Abstract: A simulator trains for hemorrhage control using hemostatic agents, tourniquets, and/or other hemorrhage control techniques in a simulator that works with a wide variety of existing human surrogates. The simulator merges a live video feed of the surrogate and trainee's hands (or objects interacting with the surrogate) with a computer-generated visual representation of the wound and hemorrhaging blood to provide an immersive display experience to the trainee without requiring different surrogates for different simulated wounds. The trainee may wear pulse-generating glove(s) that simulate the patient's pulse where the trainee's finger tip contacts the surrogate. A sensorized substrate (e.g., load sensors, haptic output generators) may automatically be moved between the trainee and the surrogate to sense interaction with the surrogate and provide haptic feedback. The substrate may replace the surrogate altogether. The simulator may alternatively simulate events and objects other than wounds and humans.

Abstract: A microsurgery simulator simulates various microsurgical procedures (e.g., nerve reapproximation, ear drain deployment) that utilize a surgical microscope. A surrogate surgical microscope includes a mobile device and an eye piece. A physical surrogate surgical interface represents an interface between a user and a simulated surgical scenario. Sensors sense the user's manipulation of the surrogate surgical interface. A surgical simulation generator generates a real time 3D surgical simulation based on the sensed manipulation. The generator renders the real time surgical simulation into a real time computer graphics generated video representation that is displayed on a screen of the mobile device. A processor of the mobile device is configured to perform at least a portion of a computational analysis that is used to generate the real time computer graphics generated video representation.

Abstract: A system, method and device for simulating a medical procedure include a haptic mechanism controllable to provide feedback to a user manipulating a medical device. In an embodiment, a pair of three degree of freedom haptic devices are coupled to provide six degree of freedom measurement and force/moment feedback to the user. The six degree of freedom haptic device may be configured to provide different resolutions for different degrees of freedom, depending on simulation requirements. In an embodiment, a load cell is used to provide higher resolution in a dimension determined to be of greater criticality to realistic simulation.

Abstract: A 3D surface wound, injury, and personal protective equipment (PPE) data entry system provides an easily usable graphical user interface through which an examiner can objectively record data relating to surface wounds and injuries sustained by a subject human, as well as PPE used when the wounds/injuries were sustained. The system includes a 3D human model onto which the examiner draws the surface wound(s) and/or damage to the PPE. The subject human's record is stored in a database of similar records. The database records comprise quantifiable, objective data that is easily compared and analyzed. An analysis tool can aggregate a selected population of human subjects within the database to create wound density information that can be statistically analyzed and/or displayed on a standard 3D human model. Such objective wound density information may facilitate improved medical and/or tactical training, and improved PPE design.

Abstract: A simulator simulates interaction between a surgical tool and biological tissue, providing real time visual and/or haptic feedback. The simulator receives tool input device information representative of a user's movement of a physical tool. The simulator simulates, based on the tool input device information, an interaction between the simulated tool and simulated biological tissue. The simulator uses multiple computational threads, some of which provide their calculations to interrelated threads for use. The simulator displays a visual representation of the simulated interaction between the simulated tool and the simulated biological tissue and provides haptic feedback to the user. The threads may operate asynchronously and have different spatial and/or temporal resolutions. Threads may be selectively activated and deactivated. Threads may move their spatial coverage.

Abstract: A limb hemorrhage trauma simulator provides didactic and hands-on training for the prehospital treatment of a limb trauma victim. The simulator realistically simulates a wounded limb, providing simulated pulse and hemorrhage blood flow. The simulator provides a simulated scenario in which the wound occurred. The student then responds to the scenario by treating the limb via direct pressure, tourniquet, and/or wound analysis. The simulator modifies hemorrhage blood flow and pulse in response to direct or tourniquet pressure applied to the limb. The simulator records the student's actions to provide feedback and grade the student's response.
