Description
技术领域
本发明涉及用于施加于皮肤的输液装置的固定机构,所述固定机构使得输液装置可靠地固定在身体上的合适位置。
背景技术
小型化的输液装置例如用于糖尿病患者的门诊治疗,该输液装置直接用在皮肤的表面并且能够实现不连续的和舒适的佩戴。在将这种输液装置固定在皮肤表面上之后,其通常要附着在身体上4-5天,然后被完全或部分地去除。由患者自己将施药装置施加在皮肤表面上,以及将施药插管插入身体组织中。
在患者的日常使用中,期望能够临时地拆除输液装置或者至少输液装置的一部分,以便例如允许患者自由地从事体育活动,而且在泡澡或淋浴过程中不至于将计量装置的精密部分或电子元件暴露出来而与水产生不希望的接触。
为了能够临时地拆除输液装置,并且之后不需要再次把插管插入皮肤中,在已知的输液装置中是使导管头部能够从泵或施药装置拆下。该导管头部和插管形成留置定位器,该定位器设有合适的密封机构,在分离的状态下保持在身体组织中或保持在身体组织上。
专利说明书DE19912459C2描述了一种适配器形式的留置定位器,其能够借助于粘性的皮肤膏贴附到皮肤的表面上,并能够与计量装置连接以进行医疗液体的连续施用,或者与注射笔连接,或者与注射器针头流体连接。
如果施药装置或计量装置借助于这种留置定位器以机械方式连结,那么施药装置的静态不平衡(由于其结构的原因,不可能完全消除)会导致力或倾斜力矩产生,所述力或力矩取决于施药装置的定向,并且会限制戴着泵的患者的佩戴舒适感。对于戴着泵的患者来说,期望的是允许进行泵的个别定向,以便泵能够戴在身体上的合适位置。
发明内容
本发明的目的是,确保经可解除的插入连接和流体连接而与留置定位器连结的输液装置能够被舒适地固定在皮肤表面上的合适位置,并且在分离之后,能够安全地再次固定。该目的通过技术方案1的主题实现。
本发明涉及一种输液装置,其被戴在皮肤的表面上并施用医疗液体,施药装置被安装成能绕导向元件转动并且和导管头部建立可解除的连接。该导管头部借助于粘接剂固定在皮肤表面上,这对输液装置来说在现有技术中是已知的。
当施药装置连接到导管头部上时,它最初保持绕导向元件自由转动的状态。通过这种方式,戴着泵的患者能够穿戴舒适且考虑周全地个别定向他或她的施药装置。一旦施药装置被放置在期望的位置,就能借助位于底面周边区域的粘接剂进行定位和固定。以这种方式形成的第二固定区域使得能够引入加倍的力,从而总体上更好地定位在皮肤表面上。通过使用多片粘接剂,能进一步提高可靠性。
为了临时分离输液装置,例如为了在泡澡或淋浴过程中保护施药装置以免不期望地与水和湿气接触,而首先消除施药装置周边区域中的粘性附着。然后从连接器解除施药装置。
为了确保令人满意的粘性连接,在临时分离之后应在周边区域使用新的粘接剂。
在一个特定的优选实施例中,将膏状的粘接剂设置在设备的底面上,有效的粘性表面最初用保护膜覆盖。当要启用膏状的粘接剂时,必须去除该保护层。保护膜上按人体工程学设计的易撕片(tear-offtab)允许戴着泵的患者捏住它并将其撕掉。
在另一个实施例中,直到马上就要在输液装置上使用了,才将作为备用粘接剂而独立储备的粘接剂启用,并贴附到泵底面上的合适位置。
在另一个优选的实施例中,粘接剂通过一张或多张独立的背衬膜固定在设备的底面上。通过这种方式,能根据需要和在需要时,清除用过的粘接剂。
附图说明
图1示出了导管头部的侧视图。
图2示出了具有不同的粘接剂布置区的输液装置的底面,该粘接剂布置区位于周边区域。
具体实施方式
下面参考附图更加详细地说明本发明特定的优选示例性实施例。
图1示出了导管头部(1)的侧视图,该导管头部借助于涂敷在底面的粘接剂(1a)固定在皮肤的表面上,插管(1b)从该导管头部穿进身体组织(6)。在导向元件(c)上方推动胰岛素泵形式的施药装置,而流体地和机械地连接。该胰岛素泵(2)保持可转动的状态并且绕适配器(1c)自由转向,这允许戴着泵的患者对泵进行适当定向,以便施加在身体上。只有在戴着泵的患者已经借助于粘接剂(1a)将该泵定位在合适的位置之后,该输液装置才完全固定在身体上。通过额外获得的固定或力的引入实现可靠的紧固。
在分解视图中可以看到保护膜(4)的布置区、呈皮肤亲和性膏(3)的形式的粘接剂的布置区、以及背衬膜(5)的布置区。
图2示出了具有不同的粘接剂布置区的输液装置的底面,该粘接剂布置区位于周边区域(2a)。粘接剂布置区(3a)由粘性膏构成,该粘性膏适合于小的重力和小的加速力。粘接剂布置区(3b)包括多片粘接剂,该多片粘接剂能够吸收比粘接剂布置区(3a)更大的力和加速分量。为了使保护膜(4)或背衬膜(5)更容易操作,由膜的轮廓形成捏持片。可以在周边区域(2a)多次提供所述的粘接剂布置区,使得每一次重新进行的连接过程都可获得未使用过的粘接剂。
