澳大利亚的电子工程师Stan Clark发明了一种测量血液中血糖含量的简单仪器。这种仪器操作简便,可由糖尿病患者在家中自己测定血糖量,测试结果可在两分钟内获得。仪器使用交流电或电池进行操作。在测试器内,有一组光电发射检测装置。把一滴血样涂在含有药膜的反应片上,利用反应片上血色变化的深浅,对反射光进行光电处理, Stan Clark, an electronic engineer in Australia, invented a simple instrument for measuring blood sugar levels in the blood. The easy-to-use instrument allows blood glucose levels to be measured in the home by diabetic patients and the test results are available within two minutes. The instrument operates on AC or battery. Inside the tester there is a set of photoemission detection devices. A drop of blood sample is coated on the reaction film containing the drug film, the depth of the change of the color on the reaction chip is used, and the reflected light is photoelectrically treated,
