脑积水患者通常通过分流术将多余的脑脊液(CSF)转移到身体其他部位进行治疗。超过40%的分流装置在头两年内失败。分流道梗阻是失败的主要原因之一(45%)，而梗阻的检测降低了翻修手术的复杂性。本文介绍了一种用于调车堵塞检测和流量测量的无线监测系统。利用沿分流导管的多个压力传感器构建了一台原型，用于检测堵塞的位置和流量。可通过定期监测流量来调整分流管中的阀门，以防止脑脊液过度引流或引流不足。流量测量准确率达90%以上。
Patients with Hydrocephalus are usually treated by diverting the excess Cerebrospinal Fluid (CSF) to other parts of the body using shunts. More than 40 percentage of shunts implanted fail within the first two years. Obstruction in the shunts is one of the major causes of failure (45 percent) and the detection of obstruction reduces the complexity of the revision surgery. This paper describes a proposed wireless monitoring system for clog detection and flow measurement in shunts. A prototype was built using multiple pressure sensors along the shunt catheters for sensing the location of clog and flow rate. Regular monitoring of flow rates can be used to adjust the valve in the shunt to prevent over drainage or under drainage of CSF. The accuracy of the flow measurement is more than 90 percent.
