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.

描述（由申请人提供）：摘要新生儿生存可以通过将婴儿保存在孵化器/温暖器提供的受控温度环境中，从而大大提高。为了准确控制体温，必须对婴儿进行一致且可靠的温度测量。目前，使用温度传感器（Thermistor）来完成，该温度传感器（热敏电阻）通过粘合剂固定在体内。这种方法具有单点测量的缺点，并且粘合剂会使婴儿的精致皮肤感到困扰。此外，传感器容易脱位，导致反馈温度控制问题。由于这些原因，我们建议基于具有温度敏感分子的凝胶开发和测试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。使用这种方法，可以使用LED远端激发凝胶，并通过廉价的数码相机成像。高级传感器技术和通用电气医疗保健中心提出了一个R21项目，该项目将开发和测试传感凝胶和仪器，以进行非接触温度传感。该系统将在包裹在猪皮上的水娃娃上进行测试，以模仿新生儿。我们预计该系统将在两年项目结束时为动物和人类试验做好准备。 公共卫生相关性：提出了一种非接触式温度传感器，供婴儿在孵化器/婴儿加热器中与婴儿一起使用。该传感器将允许监测新生儿的体温，而没有附着在新生儿脆弱皮肤上的基于粘合的有线传感器的问题。
