正常人身体中的胰腺可自动检测人体血液中的葡萄糖含量，并自动分泌所需的胰岛素/胰高血糖素。而糖尿病患者胰腺的功能出现异常状况，无法正常分泌人体所需胰岛素。因此糖尿病是人体胰腺功能出现异常而导致的代谢类疾病，糖尿病为终身疾病。目前医疗技术尚无法根治糖尿病，只能通过稳定血糖来控制糖尿病及其并发症的发生和发展。
糖尿病患者在向体内注射胰岛素之前需要检测血糖。目前多数的检测手段可以对血糖连续检测，并将血糖数据实时发送至外界设备，便于用户查看，这种检测方法称为连续葡萄糖检测(Continuous Glucose Monitoring，CGM)。该方法需要检测装置贴在皮肤表面，将其携带的传感器刺入皮下的组织液完成检测。

以下对示例性实施例的描述仅仅是说明性的，在任何意义上都不作为对本发明及其应用或使用的任何限制。这里对于相关领域普通技术人员已知的技术、方法和装置可能不作详细讨论，但在适用这些技术、方法和装置情况下，这些技术、方法和装置应当被视为本说明书的一部分。
应注意，相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义或说明，则在随后的附图说明中将不需要对其进行进一步讨论。
图1为本发明实施例分析物检测装置安装单元的外部结构示意图。安装单元100的外部结构包括壳体101和保护盖102，壳体101用于承载内部结构件。安装单元100在使用时，靠近用户皮肤的一端为近端，远离皮肤的一端 为远端。在壳体101的近端设置有第一开口。保护盖102用于对壳体101的内部结构和内部结构件进行保护、密封以及防触发。
壳体外部
图2a为本发明实施例壳体的外部结构示意图，图2b为保护盖的结构示意图。保护盖102包括外盖体1021、卡箍1022和内盖体1023。外盖体1021远端方向设置有第二开口，第二开口面向第一开口。在第二开口，外盖体1021与卡箍1022通过可折断的立柱10211连接，立柱10211按一定的间距分布在外盖体1021和卡箍1022之间。外盖体1021相对于卡箍1022旋转时，立柱10211可被折断，外盖体1021与卡箍1022分离。
外盖体1021内侧设置有内螺纹10212，对应的，内盖体1023外侧设置有外螺纹10231，内螺纹10212与外螺纹10231可配合连接，以将外盖体1021与内盖体1023连接在一起并保持固定。

在本发明其他实施例中，外盖体1021与内盖体1023之间也可以摩擦配合或者卡扣配合实现固定连接。
在本发明其他实施例中，卡箍1022与壳体101之间也可以通过摩擦配合、卡扣配合或者螺纹配合实现连接。
壳体内部
图3为本发明实施例分析物检测装置安装单元的爆炸结构示意图。图中虚线表示各结构件的安装配合关系。分析物检测装置安装单元100的内部结构件包括平行滑块模块103、分析物检测装置104、辅助针模块105、触发模块106和弹性模块107，弹性模块107包括第一弹性件1071和第二弹性件1072。
分析物检测装置104与安装单元100不仅限于图3所述的配合关系。在本发明一些实施例中，在安装前，分析物检测装置104内置于安装单元100，用户在使用时，从包装盒中取出安装单元100即可以将分析物检测装置104安装到人体皮肤表面。在本发明另一些实施例中，在安装前，分析物检测装置104与安装单元100处于分离状态，即用户从包装盒中需要分别取出安装 单元100和分析物检测装置104，然后将分析物检测装置104装配到安装单元100中后，才可以将分析物检测装置104安装到人体皮肤表面。
图4为本发明实施例壳体101的内部结构示意图。
在本发明实施例中，壳体101内设置有至少两个第一卡扣1012，第一卡扣1012与壳体101一体成型，并向壳体101的近端凸出。第一卡扣1012为柔性材料，末端可向壳体101的外侧弯折或者弯曲。
在本发明优选实施例中，第一卡扣1012的数量为两个，对称分布在壳体101内部，彼此间的角度间隔为180°。
在本发明其他优选实施例中，第一卡扣1012的数量为三个或者四个，对称分布在壳体101内部，彼此间的角度间隔为120°或者90°。第一卡扣1012的数量也可以是五个或者更多，在此不作限制。
在本发明实施例中，壳体101内还设置有至少两个限位槽1013、至少两个卡槽1014以及一个辅助针限位槽1015。
在本发明实施例中，限位槽1013包括至少两条凸出于壳体101内壁的肋板。在本发明优选实施例中，肋板彼此平行，相邻的肋板中间形成凹槽。

在本发明实施例中，卡槽1014包括两个卡槽位，即第一卡槽位10141和第二卡槽位10142，如图10a所示，第一卡槽位10141相对于第二卡槽位10142靠近于近端。
在本发明优选实施例中，限位槽1013、卡槽1014的数量为两个，对称分布在壳体101内部，彼此间的角度间隔为180°。
在本发明其他优选实施例中，限位槽1013、卡槽1014的数量为三个或者四个，对称分布在壳体101内部，彼此间的角度间隔为120°或者90°。限位槽1013、卡槽1014的数量也可以是五个或者更多，在此不作限制。
平行滑块模块
图5a为平行滑块模块103远端面的结构示意图，图5b为平行滑块模块103近端面的结构示意图，图5c为平行滑块模块103设置限位卡块1036的结构示意图。
在本发明实施例中，平行滑块模块103的远端面1031设置有向远端凸起的圆形槽1032，圆形槽1032为内部掏空的圆柱结构，其内径为d1。在圆形槽1032的侧壁上向远端伸出至少两个滑块卡扣10321，滑块卡扣10321的卡扣部为平面或者近似平面，并与水平面呈固定夹角，其延长端m0汇聚在远 端。
在本发明实施例中，滑块卡扣10321为柔性材料，因此可向圆形槽1032的外侧弯曲或者弯折。
在本发明其他实施例中，滑块卡扣10321可直接设置在平行滑块模块103的远端面，而不需要圆形槽结构。
在本发明实施例中，圆形槽1032内靠近远端面1031的一端还设置有一段凸台10322，凸台10322为内部掏空的圆柱体结构，其内径为d2，可以理解的是d1＞d2。内部掏空结构的圆形槽1032和凸台10322形成一个通孔10323，从平行滑块模块的远端面1031贯穿到近端面1034。
在本发明优选实施例中，滑块卡扣10321的数量为两个，对称分布在圆形槽1032的侧壁上，两个滑块卡扣10321彼此间的角度间隔为180°。
在本发明其他优选实施例中，滑块卡扣10321的数量可以为三个或者四个，对称分布在圆形槽1032的侧壁上，滑块卡扣10321彼此间的角度间隔为120°或者90°。滑块卡扣10321的数量也可以是五个或者更多，在此不作限制。
继续参照图5a，在本发明实施例中，平行滑块模块103的远端面1031侧边设置有至少两个第二卡扣1033，第二卡扣1033对称分布在远端面1031侧边，彼此间的角度间隔为180°。
在本发明其他实施例中，第二卡扣1033的数量为三个或者四个，对称分布在远端面1031侧边，彼此间的角度间隔为120°或者90°。第二卡扣1033的数量也可以是五个或者更多，在此不做限制。在安装单元100中，第二卡扣1033与第一卡扣1012耦合。第二卡扣1033的位置和数量与第一卡扣1012一致。
参照图5b，在本发明实施例中，平行滑块模块103的近端面1034侧边设置有至少两个T型结构1035，T型结构1035的竖直部连接于近端面1034，水平部包括T型结构滑块10351和T型结构卡扣10352，T型结构滑块10351朝向平行滑块模块103的外侧，并且凸出于平行滑块模块103的外圈；T型结构卡扣10352朝向平行滑块模块103的内侧，并且凸出于平行滑块模块103的内圈。
在安装单元100中，T型结构滑块10351位于限位槽1013内，以限制平行滑块模块103的位置，并防止平行滑块模块103在安装单元100内发生转动。T型结构滑块10351的数量及位置与限位槽1013一致。平行滑块模块 103向近端运动过程中，T型结构滑块10351在限位槽1013内滑动。
在本发明优选实施例中，T型结构1035的竖直部为柔性材料，竖直部与水平部一体成型，水平部可绕竖直部弯折或者弯曲。
在本发明其他优选实施例中，T型结构1035的竖直部为弹性材料，例如弹簧、弹片等，水平部通过焊接或者热熔等工艺与竖直部固定连接，水平部也可绕竖直部弯折或者弯曲。
参照图5c，在本发明其他实施例中，在平行滑块模块103的内圈上还设置有限位卡块1036，限位卡块1036用于限位分析物检测装置104，以及防止分析物检测装置104发生旋转偏移，具体将在下文描述。
分析物检测装置
图6a为本发明实施例分析物检测装置104的结构示意图，图6b为本发明实施例分析物检测装置104的另一种结构示意图，图6c为本发明实施例分析物检测装置104固定在平行滑块模块103上的结构示意图，图6d为图6a的A-A’剖面结构示意图，图6e-图6h为导电胶条1043的不同使用方式示意图。
结合参照图3，在本发明实施例中，分析物检测装置104包括外壳1041、发射器(图中未示出)、传感器1042、电池(图中未示出)和设置在外壳1041内并与传感器电耦合的内部电路(图中未示出)。传感器1042用于检测用户体液分析物参数信息，通过内部电路将上述分析物参数信息传递至发射器，再由发射器发送至外界设备200。
在本发明优选实施例中，在分析物检测装置104安装到用户皮肤表面前，以第一频率f1向外界设备200发射信号，安装到用户皮肤表面后，以第二频率f2向外界设备200发射信号，第二频率f2大于第一频率f1。在本发明进一步优选实施例中，第一频率f1为0～12次/小时，第二频率f2为12～3600次/小时。
在本发明更优选实施例中，第一频率f1为0次/小时，即在分析物检测装置104安装到用户皮肤表面前，不向外界设备200发射信号，这样可以节省安装前分析物检测装置104的电量消耗。
在本发明实施例中，外壳1041包括上外壳体10411和下外壳体10413，上外壳体10411和下外壳体10413拼接形成内部空间。传感器1042包括体外部分(图中未示出)和体内部分(图中未示出)，体外部分、发射器、电池和内部电路设置在内部空间中，体外部分与内部电路电耦合。体内部分上设置 有电极、膜层等结构，刺入用户皮下可以对分析物参数信息进行检测。体内部分刺入皮下时，需要有正确的角度，例如垂直于皮肤表面刺入。在分析物检测装置104寿命终止后，将其从用户皮肤表面取下，整体抛弃。
在本发明实施例中，下外壳体10413包括贯穿的第一通孔10414，对应的，在第一通孔10414的轴线上，上外壳体10411包括贯穿的第二通孔(图中未示出)，体内部分穿过第一通孔10414到外壳外部，以便于刺入用户皮下。
在本发明其他实施例中，在体内部分的轴线上，上外壳体10411设置有自密封构件，自密封构件初始为密封状态，自身具备一定的弹性和柔软性，并且可以被辅助针1052刺穿，例如硅胶、丁睛橡胶等。在安装单元100中，辅助针1052穿刺自密封构件，自密封构件会紧密包围辅助针1052的侧壁，不会留存缝隙或者开口，在使用安装单元100后，辅助针1052退回，与分析物检测装置104分离后，自密封构件会恢复到密闭的状态，而不会留下开口或者通孔，可以对分析物检测装置104形成良好的密封。
在本发明其他实施例中，在下外壳体10413的体内部分的周围设置有自密封构件，体内部分穿过自密封构件，自密封构件包围体内部分，自密封构件可为下外壳体10413提供密封保护，防止在体内部分刺入皮下时，血液喷射、浸入到分析物检测装置104中，同时也能起到防水的效果。
在本发明其他实施例中，可以在上外壳体10411和下外壳体10413同时设置自密封构件，也可以在其中之一设置自密封构件。在其中之一设置自密封构件时，另一个外壳体上设置有供辅助针1052穿过的通孔。
在本发明实施例中，位于下外壳体10413上的自密封构件是不透光材料的，防止外界光线通过自密封构件照射到分析物检测装置104内部而触发光敏元件。
在本发明实施例中，位于上外壳体10411上的自密封构件可以是透光材料的，在分析物检测装置104被弹射后，外界光线可以穿过自密封构件照射到分析物检测装置104的内部，以触发光敏元件。
在本发明实施例中，上外壳体10411的侧边包括对应于T型结构卡扣10352的卡孔10412，这里“对应”是指卡孔10412的位置、数量与T型结构卡扣10352一致。在安装单元100中，上外壳体10411与近端面1034贴合，T型结构卡扣10352与卡孔10412形成卡扣连接，分析物检测装置104被固定在平行滑块模块103上。当T型结构的水平部绕竖直部弯折或者弯曲时，T型结构卡扣10352与卡孔10412的卡扣连接解除，分析物检测装置104与 平行滑块模块103分离。因此在安装单元100中，分析物检测装置104与平行滑块模块103为可释放连接。
在本发明实施例中，卡孔10412与T型结构卡扣10352相对应，使得分析物检测装置104固定在平行滑块模块103上时，还可以同时起到定位的作用。分析物检测装置104的外壳体为圆形，在出厂前将分析物检测装置104安装到平行滑块模块103上时，无法直接将第一通孔10414与辅助针1052对齐，而且即使在安装时将第一通孔10414与辅助针1052对齐后，在后续运输、使用过程中，分析物检测装置104仍可能相对于平行滑块模块103发生旋转偏移，导致体内部分1042脱离辅助针1052的包络，影响使用。因此可根据卡孔10412与T型结构卡扣10352的对应关系，一方面可以确定分析物检测装置104在平行滑块模块103上的放置位置，另一方面可以防止分析物检测装置相对于平行滑块模块103发生旋转偏移，提升了使用体验。
在本发明实施例中，上外壳体10411与下外壳体10413的圆周尺寸一致，从而在上外壳体10411和下外壳体10413的结合处形成平滑的连接面，减小了因误碰导致上外壳体10411和下外壳体10413分离的可能性，可以保证分析物检测装置104的正常使用。
在本发明实施例中，在上外壳体10411的外侧设置有围绕上外壳体10411的环形槽，T型结构卡扣10352可以嵌入到环形槽中，以实现对分析物检测装置104的卡扣固定。T型结构卡扣10352脱离环形槽后，分析物检测装置104即可与平行滑块模块103分离。
在本发明其他实施例中，环形槽还可被设置在下外壳体10413的外侧，或者设置在上外壳体10411和下外壳体10413的连接处外侧。
结合参照图6b和图6c，在本发明其他实施例中，上外壳体10411与下外壳体10413的圆周尺寸不一致，优选的，上外壳体10411的直径略大于下外壳体10413的直径，例如，上外壳体10411的直径比下外壳体10413的直径大0.05～5mm，这样，上外壳体10411相对于下外壳体10413形成阶梯结构10415。当分析物检测装置104放置在平行滑块模块103上时，上外壳体10411贴合近端面1034，T型结构卡扣10352与阶梯结构10415贴合，形成卡扣连接，T型结构卡扣10352通过阶梯结构10415将分析物检测装置104压合在平行滑块模块103的近端面1034上。
在本发明一些实施例中，阶梯结构10415可以是由上外壳体10411骤变至下外壳体10413的台阶结构(如图6a所示)，当平行滑块模块位于远端时， 分析物检测装置104固定在平行滑块模块103上，T型结构卡扣10352接触上外壳体1411。但是在本发明实施例中，在分析物检测装置104安装至用户皮肤表面后，当用户在使用过程中，可能会触碰到台阶结构的外沿，导致上外壳体10411与下外壳体10413脱离，使得内部构件暴露，影响分析物检测装置104的使用可靠性。
针对上述台阶结构可能存在的问题，在本发明其他实施例中，阶梯结构10415还可以包括由上外壳体10411外沿连接至下外壳体10413外沿的倾斜过渡面，该倾斜过渡面可以是上外壳体10411的壳体延伸，也可以是下外壳体10413的壳体延伸，倾斜过渡面可以将上外壳体10411和下外壳体10413的外沿紧密连接起来，用户在使用过程中触碰到上外壳体10411和下外壳体10413的外沿时，不会导致上外壳体10411和下外壳体10413分离，提高了分析物检测装置的使用可靠性。当平行滑块模块位于远端时，分析物检测装置104固定在平行滑块模块103上，T型结构卡扣10352接触倾斜过渡面。
本领域技术人员可以理解的是，无论阶梯结构10415是台阶结构还是倾斜的过渡面，阶梯结构10415围绕在外壳1041外侧，为环形结构。
结合参照图5c，在本发明实施例中，通过阶梯结构10415与T型结构卡扣10352的配合可以使分析物检测装置104固定在平行滑块模块103上，但无法起到如前所述的定位作用，即无法防止分析物检测装置104发生旋转偏移，基于此，还需要在外壳1041上设置限位卡孔10416，对应的，在平行滑块模块103上设置有限位卡块1036，当分析物检测装置104放置在平行滑块模块103上时，限位卡块1036可以嵌入限位卡孔10416中，一方面可以使分析物检测装置104按照预定方向放置在平行滑块模块103上，另一方面可以防止分析物检测装置104发生旋转偏移，确保辅助针1052能穿过第一通孔10414或者自密封构件。
在本发明实施例中，限位卡块1036的数量至少为1个，本领域技术人员可以知晓的是，1个限位卡块1036以及1个对应的限位卡孔10416即能实现定位和防止旋转偏移的功能，但是可能会导致分析物检测装置104受力不均，因此可以优选地设置至少2个对应的限位卡块1036和限位卡孔10416，限位卡块1036和限位卡孔10416分别在平行滑块模块103和分析物检测装置104的圆周上均匀间隔分布。
在本发明优选实施例中，限位卡块1036与限位卡孔10416地数量均为2个，分别对称分布在平行滑块模块103和分析物检测装置104的圆周上。
在本发明实施例中，限位卡块1036设置在平行滑块模块103的内圈圆周上，限位卡孔10416设置在分析物检测装置104壳体的外圈圆周上。
在本发明其他实施例中，限位卡块1036设置在分析物检测装置104壳体的外圈圆周上，限位卡孔10416设置在平行滑块模块103的内圈圆周上。
参照图6d，图6显示的是分析物检测装置104的内部示意图。如前所述，分析物检测装置104内包含传感器1042的体内部分10421、导电胶条1042和内部电路1044，本领域技术人员可以理解的是，除了上述描述的构件外，分析物检测装置104还可以包含电池(图中未示出)、蜂鸣器(图中未示出)、LED灯(图中未示出)等构件。
在本发明实施例中，体内部分10421上设置有数个引脚，每个引脚通过设置在传感器1042的绝缘基底上的导线与体外部分10422的电极连接，用于接收来自于内部电路1044的电流，以及向内部电路1044传输包含分析物参数信息的检测电流。
在本发明一些实施例中，体内部分10421可以直接与内部电路1044上的电触点接触，但由于尺寸限制，体内部分10421上的引脚分布比较紧密，若直接与内部电路1044上的电触点接触，可能会导致某一些引脚接触到错误的电触点，从而导致短路或者电信号混乱。
参照图6e，在本发明一些实施例中，体内部分10421通过导电胶条1043与内部电路1044上的电触点接触，导电胶条1043由间隔分布的导电区和绝缘区构成，导电区和绝缘区分布在导电胶条1043表面，或者贯穿导电胶条1043。
在本发明一些实施例中，为了使体内部分10421与内部电路1044间形成良好的导电、绝缘连接，并且还要尽可能地利用分析物检测装置104的内部空间，可以对传感器1042、导电胶条1043和内部电路1044的相对位置和连接关系作一些调整和改进。
在本发明一些实施例中，传感器1042的体内部分10421可以相对于体外部分10422弯折或者弯曲，弯折或者弯曲传感器1042是为了更好地利用分析物检测装置104的内部空间，而不会影响其使用。
继续参照图6e，在本发明一些实施例中，导电胶条1043为长方体型，导电区和绝缘区沿其长度方向间隔分布，因此可以使用的导电接触面有4个，可以根据传感器1042和内部电路1044的实际放置位置和结构设计，灵活使用导电胶条1043的4个面。
在本发明其他实施例中，导电胶条1043还可以为圆柱体型、三棱柱形、圆球形、三棱锥形等规则形状，还可以是其他不规则形状。
继续参照图6d，并以图6d所示方向为参考。在本发明实施例中，内部电路1044放置在分析物检测装置104内部，导电胶条1043为长方体形，其上端面与内部电路1044的下端面接触，这样导电胶条1043还剩下左端面、右端面和下端面可供传感器1042的体外部分10421接触。在图6d中，体外部分10421与导电胶条1043的左端面接触，本领域技术人员可以知晓的是，体外部分10421还可以与导电胶条1043的下端面或者右端面接触，如图6g所示，同样可以有效实现传感器1042与内部电路1044间的电流传递。
为了简便理解内部电路1044、导电胶条1043和传感器1042间的电连接方式，以下仅围绕上述三个构件及连接方式进行说明。
参照图6f，在本发明一些实施例中，体外部分10421相对于体内部分10422弯折，体外部分10421与导电胶条1043的右端面接触，导电胶条1043的上端面与内部电路1044的下端面接触。
参照图6h，在本发明一些实施例中，斑马条1043的下端面与内部电路1044的上端面接触，体外部分10421与斑马条1043的右端面接触。在本发明另一些实施例中，体外部分10421相对于体内部分10422弯折或者弯曲，在这种结构下，体外部分10421可以与导电胶条1043的上端面接触，而不影响体内部分10422的位置与状态。
在本发明其他实施例中，分析物检测装置104不仅限于上述结构。在本发明另一些实施例中，发射器设置在外壳1041外，用户通过安装单元100将外壳1041安装到用户皮肤表面后，再将发射器安装到外壳1041上。
在本发明再一些实施例中，发射器与外壳1041分离时，电池内置于发射器。
在本发明再一些实施例中，发射器与外壳1041分离时，电池内置于外壳1041。
辅助针模块
图7a为本发明实施例辅助针模块的结构示意图。图7b为本发明实施例传感器弯曲示意图。图7c为本发明实施例安装前弹性垫套设在辅助针外侧的示意图。图7d为本发明实施例辅助针刺入皮下后弹性垫套设在辅助针外侧的示意图。图7e为本发明实施例辅助针缩回后弹性垫套设在传感器外侧的示意图。图7f为本发明实施例弹性垫为实心的结构示意图。图7g为本发明实施 例弹性垫为空心的结构示意图。图7h为本发明实施例弹性垫内嵌到分析物检测装置外壳的结构示意图。
参照图7a，在本发明实施例中，辅助针模块105包括辅助针固定结构1051和辅助针1052。在安装单元100中，辅助针固定结构1051位于远端，辅助针1052位于近端。
在本发明实施例中，辅助针固定结构1051包括辅助针滑块10511和辅助针固定块10512，辅助针滑块10511的直径或者宽度大于辅助针固定块10512的直径或者宽度，形成一个朝向近端的凸面10513。
在本发明实施例中，辅助针1052包括全包围针体10521和半包围针体10522，全包围针体10521位于辅助针固定块10512和半包围针体10522之间，并与辅助针固定块10512固定连接。半包围针体10522的中空结构可用于容纳传感器1042的体内部分，半包围针体10522刺入用户皮下时，可将体内部分一并刺入皮下，并且在针体缩回时，不影响体内部分在皮下的状态。
在本发明其他实施例中，辅助针1052仅包括半包围针体10522，即半包围针体10522与辅助针固定块10512固定连接，这样可以减少辅助针1052的用料，节省成本，但同时也减小了辅助针1052的刚性。
在安装单元100中，辅助针1052依次穿过第二通孔和第一通孔10414，从而贯穿分析物检测装置104，传感器1042的体内部分位于半包围针体10522中。
参考图7b，尽管在理想状态下，期望半包围针体10522能完全包络传感器的体内部分10422，但由于体内部分10422靠近辅助针1052的一侧上布置有电极(图中未示出)，导致体内部分10422的基底会向远离辅助针1052的一侧弯曲，形成如图7b所示状态。另外，本发明实施例中的安装单元100中的各零部件尺寸较小，虽能减轻重量、便于用户使用，但在安装过程中，由于各零部件尺寸配合的不一致、公差预留等原因，例如限位槽1013和T型结构滑块10351间、滑块卡扣10321与辅助针滑块10511卡扣间的配合不稳定，导致辅助针1052出现微弱的摇摆，半包围针体10522与传感器的体内部分10422无法处于有效的平行状态，体内部分10422可能会摆脱半包围针体10522的包络。基于上述原因，体内部分10422无法随半包围针体10522有效的刺入皮下，降低了分析物检测装置104的检测可靠性。
参照图7c，为了解决上述问题，在本发明一些实施例中，在安装前，半包围针体10522外侧套设一个弹性垫108，半包围针体10522包络住传感器 1042的体内部分10422，弹性垫108可以将体内部分10422束缚在半包围针体10522内，可以防止体内部分10422弯曲的同时，还可以在安装过程中，辅助针1052发生摇摆时，防止体内部分10422摆脱到半包围针体10522外，使得体内部分1422能随半包围针体10522顺利刺入皮下，提高了分析物检测装置104的检测可靠性。
在本发明优选实施例中，弹性垫108靠近半包围针体10522的针尖一端，可以更好地约束体内部分10422，防止体内部分10422脱离半包围针体10522的包络，或者弯曲。
参照图7d，在本发明一些实施例中，安装单元100在实施安装动作时，半包围针体10522携带体内部分10422刺入皮下，弹性垫108由于皮肤的阻挡而保持静止，因此半包围针体10522在刺入皮下的过程中，弹性垫108相对于半包围针体10522向远端滑动，直至分析物检测装置104的下外壳体10413接触皮肤表面，并且压住弹性垫108。
参照图7e，在本发明一些实施例中，半包围针体10522携带体内部分10422刺入皮下到预定位置后缩回，留下体内部分10422保持在皮下以检测分析物参数信息。分析物检测装置104在胶布的作用下粘在皮肤表面，因此在半包围针体10522缩回时，弹性垫108被下外壳体10413阻挡而保持静止，弹性垫108相对于半包围针体10522向近端滑动，直至半包围针体10522脱离弹性垫108。弹性垫108被夹在下外壳体10413和皮肤表面之间，半包围针体10522完全缩回后，弹性垫108在自身弹性作用下收缩套设在体内部分10422外侧，压住并覆盖半包围针体10522刺入皮下造成的创口，可以防止血液从创口溢出而污染分析物检测装置104，同时还可以防止外界异物污染创口，提高创口愈合速度。
参照图7f，在本发明一些实施例中，弹性垫108可以是实心结构，半包围针体10522刺穿弹性垫108后，弹性垫108套设在半包围针体10522外侧。
结合参照图7c和7g，在本发明一些实施例中，弹性垫108可以是空心结构，弹性垫108的内径d’小于半包围针体10522的外径d，使得弹性垫108可以紧密套设在半包围针体10522外侧，以阻止体内部分10422脱离半包围针体10522的包络。在本发明优选实施例中，弹性垫108的内径d’还小于体内部分10422的外径，在半包围针体10522缩回后，弹性垫108可以收缩并紧密套设在体内部分10422的外侧，以压住并覆盖半包围针体10522刺入皮下造成的创口。
在本发明一些实施例中，弹性垫108的厚度为0.01～5mm，弹性垫108过厚会增加分析物检测装置104对皮肤表面的压力，产生不适感，弹性垫108过薄自身容易产生形变，对体内部分10422无法形成有效的约束。在本发明优选实施例中，弹性垫108的厚度为0.3mm。
参照图7h，在本发明一些实施例中，第一通孔10414内沉到下外壳体10413内部，在安装过程中，弹性垫108被皮肤表面抵住，直至下外壳体10413被推进到与皮肤表面接触，弹性垫108嵌入到第一通孔10414内，并与下外壳体10413平齐，这样弹性垫108不会对皮肤表面造成额外的挤压，降低了不适感。
在本发明一些实施例中，弹性垫108的材质为橡胶、硅胶或者乳胶中的一种，具备良好弹性的同时，能避免对创口造成污染。
触发模块
图8为本发明实施例触发模块的结构示意图。
在本发明实施例中，触发模块106上设置有至少两个与第一卡扣1012对应的固定卡扣1061。在安装单元100中，固定卡扣1061与第一卡扣1012接触，以阻止第一卡扣1012向壳体外侧弯曲或者弯折。固定卡扣1061与第一卡扣1012的接触可以是点接触、线接触或者面接触，当接触为面接触时，固定卡扣1061与第一卡扣1012接触面与水平面呈固定夹角，并汇聚在安装单元100的近端。固定卡扣1061的数量及位置与第一卡扣1012一致。
在本发明实施例中，触发模块106上还设置有至少两个卡耳1062，在安装单元100中，卡耳1062与卡槽1014卡扣配合，以固定触发模块106。卡耳1062的数量及位置与卡槽1014一致。结合参照图10a，在安装单元100使用前，卡耳1062位于第一卡槽位10141，此时，固定卡扣1061与第一卡扣1012接触。
在本发明实施例中，触发模块106还包括一个外圈1063，外圈1063将上述固定卡扣1061和卡耳1062连接成一个整体。在安装单元100中，外圈1063相对于卡耳1062靠近于近端，位于第一开口且凸出于第一开口，在使用安装单元100时，外圈1063贴合用户皮肤表面。
弹性模块
参照图3，弹性模块107包括第一弹性件1071和第二弹性件1072。
在本发明实施例中，第一弹性件1071位于平行滑块模块103和壳体101之间，即第一弹性件1071的一端位于平行滑块模块103的远端面，另一端位 于壳体101内，在安装单元100中，第一弹性件1071处于压缩状态，可提供弹力。
在本发明实施例中，第二弹性件1072位于平行滑块模块103和辅助针模块105之间，即第二弹性件1072的一端位于平行滑块模块103的凸台10322上，另一端位于辅助针模块105的凸面10513上，在安装单元100中，第二弹性件1072处于压缩状态，可提供弹力。
在本发明优选实施例中，第一弹性件1071或者第二弹性件1072为金属弹簧。
在本发明实施例中，第一弹性件1071的内圈直径大于圆形槽1032和辅助针滑块10511的外圈直径，在安装单元100中，第一弹性件1071包围在辅助针滑块10511和圆形槽1032外侧，可以充分利用安装单元100的内部空间。
在本发明实施例中，第二弹性件1072的外圈直径大于辅助针固定块10512的外径和凸台10322的内径，而小于辅助针滑块10511的外径和圆形槽1032的内径，因此第二弹性件1072的一端放置在圆形槽1032内，另一端包围在辅助针固定块10512外侧，可以充分利用安装单元100的内部空间。
安装单元使用方法
图9为本发明实施例安装单元的俯视图。
图10a为图9的A剖面结构示意图；图10b为图9的B剖面结构示意图；图10c为图9的C剖面结构示意图；图11为第一卡扣受力弯折示意图。
结合参照图10a和图10b，在本发明实施例中，卡槽1014设置有两个卡槽位，第一卡槽位10141和第二卡槽位10142。在安装单元100使用前，触发模块106通过卡耳1062与第一卡槽位10141的卡扣配合固定在壳体101上，此时，固定卡扣1061与第一卡扣1012接触，阻止第一卡扣1012向壳体101外侧弯曲或者弯折，固定卡扣1061、第一卡扣1012和第二卡扣1033位于同一水平线上。在本发明优选实施例中，由壳体101内向外，依次为第二卡扣1033、第一卡扣1012和固定卡扣1061。
在本发明实施例中，固定卡扣1061与第一卡扣1012的接触为点接触、线接触或者面接触中的一种，当上述接触为面接触时，接触面的延长线m1汇聚在近端，这种结构设计可以使得固定卡扣1061相对于第一卡扣1012向远端运动。
在本发明优选实施例中，第二卡扣1033与第一卡扣1012的耦合面为平面，该平面与水平面呈固定夹角，其延长端m2汇聚在近端。
结合参照图11，这种结构设计可以使得第二卡扣1033相对于第一卡扣1012向近端运动时，将第一卡扣1012向壳体101外侧推开，从而解除第一卡扣1012与第二卡扣1033间的耦合状态。
在本发明实施例中，第一弹性件1071处于压缩状态，具备弹性势能，其自身弹力给予平行模块滑块103向近端的推力Fr，该推力Fr通过第二卡扣1033和第一卡扣1012的耦合面作用在第一卡扣1012上，并产生垂直于第一卡扣1012平面的分力Fsin，该分力Fsin可将第一卡扣1012向壳体101外侧推动而弯曲或者弯折，从而解除第一卡扣1012与第二卡扣1033的耦合状态。
在本发明实施例中，使用安装单元100时，旋转外盖体1021，使立柱10211折断，保护盖102与壳体101分离，将安装单元100的近端靠近用户皮肤，直到触发模块106的外圈1063贴合在皮肤表面，用户在远端按压壳体101，壳体101朝向皮肤运动，触发模块106保持不动，因此触发模块106相对于壳体101向远端运动，卡耳1062脱离第一卡槽位10141，进入到第二卡槽位10142，同时固定卡扣1061不再与第一卡扣1012接触，第一卡扣1012因分力Fsin向壳体101外侧弯曲或者弯折，第一卡扣1012与第二卡扣1033的耦合状态解除。
在本发明实施例中，解除耦合状态后，平行滑块模块103在第一弹性件1071的弹力推动下继续向近端运动，同时带动分析物检测装置104向近端运动，直至分析物检测装置104的下外壳体10413与用户皮肤表面接触。
参照图10c，在本发明实施例中，滑块卡扣10321与辅助针滑块10511卡扣连接，第一弹性件1071推动平行滑块模块103向近端运动时，带动辅助针模块105一起向近端运动。
在本发明实施例中，滑块卡扣10321与辅助针滑块10511的连接处为平面或者近似平面，该平面与水平面呈固定夹角，其延长线m3汇聚在远端。第二弹性件1072对辅助针滑块10511的推力朝向远端，因此辅助针滑块10511可将滑块卡扣10321向壳体101外侧推开，而使得滑块卡扣10321发生弯曲或者弯折，其原理等同于图11。
在本发明实施例中，在安装单元100中，辅助针限位槽1015的侧壁阻止滑块卡扣10321发生弯折或者弯曲，滑块卡扣10321与辅助针滑块10511卡扣连接状态不发生变化。随着平行滑块模块103和辅助针模块105向近端运动，直到滑块卡扣10321脱离辅助针限位槽1015，辅助针限位槽1015的内壁不再阻止滑块卡扣10321发生弯折或者弯曲，第二弹性件1072向远端推动 辅助针滑块10511，同时辅助针滑块10511推动滑块卡扣10321向外侧弯折或者弯曲，滑块卡扣10321与辅助针滑块10511的卡扣连接解除，第二弹性件1072继续推动辅助针滑块10511向远端运动，最终辅助针模块105回到初始位置，辅助针1052缩回到壳体101内，防止辅助针1052暴露在壳体101外面，避免造成不必要的伤害。
在本发明实施例中，滑块卡扣10321脱离辅助针限位槽1015时，辅助针的半包围针体10522刺入用户皮下。
在本发明实施例中，在安装单元100中，T型结构滑块10351位于限位槽1013内，限位槽1013通过T型结构滑块10351对平行滑块模块103的位置、方向进行限制，以保证平行滑块模块103与其滑动方向保持垂直，从而使设置在平行滑块模块103前端的分析物检测装置104与其运动方向保持垂直，同时辅助针1052与其运动方向保持平行，这样可以使辅助针1052及其包络的传感器体内部分以垂直角度刺入用户皮下，减轻用户的疼痛感。
在本发明实施例中，在平行滑块模块103向近端滑动过程中，T型结构滑块10351在限位槽1013内滑动，直至接触到触发模块106的外圈1063，在第一弹性件1071的推动下，平行滑块模块103继续向近端运动，而外圈1063阻挡T型结构滑块10351继续向近端运动，因此T型结构滑块10351绕竖直部弯曲或者弯折，T型结构卡扣10352与卡孔10412或者环形结构的卡扣连接解除，分析物检测装置104脱离平行滑块模块103，从而可以安装在用户皮肤表面。
在本发明实施例中，T型结构滑块10351与外圈1063接触时，平行滑块模块103所处的位置为预定位置，此时，分析物检测装置的下外壳体10413与用户皮肤表面接触。
在本发明实施例中，辅助针1052依次穿过第二通孔和第一通孔10414，而贯穿分析物检测装置104，同时，辅助针的半包围针体10522包络传感器1042。在平行滑块模块103和辅助针模块105向近端运动过程中，半包围针体10522携带传感器1042刺入皮下，辅助针1052缩回后，传感器1042体内部分保持在皮下，针体缩回时不影响传感器1042体内部分所处状态。
在本发明实施例中，实施安装动作时，需要用户在远端按压壳体101，向壳体101施加向近端的力F，触发模块106的外圈1063接触用户皮肤表面，用户皮肤给予外圈1063与力F反向的力F’，从而实现触发模块106与壳体101的相对运动。在实际安装过程中，触发模块106的绝对位置保持不变， 壳体101向近端运动。
在实施安装动作之前，为防止触发模块106相对于壳体101发生运动，在壳体101的近端安装保护盖102，保护盖102包围在触发模块的外圈1063外侧，可以防止因误碰外圈1063而在不正确的位置实施安装动作，起到防触发的作用。
内盖体1023的远端面10232与分析物检测装置104接触，同时辅助针1052和传感器1042伸入到内盖体凹槽10233，可以起到密封的作用，防止外界灰尘、颗粒等脏污与针体和传感器接触，造成污染。
在本发明实施例中，分析物检测装置的下外壳体10413上还设置有胶布(图中未示出)，用于将分析物检测装置104固定在用户皮肤表面。
综上所述，本发明实施例公开了一种分析物检测装置的安装单元，平行滑块模块的卡扣结构与分析物检测装置的环形结构接触，使平行滑块模块与分析物检测装置间形成可释放连接，在平行滑块模块位于远端时，分析物检测装置固定在平行滑块模块上，在平行滑块模块滑向近端后，分析物检测装置自动与平行滑块模块分离，安装单元结构简单，可靠性高，使用方便。
虽然已经通过示例对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
