    摘要： The present invention relates to a wetness monitoring system that includes a data collection device that sends wetness measurement data to a central computer that detects changes in wetness measurement data caused by the presence of urine or other dielectric fluids. The data collection device includes a semi-reusable sensor and reusable data collector that are worn on a garment of the person. The data collector includes an internal power source so that the person can live a normal ambulatory life. The data collector has an electrical circuit that uses the changing resistance characteristics in the sensor to gather wetness measurement data. The data collector periodically generates and transmits a signal containing the actual wetness measurement data. The signals are coded to identify the particular data collector or person sending the signal. The data collector is programmed to conserve power by sending signals less frequently during periods when the sensor is clearly dry. Signals are sent more frequently when the sensor is damp or a wetness event may have occurred. The central computer receives the signals containing the wetness measurement data and compares the measurement data to an adjustable wetness sensitivity level to determine if a wetness event has occurred. When the central computer determines that a wetness event has occurred, the computer displays the name of the particular person wearing the data collector and the approximate time that the wetness event occurred. The system then pages an appropriate healthcare worker to inform them that the particular individual needs attention and tracks the approximate response times to ensure that the patient is continuously receiving prompt care.

    摘要翻译： 湿度监测系统技术领域本发明涉及一种湿度监测系统，其包括：数据收集装置，其将湿度测量数据发送到中央计算机，其检测由尿液或其它介电流体的存在引起的湿度测量数据的变化。 数据采集​​装置包括穿戴在人的衣服上的半可再用传感器和可重复使用的数据收集器。 数据采集​​器包括一个内部电源，使人能够正常行走。 数据采集​​器具有使用传感器中电阻变化特性的电路来收集湿度测量数据。 数据收集器周期性地产生并发送包含实际湿度测量数据的信号。 信号被编码以识别发送信号的特定数据收集器或人。 数据采集​​器被编程为通过在传感器清洁干燥的时段期间较少频率地发送信号来节省功率。 当传感器潮湿或可能发生潮湿事件时，信号会更频繁地发送。 中央计算机接收含有湿度测量数据的信号，并将测量数据与可调湿度敏感度水平进行比较，以确定是否发生了湿度事件。 当中央计算机确定发生湿度事件时，计算机显示佩戴数据收集器的特定人物的名称以及湿度事件发生的大致时间。 然后，系统向适当的医护人员提供通知，告诉他们特定个人需要注意并跟踪大致的响应时间，以确保患者持续接受提示。
