Presentation Outline Problem Statement Femoral Vein Catheterization and Position of Patient Client Expectations Available Positioners and Current Practices Choosing a Design Progress Now and for the Future.
Problem Statement Design a leg positioner for use in femoral vein catheterization that is optimized for the following functions: Securing a patient’s leg at a set angle If necessary securing the pannus
Femoral Vein Catheterization Catheter inserted distal to inguinal ligament Often used for fluid infusion or cardiac diagnostics Gives access to large blood flow for hemodialysis d. yimg. com/. . . /ls/he/healthwise/n 5551133. jpg
Leg Position Ideal leg position Knee flexed Hip abducted and externally rotated Allows for easier catheter insertion Difficult to keep in position without holding leg
Client Expectations Disposable Does not obstruct operating field Inhibit leg from moving during entire procedure Provide an attachable device to retract the pannus Device does not slip or rotate during procedure
Competition/Patents Manual method – “Nurse Restraint” Patents: 3, 931, 654 4, 730, 609 5, 010, 900 7, 234, 180 None of the patents are similar to our design, or have the same functionality.
Design #1: Foot Holder Cuff attached to opposite leg Insert foot to produce proper angle Angle and length adjustable

Progress so far… Finalized our design Ordered parts this past Monday Still need to decide on some things yet. . Begun discussing rough ideas on attachment devices Hinges, ball and socket
Future Work Go to Home Depot/Menards to look for attachment mechanisms Locking swivel mechanism Construct prototype based on already ordered materials Test completed prototype on simulated catheter procedure
