Pistoning prevention system (PPS) of indwelling Foley catheters
View Patent ↗A pistoning prevention system (PPS) that will improve catheter associated urinary tract infection rates of an indwelling Foley catheter while maintaining reliability, comfort, & safety. With the PPS incorporated within a Foley catheter during manufacturing it will eliminate the excess stretch along a specific length of a Foley catheter that resides within the patient's urethra. The excessive amount and ease of stretch is responsible for the pistoning action of an indwelling Foley catheter moving in and out of the urethra. This action is responsible for the retrograde movement of bacteria outside the body & into the urethra, bladder, & kidneys increasing preventable infections. With much prevention work globally, the pistoning action of a Foley catheter is now known to be partially or wholly to blame for the attributed $340 million spent in the U.S. on healthcare costs & 13,000 associated deaths making this an immediate global patient safety emergency.
