Abstract: Various embodiments of a swab device, system, and method are provided for measuring and assessing saliva flow in the mouth of a person. In one embodiment, a system includes a swab device and a measuring device. The swab device includes a handle portion and a swab portion, the handle portion being elongated to extend between a proximal end and a distal end. The swab portion is coupled to a distal portion of the handle portion and is sized and configured to collect saliva from the mouth. The measuring device is sized and configured to measure an amount of the saliva collected with the swab portion, the measuring device including a nesting portion integrated therewith. Such nesting portion of the measuring device is sized and configured to receive the proximal end of the handle portion of the swab device to measure the saliva collected therewith.

Abstract: An apparatus comprising a first X-ray image system and a second X-ray image system. Each X-ray image system includes a devices for emitting X-rays and a radiation receiving device located in the direction of the radiation. These are disposed, on receiving radiation, to emit signals to a TV-monitor. The two X-ray image systems form an integral X-ray image unit which is supported by a carrier device. By means of a connection device, the X-ray image unit is movably connected to the carrier device and, in association with the connection device, the X-ray image unit is movably journalled for altering the angle of inclination of a plane through the center axes of the rays for the two X-ray image systems.
