  • Patent number: 10219725
    Abstract: A patient support apparatus includes a control system that measures changes in the pressure of one or more zones of a patient supporting surface and utilizes the changes in pressure to determine the mobility of a person supported on the patient supporting surface. The mobility of the person may be measured using one of several methods. The mobility measurement results in the determination of a mobility score. The mobility score is graphically displayed on a user interface that is interactive and allows a user to view additional information besides the mobility score.

  • Publication number: 20190060137
    Abstract: An absorbent article has one or more fluid filter layers to inhibit electrode traces from being exposed to low volumes of fluid to reduce the number of false positives that are indicated by an RFID tag of the incontinence detection pad. An antenna inlay has a sacrificial trace portion to permit testing for proper operation of an RFID chip electrically coupled to the antenna inlay. After testing, the sacrificial trace portion is severed. A fluid barrier layer blocks fluid from reaching portions of electrode traces that are located on a backsheet outside a periphery of an absorbent core of an incontinence detection pad. The power at which an antenna transmits to wirelessly energize a passive RFID tag of an incontinence detection pad is controlled to reduce the number of false positives indicated by the RFID tag.

  • Patent number: 10127788
    Abstract: A person support apparatus supports a person in a laying-down or a seated position. One or more body-mounted sensors detect changes in the position of the person relative to a reference. A control system receives output from the body-mounted sensor or sensors through a remote coupling. The control system uses patient position information obtained from the body-mounted sensors to determine whether the person has experienced a change-in-position and/or a change-in-activity event. Alternatively or in addition, the position of the person situated on a person support apparatus is detected using one or more sensors that are not body-mounted, but rather are coupled to the person support apparatus or to another component of a patient support system. The patient position information is used to estimate the patient's torso angle. The estimated torso angle is used to assess the patient's condition.
