From: Preventing inadvertent drain removal using a novel catheter securement device
Inspiration of a proposed securement device from sailing and tech industries—pictured are the quick-release unit (QR, a) and securement component (SC, b). The QR is placed in-line with the catheter and does not allow internal transmission of forces great enough for dislodgement. A percutaneous catheter is wound around the SC, which is adhered to the body and prevents migration of the catheter. See supplemental video 1 which demonstrates an animated model of the device in action. The inspiration for the QR draws from current technology solutions for a safe power supply connection (c), and the inspiration for the SC is inspired from sailing winches, which also employ the Capstan principle (d).
