Description

磁力驱动注射装置 【技术领域】
本发明是关于一种注射装置的技术领域，特别是一种通过磁力驱动且可重复使用的磁力驱动注射装置。
【背景技术】
现有技术的注射装置在执行药剂注射程序时，需要通过用户持续施加外力至推杆，以推动药剂注入人体中。随着医疗技术的进步，具有辅助驱动力的自动注射装置已经广泛的被应用。用户只要通过单手操作自动注射装置，即可驱动内部推杆移动以完成药剂的注射，甚至是将推杆退回注射前的位置以便重复使用自动注射装置，如此可提高注射的便利性及灵活度。
目前常见的自动注射装置大多采用弹簧或马达作为移动推杆的驱动力来源。然而，当自动注射装置采用弹簧驱动时，需要搭配装置内部的多个组件彼此间的结构配置及卡合设计，才能完成推杆移动后固定及退回等操作，在结构组装上往往过于复杂；再者，采用马达驱动时需要搭配螺杆来带动推杆移动，一方面需要提供额外电力供马达运作，另一方面因为马达的设置导致自动注射装置在设计上难以缩减其体积及重量，造成制造成本的增加。
因此，如何能简化组装零件的结构，且更能有效驱动推杆来回移动，以利于使用者操作，实为一个值得研究的课题。
【发明内容】
本发明是鉴于上述的技术问题而做出的，其目的在于，提供一种磁力驱动注射装置，其能藉由磁力的变化作为驱动力以对药剂执行注射操作或远离药剂，简化结构设计，并能达到重复使用的效果。
本发明的磁力驱动注射装置，包括套筒、供电单元、第一作动件、第二作 动件以及磁力产生单元。套筒包括通道；供电单元结合在套筒；第一作动件设置在通道内；第二作动件可移动的设置在通道内，且第二作动件可相对于第一作动件沿着轴线移动；以及磁力产生单元电性连接供电单元，且磁力产生单元选择性的结合第一作动件或第二作动件。其中通过供电单元对磁力产生单元供应电流，使得第一作动件及第二作动件之间形成磁性相吸力或磁性相斥力，进而驱动第二作动件接近药瓶以执行注射操作或在注射操作完成后远离药瓶。
在本发明的一个实施例中，磁力产生单元包括线圈部及驱动控制部，线圈部环绕第一作动件或第二作动件，且线圈部的两端分别电性连接驱动控制部。
在本发明的一个实施例中，当线圈部环绕第一作动件时，第一作动件为金属杆，而第二作动件为永久磁铁。
在本发明的一个实施例中，当线圈部环绕第二作动件时，第一作动件为永久磁铁，而第二作动件为金属杆。
在本发明的一个实施例中，套筒还包括至少一操作件，且至少一操作件电性连接供电单元及驱动控制部。
在本发明的一个实施例中，驱动控制部为驱动电路板。
在本发明的一个实施例中，供电单元包括充电埠，且充电埠外露于套筒。
在本发明的一个实施例中，套筒还包括观测窗，且观测窗的设置位置对应药瓶在套筒的通道内的装设位置。观测窗对应药瓶的装设位置而设置。
在本发明的一个实施例中，磁力驱动注射装置还包括胶塞，胶塞设置在药瓶及第二作动件之间。
在本发明的一个实施例中，套筒还包括至少一导引件，且第二作动件还包括至少一对应导引件；当第二作动件相对于套筒移动时，藉由至少一对应导引件配合至少一导引件使得第二作动件沿着轴线移动。
本发明的磁力驱动注射装置通过供应电流至磁力产生单元以产生磁力，使得第一作动件及第二作动件之间形成磁性相吸力或磁性相斥力，进而驱动第二作动件推动药瓶以执行注射操作或远离药瓶。一旦供应至磁力产生单元的电流方向改变，第二作动件的移动方向也随之改变，即可轻易执行本发明的磁力驱动注射装置的药剂注射或更换，并且能够有效简化装置内各部件的结构设计，提高组装的便利性。
本发明所采用的具体技术，将通过以下的实施例及附呈图式作进一步的说明。

由于各种态样与实施例仅为例示性且非限制性，故在阅读本说明书后，具有通常知识者在不偏离本发明的范畴下，亦可能有其他态样与实施例。根据下述的详细说明与申请专利范围，将可使该等实施例的特征及优点更加彰显。
在本文中，是使用「一」或「一个」来描述本文所述的组件和组件。此举只是为了方便说明，并且对本发明的范畴提供一般性的意义。因此，除非很明显的另指他意，否则此种描述应理解为包括一个或至少一个，且单数也同时包括多个。
在本文中，用语「第一」或「第二」等类似序数词主要是用以区分或指涉相同或类似的组件或结构，且不必然隐含此等组件或结构在空间或时间上的顺序。应了解的是，在某些情形或组态下，序数词可以交换使用而不影响本发明的实施。
在本文中，用语「包括」、「具有」或其他任何类似用语意欲涵盖非排他性的包括物。举例而言，含有多个要件的组件或结构不仅限于本文所列出的此等要件而已，而是可以包括未明确列出但却是该组件或结构通常固有的其他要件。
在本文中，用语「药瓶」是指可容置药剂以供执行注射操作的部件。药瓶可以是单纯存储药剂的容器，或者是可结合注射针头或其他部件的容器。其中通过推杆或类似件推抵药瓶内的药剂，可将药剂经过注射针头注入人体内，以完成注射操作。
本发明的磁力驱动注射装置可供装设药瓶以执行注射操作。请先参考图1及图2，其中图1是本发明的磁力驱动注射装置的外观示意图，图2是本发明的磁力驱动注射装置第一实施例的剖视图。如图1及图2所示，本发明的磁力驱动注射装置1包括套筒10、供电单元20、第一作动件30、第二作动件40以及磁力产生单元50。套筒10包括通道11，且通道11对应一个轴线L。通道11可供设置装置的必要部件，且设置在通道11内的可移动部件可沿着轴线L的方向相对于套筒10移动；药瓶90可装设在套筒10内的通道11的一端。套筒10可采用较坚固的材质制成，例如塑性材料、金属或合金等，但本发明不以此为限。
在本发明的一个实施例中，套筒10还包括观测窗13。观测窗13设置在套筒10的外表面，且观测窗13的设置位置对应药瓶90在套筒10的通道11内的装设位置。因此，使用者可通过观测窗13检视目前药瓶90内的药剂的残量，以决定是否更换药瓶90或补充药剂。此外，在本发明的一个实施例中，套筒10还包括盖体15。盖体15的设置位置对应于药瓶90的注射针头的位置。因此，本发明的磁力驱动注射装置在未使用的状态下，可藉由盖体15遮蔽药瓶90的注射针头，以避免使用者误触。
供电单元20结合在套筒10，以供应本发明的磁力驱动注射装置1内各部件所需的电力。依据不同结构设计，供电单元20可直接设置在套筒10的通道11内，例如设置在通道11远离药瓶90的另一端，或者供电单元20也可以独立设置在通道11外。在本发明的一个实施例中，供电单元20可以是可充电的电池模块，且供电单元20可包括充电埠21。充电埠21外露于套筒10，使得充电埠21可通过传输线直接连接家用插座或行动电源，以便针对供电单元20执行充电操作。
此外，在本发明的一个实施例中，套筒10还包括操作件12，且操作件12电性连接供电单元20。使用者可以通过操作件12切换供电单元20的供电状态，以启动或关闭本发明的磁力驱动注射装置1，或者通过操作件12切换、执行或指示相应功能。操作件12可由单纯的按键组成，或者操作件12可采用触摸屏来供使用者操作，也可结合前述二者。
第一作动件30及第二作动件40均设置在套筒10的通道11内，且第二作动件40位在第一作动件30及药瓶90之间。第一作动件30及第二作动件40均可采用杆状件。在作动设计上，第二作动件40可相对于第一作动件30沿着轴线L在通道11内移动。第二作动件40可因应不同的移动方向以接近药瓶90或远离药瓶90。
磁力产生单元50电性连接供电单元20，且磁力产生单元50可选择性的结合第一作动件30或第二作动件40。在本发明的一个实施例中，磁力产生单元50包括线圈部51及驱动控制部52，且线圈部51的两端分别电性连接驱动控制部52。磁力产生单元50则通过驱动控制部52电性连接供电单元20。线圈部51可为螺线型线圈，使得线圈部51可依据不同设计选择性的环绕在第一作动件30或第二作动件40。驱动控制部52可为驱动电路板，用以控制供应至线圈部51的电流方向及电流大小。
在本发明的第一实施例中，线圈部51环绕第一作动件30，使得磁力产生单元50结合第一作动件30以形成一个电磁铁，而第二作动件40则作为推杆。其中 第一作动件30为金属杆(例如铁杆、镍杆等铁磁性部件)，而第二作动件40为永久磁铁。
在本发明的一个实施例中，前述操作件12还可以电性连接磁力产生单元50的驱动控制部52。使用者可以通过操作件12控制驱动控制部52，例如改变供应至线圈部51的电流方向及电流大小等。
此外，本发明的磁力驱动注射装置1还包括胶塞60。胶塞60设置在套筒10的通道11内，且胶塞60位在第二作动件40及药瓶90之间。当第二作动件40朝药瓶90移动时，第二作动件40可通过推抵胶塞60，以间接推动药瓶90内的药剂注入人体中以完成注射操作。在本发明的一个实施例中，胶塞60可固定在第二作动件40接近药瓶90的一端，但本发明不以此为限。
以下将针对本发明的磁力驱动注射装置1的第一实施例的作动原理作详细说明。请参考图3及图4，其中图3是使用本发明的磁力驱动注射装置第一实施例执行注射操作时的示意图，图4是使用本发明的磁力驱动注射装置第一实施例在完成注射操作后的示意图。
如图3及图4所示，当使用者想要使用本发明的磁力驱动注射装置1来执行注射操作时，首先可通过操作件12控制供电单元20开始供电。供电单元20会对磁力产生单元50供应电流，当电流经由驱动控制部52供应至线圈部51时，随着电流方向不同，可基于安培右手定则在第一作动件30的两端相应形成N极和S极。此时，配合第二作动件40为永久磁铁的设计，使得第一作动件30及第二作动件40之间形成磁性相吸力或磁性相斥力，进而驱动第二作动件40朝药瓶90移动或远离药瓶90。
举例来说，当流经线圈部51的电流方向如图3所示时，基于安培右手定则将在第一作动件30接近第二作动件40的一端形成N极，且在远离第二作动件40的一端形成S极。此时，配合第二作动件40在接近第一作动件30的一端为N极，且在 远离第一作动件30的一端为S极，即可使得第一作动件30及第二作动件40之间形成磁性相斥力，以驱动第二作动件40朝药瓶90移动，进而推动药瓶90内的药剂执行注射操作。
当使用者使用本发明的磁力驱动注射装置1完成注射操作后，可通过操作件12控制驱动控制部52改变电流方向。举例来说，当流经线圈部51的电流方向如图4所示时，同样基于安培右手定则将在第一作动件30接近第二作动件40的一端形成S极，且在远离第二作动件40的一端形成N极。此时，配合第二作动件40在接近第一作动件30的一端为N极，且在远离第一作动件30的一端为S极，即可使得第一作动件30及第二作动件40之间形成磁性相吸力，进而驱动第二作动件40朝第一作动件30移动以远离药瓶90。之后使用者即可取下使用过的药瓶90并更换新药瓶90，以利于重复使用本发明的磁力驱动注射装置1执行另一次注射操作。
据此，本发明的磁力驱动注射装置1可通过控制电流所产生的磁极变化，以磁力驱动轻易完成注射操作，并且可提供重复注射的效果。
此外，在本发明的第一实施例中，套筒10还包括至少一导引件14，且第二作动件40还包括至少一对应导引件41。当第二作动件40相对于套筒10移动时，通过至少一对应导引件41配合至少一导引件14使得第二作动件40能保持沿着轴线L移动。各导引件14为凸块，而各对应导引件41为供凸块插入及移动的直线状沟槽，且直线状沟槽是沿平行轴线L方向延伸。前述各导引件14及各对应导引件41的结构可互换。此处导引件14的设置数量及位置会对应各对应导引件41的设置数量及位置。
请一并参考图5至图7，其中图5是本发明的磁力驱动注射装置第二实施例的剖视图，图6是使用本发明的磁力驱动注射装置第二实施例执行注射操作时的示 意图，图7是使用本发明的磁力驱动注射装置第二实施例在完成注射操作后的示意图。本发明的磁力驱动注射装置第二实施例为前述第一实施例的变化型式。
如图5所示，在本发明的磁力驱动注射装置1a第二实施例中，线圈部51是环绕第二作动件40，使得磁力产生单元50结合第二作动件40以形成一个电磁铁并同时作为推杆。其中第一作动件30为永久磁铁，而第二作动件40为金属杆(例如铁杆、镍杆等铁磁性部件)。
由此可知，当供电单元20供应电流经由驱动控制部52供应至线圈部51时，随着电流方向不同，可基于安培右手定则在第二作动件40的两端相应形成N极和S极。此时，配合第一作动件30为永久磁铁的设计，使得第一作动件30及第二作动件40之间形成磁性相吸力或磁性相斥力，进而驱动第二作动件40及磁力产生单元50一併朝药瓶90移动或远离药瓶90。
举例来说，当流经线圈部51的电流方向如图6所示时，基于安培右手定则将在第二作动件40接近第一作动件30的一端形成N极，且在远离第一作动件30的一端形成S极。此时，配合第一作动件30在接近第二作动件40的一端为N极，且在远离第二作动件40的一端为S极，即可使得第一作动件30及第二作动件40之间形成磁性相斥力，以驱动第二作动件40及磁力产生单元50一併朝药瓶90移动，进而推动药瓶90内的药剂执行注射操作。
当使用者使用本发明的磁力驱动注射装置1a完成注射操作后，可通过操作件12控制驱动控制部52改变电流方向。举例来说，当流经线圈部51的电流方向如图7所示时，同样基于安培右手定则将在第二作动件40接近第一作动件30的一端形成S极，且在远离第一作动件30的一端形成N极。此时，配合第一作动件30在接近第二作动件40的一端为N极，且在远离第二作动件40的一端为S极，即可使得第一作动件30及第二作动件40之间形成磁性相吸力，进而驱动第二作动件40及磁力产生单元50一併朝第一作动件30移动以远离药瓶90。
以上实施方式本质上仅为辅助说明，且并不欲用以限制申请目标的实施例或多个实施例的应用或用途。此外，尽管已在前述实施方式中提出至少一例示性实施例，但应了解本发明仍可存在大量的变化。同样应了解的是，本文所述的实施例并不欲用以通过任何方式限制所请求的申请目标的范围、用途或组态。相反的，前述实施方式将可提供本领域具有通常知识者一种简便的指引以实施所述的一或多种实施例。再者，可对组件的功能与排列进行各种变化而不脱离权利要求所界定的范畴，且权利要求包括已知的均等物及在本专利申请案提出申请时的所有可预见均等物。
