Abstract: An otoscope and method for visualizing compliance of the tympanic membrane in response to a pressure stimulus. The otoscope includes a handle, a housing, a laser assembly configured to selectively project a grid array of dots on a tympanic membrane of a patient, a camera configured to selectively capture activity of the tympanic membrane, a pressure transducer configured to selectively apply a stimulus to the tympanic membrane, a display pivotably coupled to the handle, and a controller. The display is configured to display the tympanic membrane in true color and a two-dimensional interpolated surface plot representing activity of the tympanic membrane in response to the stimulus.

Abstract: An otoscope includes a handle, a housing coupled to the handle and having an inlet, a laser assembly at least partially enclosed within the handle and configured to selectively project, through the inlet, a grid array of dots on a tympanic membrane of a patient, a camera supported by one of the handle or the housing and configured to selectively capture activity of the tympanic membrane, a pressure transducer supported by one of the handle or the housing and configured to selectively apply a stimulus to the tympanic membrane, a display pivotably coupled to the handle, a controller in communication with laser assembly and the display, and a microprocessor in communication with the controller, the camera, and the display. The display is configured to display the tympanic membrane in true color and a two-dimensional interpolated surface plot representing activity of the tympanic membrane in response to the stimulus.

Abstract: Improved facemask designs are disclosed herein. The improved facemask is designed to provide a sucking airflow that sucks aerosolized particles emitted from a person's mouth towards a filtration unit. By providing this sucking airflow, medical personnel can work on the user's mouth and facial area without worrying about breathing in the aerosolized particles. The facemask includes a covering portion that covers a user's nose and mouth. The facemask includes a central lumen that is configured to permit access to the user's nose and/or mouth. The facemask further includes an access port configured to enable airflow communication between the covering portion and a bilateral vacuum. Airflow is directed away from the central lumen towards the bilateral vacuum. By directing the airflow in this manner, aerosolized particles emitted from the user's mouth are removed in an effective amount to decrease expulsion of the aerosolized particles outside of the vacuum facemask.
