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驱动复位胰岛素泵的结构示意图；图2是本发明优选实施例的驱动复位胰岛素泵的部分结构示意图；图3是图2所示驱动复位胰岛素泵的分解示意图；图4是图2所示驱动复位胰岛素泵中部分结构的分解示意图；图5是本发明优选实施例的驱动复位胰岛素泵的部分结构示意图。
如图1所示，本实施例的驱动复位胰岛素泵，包括用于对患者进行注射操作的注射组件1、用于控制注射组件1对患者进行注射的执行组件2、用于控制执行组件2工作的控制组件3、用于向控制组件3提供电能的能源组件4以及分别与能源组件4和执行组件2可拆卸连接的驱动复位机构5，能源组件4、控制组件3和执行组件2为整体式结构，执行组件2包括与注射组件1可拆卸连接的用于抵推注射组件1以对患者进行注射操作的抵推丝杆21，驱动复位 机构5包括用于与能源组件4可拆卸连接以向能源组件4补充能源的充电件51以及用于与执行组件2可拆卸连接以使抵推丝杆21伸出抵推后收缩复位的复位件52。具体地，本发明的驱动复位胰岛素泵，通过能源组件4向控制组件3提供工作的电能，以使控制组件3控制执行组件2工作，进而使执行组件2的抵推丝杆21伸出抵推注射组件1以将药液注射进患者体内，在药液注射完成后，将抵推丝杆21与注射组件1分开，此时，注射组件1采用合适的处理方式弃置，将能源组件4与驱动复位机构5中的充电件51连接以储备足够的电能，同时将执行组件2与驱动复位机构5中的复位件52连接以使抵推丝杆21伸出抵推后收缩复位，以将能源组件4、控制组件3和执行组件2恢复至初始状态下可与新的注射组件1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，只弃置必须弃置的注射组件1，即可实现对驱动复位胰岛素泵的反复使用，最大程度的降低了患者的使用成本；本方案通过驱动复位机构5实现对能源组件4、控制组件3和执行组件2的回收利用，以使患者在使用过程中只需要更换注射组件1，即可反复使用驱动复位胰岛素泵，大大降低了患者长时间使用的使用成本，在满足1型糖尿病患者需求的同时，便于向2型糖尿病患者与妊娠糖尿病患者普及，实用性强，适于广泛推广和应用。应当理解的是，1型糖尿病患者病情严重，因此，需要使用疗效好的胰岛素泵进行治疗，2型糖尿病患者与妊娠糖尿病患者病情相对较轻，有多种治疗方案，而一般的胰岛素泵价格昂贵且使用麻烦，不被2型糖尿病患者与妊娠糖尿病患者所接受，而本申请中驱动复位胰岛素泵能大大降低长时间使用的使用成本，价格相对较低，且便于携带和使用，即便于向2型糖尿病患者与妊娠糖尿病患者推广普及。
如图2和图5所示，本实施例中，执行组件2包括驱动件22、支撑壳体23、可活动地布设于支撑壳体23上并与驱动件22对应布设的摆动件24、可转动地布设于支撑壳体23上并与摆动件24对应布设的棘轮机构25以及固定布设于棘轮机构25内并套设于抵推丝杆21外的丝杆套26，丝杆套26与抵推丝杆21螺纹连接，驱动件22用于驱动摆动件24摆动，棘轮机构25用于带动丝杆套26转动，丝杆套26用于带动抵推丝杆21伸出抵推或者收缩复位，摆动件24用于推动棘轮机构25正向转动以带动丝杆套26正向转动进而带动抵推丝杆21伸出抵推于丝杆套26外，复位件52用于分别与抵推丝杆21和棘轮机构25可拆卸连接以带动棘轮机构25反向转动进而带动丝杆套26反向转动从而带动抵推丝杆21收缩复位于丝杆套26内。具体地，通过支撑壳体23对摆动件24、棘轮机构25、丝杆套26和抵推丝杆21进行稳定支撑，以保证摆动件24、棘轮机构25、丝杆套26和抵推丝杆21之间相互运动的可靠性，在进行药液注射时，驱动件22驱动摆动件24往复摆动，以带动棘轮机构25步进式正向转动，进而带动丝杆套26步进式正向转动，从而带动抵推丝杆21步进式伸出抵推，实现将药液注射至患者体内，在药液注射完成后，再将棘轮机构25和抵推丝杆21连接复位件52，以使复位件52带动棘轮机构25反向转动，进而带动丝杆套26反向转动，从而带动抵推丝杆21收缩复位于丝杆套26内，以使执行组件2可抵推下一个注射组件1，完成下一个注射组件1的药液注射。应当理解的是，抵推丝杆21和注射组件1或者复位件52可拆卸连接，当棘轮机构25带动丝杆套26转动时，抵推丝杆21只能沿轴向移动以完成注射组件1的注射作业或者沿轴向移动实现收缩复位，而不能随着丝杆套26的转动而同步转动，即抵推丝杆21是周向固定的。
如图3所示，本实施例中，棘轮机构25包括可转动地布设于支撑壳体23上并固定套设于丝杆套26外的转动轴251、可单向转动地套设于转动轴251外的棘轮252以及沿棘轮252 的周向依次排布的多个棘齿，转动轴251与复位件52可拆卸连接。具体地，当需要注射药液时，通过摆动件24抵推棘齿以带动棘轮252正向转动，此时，棘轮252带动转动轴251正向转动，进而带动丝杆套26正向转动，从而实现连抵推丝杆21的伸出抵推；当复位件52带动转动轴251反向转动时，转动轴251相对于棘轮252反向转动，即棘轮252固定不同，而不会与摆动件24发生抵接干涉，转动轴251带动丝杆套26反向转动，进而带动抵推丝杆21轴向移动收缩复位于丝杆套内26。可选地，转动轴251采用内部中空的套筒结构。
如图1所示，本实施例中，复位件52包括复位电机521、布设于复位电机521的输出轴上并与转动轴251可拆卸连接的连接套522以及与抵推丝杆21可拆卸连接的用于防止抵推丝杆21周向转动的活动套筒。具体地，复位电机521工作，以带动输出轴转动，进而带动连接套522转动，从而带动转动轴251转动，最后带动丝杆套26转动，且由于活动套筒防止抵推丝杆21周向转动，以使抵推丝杆21相对于丝杆套26轴向移动，实现抵推丝杆21的收缩复位。可选地，活动套筒包括与抵推丝杆21同轴布设的活动套筒、沿轴向可活动地布设于活动套筒内并与抵推丝杆21的伸出端可拆卸连接的活动限位块以及从底部支撑活动套筒的支撑座，通过活动限位块与抵推丝杆21连接，以防止抵推丝杆21和丝杆套26同步周向转动。
如图5所示，本实施例中，驱动件22包括电磁体221以及与电磁体221电连接的供电件222，电磁体221包括间隔布设且指向相反的两磁极，供电件222用于按预设频率改变两磁极的磁性和指向以带动摆动件24往复摆动。具体地，通过供电件222向电磁体221传输电流，以使电磁体221产生具备磁性且指向相反的两磁极，进而一吸引一排斥摆动件24，以使摆动件24在磁力的作用下朝靠近其中一磁极的方向摆动，此时，供电件222通过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24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，供电件222按预设频率改变两磁极的指向，以使摆动件24随两磁极指向的改变而在两磁极之间的延伸区域往复摆动，进而带动抵推丝杆21伸出抵推，从而驱动注射组件1注射药液，通过采用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，同时电生磁的能量转化效率相对于电生热的能量转换效率高，功耗低，在同样电力的情况下使用时间长，便于患者长时间使用。应当理解的是，预设频率决定了摆动件24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毫秒改变一次供电件222的电流流向，以改变电磁体221两磁极的指向，进而实现快速注射药液。可选地，电磁体221的形状呈“U”形布设，两磁极分别布设于电磁体221开口端的两端部。应当理解的是，当电磁体221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，而供电件222改变磁极的指向，指的是将北极变为南极，将南极变为北极。应当理解的是，当供电件222向电磁体221提供电流时，电磁体221具备磁性并产生吸引和排斥摆动件24的磁力，进而驱使抵推丝杆21伸出抵推；当供电件222不向电磁体221提供电流时，电磁体221停止工作，相应地，抵推丝杆21也无法工作。应当理解的是，另一实施例中，驱动件22采用记忆合金驱动摆动件24摆动。
如图3所示，本实施例中，支撑壳体23包括沿支撑壳体23的高度方向布设的连接柱231，摆动件24可转动地套设于连接柱231上，摆动件24包括布设于两磁极之间的延伸区域且与电磁体221保持预设间距的用于随两磁极磁性的改变而往复摆动的磁吸部241以及用于随磁 吸部241的往复摆动而抵推棘轮机构25转动的抵推部242。具体地，通过电磁体221带动磁吸部241反复摆动，以带动抵推部242反复摆动，进而抵推棘轮机构25，实现棘轮机构25的步进式转动，从而带动抵推丝杆21伸出抵推注射组件1，完成注射作业。可选地，磁吸部241采用铁磁性材料制成。可选地，磁吸部241为电磁铁。应当理解的是，由于磁吸部241与电磁体221保持预设间距，摆动件24的磁吸部241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，以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驱动件22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，对于驱动件22的影响小。应当理解的是，供电件222提供的电流越大，电磁体221上两磁极的磁力越大，磁吸部241的摆动速度越快。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。
如图3所示，本实施例中，支撑壳体23的侧壁上设有沿支撑壳体23的宽度方向延伸形成的多个限位凸起232，多个限位凸起232沿支撑壳体23的长度方向间隔布设围合形成限位槽，摆动件24还包括沿摆动件24的厚度方向开设并与限位槽对应布设的限位孔243以及布设于限位孔243内的限位块244，限位块244的限位端伸入限位槽内用于在摆动件24摆动过程中与限位凸起232抵接以限制摆动件24的摆动范围。具体地，摆动件24摆动过程中，限位块244同步摆动，由于限位块244的限位端伸入限位槽内而受到限位凸起232的抵接限位，而只能在限位槽内摆动，使得摆动件24的摆动范围相应受到限制，避免摆动件24的摆动范围过大而使得抵推部242脱离棘齿的抵推区域，进而可能受到棘齿的阻碍干涉而卡死，保证磁吸件运动的稳定可靠。可选地，限位槽沿支撑壳体23的长度方向布设，支撑壳体23的长度方向与磁吸部241的摆动方向相同，以使限位块244沿摆动方向可滑动地布设于限位槽内，通过限位块244在限位槽内滑动，以适当的增加摆动件24的摆动范围，避免摆动件24的摆动范围过小而使得抵推部242的抵推行程过小，以使棘轮252的转动速度过慢，进而影响注射组件1的注射速度。应当理解的是，预设间距可根据产品的生产需求自适应调节，能实现磁吸部241的摆动即可。
如图3所示，本实施例中，支撑壳体23远离磁吸部241的端部设有沿支撑壳体23的高度方向布设的多个限位柱233，多个限位柱233沿支撑壳体23的长度方向间隔布设围合形成限位间隙，摆动件24上远离磁吸部241的端部设有沿摆动件24的长度方向延伸形成并伸入限位间隙内的用于在摆动件24摆动过程中与限位柱233抵接以限制摆动件24的摆动范围的限位部245。具体地，摆动件24摆动过程中，限位部245同步摆动，由于限位部245伸入限位间隙内而受到限位柱233的抵接限位，而只能在限位间隙内摆动，使得摆动件24的摆动范围相应受到限制，避免摆动件24的摆动范围过大而使得抵推部242脱离棘齿的抵推区域，进而可能受到棘齿的阻碍干涉而卡死，保证摆动件24运动的稳定可靠。
如图3所示，本实施例中，摆动件24还包括套设于连接柱231上的用于抵压摆动件24的弹性件246。具体地，通过弹性件246抵压摆动件24，以使摆动件24上的抵推部242可始终与棘轮252上的一棘齿处于同一水平面，进而可始终抵推一棘齿沿棘轮252的切线方向步进式移动，实现棘轮252的步进式转动。可选地，弹性件246为压缩弹簧。
如图4所示，本实施例中，棘轮252沿转动轴251的轴向布设有多个，抵推部242与棘轮252一一对应布设。具体地，两个抵推部242分别布设于磁吸件上磁吸部241的相对两侧， 磁吸部241往复摆动的过程中，两个抵推部242依次往复抵推两个棘轮252上的棘齿，大大提高了棘轮252的转动速度。应当理解的是，当磁吸部241朝靠近其中一磁极的方向运动时，靠近该磁极的抵推部242抵推对应的棘轮252上的棘齿，进而使该棘轮252转动；当磁吸部241朝靠近另一磁极的方向运动时，靠近另一磁极的抵推部242抵推对应的棘轮252上的棘齿，进而使该棘轮252转动，由于两棘轮252通过转动轴251实现同步转动，即其中一棘轮252转动，另一棘轮252也相应同步转动，磁吸部241往复摆动一次，即可使棘轮252转动两次，棘轮252的转动速度大大提高。
如图1所示，本实施例中，能源组件4包括充电插口，充电件51包括充电座511以及布设于充电座511上的用于插入充电插口的充电插头512。具体地，在注射组件1注射完成后，将执行组件2与注射组件1拆分，然后将充电插口与充电插头512插接配合，以对能源组件4进行充电。可选地，充电件51包括充电线，充电插头512布设于充电线的活动端上。
本实施例中，驱动复位胰岛素泵还包括外壳以及与外壳可拆卸连接的底板，能源组件4、控制组件3和执行组件2固定布设于外壳上，注射组件1固定布设于底板上。具体地，在注射组件1注射药液后，将外壳与底板拆分，然后将底板以及固定布设于底板上的注射组件1采用合理的方式弃置，将外壳以及固定布设于外壳上的能源组件4、控制组件3和执行组件2回收反复利用。
本实施例中，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，控制组件3用于控制执行组件2的关闭与具体运行过程。
本实施例中，外壳和底板之间的连接处设有用于防水的防水胶圈，以起到良好的防水效果。可选地，所述储液组件包括用于盛装药液的储液筒与配合安装在储液筒内的活塞，活塞在储液筒内移动时能够将其内的药液向针管组件内推出。
本实施例中，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。
本实施例中，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。可选地，能源组件4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4也可以为外接电源，节省能源组件4占用的空间。
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。
