【摘要】 目前,市面上的电动气压止血带设备体积较大,不仅不利于操作,还挤占了手术室狭小的空间。设计了一种以STM32为控制核心的双通道气压止血带,气压传感器的输出信号经过信号处理后送给STM32的AD端口,结合气压设定值和阈值,控制相应的气泵充气或电磁阀充气,采用DGUS屏实现人机界面。结果表明,所设计的双通道气压止血带能够准确控制止血带的充气压力与放气时间,能实现实时监控压力、自动气压补偿、定时报警等功能。更多还原

【Abstract】 A double channel pneumatic tourniquet with STM32 as the control core is designed in this paper.The output signal of the pressure sensor is sent to the AD port of STM32 after signal processing,and the air pressure setting value and threshold are combined to control the corresponding air pump inflating or electric magnetic valve deflating.The manmachine interface is realized by the DGUS screen.更多还原
