Cannulated Surgical Instrument Washer Preventing HAIs
Though it appears clean, surgical instruments could be harboring microbial contamination trapped in interior spaces that is difficult to remove. This is especially the case with cannulated instruments or instruments with moving parts. Manual washing isn't always enough and can still leave behind bacteria that can spread during surgery, which puts patients at risk of hospital-acquired infections. Now there is an alternative cleaning process through an automated multi-process washing approach where surgical instruments are cleaned completely, both inside and out. First, each cannulated instrument is attached to one of twenty-four specialized ports. Non-cannulated instruments can be placed freely in the trays in the open position. With the push of a button, the fully automated wash sequence begins. The wash tank is filled with 120-degree water that is dosed with enzymatic solution, loosening blood and other unintended debris from the instruments. During the 21-minute soak, the ports direct a flow of solution along the interior surface of the cannulated instruments, allowing the instruments to sit with enzymatic solution inside. After soaking, the ports are flushed with a fresh water and air mixture. The micro bubbles in the agitated flush implode due to ultrasonic action that dislodge any bioburden. Fresh water is then flushed through the cannulated instruments. The fresh water and air mixture occurs three separate times during the 21-minute process. At the conclusion of this sequence, the drains are opened and the wash tank empties. The interior of the cannulated instruments are rinsed with a 196 degree fresh water for four minutes followed by an exterior rinse with 196-degree fresh water for another 4 minutes. The final process is a two-minute cold water ozone spray which will remove contaminants without leaving behind chemical deposits on the outside of the instrument. After 32 minutes of these combined processes, the wash cycle is complete and the cleanliness of the instrument has surpassed AAMI standards.
