介绍了一种基于DSP芯片TMS320F2407的无创性食管静脉曲张测压系统。它具有高精度的静脉曲张压力检测能力和高性能的数字信号采集与处理能力,并通过RS232标准串行总线实现DSP与PC机之间的高速数据通讯。经临床应用表明,该系统能准确测定食管曲张静脉内压,在临床评估食管曲张静脉出血危险程度方面具有良好的应用价值。
A noninvasive esophageal varicose vein pressure measurement system based on DSP chip TMS320F2407 is introduced. It has high-precision varicose pressure detection capabilities and high-performance digital signal acquisition and processing capabilities, and through the RS232 standard serial bus to achieve high-speed data communications between DSP and PC. The clinical application shows that the system can accurately measure the intra-variceal pressure and has a good application value in the clinical evaluation of the risk of esophageal variceal bleeding.
