具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由下述所限定和覆盖的多种不同方式实施。
图1是本发明优选实施例的芯片级驱动胰岛素泵的结构示意图；图2是图1所示芯片级驱动胰岛素泵的分解示意图；图3是本发明优选实施例的芯片级驱动胰岛素泵中执行组件的立体示意图；图4是图3所示执行组件的分解示意图。
如图1和图2所示，本实施例的芯片级驱动胰岛素泵，包括用于向患者体内注射药液的注射组件1、与注射组件1连接的用于带动注射组件1工作的执行组件2、与执行组件2对应布设的用于通过电磁驱动的方式驱动执行组件2工作的芯片级电磁驱动组件3、与芯片级电磁驱动组件3连接的用于控制芯片级电磁驱动组件3工作的控制主板组件4以及与控制主板组件4电连接的用于提供能源的供能组件5；芯片级电磁驱动组件3包括基体组件31、布设于基体组件31内的U形铁芯以及后浇注形成并绕设于U形铁芯外的导电绕组，导电绕组与控制主板组件4电连接。具体地，本发明的芯片级驱动胰岛素泵，在需要向患者体内注射药液时，首先通过控制主板组件4控制芯片级电磁驱动组件3工作，以通过电磁驱动的方式驱动执行 组件2工作，进而带动注射组件1向患者体内注射药液，实现对患者的药液注射治疗，在注射过程中，供能组件5为控制主板组件4和芯片级电磁驱动组件3提供工作电能；通过在基体组件31内插入U形铁芯和浇注形成导电绕组，实现获得结构简单、体积小的芯片级电磁驱动组件3，胰岛素泵的小型化也易于实现，即可获得体积小的胰岛素泵，本方案通过基体组件31、U形铁芯和导电绕组提供电磁力的同时为芯片级电磁驱动组件3小型化提供结构基础，再通过供能组件5、控制主板组件4、芯片级电磁驱动组件3、执行组件2和执行组件2相互协同配合实现电磁驱动胰岛素泵工作，相对于现有技术中的电机驱动和记忆合金驱动，结构简单，体积小，隐蔽性好，携带方便，且电磁驱动使得动力输出更加稳定、直接、可靠，有利于精确控制对患者的胰岛素注入量，保证患者的身体健康，同时芯片级电磁驱动组件3和供能组件5可以集成在主板上，占用空间更小，实现小型化、微型化设计，便于穿戴及便携，对于患者的负担更小，也有利于节约成本。
本实施例中，基体组件31包括第一基体和第二基体，第一基体包括刻蚀形成的第一半边U形槽以及刻蚀形成并绕设于半U形槽外的第一半螺旋孔槽，第二基体包括刻蚀形成的第二半边U形槽以及刻蚀形成并绕设于半U形槽外的第二半螺旋孔槽，第一基体和第二基体相对扣合，以使第一半边U形槽和第二半边U形槽相对扣合并围合形成容纳U形铁芯的U形槽，并使第一半螺旋孔槽和第二半螺旋孔槽相互连通并围合形成用于后浇注形成导电绕组的螺旋孔槽。具体地，首先在第一基体和第二基体上分别刻蚀出第一半边U形槽、第一半螺旋孔槽、第二半边U形槽和第二半螺旋孔槽，然后第一基体和第二基体相对扣合形成基体组件，同时围合形成U形槽和螺旋孔槽，再向U形槽内插入U性铁芯，最后向螺旋孔槽内通入液态合金，固化后获得导电绕组。应当理解的是，浇注工艺、刻蚀工艺属于本领域技术人员的公知技术，具体步骤不过多赘述。
如图3和图4所示，本实施例中，执行组件2包括第一轴承座21、第二轴承座22、可转动地布设于第一轴承座21和第二轴承座22内的棘轮机构23、沿轴向可移动地布设于棘轮机构23内并与注射组件1连接的执行丝杆24以及可转动地布设并分别与棘轮机构23和U形铁芯对应布设的用于在U形铁芯的磁力作用下往复摆动以带动棘轮机构23步进式转动的摆动件25，U形铁芯包括指向相反的两磁极，控制主板组件4用于按预设频率改变导电绕组中的电流流向以改变两磁极的指向和磁性进而带动摆动件25往复摆动。具体地，通过向导电绕组传输电流，以使U形铁芯产生具体磁吸且指向相反的两磁极，进而一吸引一排斥摆动件25，以使摆动件25在磁力的作用下朝靠近其中一磁极的方向摆动，此时，通过控制主板组件4改变电流输出的正负极，进而改变两磁极的指向，从而使摆动件25在磁力的作用下朝靠近另一磁极的方向摆动，基于上述工作原理，控制主板组件4按预设频率改变两磁极的指向，以使摆动件25随两磁极指向的改变而往复摆动，进而带动棘轮机构23步进式转动，从动带动执行丝杆24沿轴向伸出抵推件工作，实现带动注射组件1向患者体内注射药液。应当理解的是，预设频率决定了摆动件25往复摆动的频率，进而决定了药液的注射速度，即可根据患者的使用需求自适应调节。可选地，预设频率为5毫秒/次，即每经过5毫秒改变一次导电绕组的电流流向，以改变U形铁芯上两磁极的指向，进而实现快速注射药液。应当理解的是，当U形铁芯处于静止状态时，指向北方的磁极叫做北极，指向南方的磁极叫做南极，而磁极指向的改变，即指的是将北极变为南极，将南极变为北极。
本实施例中，第一基体31设有朝执行组件2延伸形成的安装部，第二基体32设有朝执行组件2延伸形成的多个限位凸起，多个限位凸起间隔排布并与安装部围合形成限位腔，摆动件25可转动地布设于安装部上并位于限位腔内。具体地，通过U形铁芯上两磁极的指向变化而带动摆动件25于安装部上往复摆动，以带动棘轮机构23步进式转动，再通过限位凸起将摆动件25限制于限位腔内，以限制摆动件25的摆动范围，避免摆动件25的摆动范围过大而脱离棘轮机构23的对应区域，进而可能受到其他部件的干涉而卡死，从而保证摆动件25往复摆动的稳定性。
本实施例中，执行组件2还包括布设于第一轴承座21和第二轴承座22之间的安装壳体，安装壳体上包括沿高度方向布设的连接柱，摆动件25可转动地套设于连接柱上。具体地，通过U形铁芯上两磁极的指向变化而带动摆动件25于安装壳体上往复摆动，以带动棘轮机构23步进式转动。
如图4所示，本实施例中，摆动件25包括布设于两磁极之间的延伸区域的用于随两磁极的指向变化而往复摆动的磁吸部251以及与棘轮机构23对应布设的用于随磁吸部251的往复摆动而推动棘轮机构23步进式转动的抵推部252。具体地，磁吸部251随U形铁芯两磁极指向的改变而往复摆动，以带动磁吸件往复摆动，进而使抵推部252抵推棘齿沿棘轮机构23的切线方向步进式平移，从而带动棘轮机构23步进式正向转动，同时抵推部252抵推棘轮机构23，防止棘轮机构23反向转动；同时由于磁吸部251布设于两磁极之间的延伸区域，摆动件25的磁吸部251摆动过程中不会受到磁极的阻碍和干涉，摆动范围大，以使摆动部分涵盖的结构少，便于进行精简以及轻量化设计，其摆动部分的自身重力对于芯片级电磁驱动组件3的驱动动力可以忽略不记，使得随着胰岛素泵使用时的姿态的不同、或者姿态改变，对于芯片级电磁驱动组件3的影响小。应当理解的是，两磁极之间的延伸区域指的是，两磁极的中间区域朝执行组件2延伸的区域。可选地，安装壳体远离磁吸部251的端部设有沿安装壳体的高度方向布设的限位柱，多个限位柱沿安装壳体的长度方向间隔布设围合形成限位间隙，摆动件25上远离磁吸部251的端部设有沿摆动件25的长度方向延伸形成并伸入限位间隙内的用于在摆动件25摆动过程中与限位柱抵接以限制摆动件25的摆动范围的限位部；摆动件25摆动过程中，限位部同步摆动，由于限位部伸入限位间隙内而受到限位柱的抵接限位，而只能在限位间隙内摆动，使得摆动件25的摆动范围相应受到限制，避免摆动件25的摆动范围过大而使得抵推部252脱离棘爪机构的抵推区域，进而可能受到棘爪机构的阻碍干涉而卡死，保证摆动件25运动的稳定可靠。
如图3和图4所示，本实施例中，执行组件2还包括与第一轴承座21连接并靠近基体组件31布设的第一支撑座26以及与第二轴承座22连接并远离基体组件31布设的第二支撑座27，磁吸部251可摆动地布设于第一支撑座26上，摆动件25上远离磁吸部251的端部可转动地布设于第二支撑座27上。具体地，通过U形铁芯带动摆动件25于第一支撑座26上摆动，并相对于第二支撑座27转动，以推动棘轮机构23步进式转动。可选地，磁吸部251上开设有弧形槽，第一支撑座26上开设有与弧形槽对应布设的第一连接孔，执行组件2包括穿设于弧形槽以伸入第一连接孔内的第一连接销。
如图1所示，本实施例中，芯片级驱动胰岛素泵还包括第一壳体6以及插接于第一壳体6内的第二壳体7，供能组件5、控制主板组件4、芯片级电磁驱动组件3和执行组件2布设于 第一壳体6内，注射组件1布设于第二壳体7内，执行丝杆24与注射组件1可拆卸连接并用于伸出抵推注射组件1以向患者体内注射药液。具体地，在药液输注完成后，拆开第一壳体6和第二壳体7，第二壳体7采用合适的处理方式弃置，第一壳体6回收利用，患者仅需要花费相对较少的成本购置新的第二壳体7以与回收的第一壳体6进行拼装即可正常使用，经济环保，有利于资源的回收利用，使用过后的第二壳体7采用合适的处理方式抛弃；通过插接的第一壳体6和第二壳体7以及可拆卸连接的执行丝杆24和注射组件1，实现对第一壳体6以及第一壳体6内较为昂贵的供能组件5、控制主板组件4和芯片级电磁驱动组件3的回收利用，大大降低了患者的多次使用的成本。可选地，另一实施例中，供能组件5、控制主板组件4和芯片级电磁驱动组件3布设于第一壳体6内，注射组件1和执行组件2布设于第二壳体7内，可实现对第一壳体6内供能组件5、控制主板组件4和芯片级电磁驱动组件3的回收利用。可选地，另一实施例中，执行丝杆24与注射组件1固定连接，执行丝杆24与执行组件2可拆卸连接，可实现对第一壳体6内供能组件5、控制主板组件4、芯片级电磁驱动组件3以及不包括执行丝杆24的执行组件2的回收利用。
本实施例中，芯片级驱动胰岛素泵还包括用于分别与棘轮机构23和执行丝杆24可拆卸连接的以使伸出抵推后的执行丝杆24收缩复位的复位机构。具体地，通过复位机构使执行丝杆24伸出抵推后收缩复位，实现对执行丝杆24的回收利用。
本实施例中，芯片级驱动胰岛素泵还包括用于贴敷于患者体表的底板以及布设于底板上的用于插入患者体内的留置针，第一壳体6布设于底板上并开设有与留置针连通的第一注射孔，第二壳体7开设有与第一注射孔连通的第二注射孔，注射组件1的注射端穿设于第一注射孔和第二注射孔以与留置针连通。具体地，首先将底板贴敷于患者体表，并将留置针插入患者体内，再将插接的第一壳体6和第二壳体7布设于底板上，并使注射组件1的注射端穿设于第一注射孔和第二注射孔以与留置针连通，以向患者体内输注药液。可选地，注射组件1包括储液组件与针管组件，储液组件用于为患者的注射储存并提供药液，储液组件的一端连接执行组件2，储液组件的另一端连接针管组件，执行组件2能够将储液组件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，控制主板组件4用于控制执行组件2的关闭与具体运行过程。可选地，针管组件包括针管、胶管、用于驱动针管中的针头植入与拔出的针管控制装置，针管的针头优选为不锈钢针头，减少可能导致的细菌感染，针管通过软管连接储液组件，由储液组件为针管供液；胶管套设于针管的外侧，针管能够与胶管之间发生相对运动，在需要对患者进行注射时，针管控制装置控制针管的针头伸出胶管之外，完成注射后，针管控制装置控制针管上的针头重新收入胶管之内，减少患者因针头长期存于体内产生的痛苦。可选地，底板贴向患者身体一侧设有贴敷片，贴敷片上开设有针孔可供针管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患者发生不适的现象发生。可选地，针管控制装置包括安装架、滑块组件、斜面挡块组件和弹性组件，安装架设于外壳之内，弹性组件包括螺钉，安装架的一端安装有螺钉，螺钉外侧套装扭簧，螺钉的外侧转动连接有人字臂，人字臂的两臂之间转动连接，扭簧的转动可驱动人字臂伸展或收缩，人字臂包括转动连接在螺钉外侧的第一连杆、与第一连杆转动连接的第二连杆，第二连杆的外端与滑块组件上的滑动部转动连接，滑动组件包括第一滑块、第二滑块以及滑轨，第二连杆的外端与第一滑块转动相连，第二连杆可驱动第一滑块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，斜面挡块组件位于外壳内部的一端连有挡块，挡块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向外拉动时，挡块从第一滑块与第二滑块之间抽离，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、第二滑块在滑轨上进行移动；另一种是当斜面挡块组件按下时，挡块推动第一滑块复位，可使得挡块与第一滑块接触的位置为斜面配合，便于第一滑块的复位，当挡块推动第一滑块完全复位时，挡块位于第一滑块与第二滑块之间将两者分隔开，此时扭簧被扭转，且扭簧有着复位推动第一滑块运动的趋势，为下一次推动第一滑块蓄力；第一滑块上设有第一导通槽，第二滑块上设有第二导通槽，第二导通槽用于容纳胶管，第二滑块上设有适配腔，胶管上设有突出于胶管的定位部，定位部适配于适配腔内，针管通过该定位部穿入胶管内。优选地，在注射完成后，胶管留存于患者皮肤上的预留管内，而针管收回到外壳内，以避免针头留在患者体内导致的并发症问题，具体地，第二滑块远离第一滑块的一端开设有阻挡孔，前盖上对应设有一弹簧顶针，第二滑块滑动至一定位置后，弹簧顶针弹出并插入阻挡孔内，将第二滑块固定住，从而使得胶管不会被带动缩回，而第一滑块在人字臂的收缩作用下复位缩回，针管最终收回至胶管内，在进行下次注射时，通过按钮件的操作，再推动第一滑块运动将针头管推出即可。
如图4所示，本实施例中，棘轮机构23包括可转动地布设于第一轴承座21和第二轴承座22内的转动轴231以及固定套设于转动轴231外并与摆动件25对应布设的棘轮232，转动轴231沿轴向开设有与执行丝杆24螺纹连接的连接腔。具体地，摆动件25带动棘轮232步进式转动，进而带动转动步进式转动，从而带动执行丝杆24步进式轴向移动。
