Description

配备有组织长入套管的外部终端装置
技术领域
本发明涉及一种可用于例如血液透析、腹膜透析和化学疗法中的外部终端装置。该外部终端装置配备有组织长入套管(tissue-ingrowth cuff)。
背景技术
定位在永久性中心静脉导管上的目前的套管包括粘在导管本身上的涤纶带,并且具有机械功能和生物功能。
从机械的角度来看,通常是环形垫的这些套管是身体外部的材料制成的。当被定位在皮下组织中时,套管被结合到身体中,即使产生倾向于将它们与周围组织隔离的反应。结果是形成了疤痕组织,该疤痕组织渗入涤纶本身的细丝中,有效地将其阻挡在该位置,最终获得了将套管固定在适当位置的粘附力,防止其向外滑动并且从而避免了导管本身的意外排出。
从生物学的角度来看,这种疤痕组织同时形成了一种屏障,阻碍细菌菌落沿着导管所在的皮下隧道的行进,该细菌菌落不可避免地会到达导管的浸入到血液中的部分并引起感染,首先是局部的,并且然后是全身性的感染。
然而,所有这些都非常受限于套管的小尺寸,在现有技术中,套管通常不是很宽。它们的小宽度还导致随着时间的推移,由于对使用这些导管的患者的护士护理,疤痕组织的形成逐渐产生,失去其机械功能,随后导致导管的释放及其排出。
US 2012/0209206 A1公开了一种组织长入套管,用于稳定植入的导管以防止移动。套管一旦移动到其所需位置就由外科医生致动,以抓住导管。套管包括两个本体部分,这两个本体部分在联接之前可沿导管单独地滑动,但可通过互补的抓握部分围绕导管彼此附接。在导管植入后,组织长入材料在皮下隧道内固定到套管的朝外的表面,从而锚固导管以防止移动。
引用文献中描述的套管具有能够定位在外科医生期望的位置的优点。然而,套管的锚固仅依靠它周围的长入的组织。
发明内容
本发明的一个目的是避免连接到外部终端装置的导管从外科医生安装它的皮下隧道中的位置移位。
该目的通过配备有组织长入套管的外部终端装置来实现,如所附权利要求所定义。
有利地,根据本发明的套管包括两个不同的涤纶带,而不是仅一个。
与当今市场上的导管相比,涤纶带的宽度相当可观。正如很容易理解的那样,这已经大大增加了套管本身的机械抓握。
从生物学的角度来看,很明显,这种相当大的宽度也会对细菌的行进产生更大的障碍,细菌因此必须行进很长的路径才能克服它并到达导管的浸入血液中的部分。
在两个带之间具有刚性聚砜(polysulfone)环,该刚性聚砜环在底部配备有呈45°角的钩形的两个小突起。该两个小突起在植入时由于从外部对其施加的简单且轻微的压力而被锚固到下面的肌肉带上:这加强并稳定了套管本身的机械抓握。
附图说明
在借助附图以非限制性示例的方式示出的外部终端装置的一个优选但非排他性的实施例的本描述中,进一步的特征和优点将变得最明显,在附图中:
图1示出了根据本发明的装置的一个实施例处于关闭位置的整体立体图;
