Advanced Surface System For Central Venous Catheter Insertion Training

An advanced surface for Central Venous Catheterization (CVC) training and evaluation was designed using sensorization techniques, including the use of a hall effect sensor array to measure the insertion depth of a catheter. The sensor array was tested for accuracy in both static and dynamic scenarios, and was found to be sufficiently accurate; measuring position with an accuracy of +/- 1.1 mm on average. The highest deviations in measured positions were located at the extreme ends of the array where calculations rely on only a single sensor. The maximum deviation in measured position was found to be 3.5 mm. This low-cost system of catheter measurement has the potential to improve feedback and assessment of CVC training.
