一种新型恒温输液输血装置设计

针对市面上现有的恒温输液装置或依赖进口,或体积庞大,在很多小型医院不适用等特点,设计出了一款轻巧便宜的新型恒温输液输血装置。经实验测试,实现了对液体包括血液的加热恒温等一系列功能。装置的主控芯片选用STM32微控制器,加温器选用220V,68W的硅橡胶加热片,温度检测器选用DS18B20。利用PID算法加快了温度控制系统的响应速度,实现了恒温控制功能。同时,有效地抑制了温度抖动,使装置在运行时更加稳定、可靠。另外,还通过显示屏、语音合成模块、红外遥控开关等人机交互系统,实现了装置的智能化,使之提供更加人性化的服务。

A New Type of Constant Temperature Infusion and Transfusion Device

In view of the existing constant temperature infusion device on the market or relying on import, or large size, it is not applicable in many small hospitals, and a new type of constant temperature infusion blood transfusion device was designed. Through experimental tests, a series of functions such as heating and heating of liquids including blood have was realized. The main control chip of the device is STM32 microcontroller, the heater is 220V, 68W silicon rubber heating plate, and the temperature detector is DS18B20. The PID algorithm accelerates the response speed of the temperature control system and realizes the constant temperature control function. At the same time, the temperature jitter is effectively suppressed, which makes the device more stable and reliable during operation. In addition, through the human-computer interaction system such as the display screen, speech synthesis module, and infrared remote-control switch, the intelligentization of the device is realized, so that a more humanized service is provided.
