进一步的，在本发明方案中，当驱动单元一侧的驱动臂推动轮齿时，该侧多个驱动臂在推动方向所在的直线相交。由于驱动轮圆周表面整体呈圆弧形，相邻轮齿的被推动的齿面之间并不是相互平行的，一侧多个驱动臂在推动方向所在的直线相交能够保证在推动时，驱动臂的推动方向与轮齿推动面相垂直，提高推动的效率。
进一步的，本发明的技术方案中，轮齿为棘轮齿。在和驱动臂相互配合的使用下，采用棘轮齿能够有效防止驱动轮反转。另外，驱动单元单次向一个方向转动的整个过程中，驱动单元通过转动和停止转动的交替动作，带动驱动臂交替地推动和停止推动棘轮齿，使驱动轮交替地转动和停止转动，以对驱动轮实施多档推动。在单次向一个方向转动的整个过程中，驱动单元通过转动-停止转动-转动-…相交替的方式，将输注的药物割裂为更小的输注量，进而实现精确输注。
进一步的，驱动单元的多个档位包括大档位和小档位。患者可以根据实际的输注量和输注速率的需求，自由选择和切换大档位或小档位进行输注，使得输注过程更加灵活可控，大大提高了输注效率。
进一步的，驱动单元的多个档位还包括一个或多个中间档位。设置的中间档位为患者提供更多的输注选择，患者对输注过程的控制更加灵活。

具体实施方式
如前所述，现有技术的输注器件只有一个档位的输注模式，不能灵活控制输注过程。
经研究发现，造成上述问题的原因为：现有技术的药物输注设备只能够一档推动驱动轮转动以进行输注，驱动单元通过一个档位转动不能够在中间经过多次旋-停而实施多档推动，导致现有技术对输注过程的控制比较单一。
为了解决该问题，本发明提供了一种药物输注装置，驱动单元通过多档位转动，进而对驱动轮实施多档推动。对多个档位的切换和选择，患者灵活控制了药物的输注过程。同时有效降低了该输注设备的最小药物输注量，减弱了患者体液状态的波动。
现在将参照附图来详细描述本发明的各种示例性实施例。应理解，除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不应被理解为对本发明范围的限制。
此外，应当理解，为了便于描述，附图中所示出的各个部件的尺寸并不必然按照实际的比例关系绘制，例如某些层的厚度或宽度可以相对于其他层有所放大。
以下对示例性实施例的描述仅仅是说明性的，在任何意义上都不作为对本发明及其应用或使用的任何限制。这里对于相关领域普通技术人员已知的技术、方法和装置可能不作详细讨论，但在适用这些技术、方法和装置情况下，这些技术、方法和装置应当被视为本说明书的一部分。
应注意，相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义或说明，则在随后的附图说明中将不需要对其进行进一步讨论。
图1为本发明实施例的药物输注装置结构的俯视示意图，药物输注装置包括了驱动单元100、驱动轮130、储药单元150、活塞160、螺杆170以及动力单元180。
螺杆170分别与活塞160和驱动轮130相连接。在本发明实施例中，驱动轮130活动设置于装置底座(未示出)上，驱动轮130通过转动推动螺杆170运动，进而推动设置于储药单元150中的活塞160向前运动，以达到注射药物的目的。
驱动单元100用于推动驱动轮130转动。驱动单元100通过转轴120活动连接于装置底座上。动力单元180用于对驱动单元100施加力的作用，使得驱动单元100转动。在本发明的实施例中，动力单元180固定连接在驱动单元100的顶部位置140处，进而将动力单元180分为左右两个部分，如图1中A’方向部分和B’方向部分，进而在A’方向或者B’方向上交替拉动驱动单元100绕着转轴120转动。具体的，在本发明实施例中，当动力单元180在A’方向拉动驱动单元100时，驱动单元100绕着转轴120向A方向转动。当动力单元180在B’方向拉动驱动单元100时，驱动单元100绕着转轴120向B方向转动。通过在A’方向和B’方向上交替拉动驱动单元100，可以实现驱动单元100绕着转轴120向A方向和B方向交替转动。
具体的，在本发明实施例中，动力单元180为形状记忆合金。形状记忆合金A’方向部分和B’方向部分被交替通断电，进而通过其长度的变化，对驱动单元100施加力的作用。动力单元180可以由一根连续的形状记忆合金构成，也可以由左右两段(如A’方向段和B’方向段)形状记忆合金组成，在这里并不做具体限制，只要能够满足施加力的作用进而使驱动单元100转动的条件即可。
在这里，需要说明的是，动力单元180包括但不限于形状记忆合金，在本发明的其它实施例中，动力单元180还可以是其他结构，而且动力单元180对驱动单元100施力的位置也不限于在驱动单元100的顶部位置140，只要能够满足对驱动单元100施加力的作用使驱动单元100左右交替转动的条件即可。
请结合参考图2a所示的驱动单元100立体结构示意图，驱动单元100还包括多于两个驱动臂110。驱动轮130包括多个子轮，子轮的圆周表面设置有 轮齿131(如下文图6和图7所示)。再结合图1和图2a所示的结构，当驱动单元100一侧设置多个驱动臂110，驱动单元100能够通过多个档位转动带动驱动臂110推动轮齿131，以使驱动轮130进行多档转动。因此，在本发明的实施例中，驱动单元100和驱动轮130是相配合使用的。在这里，相配合是指驱动轮130的位置、子轮的数目需要与驱动单元100的工作原理以及驱动臂110的数目、位置结构相适应。
如图1和图2a所示，在本发明的实施例中，多个驱动臂110分别设置于驱动单元100的两侧。因此，多个子轮也分别设置于驱动单元100两侧，以配合驱动臂110使用。具体的，在本发明实施例中，驱动单元100包括4个驱动臂110，分别为110a、110b、110c、110d。其中110a、110b设置于驱动单元100的一侧，110c、110d设置于驱动单元100的另一侧。驱动轮130包括两个子轮，一个子轮与110a、110b相配合，另一个子轮与110c、110d相配合。
这里需要说明的是，驱动轮130还可以包括多于两个子轮，如根据多个驱动臂110位置结构的设计，可以在驱动单元100一侧设置两个相邻的子轮，以配合位于驱动单元100该侧不同位置和数量的驱动臂110。
图2a、图2b和图2c分别为驱动单元100的立体结构示意图、侧视结构示意图和俯视结构示意图，且图2c的俯视方向为图2b中箭头所示的方向，图2b的侧视方向为图2c中箭头所示的方向。
在本发明的实施例中，位于驱动单元100一侧的两个驱动臂110呈上下设置。在这里，上下设置是指图2b中所示的上下位置关系表示。具体的，是指在侧视图图2b中能够看到驱动单元100一侧的两个驱动臂110(如110a和110b)，而在俯视图图2c中，110b和110d分别被110a和110c遮挡，如图2c中虚线表示的110b和110d。
在本发明的实施例中，由于驱动轮130为圆形，相邻轮齿被施加推动力的表面并不平行。因此为了在驱动时驱动臂110和轮齿推动面保持垂直，进而提高驱动臂110的推动效率，当驱动单元100一侧的驱动臂110推动轮齿131时，该侧的两个驱动臂110在推动方向所在的直线相交。具体的，如图2b所示，当轮齿131被110a和/或110b推动时，110a所在的直线为l 1，110b所在的直线为l 2，l 1和l 2的夹角为α，3.1°≤α≤4.1°。具体的，在本发明实施例中，α＝3.5°。在本发明的另一个实施例中，α＝3.3°。在本发明的又一个实施例中，α＝3.9°。
需要说明的是，在本发明的其它实施例中，根据不同的结构设计，当驱动单元100一侧的驱动臂110推动轮齿131时，该侧的两个驱动臂110在推动方 向所在直线还可以平行(α＝0°)或者异面，同样可以推动驱动轮130转动，达到输注药物的目的。此时，l 1和l 2的夹角α可根据实际的结构而设定，如α可根据驱动轮130的直径和数量、轮齿131的数目、螺杆170的节距以及驱动臂110的位置关系和数目而设定，如α还可以介于0°～3.1°之间或者4.1°＜α≤7°，在这里并不做具体限制。
如图2a和图2b的虚线圈10部位所示，在本发明实施例中，位于驱动单元100一侧的两个驱动臂110是在虚线圈10处经过翻折形成的。在本发明的其它实施例中，位于驱动单元100一侧的两个驱动臂110还可以通过其它方式形成，如图3a和3b所示的驱动单元立体结构示意图中，位于上方位置的210a、210c与下方位置的210b、210d分别设置于不同结构子单元中。如在图3a中，两个结构子单元通过焊接或其他的连接方式被固定在一起，成为一体结构。再如图3b所示，两个结构子单元在驱动单元300的顶部位置340处相连接，再将驱动单元300的顶部位置340经过翻折形成本发明实施例中驱动臂310的结构。
需要说明的是，在本发明的其它实施例中，驱动臂还可以通过其它的方式形成，只要能够满足推动驱动轮转动的条件即可，这里并不做具体限制。
请参考图4，为本发明另一个实施例的驱动单元400俯视示意图。
图4和图2c的视角相同。结合图2a、图2b、图2c和图4，明显的，驱动单元400一侧的两个驱动臂呈左右稍稍错位设置，如410a、410b以及410c、410d。具体的，在本发明的一个实施例中，410a和410c向右偏移，410b和410d向左偏移。
需要说明的是，在本发明的其他实施例中，同一侧的两个驱动臂的左右偏移量以及两者相对向哪一个方向偏移，需要根据实际结构设计而定，在这里并不作具体限制。进一步的，在本发明的一个实施例中，驱动单元一侧的两个驱动臂还可以左右设置。在这里，左右设置是指从如图4的视角下(俯视)，能够看到驱动单元一侧两个完整的驱动臂，同时从如图2b的视角下(侧视)，靠近驱动单元主体的驱动臂被远离驱动单元主体的驱动臂全部遮挡，或者部分遮挡，此时，驱动单元同侧驱动臂推动方向所在直线共面或者异面。同时，对驱动臂的长度以及不同驱动臂之间的长度关系不做具体限制。
请参考图5，为本发明又一个实施例的驱动单元500的立体结构示意图。
具体的，驱动单元500包括6个驱动臂510，每三个设置在驱动单元500的一侧，具体是：510a、510b、510c设置在一侧，510d、510e、510f设置于 另一侧。如前文所述，同样的，同一侧驱动臂510的长度、之间的长度关系以及位置设置均根据具体结构和工作原理而设计，在这里并不做具体限制。具体的，在本发明实施例中，驱动单元500同一侧三个驱动臂510的位置关系同图2a、图2b和图2c中的相似，即驱动单元500同一侧三个驱动臂510上下设置。
需要说明的是，在本发明的其它实施例中，驱动臂总数还可以是奇数个，如3个、5个或者更多，即驱动单元两侧驱动臂的数量不相等。而且不同驱动臂之间的结构关系可以和上文所述的类似，在这里并不做具体限制，
请结合参考图6和图2c，图6为驱动轮130的局部结构示意图，131为轮齿。
在图2c的视角下，驱动单元100一侧两个驱动臂驱动端的水平距离为h，轮齿131的齿距为s，则0.5s≤h≤1.5s。具体的，在本发明的实施例中，h＝0.8s。在本发明的另一个实施例中，h＝1.2s。在本发明的又一个实施例中，h＝s。在这里，驱动臂110的驱动端是指驱动臂110在推动时直接和轮齿131接触的一端。水平距离是指按照如图2c的角度俯视时，驱动单元100同侧两个驱动臂110驱动端之间的平面距离。
需要说明的是，在本发明的其它实施例中，还可以有0.1s≤h＜0.5s或者1.5s＜h≤2.5s，均可以实现本发明的效果，在这里并不做具体限制。
如图6所示，在本发明实施例中，驱动轮130为棘轮，轮齿131为棘轮齿。采用棘轮能够防止驱动轮130反转。每个棘轮齿齿面包括缓面和陡面，如图6所示。而且，在本发明实施例中，在驱动单元100单次向一个方向转动的整个过程中，驱动单元100的驱动臂110包括推动驱动轮130转动的部分和非推动驱动轮130转动的部分。推动驱动轮130转动的部分将推动力作用于棘轮齿的陡面实施推动，使驱动轮130向C方向转动。
请参考图7，为驱动单元100和驱动轮130相配合的立体结构示意图。
结合图7、图1、图2b和图2c，在本发明实施例中，在动力单元180的作用下，驱动单元100绕着转轴120转动，从而带动驱动单元100两侧的多个驱动臂110推动轮齿131，进而推动驱动轮130转动。
请结合参考图7和图8，图8为驱动单元100进行转动的多个档位的位置结构示意图。
如前文所述，驱动单元100同侧的驱动臂110驱动端之间具有一定距离h，在推动时其推动方向所在直线具有一定夹角α，因此，在驱动单元100单次向一个方向转动的整个过程中，如图7中单次向A方向转动，110a和/或110b 推动轮齿131使驱动轮130转动，而110c和110d可在轮齿131上滑动(如在棘轮齿的缓面上滑动，并不施加推动驱动轮130转动的力)。且明显的，110c先滑动到相邻的下一个齿上，并发出“哒”声。此时，110c的驱动端作用于棘轮齿的陡面，防止驱动轮130反转。此时驱动单元100可以停止转动，驱动臂110a和/或110b停止推动轮齿131，驱动轮130停止转动。驱动单元100完成了一个档位的转动，请参考图8，此时驱动单元100向A方向转动到A 1位置，即到达A 1档。下一刻驱动单元100继续向A方向转动，110d会滑动到相邻的下一个齿上，并同样发出“哒”声。同样的，110d的驱动端作用于棘轮齿的陡面，防止驱动轮130反转。驱动单元100又完成了一个档位的转动，请参考图8，此时驱动单元100转动到A 2位置，即到达A 2档。此时110c和110d各自完成一次相邻轮齿131之间的滑动，驱动单元100完成了单次向A方向转动的整个过程，实现A 1、A 2两档位转动，从而对驱动轮130进行两档位推动，使得药物输注装置进行两档位输注。
需要说明的是，在上述转动过程中，还可以是110d先滑动至下一个轮齿131，110c后滑动至下一个轮齿131，在这里不作具体限制。同样的，当驱动单元100向B方向转动时，同样有B 1、B 2两档位的转动动作。
明显的，驱动单元100在上述单次向A方向转动的整个过程中，驱动单元100经过了转动和停止转动相交替的动作，驱动臂110交替地推动和停止推动轮齿131，使驱动轮130交替地转动和停止转动，实现了对驱动轮130的两档位推动，最终达到两档位药物输注的目的。
具体的，当驱动单元100一侧具有两个驱动臂110时，驱动单元100在单次向A方向转动的整个过程中，驱动单元100经过转动-停止转动-转动的两档位动作，实现对驱动轮130的两档推动。当驱动单元100一侧具有三个驱动臂110时，驱动单元100在单次向A方向转动的整个过程中，驱动单元100经过转动-停止转动-转动-停止转动-转动三档位动作，实现对驱动轮130的三档推动，完成三档输注。以此类推，当驱动单元100一侧具有更多个驱动臂110时，驱动单元100通过旋-停-旋-停-旋-…-旋的多档位动作实现对驱动轮130的多档推动，完成多档输注。
请继续参考图7，结合上文所述，在本发明的实施例中，当驱动单元100推动驱动轮130转动时，实施推动力一侧的驱动臂110中至少有一个驱动臂110对轮齿131施加推动力。而另一侧的一个或两个驱动臂110与轮齿131接触，但并不对轮齿131施加使驱动轮130转动的力，只是会在某时刻提供防止 驱动轮130反转的力。因此，本发明实施例存在一种情况：驱动单元100的所有驱动臂110中只有一个驱动臂110对轮齿131施加推动驱动轮130转动的力，其他的驱动臂110会和驱动轮130接触，而并不对轮齿131施加推动驱动轮130转动的力。且此时，另一侧在轮齿上滑动的驱动臂110会对轮齿131施加防止驱动轮130反转的力。
需要说明的是，对于在驱动单元100一侧有三个甚至更多个驱动臂110的本发明实施例中，驱动单元100工作时，也会有上述类似的情况。当驱动臂有奇数个时，驱动单元两侧的驱动臂数量不相等，驱动单元在向某一方向转动的整个过程中，也会有上述同样的过程。
请继续参考图8，在本发明的另一个实施例中，当驱动单元100一侧具有两个驱动臂110时，驱动单元100向A方向转动一个档位，即到达A 1档后，转而向B方向转动一个档位或两个档位，即到达B 1档或B 2档，直至向B方向的转动停止。此过程为驱动单元100完成了一次向两个方向的交替转动，从而可对驱动轮130实施多档推动。因此，本发明实施例中，驱动单元100可以在A 1-B 1档位或A 1-B 1-B 2档位或B 1-A 1-A 2档位之间交替切换档位进行转动，达到切换不同档位进行输注的目的。
继续参考图8，在本发明的又一个实施例中，驱动单元100还可以直接转动到A 2档位，而不经过A 1档位。然后再直接转动到B 2档位，而不经过B 1档位，即驱动单元100直接在A 2-B 2档位之间交替转动。如上所述，驱动单元100还可以在A 1-B 1档位之间交替转动。明显的，在单位时间内，驱动单元100在A 2-B 2档位之间交替转动时的药物输注量大于其在A 1-B 1档位之间交替转动时的药物输注量。如果最小档输注的药物量为该药物输注装置的最小药物输注量，那么利用本发明实施例的药物输注装置能够降低最小药物输注量，实现对药物输注的精确控制。当患者需要输注较多药物时，可选择大档位A 2-B 2档位模式，加快输注速率。当需要输注少量药物时，患者可以选择小档位A 1-B 1档位模式，降低药物输注速率，实现对药物输注的精确控制。
在一种药物输注系统中，驱动单元两侧分别只设置有一个驱动臂，单次向一个方向转动的整个过程中，只能对驱动轮实施一档推动，如图8中只能在A 2-B 2之间交替推动。该一档推动方法不能够灵活控制药物输注量和输注速率。同时，最小药物输注量较大，不能精确控制药物输注，最终会导致患者体液水平波动较大。同时也是对药物的一种浪费，增加了患者的成本。
与具有一个档位输注的装置相比，本发明实施例药物输注装置通过在驱动 单元上设置多于两个驱动臂实现对驱动轮的多个档位推动，进而达到多档位药物输注的目的。利用本发明实施例的药物输注装置，患者可根据实际输注量以及输注速率的需求，自由灵活地切换不同的输注档位，提高了输注效率。同时，在大档位A 2-B 2档位之间设置中间档位A 1-B 1-B 2档位或B 1-A 1-A 2档位，以及小档位A 1-B 1档位，药物输注装置能够降低最小药物输注量，达到精确控制输注的目标。
如利用本发明实施例的药物输注装置，在开始输注时，药物输注量比较大，患者可以选择图8所示的大档位A 2-B 2档进行输注。输注一段时间后，可改用中间档位A 1-B 1-B 2档或B 1-A 1-A 2档，降低药物输注的速率。当接近完成药物输注时，患者可选用小档位A 1-B 1档位输注，进一步降低输注速率，达到对药物输注的精确控制。当然，患者还可以选择其中某一个或某几个档位进行输注，这里并不做具体限制。
在本发明的其它实施例中，当驱动单元100的一侧设置多于两个驱动臂110时，药物输注装置可具有更多且更加精细的输注档位，患者可以进一步灵活控制输注过程，更加精密地控制输注。
综上所述，本发明公开了一种药物输注装置，在驱动单元上设置多于两个驱动臂，驱动单元通过多个档位的转动对驱动轮进行多档位推动，进而实现了对药物的多档输注，增加了患者对输注过程控制的灵活度，提高了药物输注效率。同时药物输注装置也减低了最小药物输注量，患者能够精确控制药物输注，精密管理自身的生理状况。
虽然已经通过示例对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
