输卵管诊治仪主要由自动注射、信号检测及处理、限压报警及自动保护三部份组成,如图1。自动注射系统能将生理盐水匀速注入子宫,探头检测出宫内压力,再经压电变换放大后送入显示器或记录仪,根据显示的结果或记录的压力的曲线来检测输卵管的通畅程度。重复注射可治疗输卵管轻度粘堵及 Tubal diagnosis and treatment instrument mainly by the automatic injection, signal detection and processing, voltage limiting alarm and automatic protection of three parts, as shown in Figure 1. Automatic injection system can saline injected into the uterus at constant speed, the probe detects intrauterine pressure, and then transformed into the piezoelectric transform into the monitor or recorder, according to the results displayed or recorded pressure curve to detect tubal patency. Repeated injection can treat tubal mild sticking and blocking
