    • A portable multi-purpose device for monitoring patient movement in a number of different ways. The device includes a data processor programmed to respond to signals from multiple different external sensors that easily connect to the device through a jack in the device housing. If patient movement beyond a limit is sensed, the device generates an alarm for an attendant. To sense the different types of patient movement, one sensor is simply substituted for another. Examples of sensors include tether, door monitoring, and weight sensors. The device protects against unauthorized disabling of the sensors by sounding an alarm if a sensor is unplugged from the device impermissibly. The device provides power to sensors that require power to operate, reducing the need for additional power sources. The device also stores patient data (e.g., number of alarms, time before attendance response, etc.) during a given time period for evaluating a patient's care.
    • 一种用于以多种不同方式监测患者运动的便携式多用途装置。 该设备包括被编程为响应来自多个不同外部传感器的信号的数据处理器,其通过设备壳体中的插孔容易地连接到设备。 如果感觉到超出极限的患者运动,设备会为服务员产生警报。 为了感测不同类型的患者运动,一个传感器只是替代另一个传感器。 传感器的示例包括系绳,门监控和重量传感器。 如果传感器不可忽视地从设备上拔下来,该设备将通过发出警报来防止未经授权的传感器禁用。 该设备为需要电源供电的传感器提供电源,从而减少对附加电源的需求。 该设备还在给定时间段内存储患者数据(例如,警报数,出勤响应时间等)以评估患者的护理。

    • A patient monitoring system utilizes a transmitter associated with each patient. The transmitter is worn by a patient and includes sensors operative to monitor vital signs of the patient. The transmitter transmits an allocated RF frequency which is particularly associated with that patient. A series of antennas are incorporated in a building, each antenna having its own signature signal. As the patient moves throughout the building, the antennas pick up the signals from the patient's transmitter and combines the antenna signature signal with the transmitted patient signal. This combined signal is then analyzed at a central location to determine the exact location of the patient due to the antenna signature signal which is modulated on the transmitted patient signal. Transmitted patient data is also decoded at the central station to provide a signal indicative of the vital signs of the patient.
    • 患者监控系统利用与每个患者相关联的发射器。 变送器由患者佩戴,并且包括用于监测患者的生命体征的传感器。 发射机发送与该患者特别相关的分配的RF频率。 一系列天线被并入建筑物中,每个天线具有其自己的签名信号。 当患者移动到整个建筑物时,天线拾取来自患者发射器的信号,并将天线签名信号与发送的患者信号组合。 然后在中心位置分析该组合信号,以确定由于在发送的患者信号上调制的天线签名信号而导致的患者的确切位置。 传输的患者数据也在中心站解码以提供指示患者的生命体征的信号。
