Abstract

本实用新型是用于向子宫腔移植精子及胚胎的医疗器械。宫腔移植管是由对人体无毒的透明塑料制成的中空管。其内径顶端细,末端粗。顶端外周有一球形膨大部,以便易于通过宫颈管。末端内径与1ml注射器乳头外径相适应,以便能与1ml注射器相适配。移植管中段有一可以滑动的塑料环,用于指示应插入宫颈管及宫腔的深度。

Description

宫腔移植管
本实用新型是用于向子宫腔移植精子及胚胎的医疗器械。
辅助生育技术的主要手段是人工授精及体外受精—胚胎宫腔内移植。人工授精是用移植管将精子经宫颈注入宫腔,使精子与卵子在体内受精;体外受精—胚胎宫腔内移植是用移植管将在体外受精形成的胚胎经宫颈移植入宫腔。因此,移植管是人工授精、体外受精—胚胎宫腔内移植的重要医疗器械。目前国内市场移植管种类很多,但均为进口,价格昂贵。此外,有的移植管不易通过宫颈,有的由套管及内芯组成,操作不便。
本实用新型的目的是提供一种用于人工授精及体外受精—胚胎宫腔内移植,易于通过宫颈,便于操作的宫腔移植管。
上述目的是通过下述措施实现的。宫腔移植管是由对人体无毒的透明塑料制成的中空管。中空管的内径顶端细,末端粗。顶端外周有一球形膨大部,以便在通过宫颈时能滑过宫颈管弯曲或宫颈隐窝形成的障碍,使移植管易于通过宫颈管进入宫腔。末端内径与1ml注射器乳头外径相适应,以便能与1ml注射器相适配。移植管中段有一可以滑动的塑料环,用于指示宫腔移植时移植管应进入宫腔及宫颈管的深度。
附图为本实用新型结构示意图。图中1为宫腔移植管顶端及膨大部,2为宫腔移植管末端,3为用于指示插入深度的塑料环。
