Instruments Reprocessing

Each medical device must be reprocessed with a suitable method after each use, according to its classification and risk assessment. Manufacturer information and measures for occupational safety (gloves, goggles / face protection, splash guard, protective clothing) must be strictly observed during the entire instrument preparation.

Preparation for disinfection

Instruments should be disinfected and cleaned as soon as possible after use, thus avoiding the drying of impurities. Remove gross contamination with a disinfectant cloth. Store dry, closed, non-sterile container for a maximum of 6 hours.

Disinfecting cleaning / rinsing / drying

The solutions used for instrument disinfection and cleaning (combined disinfectants and cleaning agents are to be followed according to the manufacturer's instructions regarding contact time and concentration.) VAH-listed, non-protein-free. Rinse instruments thoroughly with water and dry carefully. Cleaning materials must be cleaned and desalinated at least once during a work day.

Important: After removing the instruments from the wet disinfection solution, they must be carefully dried. If you can, you should use compressed air to blow dry the instruments. For example, there would be no residual moisture behind the springs and in the joints of the pliers.

Check for cleanliness and integrity

Visual check for cleanliness, integrity and functionality of the instruments, if necessary by means of an illuminated magnifying glass (3 - 6 Dptr.). Removal of detected contaminants.

Final disinfection or sterilization

The risk assessment and classification of medical devices determines the treatment.

Ultrasonic cleaning

For cleaning in an ultrasonic bath, instruments must be kept open. In order to achieve a good cleaning result, a temperature of at least 50° to 70° Celsius should be given in the ultrasonic bath. Basically, ultrasonically cleaned instruments must then be subjected to an intensive rinse with clear, desalted water, better yet with distilled water. After rinsing, carefully dry the instruments!

Hot air sterilization

Observe manufacturer's instructions. If you avoid them, it can be detrimental for the instruments. For instance, you exceed the target temperature of 180°. Depending on the load, the treatment lasts 60 min. If the temperature is exceeded, the steel may be softened.

Autoclave Steam Sterilization

When using steam sterilization, care should be taken that the sterilization steam is free of contaminants. The steam for sterilization purposes must comply with DIN 58 946. Steam quality contaminants such as oil, chemicals, metal chips or rust can cause consequential damage to the instruments. The recommended temperature should be followed exactly as specified by the manufacturer. As a rule, it should be at 134° Celsius. Treatment time: 5 minutes. Packaged sterilization in an autoclave at 134° C for 5 minutes corresponds to: Sterile treatment.

Care, Repair and Functional Test

Maintenance is to be understood as meaning the application of lubricants. We recommend maintenance oil (oil containing silicone) on all joints and moving parts. The oil is water repellent in addition to its lubricating properties, if there are still traces of moisture. Subject all instruments to a functional test, remove any damaged ones immediately and, if necessary, arrange for repair.

Documentation of the Treatment

The completion of the treatment must be comprehensibly, documentation of the entire reprocessing process by means of a hygiene manual or a hygiene plan.


Store instruments in a dry place protected from dust, preferably in closed storage or storage systems. Regular storage checks (First In - First Out) Clean / Disinfected storage location.

Notes on Medical Device Preparation

The legal basis for the reprocessing of medical devices is the Medical Devices Act and the Medical Device Operator Ordinance. The operator is obligated to control all steps of the treatment, to determine the treatment procedures and conditions, to check their successful execution and to document in writing the entire procedure in the hygiene plan. The manufacturer ensures that the listed procedure is suitable for reprocessing Alfred Hermann instruments. The operator is responsible for the actual reprocessing of equipment, materials and personnel. In addition, validations and routine monitoring of the process are required.

This manufacturer information applies to all instruments supplied by Alfred Hermann.
