脉诊仪机构的开发与计算机辅助设计 摘要 脉诊在中医占很重要的地位，通过脉诊可以了解患者脏腑气血的盛衰，可以探测病因、病位、预测疗效等。临床脉诊时对某一脉象的认识是以医生手指的感觉并结合该医生对脉象理论的理解来加以鉴别与区分。由于脉象理论本身较笼统，具体的判别标准又很模糊，其中还掺杂了医生的判别经验及手指感觉等很多主观因素，因此中医脉象在教学中困难较大，临床脉诊时分歧较多。为了让中医走向世界，中医脉诊客观化、现代化势在必行。 随着机械及电子技术的发展，国内外在研制中医脉象仪方面已经有了很大的进展。但是这些脉象仪只是把当时的脉象信息打印出来，而没有用数据的形式进行存储，如果以后想要再处理这个脉象信息就办不到了，因此我们利用计算机对脉象信息在实时显示的同时还对其进行存储，为进一步分析脉象信息及研究脉象信息与疾病的关系做了准备。 本系统中单片机系统主要完成信号采集、数据通信；微机完成数据接收、存入数据库、数据处理、显示等功能。 本文详细介绍了脉象检测仪的机构设计。包括CAD零件设计，UG三维造型。并且介绍了必要的伺服电机控制电路等内容。 关键词　脉象；单片机系统；UG三维造型；伺服电机 Diagnosis by Feeling the Pulse Meter Organization Development and Computer-Aided Design Abstract It is well known that pulse-taking is very important in department of traditional Chinese medicine, Herbalist doctors think that they can gain sufferer’s pathogeny and　symptom by pulse tracings. When doctor takes in clinic pulse-taking, cognition to pulse tracings combines experience of finger and comprehend to pulse tracings. But the pulse tracings are difficult to be commanded, and the standard of distinguish is fuzzy, so there are much difficulties and divergence in teaching and clinic. Pulse-taking must be objective for tending towards the world.　 Now, along with the development of machine and electronics, there are　progresses in manufacturing electropulsogragh. But the electropulsogragh can only give the wave of sufferer’s pulse information, it cannot save them, so we cannot process the information. In the thesis, this problem is solved.　 In this system, the microchip system focuses on sampling signals and data　communication, and the microcomputer completes data acceptance, storage to　database, data processing, display and other functions. The paper expounds on the design of Pulse Data Checking System.It consists of the design of CAD, and UG three-D modeling and expounds some necessary electrical control.
