Description

一种智能输液泵
技术领域
本发明涉及医疗输液设备，尤其涉及一种用于医院对病痛患者进行恒速静脉输注药液时，能够准确连续输注的输液装置。
背景技术
对于病痛患者，医生经常采用输液方式来治疗。现有的输液泵都是采用国外上个世纪的技术产品， 基本上是照搬过来仿制而成，没有什么创新而言。其设备主要分为单片机控制部分、面板按键部分、液晶屏显示部分及蠕动挤压部分。其动力部分就是蠕动挤压部分，即通过机械蠕动的方式连续挤压输液管将药液输出。然而，输液管必须采用价格昂贵的 PVC 专用管，否则无法使用。因为一般的一次性输液管被连续挤压后容易产生变形或破裂，不但影响输液精度，还给输液工作带来安全隐患。另外，此设备操作环节繁琐，也不能随意移动，使用起来不够方便。
如何设计出方便、安全高效又物美价廉的医疗输液设备，是业界亟待解决的技术问题。
发明内容
本发明为了解决上述技术问题，提出一种方便、安全高效的又物美价廉的医用智能输液泵。
本发明提出的智能输液泵，其包括外壳、设于外壳内下部的控制电路板、设于外壳一侧的输入及显示装置、设于外壳正面上部的输液瓶支撑座。所述外壳的背面设有一空气净化器，该空气净化器的进气口朝外，而出气口朝内并与一电机气泵组件的气泵进气口联通，电机气泵组件的气泵出气口通过带有一空气止回阀的输气管与设于所述外壳正面的一密封接头连接，在空气止回阀与壳体的密封接头之间的输气管中联通一气压传感器；所述外壳内部还设有一输液的流量控制机构和电源装置，外壳正面所述支撑座的下部设有一红外线检测头；所述的控制电路板与所述的输入及显示装置、电机气泵组件、气压传感器、流量控制机构、红外线检测头及电源装置保持电联接。
较优的，所述外壳正面上部的输液瓶支撑座背面的壳体为一透明窗，外壳内设有一与所述控制电路板电连接的扫描器，该扫描器的扫描头对准所述的支撑座壳体上的透明窗。
较优的，所述的空气净化器包括：空气净化***和紫外杀菌***；所述的空气净化***包括：防护罩和依次安装在防护罩内的纤维过滤层、颗粒吸附层和高效过滤层；所述的紫外杀菌***包括：与所述防护罩连接的紫外线杀菌仓、安装在紫外线杀菌仓内的紫外光源和锥形紫外聚光罩，紫外聚光罩通过一接口，或直接与所述电机气泵组件的气泵进气口的输气管连接。
较优的，所述的流量控制机构包括：与所述控制电路板电连接的微动电机、与微动电机连接的往复移动机构和限位开关、设于往复移动机构移动前向的挡板。
较优的，所述外壳的一侧设有与所述控制电路板电连接的扬声器。所述的电源装置为充电电池。
较优的，所述外壳上部设有一转动把手，与所述显示屏相对的一侧的外壳上设有一钩挂孔。所述外壳背面设有操作面板和一内抠把手（ 16 ）。
较优的，所述的红外线检测头与输液观察瓶的支架设置成一体。所述的密封接头内还设有一紫外线二极管。
本发明利用气泵向输液瓶内加压来弥补输液瓶因降低了高度而缺失的重力压差，这个压差是通过单片机精确计算并可根据压力变化自行调节压差，使输液过程平稳流畅。由于利用气泵提供压力，取消了常用的利用机械蠕动来挤压输液管的方式，所以使用普通的输液管就可满足需要，从而降低了使用成本，还提高了安全性能。另外，本发明在气泵进气口连接一空气净化装置，当气泵抽吸大气中的空气时，可以先通过该空气净化装置对空气中的有害细菌及其他粉尘烟灰进行灭菌杀毒和过滤，进入输液瓶内洁净气体不会对药液造成污染，而危害病人的安全。空气净化装置在输液乃至医疗领域内的应用将彻底杜绝和防止因空气污染而造成的危害。除掉通过输入及显示装置输液时相关信息外，还可以通过设置的扬声器进行语音信息的播报，大大方便了医务工作者、患者或患者家属及时进行处理。本发明为台式设计，能够自由摆放和移动中输液，使用便捷、安全，还价格便宜，将会得到广大医务工作者和患者的欢迎。

图 1 ～ 3 示出了本发明的一种实施例的基本结构，所述的智能输液泵包括：由左侧壳体 20 、右侧壳体 50 和正面壳体 60 、后侧壳体 30 构成的外壳、设于外壳正面上部的由左右支撑壳体 40 构成的输液瓶 3 支撑座，而支撑座背面的壳体为一透明窗 12 ，还有设于左侧外壳 20 上的输入及显示装置 2 、设于左侧外壳的扬声器 13 、设于右侧外壳 50 上的钩挂孔 15 、铰接于外壳上部的一可转动把手 14 。外壳正面所述支撑座的下部设有一红外线检测头 10 ，该红外线检测头 10 与输液观察瓶 22 的支架设置成一体。红外线检测头 10 支架一侧的外壳上还设有固定输液管 21 的防折弯引导槽 25 及防折弯导柱 18 。外壳正面铰接一可将外部光源中的紫外线过滤掉的紫外线滤光罩 17 ，打开该滤光罩可以放置输液瓶 3 及固定输液管或更换输液瓶。合上该滤光罩可以开始输液。外壳的背面设有一空气净化器 4 ，该空气净化器的进气口朝外，而出气口朝内并与一电机气泵组件 5 的气泵进气口联通，请参阅图 5 ，电机气泵组件 5 的气泵出气口处通有一空气止回阀 7 ，在空气止回阀 7 与设于外壳正面的一密封接头 8 连接的输气管 23 中还联通一气压传感器 6 。该密封接头 8 内还设有一紫外线二极管（图中未示出）。外壳内设有一扫描器 11 ，该扫描器的扫描头对准支撑座背面壳体上的透明窗 12 。外壳内部的下方还设有一控制电路板 1 、输液的流量控制机构 9 和电源装置，本实施例中，电源装置采用充电电池 27 。控制电路板 1 可以采用单片机，其与输入及显示装置 2 、气压传感器 6 、扬声器 13 、电机气泵组件 5 、流量控制机构 9 、红外线检测头 10 、扫描器 11 及电源装置保持电联接并可以根据设置协调控制各部件或元器件的工作。空气净化器 4 由空气净化***和紫外杀菌***组成（图中未示出）。空气净化***可以包括：防护罩和依次安装在防护罩内的纤维过滤层、颗粒吸附层和高效过滤层；紫外杀菌***可以包括：与防护罩连接的紫外线杀菌仓、安装在紫外线杀菌仓内的紫外光源和锥形紫外聚光罩，紫外聚光罩通过一接口，或直接与电机气泵组件 5 的气泵进气口的输气管 23 连接。如图 5 、图 6 所示，流量控制机构 9 包括：与所述控制电路板 1 电连接的微动电机 91 、与微动电机连接的往复移动机构 92 和限位开关 94 、设于往复移动机构 92 移动前放的挡板 93 ，而一输液管 24 设于复移动机构 92 和挡板 93 之间。如图 4 所示，后侧壳体 30 上还设有一内抠把手 16 和操作面板 19 。操作面板上根据需要可以设置：电源启动键、扬声器静音键、条码转换开关、信息查询键、消毒开关、电源插座和信号搜索键等等器件。输入及显示装置 2 可以显示多种触摸功能按键，如，运行-在各项设置完成后，可执行现有设置、暂停-按下后可停止输液、锁定-对各项设置进行安全保护。还可以显示设置的项目：输液的滴速（滴 / 分），' + - '键-用于选择滴速的增加或减少，定量 - 是特选键，用于选择 50 毫升、 100 毫升、 150 毫升 200 毫升四种特定输液量的输液，电源-启动仪器后，电量信息显示、此时电源指示灯亮、输液过程中运行灯闪烁、关机-按压 3-5 秒钟，流量控制机构打开并关机。根据需要还可通过单片机 1 来调整显示屏的显示项目。
如图 3 、图 5 所示，本发明是这样工作的，接通电源、将插接有一次性输液管的输液瓶 3 倒置放入输液瓶支撑座上，将输液管 21 围绕防折弯导柱 18 转一圈卡入防折弯引导槽 25 ，以免输液管折弯截断液流或以免移动时输液瓶 3 脱出。输液观察瓶 22 卡在带有红外线检测头 10 的支架上，将输液观察瓶 22 出液口的另一输液管 24 卡入流量控制机构 9 的挡板 93 与往复移动机构 92 之间（参阅图 6 ）。再将与输液瓶 3 连接的一输气管 26 的接头与密封接头 8 连接。然后通过液晶显示屏 2 进行设置：滴速、定量等参数（不设置则执行默认置，即滴速 30/ 分钟、无定量控制）。按'运行'键启动电机气泵组件 5 泵气对输液管整体进行排空，按压'暂停'键排空中止，便可对人体进行输注液的扎针等动作，再次按压'运行'键输液开始。电机气泵组件 5 工作中通过空气净化器 4 吸入空气，经过过滤、灭菌的空气由输气管 23 输入气泵，经气泵加压后再由另一输气管 23 通入密封接头 8 ，并由输气管 26 将压力气体送入输液瓶 3 。而流经密封接头 8 的压力气体还可以由设于密封接头内部的紫外线二极管发出的紫外线再次灭菌，从而确保空气的洁净。在压力气体的作用下，输液瓶中的药液由输液管 21 进入输液观察瓶 22 ，再经过输液管 24 对患者进行输液。红外线检测头 10 负责对输液观察瓶 22 内的液滴进行检测，并将检测的信号传送到单片机 1 中，单片机根据检测信号作出处理，即给流量控制机构 9 的微动电机 91 发出指令，驱动往复移动机构 92 向与挡板 93 之间的输液管 24 进行挤压或放松，固定在流量控制机构 9 上面的限位开关 94 能够准确控制往复移动机构 92 的移动距离，从而自如地调节输液的流量。气压传感器 6 负责对输气管内气压的检测，并将检测的信号传送到单片机 1 中，单片机根据检测信号作出处理，即给电机气泵组件 5 发出指令，使得气泵加压或保持压力不变。空气止回阀 7 用于防止压力空气回流。
单片机 1 是整个***的'大脑'，对整个***进行智能控制和管理，并对检测信号进行处理。设备出现故障时，可以及时报警并停止电机气泵组件 5 工作，流量控制机构 9 压紧输液管 24 阻止输液进行，从而保证患者的安全。若本发明用于较大的医疗机构时，由于患者众多，还可以设置启动扫描器 11 开始工作。该扫描器通过输液瓶支撑座上的透明窗 12 ，对输液瓶 3 上的条码进行扫描，并将扫描的信息输入单片机 1 进行比对，若发现输液瓶 3 内的药品与被输液的患者不对应，则会即刻停止输液操作，以确保安全。本发明还可以设置报警装置：通过传感器感应到的信号经单片机处理后，得出报警控制信号，再由报警装置响应，引起人们的注意，同时进行正确的处理。主要有光电报警（发光二极管）和声音报警（扬声器和蜂鸣器）等。
输入及显示装置：输入部分负责设定输液的各参数，如输液量和输液速度等。显示部分负责显示各参数和当前的工作状态等，可采用段式液晶显示或 LCD 彩色液晶显示。机体后外壳上设有 9V 直流电源插座，可给设备输入工作电流或给充电电池充电：充电电池为输液泵在无交流电的情况下提供电能，使输液泵继续工作。
由于利用气泵提供压力，取消了常用的利用机械蠕动来挤压输液管的方式，所以使用普通的输液管就可满足需要，从而降低了使用成本，还提高了安全性能。另外，本发明在气泵进气口连接一空气净化装置，使得进入输液瓶内洁净气体不会对药液造成污染，而危害病人的安全。本发明能够自由摆放和移动中输液，使用便捷、安全，还价格便宜，将会得到广大医务工作者和患者的欢迎。
以上具体实施例仅用以举例说明本发明的结构，本领域的普通技术人员在本发明的构思下可以做出多种变形和变化，这些变形和变化均包括在本发明的保护范围之内。
