Training Simulator for Thoracentesis

This Phase II proposal describes the development of a comprehensive, portable computer-based simulation for training in needle thoracentesis. The system will include refined hardware, underling software, and educational content created to meet needsdefined by clinical faculty. Proposed technical advances include: incorporating a software framework that greatly enhances the simulation's flexibility to users; developing ten virtual patient cases that can be rotated and viewed in transparency; usingImmersion's patented haptic computer mouse technology in a laptop touchpad for simulation of patient palpation tasks; developing a virtual needle that floats freely in space and provides multi-axis tactile force feedback during simulated insertion;simulating the experience of striking bone (rib) with a needle; and creating an anatomical reference model of the human torso. Three learning modes will be available to users of the completed product: teaching mode, practice/rehearsal mode, and testingmode. Structured evaluation will help guide system development throughout the proposed project period, and two proposed evaluation studies will demonstrate first feasibility (option cost), then construct validity of the completed simulator.The proposedsimulator represents the first ever virtual reality training device for thoracentesis. Its combination of portability, flexibility and realism, including the important tactile experiences that accompany the procedure, promise significant advances to thecurrent training paradigm. Skills acquisition, maintenance, and evaluation would be available in one device, and without risk to patients or learners. The particular demands of military training would be well served by the proposed system due to itsportability, its customizability, and its strong emphasis on trauma cases. Implementation could bolster military readiness through faster and more streamlined training, leading to better clinical outcomes and shortened recovery times. The proposedtechnological advances also will lead to the production of commercially viable products by a company with a proven record of success at marketing and selling medical simulators. Training benefits will accrue across the clinical spectrum, including bothcivilian and military applications.
