  • Publication number: 20210177679
    Abstract: A patient support apparatus includes a frame supported relative to a floor, the frame configured to support a deck for supporting a patient thereon, and a lift assembly for raising or lowering the frame relative to the floor. The lift assembly includes lifting legs coupled to the frame and an actuator with a body and an extendible member. The actuator is mounted to one of the legs, rather than the frame, and mounted for linear movement with respect to the one leg, with the linear movement translated into rotational movement of the other leg by a link and crank arm arrangement.

  • Patent number: 10909964
    Abstract: A person support apparatus, such as a bed, cot, stretcher, or the like, includes an active noise cancellation device configured to generate a noise cancelling sound wave that is designed to cancel a noise sound wave. The active noise cancellation device may include speakers and a microphone. In other embodiments, the person support apparatus includes a sound emitting component and a transmitter adapted to send out a notification signal prior to activation of the sound emitting component. The notification signal provides information about a characteristic of the sound to be emitted by the sound emitting device. The recipient of the notification signal may then use the signal to cancel the sound that is to be emitted. In some embodiments, the person support apparatus acts as a conduit for notification signals of upcoming sounds, receiving and forwarding such notification signals from and to other devices.

  • Publication number: 20210020307
    Abstract: A system for providing healthcare information regarding a patient's hospital visit includes a health information application that operates on a plurality of electronic devices. The application displays first data regarding the patient's visit; processes information indicating a current location of the mobile electronic device; and displays second data regarding the patient's visit that is delayed until the mobile electronic device crosses a boundary of a geo-fenced area. The electronic device may also communicate with a bed server at the healthcare facility and authorize the bed server to automatically send a notification message to a second mobile electronic device associated with the patient's friend or family member based on the patient's sleep status and/or movement into or out of bed. The application may also gather and process data useful to healthcare administrators, such as HCAHPS survey scores, status data for medical devices, equipment servicing information, and other information.
