Safe and Secure Medical Equipment Supply Service
Osaka University Hospital's Central Sterile Supply Department was established on February 20, 1971 in order to provide efficient and reliable sterilization, centralizing the cleaning and sterilization of medical equipment, which had previously been done independently in each section and department, and the provision of sanitary materials. Then in September 1993 its name was changed from Central Sterile Supply Department to Sterile Supply at the time of relocation of the hospital to the Suita district. Cleaning and disinfection of flexible endoscopes, which had been done at the Endoscopy Center, was centralized in April 2008, and then initial washing by each department was abolished in April 2009. Sterile Supply provides quality assurance for reusable medical equipment in a centralized process, striving for safe and reliable medical equipment supply service.
Sterile Supply's staff consists of the director (professor), a deputy director (first-class sterilization technician, 1 supervisor (clinical engineer), 1 special technical staff (first class sterilization technician), 1 part-time medical technical staff (clinical laboratory technician), 1 part-time nursing technical aid.
Washing and sterilization of medical equipment is done by 50 outsourced employees.
The overall logistics of disposable (single use) medical equipment from ordering to inventory is handled by outsourced employees (SPD: Supply Processing and Distribution).
Various contaminants (blood, body fluids, minute tissues, etc.) and micro-organisms adhere to equipment used in medical wards, outpatient clinics and surgery. To remove these from the equipment, the chemical action of detergent is combined with physical effects of ultrasound, brushing and water jet for highly efficient washing.
Depending on the material of the equipment, mainly three kinds of sterilization are used: high-pressure steam sterilization (autoclave), ethylene oxide gas sterilization, and hydrogen peroxide low temperature gas plasma sterilization.
The staff endeavors to select the washing and sterilization method appropriate to the form and material of the medical equipment, and provide safe and secure medical equipment every day.
Washing and disinfection of gastrointestinal and bronchial endoscopes
In addition to the 8,000 gastrointestinal and bronchial endoscopes used in diagnosis, treatment and tests each year at the Endoscopy Center, this center has also begun cleaning and disinfecting flexible endoscopes used for outpatients of Otorhinolaryngology-Head and Neck Surgery and of Gynecology.
