Description

可安装在皮肤上的医疗装置
技术领域
本发明涉及一种可安装在皮肤上的医疗装置,其包括具有优选地通过粘垫可附着到使用者的皮肤上的底侧的安装板、医疗模块特别是分析物传感装置或药物施用泵、以及适于将医疗模块可释放地附着到安装板的与底侧相对的上侧上的卡合连接件。
背景技术
从WO 2009/125398 A2中已知这种医疗装置。在那里,该装置包括可附着在皮肤上的托架单元和流体分配单元,其中托架单元具有两个锁扣,并且通过锁扣32、34的操作将分配单元卡扣配合。为此,锁扣被构造为钩状突起,其容纳在分配单元的互补形状的沟槽中。然而,WO 2009/125398 A2没有公开使用者处置锁扣的细节,并且锁扣在插入分配单元时似乎易于断裂。这种断开的连接可能导致医疗装置的丢失,甚至患者可能不会注意到。
在此基础上,本发明的目的是进一步改进已知的医疗装置并提供一种易于使用的设计,该设计简化了使用者的操作,同时避免了组装故障。
发明内容
为了实现这一目的,提出了在独立权利要求中所述的特征的组合。本发明的有利实施例和进一步发展衍生自从属权利要求。
本发明基于通过避免机械运动路径中的干涉轮廓或接触来改善使用者交互的思想。因此,提出了一种建议,其中卡合连接件具有释放翼片,该释放翼片可由使用者操纵或推动以卸下医疗模块,其中该释放翼片从安装板向外突出并具有外部部分,该外部部分在所述安装板的底侧保留间隙以避免在使用或按压时发生干涉皮肤接触。以这种方式,允许释放翼片在皮肤接触之前移动,并且防止使用者对皮肤基台施加可能导致材料损坏的过大的力。此外,由于卡合连接件的可移动部分没有与皮肤接触,因此减少了用于插入医疗模块的工作量和力,因此还避免了安装板的弯曲或变形。结果,改善了使用者-装置交互,并且进一步支持了预期的医疗成功。
有利地,在安装板的底侧位于一个平面中或大体上为平面的情况下,释放翼片的外部部分应布置在该平面上方至少2 mm,优选至少5 mm的间隙距离处。以此方式,为翼片的无阻碍运动提供了足够的公差。
在另一种有利的构造中,在释放翼片具有连接至安装板的内部部分的情况下,该内部部分到由安装板的底侧(或在使用中由皮肤)所限定的平面的距离应小于外部部分到所述平面的距离。
就此而言,进一步有利的是,安装板的底侧和释放翼片的底侧分别限定一个平面,并且其中所述平面包括锐角。
优选地,所述锐角为至少5°,优选地为至少10°。
在另一个有利的实施例中,释放翼片的底侧平行于安装板的底侧。在这种平行构造中,释放翼片可以直接附着到卡合连接件的锁扣的直立部分。
一个特别有利的实施例进一步包括:释放翼片具有在使用中背对皮肤的直立圆周边缘。因此,当使用者将他的手指压在翼片上时,使用者会收到触觉反馈。此外,面向上的边缘避免了手指的意外滑动,从而支撑了更大的按压力。
在有利的实施例中,卡合连接件具有锁扣,锁扣与安装板连接并且在锁定位置与医疗模块接合,其中可通过操纵释放翼片而使锁扣向外倾斜,以便在释放位置与医疗模块分离。
为了提供机械上牢固的连接,锁扣具有钩部,该钩部适于卡合在医疗模块的凹部中。
为了支持将医疗模块施加到安装板上,卡合连接件具有被构造为将医疗模块引导至锁定位置的入口倒角,其中入口倒角布置为相对于安装板的底侧成锐角。
便于操作和改善结合的另一种可能性是,提供了用于附着医疗模块的固定支架,其中固定支架和卡合连接件布置在安装板的相对端部。
在又一种有利的构造中,安装板和释放翼片是一体成型的,优选为注塑成型的塑料部件。
根据权利要求1至12中任一项所述的医疗装置,在用于药物施用的有利构造中,配件可以布置在底板上,以提供优选用于医疗模块的套管组件的皮肤通道。
附图说明
下面,基于附图中示意性示出的实例进一步阐述本发明,其中
图1是包括具有改进的释放机构的安装基座的可穿戴医疗装置的透视图;
图2是图1的医疗装置的另一个透视图;
图3是医疗装置的释放机构的放大图;并且
图4是具有释放机构的另一实施例的安装基座的侧视图。
具体实施方式
参考图1,医疗装置10包括安装基座或安装板12;用于胰岛素施用的可穿戴贴片泵形式的医疗模块14;以及被形成为卡合连接件16的释放机构,其适于将医疗模块14可释放地附着在安装板12上,例如,在暂时不使用或更换的情况下,用于首次组装或拆卸。出于这一目的,卡合连接件16包括与医疗模块14的侧壁上的凹部或凹口20接合的锁扣18,以及释放龙头或翼片22,该释放龙头或翼片可以由使用者或患者向下推入底部自由空间或间隙24,从而允许翼片22在皮肤接触之前移动。
安装板12具有底侧26,该底侧可在输注部位处通过自粘垫30附着到使用者的皮肤28,该自粘垫在其粘附侧受到剥离箔32的保护。
如从图2中可以最好地看到,安装板12具有顶侧或上侧34,该顶侧或上侧在使用中背对皮肤28并且支撑医疗模块14。锁扣18和固定钩或支架36作为上侧34上的直立元件设置在长方形安装板12的相对端部。直立中空配件或插口38为套管组件(未示出)提供皮肤通道。
在锁扣18的结合区域处,翼片22模塑成型在安装板12的边缘上,使得翼片向外突出并且向上倾斜远离皮肤28,这将在下面更详细地阐述。有利地,翼片22具有平坦的基座部分40和在基座部分的背离皮肤28的自由外边缘上的直立圆周边缘42。
安装板12(包括其附接元件18、22、36、38)可以一体成型为连体塑料部件,例如,通过注塑成型。
如图3中进一步所示,释放翼片22的外部部分44在其底侧保留间隙24,使得允许释放翼片22在手指压力所施加的力的作用下移动而没有干扰,从而避免了与皮肤28或布置在其上的自粘垫30的接触。然后,当从垂直于平面46的方向看时,到由皮肤28所限定的平面46(或与其一致地由安装板12的平坦底侧26所限定的平面)的外部间隙距离应为约5 mm。
图3进一步示出了锁扣18具有钩部50,该钩部适于卡合在医疗模块14的凹部20中。钩部50设有入口倒角52,该入口倒角在医疗模块14被引入所示的锁定位置时引导医疗模块。出于这一目的,入口倒角52布置为相对于安装板12的底侧26成锐角。为了移除医疗模块14,可通过操纵释放翼片22使锁扣18向外(在图3中向右)倾斜,以便在释放位置与凹部20脱离。
在图3的实施例中,为了允许在干涉皮肤接触之前进行运动,翼片22的连接部分48到平面46的距离应该小于外部部分44到所述平面46的距离。这可以通过将翼片22的平坦底侧54布置为相对于皮肤28或平面46成锐角α而实现。优选地,所述角度α大于5°,例如,大约10°。
在图4的实施例中,相似的部分用如上文阐述的相似的附图标记表示。主要区别在于释放翼片22的设置方式,在这种情况下,释放翼片在其底侧以一定距离平行于安装板12底侧26,因此保持了具有恒定间隙24的自由空间。在这种构造中,释放翼片22可以直接附着到锁扣18的直立部分。
