具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
参照图1与图2，本发明的优选实施例提供了一种贴敷式胰岛素泵，包括外壳，外壳内设 有空腔以便于容纳与安装各零部件，外壳内设有注射组件，注射组件包括储液组件20与针管组件，储液组件20用于为患者的注射储存并提供药液，储液组件20的一端连接泵液组件，储液组件20的另一端连接针管组件，泵液组件能够将储液组件20内的药液输送至针管组件中并通过针管组件将药液最终注入患者体内进行治疗，外壳内设有控制主板组件50用于控制泵液组件的关闭与具体运行过程，外壳内还可设有为泵液组件、控制主板组件50提供能源的能源组件60。
参照图1，外壳包括前盖11与后盖12，前盖11与后盖12能够共同组成一个容纳与安装零部件的腔体，前盖11与后盖12的结合处可设置防水胶圈以起到良好的防水效果。
参照图3，所述储液组件20包括用于盛装药液的储液筒21与配合安装在储液筒21内的活塞(未图示)，活塞在储液筒21内移动时能够将其内的药液向针管组件内推出。
参照图1、图3，泵液组件包括电磁驱动组件30与执行组件22，执行组件22的一端与电磁驱动组件30相连，执行组件22的另一端与储液筒21内的活塞相连，工作状态时，电磁驱动组件30为执行组件22提供动力使得执行组件22与活塞相连的一端推动活塞从而将药液通过针管组件注入患者体内进行治疗，电磁驱动组件30包括安装盒31以及电磁线圈组件，所述安装盒31用于对电磁线圈组件进行容纳，所述电磁线圈组件包括电磁线圈、磁铁以及支架，磁铁包括两异性磁铁，两个异性磁铁分别设于安装盒内的两端，电磁线圈固定在安装盒31内，支架位于电磁线圈的顶部，支架32上设有卡扣33，卡扣33用于连接执行组件22的一端，工作时，电磁线圈通电从而通过支架32与卡扣33给执行组件22提供驱动力，进而使得执行组件22通过活塞推动药液，该种电磁驱动的方式相对于现有技术中采用昂贵的电机驱动不仅有效的节省了使用成本，同时也便于本装置的整体小型化，由于电磁驱动的胰岛素泵体积小、便于隐藏，不易被发现可以避免正常人群异样的目光，同时胰岛素泵体积小型化后能够供患者选择注射的部位更多，例如腹部和四肢等位置，且该种胰岛素泵成本较低，使得患病人群能够支付得起相应的价格，因此使得胰岛素泵不仅能够在1型糖尿病人群中使用，而且能够扩大到2型糖尿病和妊娠糖尿病人群，具有更高的普适性。
参照图3，执行组件22包括限位装置、棘轮棘爪机构、螺杆与螺纹套，如图3所示，所述外壳内还设有限位装置，棘轮棘爪机构上的棘爪221与限位装置配合安装，通过限位装置控制棘爪的位移量，同时限位装置限定了棘爪221只能够沿着棘轮222的切线方向往复平移，所述外壳内安装有螺纹套，螺纹套内配合连接螺杆，螺杆与所述储液筒21内的活塞通过药液推杆相连，药液推杆一侧可设置有位移传感器用于监测推杆的的位移量，从而监测药液的输出量，保证整套系统的高可靠性，所述螺杆在转动时能够带动活塞在盛药筒内移动从而将药液注射进患者体内，所述滚轴转动设置于外壳内，螺杆的一端与滚轴相连，螺杆的另一端与活塞相连，通过滚轴的转动可以带动螺杆旋转给活塞提供推动力，棘轮棘爪机构包括棘爪221、棘轮222、棘轮套223、滚轴，滚轴的外侧套装棘轮套223，优选地，滚轴的两端部分别套装有棘轮套223；滚轴的外侧也可以套装一个棘轮套223或者套装更多个棘轮套223，例如三个、四个等等；棘轮套外侧安装棘轮222，棘轮222的外侧设有棘爪221，所述棘爪221的第一端与卡扣33相连，使得电磁驱动组件20在运行时能够通过支架与卡扣33带动棘爪221沿着棘轮的切线方向往返运动，棘爪221的另一端对应数个棘轮222设置为双爪或多爪形状从而与各个棘轮222分别啮合，通过棘爪221与对应的棘轮222分别啮合，从而使得棘爪棘轮啮合 时传动过程更加平稳、传动量更加准确，以便于棘轮通过滚轴带动螺杆定量转动从而精确的控制对患者的药液注射量，同时由于棘轮棘爪的单向传动机制，使得螺杆只能够单向传动从而能够通过控制活塞将药液推出。
参照图3、图4，所述针管组件包括针管41、胶管42、用于驱动针管组件中针头植入与拔出的针管控制装置40，针管41的针头优选为不锈钢针头，减少可能导致的细菌感染，针管41通过软管连接储液组件20，由储液组件20为针管供液；所述胶管42套设于针管41的外侧，针管41能够与胶管42之间发生相对运动，在需要对患者进行注射时，针管控制装置40控制针管41的针头伸出胶管42之外，完成注射后，针管控制装置40控制针管41上的针头重新收入胶管42之内，减少患者因针头长期存于体内产生的痛苦；后盖12即贴向患者身体的外壳一侧设有贴敷片13，贴敷片13上开设有针孔可供针管41上的针头穿过对患者实施药物注射，通过该种贴敷的方式取代了长导管的使用，避免了使用长导管时导管与用户身体摩擦、长导管可能挂在其他物体上等导致用户发生不适的现象发生。
参照图4，针管控制装置40包括安装架43、滑块组件45、斜面挡块组件46，弹性组件44，安装架43设于外壳之内，弹性组件44包括螺钉441，安装架43的一端安装有螺钉441，螺钉441外侧套装扭簧443，螺钉441的外侧转动连接有人字臂442，人字臂442的两臂之间转动连接，扭簧的转动可驱动人字臂442伸展或收缩，人字臂442包括转动连接在螺钉441外侧的第一连杆4421、与第一连杆4421转动连接的第二连杆4422，第二连杆4422的外端与滑块组件45上的滑动部转动连接，所述滑动组件45包括第一滑块451、第二滑块452与滑轨，所述第二连杆4422的外端与第一滑块451转动相连，第二连杆4422可驱动第一滑块451在滑块组件的滑轨上进行滑动，外壳中穿过有斜面挡块组件46，斜面挡块组件46位于外壳内部的一端连有挡块461，挡块461位于第一滑块与第二滑块之间，挡块分为两种使用状态，一种是当斜面挡块组件46向外拉动时，挡块461从第一滑块451与第二滑块452之间抽离，此时扭簧转动复位且其复位的过程中驱动人字臂伸展从而推动第一滑块451、第二滑块452在滑轨上进行移动；另一种是当斜面挡块组件46按下时，挡块461推动第一滑块451复位，可使得挡块461与第一滑块451接触的位置为斜面配合，便于第一滑块451的复位，当挡块推动第一滑块完全复位时，挡块461位于第一滑块451与第二滑块452之间将两者分隔开，此时扭簧被扭转，且扭簧有着复位推动第一滑块451运动的趋势，为下一次推动第一滑块451蓄力；第一滑块451上设有第一导通槽，第二滑块452上设有第二导通槽，第二导通槽用于容纳胶管42，第二滑块452上设有适配腔，胶管42上设有突出于胶管42的定位部421，定位部421适配于适配腔内，针管41通过该定位部421穿入胶管42内。
优选的，在注射完成后，胶管42留存于患者皮肤上的预留管内，而针管41收回到外壳内，以避免针头留在患者体内导致的并发症问题，具体的第二滑块452远离第一滑块451的一端开设有阻挡孔454，所述前盖11上对应设有一弹簧顶针453，所述第二滑块452滑动至一定位置后，所述弹簧顶针453弹出并插入所述阻挡孔454内，将所述第二滑块452固定住，从而使得胶管42不会被带动缩回，而第一滑块451在人字臂的收缩作用下复位缩回，针管41最终收回至胶管42内，在进行下次注射时，通过按钮件46的操作，再推动第一滑块451运动将针头管41推出即可。
参照图1、图2，控制主板组件50通过可拆卸连接的方式安装于外壳之内，可拆卸连接 的方式优选为螺钉连接，由于控制主板组件50为可拆卸式连接，使得本装置使用后，最为昂贵的控制主板组件50可拆卸下来进行再次利用，相对于现有技术来说，本装置的该种重复使用的方式极大减少了对该种设备的使用成本，降低了患者的医疗开支，提高了胰岛素泵的普适性，且控制主板组件50可通过蓝牙或无线网络与APP相连，通过APP的操作便于患者对本发明的操作控制，同时也可通过外壳上的控制面板对其进行控制；而外壳内可设有柔性线路板70这类能够连通控制主板组件50、能源组件60和泵液组件的元器件，保证本装置电路系统的正常运转；在检测到患者需要注入胰岛素时，控制斜面挡块组件解除对第一滑块的限制，针管组件插入患者皮下，然后启动电磁驱动组件20给执行组件22提供动力，使得储液组件20中的药液经过针管组件注入患者身体，注射完成后，斜面挡块组件推动第一滑块复位，第一滑块带动针管从患者体内拔出，便于下一次的植针使用。
本实施例中，贴敷式胰岛素泵还包括驱动复位机构，驱动复位机构包括用于与能源组件60可拆卸连接以向能源组件60补充能源的充电件以及用于与执行组件22可拆卸连接以使螺杆伸出抵推后收缩复位的复位件。具体地，通过能源组件60向控制主板组件50提供工作的电能，以使控制主板组件50控制执行组件22工作，进而使执行组件22的螺杆伸出抵推活塞以将药液注射进患者体内，在药液注射完成后，将螺杆与活塞分开，此时，活塞采用合适的方式处理方式弃置，将能源组件60与驱动复位机构中的充电件连接以储备足够的电能，同时将执行组件22与驱动复位机构中的复位件连接以使螺杆伸出抵推后收缩复位，以将能源组件60、控制主板组件50和执行组件22恢复至初始状态下可与新的活塞组装，进而可再次对患者注射使用，从而在满足医疗设备的相关规定的条件下，只弃置必须储液筒21和针管组件，即可实现对贴敷式胰岛素泵的反复使用，最大程度的降低了患者的使用成本。
所述能源组件60可以为纽扣电池等便于小型化的能源供给件，从而更加贴合本发明的设计要点，便于本发明的整体小型化设计，同时能源组件60也可以为外接电源，节省能源组件占用的空间。
值得一提的是，靠近胶管42端部的位置套设有密封胶体422，密封胶体422位于胶管42与贴敷片13的连接处，密封胶体的设置可防止液体流入壳体，起到良好的防水效果。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
