Non-contact Optical Temperature Sensor for Neonatal Monitoring.

描述（由申请人提供）：总结通过将婴儿保持在恒温箱/加热器提供的可控温度环境中，新生儿存活率大大提高。为了准确地控制体温，有必要对婴儿进行一致、可靠的体温测量。这是目前完成使用的温度传感器（热敏电阻）是通过粘合剂的方式贴在身体。这种方法的缺点是是单点测量，粘接剂会损害婴儿娇嫩的皮肤。此外，传感器容易移位，导致反馈温度控制问题。基于这些原因，我们建议开发和测试一种基于具有温度敏感分子的凝胶的非接触式温度传感方案。所提出的分子是荧光的，其发光随温度的变化而变化。通过这种方法，凝胶可以使用LED远端激发，并通过便宜的数码相机成像。先进传感器技术中心和通用电气医疗保健提出了一个R21项目，该项目将开发和测试用于非接触式温度传感的传感凝胶和仪器。该系统将在包裹着猪皮的装满水的娃娃上进行测试，以模仿新生儿。我们希望在两年的项目结束时，该系统可以进行动物和人体试验。

DESCRIPTION (provided by applicant): Summary Neonatal survival is greatly improved by keeping the baby in a controlled temperature environment provided by an incubator/warmer. In order to control body temperature accurately, consistent and reliable temperature measurement of the baby is necessary. This is currently accomplished using a temperature sensor (thermistor) that is affixed to the body by means of an adhesive. This approach has the disadvantage of being a single point measurement and the adhesive can distress the delicate skin of the infant. Furthermore, the sensor is prone to dislodgement, leading to problems with feedback temperature control. For these reasons, we propose to develop and test a non-contact temperature sensing scheme based on a gel that has a temperature sensitive molecule in it. The proposed molecules are fluorescent and their luminescence varies as a function of temperature. With this approach, the gel can be distally excited using an LED and imaged via an inexpensive digital camera. The Center for Advanced Sensor Technology and General Electric Healthcare propose an R21 project that will develop and test the sensing gel and instrumentation for non- contact temperature sensing. The system will be tested on water filled dolls wrapped in pigskin to mimic a neonate. We expect the system to be ready for animal and human trials at the end of the two year project. PUBLIC HEALTH RELEVANCE: A non-contact temperature sensor is proposed for use with infants in incubators/ baby warmers. This sensor will allow for monitoring body temperature of neonates without the current problems of adhesive-based wired sensors that are attached to the delicate skin of the newborn.
