基于单片机的输液监控系统设计

南京信息工程大学电子信息工程专业,南京 210044

摘要:在医院输液的时候,医护人员和病人经常被一个问题所困扰:在给病人进行输液治疗的时候,经常因为病人身体虚弱、昏睡,而此时医护人员又正在别的地方工作,导致没注意到。当输液结束以后,如果没有处理及时的话,因为输液管空了,病人静脉血会发生倒流的情况,使病人有发生生命危险的可能。但是若处理过早,又会造成药液浪费,减轻药效,影响治疗。本文设计的输液监控系统,利用药液和空气对光的折射率的不同,使同一处光源的光在有、无药液时,发生不同角度的折射,按光接收元件收到的光的强弱输出高电平或低电平,从而确定单片机是否驱动蜂鸣器报警和数码管显示病人座位号码,避免因工作繁忙、病人过多引起错误。 关键字:单片机;输液;监控;报警

Abstract

Infusion in the hospital, medical staff and patients are often beset with a question: when the transfusion treatment to patients, often because the patient's body weakness, lethargy, and the medical staff are working somewhere else and then lead to not to notice. When after the infusion, if not timely handling, because the iv empty, patients with venous blood backflow of happens, the patient has a possibility of a life.But if handled too early, it will cause the liquid waste, reduce the effect, influence the treatment.Infusion monitoring system designed in this paper, the use of different light refractive index of liquid and air, make the light of the light source with liquid in the same place, different Angle of refraction, according to the light receiving element receives the strength of the light output high level or low level, so as to determine whether MCU drive buzzer alarm and digital tube display the patient seat number, and avoid the errors caused by job is busy, too many patients. Key words: single chip microcomputer; infusion; monitoring; alarm
