System for integrally measuring clinical parameters of the visual function including a display unit (20) for representing a scene with a 3D object having variable characteristics such as virtual position and virtual volume of the 3D object within the scene; movement sensors (60) for detecting the user head position and distance from the display unit (20); tracking sensors (10) for detecting the user pupils position and pupillary distance; an interface (30) for the user interaction on the scene; processing means (42,44) for analysing the user response based on the data coming from sensors (60,10) and the interface (30), with the characteristics variations of the 3D object; and based on the estimation of a plurality of clinical parameters of the visual function related to binocularity, accommodation, ocular motility and visual perception.

A tongue maneuvering apparatus has a body, a first attachment site, and a second attachment site. The body includes a bulb, a tongue receiving portion, a tongue aperture, and a slot. The body may be a thin, pliable plastic, such as silicone, so as to create proper suction with the tongue when inserted into the tongue receiving portion. A healthcare provider is able to extend and manipulate a patient's tongue so as to clearly view the mouth and throat without activating the gag reflex and maintaining control of the tongue by the provider.

This drowsiness estimating device estimates a subject's drowsiness from a time-series signal of the subject's eye-openness width. A filtering circuitry filters the time-series signal of the eye-openness width to eliminate signal changes due to the subject blanking and outputs the filtered time-series signal of eye-openness. A feature calculator calculates a feature from at least the filtered time-series signal of the eye-openness width. A drowsiness estimator estimates a drowsiness evaluated value from the feature and outputs an estimated result. The feature calculator includes at least a first feature calculation circuit that calculates a variation of the filtered time-series signal of the eye-openness width within a feature calculation window width and outputs the variation as a first feature.

A laryngopharyngoscope retractor system including: a plurality of components including: a base frame with a coupling region and a spatula holder that is adjustable in terms of position and orientation by way of adjusting screws; a spatula that is releasably fastenable in the spatula holder; two cheek holder adapters that are releasably fastenable to the base frame; and two cheek holders, each of which is releasably fastenable to a respective cheek holder adapter, wherein one or more of the base frame, the spatula holder, the spatula, the cheek holder adapter and the cheek holder, in the respective regions provided for the releasable connection to another one of the plurality of components have a visible unique code that corresponds to the corresponding regions on the other of the plurality of components.

A system for laser-based medical use and laser-based oral surgery. The system includes an elongate handle having a proximal end and a distal end; a (e.g., disposable, selectively removable) functional element disposed at the distal end of the elongate handle; and an integral, soft coating material formed about, so as to cover, the functional element and the distal end of the elongate handle. In some implementations, the elongate handle includes a rigid (e.g., polycarbonate) portion and a soft (e.g., thermoplastic elastomer) portion for improving a user's grip of the elongate handle.
