中文摘要：

针对有创血压测量设备研发阶段、校准测试或在教学实验中难以采用人体或动物来做试验的缺点，提出一种新型有创血压模拟器设计方法。该模拟器通过微控制器产生正弦波和各种人体血压波形，输送到扬声器产生振动，利用传动模块和压力传感器将压力变化值传送到上位机作显示分析。实验表明该模拟器具有精度高、波形显示速度快的特点。

英文摘要：

To overcome the shortcomings occurred in the device research and development stage, calibration testing or teaching experiment for the invasive blood pressure measurement in the hu- man or animal experiments, a new design of an invasive blood pressure simulator was proposed. The simulator used a microcontroller to produce sine wave and a variety of human blood pressure waveform, which were delivered to the speaker to vibrate. The pressure changes via the driving module and the pressure sensor was then sent to the host computer for analysis. The experiment results showed that this simulator had high precision and displayed fast waveform.
