热电酶传感器是一种新颖的测量血糖的量热型方法,传惑器由一个薄膜热电偶构成,热电偶安装在一个绝缘骨架上,缠绕在3毫米直径的导管端头。通过热电偶污化热电节点上的酶葡萄糖氧化物的失活,使传感器对葡萄糖酶感。当溶液中放入葡萄糖时,由于酶反应而产生的热焓的变化,酶电变热。在热电偶上的活化点相参考点间产生温度差,进而产生一个与葡萄糖成比例的电压信号。在离体血中试验时,传感器感应的是血浆中的葡萄糖浓
Thermo-enzyme sensor is a novel calorimetric method for measuring blood glucose. The sensor consists of a thin film thermocouple mounted on an insulative frame wrapped around a 3 mm diameter catheter tip. Through thermocouple contamination of the thermoelectric node on the deactivation of the enzyme glucose oxide, so that the sensor of glucose enzyme sense. When glucose is added to the solution, the enzyme heats up as the enthalpy changes due to the enzyme reaction. The temperature difference between the reference points of the activation point on the thermocouple produces a voltage signal proportional to glucose. In ex vivo blood tests, the sensor senses glucose concentration in the plasma
