Description
本發明是關於黏度的檢測裝置及其運作方法,尤指一種液態流體黏度的檢測裝置及其運作方法。 The invention relates to a viscosity detection device and an operation method thereof, and more particularly to a liquid fluid viscosity detection device and an operation method thereof.
傳統測量剪切流變學中的流體黏度性質(Shear viscosity),主要可分作兩種類型,第一種為拖曳流式(Drag flows),是透過一移動物件與另一個固定物件來產生剪切應力,如旋轉黏度計(Parallel-plate viscometer);第二種為壓力流式(Pressure-driven flows),主要是透過壓力驅動流體通過封閉流道時產生剪切應力,如毛細管黏度計(Capillary viscometer)。 The traditional measurement of fluid viscosity properties (Shear viscosity) in shear rheology can be divided into two types. The first is drag flows, which generate shear through a moving object and another fixed object. Shear stress, such as a parallel-plate viscometer; the second is pressure-driven flows, which mainly generate shear stress when driving fluid through a closed flow channel through pressure, such as a capillary viscometer (Capillary viscometer).
在毛細管黏度計中,大多需要人工量測流動的時間來推算出流體黏度,且通常檢測樣本使用大量的液體用量(需數十至數百毫升),而在生醫檢測或重點照護檢測(Point-of-care testing)應用方面,病人樣本取得量通常只有1-5毫升。因此這類檢測方式雖然儀器較便宜,但測量準確度容易受到人為判斷與操作產生誤差,難以應用在量少或者貴重的液體上且檢測流程相當耗時。 Most capillary viscometers require manual measurement of the flow time to calculate the viscosity of the fluid, and usually a large amount of liquid is used in the test sample (requires tens to hundreds of milliliters), and in biomedical testing or focused care testing (Point -of-care testing) For application, patient samples are usually only 1-5 ml. Therefore, although this type of detection method is cheaper, the accuracy of measurement is easily subject to errors caused by human judgment and operation, it is difficult to apply to small or expensive liquids, and the detection process is quite time-consuming.
另一方面,旋轉式黏度計流體用量較毛細管式黏度計少(最少可用約1毫升)且測量的精準度較高,然而旋轉式黏度計的儀器大多較為 高價位,且旋轉黏度計在測量極低黏度的樣本時(例如:水溶液、極稀高分子溶液),會因為需要的較高的轉速而容易產生二次流(Secondary flow),進而導致檢測結果不準確。 On the other hand, rotary viscometers use less fluid than capillary viscometers (at least about 1 ml is available) and have higher accuracy. However, most of the instruments for rotary viscometers are more High price point, and when the rotating viscometer is used to measure very low viscosity samples (for example: aqueous solution, extremely dilute polymer solution), it will be easy to generate secondary flow due to the high speed required, which will lead to test results. Inaccurate.
有鑑於上述的問題,開發出一種流體用量少、檢測流程簡單快速且價格低廉的流體黏度檢測裝置,對於生醫檢測或者樣本稀有的黏度量測試實屬必要 In view of the above problems, the development of a fluid viscosity detection device with a small amount of fluid, a simple and fast detection process, and a low price is necessary for biomedical testing or the rare viscosity measurement of samples

本發明之一種流體黏度檢測方法,請參考圖2所示,其為本發明之流體黏度檢測方法流程圖。流體黏度檢測方法步驟包含:(S01)將一待測流體7放入前述之一流體黏度檢測裝置100的一注入槽2中;(S02)啟動一離心平台轉動該流體黏度檢測裝置100;(S03)該待測流體7被分布至該複數個流體黏度分析模組1中之該複數個黏度計位槽5中;(S04)以及讀取該待測流體7於該複數個黏度計位槽5上的一刻度6,即可輕易達成待測流體的黏度檢測。 For a fluid viscosity detection method of the present invention, please refer to FIG. 2, which is a flowchart of a fluid viscosity detection method of the present invention. The fluid viscosity detection method steps include: (S01) placing a fluid to be measured 7 into an injection tank 2 of one of the aforementioned fluid viscosity detection devices 100; (S02) activating a centrifugal platform to rotate the fluid viscosity detection device 100; (S03) ) The fluid to be measured 7 is distributed to the plurality of viscosity meter slots 5 in the plurality of fluid viscosity analysis modules 1; (S04) and the fluid to be measured 7 is read in the plurality of viscosity meter slots 5 A scale of 6 can easily reach the viscosity detection of the fluid to be measured.
在步驟(S01)中,該待測流體7為液態流體,且該流體黏度檢測裝置100的該注入槽2容積大小介於0.001到100毫升(ml)。 In step (S01), the fluid to be measured 7 is a liquid fluid, and the volume of the injection tank 2 of the fluid viscosity detection device 100 ranges from 0.001 to 100 milliliters (ml).
在步驟(S02)中,該流體黏度檢測裝置100設置於該離心平台上,當啟動離心平台的馬達時,離心平台帶動流體黏度檢測裝置100的碟體8旋轉,並透過旋轉時產生的離心力(Centrifugal Force),驅使注入槽2內的待測流體7往複數個流體黏度分析模組1個別包含的流道3分離,離心力的定義如下:F cen =ρω 2 r其中,ρ為待測流體密度(cm3/g),ω為馬達轉速(rpm),r為注入槽半徑(cm)。 In step (S02), the fluid viscosity detection device 100 is set on the centrifugal platform. When the motor of the centrifugal platform is started, the centrifugal platform drives the disc body 8 of the fluid viscosity detection device 100 to rotate, and transmits the centrifugal force generated during the rotation ( Centrifugal Force), which drives the fluid to be measured 7 in the injection tank 2 to reciprocate several fluid viscosity analysis modules 1 separately. The centrifugal force is defined as follows: F cen = ρω 2 r where ρ is the density of the fluid to be measured (cm 3 / g), ω is the motor rotation speed (rpm), and r is the radius of the injection tank (cm).
在步驟(S03)中,當待測流體7經由流道3流出並分布至該複數個流體黏度分析模組1中分析槽4所包含的複數個黏度計位槽5的過程中,待測流體7會受到流體黏度檢測裝置100轉動時所產生的科氏力(Coriolis Force),而產生與馬達轉動方向相反的流動,科氏力的定義如下: F cor =-2ρωv r 其中,ρ為待測流體密度(cm3/g),ω為馬達轉速(rpm),vr為待測流體流道速度(cm/s)。 In step (S03), when the fluid to be measured 7 flows out through the flow channel 3 and is distributed to the plurality of viscosity gauge slots 5 included in the analysis tank 4 in the plurality of fluid viscosity analysis modules 1, the fluid to be measured 7 is subject to the Coriolis Force generated when the fluid viscosity detection device 100 rotates, and generates a flow opposite to the direction of rotation of the motor. The Coriolis force is defined as follows: F cor = -2 ρωv r where ρ is to be Measure fluid density (cm 3 / g), ω is the motor speed (rpm), and v r is the flow channel speed (cm / s) of the fluid to be measured.
由科氏力公式可以得知,當待測流體7流速越快時,所受到的科氏力越強。當待測流體7流出流道3時,不同待測流體黏度會有不同的初速,待測流體7受到的科氏力大小也不同,因此不同黏度的待測流體7會流入不同的黏度計位槽5中,便可應用此原理快速地分辨出黏度計位槽5中不同黏度的待測流體7。更可以透過改變流道3流出口的截面積大小、碟體8的平均半徑位置或離心平台的馬達轉速來增加待測流體7的黏度檢測範圍。 It can be known from the Coriolis force formula that the faster the flow velocity of the fluid 7 to be measured is, the stronger the Coriolis force is. When the fluid to be measured 7 flows out of the flow channel 3, the viscosity of different fluids to be measured will have different initial velocities, and the Coriolis force on the fluid to be measured 7 will also be different. Therefore, the fluid to be measured 7 with different viscosities will flow into different viscosity gauges. In the tank 5, this principle can be used to quickly distinguish the fluids 7 to be measured with different viscosities in the viscometer slot 5. Furthermore, the viscosity detection range of the fluid to be measured 7 can be increased by changing the cross-sectional area of the outlet of the flow channel 3, the average radius position of the dish 8 or the motor speed of the centrifugal platform.
在步驟(S04)中,靜待一段時間,待所有待測流體7皆從注入槽2經由流道3流入分析槽4中的黏度計位槽5後,將馬達停止旋轉,即可讀取待測流體7於黏度計位槽5上的刻度6,輕易得知待測流體7的黏度。 In step (S04), wait for a period of time, after all the fluids 7 to be measured flow from the injection tank 2 into the viscometer gage 5 in the analysis tank 4 through the flow channel 3, stop the motor, and then read the data. The scale 6 of the measuring fluid 7 on the viscometer slot 5 can easily know the viscosity of the fluid 7 to be measured.
根據前述之流體黏度檢測裝置及其運作方法,請參考圖3所示,其為本發明流體黏度檢測裝置之不同待測流體黏度檢測示意圖。在本實施例中,第一待測流體71為黏度較低的液體,第二待測流體72為黏度較高的液體,當第一及第二待測流體71、72分別注入相同流體黏度檢測裝置100的注入槽2並啟動離心平台馬達轉;靜待一段時間後,離心力會驅動第一及第二待測流體71、72經由流道3流出且分布至流體黏度分析模組1中(本實施例為第一流體黏度分析模組11)分析槽4之黏度計位槽5中,透過黏度計位槽5上的刻度6可明顯得知,由於第一模組最大刻度a2大於第一模組最小刻度a1,即第二待測流體72的黏度高於第一待測流體71的黏度,藉此區分不同待測流體的流體黏度。 According to the foregoing fluid viscosity detection device and its operation method, please refer to FIG. 3, which is a schematic diagram of different fluid viscosity detection fluid to be measured in the fluid viscosity detection device of the present invention. In this embodiment, the first fluid to be measured 71 is a liquid with a lower viscosity, and the second fluid to be measured 72 is a liquid with a higher viscosity. When the first and second fluids 71 and 72 are injected with the same fluid viscosity, respectively, The injection tank 2 of the device 100 and the rotation of the centrifugal platform motor are started; after waiting for a period of time, the centrifugal force will drive the first and second fluids to be measured 71 and 72 to flow out through the flow channel 3 and be distributed to the fluid viscosity analysis module 1 (this The example is the first fluid viscosity analysis module 11) In the viscometer slot 5 of the analysis tank 4, it can be clearly seen from the scale 6 on the viscometer slot 5 that the maximum scale a2 of the first module is larger than the first mold Group minimum scale a1, that is, the viscosity of the second fluid to be measured 72 is higher than the viscosity of the first fluid to be measured 71, thereby distinguishing the fluid viscosities of different fluids to be measured.
亦根據前述之流體黏度檢測裝置100及其運作方法,請參考圖4所示,其為本發明流體黏度檢測裝置之一較佳實施例示意圖。在本實施例中,複數個流體黏度分析模組4以並聯方式個別與該注入槽2連接,首先將待測流體7(本實施例約為0.2毫升)注入流體黏度檢測裝置100碟體8中央的注入槽2中;接著啟動離心平台的馬達至特定轉速ω(本實施例約為3000rpm)轉動流體黏度檢測裝置100的碟體8,使得待測流體受到離心力的驅動分離至四個流道3截面積不同的黏度分析模組1中。 According to the aforementioned fluid viscosity detection device 100 and its operation method, please refer to FIG. 4, which is a schematic diagram of a preferred embodiment of the fluid viscosity detection device of the present invention. In this embodiment, a plurality of fluid viscosity analysis modules 4 are individually connected to the injection tank 2 in parallel. First, the fluid to be measured 7 (about 0.2 ml in this embodiment) is injected into the center of the disc body 8 of the fluid viscosity detection device 100 Into the injection tank 2; then start the motor of the centrifugal platform to a specific speed ω (about 3000 rpm in this embodiment) and rotate the plate 8 of the fluid viscosity detection device 100, so that the fluid to be measured is separated into four flow channels 3 by centrifugal force Viscosity analysis module 1 with different cross-sectional areas.
其中該第四流體黏度分析模組14之該流道(即第四流道34)截面積最大;該第三流體黏度分析模組13中該流道(即第三流道33)之截面積僅小於該第四流體黏度分析模組14中該流道(即第四流道34)之截面積;該第二流體黏度分析模組12中該流道(即第二流道32)之截面積僅小於該第三流體黏度分析模組13中該流道(即第三流道33)之截面積,且僅大於該第一流體黏度分析模組11中該流道(即第一流道31)之截面積;該第一流體黏度分析模組11中該流道(即第一流道31)之截面積最小。 The cross-sectional area of the flow channel (that is, the fourth flow channel 34) of the fourth fluid viscosity analysis module 14 is the largest; the cross-sectional area of the flow channel (that is, the third flow channel 33) in the third fluid viscosity analysis module 13 Only smaller than the cross-sectional area of the flow channel (ie, the fourth flow channel 34) in the fourth fluid viscosity analysis module 14; the cross-sectional area of the flow channel (ie, the second flow channel 32) in the second fluid viscosity analysis module 12 The area is only smaller than the cross-sectional area of the flow passage (ie, the third flow passage 33) in the third fluid viscosity analysis module 13, and is larger than the flow passage (ie, the first flow passage 31) in the first fluid viscosity analysis module 11. ); The cross-sectional area of the flow channel (ie, the first flow channel 31) in the first fluid viscosity analysis module 11 is the smallest.
由於四個黏度分析模組1的流道3截面積不同,待測流體7流出流道3的流速亦不相同(流道截面積越小,待測流體流速越快),使得待測流體7受到不同大小的科氏力而後流入四個黏度分析模組1的黏度計位槽5中;待所有待測流體7流入各分析槽4中的黏度計位槽5後(本實施例約為1分鐘),便將馬達停止旋轉,並依照待測流體7所在黏度計位槽5中的刻度6得知待測流體7的流體黏度。在本實施例中,第一模組最小刻度a1為1cP、第一模組最大刻度a2為15cP;第二模組最小刻度b1為20cP、第二模組最大刻度b2為130cP;第三模組最小刻度c1為200cP、第三模組最大刻度c2為 800cP;第四模組最小刻度d1為1000cP、第四模組最大刻度d2為2000cP,並由圖可知待測流體7的流體黏度約為50到60cP。 Due to the different cross-sectional areas of the flow channel 3 of the four viscosity analysis modules 1, the flow velocity of the fluid 7 to be measured out of the flow channel 3 is also different (the smaller the cross-sectional area of the flow channel, the faster the flow velocity of the fluid to be measured), making the fluid 7 to be measured Coriolis forces of different magnitudes then flow into the viscometer slot 5 of the four viscosity analysis modules 1; after all the fluid 7 to be measured flows into the viscometer slot 5 in each analysis tank 4 (about 1 in this embodiment) Minutes), stop the motor rotation, and obtain the fluid viscosity of the fluid 7 to be measured according to the scale 6 in the viscometer slot 5 where the fluid 7 to be measured is located. In this embodiment, the minimum scale of the first module a1 is 1cP, the maximum scale of the first module a2 is 15cP; the minimum scale of the second module b1 is 20cP, and the maximum scale of the second module b2 is 130cP; the third module The minimum scale c1 is 200cP, and the maximum scale c2 of the third module is 800cP; the minimum scale d1 of the fourth module is 1000cP, and the maximum scale d2 of the fourth module is 2000cP. According to the figure, the fluid viscosity of the fluid 7 to be measured is about 50 to 60cP.
請參考圖5所示,其為本發明流體黏度檢測裝置之另一較佳實施例示意圖。流體黏度檢測裝置100’包含:一碟體(圖未示);至少一注入槽2,設置於該碟體;一第一流體黏度分析模組11,包含:一第一流道31,與該至少一注入槽2連接;以及一第一分析槽41,與該第一流道31連接;以及一第二流體黏度分析模組12,包含:一第二流道32,與該第一流體黏度分析模組12(第一分析槽41)連接;以及一第二分析槽42,與該第二流道32連接。其中該第一分析槽41及該第二分析槽42皆包含複數個黏度計位槽5,且該複數個黏度計位槽5上設有複數個刻度6。 Please refer to FIG. 5, which is a schematic diagram of another preferred embodiment of the fluid viscosity detection device of the present invention. The fluid viscosity detection device 100 'includes: a dish (not shown); at least one injection tank 2 disposed in the dish; a first fluid viscosity analysis module 11 including: a first flow channel 31 and the at least An injection tank 2 is connected; and a first analysis tank 41 is connected to the first flow channel 31; and a second fluid viscosity analysis module 12 includes: a second flow channel 32 and the first fluid viscosity analysis module The group 12 (first analysis tank 41) is connected; and a second analysis tank 42 is connected to the second flow channel 32. The first analysis slot 41 and the second analysis slot 42 each include a plurality of viscometer position slots 5, and the plurality of viscometer position slots 5 are provided with a plurality of scales 6.
在本實施例中,流體黏度分析模組1的數目為兩個,以串聯方式與該注入槽2連接,其串聯方式為第一流體黏度分析模組11的第一分析槽41透過第一流道31與注入槽2連接,第二流體黏度分析模組12的第二分析槽42透過第二流道32與第一流體黏度分析模組11(第一分析槽41)連接。在其他可能的實施例中,複數個流體黏度分析模組1的數目可以大於或小於兩個,其數目可依照技術人員自由調整,本發明不應以此為限。 In this embodiment, the number of the fluid viscosity analysis modules 1 is two, which are connected to the injection tank 2 in a serial manner, and the serial manner is that the first analysis tank 41 of the first fluid viscosity analysis module 11 passes through the first flow channel. 31 is connected to the injection tank 2, and the second analysis tank 42 of the second fluid viscosity analysis module 12 is connected to the first fluid viscosity analysis module 11 (the first analysis tank 41) through the second flow channel 32. In other possible embodiments, the number of the plurality of fluid viscosity analysis modules 1 may be greater than or less than two, and the number may be adjusted freely by a technician, and the present invention should not be limited to this.
在本實施例中,該第二流體黏度分析模組12之該流道(即第二流道32)截面積最大,該第一流體黏度分析模組11中該流道(即第一流道31)之截面積最小,由於黏度分析模組1的流道3截面積不同,待測流體7流出流道3的流速亦不相同(流道截面積越小,待測流體流速越快),藉此增加待測流體7的量測範圍。在其他可能的實施例中,若流體黏度分析模組1串聯的數目增加,而增加流體黏度分析模組1的流道3則大於第二流道32,依 此類推,本發明不應以此為限。 In this embodiment, the cross-sectional area of the flow passage (ie, the second flow passage 32) of the second fluid viscosity analysis module 12 is the largest, and the flow passage (ie, the first flow passage 31) in the first fluid viscosity analysis module 11 ) Has the smallest cross-sectional area. Because the cross-sectional area of the flow channel 3 of the viscosity analysis module 1 is different, the flow velocity of the fluid 7 to be measured out of the flow channel 3 is also different (the smaller the cross-sectional area of the flow channel, the faster the flow velocity of the fluid to be measured). This increases the measurement range of the fluid 7 to be measured. In other possible embodiments, if the number of fluid viscosity analysis modules 1 is increased in series, and the flow channel 3 of the fluid viscosity analysis module 1 is increased to be greater than the second flow channel 32, depending on By analogy, the present invention should not be limited to this.
在本實施例中,流體黏度檢測方法步驟如下:首先將待測流體7注入流體黏度檢測裝置100’中央的注入槽2中;接著啟動離心平台的馬達至特定轉速ω轉動流體黏度檢測裝置100’的碟體,使得待測流體7受到離心力的驅動流至第一流道31,並順沿著第一流道31流入第一分析槽41中。此時,當待測流體7的黏度較小,待測流體7受到科氏力的驅動後流入第一分析槽41的黏度計位槽5中,停止馬達旋轉,讀取刻度6進而得知待測流體7的流體黏度;若待測流體7的黏度較大,則待測流體7可能流至與第一流體黏度分析模組11(第一分析槽41)連接的第二流道32,順沿著第二流道32流入第二分析槽42中,並受到科氏力的驅動後流入第二分析槽42的黏度計位槽5中,停止馬達旋轉,讀取刻度6進而得知待測流體7的流體黏度。其中該待測流體7在第一分析槽41或第二分析槽42流動時,該待測流體7須與第一分析槽41或第二分析槽42其中之一分析槽接觸,或同時與第一分析槽41和第二分析槽42同時接觸。 In this embodiment, the steps of the fluid viscosity detection method are as follows: first, the fluid 7 to be measured is injected into the central injection tank 2 of the fluid viscosity detection device 100 '; then the motor of the centrifugal platform is started to rotate the fluid viscosity detection device 100' to a specific rotation speed ω The plate body makes the fluid 7 to be measured flow to the first flow path 31 by centrifugal force, and flows into the first analysis tank 41 along the first flow path 31. At this time, when the viscosity of the fluid to be measured 7 is small, the fluid to be measured 7 is driven by the Coriolis force and flows into the viscometer groove 5 of the first analysis tank 41. The rotation of the motor is stopped, and the scale 6 is read to know Measure the viscosity of the fluid 7; if the viscosity of the fluid 7 to be measured is large, the fluid 7 to be measured may flow to the second flow channel 32 connected to the first fluid viscosity analysis module 11 (the first analysis tank 41), It flows into the second analysis tank 42 along the second flow channel 32, and is driven by the Coriolis force and flows into the viscometer slot 5 of the second analysis tank 42. Stop the motor rotation, read the scale 6 to know the test Fluid viscosity of fluid 7. When the fluid to be measured 7 flows in the first analysis tank 41 or the second analysis tank 42, the fluid 7 to be measured must be in contact with one of the first analysis tank 41 or the second analysis tank 42 or simultaneously with the first analysis tank 41 One analysis tank 41 and the second analysis tank 42 are in contact simultaneously.
