  • RADAR SENSORS FOR PATIENT MONITORING
    Publication number: 20240122502
    Abstract: One or more radar sensors can be used to monitor patients in a variety of different environments and embodiments. In one embodiment, radar sensors can be used to monitor a patient's breathing, including monitoring of tidal volume, chest expansion distance, breathing rate, etc. In another embodiment, a patient position can be monitored in a patient bed, which can be used as feedback for control of bladders of a patient bed. Additional embodiments are described herein.

  • METHOD OF MANUFACTURING RFID TAGS
    Publication number: 20220362067
    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.

  • TOPPER WITH TARGETED FLUID FLOW DISTRIBUTION
    Publication number: 20220183474
    Abstract: A topper (38) for a bed extends in longitudinal and lateral directions and includes a fluid flowpath (60) for channeling fluid through the topper from an inlet (62) to an outlet (64). The flowpath is configured to distribute the fluid to a preferred target region (50) of the topper. A bed which includes the topper has a blower (72) connected to the topper inlet for supplying air (88) to the flowpath.

  • MATTRESS HAVING SELECTABLE PATIENT WEIGHT VALVE, INDUCTIVE POWER, AND A DIGITAL X-RAY CASSETTE
    Publication number: 20200375551
    Abstract: A patient support apparatus may include a foam frame defining a space. A bladder assembly may be positioned in the space. The bladder assembly may include a plurality of foam filled bladders. Each of the foam filled bladders may be interconnected by a manifold. A plurality of mutually exclusively selectable pressure relief valves may be provided to release air from the bladder assembly.
