目的:设计一种新型身高体重电子测量仪,提高检查效率。方法:该仪器基于超声波测距的原理测量身高,采用精密平衡梁式压力传感器测量体质量,由体重秤与身高测量仪2个部分组成。体重秤包括体重秤基体、称重踏板、容置腔(内有驱动电动机、垫巾槽、垫巾辊、回收辊)。身高测量仪包括主体、连接体、多功能拓展台、超声波测量装置、控制按钮、数码语音播报显示屏。结果:新型身高体重电子测量仪缩短了检查者的检查时间,避免了检查者之间发生交叉感染的隐患,减轻了医务工作者的工作量。结论:该仪器设计合理、人性化,测量方便、准确,可推广使用。

Objective To design an electronic measuring instrument for height and weight. Methods The instrument detected the height with the principle of ultrasonic ranging and the weight with precision-balance-beam-like pressure sensor, which was composed of a weighing scale and a height measuring apparatus. The weighing scale consisted of a base, a weighing pedal and a holding chamber containing a drive motor, a towel cavity, a towel roller and a recovery roller. The height measuring apparatus was made up of a body, a connector, a multi-function expansion platform, an ultrasound measuring instrument, control knobs and a digital speech broadcast display. Results The measuring instrument shortened the examination time consumed, eliminated the hidden risks for cross infection and decreased the work load of medical staffs.Conclusion The instrument behaves well in design, convenience and accuracy, and thus is worthy promoting practically.
