【摘要】：听诊器作为医生最常使用的医疗仪器,在心脑血管疾病、呼吸系统疾病诊断中意义重大。而传统声学听诊器无法存储回放、不能无线传输数据、抗环境干扰能力差等缺点,限制了听诊在远程医疗、移动医疗、医学教学等方面的进一步使用。电子技术的发展使电子听诊器应运而生,并使远程听诊成为可能。而目前国内外电子听诊器存在产品少、价格贵、功能单一等不足,阻碍了电子听诊器的广泛使用。鉴于此,本论文研究提出了对便携式电子心肺音听诊器进行研制。本论文研究首先明确了电子听诊器的功能需求、技术指标及设计要求,确定了包括拾音传感器、主控模块、音频编解码模块、音频存储模块、显示模块和蓝牙模块等在内的技术方案,然后基于两种不同的拾音传感器研制了两款便携式电子听诊器产品样机。第一款基于压电传感器的样机已通过包括GB9706电气安全、YY0505电磁兼容在内的医疗器械产品注册检验,获得注册检验报告,进入注册证申请阶段。第二款样机采用听诊头和电容式传声器结合的拾音传感器,创新性的引入了悬浮式可调振动膜,并可针对不同频段心肺音进行听诊模式选择。第二款样机在第一款基础上进行了产品优化升级,实现了样机小型化,增加了产品的便携性和实用性。其次结合基于PC的上位机软件实现对便携式电子心肺音听诊器的功能扩展。上位机软件以C#为编程语言,SQL Server为后台数据库,在PC端实现了对病人个人信息和心肺音信息的管理、心肺音数据接收存储、波形绘制及播放、辅助诊断等功能。本文研制的便携式电子心肺音听诊器功能完善、成本低、便携性高,适用于医院听诊、医学教学等多种场合,并有利于听诊在远程医疗、移动医疗、互联网健康管理等多方面的应用。
[Abstract]:Stethoscope, as the most commonly used medical instrument by doctors, is of great significance in the diagnosis of cardiovascular and respiratory diseases. Traditional acoustic stethoscopes can not store playback, can not transmit data wireless, and poor ability to resist environmental interference, which limits the further use of auscultation in telemedicine, mobile medicine, medical teaching and so on. The development of electronic technology makes electronic stethoscope come into being and make remote auscultation possible. At present, there are few products, expensive price and single function of electronic stethoscope at home and abroad, which hinder the wide use of electronic stethoscope. In view of this, a portable electronic cardiopulmonary stethoscope is proposed in this paper. In this paper, the functional requirements, technical specifications and design requirements of the electronic stethoscope are defined, including the pickup sensor, the main control module, the audio codec module, the audio storage module. The display module and Bluetooth module are used to design two portable electronic stethoscopes based on two different pickup sensors. The prototype based on piezoelectric sensor has passed the registration inspection of medical device products including GB9706 electric safety device YY0505 EMC and obtained the registration inspection report and entered the registration application stage. The second prototype adopts the pickup sensor which combines auscultation head and capacitive microphone, and innovatively introduces suspension adjustable vibration film, and can select auscultation mode for different frequency range of cardiopulmonary sound. The second prototype is optimized and upgraded on the basis of the first model, realizing the miniaturization of the prototype and increasing the portability and practicability of the product. Secondly, the function of portable electronic cardiopulmonary stethoscope is extended by PC-based software. The upper computer software takes C # as the programming language SQL Server as the backstage database, realizes the management of the patient's personal information and the cardiopulmonary sound information at the PC end, receives and stores the cardiopulmonary sound data, draws and plays the waveform, assists the diagnosis and so on. The portable electronic cardiopulmonary sound stethoscope developed in this paper has the advantages of perfect function, low cost and high portability. It is suitable for hospital auscultation, medical teaching and other occasions, and is beneficial to auscultation in telemedicine and mobile medicine. Internet health management and other applications.
