  • Patent number: 6359190
    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.

  • Patent number: 6262331
    Abstract: An absorbent article adapted to be worn about the lower torso of a wearer. The article includes a liquid-impervious, flexible backsheet adapted to face outwardly relative to the body a wearer, a liquid-pervious topsheet adapted to face the body of the wearer, and an absorbent core positioned between the backsheet and the topsheet. The topsheet is preferably elastically extensible and includes a plurality of slits or cuts that extend through the topsheet material and that enlarge to define a plurality of openings in the topsheet when it is subjected to tensile forces as it is worn. The openings permit solid and semi-solid bodily exudates to pass through the topsheet to the absorbent core as the diaper is worn. Upon removal of the diaper from the body of the wearer the tensile forces within the topsheet are relaxed, thereby causing the openings in the topsheet to close and substantially conceal from view the bodily exudates that have passed through the topsheet.
