技术领域
本发明涉及流体输注领域，具体而言，涉及一种用于对患者进行给药的贴附式流体输注装置及配合使用的输注针保护器。
背景技术
糖尿病是一种以高血糖为特征的代谢性疾病。高血糖一般是由于胰岛素分泌缺陷或其生物作用受损，或两者综合作用引起。糖尿病患者体内长期存在的高血糖会导致多个身体器官(例如，眼、肾、心脏、血管、神经系统等)的慢性损害、功能障碍。目前，胰岛素泵是一种成熟的糖尿病治疗方案，包含输注组件的贴片式流体输注泵是完成输注的一种常用耗材。
通常，贴片式流体输注泵包括壳体、储液室、输注组件等，其中输注组件与储液室流体连通，用于将储液室内的输注流体输送至患者体内，输注组件包括输注针，输注针能够从壳体伸出并刺入患者皮肤以输送流体。在贴片式流体输注泵使用之前和使用之后，暴露于外界的输注针容易被折断或刺伤患者等，这会对产品本身和使用者都会造成一定的危险，此外，在向储液室内充填流体(药物)时，暴露于外界的输注针还容易泄露流体。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明 作进一步地详细描述。需要注意的是，本发明并不限于附图所示的部件构造和/或布置，在不脱离本发明实质的情况下，还可以对本发明的各种实施方式进行各种不同的组合。
本文公开的实施方式提供了用于贴附式流体输注装置的输注针保护器，从而保证贴附式流体输注装置的使用安全性，又可提高易用性和使用舒适度。本文公开的实施方式还提供了与这种输注针保护器配合使用的贴附式流体输注装置。
下面结合附图描述本发明的输注针保护器和贴附式流体输注装置的具体实施方式。
图1A至图1C是输注针保护器和贴附式流体输注装置的概览示意图。如图1A至图1C所示，本实施方式提供了一种输注针保护器1和一种贴附式流体输注装置2，两者可以配合使用。输注针保护器1包括本体11、针密封部12和针弯折部13。贴附式流体输注装置2用于对患者进行给药(例如胰岛素等药物)，可以是微量输注泵，包括：壳体21、储液室22、包括输注针23的输注组件。其中，壳体21的下表面适于贴附患者皮肤；储液室22位于壳体21内且用于容纳输注流体；输注组件与储液室22流体连通，用于将储液室内的输注流体输送至患者体内，输注针23能够从壳体21的下表面伸出并刺入患者皮肤。贴附式流体输注装置2的壳体21上设置有位于输注针23伸出的位置处分第一凹部24，壳体21还设置有与第一凹部24相连接的第二凹部25。
图2是图1中的输注针保护器的示意图。结合图2可知，输注针保护器1的针密封部12设置于本体11上，适于收纳并密封贴附式流体输注装置2的输注针23。这样，在向贴附式流体输注装置2的储液室22填充输注流体(例如胰岛素之类的药物)时，针密封部可以密封输注针23，即使储液室内的活塞移动，输注流体也不会在输注针23处发生泄露。
输注针保护器1的针密封部12为自本体11的表面向外延伸的第一凸起，例如，可以是粘接在本体11的表面上的弹性密封件，例如橡皮隔膜或硅胶隔膜等可以密封包裹住输注针23的部件。输注针保护器1的第一凸起(针密封部)12与贴附式流体输注装置2的第一凹部24相匹配，输注针23可以收纳并密封在第一凸起12内。可选地，针密封部12也可以是其他可以收纳并密封输注针23的部件，可以根据需要设置在输注针保护器1的本体11的任何 位置。
输注针保护器还包括固定部14，适于将输注针保护器1与贴附式流体输注装置2相固定。输注针保护器的固定部14为自本体11的表面向外延伸的第二凸起，而贴附式流体输注装置2的壳体21上设置有凹槽27，第二凸起14与凹槽27相匹配，从而固定输注针保护器1与贴附式流体输注装置2。第二凸起与相匹配的凹槽的位置可以根据实际需要来设置。例如，第二凸起可以设置在第一凸起的周围，以便于加强输注针保护器1的第一凸起与贴附式流体输注装置2的第一凹部24之间的配合。可选地，也可以通过其他方式使输注针保护器1与贴附式流体输注装置2相固定，例如卡扣结构等。
输注针保护器1的针弯折部13设置于本体11上，适于在使用后处理贴附式流体输注装置2时弯折输注针23。例如，针弯折部13可以为卡槽，与输注针23相匹配。卡槽可以设置在本体11任一面的边缘处，或者任一面的中间，任何位置均可以，可以根据需要设置1个、2个或多个卡槽。可选地，针弯折部13也可以是其他可以弯折输注针的形状部件，可以根据需要设置在输注针保护器1的本体11的任何位置。
图3A至图3B图示了使用输注针保护器弯折贴附式流体输注装置的输注针时的示例性过程。图4是图3A至图3B中的贴附式流体输注装置的部分放大示意图。结合图3A至图4可知，在使用后处理贴附式流体输注装置2时，使用输注针保护器的针弯折部13弯折输注针23，被弯折的输注针23可收纳入贴附式流体输注装置2的第二凹部25中，第二凹部内还设置有输注针锁26，适于锁定被弯折的输注针。这样，贴附式流体输注装置2在使用3～5天后，患者可利用输注针保护器1上的卡槽结构，将针弯折并收纳入第二凹部25中，并通过输注针锁26固定收纳入的输注针23，从而在处理过程中保护针。
图5图示了使用输注针保护器触发贴附式流体输注装置的示例性过程。如图5所示，输注针保护器1还包括触发部15，适于触发贴附式流体输注装2的针插入机构，触发部设置于11本体上，为自本体11的表面向外延伸的第三凸起，其体积细小，通常成小半径的圆柱体状。可选地，触发部15也可以是其他可以触发输注针的形状部件，可以根据需要设置在输注针保护器1的本体11的任何位置。
贴附式流体输注装置2还包括位于壳体21内部的针插入机构(未示出)， 在壳体21上设置有通向针插入机构的孔28，输注针保护器的触发部15可以穿过孔28以触发该针插入机构。触发部15可以与孔28相匹配或触发部15的直径微小于孔28的直径。这样，在将输注装置贴附在患者身上后，通过输注针保护器的触发部15而不是手指按钮来触发针插入机构，从而驱动输注泵将针插入患者皮下输注药物(如胰岛素)，触发部15体积细小，可以避免触发失败或在错误时间触发针插入机构。
应当指出的是，尽管上述装置的各方面是按特定的顺序和特定的结构布置进行描述，但这仅用于举例说明，对本发明不构成限定，所请求保护的主题并不限于所述的顺序和结构布置。本领域技术人员应当理解，在不脱离本发明实质的情形下，可以对发明做出各种修改，并且可以进行等同替换。因此，本发明所请求保护的主题并不限于上述公开的具体实施方式，还可包括落入权利要求保护范围的所有技术方案以及与之等同的技术方案。此外，在权利要求中，除非另有说明，所有的术语应按最宽泛合理的意思进行理解。
