Abstract: Embodiments disclosed herein are directed to a fluid collection system that can relax dependent loops. The system includes a drainage tube and a container, the tube is slidably engaged with an aperture of the container to allow a portion of the tube to be inserted therein. Embodiments can include a seal to prevent fluids or gases escaping, and a sleeve to mitigate introducing CATTTI causing agents into the system. Embodiments can also include a slide assembly to pull a proximal portion of the tube into the collection container. Shortening a communication length of the tube relaxes dependent loops, which can provide a substantially continuous negative incline between the distal end and the proximal end of the drainage tube. Relaxing dependent loops in this way can mitigate urine pooling within the drainage tube that can harbor CAETTI causing agents.

Abstract: Embodiments disclosed herein are directed to systems and methods of drainage tubes displaying differing mechanical properties along an axial length. These drainage tubes can be provided as integrally formed tubes or as modular systems and can be provided as part of a kit. The differing mechanical properties allows a user to position the tube and to prevent the formation of dependent loops, which allow fluid to pool therein. Proximal portions of the tube can display rigid or malleable properties to maintain a negative incline, or be positioned and remain in position until repositioned. Modular tube kits allow a user to select different mechanical properties along an axial length and modify an overall length of the tube to suit the user's needs.
