相关申请
本申请要求号为62/655,516的、2018年4月10日提交的美国临时专利申请的权益，其通过引用以其整体并入本文。
技术领域
本公开涉及用于将药物输送给患者的医用泵，更具体地涉及用于将诸如胰岛素的药物输送给患者的用户可佩戴的输注泵。
背景技术
在学术、工业和医学领域中存在许多应用，这些应用受益于能够准确地和可控地输送流体(例如液体和气体)的设备和方法，当以已知和受控的数量施用时，所述设备和方法具有有益效果。这种设备和方法能够在医疗领域中特别有用，在该领域中，对许多患者的治疗包括以预定的时间间隔施用已知量的物质。
用于输送这种流体的一类设备是泵，该泵已经被开发用来为患有I型和II型糖尿病的患者施用胰岛素和其它药物。被配置为便携式输注设备的一些泵能够为糖尿病的治疗提供连续皮下药物注射和/或输注疗法。这种疗法可以包括，例如，将胰岛素定期和/或连续注射或输注到患有糖尿病的人的皮肤中，并且提供了通过胰岛素注射器或胰岛素笔每日多次注射胰岛素的替代方案。这种泵能够是由用户佩戴的非固定的/便携式输注泵，并且可以使用可替换的药筒。这种泵和能够与这种泵相关联的各种特征的示例包括在公开号为2013/0053816的美国专利申请、号为8,573,027的美国专利、号为8,986,253的美国专利、公开号为2013/0324928的美国专利申请、公开号为2013/0331790的美国专利申请、号为8,287,495的美国专利、序列号为15/241,257的美国专利申请(提交于2016年8月19日)以及序列号为15/158,125的美国专利申请(提交于2016年5月18日)的中公开的那些，其中每一个通过引用以其整体并入本文。
许多非固定输注泵由需要定期再充电的电池供电。这通常通过将电缆的连接器插入到输注泵上的、有助于电力和/或数据的传送的端口(例如USB或类似端口)中，并且将电缆的另一端塞入到壁装插座或其他电源中来实现。近来，已经开发了许多消费设备，这些消费设备利用电磁感应来对设备的内部电池充电，而不需要额外的物理电子连接。在这样的系统中，充电基座内的传输感应线圈产生交变电磁场。当设备中的接收感应线圈与传输感应线圈对准时，电力被传送到用来对电池充电的设备中。利用感应充电的便携式输注泵的实施例在公开号为2016/0339172的美国专利和号为15/868,461的美国专利申请中公开，其中每一个通过引用以其整体并入本文。
实现感应充电，尤其是诸如非固定输注泵的医疗设备的挑战之一是，无线充电可能导致诸如金属的导电材料中的不需要的发热。这种发热是由金属中产生的涡流的电磁感应引起的。特别是在充电系统的传输和接收线圈没有最佳对准时，过度发热会成为问题。不需要的发热对于诸如智能电话的典型的消费电子设备并不是问题，但会对医疗设备造成问题。例如，诸如胰岛素的药物是温度敏感的，并且如果暴露于高温，则可能降解和/或变质。因此，存在这样的可能性，即，当设备通过这种过度发热进行感应充电时，输注泵中的胰岛素或其它药物可能变质或以其它方式变得无效或甚至危险。如果泵的用户或护理者现在意识到泵的内部中的胰岛素已经受到这种影响，尤其是如果泵的外部或其电路或其它内部部件尚未经历损坏，则这种可能性会特别麻烦。
发明内容
公开了方法和系统，其中，在诸如非固定输注泵的设备的感应充电期间，监测该设备中的温度，使得诸如胰岛素、特定电路和/或其它部件的温度敏感的内容物或部件不被损坏。在感应充电期间，能够在一个或多个位置处监测设备中的温度。如果温度违反一个或多个预定阈值和/或以大于一个或多个预定阈值的速率上升，则能够暂停充电或以降低的功率提供充电，以防止温度进一步上升并损坏设备的内容物和/或组件。与这些事件相关联的一个或多个警报也可以被触发，使得用户知道该情况并且可以采取校正动作。
在一个实施例中，一种方法包括检测被配置为包含药物并具有可再充电电池的非固定输注泵已被放置在感应充电设备上，并且利用所述感应充电设备、通过以第一充电速率对所述非固定输注泵传输电力来启动对所述非固定输注泵的所述可再充电电池的充电。在充电期间，当以第一充电速率对非固定输注泵传输电力时，能够检测非固定输注泵内的多个温度值。能够将非固定输注泵内的多个温度值与药物敏感阈值温度进行比较，在该药物敏感阈值温度下，被配置为包含在非固定输注泵内的药物能够变得受该温度负面影响。如果非固定输注泵内的多个温度值中的温度值低于药物敏感阈值温度，则感应充电设备能够继续以第一充电速率对非固定输注泵传输电力。如果非固定输注泵内的多个温度值中的温度值高于药物敏感阈值温度，则感应充电设备能够将第一充电速率降低到低于该第一充电速率的第二充电速率。
在一个实施例中，非固定输注泵系统能够包括非固定输注泵、感应充电设备以及一个或多个处理器，该非固定输注泵包括可再充电电池并且被配置为包含药物，该感应充电设备被配置为对非固定输注泵传输电力以对该非固定输注泵的可再充电电池充电。该系统能够被配置为检测非固定输注泵已被放置在感应充电设备上，并利用感应充电设备、通过以第一充电速率对非固定输注泵传输电力来启动对非固定输注泵的可再充电电池的充电。在充电期间，当以第一充电速率对非固定输注泵传输电力时，能够检测非固定输注泵内的多个温度值。能够将非固定输注泵内的多个温度值与药物敏感阈值温度进行比较，在该药物敏感阈值温度下，被配置为包含在非固定输注泵内的药物能够变得受温度负面影响。如果非固定输注泵内的多个温度值中的温度值低于药物敏感阈值温度，则感应充电设备能够继续以第一充电速率对非固定输注泵传输电力。如果非固定输注泵内的多个温度值中的温度值高于药物敏感阈值温度，则感应充电设备能够将第一充电速率降低到低于该第一充电速率的第二充电速率。
以上概述并非旨在描述本发明主题的每个说明性实施例或每个实施方式。下面的附图和详细描述更具体地举例说明了各种实施例。
附图说明
结合附图考虑各种实施例的以下详细描述，可以更完整地理解本发明的主题，其中，
图1A-1C描绘了根据本发明的实施例一种泵系统。
图2A-2D描绘了根据本发明的实施例的用于对泵系统的电池进行感应充电的程序。
图3描绘了根据本发明的实施例的用于对医疗设备进行感应充电的方法步骤的流程图。
虽然各种实施例可接受各种修改和替代形式，但其细节已通过附图中的示例示出并且将详细描述。然而，应当理解，目的并不是将所要求保护的发明限制于所描述的特定实施例。相反，目的是涵盖落入如权利要求书所限定的主题的精神和范围内的所有修改、等效物和替代方案。
具体实施方式
图1A-1C描绘了根据本发明的实施例的包括泵102的泵系统。泵102的驱动单元118包括驱动机构122，该驱动机构与泵102的一次性药筒116中的凹部配合，以将药筒116附接到驱动单元118，并通过套管从药筒116向用户输送诸如胰岛素的药物。根据本发明的实施例的泵系统能够包括泵102，该泵包括驱动单元118和药筒116以及任意另外的部件，例如输注器。一小段管道153能够从药筒116延伸，其中连接器152设计成附接到这种输注器的对应连接器，该输注器包括从对应连接器延伸到输注部位的一段管道，该输注部位具有输注部位连接器以将药物输送到输注部位。关于这种泵的进一步细节能够在2015年5月18日提交的、号为14/707,851的美国专利申请和公开号为2016/0339172和2017/0049957的美国专利中找到，其中每一个都通过引用以其整体并入本文。
在一个实施例中，泵102包括一个或多个处理器，该一个或多个处理器控制泵的操作，并且在一些实施例中，可以从一个或多个单独的设备接收信息和/或命令。这样的单独的设备能够包括例如专用远程控制或智能电话或执行应用的其他消费电子设备，该应用被配置为使得设备能够将操作命令传输到泵102的处理器。其他单独的设备可以包括例如连续葡萄糖监测器(CGM)、智能笔或被设计成提供关于用户的血糖值的信息或关于用户的其他相关信息的其他设备。在一些实施例中，处理器还能够将信息传输到一个或多个单独的设备(例如，智能电话、智能手表、膝上型或个人计算机、台式计算机、CGM等)，例如与设备参数、警告、提醒、泵状态等有关的信息。
参照图2A-2D，根据本公开的实施例的泵能够包括在泵驱动单元118中和/或与其相关的一个或多个可再充电电池。在一些实施例中，可再充电电池能够由例如感应充电板180感应充电。如图2B中所描绘的，在一些实施例中，充电板180能够包括具有切口的盖子182，该切口的尺寸被设计为容纳泵102，以便在再充电期间将泵102适当地定位并保持在充电板180上。在一些实施例中，如图2A、2B、2D中所示，充电板180可以通过连接到壁装插座来接收电力。在其它实施例中，充电板180可以另外地或可替代地包括到例如计算机(例如，经由USB)、12伏汽车插座、电池组(例如，经由USB)和太阳能电池板等的电源连接。
为了对泵102充电，泵102可以首先与输注器的管道断开(如图2C中所描绘的)。之后能够将该泵放置在充电板180上(如图2D中所描绘的)，当板180连接到电源时，将对其电池自动感应(再)充电。在另一个实施例中，在对电池再充电的同时，泵102能够保持连接到输注器和用户。在一些实施例中，能够感应充电的泵不包括连接件，例如USB端口，电源线能够插入到该连接件中来进行电力传送。这种实施例提供了优点：由于没有裸露的电接触而使得针对防水更稳健并且避免了施加在这种连接件上的电隔离要求。
对泵102的感应充电能够根据已知标准，例如Qi标准来执行。在这样的系统中，泵102和充电板180二者都包括感应线圈。连接到电源的充电板180中的传输线圈生成振荡磁场，该振荡磁场在泵102中的接收线圈中感应出交流电以将电力传送到泵102。在一个实施例中，充电板180连续地或周期性地(例如，每秒两次)发送模拟信号以检测泵102的存在。当板检测到泵的存在(经由磁负载)时，其将数字通信信号发送到，例如，与泵102相关联的处理器。泵处理器接收信号并且引导和/或发送返回信号到板180，这使得板180将充电功率传输到泵。
如上所述，当对设备的电池充电时，这种感应充电可能导致这些设备的不需要的发热。这个问题对于包含一个或多个热敏元件、部件或内容物的设备尤其重要，例如医疗设备，该医疗设备包括例如输送一种或多种诸如胰岛素等热敏药物的非固定输注泵。因此，本发明的实施例结合了一个或多个温度传感器，以监测诸如输注泵等医疗设备中的内部温度，并且能够基于检测到的温度来改变和/或暂停感应充电。
例如，在胰岛素的情况下，众所周知，胰岛素稳定的临界温度约为37摄氏度。因此，该系统可以设置阈值温度，例如35摄氏度，在该阈值温度或高于该阈值温度时，将采取和/或指示改变感应充电的动作以防止胰岛素达到37度。在一个实施例中，一个或多个温度传感器不直接测量胰岛素或其它药物的温度，而是替代地位于电路板上并测量直接接触泵的胰岛素储存器的另一元件的温度，例如金属片。一个或多个温度传感器可以另外地或可替代地位于其他热敏部件或元件(例如，特定电路)上或其附近。该系统能够包括将感测到的温度转换成胰岛素或其它药物或感兴趣的部件或元件的预期温度的内部算法。因此，当本申请涉及确定或测量胰岛素或其它药物、部件或元件的温度的系统时，该系统实际上可以在泵中的不同位置处测量温度并且转换测量结果，而不是直接测量胰岛素或其它药物、部件或元件的温度。因此，阈值温度与能够对诸如胰岛素的药物有负面影响的温度直接相关，而不是与可能影响系统的电子器件或其它部件的温度相关。
当检测到温度处于或超过温度阈值时，系统能够实施用于防止和/或降低高温的多个程序中的一个或多个。可以有单个温度传感器测量泵中一个位置处的温度，或者可以有多个温度传感器测量多个位置处的温度。当采用多个温度传感器时，当温度测量的平均值超过阈值时或者当单个温度测量超过阈值时，可以触发警报。温度可以由一个或多个温度传感器获得和/或由处理器在连续的基础上或在周期性的基础上发送，例如，每秒一次、每分钟一次或两次等。尽管主要针对超过设定阈值的测量的温度值进行描述，但是在一些实施例中，能够关于温度的阈值变化率以类似的方式替代地或另外地采用一个或多个测量的温度值的变化率。
在一个实施例中，当测量的温度达到或超过预设温度阈值(或温度阈值的变化率)时，禁止感应充电。这能够通过泵向感应充电器发送信号以通过禁止从充电板传输电磁功率到泵从而暂停充电来完成。如果泵仍然连接到用户并且输送药物，则也能够暂停药物输送。当温度已经下降到可接受的充电水平时，感应充电能够被重新激活。在一些实施例中，能够以自动闭环方式来提供感应充电和药物输送的暂停和感应充电的重新激活。这种闭环系统还可以在泵和/或远程控制设备的用户界面上通知用户系统采取的动作中的一个或多个。例如，可以在用户界面上呈现警报，以通知用户感应充电和/或胰岛素输送已经被暂停，并且当感应充电和/或胰岛素输送已经被重新建立时，具有后续警报。这种警报还可以包括听觉和/或振动通知。在其他实施例中，系统可以响应于采取动作(例如恢复感应充电和/或药物输送)之前的一个或多个警报来要求用户确认。
在另一实施例中，当系统处于或高于阈值温度(或温度的变化率)时，系统能够替代地降低由充电板传输的电磁功率的量(即，充电速率)，而不是完全禁止感应充电。这能够通过将泵中的充电速率降低预定量来实现。一旦温度已经降低了期望的量，则能够增加充电速率。如果泵当前正在输送药物，则在一些实施例中，系统能够在充电速率降低时禁止药物输送，并且在恢复增加的充电时恢复输送。还可以进一步提供与系统采取的动作相关的一个或多个警报。在各种实施例中，系统能够自动地从事一个或多个动作，或者可以在从事一个或多个动作之前要求用户确认。在一些实施例中，如果温度继续升高或没有以期望的速率和/或量降低，则能够进一步降低或完全禁止充电速率。
尽管在降低充电的情况下温度将不会像完全禁止充电时那样快速降低，但是降低充电提供了优于暂停充电的优点，即设备仍将被连续充电。尽管降低充电速率已经被描述为完全暂停充电的替代方案，但是应当理解，这两种方法可以在单个充电过程中以交替或以其他周期性循环的方式一起采用。例如，在一个实施例中，如果温度超过第一阈值温度，则能够降低充电，并且如果温度超过第二、更高的阈值温度，则能够暂停充电。在其他实施例中，暂停充电和降低充电可以交替或周期性地循环，因为在一些情况下，连续降低充电可以更快地对电池充电，且在其他情况下，对于暂停充电期间，利用全功率充电可以更快地对电池充电。
通过使系统与本文描述的暂停或降低充电的通知和/或其他通知同时或独立，可以向用户提供一个或多个另外的通知。例如，无论是间歇地禁止充电还是降低充电速率，泵将花费比通常更长的时间来充电。因此，可以另外地通知用户电池可能花费比预期更长的时间来充电。此外，高温度和/或高温度变化率可能指示充电板中的传输线圈和泵中的接收线圈未恰当对准。因此，可以可替代地或另外地通知用户可能存在未恰当的对准和检查该对准。重复的温度警告可能指示充电板的问题，且因此在阈值数量的警告之后，能够通知用户充电板可能被损坏并更换充电板。另外，当温度已经超过阈值温度和/或达到甚至更高的阈值(例如，对于胰岛素为37摄氏度)时，能够通知用户胰岛素或其他药物可能已经降解和/或变质。本文描述的任何警告和警报能够进一步包括指示用户采取关于通知的动作。例如，在各种实施例中，能够结合对应的通知指示用户检查泵相对于充电板的对准，使用不同的充电板等。
详细通知(诸如以上描述的那些)能够在设备的用户接口上提供给用户，例如泵、专用远程控制器和/或具有用于控制泵的软件应用的远程消费电子设备，诸如智能电话。另外，泵或充电板中的一个或多个在其上能够包括指示灯。感应充电的问题能够可替代地或另外地由这样的指示灯、通过例如灯从关闭到打开、灯闪烁、灯以不同速率闪烁、灯改变颜色、灯亮度改变等来指示。在一些实施例中，不同的指示灯动作(例如，不同的闪烁速率)能够指示不同的充电问题或动作(例如，充电暂停或充电功率降低)。
尽管系统在本文中主要描述为基于温度测量来暂停和/或修改正在进行的感应充电，但是也可能存在泵开始时在已经升高的温度下放置在充电器上的情况。在这样的情况下，初始充电能够被降低、不被启动等，并且提供如本文所描述的关于暂停或修改正在进行的充电的警报。
现在参考图3，描绘了对诸如包含温度监测的非固定输注泵的医疗设备进行感应充电的方法200的流程图。在步骤202，将设备放置在充电器上，且在步骤203，充电板检测设备。在一些实施例中，如本文所述确定设备的温度，并在步骤204，在启动充电之前将该温度与一个或多个阈值温度进行比较。如果温度高于预定阈值，则在步骤206能够可替代地不启动充电或者在步骤208以降低的功率启动充电。在任一方法的情况下，在一些实施例中，能够在步骤210或步骤212通知用户采取的动作。可替代地，能够在没有用户通知的情况下采取相应的动作(如虚线箭头指示)。在各种实施例中，系统能够返回到步骤204并且继续连续地或周期性地监测温度。如果降低充电，在温度进一步升高时，或者如果温度没有以期望的速率和/或量降低，则可以进一步降低或禁止充电。这可以自动完成，或者，例如，可以在用户确认该警报之后完成。
如果确定温度低于预定阈值，则或者在开始时或者在清除警报之后，在步骤214，启动全功率充电以对设备充电。在一些实施例中，能够通知用户已经启动充电。在充电期间，在步骤216，能够在周期性地或连续地基础上监测温度并将该温度与预定阈值进行比较，该预定阈值可以与步骤204中的阈值相同或不同。如果温度低于预定阈值，则全功率充电继续，并且系统继续监测温度。如果温度高于预定阈值，则能够在步骤218可替代地暂停充电或在步骤220以降低的功率继续充电。能够分别在步骤222通知用户已经暂停充电或在步骤224通知用户已经降低充电，并且在一些实施例中，还能够在步骤224通知用户已经启动充电(以降低的功率)。可替代地，能够在没有用户通知的情况下采取相应的动作(如虚线箭头指示)。系统能够在步骤216自动地或响应于用户确认继续监测温度，并且当温度响应于暂停的或降低的功率充电而下降到预定温度以下时，重新启动全功率充电。如果开始时降低充电，并且温度继续增加或者没有以期望的速率和/或量降低，则可以进一步降低或禁止充电。上述步骤能够继续，直到设备电池被充满电或者直到设备以其他方式从充电器上移除。
在实施例中，上述的系统确定能够全部通过输注泵的处理器进行。例如，输注泵能够测量温度、比较温度，并且通过向板发送控制信号来使感应充电器禁止和/或调制所传输的功率，该控制信号使板的处理器根据控制信号来调整功率。在其他实施例中，这些确定中的一个或多个能够通过感应充电板的处理器或与泵通信的单独设备来进行，例如远程控制设备。
尽管系统和方法在本文中已经主要描述为应用于用于输送液体药物的输注泵，例如非固定胰岛素泵，但应当理解，本文的系统和方法能够与能够利用感应充电来对内部电池充电并且包括一个或多个热敏元件的任意设备一起采用。
