摘　　要：目的:通过对体外冲击波碎石机水路系统改进提高碎石效率。方法:在冲击波发生器的进水管道上增加一个具有加热功能的储水囊和密闭的水箱,储水囊内加注制备的具有防锈防腐功能的无气水,并且与自来水完全分离;利用自来水的压力控制无气水填注到冲击波发生器内,在排水排气管道和储水囊之间连接一个临时储水箱和单向通水阀。结果:该改进后碎石机可以反复利用制备的无气水填注冲击波发生器内,减少冲击波体外传导途径内的气体含量,减少气泡形成,提高冲击波传导效率进而提高碎石效率,简化碎石操作程序使碎石过程更加合理。结论:该体外冲击波碎石机水路改进方法简单、成本低廉、值得推广应用。Objective To increase stone-breaking efficiency by improving waterway system of extracorporeal shock wave lithotripsy. Methods A water-storing bag, which possessed warm-up function and was filled with anticorrosive and antirust no-air water, and a sealed water tank were added to water-entering pipeline of shock wave generator. Water pressure pressing water-storing bag was utilized to control no-air water to be filled into shock wave generator to minimize bubble forming in shock wave outer conduct passway. Meanwhile, a temporary water-storing tank and a single-directed valve were added between pipelines and water-storing bag. Results After improving, lithotripsy could recycle no-air water to be filled into shock wave generator. It not only increased shock wave conducting and stone breaking efficiency, but also decreasee air content in shock wave generator and outer conduct passway, and decreased bubble forming, thus reducing complication in more rational procedures. Conclusion The method of improving waterway system of extracorporeal shock wave lithotripsy is simple, cheap, effective and worth popularizing.[Chinese Medical Equipment Journal,2008,29（4）：62-63]
