  • Patent number: 11727828
    Abstract: A training system uses a physical model of a head and neck with a first tracker, a second tracker on a physical laryngoscope model, a third tracker on a physical endotracheal tube model, and a fourth tracker on a VR goggle; the system uses the trackers to determine positions of the physical models. A simulation system has corresponding digital 3D models of a laryngoscope, an endotracheal tube, and an airway, the airway including 3D models of surfaces of tongue, epiglottis, larynx, pharynx, and trachea. The physical model locations are registered to the digital models. In embodiments, the physical laryngoscope model has sensors measure strain or pressure along its blade and the simulation system has instructions to distort the digital 3D model of the airway according to readings of the sensors. The system can render the digital 3D model viewed from the VR goggle or a camera of the laryngoscope.

  • Patent number: 11375985
    Abstract: An anatomical model includes a first container, a second container disposed within the first container, and a third container disposed within the second container. The second container and the third container simulate components of kidney anatomy, and the model includes ballistics gel to improve echogenicity during an ultrasound-guided training procedure using the model.
