A far ultraviolet light application device for killing pathogens on tissue and proximate thereto includes a tube that is to be utilized in a medical procedure. A first fiberoptic cable is engaged to a wall of the tube so that a first end of the first fiberoptic cable is positioned proximate to a first terminus of the tube. The first fiberoptic cable has a second end operationally engaged an ultraviolet C light emitter so that ultraviolet C light is emitted proximate to the first terminus of the tube. The first fiberoptic cable directs the ultraviolet C light from the ultraviolet C light emitter so that the ultraviolet C light impinges upon tissue and pathogens proximate to the first terminus of the tube to inactivate the pathogens.

The present disclosure provides a gaming system including an application that can be implemented using a dynamic testing game, wherein the system does not require glasses, goggles, or any other headwear. The system enables a test subject to be screened and treated for vision dysfunctions while engaging with a dynamic video game.

Certain configurations of removable oral devices are described. In some instances, the removable oral device includes a palatal element. In certain configurations, the palatal element may comprise a variable hardness at different areas, e.g., edges can be softer than other areas of the removable oral device. In other instances, the removable oral device may comprise two or more individual palatal elements which together can form the palatal element and permit user adjustment of the oral volume. Various materials used in the palatal element are described. Sensors and other on-board devices are also described.

Dental retraction and isolation devices disclosed herein simultaneously isolate at least a portion of a maxillary dental arch and at least a portion of an opposing mandibular dental arch, along with the gingivae near the gumline, while gently retracting a patient's tongue, cheek and lips. All procedures in operative dentistry and fixed prosthodontics can be performed using these devices, but they are particularly useful where access to the gingiva is necessary or desirable, where a dry field is crucial for bonding success, and/or where occlusion and masticatory movement in a dry field are advantageous. The devices can be deployed in seconds and stay in place without clamps, ligatures or wedges, and because the devices are fabricated from soft, pliable materials, they reduce tissue damage and conform to oral surfaces.

The present invention relates to a lip and tongue retractor (100) comprising in a single central body (200) a central bulkhead (210) and a bridge (230). The central bulkhead (210) is provided with stabilizing rods (220), both resilient and movable between each other, the clearance thereof being maintained by a lock element (400) separated from the lip and tongue retractor (100); whereas the bridge (230) is equipped with a fitting end (231) for coupling to a convex body (300) separated from the central body (200).

The present application discloses a variety of airway sampling devices and associated methods. According to an embodiment, an airway sampling device for taking a sample from a subject's airway is provided with a handle to be gripped by a user when taking the sample and a sampling head carried by the handle, the sampling head comprising a cavity with an opening for entry by the sample and a sample collection membrane located within the cavity for receiving the sample.

An apparatus for mandibular advancement of an oral appliance for use in the treatment of sleep apnea, snoring, and other conditions. The apparatus for mandibular advancement of an oral appliance generally includes a first appliance portion comprising a gear assembly having a drive gear, wherein rotation of the drive gear linearly displaces links. The appliance also has a second appliance portion with a link-engaging members, wherein the links exert a force on the link-engaging members when they are linearly displaced, and wherein the force causes the second appliance portion to be displaced relative to the first appliance portion.
