摘要： Methods, systems and devices for monitoring patient orientation, direction, altitude and location to determine the need for turns as well as to detect impending or actual bed exits or falls. A patient-worn sensor communicates with at least one host server through a mesh network of relay antennae to provide data representative of various patient characteristics. The sensor comprises one or more of an accelerometer, a magnetometer and an altimeter, along with optional other sensors. Various user interfaces are provided for managing patient care using the information developed by algorithms processed at the server based on data received from the patient sensors.

摘要： A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment. In some embodiments, the system can further include a support surface having one or more sensors incorporated therein either in addition to sensors affixed to the patient or as an alternative thereof. The support surface is, in some embodiments, capable of responding to commands from the host for assisting in implementing a course of action for patient treatment. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capactive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.
摘要翻译：用于监测包括压力性溃疡，压力引起的缺血和相关医疗状况在内的医学状况的系统包括至少一个适于检测一个或多个患者特征的传感器，其包括至少位置，方向，温度，加速度，湿度，阻力，应力，心率呼吸频率和血氧饱和度，主持人处理从传感器接收的数据和历史患者数据，以开发对患者状况的评估和建议的治疗过程。在一些实施例中，系统还可以包括除了固定在患者上的传感器之外还具有一个或多个传感器的支撑表面，或者作为替代。在一些实施例中，支撑表面能够响应来自主机的命令来帮助实施用于患者治疗的动作过程。传感器可以包括双轴向或三轴加速度计，以及电阻式，感应式，主动式，磁性和其它感测装置，这取决于传感器是位于患者还是支撑表面上，以及用于什么目的。
