Low Cost Mattress Sensor for Body Position Monitoring

描述（由申请人提供）：该计划将开发一种低成本的传感器垫，以监测个人？睡觉时的身体姿势。目前，在没有任何电线或传感器附接到人的情况下监测床上的身体位置的唯一系统被设计用于压力的高分辨率分析和压力分布的变化，因此使用200多个传感器，并且需要昂贵且复杂的系统。一个低成本的系统，可以识别近似的身体位置，或更重要的是身体位置的变化将是一个有价值的工具，在研究和临床应用。本提案的目的是测试和确定识别体位变化所需的最少数量的传感器，并生产用于体位监测的低成本床垫传感器（床垫传感器）。该床垫传感器的一个应用，适用于研究和临床 设置，是否监测和记录受试者？的身体位置，运动和睡眠研究过程中的过渡。通过添加一些电子器件，床垫传感器将在临床环境中有用，以在患者没有进行压力分布的显著变化并且有形成压力性溃疡的风险时提醒护理人员。与其他防跌倒系统相反，在患者福尔斯跌倒或离开床之前，可以使用具有床垫传感器的适当电子设备，以在患者处于床的边缘并且有跌倒或离开的风险时通知护理人员。 拟定商业应用： 该设备可以在睡眠研究期间使用，以识别患者的运动。 该设备可用于医院和长期护理机构，以减少压疮形成或患者离开或即将离开病床时的通知。

DESCRIPTION (provided by applicant): This program will develop a low cost sensor mat to monitor an individual?s body position while sleeping. Presently, the only systems that monitor body position in a bed without any wires or sensors attached to the person are designed for high-resolution analysis of the pressure and change in pressure distribution therefore using 200+ sensors and require expensive and complicated systems. A low cost system that can identify the approximate body position, or more importantly changes in body position would be a valuable tool in both research and clinical application. The goal of this proposal is to test and identify the minimum number of sensors that are required to identify body position changes and produce a Low Cost Mattress Sensor for Body Position Monitoring (Mattress Sensor). One application for this Mattress Sensor, which is applicable in both the research and the clinical settings, is the monitoring and recording of a subject?s body position, movement and transitions during sleep studies. With the addition of some electronics, the Mattress Sensor will be useful in the clinical setting to alert a caregiver when a patient has not performed a significant change in the pressure distribution and is at risk of forming a pressure ulcer. As opposed to other fall prevention systems, appropriate electronics with the Mattress Sensor can be used before the patient falls or leaves the bed, to notify a caregiver when a patient is at the edge of the bed and at risk of falling or getting out. PROPOSED COMMERCIAL APPLICATION: The device can be used during sleep studies to identify patient movements. The device can be used in hospital and long-term care facilities to reduce pressure ulcer formation or notification when a patient leaves or is about to leave the bed.
