【摘要】 以相似理论为基础 ,建粒并验证了模拟人体胆道系统模型 ,以DZ - 5型振荡仪为压力波振荡源 ,采用微机A/D动态测试系统 ,在模拟人体胆道系统模型实验台上 ,开展了压力波传输规律、奥狄斯 (Oddis’)括约肌功能的研究 ,同时进行了振荡排石实验。验证并完善了理论分析提出的振荡排石机理。建议对失去括约肌功能的患者在振荡治疗时采取在预置T管中放置单向阀。振荡排石参数的优化、脉频对排石的影响有待进一步的探讨。更多还原

【Abstract】 In this Study, according to theprinciple of similitude, the model of bile duct system (that is BSM)has been simulated by transparent rubber and has been verified. Aspecific oscillator DZ-5 for the biliary system produced the pressure elastic waveswith differentwave shapes, frequency and amplitudes. A microcomputersystem are used to study the principle of the pressure elastic waves propagating in BSM and the function of Oddis sphincter, and then the experiment of removing gallstones on the experimental installation of BSM is carried out. Amechanism for movinggallstonesthat based on the theoreticalanalysis is verified by this study, and then to be perfected. It is suggested to put the one-way valve in T-type tube for patients whose sphincters loseeffectiveness. The optimum parameters of pressure elastic waves and the effect of pulse frequency on the removing gallstones have to be furtherdiscussed.更多还原
