Description

植入装置
本发明要求于2022年10月24日提交中国专利局、申请号为202222801795.9、申请名称为“植入装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及传感器植入技术领域，尤其涉及一种植入装置。
背景技术
连续血糖监测(Continuous Glucose Monitoring，CGM)，是通过葡萄糖感应器监测皮下组织的葡萄糖浓度，而间接反映血糖水平。现有的CGM测量仪内具有一用于植入传感器的硬针，在植入过程中，该硬针暴露在视野内，即可以被用户明显看到，增加了用户的心里负担。
发明内容
本申请的目的在于提供一种植入装置，以解决上述现有技术中CGM测量仪的硬针在植入操作过程中会暴露在视野内而增加用户心里负担的问题。
本申请提供了一种植入装置，其中，包括：
第一壳体，所述第一壳体内设置有植入组件；
第二壳体，所述第二壳体活动穿设于所述第一壳体，所述第一壳体设置有用于所述植入组件穿过的通孔；
门板组件，可移动地连接于所述第二壳体，用于封闭或打开所述通孔。
本申请提供的植入装置，通过活动的门板组件，可以在用户按压第二壳体前及按压壳体过程中均不会看到植入组件，从而可以避免用户对硬针等结构产生心里负担。
在一种可能的设计中，所述门板组件包括门板和第一弹性件，所述第一弹性件的一端连接于所述第二壳体，所述第一弹性件的另一端连接于所述门板，所述门板在封闭所述通孔的状态下，所述第一弹性件处于压缩状态。
其中，在按压第二壳体时，第二壳体相对于第一壳体运动，可以解除门板对通孔的封闭状态，第一弹性件在恢复变形的过程中释放弹性势能，能够拉动门板相对于第二壳体运动，使其解除对通孔的遮挡，从而实现了在按压第二壳体时门板组件的自动打开。
在一种可能的设计中，所述门板对称设置有两个，每个所述门板分别通过至少一个所述第一弹性件连接于所述第二壳体，两个所述门板分别通过所述第一弹性件反向运动。
其中，在通孔封闭状态下，两个门板相互对合，且对合的位置可以位于通孔的对称中心，从而使两个门板在运动打开时能够具有相同的运动行程和运动时间。具体地，在两个门板打开时，与两个门板对应连接的第一弹性件可以使两个门板反向运动，从而使两个门板均运动了通孔尺寸的一半，即可实现通孔完全打开，在门板完全打开后，植入组件尚未到达通孔处，从而能够避免植入组件与门板干涉。
在一种可能的设计中，每个所述门板分别通过两个所述第一弹性件连接于所述第二壳体，沿垂直于所述门板的运动方向，与一个门板相连的两个第一弹性件对称分布。
通过使每个门板连接两个第一弹性件，可以使每个门板获得更大的驱动力，提升门板打开速度，且每个门板连接的两个第一弹性件对称分布，能够对门板施加较均匀的驱动力，保证门板运动的稳定性，有利于门板的快速打开。
在一种可能的设计中，所述门板组件还包括导向结构，所述导向结构连接于所述第二壳体，所述门板与所述导向结构滑动连接。通过使门板与导向结构滑动连接，可以保证门板运动的稳定性，有利于门板快速打开。
在一种可能的设计中，所述导向结构为滑轨。
在一种可能的设计中，所述植入装置还包括限位组件，所述限位组件连接于所述第二壳体，用于限制所述门板组件保持对所述通孔的封闭状态。当门板组件封闭通孔时，该限位组件可以与门板组件配合， 防止门板组件打开，从而可以在该植入装置未使用时，通过门板组件与限位组件的配合保持通孔封闭。
在一种可能的设计中，所述限位组件包括杠杆和第二弹性件，所述杠杆包括第一端和第二端，所述杠杆上位于所述第一端和所述第二端之间的部位设置有转动部，所述转动部与所述第二壳体转动连接；所述第二弹性件的一端连接于所述第二壳体，所述第二弹性件的另一端连接于所述杠杆的第一端，所述杠杆的第一端背离所述第二弹性件的一端用于限制所述门板组件保持对所述通孔的封闭状态；所述第一壳体的内侧壁设置有第一凸起，所述杠杆的第二端的至少部分与所述第一凸起挡接。
当按压第二壳体时，第二壳体相对于第一壳体向下运动，杠杆随第二壳体同步向下运动，由于第二端的至少部分与第一凸起挡接，第二端在经过第一凸起时，会被第一凸起向第一壳体的内部推动，使杠杆的转动部相对于第二壳体转动，而杠杆的第一端则会向远离门板组件的方向运动，从而可以使第一端与门板组件分离，门板组件失去杠杆的约束后，可以通过第一弹性件的作用使门板自动打开。其中，第一凸起朝向第二壳体的一面可以为斜面，从而在杠杆向下运动时，能够通过第一凸起的斜面的导向滑动经过第一凸起，避免杠杆在第一凸起处发生卡滞。
在一种可能的设计中，所述杠杆的第一端设置有卡爪，所述门板组件设置有卡槽，所述卡爪与所述卡槽卡接配合。在门板组件封闭通孔时，杠杆的卡爪可以卡设至卡槽中，从而可以防止门板组件打开。而在下压第二壳体时，杠杆的转动可以使卡爪与卡槽分离，失去了卡爪约束的门板组件可以自动打开。
在一种可能的设计中，所述限位组件包括按钮和第三弹性件，所述按钮与所述第二壳体滑动连接，且所述按钮部分凸出于所述第二壳体上表面，所述按钮设置有限位部，所述限位部用于限制所述门板组件保持对所述通孔的封闭状态；所述第三弹性件的一端与所述按钮连接，所述第三弹性件的另一端与所述第二壳体连接。
在用户按压第二壳体时，由于按钮凸出于第二壳体的上表面，用户会优先按压在按钮上，按钮先于第二壳体向下运动，使按钮的限位部与门板组件分离，门板组件失去限位部的约束后，可以自动打开，而在门板组件失去限位部约束的时，用户皮肤可以与第二壳体的上表面接触，并覆盖通孔，从而在门板组件打开过程中，由于通孔被皮肤遮挡，用户不能通过通孔看到内部的植入组件，从而减轻心里负担。
在一种可能的设计中，所述限位部包括卡爪，所述门板组件设置有卡槽，所述卡爪与所述卡槽卡接配合。在门板组件封闭通孔时，卡爪可以卡设至卡槽中，从而可以防止门板组件打开。而在下压按钮时，可以使卡爪与卡槽分离，失去了卡爪约束的门板组件可以自动打开。
在一种可能的设计中，所述限位组件还包括支撑件，所述支撑件固定于所述第二壳体，所述支撑件与所述按钮相对的部位与所述第二壳体之间设置有用于所述按钮移动的活动空间，所述第三弹性件远离所述按钮的一端连接于所述支撑件。
其中，该支撑件可以保证对按钮及第三弹性件可靠的支撑。其中，通过使支撑件与第二壳体之间设置上述活动空间，可以便于按钮在受压后能够运动至第二壳体中，以使按钮的限位部能够与门板组件分离，解除对门板组件的约束，使门板组件能够自动打开。
在一种可能的设计中，所述第二壳体的底部设置有支撑部，所述第一壳体的内壁设置有第二凸起，沿所述第二壳体的运动方向，所述支撑部的至少部分搭接于所述第二凸起。
其中，在该植入装置未使用时，第二壳体可以通过支撑部支撑在第一壳体的第二凸起上，防止第二壳体落入第一壳体内；而在通过适当的外力按压第二壳体时，支撑部受力后可以发生适当的弹性变形，一方面可以吸收第二壳体受到的力，实现对第二壳体运动的缓冲，防止第二壳体受力较大时快速落下，给用户带来不适感，另一方面可以通过弹性变形而发生偏移，以解除与第二凸起的搭接状态，使支撑部能够随第二壳体的运动经过第二凸起，使第二壳体能够顺利落入至第一壳体内，使植入组件能够从通孔伸出后完成植入动作。
应当理解的是，以上的一般描述和后文的细节描述仅是示例性的，并不能限制本申请。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在本申请的描述中，除非另有明确的规定和限定，术语“第一”、“第二”仅用于描述的目的，而不能理解为指示或暗示相对重要性；除非另有规定或说明，术语“多个”是指两个或两个以上；术语“连接”、“固定”等均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接，或电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
本说明书的描述中，需要理解的是，本申请实施例所描述的“上”、“下”等方位词是以附图所示的角度来进行描述的，不应理解为对本申请实施例的限定。此外，在上下文中，还需要理解的是，当提到一个元件连接在另一个元件“上”或者“下”时，其不仅能够直接连接在另一个元件“上”或者“下”，也可以通过中间元件间接连接在另一个元件“上”或者“下”。
连续血糖监测(Continuous Glucose Monitoring，CGM)，是通过葡萄糖感应器监测皮下组织的葡萄糖浓度，而间接反映血糖水平。现有的CGM测量仪内具有一用于植入传感器的硬针，在不使用状态下，CGM测量仪的盖子可以将硬针遮蔽在测量仪内部，防止进入灰尘杂质等；而在使用时，需要将盖子取下，使该硬针露出，以便于通过硬针的辅助将传感器植入皮肤，而在植入的过程中，该硬针始终暴露在视野内，即可以被用户明显看到，这增加了用户的心里负担。
本实施例提供了一种植入装置，该植入装置可以应用在CGM测量仪等需要辅助植入的产品上。为了便于说明，本实施例以该植入装置应用在CGM测量仪上为例进行说明。
图1为本申请实施例提供的植入装置的结构示意图(门板组件关闭状态)，图2为本申请实施例提供的植入装置的结构示意图(门板组件打开状态)，如图1和图2所示，该植入装置包括第一壳体1、第二壳体2和门板组件3，第一壳体1内设置有植入组件，第二壳体2活动穿设于第一壳体1，第一壳体1设置有用于植入组件穿过的通孔21。门板组件3可移动地连接于第二壳体2，用于封闭或打开通孔21。
其中，该植入组件可以包括硬针、血糖发射器及血糖传感器等，血糖传感器较柔软，血糖传感器难以独立植入至皮肤中，因此需要通过硬度较大的硬针来辅助血糖传感器植入至皮肤中。例如，如图1和图2所示，当需要对手臂皮肤进行植入时，手臂上需要植入的部位可以对准第二壳体2上的通孔21处，然后持续按压第二壳体2，使第二壳体2向第一壳体1的内部移动，由于在植入过程中，第一壳体1内的植入组件相对于第一壳体1保持静止，也就是说，第二壳体2在向第一壳体1内运动时，第二壳体2与植入组件产生相对运动，即当第二壳体2运动至一定形成后，如图3所示，植入组件可以从通孔21中穿出，使硬针刺入手臂皮肤中，实现对血糖传感器的植入，同时，血糖发射器接触到皮肤后，可以通过发射器表面的双面胶粘贴在皮肤上，如图4所示；当第二壳体2运动到底后，可以触发第一壳体1内的退针机构，退针机构可以将硬针从人体内拔出，从而完成了全部的植入操作。
其中，如果通孔21在手臂按压第二壳体2之前即为打开状态，植入组件会通过通孔21暴露在用户的视野内，即用户可以明显地看到硬针，这会对用户造成较大的心里负担。为此，如图1所示，本实施例在通孔21处设置门板组件3，使门板组件3可移动地连接于第二壳体2，即门板组件3通过相对于第二壳体2的移动，可以实现在用户未按压第二壳体2时，使通孔21保持封闭状态，防止用户按压第二壳体2前看到植入组件；如图2所示，在用户按压第二壳体2时，门板组件3可以自动打开，使植入组件能够从通孔21中穿出，此时，由于需要保持按压第二壳体2，用户的手臂等需要植入的部位会将通孔21覆盖，不会看到通孔21及内部的植入组件。由此，通过活动的门板组件3，可以在用户按压第二壳体2前及按压壳体过程中均不会看到植入组件，从而可以避免用户对硬针等结构产生心里负担。
其中，第一壳体1和第二壳体2可以为筒状结构，例如圆柱形筒状、椭圆柱形筒状、棱柱形筒状等，第一壳体1的高度高于第二壳体2的高度，从而可以使第二壳体2能够运动至第一壳体1内，以便于第一壳体1内的植入组件能够从第二壳体2的通孔21中穿出。其中，如图2所示，第二壳体2的顶部设置有盖板24，通孔21可以开设在盖板24上，在植入过程中，用户的皮肤组织可以按压第二壳体2的盖板24，从而可以通过盖板24使用户的皮肤与第二壳体2之间具有较大的接触面积，提升用户按压第二壳体2的舒适度，同时能够保证第二壳体2在受压运动时的稳定。
具体地，门板组件3包括门板31和第一弹性件32，第一弹性件32的一端连接于第二壳体2，第一弹性件32的另一端连接于门板31，门板31在封闭通孔21的状态下，第一弹性件32处于压缩状态。
如图1和图5所示，该门板31可以为平板状结构，在该植入装置未使用状态下，门板31能够将通孔21封闭，无法通过通孔21看到植入装置内部的植入组件，此时的第一弹性件32处于压缩状态。如图2和图6所示，在使用中按压第二壳体2时，第二壳体2相对于第一壳体1运动，可以解除门板31对通孔21的封闭状态，第一弹性件32在恢复变形的过程中释放弹性势能，能够拉动门板31相对于第二壳体2运动，使其解除对通孔21的遮挡，从而实现了在按压第二壳体2时门板组件3的自动打开。由此，通过门板31和第一弹性件32的配合，可以在按压第二壳体2时能够实现门板31的自动打开，也就是说，在皮肤封闭通孔21并按压第二壳体2时，用户不会看到植入组件，同时，门板31自动打开后，能够实现植入组件从通孔21中穿出，不会对植入组件造成干涉，用户只需要对第二壳体2进行按压即可完成植入操作，既方便了该植入装置的使用，又可以防止用户看到植入组件而产生心里负担。
其中，门板31可以设置于第二壳体2的盖板24下方，即盖板24朝向第一壳体1的一侧，从而可以使该植入装置的外观干净简洁，同时可以对门板31、第一弹性件32等活动部件进行保护，防止磕碰或污染。此外，为了便于第一弹性件32的组装，该第一弹性件32可以为弹簧、弹片等。
具体地，门板31可以设置有一个，第一弹性件32也可以相应设置有一个，从而可以使零部件使用较少，结构简单。但是，当门板31从封闭状态到完全打开状态，需要运动较大的行程，且第一弹性件32也需要较大的力以保证将门板31从通孔21的一端拉动至另一端，这会导致门板31完全打开需要较长的时间，容易发生门板31未完全打开，植入组件却到达通孔21处，而造成植入组件与门板31干涉的问题。
本实施例中，如图5和图6所示，门板31对称设置有两个，每个门板31分别通过至少一个第一弹性件32连接于第二壳体2，两个门板31分别通过对应的第一弹性件32反向运动。也就是说，在通孔21封闭状态下，两个门板31相互对合，且对合的位置可以位于通孔21的对称中心，从而使两个门板31在运动打开时能够具有相同的运动行程和运动时间。具体地，在两个门板31打开时，与两个门板31对应连接的第一弹性件32可以使两个门板31反向运动，从而使两个门板31均运动了通孔21尺寸的一半，即可实现通孔21完全打开，在门板31完全打开后，植入组件尚未到达通孔21处，从而能够避免植入组件与门板31干涉。
具体地，每个门板31分别通过两个第一弹性件32连接于第二壳体2，沿垂直于门板31的运动方向，与一个门板31相连的两个第一弹性件32对称分布。
其中，对于门板组件3包括两个门板31的结构而言，每个门板31连接一个第一弹性件32时，虽然可以实现门板31的打开，但一个第一弹性件32的驱动力有限，且难以保证门板31在运动方向上受力均匀，门板31因受力不均而产生晃动，易在运动中发生卡滞。为此，本实施例中，如图7和图8所示，通过使每个门板31连接两个第一弹性件32，可以使每个门板31获得更大的驱动力，提升门板31打开速度，且每个门板31连接的两个第一弹性件32对称分布，能够对门板31施加较均匀的驱动力，保证门板31运动的稳定性，有利于门板31的快速打开。
具体地，如图5和图6所示，门板组件3还包括导向结构33，导向结构33连接于第二壳体2，门板31与导向结构33滑动连接。通过使门板31与导向结构33滑动连接，可以保证门板31运动的稳定性，有利于门板31快速打开。
该导向结构33可以设置于第二壳体2的盖板24的内侧，使该导向结构33可以受到盖板24的遮蔽，以防止受到外界粉尘杂质等污染。
具体地，该导向结构33可以为滑轨，该滑轨可以通过螺钉、铆钉等连接件固定于第二壳体2，从而可以便于安装固定。
在其他实施例中，该导向结构33也可以为形成于第二壳体2上的滑槽，门板31的边缘可以滑动设置于滑槽中，或者在第二壳体2上形成有导向凸棱，门板31上可以设置有能够与导向凸棱滑动连接的槽。
具体地，如图9所示，植入装置还包括限位组件4，限位组件4连接于第二壳体2，用于限制门板组件3保持对通孔21的封闭状态。当门板组件3封闭通孔21时，该限位组件4可以与门板组件3配合，防止门板组件3打开，从而可以在该植入装置未使用时，通过门板组件3与限位组件4的配合保持通孔 21封闭。
具体地，在一种实施例中，如图9至图11所示，限位组件4包括杠杆41和第二弹性件，杠杆41包括第一端411和第二端412，杠杆41上位于第一端411和第二端412之间的部位设置有转动部413，转动部413与第二壳体2转动连接；第二弹性件的一端连接于第二壳体2，第二弹性件的另一端连接于杠杆41的第一端411，杠杆41的第一端411背离第二弹性件的一端用于限制门板组件3保持对通孔21的封闭状态；第一壳体1的内侧壁设置有第一凸起11，的杠杆41的第二端412的至少部分与第一凸起11挡接。
其中，如图11所示，杠杆41为一种杆状结构，其两端分别形成为第一端411和第二端412。第二壳体2的内壁可以设置有连接块22，该连接块22能够向第二壳体2的内部凸出，以便于与杠杆41转动连接，具体地，杠杆41可以通过轴状结构的转动部413与连接块22转动连接。
如图9和图10所示，在该植入装置未使用状态下，该杠杆41可以保持竖直的状态，其第一端411可以通过第二弹性件提供的作用力与门板组件3限位配合，以使门板组件3保持地通孔21的封闭状态，杠杆41的第二端412在竖直方向上可以与第一凸起11挡接，即第二端412在竖直方向上的投影至少部分与第一凸起11重合，此时，第二端412与第一凸起11可以接触也可以不接触，第二端412与第一凸起11之间可以不存在相互作用力。当按压第二壳体2时，第二壳体2相对于第一壳体1向下运动，杠杆41随第二壳体2同步向下运动，由于第二端412的至少部分与第一凸起11挡接，第二端412在经过第一凸起11时，会被第一凸起11向第一壳体1的内部推动，使杠杆41的转动部413相对于第二壳体2转动，而杠杆41的第一端411则会向远离门板组件3的方向运动，从而可以使第一端411与门板组件3分离，门板组件3失去杠杆41的约束后，可以通过第一弹性件32的作用使门板31自动打开。其中，第一凸起11朝向第二壳体2的一面可以为斜面，从而在杠杆41向下运动时，能够通过第一凸起11的斜面的导向滑动经过第一凸起11，避免杠杆41在第一凸起11处发生卡滞。
其中，第二弹性件可以为弹簧或弹片等，当然也可以为具有弹性的橡胶、硅胶等。
具体地，如图11所示，杠杆41的第一端411设置有卡爪43，门板组件3设置有卡槽34，卡爪43与卡槽34卡接配合。在门板组件3封闭通孔21时，杠杆41的卡爪43可以卡设至卡槽34中，从而可以防止门板组件3打开。而在下压第二壳体2时，杠杆41的转动可以使卡爪43与卡槽34分离，失去了卡爪43约束的门板组件3可以自动打开。
当门板组件3包括两个门板31时，卡爪43可以具有两个，每个门板31上均可以设置有一个卡槽34，两个卡爪43能够分别与两个门板31的卡槽34卡接配合，实现对两个门板31的限位
在另一种实施例中，如图12至图16所示，限位组件4包括按钮44和第三弹性件45，按钮44与第二壳体2滑动连接，且按钮44部分凸出于第二壳体2上表面，按钮44设置有限位部441，限位部441用于限制门板组件3保持对通孔21的封闭状态；第三弹性件45的一端与按钮44连接，第三弹性件45的另一端与第二壳体2连接。
可以理解的是，为了便于按钮44能够相对于第二壳体2滑动，第二壳体2上可以设置有孔，按钮44可以在孔中滑动，且按钮44上至少部分能够从孔中伸出，以便于按压。具体地，如图15和图16所示，在用户按压第二壳体2时，由于按钮44凸出于第二壳体2的上表面，用户会优先按压在按钮44上，按钮44先于第二壳体2向下运动，使按钮44的限位部441与门板组件3分离，门板组件3失去限位部441的约束后，可以自动打开，而在门板组件3失去限位部441约束的时，用户皮肤可以与第二壳体2的上表面接触，并覆盖通孔21，从而在门板组件3打开过程中，由于通孔21被皮肤遮挡，用户不能通过通孔21看到内部的植入组件，从而减轻心里负担。
其中，第三弹性件45可以实现对按钮44的支撑，使该植入装置在未使用的状态下，按钮44能够存在部分部位凸出于第二壳体2的上表面，而在按压第二壳体2时，第三弹性件45可以被压缩，使按钮44可以被按压到第二壳体2中。其中，第三弹性件45可以为弹簧或弹片等，当然也可以为具有弹性的橡胶、硅胶等。
具体地，如图14所示，限位部441包括卡爪43，门板组件3设置有卡槽34，卡爪43与卡槽34卡接配合。在门板组件3封闭通孔21时，卡爪43可以卡设至卡槽34中，从而可以防止门板组件3打开。而在下压按钮44时，可以使卡爪43与卡槽34分离，失去了卡爪43约束的门板组件3可以自动打开。
具体地，如图13中图16所示，限位组件4还包括支撑件46，支撑件46固定于第二壳体2，支撑 件46与按钮44相对的部位与第二壳体2之间设置有用于按钮44移动的活动空间47，第三弹性件45远离按钮44的一端连接于支撑件46。
该支撑件46可以为塑料件，也可以为金属件，当然也可以为具有一定硬度的其它结构，该支撑件46可以通过螺钉48与第二壳体2固定连接，以保证对按钮44及第三弹性件45可靠的支撑。其中，通过使支撑件46与第二壳体2之间设置上述活动空间47，可以便于按钮44在受压后能够运动至第二壳体2中，以使按钮44的限位部441能够与门板组件3分离，解除对门板组件3的约束，使门板组件3能够自动打开。
本实施例中的按钮44、第三弹性件45及支撑件46的配合，可以占用较小的空间即可实现对门板组件3的限位或解除限位，结构小巧简单，便于操作。其中，通孔21从关闭到打开的状态也可以通过上述门板31和第一弹性件32的配合来实现，如图17和图18所示，在次不再赘述。
具体地，如图19所示，第二壳体2的底部设置有支撑部23，第一壳体1的内壁设置有第二凸起12，沿第二壳体2的运动方向，支撑部23的至少部分搭接于第二凸起12。
在该植入装置未使用时，第二壳体2可以通过支撑部23支撑在第一壳体1的第二凸起12上，防止第二壳体2落入第一壳体1内；而在通过适当的外力按压第二壳体2时，支撑部23受力后可以发生适当的弹性变形，一方面可以吸收第二壳体2受到的力，实现对第二壳体2运动的缓冲，防止第二壳体2受力较大时快速落下，给用户带来不适感，另一方面可以通过弹性变形而发生偏移，以解除与第二凸起12的搭接状态，使支撑部23能够随第二壳体2的运动经过第二凸起12，使第二壳体2能够顺利落入至第一壳体1内，使植入组件能够从通孔21伸出后完成植入动作。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
