摘　　要：设计一种新型窦道造影注射装置,通过装置中设置的上活瓣和下活瓣内管,防止窦腔内脓液、血凝块或组织阻塞造影管,同时安装压力传感器,感知窦道内造影剂的充盈量,避免向窦道周围渗漏,从而完整、清楚显示窦道。新型窦道造影注射装置设计合理、操作简单,克服造影剂注射量不易把控的问题,对辅助临床诊断和治疗提供重要帮助,具有较高的临床推广及使用价值。To design a new type of sinus tract angiography injection device,through the valve inside the inner tube to prevent the sinus from being blocked by pus,blood clot or tissue,and a baroreceptor was installed to sense the filling of the sinus to prevent the sinus from leaking out,thus the sinus could be displayed clearly and completely.The new sinus injection device was reasonable in design,simple in operation,and can overcome the difficulty of controlling the amount of contrast medium injection,provides important help for auxiliary clinical diagnosis and treatment,and has high clinical promotion and use value.
