A pilot model of a plasma sterilizer based on dielectric barrier discharge (DBD) for disinfection and low-temperature sterilization of products for various purposes has been developed. It provides sterilization of reusable surgical instruments, rigid endoscopic, laparoscopic, endo-video surgical, microsurgical and other instruments, components of devices made from corrosion-resistant metals and alloys (stainless steel, titanium, etc.), as well as examination and surgical (otolaryngological, dental, gynaecological etc.) instruments, plastic sundries (fluoroplastic, polyvinyl chloride, polyurethane, polyethylene etc.), ozone-resistant medical rubbers (silicone, etc.), polymers, epoxy resins and glass. The sterilizer can be used in medical, sanatorium, outpatient and other medical institutions, as well as in military field surgery. Sterilization is carried out with ozone produced from oxygen by a built-in ozone generator operating on a dielectric barrier discharge with a high-voltage switching power supply providing up to 80 W. A high concentration of ozone in water (up to 16 mg/L) is achieved for effective and complete sterilization of medical tools at low temperature.
