一、前言当前中医脉象的研究主要是建立各种脉象典型图谱,研究各种脉象形成的机理并作客观的定量分析。这就要求有性能稳定可靠,参数统一,并符合中医脉诊传统特点的仪器设备。所以脉象仪的研制需满足如下要求:重复性好,长时间描记的稳定性好,取法压力值连续可调并能方便地读取和标记,仪器的增益状态可以标记,有足够的频响、灵敏度和动态范围以及价廉便携等。 MX-3型脉象仪在主要性能指标满足中医脉象研究需要的前提下进行了简化设计。经两年多的临床试用,证明这一设计方法是
I. Introduction At present, the research of TCM pulse is mainly to establish the typical pulse patterns, study the mechanism of various pulse formation and make objective quantitative analysis. This requires stable and reliable performance, uniform parameters, and consistent with traditional Chinese medicine pulse diagnostic equipment. Therefore, the development of pulsers must meet the following requirements: good repeatability, good stability for long time tracing, continuously adjustable pressure values and easy reading and marking, the gain state of the instrument can be marked, there is enough frequency response, Sensitivity and dynamic range as well as cheap and portable. MX-3-type pulse instrument in the main performance indicators to meet the needs of Chinese pulse research on the premise of a simplified design. After more than two years of clinical trial to prove that this design method is
