摘要
随着计算机科学技术、通信技术的快速发展,与人类健康息息相关的医学领域也不可避免地被赋予了数字化理念。社会的不断发展,人们对个体生命价值认知的不断提升,越来越多用户病人希望利用高科技手段保障生命,一种设计合理、技术先进、经济、实用、可靠的医用超声智能雾化器将会受到社会的欢迎。
经调查,在“非典”过后的今天,随着超声技术的发展,超声技术在雾化治疗方面被广泛应用,超声雾化器已是临床不可缺少的医疗仪器之一。它具有构造简单、价格适中、操作方便、应用范围广泛、治疗效果可靠、方便、无痛苦、药物副作用小、使用成本低、安全可靠、维修方便等优点,故在临床治疗中得到广泛的应用,是一个不可替代的辅助治疗手段。超声波雾化器不仅可在医院作为对患有呼吸道疾病病人的治疗给药器具,更可作为家庭空气加湿、清毒、预防疾病及室内盆景造型等多种用途。
本文是在智能雾化器系统项目开发的基础上总结完成的,作者的主要研究开发工作如下:
(1)在本次智能雾化器的开发试验中,作者以单片机为核心,实现对内部功能的控制,并分别对影响设备输出量的主要因素的进行检测。其中包括设备雾化量、风机转速和对设备工作温度的检测,并配有液晶屏显示,数据存储部分,将治疗参数和设备状态显示出来,实现了人机交互功能,并将临时的数据储存储在存储器X5045中。
(2)在嵌入式开发的基础上,作者将两种高频振荡器进行了比较和分析,实现了对最优方案的设计,并用单片机对其性能进行了控制实现,从而使雾化器在整体的性能上优于传统的设计开发。
(3)根据实际需求,设计并实现了基于蓝牙技术的无线传输的通信链路。可将采集到的参数通过蓝牙无线协议上传至上位机,同时,可接收上位机下传的运行控制参数,增强设备的网络治疗功能,也弥补现有医疗监护系统的不足。
(4)最后作者对整个智能雾化器系统进行了调试和结果分析,总结了系统的不足之处,并且提出了系统有待进一步改进和完善的问题。
With the rapid development of the technology of computer science and communication, the logos of digital are inevitably bestowed upon the medical field which closely interrelated to the human. The life value acknowledge of people continuously promotes with the development of society, more and more patients hope for life-support by using high technolgy. So a rational designed medical ultrasonic atomizer with advanced technology will be welcome, which with economical, pragmatic and reliable characteristics.
Along with the development of ultrasound technology, ultrasound technology has been widely used in aerosol therapy and clinical ultrasound nebulizer is one of the indispensable medical equipment nowadays after "SARS". It has been widely applied in clinical treatment and has become an irreplaceable means of treatment on account of its' many merits, such as simple structure, modest price, easily operate, widely used, perfect efficacy, pain-free, tiny side effect, low costs, safely, easily maintain and so on. Ultrasonic nebulizer can be applied as not only the dose in the treatment of patients suffering from respiratory, but also air humidified devices, sterilize, disease prevention, indoor potted plant modeling and other kinds of roles.
This paper implements on the basis of the project of intelligent atomizer system.
Here the main works are:
(1) Embedded microprocessor part of the core function is the realization of internal control, and detects the mainly factors which influents the exports of the equipment, including equipment spray volume, fan speed, temperature detection equipment, equipped with LCD screen and data storage to display the treatment parameter and equipment status. It realizes human-computer interaction and provisional data will be stored in memory on which X5045.
(2) In the development of the intelligent atomizer, the optimal decision is designed by analyzing and comparing the two high-frequency oscillators, and its' performance is controlled by a microprocessor controller. So the overall performance is superior to the conventional design.
(3) Bluetooth wireless transmission technology based on the communication link, the parameters can be collected through Bluetooth wireless transmission up agreement. Meanwhile, the PC will be able to receive control parameters to enhance the treatment of functional network equipment and fill the existing deficiency of the traditional health care system.
(4) Finally, we reviewed the development process of the whole system, summarized the systematic weak point, and put forward the advice on improving and perfecting the system.
