Washer/Decontamination Units, Surgical Instrument
Definition : Washer/decontamination units designed for automatic or semiautomatic washing (i.e., eliminating dirt and/or stains) and physical removal (i.e., physical decontamination) of organic debris such as blood, fat, bone from surgical instruments, reusable respiratory devices (e.g., anesthesia sets), and other critical devices. These units typically consist of a corrosion-resistant chamber containing baskets or trays for the soiled instruments; some can accommodate instrument trays and/or dedicated racks. The equipment performs a cycle of operations typically including water prewash, enzyme treatment, detergent wash, heated rinse, and drying; the process includes mechanical removal of contaminants by water jets and/or ultrasound energy and may include thermal disinfection (usually using water from 60 to 95 degrees Celcius [140 to 20 degrees Fahrenheit]). Surgical instrument washer/decontamination units are frequently used as an adjunct to manual cleaning of surgical instruments before sterilization; they provide some level of disinfection by killing or inactivating several types of microorganisms. They are available in stand-alone and wall-recessed configurations, typically for use in central supplies departments of healthcare facilities.
