Description

液体流量测量装置Liquid flow measuring device 技术领域Technical field
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。The invention relates to a device for applying biochemical reaction, chemical reaction, brewing, washing, feeding and measuring, and medical infusion, in particular to a shape like a dripper, which changes the continuous flow into a drip, detection liquid The device for the number of drops, the internal or external device cooperating with this, can calculate the flow rate and flow rate accordingly.
背景技术Background technique
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。For small flow measurement, it has always been an extremely difficult task, especially for flow measurement with flow rate of less than 1, 2 liters per hour or a few liters (such as 0.1-1.0 L/h). Conventional flow measurement methods such as turbines and vortex flowmeters have large starting flow rates, and it is impossible to measure small flows. Or it is difficult to achieve such a small flow rate range by using a float flowmeter that may be applicable. More precise processing.
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10,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。For the sake of explanation, we only use the existing medical infusion method to explain the existing technology. Other existing technologies for small-flow measurement such as feeding metering control are similar to the existing medical infusion methods, so we will not repeat them. . Referring to FIG. 10, the infusion bag 80 filled with the liquid medicine is suspended on the bracket, and the infusion tube 81 connected to the bottom of the infusion bag 80 is combined with the disposable needle 82 of the injectable body, and a drop is connected in the middle of the infusion tube 81. Bucket 83, the function of the drip bucket 83 is to provide the medical staff to observe the speed of the drip to prevent accidental occurrence. When used, the disposable needle 82 is inserted into the vein of the human body's arm, the back of the hand or the inner side of the thigh to achieve the effect of continuously injecting the liquid to the human body.
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。In the process of injecting the drug solution, the infusion rate is controlled by providing an infusion valve 84 around the infusion tube 81, and the infusion valve 84 is used to change the flowable area of the infusion tube 81 to control the speed and flow rate of the infusion. However, the regulating infusion valve 84 for controlling the infusion rate, in particular the electric or pneumatic regulating infusion valve 84, requires energy driving during use, and the power consumption is relatively large and the weight is relatively heavy, so the use is not so convenient.
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。The manner of adjusting the flow rate of the infusion tube 81 can adjust the speed of injecting the liquid into the human body. However, if the medical personnel need to know whether the speed of the liquid medicine is appropriate, or whether the liquid medicine in the infusion bag 80 is used up, it can only be artificial. The way of observing, recording, and calculating the recorded results can be known. This kind of manual observation and recording method can not automatically issue an alarm notification except when the infusion speed is abnormal. Other than the medical staff, it is also impossible to replace the new infusion bag 80 when the liquid medicine in the infusion bag 80 is used up in a timely manner. In addition, since the human operation factor has a high degree of uncertainty, such a manual observation and recording method is also likely to cause accidental occurrence such as medical negligence and blood counterflow such as inability to replace the infusion bag 80.
为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。In order to solve the above-mentioned uncertainty of human operation, there are technical solutions that the creators try to solve, using the counting method of weighing the infusion bag or installing the number of photoelectric detection spots next to the dripper to measure the infusion to some extent. Speed and infusion volume.
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。However, the disadvantage of the aforementioned weighing method is that the pipeline of the infusion tube is easily pulled, which affects the accuracy of the measurement. The method of installing photoelectric detection near the dripper, such as TW Patent Application No. 85213537, the patent case of the invention of the drip monitor, is to install a photodetector beside the dripper, and the disadvantage is that the dripper specifications produced by various manufacturers Different sizes and different sizes. This technology can only be applied to products that are produced by ourselves. If it is not for the different specifications of the dropper to produce different specifications, it is necessary to calibrate the size of the products for different manufacturers. The calculation of the flow rate, due to the large number of manufacturers of drip buckets, is a task that is very labor intensive, and the hospital is not convenient to cooperate. In addition, the technology of detecting the number of drops of photoelectricity is also easy to be affected by each The problem of light source interference.

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。When the invention is used, it can be used for metering in the fields of biochemistry, chemical engineering or mining. The following is a description of how the present invention can be used by way of example in which the present invention is used in series in a medical infusion system. When the invention is serially connected in the infusion system for metering, the upper end of the invention is inserted into the bottom of the infusion bag, and the top end of the infusion tube is connected to the bottom end of the liquid storage tube, and the infusion solution is arranged around the infusion tube. Adjusting the infusion valve of the flow rate, and connecting a dropper between the regulating infusion valve and the invention, and connecting a disposable needle to the outer end of the infusion tube, and flowing out of the infusion bag when the disposable needle penetrates into the human body The drug solution can be injected into the human body through the present invention, a drip bucket, an infusion tube, and a disposable needle.
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,使存液管内的药液逐渐淹过输液管的顶端以及引压通道的底端,最终药液的液面会位于存液管的中间并低于该压力连通管的顶端。When the infusion system of the present invention is used, the liquid medicine in the infusion bag first flows into the drip tube of the present invention, such as a dripper, and then the liquid medicine in the drip tube is intermittently dropped from the drip nozzle in a drip manner. Falling in the liquid storage tube, the liquid medicine in the liquid storage tube is gradually flooded through the top end of the infusion tube and the bottom end of the pressure guiding channel, and the liquid level of the final medical liquid solution is located in the middle of the liquid storage tube and lower than the top end of the pressure communication tube .
当药液从滴液管的滴嘴滴落存液管内时,会先滴落在压力连通管的顶端,由于液体不可压缩以及传递压力无方向性的特性,使得药液滴落压力连通管的压力能由压力连通孔内的药液传递至较接近引压通道底端的位置,接着随着存液管内的药液传递至引压通道内的空气,让压力感测模组量测到单位时间内点滴数量的压力变化,也感测到是否有药液的点滴滴落在存液管内,接着将前述压力感测模组量测到的压力讯息,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。 When the liquid medicine drops from the drip nozzle of the drip tube into the liquid storage tube, it will first drop on the top end of the pressure communication tube. Due to the incompressibility of the liquid and the non-directional property of the pressure transfer, the medicine droplet falls into the pressure communication tube. The pressure can be transmitted from the liquid in the pressure communication hole to a position closer to the bottom end of the pressure guiding channel, and then the pressure sensing module measures the unit time as the liquid in the liquid storage tube is transferred to the air in the pressure guiding channel. The pressure change of the number of droplets inside also senses whether there is a drop of the liquid medicine in the liquid storage tube, and then transmits the pressure information measured by the pressure sensing module to the data processing center wirelessly or by wire. Or a device or component such as a single chip performs calculation processing.
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压力感测模组量测到的压力讯息时,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。Since the size of the liquid droplets in the liquid drop tube by the drip nozzle is similar, and the size of each liquid medicine can be measured in advance by the same size drip tube, when the data processing center or the single wafer receives the pressure sensing When the pressure information measured by the module is measured, the flow rate of the liquid medicine and the speed of the liquid medicine flow per unit time can be calculated, so that the medical personnel can understand the condition of the infusion system and adjust the flow rate of the infusion system according to the demand of the infusion solution; or The data processing center or the single wafer can judge the amount of the liquid medicine in the infusion bag and whether it needs to be replaced after the message is not dropped, or judge that the pressure of the drip tube is lower than the pressure in the liquid storage tube. The problem of countercurrent flow of blood at the disposable needle.
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,以压力检测器配合滴管本体的设计,量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。Compared with the prior art, the present invention has the beneficial effects that the present invention is a device such as a drip bucket, which converts a continuous flow rate into a trickle flow, and performs a drop-by-drop counting, with a pressure detector matched with the design of the dropper body. Measuring the number of drops in the dropper body, providing a data processing center or a single chip and other microcomputers to automatically calculate the infusion rate of the infusion system, the amount of infusion, whether the infusion bag needs to be replaced, and whether blood reverse flow may occur, instead of manual recording The manpower and the errors that can occur when avoiding manual recording, and the ability to monitor the progress of the infusion process, automatically monitor the infusion process, and avoid medical negligence or human accidents.
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。The invention is a device which can operate independently. Since the device itself has a dropper body, the size of the measured drip is fixed, and it is not necessary to match the drip of the infusion system to calibrate the size of the drip, as long as the infusion is used. The capacity of the bag can correctly calculate the stock of the infusion bag, so it can be used on any existing infusion bag, without the cooperation of the infusion bag manufacturer. In addition, the invention has the advantages of small volume, low power consumption, and can be implemented by using a battery, and is very convenient to use. When the invention is connected to various feeding pipelines for feeding metering, the connection mode may be an insertion mode, a screw connection method or other quick joint connection manner.

The calculation process is performed accordingly, and then the result of the calculation process is compared with the value manually input by the operator to the data processing center 100, and then the wireless signal for controlling each driver 40 is sent to the wireless transmission unit 51 according to the result of the determination. The data transfer module 50 selectively controls the operation of each of the drivers 40. The process of the foregoing data processing center 100 in conjunction with the operation of the present invention is described in detail below.
请配合参看图5、图6,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,滴在压力连通管20顶端的斗部21上,使药液逐渐充满下存液管12、流量调整槽14、压力连通管20的压力连通孔22以及带孔板15内的连接孔154,在滴管本体10内的药液的液面高度最后会介于引压通道112的底端与压力连通管20的顶端之间。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。Referring to FIG. 5 and FIG. 6, when the tip end 181 of the drip tube 18 is inserted into the infusion bag 90, the liquid medicine first flows from the infusion bag 90 into the drip tube 18 of the drip tube body 10, and then the drip tube 18 The liquid medicine inside is intermittently dropped from the drip nozzle 182 in a drip manner, and is dropped on the bucket portion 21 at the top end of the pressure communication tube 20, so that the chemical liquid gradually fills the lower liquid storage tube 12, the flow regulating groove 14, and the pressure communication. The pressure communication hole 22 of the tube 20 and the connection hole 154 in the perforated plate 15 , the liquid level of the liquid medicine in the drop tube body 10 will finally be at the bottom end of the pressure guiding passage 112 and the top end of the pressure communication tube 20 . between. Then, the liquid medicine in the dropper body 10 is outwardly flowed out to the disposable needle 92 by the infusion tube 91 piercing the bottom of the dropper body 10, and then injected into the human body by the disposable needle 92.
在药液由滴嘴182间歇滴落的过程中,滴落在斗部21的药液会对压力连通孔22内的液体施加瞬间的压力,由于液体有不可压缩以及传递压力无方向性的特性,此瞬间的压力会透过连接孔154内的药液传递至引压通道112底端的周围,使该处的药液朝引压通道112内的空气施加压力,使压力感测模 组30能侦测到由滴嘴182间歇滴落的药液所产生的瞬间压力的大小、单位时间滴落药液的数量以及感知到有无持续滴落药液,并将上述的压力数据由数据传输模组50的无线传输单元51以无线的方式传输至数据处理中心100接收。During the intermittent dropping of the chemical liquid by the dropping nozzle 182, the chemical liquid dropped on the bucket portion 21 exerts an instantaneous pressure on the liquid in the pressure communication hole 22, and the liquid is incompressible and the pressure transmitting is non-directional. The pressure at this moment is transmitted to the periphery of the bottom end of the pressure guiding passage 112 through the liquid medicine in the connecting hole 154, so that the liquid medicine at the pressure is applied to the air in the pressure guiding passage 112, so that the pressure sensing mold is applied. The group 30 can detect the magnitude of the instantaneous pressure generated by the liquid medicine intermittently dripping from the drip nozzle 182, the amount of the liquid dropped per unit time, and the presence or absence of continuous dripping of the liquid medicine, and the above pressure data is The wireless transmission unit 51 of the data transmission module 50 is wirelessly transmitted to the data processing center 100 for reception.
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接收到压力感测模组30侦测到的压力数据时,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50的无线传输单元51发出控制各驱动器40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。Since the size of each drop of the liquid dripping from the outlet of the drip nozzle 182 is similar, and the size of each drop of the liquid can be measured in advance by the input data processing center 100, when the data processing center 100 receives the pressure sensing module 30. When the pressure data is obtained, the flow rate of the chemical liquid per unit time and the speed of the liquid medicine flow can be calculated, and the flow rate and speed of the liquid medicine are compared with the values input by the operator, for example, medical personnel, into the data processing center 100 in advance. Then, the data processing center 100 sends a wireless signal to the wireless transmission unit 51 of the data transmission module 50 to control the flow of the liquid medicine to adjust the flow rate of the liquid medicine to adjust the flow rate of the medical liquid to the value input by the medical staff in advance into the data processing center 100.
前述间歇滴落药液所产生瞬间压力的大小数据,能让数据处理中心100排除掉压力明显低于平均数值的数据,排除误报点滴数量的状况。前述有无持续滴落药液的数据处理,则是由于输液袋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,且此时压力感测模组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50的无线传输单元51发出控制各驱动器40禁止药液流出的无线讯号。The magnitude data of the instantaneous pressure generated by the intermittent drip solution allows the data processing center 100 to exclude data whose pressure is significantly lower than the average value, and eliminates the number of false alarms. The data processing of the presence or absence of the continuous dripping liquid is because the liquid medicine volume in the infusion bag 90 is known. If the data processing center 100 calculates that the volume of the liquid medicine flowing out of the infusion bag 90 conforms to the liquid medicine volume of the infusion bag 90, At this time, the data outputted by the pressure sensing module 30 indicates that there is no dripping liquid. At this time, the data processing center 100 can judge that the liquid medicine in the infusion bag 90 has been exhausted, and sends a message to notify the medical staff to replace the infusion bag 90, and at the same time The data processing center 100 sends a wireless signal to the wireless transmission unit 51 of the data transmission module 50 to control the flow of the drug solution from each of the drivers 40.
如图5、图7所示,若压力感测模组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50的无线传输单元51发出控制各驱动器40禁止药液流动的无线讯号。As shown in FIG. 5 and FIG. 7 , if the data output by the pressure sensing module 30 indicates that the drip nozzle 182 has no dripping liquid, and the data processing center 100 calculates that the volume of the liquid medicine flowing out of the infusion bag 90 is smaller than that of the infusion bag 90 . The liquid medicine capacity, at which time the data processing center 100 can judge that the pressure in the drip tube 18 is lower than or equal to the pressure outputted from the infusion tube 91, and the blood can be returned to the infusion tube 91 at the disposable needle 92. At this time, the data processing center 100 sends a wireless signal to the wireless transmission unit 51 of the data transmission module 50 to control the flow of the drug solution by each of the drivers 40.
请配合参看图8,当数据传输模组50的无线传输单元51收到数据处理中心100传输的控制各驱动器40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50选择性地驱动各驱动器40的感应线圈42,使各感应线圈42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。Referring to FIG. 8 , when the wireless transmission unit 51 of the data transmission module 50 receives the wireless signal transmitted by the data processing center 100 and controls each driver 40 to adjust the flow rate of the liquid medicine or stop the flow of the liquid medicine, the liquid medicine according to the required liquid medicine is required. The flow rate and the flow rate are high and low, and the induction coil 42 of each driver 40 is selectively driven by the data transmission module 50, so that the induction coils 42 drive the induction core rods 17 to move downward or return to the original position, so that the induction core rods 17 are The tapered portion 171 closes the corresponding flow adjustment hole 151, or makes the pair The flow rate adjustment hole 151 is in an open state. The above-described structure for adjusting the infusion flow rate of the present invention does not require an electric or pneumatic device having a driving action externally, so that the overall weight of the present invention can be as small as about 40 gram, compared to the existing infusion system requiring an external driving device. Only one-fifth of the weight makes the invention more convenient to use.
如图4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0以及1至7等8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。本发明通过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。As shown in FIG. 4, since the area of the three flow regulating holes 151 on the perforated plate 15 is a ratio of 1:2:4, the manner in which each of the induction core rods 17 is selectively closed to each of the flow regulating holes 151 can be combined. When there are 8 kinds of flow area changes such as 0 and 1 to 7, when three high flow rates and flow rates are required, all three flow adjustment holes 151 are opened, and when it is necessary to prohibit the flow of the liquid, it is three. The induction core rods 17 completely close the three flow adjustment holes 151. The method of the invention cooperates with the data processing center 100 to calculate the infusion flow rate and the flow rate, to detect whether the infusion bag 90 needs to be replaced, and to detect whether the disposable needle 92 has a blood countercurrent condition, and to monitor the whole process during the infusion.
