The utility model discloses a water pipe to prevent uterine contrast injection liquid reflux, including charge and set up in the back of the head of the injection connecting pipe and air connection pipe, is arranged in the charge separated main cavity channel and balloon cavity channel, the main channel is connected with the cavity injection pipe is communicated with the balloon. The cavity channel and inflating connection pipe is communicated with the head is arranged on the front end is connected with the passage through the balloon balloon; the injection connecting pipe and the connecting pipe are respectively provided with a pneumatic clamping device for gas injection pressure keeps the main passage of injection pressure and balloon cavity channel. The utility model by inflating connection pipe and the injection connecting pipe are respectively connected with the clamping device before removing the syringe, inflating connection pipe and the injection pipe connection is still in the sealed state, inflating connection pipe and the injection tube connected by the clamping device between the connecting tube and again closed inflating liquid injection and connecting tube. Then remove the syringe, thereby avoiding air connection pipe leakage and was injected into the uterine cavity of the liquid outflow.

技术介绍
近年来,育龄妇女不孕逐年增加,其中输卵管阻塞因素为最主要的病因,特别是在继发性不孕症中比例可高达66.67%。输卵管通畅检查方法很多,包括影像学检查、输卵管通液及输卵管镜腹腔镜检查,影像学检查包括子宫输卵管造影、子宫输卵管超声造影等。输卵管通液简便易行,但存在较大的盲目性和不准确性,目前作为一种初筛手段。腹腔镜直视下输卵管通液检查目前被认为是最可靠的检查方法,但由于腹腔镜检查的有创性和价格昂贵,目前更倾向于作为治疗手段。近年来发展的子宫输卵管超声造影亦是根据加压充盈宫腔造影,但超声图像对于临床医生来说比较抽像不易理解。而传统子宫输卵管造影(Hysterosalpingography,HSG)可显示宫腔和输卵管形态、对比剂充盈和通畅情况,图像一目了然,目前仍是诊断输卵管阻塞性不孕的首选检查方法以及金标准。但由于这种检查方法是在X线下操作,对医生、患者均有辐射损伤。目前子宫造影管所用的单球囊无注药控制阀硅胶造影管,包括软管,软管中设有管芯,软管 ...
