附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明一种实施方式中输液瓶的结构示意图。输液瓶1000A包括瓶体10A和与瓶体10A配合的瓶塞20A。
瓶塞20A包括与瓶体10A内的液体接触的瓶塞顶部21A，瓶塞20A内部还设置有重量传感器22A及通过导线24A与重量传感器22A连接的接口23A。 重量传感器22A设置在瓶塞顶部21A，可感测瓶体10A内的液体的重量。
接口23A设置于瓶塞20A的侧部，可与一功能组件(未示意)的接头连接，从而建立瓶塞20A与功能组件之间的通信连接，以使功能组件可获得液体重量信号，并根据液体重量信号进行相应地报警。在功能组件的接头插入接口23A后，瓶塞20A可从功能组件获得电能，从而重量传感器22A开始工作。
本实施方式中，由于瓶塞20A只内置重量传感器22A、接口23A及导线24A，而没有集成电源模块、控制器等器件，因此可降低瓶塞20A的制造成本，并减小由于器件过多造成防水可靠性和器件工作可靠性降低的现象。由于成本较低，因此瓶塞20A甚至可以作为一次性使用，而无需进行回收再利用。
本实施方式中，为了防止针头在插入瓶塞20A时损坏重量传感器22A，可在瓶塞20A的瓶塞底部25A设置保护元件26A。保护元件26A通常由金属等硬质材料制作，可防止尖锐物体的刺入。保护元件26A的设置位置应能使保护元件26A可保护重量传感器22A、接口23A及导线24A。在本实施方式中，重量传感器22A、接口23A及导线24A设置在瓶塞20A的同侧(左侧)，则在瓶塞底部25A与重量传感器22A和接口23A对应的位置(左侧)设置保护元件26A。
进一步，为了便于医护人员插入针头，还可在瓶塞底部25A的外表面上设置偏离保护元件26A的针头刺入指示符(未示意)。针头刺入指示符可为图案、文字、图案与文字的组合等。
图2为本发明另一实施方式中输液瓶的结构示意图。与输液瓶1000A的不同之处在于，本实施方式中输液瓶1000B的瓶塞20B包括可拆卸地连接于瓶塞顶部21B的重量测量模块221B。重量测量模块221B通过凸起等结构插入瓶塞顶部21B，以可与瓶体10B内的液体接触。进一步参考图3，重量测量模块221B包括重量传感器22B、无线通信模块23B和电源模块28。无线通信模块23B可为蓝牙通信模块、WIFI通信模块、非接触式IC卡式通信模块等。瓶塞20B通过无线通信模块23B与功能组件建立通信连接，以使功能组件可获得液体重量信号，并根据液体重量信号进行相应地报警。电源模块28为重 量测量模块221B提供电能。
本实施方式中，将重量传感器22B、无线通信模块23B及电源模块28集成在重量测量模块221B内，并且重量测量模块221B是可拆卸地连接于瓶塞20B，因此，在简化瓶塞20B的结构的情况下，还可重复利用重量测量模块221B，从而可降低使用成本。
图4为本发明又一实施方式中输液瓶的结构示意图。与输液瓶1000B的不同之处在于，本实施方式中输液瓶1000C的重量测量模块221C不包括电源模块，但包括LC振荡电路29(见图5)，以及瓶塞20C还包括设置于瓶塞20C侧部的接口231C。接口231C与功能组件的接头匹配，接收功能组件传输的耦合信号，LC振荡电路29与所述耦合信号产生谐振，为重量测量模块221C提供电能。如此，无需在重量测量模块221C内设置电源模块，可使重量测量模块221C的体积减小，防止电量不足而导致重量测量模块221C失灵的情况的发生，从而可提高可靠性。此外，LC震荡电路29也可集成于图1所示的瓶塞20A内，以对重量传感器22A供电。
与输液瓶1000B的相同之处，输液瓶1000C也包括无线通信模块232C(见图5)。瓶塞20C通过无线通信模块232C与功能组件建立通信连接，以使功能组件可获得液体重量信号，并根据液体重量信号进行相应地报警。
图6为本发明一种实施方式中输液瓶组件的结构示意图。本实施方式中的输液瓶组件100A包括瓶体101A、与瓶体101A配合的瓶塞201A及与瓶塞201A通信连接的功能组件。此处的输液瓶组件100指的是包括瓶体101A、瓶塞201A及功能组件三部分的输液瓶组件，当然，也可是仅包括瓶塞201A和功能组件的输液瓶组件。瓶塞201A与瓶塞20A相同，在此不再详细说明。
功能组件包括控制器31A和外露于功能组件的外壳37A并可与瓶塞201A的接口221A配合的接头32A。当接头32A插入瓶塞20A的接口221A时，功能组件与瓶塞201A可建立通信连接。
在功能组件与瓶塞201A建立通信连接后，控制器31A可从瓶塞201A获得重量传感器222A产生的液体重量信号，根据液体重量信号得出剩余液体重 量百分比，以及在剩余液体重量百分比满足预设条件时，控制功能组件301A发出警报。可通过光、声音、显示闪烁的画面等进行报警。
本实施方式中，在剩余液体不多时，即发出警报，可及时通知医护人员/患者，防止发生意外。
本实施方式中，剩余液体重量百分比满足预设条件可为剩余液体重量百分比等于或小于预设的重量百分比阈值，例如阈值可设为20％、15％，或其他合适的阈值。
本实施方式中，功能组件还包括触控屏33A和无线通信模块34A。触控屏33A可与瓶体101A连接，例如用吸盘的方式与瓶体101A连接。触控屏33A可为柔性触控显示屏，可贴附在瓶体101A上。医护人员可通过触控屏33A输入患者信息，例如患者姓名、医保号等。功能组件也可通过在触控屏33A上显示信息例如闪烁的画面进行报警。
功能组件通过无线通信模块34A与存储有患者输液数据的数据库连接。控制器31A根据输入的患者信息从数据库中确定患者需要输液的量，并设定相应的重量百分比阈值。如此，重量百分比阈值可根据患者的不同自动进行动态调整。
控制器31A还可将患者信息，例如患者的姓名，显示在触控屏33A上，方便医护人员快速找到患者。较佳地，为了节省能耗，可采用E-ink屏，断电时仍能持续显示信息。
本实施方式中，功能组件还包括电源模块35A。在功能组件与瓶塞201A建立通信连接后，电源模块35A为功能组件和瓶塞201A提供电能。
本实施方式中，由于功能组件与瓶塞201A的连接为可分离式连接，因而输液完成后，可拆卸功能组件，将其使用在其他的瓶塞上，从而降低使用成本。
图7为本发明另一种实施方式中输液瓶组件的结构示意图。与输液瓶组件100A不同之处在于，本实施方式中的输液瓶组件100B的功能组件还包括与控制器31B连接的液位传感器36。液位传感器36可为光电式液位传感器，可通过光线反射来测量液体的高度。使用时，将液位传感器36置于瓶底。控制 器31B可根据液体的高度信息得出剩余液体的重量百分比(下称第二剩余液体重量百分比)，并可在第二剩余液体重量百分比满足预设的条件(以下称为第二预设条件)时，控制功能组件发出警报。本实施方式中，第二剩余液体重量百分比满足第二预设条件可为第二剩余液体重量百分比等于或小于预设的重量百分比阈值(下称第二重量百分比阈值)。第二重量百分比阈值应当小于由液体重量传感器222B得出的剩余液体重量百分比(下称第一剩余液体重量百分比)的预设的重量百分比阈值(下称第一重量百分比阈值)。例如，第一重量百分比阈值设为20％时，第二重量百分比阈值设为15％。
本实施方式中，在重量传感器222B有效的情况下，因第一重量百分比阈值大于第二重量百分比阈值，第一重量百分比阈值先到达，因此功能组件在判断出第一剩余液体重量百分比等于或小于第一重量百分比阈值时，发出报警。随后，在第二剩余液体重量百分比等于或小于第二重量百分比阈值时，功能组件再次发出报警。当然，可选地，在其他实施方式中，若在第一剩余液体重量百分比等于或小于第一重量百分比阈值时，功能组件已发出了报警，则在第二剩余液体重量百分比等于或小于第二重量百分比阈值时，功能组件不再发出报警，以节省电能。
在重量传感器222B失效的情况下，即功能组件无法获得液体重量信号的情况下，则在第二剩余液体重量百分比等于或小于第二重量百分比阈值时，功能组件发出警报，即根据液位传感器36感测的高度信息进行报警。
本实施方式中，通过增加液位传感器36，可防止出现因重量传感器222B失灵而导致无法正常报警的情况，从而避免由于输液量超额甚至回血，造成医疗事故的情况。
进一步，由于液位传感器36的工作原理及位置均不同于重量传感器222B，因此同时发生故障的几率极低，可有效保障输液的正常进行。
以上所述是本发明的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
