  8. Abstract The UW Children’s hospital currently has no organizational system for IV tubing.  IV lines extend from multiple syringe pumps to one patient and become entangled, especially during transport.  A prototype was assembled in which a length of IV tubing is wound around a spool. Automatic recoil is controlled by a constant force spring-loaded system that allows for patient movement by retracting or extending extra lengths of IV tubing.

  9. Problem Statement • The goal of this project is to create an IV tubing organizer to prevent the entanglement of several IV lines, while maintaining the functionality of an IV tube. Use of this device will increase both patient safety and hospital efficiency.

  10. Background Information • Pediatric Patients • Intensive care patients • Connected to multiple IV lines • Causes confusion and entanglement • Places patient at risk • Consumes staff time • Increased risk during transport

  11. Design Constraints • Safe for patient • Does not occlude IV line • Lightweight and inexpensive • Disposable, but re-loadable • Need not be sterile • Non-magnetic materials • Easy to operate

  12. Preliminary Design • Lego Model • Tubing ends: one fixed, one adjustable • Clamping feature • Manual operation • Uses handle to coil tubing

  13. Chosen Design • Spring recoil mechanism • IV tubing in constant tension • No manual retraction • Framework consists of connected plastic discs • Rotating core To patient Constant force spring To syringe pump

  14. Prototype Construction • Acquired materials • Plexiglass • Plastic cylinder • Extension spring • Epoxy • Initial prototype constructed • Functional prototype • Piecewise construction • Addition of spring

  15. Functional Prototype Side view schematic

  16. Functional Prototype • Composed primarily of plastic • Inexpensive • Spring exerts a force of ~⅜ lb on IV tubing • Easy to use

  17. Constant Force Springs • Type of coiled extension spring • Maintains a constant force regardless of extension length • Avoids linear force build-up • Reduces risk of uncontrolled recoil at larger extensions http://www.trakar.com/tr_constant.htm

  18. Cost Analysis • ⅛” plexiglass sheet (0.25 ft2) =$0.55 • 1 ½” diam. plexiglass tube (¾” long) =$0.81 • Constant force spring =$2.00 • ⅛” x 1 ½” nylon screws & nuts (3) =$0.70 • ⅛” x ½” nylon screw & nut (1) =$0.10 • ⅛” x ⅜” nylon screw & nut (1) =$0.10 • Plastic welder epoxy (1 oz.) =$0.75 Total=$5.01

  19. Future Work • Increase diameter of sides to prevent obstruction of IV tubing • Research fluid dynamics • Determine possible flow restrictions • Determine FDA-approved materials • Use color coding for organizational purposes • Determine placement of multiple devices • Receptacle or clamps • Testing in the hospital environment • Mechanics of design • Interaction with MRI machine
