液体流量测量装置 技术领域
本发明涉及一种应用于生化反应、化工反应、酿造、洗矿中加料计量和控制，以及医疗输液的装置，尤其涉及一种形如滴斗的，将连续流量变为滴液，侦测液滴数量的装置，与此配合的内部或外部的装置可依此计算出流量速度、流量。
背景技术
对于小流量测量，一直是个极为困难的课题，特别是对于每小时流速仅仅1、2公升以下或者零点几公升(比如0.1-1.0L/h)的流量测量，更为困难。传统的流量测量方式如涡轮、涡街流量计，始动流量都较大，都无法实现小流量的测量；或者运用可能适用的浮子流量计，也难以达到如此小的流速范围，因此不得不对流量计进行更为精密的加工。
为便于说明，我们仅以现有医疗的输液方式加以说明现有的技术，其他用于加料计量控制等小流量量测的现有技术，与现有的医疗的输液方式相类似，故不赘述。请参看图9，是将内部装满药液的输液袋80悬挂在支架上，以输液袋80底部连接的输液管81结合可注射人体的一次性针头82，在输液管81的中间串接一滴斗83，该滴斗83的作用是提供医护人员观察滴液的速度，防止意外的发生。当使用时，是将一次性针头82插在人体的手臂、手背或是大腿内侧等处的静脉，达到对人体持续注射药液的效果。
前述注射药液的过程中，控制输液速度的方式是在输液管81的周围设有调节输液阀84，利用调节输液阀84改变输液管81可流通面积的大小来控制输液的速度与流量。但这种用于控制输液速度的调节输液阀84，特别是电动或者气动的调节输液阀84，在使用时需要能源驱动，功耗比较大、重量比较重，因此使用不是那么方便。
前述调整输液管81流量的方式虽可调整药液注入人体的速度，但医疗人员若要知道药液流动的速度是否适当，或输液袋80内的药液是否用尽时，都只能以人工的方式从旁观察、记录，并将记录的结果进行计算后才能得知，此种人工观察、记录的方式除了在输液速度异常时不能自动地发出警报通知 医护人员以外，也无法适时地在输液袋80内的药液用尽时更换新的输液袋80。此外，由于人为操作因素具有高度的不确定性，因此这种人工观察记录的方式也容易造成例如输液袋80更换不及等医疗上的疏失与血液逆流等意外的发生。
解决上述人为操作的不确定性，有创作人尝试提出解决的技术方案，利用对输液袋秤重，或在滴斗旁安装光电侦测点滴数量的计数手段，在一定程度上测量出输液的速度以及输液量。
然而前述的秤重方法的缺点是输液管的管线容易受到拉扯，影响测量的精度。在滴斗旁安装光电侦测的手段，如TW专利申请第85213537号，发明名称为点滴监视器的专利案，是在滴斗旁安装光电侦测器，其缺点是各厂家生产的滴斗规格、尺寸不同、点滴的大小各异，这种技术只能适用在自己生产的产品，要不是针对各厂家规格的滴斗生产不同规格的产品，就是要针对不同厂家的产品标定点滴的大小以进行流量的计算，由于生产滴斗的厂家众多，这是项工作量很大，且医院也不便进行配合的任务；除此以外，这种光电侦测滴液数目的技术，也还存在容易受各种光源干扰的问题。
发明内容
由于小流量测量的困难，本发明意在设计一种形如滴斗、将连续流变为点滴流，进行逐滴计数的装置，实现小流量的测量。它可以接入任何小流量管道上，也可以接入现有输液器管路中，进行液滴计数，以此计算输液的流速、流量以及判断输液是否停止或逆流的效果，发挥自动侦测药液流动状况的功效。
为达到上述目的，本发明提供一种液体流量测量装置，包括：
一滴管本体，设有一存液管，在该存液管的顶部穿设一滴液管，该滴液管的宽度窄于该存液管的宽度，在该滴液管的底部形成一滴嘴；以及
一拾音器，设于该滴液管的周围，该拾音器可侦测该滴液管内发出的声音。
进一步，本发明在所述存液管的周围形成一安装座，在该安装座设有一数据传输模组，该数据传输模组与该拾音器电连接，从而传输该拾音器侦测到的声音数据。
较佳的，本发明所述数据传输模组包括一无线传输单元，以该无线传输单元将所述拾音器侦测到的声音数据以无线的方式向外传输。
较佳的，本发明在所述数据传输模组上设有一单晶片，该单晶片与该数据传输模组电连接，接受该数据传输模组传输的声音数据，并依此感知所述滴液管是否有点滴落下、测量出落下的点滴数量、计算出单位时间通过所述滴液管的药液流量与流速。
进一步，本发明所述的存液管分为直线相连的一上存液管以及一下存液管，所述安装座分为上、下相结合的一上安装座以及一下安装座，且上、下安装座分别形成在上存液管底部的周围以及该下存液管顶部的周围，在上安装座与下安装座对接处的中间开设一流量调整槽，该流量调整槽的中间与上、下存液管相通，在该流量调整槽的中间嵌设一带孔板，该带孔板将该流量调整槽分隔为上、下两部分，在带孔板穿设两个或两个以上的流量调整孔，当设置三或四个流量调整孔时，其面积比为1：2：4或1：2：4：8﹔
在该安装座对正各流量调整孔的位置分别穿设一感应芯槽，各感应芯槽是竖直的孔洞并且内端与该流量调整槽相通，各感应芯槽的外端是封闭端，在该安装座对应各感应芯槽外端的位置分别设有一磁铁，在各感应芯槽的周围设置一电磁感应管以及一环绕该电磁感应管的感应线圈，利用电磁感应管可加强感应线圈产生的感应磁场的强度，各感应线圈与所述数据传输模组电连接，在各感应芯槽内设置一可受各磁铁吸引定位的感应芯棒，各感应芯棒的内端形成一尖锥部。前述本发明进一步设有的构造，当感应芯棒落下时，可将对应的流量调节孔堵上，使通过该流量调节孔的流量为零；当感应芯棒抬高时，对应的流量调节孔全通；这样当设置三个流量调整孔时，利用面积比为1：2：4的3个流量调节孔的开合情况组合，可以出现八种流量；如果当设置四个流量调整孔时，是利用1：2：4：8的4个流量调节孔的开合情况组合，则可以实现十六种流量。
进一步，本发明所述数据传输模组是以可拆卸的方式结合在所述上安装座上并位于所述上存液管旁，所述拾音器结合在所述数据传输模组靠近该上存液管的内侧；所述各感应芯槽是形成在所述上安装座，对应各感应芯槽的周围，在该上安装座的顶面朝下凹设一圆环形的线圈槽，各线圈槽与各感应芯槽同心，在各线圈槽内穿置一圆环形的线圈管，所述各感应线圈嵌设在各 线圈管内，所述各电磁感应管结合在各线圈管的内面，各线圈管的顶端连接在该数据传输模组的底部，所述磁铁结合在该数据传输模组的底部。
本发明使用时，可运用在生化领域、化工领域或采矿等领域中进行加料的计量。以下以本发明是串接在医疗的输液系统中使用为例子说明本发明如何使用。当本发明串接在输液系统中进行计量使用时，是将本发明的上端插入输液袋的底部，并将输液管的顶端连接在存液管的底端，该输液管的周围设有调节输液流量的调节输液阀，并在调节输液阀与本发明之间串接一滴斗，在该输液管的外端连接一一次性针头，当一次性针头刺入人体时，从输液袋内流出的药液可流过本发明、滴斗、输液管以及一次性针头而注入人体。
设有本发明的输液系统在使用时，输液袋内的药液会先流入本发明形如滴斗的滴液管，接着滴液管内的药液会从滴嘴以点滴的方式向下间歇滴落在存液管内，最终药液的液面会位于存液管的中间。
当药液从滴液管的滴嘴滴落到存液管内的药液时会发出声音，使得拾音器能从点滴滴落的声音侦测到单位时间内点滴的数量，也感测到是否有药液的点滴滴落在存液管内，接着将前述拾音器量测到的声音讯息，以无线或者有线的方式传输至数据处理中心或单晶片等装置或元件进行计算处理。
由于由滴嘴滴落存液管内的药液点滴的大小相近，且每滴药液的大小可预先由相同尺寸的滴液管处测得，因此当数据处理中心或单晶片接收到拾音器侦测到的声音讯息时，可据此计算出单位时间内的药液流量与药液流动的速度，让医疗人员理解输液系统的状况，依照输液的需求进行输液系统的流量调整；或者数据处理中心或单晶片可由没有药液滴落的讯息，判断出输液袋内的药液的用量以及是否用尽需要更换，或者判断出滴液管的压力低于存液管内的压力，可能会使一次性针头处产生血液逆流的问题。
与现有技术相比，本发明的有益效果在于：本发明是一种形如滴斗、将连续流量变为点滴流，进行逐滴计数的装置，以拾音器配合滴管本体的设计，侦测滴管本体内落下的点滴数量，提供数据处理中心或单晶片等微电脑自动计算出输液系统的输液速度、输液量、是否需要更换输液袋以及是否可能发生血液逆流的状况，可取代人工记录的人力以及避免人工记录时可能发生的误差，又能即时监控输液过程的进行，自动化监控输液的过程，避免医疗疏失或人为意外的发生。
本发明是一个可以独立运作的装置，由于装置自己具备滴管本体，因此受量测的点滴的大小为固定的大小，无需配合输液系统的滴斗另外标定点滴的大小，只要知道配合使用的输液袋的容量，即可正确计算出输液袋的存量，因此可使用在任何现有的输液袋上，不需要输液袋生产厂家的配合。此外，本发明的体积小，功耗亦小，使用电池就可以实施，运用上非常方便。当本发明接入各种加料管路进行加料计量时，其连接方式可以是插入方式、螺纹连接方式或者其他快速接头连接方式。

具体实施方式
为能详细了解本发明的技术特征及实用功效，并可依照说明书的内容来实施，进一步以如图式所示的较佳实施例，详细说明如下。
如图1～3所示的较佳实施例，本发明意在设计一种形如滴斗、将连续流量变为点滴流，进行逐滴计数的装置，其构造包括一形如滴斗的滴管本体10，以及分别设于该滴管本体10的三个驱动器20、一拾音器30、一数据传输模组40以及一外盖50，其中：
该滴管本体10设有一直管状的上存液管11以及一直管状的下存液管12，该上存液管11与该下存液管12是以上下直线相连的方式排列，在上存液管11周面的底部朝外凸设一上安装座111，在下存液管12周面的顶部朝外凸设一下安装座121，上安装座111与下安装座121分别是圆盘体且上、下结合，其结合手段可为黏合、扣合、锁合或铆合。
在上安装座111与下安装座121对接处的周围嵌设一密封环13，在上安装座111与下安装座121对接处的中间开设一流量调整槽14，该流量调整槽14是圆盘形的空间，并且该流量调整槽14中间的顶侧与中间的底侧分别与上存液管11、下存液管12内相通；
在该流量调整槽14的中间嵌设一带孔板15，该带孔板15是圆板体并且其中心与上存液管11以及下存液管12的中心同心，该带孔板15的周缘夹合 在上安装座111与下安装座121的对接处之间固定，该带孔板15将流量调整槽14分隔为上、下两部分，在带孔板15的周围以环绕且等间隔的排列方式垂直穿设三个流量调整孔151，三个流量调整孔151是圆孔并且面积的比例是1：2：4的比例。
在上安装座111位于各流量调整孔151上方的位置分别穿设一感应芯槽112，各感应芯槽112是竖直的孔洞并且内端与该流量调整槽14相通，各感应芯槽112的外端是封闭端，在上安装座111顶面对应各感应芯槽112外端的位置分别设有一磁铁16，在各感应芯槽112内设置一可受各磁铁16吸引定位的感应芯棒17，各感应芯棒17的内端形成一尖锥部171，对应各感应芯槽112的周围，在上安装座111的顶面朝下凹设一圆环形的线圈槽113，各线圈槽113与各感应芯槽112同心。
在上存液管11的顶部穿置一竖直的滴液管18，该滴液管18的宽度窄于上存液管11与下存液管12的宽度，在该滴液管18的顶部形成一尖端181，在该滴液管18的底部形成一漏斗状的滴嘴182，该滴嘴182伸入上存液管11内顶部的正中央，在下存液管12的底端嵌设一橡皮块19，该橡皮块19封闭下存液管12的底端。
各驱动器20分别在各线圈槽113内以可上下滑动的形态穿置一圆环形的线圈管21，在各线圈管21内嵌设一感应线圈22，在各线圈管21的内侧结合一电磁感应管23，使各驱动器20的感应线圈22以及电磁感应管23环绕在各感应芯槽112内的感应芯棒17的周围。
该拾音器30是高感度的麦克风并且设置在上存液管11的周围，该拾音器30较佳的设置方式是贴靠在该上存液管11的周面，使得该拾音器30能轻易地侦测到上存液管11内发出的声音。
该数据传输模组40的外形是圆环体，并且以可拆卸的方式结合在上安装座111上，该数据传输模组40环绕在上存液管11的周围，该数据传输模组40包括一无线传输单元41，该拾音器30结合在该数据传输模组40靠近上存液管11的内侧位置，且该拾音器30与该数据传输模组40电连接，使得数据传输模组40能以无线传输单元51将该拾音器30侦测到的声音数据以无线的方式向外传输，各磁铁16结合在该数据传输模组40的底部，各驱动器20的线圈管21的顶端连接在该数据传输模组40的底部，各感应线圈22与该数据 传输模组40电连接，使得各感应线圈22受该数据传输模组40驱动；当数据传输模组40向上拆离上安装座111时，该拾音器30、各磁铁16以及各驱动器20会一同离开原本定位在上安装座111的位置。
该外盖50是圆形的盖体并以可拆卸的方式套盖在上安装座111上，该外盖50的中间穿设一外盖穿孔51，以外盖穿孔51套设在滴液管18的周围，所述的数据传输模组40、拾音器30、以及各磁铁16容纳在外盖50内，受外盖50的保护。
前述的外盖50可以设计成具有隔音、遮光、防止电磁干扰等具有遮罩干扰功能的部件，比如用金属壳内衬吸音材料，做成各式感测器的罩壳而对于管线中之液体流量进行测量。当外盖50设为金属壳内衬吸音材料时，为避免无线传输单元41发出的无线讯号受到外盖50屏蔽，可在外盖50上设有一发送天线411，该发送天线411与无线传输单元41电连接，使原本可设置在外壳50内的天线移至外壳50的外面，确保无线传输单元41向外发送的无线讯号稳定。
相较其他同类竞争方案，例如将本发明感知液滴数位的拾音器感测器，代之以光电、智慧热敏感测器，虽其也一样可以感知落下的液滴，但是这样的技术方案的效果，因为其传感器必须直接测量滴斗内液体，不能如本发明使用金属壳内衬吸音材料的外盖50作为罩壳遮罩，以防止干扰，因此，其测量效果将远劣于本发明。而本发明乃将此类感测器皆直接安装在形似滴斗的滴液管18旁边，再加上外盖50的遮罩，可使其可靠性、抗干扰能力、测量效果等，因而大大的增强了。
本发明较佳实施例使用时，如图4至图6所示，是以运用在医疗的输液系统中为例子说明，当安装时是将本发明的滴液管18的尖端181刺入输液袋90的底部，该输液袋90的内部装有药液，再将输液管91的尖端911插入橡皮块19内，在输液管91的周围设有一调节输液阀93，在调节输液阀93与本发明之间串接一滴斗94，以该输液管91的外端连接一一次性针头92，以该一次性针头92可刺入人体进行药液的注射。
配合本发明的数据传输模组40以及各驱动器20，在本发明的外部设有一数据处理中心100，该数据处理中心100可接受本发明数据传输模组40的无线传输单元41所传输的无线讯号，据此进行计算处理，接着将计算处理的结 果，与操作者手动输入数据处理中心100的数值进行比对判断，接着依照判断的结果发出控制各驱动器20的无线讯号给无线传输单元41，令数据传输模组40选择性地控制各驱动器20运作。前述数据处理中心100配合本发明运作的过程详细说明如下。
请配合参看图4、图5，当滴液管18的尖端181刺入输液袋90内时，药液会从输液袋90先流入滴管本体10的滴液管18内，接着滴液管18内的药液会从滴嘴182以点滴的方式向下间歇滴落，滴入上存液管11与下存液管12，使药液逐渐充满下存液管12、流量调整槽14，在滴管本体10内的药液的液面高度最后会位于上存液管11内的中间。接着滴管本体10内的药液会由刺入滴管本体10底部的输液管91向外流出至一次性针头92处，再由一次性针头92向人体内注射。
在药液由滴嘴182间歇滴落的过程中，当药液的点滴滴落在下方药液的液面时会产生声音，使拾音器30能侦测到单位时间滴落药液的数量以及感知到有无持续滴落药液，并将上述的声音数据由数据传输模组40的无线传输单元41以无线的方式传输至数据处理中心100接收。
由于由滴嘴182出口滴落的每滴药液的大小相近，且每滴药液的大小可预先测得输入数据处理中心100，因此当数据处理中心100接收到拾音器30侦测的声音数据时，可据此计算出单位时间内的药液流量与药液流动的速度，并将此药液的流量、速度与操作者例如医护人员预先输入数据处理中心100的数值比较，接着数据处理中心100向数据传输模组40的无线传输单元41发出控制各驱动器20调整药液流量的无线讯号，使药液流量调整至医护人员预先输入数据处理中心100的数值。
前述有无持续滴落药液的数据处理，是由于输液袋90内的药液容量已知，若数据处理中心100计算出输液袋90流出的药液体积符合输液袋90的药液容量，且此时拾音器30输出的数据显示无滴落药液，这时数据处理中心100即可判断输液袋90内的药液已流尽，发出讯息通知医护人员更换输液袋90，同时数据处理中心100向数据传输模组40的无线传输单元41发出控制各驱动器20禁止药液流出的无线讯号。
如图4、图6所示，若拾音器30输出的数据显示滴嘴182无滴落药液，且数据处理中心100计算出输液袋90流出的药液体积少于输液袋90的药液 容量，这时数据处理中心100即可判断滴液管18内的压力低于，或者与输液管91输出的压力相等，一次性针头92处可能会发生血液逆流回输液管91的状况，这时数据处理中心100向数据传输模组40的无线传输单元41发出控制各驱动器20禁止药液流动的无线讯号。
请配合参看图7，当数据传输模组40的无线传输单元41收到数据处理中心100传输的控制各驱动器20调整药液流量或停止药液流出的无线讯号时，是依照所需要的药液流量、流速高低，以数据传输模组40选择性地驱动各驱动器20的感应线圈22，使各感应线圈22驱动各感应芯棒17向下移动或回复原位，使各感应芯棒17以其尖锥部171封闭对应的流量调整孔151，或使对应的流量调整孔151成为开放的状态。上述本发明用来调整输液流量的构造，无需在外部设有驱动作用的电动、气动装置，因此使得本发明整体的重量可以小至40公克左右，相较于需要外加驱动装置的现有输液系统，只有50分之一的重量，使本发明使用上更加方便。
如图3所示，由于带孔板15上的三个流量调整孔151的面积是1：2：4的比例，因此驱动各感应芯棒17选择性地封闭各流量调整孔151的方式可组合出零以及一至七等八种流通面积的变化，当需要较高的药液流量、流速时，是将三个流量调整孔151全部开啟，当需要禁止药液流动时，则是以三个感应芯棒17将三个流量调整孔151全部封闭。本发明藉由上述与数据处理中心100配合的方式，可达到计算输液流量、流速，侦测输液袋90是否需要更换以及侦测一次性针头92是否发生血液逆流状况的效果，发挥输液时全程监控的功效，避免人工记录输液速度所可能发生的疏失以及意外。
如图1、图2所示，由于本发明的外盖50为可拆，且该拾音器30结合在该数据传输模组40的内侧，各磁铁16结合在该数据传输模组40的底部，各驱动器20的线圈管21的顶端连接在该数据传输模组40的底部，因此当本发明使用完毕后，接触过药液的滴管本体10是医疗废弃物，是只能一次性使用的部分，使用完毕之后需要抛弃不可重复使用，但外盖50以及该数据传输模组40连同该拾音器30、各磁铁16以及各驱动器20可拆离滴管本体10的上安装座111重复使用，因此可重复配合一次性使用的滴管本体10组成本发明再次使用，达到节省费用的效果。
本发明除前述较佳实施例，是在外部设有所述的数据处理中心100，以外 部的数据处理中心100接受数据传输模组40传输的声音数据，以声音数据进行计算处理并且控制各驱动器20动作以外，请配合参看图8，也可以将数据处理中心100的功能以一单晶片101取代，将该单晶片101设于所述的数据传输模组40上，使该单晶片101与该数据传输模组40电连接，接受数据传输模组40直接传输拾音器30侦测到的声音数据，并控制各驱动器20驱动各感应芯棒17动作，此时数据传输模组40可不设有所述的无线传输单元41。当数据传输模组40拆离滴管本体10的上安装座111时，该单晶片101也可以随着数据传输模组40一同拆卸，同样具有可重复使用的效果。
本发明除前述较佳实施例，是将上存液管11与下存液管12分为两个部分以组成滴管本体10以外，也可以不设有所述的密封环13，直接将上存液管11及其周围的上安装座111，以及下存液管12及其周围的下安装座121结合为一体，成为存液管与设于该存液管周围的安装座的构造。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
