    • A patient support apparatus comprising a wireless control system is provided. The wireless control system includes a device for sending a wireless signal, a receiver for receiving the wireless signal, and circuitry for processing the wireless signal. The circuitry may have a learn mode in which a device is associated with the control signal to the exclusion of commands from other devices not associated with the circuitry. Also, the device may transmit a wireless signal redundantly over a plurality of frequencies. The control system may choose a signal frequency and receiver combination to maintain a quality signal. The device may be limited provide commands to operate a function of the patient support apparatus only when the function has been enabled through a sequence of input activations. The wireless control system is capable of controlling any of a number of functions associated with the patient support apparatus. Illustratively, the control system operates a patient repositioning apparatus. The repositioning apparatus includes a retractor, a tether coupled to the retractor and configured to be retracted by the retractor, and a sheet attachment device coupled to the tether opposite the retractor, the sheet attachment device configured to engage a sheet on the patient support apparatus. The sheet attachment device includes a user interface configured to provide wireless inputs to the retractor. The retractor includes a controller configured to receive inputs, process the inputs, and provide outputs to activate the retractor.
    • 提供一种包括无线控制系统的患者支持装置。 无线控制系统包括用于发送无线信号的装置,用于接收无线信号的接收机和用于处理无线信号的电路。 电路可以具有学习模式,其中设备与控制信号相关联,以排除来自不与电路相关联的其他设备的命令。 此外,设备可以在多个频率上冗余地发送无线信号。 控制系统可以选择信号频率和接收机组合来保持质量信号。 只有当功能已经通过输入激活序列启用时,该设备可能被限制地提供用于操作患者支持设备的功能的命令。 无线控制系统能够控制与患者支持装置相关联的多个功能中的任何一个。 说明性地,控制系统操作患者重新定位装置。 重新定位装置包括牵开器,联接到牵开器并被构造成由牵开器缩回的系绳,以及联接到与牵开器相对的系绳的片材附接装置,所述片材附接装置构造成与患者支撑装置上的片材接合。 片材附接装置包括被配置为向牵开器提供无线输入的用户界面。 牵开器包括被配置为接收输入,处理输入并提供输出以激活牵开器的控制器。
