基于STM32的智能输液装置设计

Design of intelligent infusion device based on STM32

在中国北方较为寒冷的偏远地区,条件简陋,冬季温度过低,病人在输液治疗时由于待输药液温度偏低,输液过程中病人会感到输液部位有麻木、疼痛感,长时间输液会使病人感到寒冷、甚至发抖,有的药物对输液温度也有要求,本文以STM 32嵌入式为控制核心,利用PID算法完成了输液温度控制,并且加入称重、心率测量、蓝牙等模块等智能化扩展,并完成了药液监控、心率监测、时时传输病人当前输液状况的功能。系统通过测试在实用性、安全性及稳定性等方面性能较强,可以减轻部分护理工作,适合推广于住院环境和护理方面欠缺的小城镇医院和卫生室。

In the cold,remote areas of northern China,the conditions are simple and the temperature in winter is too low.During the infusion treatment,the patient will feel numbness and pain in the infusion process due to the lowtemperature of the infusion solution.Long time infusion will make the patient feel cold and tremble.Some drugs also require the infusion temperature.After practice,the STM32 embedded system is used as the control core and PID algorithm to complete the infusion temperature control,and the weighing,heart rate measurement,Bluetooth and other modules are added for intelligent expansion,and the functions of liquid medicine monitoring,heart rate monitoring and real-time transmission of patients’current infusion status are completed.Through the test,the system has strong performance in practicability,safety and stability,and can reduce part of the nursing tasks.It is suitable to be popularized in hospitals and clinics in small towns.
