项目摘要

DESCRIPTION (provided by applicant): The results of the Phase I effort, during the course of which the physiological signals of eight mice were determined and correlated with established "golden standard" techniques, have demonstrated the feasibility of monitoring and identifying clearly distinguishable physiological signals by measuring the mouse's chest movements with a saddle-type sensor. More importantly, the results clearly established that this sensor can answer the need for the long-term and continuous monitoring of mobile mice, particularly those animals whose state of health is so precarious as a result of genetic intervention and age that invasive monitoring means are not an option. As part of the Phase II effort the system will be miniaturized so that the entire sensing assembly can be moved onto the mouse and a miniature wireless transmission system will be integrated into the sensor system. The real-time signal processing algorithms will be optimized and a computer-based graphical user interface (GUI) completed. In order to validate the performance of the sensing system, two studies will be performed at the University of Virginia on mouse populations whose fragile state of health does not permit invasive monitoring. One study will involve mice with inducible myotonic dystrophy, while the other will study asthmatic mice. An alliance has been formed with a well-known manufacturer of physiological monitoring equipment to commercialize the product. The need for the long-term monitoring of cardiopulmonary rhythms in mice is growing along with an increasing population of mice strains that are being used to test drug responses, genetic engineering attempts, and other factors that can affect these biological rhythms. This sensor technology can answer the need for the long-term and continuous monitoring of mobile mice, particularly those animals whose state of health is precarious as a result of genetic intervention and age that invasive monitoring means are not an option.

描述（由申请人提供）：第一阶段努力的结果，在此过程中，确定了八只小鼠的生理信号并与已建立的“黄金标准”技术相关，证明了通过通过SADDLE-SADDLE-PE SENSOR测量小鼠的胸部运动来监测和识别可明显区分生理信号的可行性。更重要的是，结果清楚地表明，该传感器可以回答对移动小鼠的长期和持续监测的需求，尤其是那些由于遗传干预和年龄而变得如此不稳定的动物，以至于侵入性监测手段不是一种选择。作为II期努力的一部分，该系统将被小型化，以便可以将整个传感组件移至鼠标上，并将微型无线传输系统集成到传感器系统中。实时信号处理算法将进行优化，并完成基于计算机的图形用户界面（GUI）。为了验证传感系统的性能，将在弗吉尼亚大学对脆弱的健康状况不允许侵入性监测的小鼠种群进行两项研究。一项研究将涉及患有诱导肌营养不良的小鼠，而另一个将研究哮喘小鼠。已经与著名的生理监测设备制造商建立了联盟，以使产品商业化。长期监测小鼠心肺节律的需求正在增长，随着小鼠菌株的越来越多，用于测试药物反应，基因工程尝试以及其他可能影响这些生物节奏的因素。该传感器技术可以回答对移动小鼠的长期和持续监测的需求，尤其是那些由于遗传干预和年龄而危害健康状况的动物，因此侵入性监测手段不是一种选择。
