Abstract

一种一次性引产用水囊,属于医疗器械,它由导管1和储水囊2构成,其中的储水囊2套在导管1外壁上并与导管1外壁固定密封连接,套在储水囊2中的导管1上开有一小孔3与储水囊2相通。本实用新型克服了以往引产工具操作复杂,注水量大且易回流的缺点,结构简单,易于操作,注水量小,避免了胎头移位、脐带脱垂等并发症的发生,减少了产妇的痛苦。

Description

一种一次性引产用水囊
本实用新型涉及一种医疗器械,特别是一种引产工具。
人们在进行妇产科引产手术时,大都采用药物引产和物理引产两种方法。药物引产时间较长,价格昂贵,且需专人护理。物理引产使用的引产工具多由医生临时制作,将导尿管与避孕套连在一起构成,它没有固定结构,临时制作非常麻烦,手术中需几人同时操作。近几年也有一次性引产水囊在手术中应用,其结构大多是将储水囊与导尿管的一端连接,注水量至少需250ml,一般则需300-500ml,注水后,液体使储水囊膨胀为前粗后细的汽球形,容易使液体倒流回导管,储水囊张力减小,对宫颈的压迫和扩张作用不足,尤其是可导致胎膜破裂、胎头移位、脐带脱垂等严重并发症,因此临床应用效果不佳。
本实用新型的目的在于提供一种结构简单,操作容易,注水量少的引产工具。
本实用新型是一种一次性引产用水囊,由导管1和储水囊2两部分组成,其特征在于储水囊2呈环形套在导管1前半部分的外壁上,并与导管1外壁固定密封连接,套在储水囊2中的导管1上开有一小孔3与储水囊2相通。
所述的导管1靠近储水囊2的一端是封闭的,另一端安装有单向注射阀4。
下面结合附图对本实用新型进行详述:
附图1为该引产用水囊的结构示意图;
附图2为该引产用水囊的使用状态图。
图中:1、导管,2、储水囊,3、小孔,4、单向注射阀。
本实用新型的导管1可选用硅胶、乳胶、橡胶制成,储水囊2可选用天然乳胶制成。使用时将该实用新型带有储水囊2的一端放置到子宫壁与羊膜腔之间,将注射器安装在另一端的单向注射阀4上,用注射器向导管1内注射适量液体,液体经导管1上的小孔3流入储水囊2中,使储水囊2膨胀,对子宫及宫颈管产生机械刺激,引起宫缩,使胎儿排出。
本实用新型的主要优点在于:制作容易,使用方便,注水量仅需30-50ml,储水囊注水后前后粗细均等,不会使液体倒流回导管,储水囊张力增大,对子宫颈内口的压迫及对宫颈管的扩张作用充分,因此促宫颈成熟效果好,不会产生胎头移位、脐带脱垂等并发症,减少了产妇痛苦。
