  • Patent number: 10413465
    Abstract: A patient support apparatus, such as a hospital bed, includes an alert light assembly or an alert light module having separate zones that are individually illuminated to convey information regarding respective alert conditions. The zones each have indicia related to a particular condition of the patient support apparatus. The illuminated zones are each sufficiently large so as to be seen from afar, such as on the order of ten feet or more. Alternatively or additionally, a GUI of the patient support apparatus displays alert indicia as part of a screen saver. Further alternatively or additionally, the patient support apparatus illuminates an alert light in a manner indicating an optimal time for taking a patient's vital signs.

  • Publication number: 20190254583
    Abstract: A system for detecting an incontinence event includes a pad which is deployable on a mattress and which, as deployed, has a first conductor and a second conductor and in which the first conductor and the second conductor are not in electrical communication with each other. The system also incudes an RFID reader subsystem having a processor and an array of two or more spatially distributed antennas. The system is adapted to A) command transmission of energy from the antenna array at a variety of powers and at various frequencies, B) monitor the antenna array for a return signal resulting from the spatially and temporally varying transmission, and C) communicate a WET or DRY status to a destination. The WET or DRY status depends on a moisture status indicator of the return signal.

  • Patent number: 10357414
    Abstract: A system for changing the width of a person support apparatus includes a bed controller for receiving a command signal indicating a command for width alteration, a first motor controlled by the bed controller for driving an extension of a first deck section of the support apparatus thereby altering the width of the first deck section, and a second motor controlled by the bed controller for driving an extension of a second deck section of the support apparatus thereby altering the width of the second deck section. The bed controller controls the first motor and the second motor in a manner that causes the first deck section to reach a first deck section width alteration limit at a first time and the second deck section to reach a second deck section width alteration limit at a second time, wherein the first time and the second time are not equal.

  • Patent number: 10349881
    Abstract: A system for detecting an incontinence event includes a pad which is deployable on a mattress and which, as deployed, has an open circuit comprised of a first conductor extending from a first terminal of an RFID inlay, and a second conductor extending from a second terminal of the RFID inlay. The system also includes an RFID reader subsystem having an array of two or more spatially distributed antennas. The detection system commands spatially and temporally varying transmission of energy from the antenna array at a variety of powers and frequency settings. The detection system monitors the antenna array for a return signal resulting from the transmission. The return signal has a moisture status indicator which indicates whether or not liquid is present on the pad. The detection system also causes communication of a WET or DRY status to a destination. The reported WET or DRY status depends on the moisture status indicator.

  • Publication number: 20190091074
    Abstract: An incontinence detection system monitors an area for moisture events and wirelessly transmits moisture-related information to one or more notification devices. The system has a pad that includes a substrate and one or more sensors supported by the substrate. The sensor(s) emit wireless signals indicative of the moisture-related information. A sensor event communication system forwards the sensor signals to another device, such as a notification device. Portions of the system are included in a patient support apparatus, such as a bed.

  • 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.

  • Publication number: 20190008711
    Abstract: A slingbar assembly for supporting a patient includes at least a first slingbar. The first slingbar includes a load bearing frame, at least two spanwisely fixed spacers attached to the frame on opposite sides of a centerplane, and a hub attached to the frame spanwisely between two of the spacers. The slingbar assembly also includes a a strap assembly engaged with the hub. The hub is operable to increase or decrease a working length of the strap assembly. Another embodiment of the slingbar assembly includes a second slingbar substantially the same as the first slingbar, and a connector extending longitudinally between and connected to the slingbars. The connector includes an attachment fixture selectively positionable along the length of the connector so that when the slingbar assembly is supported by a support structure the position of a patient's center of gravity relative to the slingbar assembly can be adjusted.

  • Publication number: 20180325744
    Abstract: An incontinence detection pad has an RFID tag in which an authentication code, such as an electronic product code (EPC), is stored. A reader in wireless communication with the RFID tag of the incontinence detection pad verifies that the incontinence detection pad is an authorized detection pad. Thus, unauthorized incontinence detection pads that do not have the proper authentication code are not able to be used in an incontinence detection system.

  • Publication number: 20180289572
    Abstract: A method of determining information about a device includes the steps of 1) acquiring an image of at least a portion of the device, 2) comparing the information content of the image to the information content of at least one record of a library, and, 3) if the comparison is positive, reporting that the device is in the possible state represented by the library record. A method which depends on calculations based on the acquired image rather than on comparison of the information content of the image to the information content of one or more library records is also disclosed. A system for determining the state of the device is also disclosed.

  • Publication number: 20180039743
    Abstract: Systems and methods of associating beds and/or rooms and/or patients are provided. One system and method involves using a signature of emitted light to determine a location of a patient bed in a healthcare facility. Another system and method involves reading a bar code from an array of redundant bar codes. Still another system and method involves manually entering location information on a graphical user interface of a patient bed for subsequent transmission. A further system and method involves sending bed ID and location ID along parallel paths from two independent circuits on a patient bed for receipt by two different transceivers and ultimately by two different remote computers that cooperate to associate the bed ID with the location ID. Still a further system and method involves using circuitry on a bed to mutate a received location ID and a bed ID into a single unique mutated ID such as by adding the location ID and bed ID and then performing a hashing operation.
