Exploration of Socket Cooling Using Novel Passive Heat Spreader Technology

描述（由申请人提供）： 这个试点项目是为了探索使用插座的辅助冷却来提高插座舒适度的问题。Celsia NanoSpreader Vapor Cooler技术是一种新型的被动平面冷却技术，专为冷却微处理器而开发，我们相信它可以应用于插座冷却问题。 假体废弃的一个主要原因是舒适性问题，其中之一是它们经常太热-特别是在肩关节离断或前躯水平，其中承窝覆盖了剩余躯干的大部分。此外，假肢接受腔内部的不同强度的出汗会产生表面EMG电极检测到的信号的变化。主动冷却可以解决这个问题。该项目的目标是提供一种重量轻、成本低的被动能源方法，将多余的热量从皮肤表面转移到假体外部。 Celsia是一种新型的平面冷却技术，用于冷却微处理器，我们认为可以应用于插座冷却问题。这个试点项目是为了探讨使用辅助冷却的插座，以提高插座的舒适性的问题。Celsia技术之所以吸引人，是因为它是一种完全被动的设备-不需要外部电源来驱动用于分散废热的热泵作用。 在第一年，我们建议制作旁路插座，使完整的个人可以穿类似的人穿肩关节离断截肢的插座。这些插座要么是实心的（没有NanoSpreader），要么有简单的孔切口用于空气冷却，要么内置NanoSpreader。使用这些大表面积的接受腔，我们将解决与使用纳米扩张器相关的扭结以及将它们集成到假肢接受腔中所涉及的任何问题。在第二年，我们将招募下肢截肢者，让他们测试为下肢制作的类似插座。 我们将让受试者戴着这些插座在水平跑步机上行走，并以三种不同的速度行走，同时监测插座内的温度并测量O2消耗量。在每个受试者疗程结束时，应提供无插座、实心插座、带切口的插座、带NanoSpreader的插座的4个温度数据集。 公共卫生相关性： 这个试点项目是为了探索使用插座的辅助冷却来提高插座舒适度的问题。Celsia是一种新型的被动式平面冷却技术，我们相信它可以应用于解决插座冷却问题。 假体废弃的一个主要原因是舒适性问题，其中之一是它们经常太热-特别是在肩关节离断或前躯水平，其中承窝覆盖了剩余躯干的大部分。此外，假肢接受腔内部的不同强度的出汗会产生表面EMG电极检测到的信号的变化。主动冷却可以解决这个问题。这个项目的目标是提供一个轻量级的， 低成本的被动能源方法，将多余的热量从皮肤表面转移到假体外部。

DESCRIPTION (provided by applicant): This Pilot project is to explore the issue of using assisted cooling of the socket to improve socket comfort. Celsia NanoSpreader Vapor Cooler technology is a novel passive planar cooling technology developed for cooling microprocessors that we believe can be applied to the problem of socket cooling. A leading cause of prosthesis abandonment are comfort issues one of which is they are frequently too hot - particularly at Shoulder disarticulation or forequarter level where the socket covers a large portion of the remaining torso. Additionally, the variable intensity sweating inside of the prosthesis socket produces changes in the signals that surface EMG electrodes detect. Active cooling may offer a solution to this problem. The goal of this project is to provide a lightweight, low cost, passive energy method to move the excess heat from the surface of the skin to the outside of the prosthesis. Celsia is a novel planar cooling technology developed for cooling microprocessors that we think can be applied to the problem of socket cooling. This Pilot project is to explore the issue of using assisted cooling of the sockt to improve socket comfort. The Celsia technology is attractive because it is a completely passive device - no external electrical power is necessary to drive the thermal pumping action which is used to disperse waste heat. In the first year we are proposing to fabricate bypass sockets so that intact individuals may wear a socket similar to that worn by person with shoulder disarticulation amputations. These sockets will be are either solid (no NanoSpreader), have simple hole cutouts for air cooling, or have the NanoSpreader built in. Using these large surface area sockets we will work out the kinks associated with the use of the Nanospreader and any issues involved with integrating them into a prosthetic socket. In the second year we will recruit persons with lower-limb amputations and have them test similar sockets fabricated for the lower-limb. We will have the subjects walk on a level treadmill while wearing these sockets and walking at three different speeds while monitoring the temperature inside the socket and measuring O2 consumption. At the end of each subjects session there should be 4 temperature data sets for No socket, solid socket, socket with cutouts, socket with NanoSpreader.
