Abstract
This invention identifies cavitation as a damaging problem in catheterizing, such cavitation occurring upon removal of the catheter from the urethra. This invention shows venting the catheter tip to reduce cavitation related damage to the urinary track upon catheter removal. This invention discloses methods to reduce or prevent cavitation damage to portions of the urinary track This invention shows a vent to reduce partial vacuum formation leading to cavitation damage can be plastic “trimmer lines” used in lawn trimmers also called “weed eaters”.
Claims13
A cavitation reduction operative between a catheter and a body parts interface region when the catheter is removed from the interface region to reduce &image to the body parts.
A method of catheterizing comprising venting air or other fluid to a body parts region prior to or coincident with removal of the catheter to prevent or reduce cavitation.
A method of catheterizing comprising a fluid vent of the catheter tip prior to or coincident with catheter removal to prevent a partial vacuum formation at the catheter tip.
