Abstract
A device adapted to measure the volume of a body cavity including a base, a sensor adapted to detect when a body cavity of the wearer reaches a predetermined volume and a signal mechanism. The sensor is moveably mounted on the base so as to facilitate aiming of the sensor toward the body cavity. The signal mechanism is adapted to provide a signal once the predetermined body cavity volume is reached. Alternatively, the device may comprise a first sensor and a second sensor which are oriented differently toward the body cavity and which each measure a distance between the front wall and the back wall of the body cavity. The device also includes a signal mechanism which provides a once a predetermined volume of the body cavity is reached, wherein the volume is calculated based on the greater of the distances measured between the front wall and the back wall of the body cavity.
