基于单片机的智能输液系统的设计(任务书,开题报告,外文翻译,论文15000字)
摘要
静脉输液在当今的临床治疗中是最常用的治疗手段之一，既可以给病人输注药物又可以补充体液和营养。在输液过程中输液流速是值得重点关注的一个指标，流速需要根据病人体质、药物特性等因素来确定，而现在医院的输液器不能满足这个需求，流速凭经验设置且不稳定，发生异常情况不容易发现，导致医疗事故发生，造成医患关系紧张，急需一款智能输液系统解决此问题。
本文设计了一套以STC89C52单片机为核心的智能输液系统。该系统由STC89C52单片机电路、按键电路、红外对管模块电路、液晶LCD1602电路、ULN2003步进电机驱动电路和电源电路组成。可以实现对输液过程中滴速的实时监测和实施控制，使滴速保持在设置的标准值，在输液结束或出现异常时可以报警和停止输液。测试结果表明本系统具有精准的检测和控制能力，可扩展性高，大大提高了病人输液的安全性，也减轻了医护人员的工作量，达到了预期的设计指标。

Abstract
Intravenous infusion is one of the most commonly used treatment methods in today's clinical treatment. It can not only infuse drugs to patients, but also supplement body fluids and nutrition. In the process of infusion, the infusion velocity is an important indicator, which needs to be determined according to the patient's physique, drug characteristics and other factors. Now the infusion device in the hospital can not meet this demand. The flow velocity is set by experience and unstable, and the abnormal situation is not easy to find. Medical accidents often occur, which makes the doctor-patient relationship tense. An intelligent infusion system is urgently needed. To solve this problem.
This paper designs an intelligent infusion system based on STC89C52 single chip computer. The system consists of STC89C52 single chip computer circuit, key circuit, infrared tube module circuit, LCD 1602 circuit, ULN2003 stepper motor drive circuit and power circuit. It can realize the real-time monitoring and control of the drip speed in the process of infusion, keep the drip speed at the set standard value, and alarm and stop infusion when the infusion is over or abnormal. The system has the ability of accurate detection and control, high expansibility, greatly improves the safety of patients'infusion, also reduces the workload of medical staff, and achieves the desired purpose.
Key Words: intravenous infusion; microcontroller; drip speed detection; drip speed control
