps. In the relevant state of the art, this happens first manually, by dipping the polluted and contaminated to be cleaned workpieces in sinks, or in other transportable containers. Contemporary and at greater need the cleaning takes place in supportive automated machine technology, the cleaning technology is widely used in the functioning of dishwashers or dishwashers. These take over the Aufbreitungsschritte and the further processing of the introduced Workpieces, with different types of liquid Media. This is done with the process technology by pumping, Valves and components, pressurized, via rinse arms and nozzles. With liquid media, such as cleaning solutions, Disinfectants or acids the thorough processing takes place for operational safety for the hygienic clean reuse. Bacteria and fours become inactivated, with a broad spectrum of active ingredients, neutralized and dried.

Of the Transport of contaminated instruments and endoscopes takes place in different transport containers, with the aim to prevent bacterial carryover, as well to avoid rapid adhesion and drying of the residues and thus along with odor nuisance to minimize. Thus many containers are used, those with predisinfecting liquids filled are and take over the task, to slow down the drying phase. For the following work steps, a coarse dirt cleaning, by rinsing, or a manual brush cleaning with washing and cleaning, however, the transport containers are not designed. A constant manual repacking of the components, to the next processing step is necessary.

The Standard preparation steps do not differ, regardless the chosen one Cleaning steps or a possible subsequent machining. A thorough, optimal pre-cleaning, manual cleaning, with washing and brushing, according to the hygienic guidelines and requirements, compliance with regulations and recommendations, according to the hygiene plan are necessary and are the most optimal basis for the following Processing steps. Only with thoroughly pre-cleaned items can the disinfectants or acids, inactivating, with a broad spectrum against bacteria and viruses and for sure killing contribute to the contaminated instruments. The results of the hygienic Safety in the processing, are determined by inspections of the process or result quality of the treatment, constantly monitored by legal guidelines and tests in the interval.

suitable and approved instruments can be sterilized from 121 ° C, this takes place with heat, Pressure and vacuum.

In the automated reprocessing process by process engineering controlled devices, in the design of dishwashers with rinse arms, however, can also the following hygienic disadvantages in the automated program sequence occur. There are turbulences of dissolved Schmutzanhafttungen on other workpieces to be cleaned. Protective arrears become in vortex strands into zone areas, where a so-called rinse shadow occurs. This happens in areas of the cleaning chamber, at the rear walls, the storage areas, loading baskets, extracts and support points. Particularly resistant are, for example, adherence of proteins, Protein and Blood that favors by the temperatures of the media, concurrent with the connected one material heating the components to be cleaned, the attachment process of the swirled Favor particles. In The cleaning chamber may be affected by remaining contaminated residues on the surface Encapsulation to microbiological pressures and a population come, and thus these surfaces are not penetratingly safe, killed by pathogens. The efficiencies and quality improvements taken dishwashers, by a higher one Jet printing, additional rinse arms and perfecting the nozzles, the higher Pressure and radiation on the introduced workpieces caused stand in contrast to the fine instrument seals, splices, Optics and small inventory. The designed surface with Corrosion and wear protection or for an attractive look, are strongly attacked by the processes, surface structures of different materials removed, as in coatings, the object surfaces change. The roughness depth in the material structure increases and causes again here, in the surface structure, prefers the following dirt adhesion and deposition. microorganisms colonize the product surfaces and are often means of transport for the transmission of pathogens on the human. Despite elaborate cleaning and disinfection measures are usually the surface the items used or used, the cause of the transfer the pathogen involved. Counterproductive is the minimized renewed cleanability, the material destroying load and the concurrent influencing of the material structure properties.

The Preparation steps become more complex and additionally minimize the Life of the workpieces, through early Repairs and low longevity. For the users, like in a hospital in a central sterilization, it is therefore necessary at each Charge to perform a visual inspection, with manual, punctual Rework. This is practiced before the subsequent sterilization carried out becomes. The resulting cost increases.

Scientific Evidence also shows the carryover of animals to other areas via the dishwasher process. This is done by bringing together different ones Instruments and utensils of various kinds Departments, in a machine, with a cleaning chamber. Out the known findings were implemented, so today, no alround equipment for the Cleaning cycle more done, but for the respective functional area, the Reprocessing is made.

The Disadvantageous complexity remains, with ever-resistant and more immune, fours and bacteria, too when using more aggressive disinfectants, solutions and acids consist.
