摘要
在电外科手术后能够准确、实时测量生物体腔道的爆破压数值,是判定微创电外科手术成功与否的重要指标,因此针对生物体腔道设计了一种爆破压检测系统;系统基于LabVIEW以及DAQ数据采集卡,实验结果表明此套系统能够实现快速、便捷、准确地测量、显示和存储爆破压数值,具有实际的临床应用价值。
Measuring the burst pressure of organism＇s orifice accurately and simultaneously after electrosurgery is an important factor to evaluate the result of minimally invasive surgery. Within the system, stepping motor can be controlled in LabVIEW to push syringe to fill the tissue with water. The pressure transmitter will transfer the pressure into voltage signal, and send through DAQ, then process the data with oversample method, display and store the data in LabVIEW. The burst pressure of chicken intestine is （12. 0± 2.0） kPa, The result shows that this system can measure, display and store burst pressure quickly, conveniently and accurately.
