Infections caused by vascular prosthetics grafting is one of the most dangerous complication of vascular surgery, which often causes extended hospitalization, loss of organ or limb functions, or death1.
Preventing these infections significantly impacts mortality and hospital costs.
White et Al.2 documented that 70% of the germs found in the surgical wound are transported by the instruments, which, by transporting the micro-organisms inside the wound, deeply into the organism, promote germ settlement and infection development. A high bacterial count can be found on the surgical instruments used during surgery as early as 60 minutes after its start3. Colony-forming units (CFU) grow along with the exposure time, the number of people present in the operating room and the number of times the doors are opened.
TOUL focused laminar flow creates a sterile air flow directed toward the instruments table and/or operating field, removing 99.9% of airborne bacteria and micro-organisms, including Coronavirus.
With TOUL, you can transform an ISO 7 cleanroom into an ISO 5 cleanroom. According to strict Standard UNI 11425 2011, ISO Class 5 cleanrooms are mandatory for specialized surgeries, such as organ transplants, implants, neurosurgery and oncologic surgeries, and other complex surgeries lasting longer than 60 minutes. These procedures require an extremely high level of protection of the high-risk area (operating table, instrument table and surgeons operating space).
TOUL is compliant with the strict Standard ISO 5 and preserves the instruments and operating field sterilization even during very long surgeries, without any time restraints.
