【摘要】 靜脈輸液是我國目前臨床治療中最主要的一種輸液方式,在實踐工作中,醫(yī)護人員一般是靠經(jīng)驗和觀察通過轉(zhuǎn)動輸液器上的滑輪對滴速進行手動調(diào)節(jié)的,這種方法經(jīng)常會出現(xiàn)一些異常情況：一、臨床經(jīng)驗不是很豐富的醫(yī)護人員對滴速的把握就不會很準確,容易造成輸液速度過快導致患者出現(xiàn)不適或速度過慢而影響治療效果；二、若輸液時間較長,容易導致醫(yī)護人員和患者的疏忽,增加醫(yī)療事故隱患。三、需要隨時監(jiān)控輸液情況,加大了醫(yī)護人員的工作任務。因此提高輸液系統(tǒng)的智能化和自動化以及降低輸液過程中的隱患勢在必行。本文設計了一種以PC機為上位機,以MSP430F149單片機為眾下位機的RS485總線智能輸液監(jiān)控系統(tǒng)。上位機采用Visual C++編程語言,創(chuàng)建了一個可視化的人機界面,通過該界面可以監(jiān)視剩余液量、目標滴速、實際滴速、報警等信息。下位機設計了具有RS485總線轉(zhuǎn)換接口、滴速設置鍵盤、LCD數(shù)據(jù)顯示、液滴紅外檢測、步進電機控制、報警等功能的輸液終端監(jiān)控系統(tǒng)。該智能醫(yī)療輸液系統(tǒng)可以對多床位的輸液情況進行遠程監(jiān)控,能針對不同的病人設定不同的滴速,輸液出現(xiàn)異常情況時會產(chǎn)生報警,液體輸完時可自動切換至另一瓶。本智能醫(yī)療輸液系統(tǒng)可以提高醫(yī)院的服務水平和服務質(zhì)量,減少輸液過程中出現(xiàn)的醫(yī)療事故,增強醫(yī)院市場競爭力。
【Abstract】 Vein infusion is the most significant way of clinical treatments in China. Through observation and experience, nurses usually turn the pulley by hand to adjust the speed of infusion in practice. But this method often leads to a variety of abnormal situations:Firstly, for some nurses of poor clinical experience they could not control the drip rate very accurately, that is to say, infusion speed is either too fast to make patients discomfort or too slow to influence the treatment effects; Secondly, the longer infusion time could easily result in the negligence of patients and increase medical risks; Thirdly, the need to keep monitoring the situation of infusion adds the workloads of medical staff. Thereby, it is imperative to enhance the intelligence and automation of infusion system and decrease the risks in the transfusion process.This paper designed an intelligent infusion monitoring system which takes advantage of RS485 bus network and personal computer as the upper computer and MSP430F149 microcontroller as the terminal. In the upper computer, it utilized VC++ programming language to devise a visual user interface through which the nurse could monitor the information of remaining liquid volume, target speed, transfusion speed, alarm and so on. In the terminal, this thesis designed the transfusion-surveillance-control system, which includes RS485 bus transfer interface, dip rate setting keyboard, LCD data display, infrared test of liquid drop, stepper motor control alarm and so on.This intelligent medical infusion system can remote monitor the situations of multi-bed infusion, set different drip rates for various patients, produce an alarm when the unusual infusion circumstance happens, and automatically switch to another bottle when the liquid uses up. This proposed intelligent medical infusion system can elevate the hospital’s service level and quality of service, cut down on occurrences of medical malpractice during infusion, and enhance the market competitiveness of the hospital.
