Midbrook Medical, the Jackson, Michigan, based manufacturer of custom fabricated medical equipment and medical decontamination systems has announced that recent laboratory tests demonstrate the Tempest Surgical Device Washer produced a 6 log reduction in bacteria. The Tempest achieved this reduction using a combination of enzymatic detergent wash, ultrasonics, concentrated flush of the interior lumen of cannulated devices and high temperature disinfecting flush of all surfaces.

Midbrook Medical, the Jackson, Michigan, based manufacturer of custom fabricated medical equipment and medical decontamination systems has announced that recent laboratory tests demonstrate the Tempest Surgical Device Washer produced a 6 log reduction in bacteria. The Tempest achieved this reduction using a combination of enzymatic detergent wash, ultrasonics, concentrated flush of the interior lumen of cannulated devices and high temperature disinfecting flush of all surfaces.

The Tempest Surgical Device Washer was developed by Midbrook Medical as a solution for effectively cleaning the difficult to reach interior lumen of cannulated devices. Traditional washing methods using manual brushes struggle to consistently clean these areas, which results in bioburden remaining inside the instruments. This left over bioburden can drastically raise the possibility of patients or staff contracting healthcare acquired infections.

To deal with this high risk situation, Midbrook Medical introduced the Tempest Surgical Device Washer. The Tempest uses enzymatic detergent washing and ultrasonics to clean a wide range of medical instruments, and also utilizes a concentrated flush specially designed to clean the interior lumen of cannulated instruments. When the instruments are loaded, they are connected to specially designed ports in the baskets inside the system. During the flushing portion of the wash process, a concentrated flush is directed through these ports, thoroughly cleaning the interior of the devices multiple times within each cycle.

Recently, the Tempest washer underwent laboratory testing through Nelson Labs. The results of this testing showed that the Tempest produced a 6 log reduction in bacteria. This means that the amount of bacteria on the test device was 1,000,000 times lower following washing in the Tempest. This amount of reduction in only one cycle is significant. Heavily contaminated devices utilizing a blood / soil mixture (Miles Test Soil) were used to challenge the Tempest washing system with all devices testing negative for the presence of hemoglobin post-processing and protein levels far below the requirements indicated for cleaning in AAMI TIR30:2003. This high level of cleaning of all surfaces ensures that the devices have been cleaned to a point where it is then possible to sterilize them. With traditional washing methods, the bioburden remaining in the interior lumen makes it impossible to assure they can be consistently be sterilized. Including the Tempest as a step in the washing process effectively eliminates the risk of exposing unclean surfaces to a terminal sterilization process. The 6 log reduction in bacteria produced by the Tempest Surgical Device Washer is an important step forward in cleaning technology for cannulated medical instruments. Being able to adequately clean these problem instruments creates a safer environment for the doctors and patients that are in contact with them on a daily basis, and can help fight the growing problem of healthcare acquired infections in medical facilities.
