【技术实现步骤摘要】
本技术涉及气球形导管的
,具体涉及一种导尿管。
技术介绍
医用导尿管是现代医疗实践中最常用的医疗器材之一,其目的为确地记录尿量、解除尿潴留、保持阴部清洁。现有的导尿管结构包括柔性的管体,管体靠近进液口(膀胱内的尿液从进液口中流入管体)的位置设有气囊,管体为两腔或三腔结构。两腔的结构中,包括了引流腔和注液腔,引流腔用于排尿引流,注液腔用于向气囊注入液体将导尿管固定在膀胱防止滑脱。三腔的结构中,除了包括引流腔和注液腔之外,还包括冲洗腔,冲洗腔用于膀胱灌注冲洗。使用导尿管时,需要将气囊插入膀胱中,然后向气囊注入液体,使其固定。现有引流腔的进液口均位于气囊之前,当将导尿管插入膀胱后,引流腔的进液口处于高位,而气囊处于低位,尿液中的血块、石头,脓,坏死组织容易沉积在气囊上,而不能有效地排出。现有的引流腔为开放式设计,没有阻流装置,引流腔上必需接尿袋,否则不仅很容易污染衣物,而且细菌容易沿引流腔繁殖使膀胱感染。现有的尿袋与引流腔是通过插接的方式固定,即尿袋上有一个锥形的尿袋接头,将尿袋接头插在引流腔的开口处固定。采用上述插接方式非常地不牢固,特别是当尿袋中储存了一定液体有一定重量之后,尿袋很容易从引流腔内脱出。
技术实现思路
本技术提供一种两用无菌导尿管,以解决引流腔的进液口在使用时处于低位,引流腔的开放式设计容易导致膀胱感染,尿袋之间连接不牢固的问题。为达到上述目的,本技术的基础技术方案如下:一种两用无菌导尿管,包括管体,管体上设有气囊,管体内设有柔性的引流腔,所述气囊沿管体的周向设置,引流腔的进液口被气囊包围;引流腔上设有密封开关,所述密封开关包括密封座、盖体和支 ...
【技术保护点】
一种两用无菌导尿管,包括管体,管体上设有气囊,管体内设有柔性的引流腔,其特征在于,所述气囊沿管体的周向设置,引流腔的进液口被气囊包围;引流腔上设有密封开关,所述密封开关包括密封座、盖体和支杆,密封座的外缘周向密封连接在引流腔的内壁上,密封座上开有流道和通孔,支杆穿过通孔且与通孔滑动连接,支杆的一端连接在盖体上,盖体与引流腔的内壁连接,且盖体可将流道和通孔完全封闭,支杆的另一端与密封座之间设有压簧,压簧使盖体与密封座紧抵;引流腔的出液口处设有内螺纹。
