Description

输注泵和原位测量输注管子的直径的方法
背景技术
本发明的领域为输注泵，并且一般地涉及用于典型地经静脉内线路对患者泵送或输注医用流体容积的系统、设备和方法。
输注泵用来典型地经静脉内线路向患者输注药物和液体。虽然一些输注泵处理相对较大的容积，但可能更关注能够仅递送非常小受控容积的液体的泵。所用药物可以是非常重要的，例如止痛药、包括鸦片剂在内的麻醉剂、抗炎剂、胰岛素、镇挛药、抗生素、化疗剂、心血管药物等。许多此类药物需要以非常低的剂量连续供给，以使得长时间内为患者供给稳定可靠的流，例如每小时0.1ml。如果使用脉冲，则可以测量按每脉冲或每次推注的纳升或微升数测量的剂量率。不论使用小容积泵或较大容积泵，泵的精度可以为患者带来成功的结果。
一些输注泵沿管子长度具有带有入口阀和出口阀的增压室。输注流体通过打开的入口阀接收到增压室内一段长度的管子内，然后通过关闭管子入口处的入口阀封闭管子以隔离输注流体。然后，打开出口阀，泵送机构压缩或以其他方式按摩所关注的一段管子，以将流体从增压室泵送或排向患者。由于入口被关闭的阀门堵塞，液体只能经阀门打开的出口流出。然后，关闭出口阀，并打开入口阀和泵送机构，以允许另外的流体从流体源进入增压室。上述过程被称为单个泵送周期或冲程。
泵送机构可包括将管压靠静止的块体或压板的单个泵送构件。在这种情况下，泵送构件或压板可具有基本上与入口阀和出口阀之间长度类似的长度。替代地，泵送机构可包括按序压缩管子的多个泵送指状物或构件。在这种情况下，尤其是在有足够的泵送指状物，使得任何时候都至少有一个指状物压缩管子的情况下，可能不需要入口和/或出口阀。
总体输注精度取决于每个泵送周期的精度。换句话讲，重要的是准确地知道每个泵送周期泵送的流体容积，以了解随时间推移的全部输注容积。每个泵送周期的容积取决于管子的内径。问题出自管子与管子的内径差异。除了别的原因以外，这种差异由制造工艺和公差所造成。有利的是，使得输注泵能够确定或测量用于具体输注的具体IV管的内径。基于此信息，泵能够调节泵送机构的功能(泵送机构的速度和冲程长度)，以无论管子内径差异如何都能确保和维持精度。
另外，泵能够利用该信息避免过度压缩管子(因过度应力而缩短管子寿命)和管子欠压缩(导致不精确和效率低下)。
输注泵用来为患者准确输注药物和其他液体。通过准确了解用来为患者分配具体液体的具体管子的内部尺寸，可以改进所分配的量。
发明内容
本公开包括可为患者递送指定量的药物，例如胰岛素或吗啡，的输注泵。该泵准确递送指定量的正确药物，从而确保患者达到最佳的可能效果。该泵使用管子，尤其使用接触长度的管子，来操作，以将来自诸如静脉注射(“IV”)容器的源的药物经接触长度输送，以使得药物不接触空气，从而避免患者接触污染物。典型地，通过将塑性材料从模具中挤出来制备管子。所得管子的尺寸，例如内径或外径，可以变化多达百分之三或四。本发明的泵通过确定管子在使用过程中的接触部分的实际尺寸克服了这个问题。
输注泵使用至少一个传感器工作，该传感器测量将管子保持在接触区域的物理约束物之间的距离。物理约束物可包括静止的表面或压板和运动的表面或压板，管子在该二者之间压缩和减压。具体地讲，一种方法和相应的系统包括以下步骤：将管子加载到夹具；在夹具的相对表面之间压缩管子；在压缩的同时接收指示管子压缩的信号；接收指示管子抵靠相对表面中的至少一个的接触长度的信号；以及计算管子的直径和厚度。
另一种方法和相应的系统包括以下步骤：将管子加载到夹具；在夹具的相对表面之间压缩管子；在压缩的同时产生并接收指示相对表面之间的距离的信号；产生并接收指示管子抵靠相对表面中的至少一个的接触长度的信号；以及计算管子的内径和厚度。
上述方法和系统尤其适用于输注泵。输注泵包括：管子夹紧段，所述管子夹紧段具有活动部分和静止部分；第一传感器，所述第一传感器安装在活动部分或静止部分中的一个上，用于检测活动部分和静止部分之间的距离；至少一个第二传感器，所述至少一个第二传感器用于检测管子与活动部分和静止部分中的至少一个的接触长度；入口阀；出口阀；以及滑阀，所述滑阀具有滑阀静止部分和滑阀活动部分，被构造用于挤压滑阀静止部分和滑阀活动部分之间的一段长度的管子，其中滑阀活动部分朝着和远离滑阀静止部分移动，以操作输注泵。
替代性地，输注泵包括：壳体；管子夹紧段，所述管子夹紧段具有活动部分和静止部分，并且安装在壳体上；第一传感器，所述第一传感器安装在活动部分或静止部分中的一个上，用于检测活动部分和静止部分之间的距离；至少一个第二传感器，所述至少一个第二传感器用于检测管子与活动部分和静止部分中的至少一个的接触长度；以及正排量泵，所述正排量泵用于操纵管子以准确递送药物。
因此，本发明的一个优点是提供一种系统和方法，该系统和方法用于在确定经管式泵泵送的药物流体容积时补偿管子制造变差。
本发明的另一个优点是提供一种系统和方法，该系统和方法用于在确定经管式泵泵送的药物流体容量时补偿管子加载变差。
另外的特征和优点将在本文中有所描述，并且从以下具体实施方式和附图中将显而易见。

具体实施方式
现在参见附图，具体参见图1，图中示出了本公开的滑阀式输注泵50的一个实施例。输注泵50包括管子16、入口阀52、出口阀53和具有上活动压板12与下静止压板14的滑阀部分10。阀门52和53及滑阀部分10分别由线性致动器54a至54c致动。泵控制器100可与输注泵50的其他处理器诸如监控处理器和安全处理器(未示出)一起工作，控制泵50及其线性致动器54a至54c。
为了泵送流体，致动器54a打开入口阀52。致动器54b关闭出口阀53，以及致动器54c回缩压板12，以允许管子16打开以例如通过重力接纳液体药物。接着，致动器54a和54b分别使阀门52和53的状态反转，致动器54c将压板12推向压板14以压缩管子51，从而排出刚好充盈压板12和14之间的管子51的流体容积。
如下文详细描述的，传感器18、19(例如传感器对)嵌入到活动压板12和静止压板14内。发射机18可以附接到活动压板12，而接收机19则附接到静止压板14。使用过程中，当滑阀活动压板12关闭管子51以泵送待输注入患者体内的液体时，发射机18和接收机19分别发送和接收信号并检测该对之间的距离，下文将详细讨论。与此同时，如下文所讨论的，由多个传感器构成的传感器阵列24检测与压板12和14接触的管子段的长度。以此方式，传感器18、19和传感器阵列24检测和测量管子的压缩距离和接触长度，并将这些数据发送至控制器100，以计算实际泵送的溶液的准确体积。可以对各个泵送冲程重复这种感测。泵控制器100接着对准确确定的体积合计，以调节活动压板12的移动频率和/或距离，从而确保精度。
现在参见图2，高层级流程图示出了由控制器100为本文所述多个实施例进行的算法或工艺流程图的一个实施例。该过程的第一步骤101是将管子加载到上述滑阀部分10。加载之后，在步骤102中将管子在具有传感器的两个相对表面之间压缩，其中传感器测量两表面之间的距离以及测量管子与至少一个表面之间的接触长度。在进行测试的同时，控制器100在步骤103中监视传感器的信号输出变化。如步骤104所示，当信号几乎没有变化时，可以停止表面的移动。接着，在步骤105中记录信号，并且如步骤106所示，控制器100进行计算，以确定管子的接触长度、管子的厚度以及管子的内径和外径。然后，控制器100使用上述实际尺寸计算实际泵送的液体体积，并调节未来的泵送(例如冲程频率)，以使所泵送流体的实际总体积等于目标总体积。
现在参见图3A和3B，图中更详细地示出了图1的输注泵50的滑阀部分10，该滑阀部分包括下静止压板14和上活动压板12，两压板与管子16一同工作。在所示实施例中，下压板14平行于上活动压板12。管子16通常为PVC，但也可以由聚乙烯、聚丙烯、另一种医学上可接受的塑料、或它们的组合制成。在图3A中，压缩之前，当初始置于滑阀部分10内时，管子16具有管子厚度t和外半径R0。
如图3B所示，当活动压板12闭合时，管子16被压缩。在图3A和3B中，d为上压板12和下压板14之间的距离，r为连续变化的管子曲线的半径，并且其中管子与压板分离的点限定了管子与压板的切向接触距离。如管子16左侧和右侧的箭头所示，管子的长度l限定了与上压板12和下压板14的该接触距离，并且其中l的边缘限定了切向释放点。
现在将解释图3A和3B中所示公式。管子16侧面的连续变化曲线从管子接触下压板14和上压板12的接触长度延伸，该两个压板彼此平行。因此，新形成的曲线为具有半径r的半圆形，该半径等于压板之间的距离d的一半。每个新形成的半圆的曲线长度等于πr，两个半圆或端部的总长度为2πr。结合图3A所示公式表示以下涵义：管子16的总外部曲线长度在压缩过程中不变，总外部曲线长度等于管子16为圆形形状时的周长2πR0。当管子被压缩至图1的右手部分所示位置时，总外部曲线长度等于两个新形成的半圆的长度2πr(或πd)+接触长度l的二倍。要求解管子的实际半径R0，可知R0为d/2+l/π。在图3A中，管子16刚好与压板12和14相切。在这种情况下，两压板之间的距离d正好为管子16的外径2R0。因此，接触长度为零，该长度的二倍2l也为零。因此，管子的周长为测量的距离d即直径的π倍，等于2πr，或者在这种情况下为2πR0。管子平面内的面积为内半径的平方的π倍，并且用该面积乘以管子的长度或被输注泵推进的液体的长度来计算体积。
要使用该方法测量管子的直径，理论上可以将管子压缩至任何位置。如图3B的公式框2中所示，接触长度l1、l2取自两个不同的距离d1和d2处。接触长度l1和l2的差值与压缩步骤中压板距离d的差值成比例。利用这些对应值，使用压板距离d的变化，可以确定接触长度l的变化。此外，当使用该方法测量管子直径时，通过将管子压缩至很多不同位置，可以进行多次测试，然后使用所有计算值的平均值来获得更准确的值。
图4A至4C示出了一种典型情形，其中，在活动的泵压板12闭合时，压缩管子16，并抵靠下固定压板14挤压管子16。压板12和14之间的距离d用超声波传感器(传感器对18和19)测量，在该实施例中，传感器对具有位于顶部压板12处的发射机18和位于底部压板14处的接收机19。许多输注泵已经包括用作空气混入(air-in-line)传感器的超声波传感器。这种常常预先存在的传感器可以用作输注泵50的传感器18和19(图1)。其他实施例可以使用电容式传感器、诸如线性可变差动变压器(“LVDT”)的线性传感器或其他距离测量传感器。如图4B所示，当上压板12下降时，管子16变平至距离d。
如图4C所示，当活动压板12完全下降时，管子16压缩，使得压板12、14仅被管子16本身隔开，并且距离d为管壁厚度t的二倍。控制器100可利用传感器18、19来查看距离d不再变化，并且确定管子16如图4C所示被完全压缩。甚至在完全压缩之前，距离传感器18、19仍然显示，当压板12和14彼此非常靠近，压板之间仅被管子本身的厚度隔开，管子内没有空气或液体时，距离d非常缓慢地变化。如结合图1所述，致动器54c向上压板12施加力，以将该压板闭合抵靠固定压板14。可以还或替代性地设置力传感器，并观察力的增加，以通过信号指示图4C的完全压缩。可以还或替代性地监视致动器54c的功率或电流消耗，以观察电流消耗的增加值，并指示是否完全压缩。
如图5A和5B所示，还存在确定行进距离或管子压缩量的进一步的替代方式。如上所述，滑阀部分10包括活动的上部或压板12、底部压板14和管子16。然而在此处，压板12是由具有编码器22的马达20(如线性)推动。马达可包括导向螺杆、滚珠螺杆、起重螺丝等，用来将旋转运动转化为平移运动，以抵靠管子16移动压板12。马达20和编码器22连接到如上所示控制器100，其提供可供控制器100使用并转化为速率信息的位置信息。控制器100控制马达20并记录来自编码器22的数据，该数据与马达20的轴的位置有关，并将该位置或位置变化转化为压板12的平移位置变化的准确计算值。从已知位置开始，利用来自编码器的信息，并跟踪管子16压缩过程中许多个离散时间段的记录距离d，可以在任何时间确定压板12的行程和位置。
图5A、5B和6示出了传感器阵列24。传感器阵列24包括相隔距离l的至少两个传感器26。如图6所示，可以存在至少两个传感器26的一个或多个列或行，每个行或列相隔距离1，该距离可以相同或不同。对于许多应用来说，单行的两个传感器26可能已经足够。两个传感器26检测传感器26之间是否存在管子16。当管子16不再接触传感器26时，传感器26不会指示管子存在。当管子与压板12和14之间只有相切接触点时，可能会出现这种情况。传感器26之间的距离l可以设置为这样的长度：当压板之间的距离d为2t时，管子边缘刚好接触传感器。对于具有已知内径、外径和壁厚的给定的管子构型，当存在已知的管子压缩量，管子长度达到长度l，管子厚度为约2t时，压板12和14将隔开距离d。为了设定距离l，可以进行测量，并利用校准数据点以测量当压板相隔距离d且接触压板的管子16具有厚度2t时管子接触压板和传感器的长度l。
当管子压靠滑阀部分10的压板12和14时，阵列24的传感器26能够检测到管子的存在。例如，可以使用小的紧凑型压力传感器、电容式传感器或电感式传感器。传感器26检测是否存在如上所示管子16的弄平部分。当管子仅仅与压板相切接触时，传感器26将停止检测是否存在管子16。例如，当管子16接触压力传感器26时，该压力传感器将显示压力的快速升高或急剧上升。当移除压力时，压力的下降和压力信号也会同样迅速。电容式传感器26将以类似方式工作，当管子接近电容式传感器例如间隔开已知距离l的两个电容式传感器26时，快速检测管子材料，尤其是湿材料。
除了上面示出的传感器阵列24之外，存在可用来检测接触长度和管子压缩量的其他方法。图7A和7B示出同样具有静止压板14、活动压板12和一段长度的输注泵管子16的滑阀部分10。在所示实施例中，在顶部或活动压板12上安装有电容式传感器30，而在下方的、静止压板14上安装有标靶32。当顶部压板12下降到位以挤压管子16时，电容式传感器30检测底部压板14上的标靶32。使用传感器30对泵50(图1)进行校准使得利用电容式传感器进行准确检测成为可能。应当认识到，在该构型中，可以使用其他接近传感器，例如电感式和超声波传感器。此类接近传感器较小，并且相对于输注泵50(图1)的操作不突出(unobtrusive)。标靶32同样不突出。例如，标靶32可以只是模铸到压板14或位于活动压板12的输注泵50的本体的其他部分内的金属小珠或方块。
图8A和8B示出了用于确定接触长度和距离的另一种设备和方法。这里再次，滑阀部分10包括接纳圆形塑性管子16的顶部压板12和底部压板14。顶部压板12装有两种传感器，即接近传感器34和两个微动开关36。底部压板14装有用于接近传感器34的匹配感测对象38。当接近传感器34为例如电容式传感器时，感测对象38为适于被电容式传感器检测的标靶，例如，薄金属板或导电区域。当底部压板14为金属时，电感式或电容式传感器可以在没有独立标靶的情况下感测压板14本身。
顶部压板12也包括两个微动开关36。微动开关为小型限位开关，当管子16的接触部分靠近(管子闭合)或离开(管子打开)顶部压板12的底部表面时，该开关被触发。因此，微动开关36的操作类似于上述传感器阵列24，其中微动开关之间的距离用作传感器阵列的距离l。作为另外一种选择，也可以使用线性可变差动变压器(“LVDT”)，有时也称为线性电压位移变压器，来确定压板12和14之间的距离d。
结合以上附图描述的多种传感器的样品读数结合图9至11进行了讨论。在图9中，使用接近传感器以感测活动压板12向着静止压板14的靠近。这种靠近可以是非线性的，并且示出有点非线性的信号。然而，当两个压板非常靠近时，该信号趋于非常小地变化。也就是说，距离变化非线性地降低至距离24，并且其在2t和假想的零距离之间保持稳定。因此，控制器100可以被构造为观察距离变化或Δd变为零，以确定管子16被完全压缩。因此，在一个实施例中，当接近传感器信号强度被稳定在某个量或百分比内时，推断为距离2t。该模式对于例如电容式传感器、电感式传感器、超声波传感器适用。
在图10中，公开了压力传感器的读数。在该实施例中，压力传感器，例如作为传感器阵列24的一部分，读数为零值，如图所示，该值在切点d＝2r(图3B)处上升至非常小的值。当压板12继续闭合时，随着管子从d＝2r压缩至d＝2t，压力升高，直到当距离达到2t(管子被压平)时，压力出现非常快速的升高。
图11示出微动开关的读数，当管子压缩触点时，该开关将根据需要接通或关闭。在图示情况下，开关正常接通，并且当压板12闭合时，开关保持接通，并发出稳定的信号，直到达到切点(d＝2r)时，开关关断。接着，开关在d＝2r和d＝2t之间，甚至经过点2t处，保持关闭，直到压板12打开和微动开关复位。
本公开还包括管子16不刚好位于滑阀部分10中央的情形。例如，图12A示出管子16向左偏移距离Δd的上压板12和下压板14。传感器26a和26b(如压力传感器)将注意到这种偏移。图12B示出，相隔距离l的两个压力开关26a和26b的阵列24获取不同时间的压力。在这种情况下，管子16偏向左侧，而左侧的第一压力传感器26a首先检测压力，其压力检测时间和距离不同于由右侧的传感器26b所检测的压力。在图12C中，当使用如图8A和8B所示的两个针型(pin-type)微动开关时，左侧开关36在右侧开关36跳脱之前被管子跳脱。在这种情况下，真实的管子接触长度将等于l+Δl，其中l为两传感器之间的距离(图12A)，Δl为因时间差引起的额外接触长度，该时间差为左侧第一传感器检测到压力和右侧第二传感器检测到压力之间的时间差，如图12D所示。管子接触压板的额外长度为Δl。根据第一和第二压力传感器检测到压力急剧上升的时间差，可以测量压板距离的差值Δd。然后，使用Δd计算Δl，如图12D所示。利用总管子接触长度l+Δl和压板之间的距离，可以计算管子直径。当然，如果存在偏移引起的延时，则距离变化Δd将与接触长度变化Δl反转。
现在参见图13，图中示出使用线性蠕动泵60进行替代操作的本公开的管子直径检测。输注泵60包括马达61、驱动轴62和用于将泵杆64压紧抵靠管子65的多个凸轮板63。致动器64压紧抵靠静止部分66，从而在杆之间连续挤压输注液。输注泵60还包括另外的凸轮板67。在该实施例中，泵控制器100控制马达61，分离凸轮板67，并从接近传感器69接收信号。在输注泵的控制器的命令下，凸轮板67包括接近传感器69。当凸轮板被向前推动时，接近传感器69感测静止部分68内的标靶70，该标耙70可以是静止部分66的一部分，或者可以不同。静止部分68包括用于感测管子65抵靠静止部分68的接触长度的长度传感器71。微处理器控制器100接收来自传感器69和71的信号并控制马达61、凸轮板67和输注泵的其他部分。
微控制器100还具有存储器，或者能够访问存储器，用于计算机可读介质上的计算机程序，以保存上述公式和如上文所述计算管子的接触长度和直径。根据这些读数和计算，控制器100计算已经递送给患者的药物或输注液的体积。
应当理解，本文所述优选实施例的各种变化和修改对于本领域的技术人员将显而易见。在不脱离本主题精神和范围且不减少其预期优点的情况下，可以进行这些变化和修改。因此，旨在由所附权利要求涵盖这些变化和修改。
