[Technical field]

[0001] The present invention relates to a component for an analyzer used in an analyzer for analyzing the characteristics of a liquid flowing through a flow path of a tubular member. [Background technology]

[0002] There have been known components for an analyzer used in an analyzer that analyzes the characteristics of a liquid flowing through a flow path. For example, the following Patent Document 1 discloses a flow tube housing member that includes a concave liquid reservoir having a first recess on the input opening side and a second recess on the bottom side, and in which a supply port of a glass tube that constitutes a flow path is disposed at the bottom of the liquid reservoir. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-122370 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the flow tube housing member described in the above Patent Document 1, the liquid reservoir has a multi-stage structure having a first recess and a second recess, and therefore tends to be bulky.

[0005] The present invention has been made in consideration of the above circumstances, and has an object to provide an analytical device component that can be made thinner. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, configuration 1 of the analytical device component of the present invention is a component for an analytical device used in an analytical device that analyzes the characteristics of a liquid passing through a flow path of a tubular member, and is characterized in that it comprises a liquid-resistant sheet body that is formed to surround the receiving port of the tubular member arranged on the upper side in a planar view and constitutes a dripping portion having a substantially flat surface onto which liquid is dripped, a flow stopper portion that is arranged to surround the periphery of the dripping portion, and a movement suppression portion that suppresses the movement of the tubular member.

[0007] The following description of the embodiments discloses that the analytical device component according to the present invention may include the following subsidiary configurations. <Configuration 2> In configuration 1, the flow stopping portion may be a flow stopping wall surface formed on the sheet body so as to rise from a periphery of the dripping portion. <Configuration 3> In configuration 2, the flow blocking wall surface may be formed by deforming the sheet body in a thickness direction. <Configuration 4> In configuration 2, the sheet body may include a first sheet body constituting the dripping portion, and a second sheet body constituting the flow stopping wall surface and laminated on the first sheet body. <Component 5> In any one of configurations 1 to 4, the movement suppressing portion may be a movement suppressing wall surface formed on the sheet body so as to rise on both sides in a width direction, which is a direction perpendicular to the length direction of the tubular member and the direction along the thickness direction of the sheet body. <Component 6> In configuration 5, the movement suppression wall surface may be formed by deforming the sheet body in a thickness direction. <Component 7> In configuration 5, the sheet body may include a first sheet body constituting the dripping portion, and a second sheet body constituting the movement suppression wall surface and laminated on the first sheet body. <Component 8> In any one of configurations 1 to 4, the movement suppressing portion may be an adhesive material laminated on the sheet body. <Component 9> In any one of configurations 1 to 8, the sheet body may have a dimension along the length direction of the tubular member that is greater than the length dimension of the tubular member. <Component 10> In any one of configurations 1 to 9, the device may further include a base member having a recessed accommodation portion formed therein and adapted to accommodate the sheet body at its bottom. <Component 11> In configuration 10, the movement suppressing portion may be provided on the base member. Effect of the Invention

[0008] Since the analytical device member of the present invention has the above-mentioned configuration, it can be made thin. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a block diagram illustrating an analysis device in which the analysis device member is used.

[0010] Hereinafter, an example of an analytical device member according to the present embodiment will be described with reference to the drawings. Note that in some drawings, some of the detailed reference numerals used in other drawings are omitted. 1 and 2 are diagrams showing an example of an analytical device member according to the first embodiment and an example of an analytical device in which the analytical device member is used.

[0011] 1 and 2, an analytical device member 7 of this embodiment is used in an analytical device 1 that analyzes the characteristics of a liquid passing through a flow path 2a of a tubular member 2. The analytical device member 7 is formed so as to surround the receiving port 2b of the tubular member 2 arranged on the upper side in a plan view, and includes a liquid-resistant sheet body 8 that constitutes a dripping portion 9 having a substantially flat surface onto which liquid is dripped, a flow stopper 10 provided so as to surround the periphery of the dripping portion 9, and a movement suppressing portion 12 that suppresses the movement of the tubular member 2. With this configuration, the dripping portion 9 is configured to have a substantially flat surface, so that it can be made thinner than a configuration with a liquid reservoir having a multi-stage structure. Furthermore, if the dripping portion 9 is a disposable member that is thrown away, the amount of waste can be reduced. Furthermore, since the receiving port 2b of the tubular member 2 is only required to be disposed above the dripping portion 9, the positioning of the tubular member 2 is easier than a configuration in which the supply port of the glass tube must be positioned at an appropriate position in the liquid reservoir. Since the sheet body 8 is liquid-resistant, the liquid can be permeated and the liquid can be prevented from leaking downward from the sheet body 8. Furthermore, since the flow stopper 10 is provided so as to surround the dripping portion 9, the flow stopper 10 can prevent the liquid from leaking to the outside. Furthermore, the movement suppression portion 12 can suppress the movement of the tubular member 2. The details are explained below.

[0012] As shown in Fig. 2, the analysis device 1 is configured to analyze the liquid flowing in the flow path 2a of the tubular member 2 based on the moving distance and moving time of the liquid, and to calculate the viscosity of the liquid, etc. The analysis device 1 includes a sensor unit 3. The sensor unit 3 includes an image sensor 3b capable of capturing an image of the flow state of the liquid in the flow path 2a. The image sensor 3b is provided on the substrate 3a so as to be able to capture an image of at least a certain range of the tubular member 2. In the illustrated example, the sensor unit 3 is disposed on the upper side of the tubular member 2. Instead of the image sensor 3b, the sensor unit 3 may be configured to include a plurality of optical sensors provided at intervals along the length direction of the tubular member 2.

[0013] The analysis device 1 includes a terminal device 4 configured with a computer or the like. The terminal device 4 includes a calculation unit 5. The calculation unit 5 includes a computer in which software is installed that performs image processing such as binarization and shading of image data output from the image sensor 3b, and analyzes characteristics such as the flow speed and viscosity of the liquid based on the image-processed image data. If the image sensor 3b captures an image that can detect the end and direction of the tubular member 2 and the tip position of the flow of the liquid flowing through the flow path 2a, accurate positioning of the tubular member 2 is not required. If the calculation unit 5 calculates distance information from the image captured by the image sensor 3b from the inlet 2b of the tubular member 2, which is the flow path 2a, to the tip position of the flow of the liquid, characteristics such as the flow speed and viscosity of the liquid can be calculated with higher accuracy. The calculation unit 5 includes hardware such as a CPU, ROM, RAM, etc., for calculating characteristics such as the flow speed and viscosity of the liquid. The calculation unit 5 stores a program for calculating the flow speed and viscosity of the liquid, and is capable of executing the program. The display unit 6 is configured with a liquid crystal display or the like to display the calculation results of the calculation unit 5 and the driving state of the sensor unit 3. The terminal device 4 is not limited to being configured with one piece of hardware, and may be configured with multiple pieces of hardware. For example, the terminal device 4 may have the calculation unit 5 and the display unit 6 configured with different pieces of hardware.

[0014] The tubular member 2 is made of a transparent material having optical transparency, and is formed in a hollow, elongated shape having a flow path 2a with a small cross-sectional area (inner diameter) that generates a capillary phenomenon. This tubular member 2 may be a glass tube. If the tubular member 2 is a glass tube, the light irradiated toward the flow path 2a is more easily transmitted than in a tubular member 2 made of a transparent resin material, and it is possible to suppress the attenuation and scattering of light. In addition, if the tubular member 2 is a glass tube, it is easier to manufacture a flow path 2a with a small cross-sectional area (inner diameter). An opening on one side of the flow path 2a in the length direction of this tubular member 2 constitutes the receiving port 2b. The tubular member 2 is configured so that the liquid that is dropped into the dripping portion 9 and contacts the receiving port 2b can be introduced into the flow path 2a by the capillary phenomenon. In the illustrated example, the tubular member 2 is configured in a cylindrical shape.

[0015] As shown in FIG. 1(a), the analytical device member 7 is a member in which the receiving port 2b of the tubular member 2 is arranged above the dripping portion 9. The analytical device member 7 in the illustrated example is composed of a rectangular liquid-resistant sheet body 8. The sheet body 8 may be made of paper, resin, synthetic paper, waterproof paper, glass, etc., as long as it has liquid resistance. The sheet body 8 is preferably configured to have resistance to liquids in general, such as water resistance, oil resistance, and chemical resistance, as liquid resistance. In addition, the sheet body 8 may be configured so that the dimension along the length direction of the tubular member 2 is larger than the length dimension of the tubular member 2. With this configuration, the tubular member 2 arranged along the length direction of the sheet body 8 can be stably supported by the sheet body 8. In addition, the end of the tubular member 2 opposite to the receiving port 2b can also be placed on the sheet body 8. In addition, when the image sensor 3b is arranged on the lower side of the sheet body 8, an opening that penetrates the sheet body 8 in the thickness direction and is long in the length direction of the tubular member 2 may be provided so as to enable imaging of the tubular member 2, and the sheet body 8 may be made of a transparent material.

[0016] The dripping portion 9 is provided on one side of the sheet body 8 in the longitudinal direction. The dripping portion 9 may have any shape as long as it can surround the receiving port 2b of the tubular member 2 disposed above the dripping portion 9 in a plan view. The dripping portion 9 may be, for example, generally circular in plan view, or may be formed such that the side portion facing the receiving port 2b in the longitudinal direction in plan view is formed in an arc shape curved outward, and both side portions connected to both ends of this arc-shaped side portion are gradually narrowed toward the other side in the longitudinal direction of the sheet body 8, as shown in Figs. 1(a) to (c). The dripping portion 9 may be provided with a mark or the like that serves as a guide for the position where the receiving port 2b of the tubular member 2 is disposed. The dripping portion 9 is formed and is partitioned by a flow stopping portion 10 which protrudes upward from the periphery of the dripping portion 9 on one side of the sheet body 8 in the thickness direction.

[0017] The flow stopper 10 is not particularly limited in configuration as long as it is configured to suppress leakage of the liquid dripped on the dripping portion 9 to the outside. For example, as shown in Figs. 1(a) to (c), the flow stopper 10 may be a flow stopper wall surface 11 formed on the sheet body 8 so as to rise from the periphery of the dripping portion 9. With such a configuration, the dripping portion 9 and the flow stopper 10 can be integrally configured to effectively reduce the thickness. The flow stopper wall surface 11 is formed by deforming the sheet body 8 in the thickness direction. With such a configuration, the manufacturing of the flow stopper wall surface 11 can be simplified by pressing or the like. The method of deforming a part of the sheet body 8 in the thickness direction is not particularly limited, and may be vacuum molding, embossing by pressing a mold, or the like. In addition, when the sheet body 8 is a disposable member that is thrown away, the amount of waste can be effectively reduced compared to a configuration in which the flow stopper wall surface 11 is formed by stacking the sheet body. In the illustrated example, the flow stopper wall surface 11 is an inclined surface that slopes downward toward the dripping portion 9. In addition, in the example shown in the figure, the flow stopping wall 11 does not surround the entire circumference of the dripping portion 9 when viewed in a plane, and is configured to be connected to the movement suppression portion 12 (movement suppression wall 13) without surrounding a portion of the other side of the sheet body 8 in the longitudinal direction of the dripping portion 9.

[0018] The configuration of the movement suppressing portion 12 is not particularly limited as long as it is capable of suppressing the movement of the tubular member 2, but if the tubular member 2 is cylindrical, it may move by rolling, causing the receiving port 2b to come off the dripping portion 9. Therefore, it is preferable that the movement suppressing portion 12 is configured to suppress at least the movement in the length direction of the tubular member 2 and the width direction, which is a direction perpendicular to the direction along the thickness direction of the sheet body 8. Also, it is sufficient that the movement suppressing portion 12 is configured to suppress the movement of the tubular member 2 to such an extent that at least the receiving port 2b does not come off the dripping portion 9 in a plan view. In the illustrated example, the movement suppressing portion 12 is a movement suppressing wall surface 13, 13 formed on the sheet body 8 so as to rise on both sides in the width direction, which is a direction perpendicular to the length direction of the tubular member 2 and the thickness direction of the sheet body 8. With this configuration, it is possible to effectively reduce the thickness and suppress the movement of the tubular member 2 in the width direction, compared to a configuration having a base member provided with a void portion for accommodating the tubular member 2. In addition, the movement suppressing wall surface 13 is formed by deforming the sheet body 8 in the thickness direction. With this configuration, it is possible to simplify the manufacture of the movement suppressing wall surface 13 by pressing or the like. In addition, when the sheet body 8 is a disposable member that is thrown away, it is possible to effectively reduce the amount of waste, compared to a configuration in which the movement suppressing wall surface 13 is formed by stacking sheet bodies.

[0019] The movement suppression wall surfaces 13, 13 on both sides in the width direction of the tubular member 2 are formed so as to define an accommodating groove portion 13a that accommodates a part of one side in the length direction of the tubular member 2. The groove bottom of this accommodating groove portion 13a is configured to be flush with the drip portion 9. These movement suppressing wall surfaces 13, 13 are wall surfaces that are approximately parallel to the longitudinal direction of the tubular member 2 and inclined toward the center in the width direction of the tubular member 2. With this configuration, when the cylindrical tubular member 2 is disposed between the movement suppressing wall surfaces 13, 13, the inclination of the movement suppressing wall surfaces 13 acts as a guide that guides the tubular member 2 between the movement suppressing wall surfaces 13, 13, making it easier to assemble the tubular member 2.

[0020] The movement suppression wall surfaces 13, 13 on both sides are formed continuously from both side portions of the flow stopping wall surface 11 described above. At one end of the sheet body 8 in the length direction, a protruding portion 14 is provided that protrudes to one side in the thickness direction of the sheet body 8 so as to form the flow stopping wall surface 11 and the movement suppression wall surface 13. In other words, this protruding portion 14 is provided so as to partition the dripping portion 9 and the storage groove portion 13a. The surface of the sheet body 8 excluding this protruding portion 14 is configured to be flush with the dripping portion 9 and the storage groove portion 13a. Note that, in the illustrated example, an example is shown in which the outer shape of this protruding portion 14 in a plan view is substantially rectangular, but this is not limited to this example. The height dimensions (dimension along the thickness direction of the sheet body 8 from the dripping portion 9) of the flow stopping wall surface 11 and the movement suppressing wall surface 13 are formed to be approximately the same as each other. Also, in the illustrated example, the height dimensions of the flow stopping wall surface 11 and the movement suppressing wall surface 13 are formed to be equal to or less than the height dimension (outer diameter) of the tubular member 2. The flow stopping wall surface 11 may have any shape and dimension that can suppress leakage of the liquid dripped into the dripping portion 9 to the outside, and the movement suppressing wall surface 13 may have any shape and dimension that can suppress movement of the tubular member 2 in the width direction.

[0021] Next, other embodiments of the analytical device component will be described with reference to Figures 3(a) to (c) and 4(a) to (c). Note that in the following embodiments, differences from the previously described embodiments will be mainly described, and descriptions of configurations and effects of parts common to the previously described embodiments will be omitted.

[0022] 3(a) shows an analyzer member 7A according to a second embodiment. In this embodiment, the configuration of a sheet body 8A is different from that of the first embodiment. The sheet body 8A includes a first sheet body 15 constituting the dripping portion 9A, and a second sheet body 16 constituting the flow stopping wall surface 11A (flow stopping portion 10A) and laminated on the first sheet body 15. With this configuration, deformation of the flow stopping wall surface 11A due to a load in the thickness direction can be suppressed compared to a configuration in which the flow stopping wall surface is formed by deforming the sheet body in the thickness direction. In addition, the second sheet body 16 laminated on the first sheet body 15 constitutes the movement suppressing wall surface 13A (movement suppressing portion 12A). With this configuration, it is possible to suppress deformation of the movement suppressing wall surface 13A due to a load in the thickness direction, compared to a configuration in which the movement suppressing wall surface is formed by deforming the sheet body in the thickness direction. The first sheet body 15 and the second sheet body 16 may be laminated and fixed by pressure bonding, adhesive, or the like.

[0023] The first sheet body 15 and the second sheet body 16 are both rectangular sheet bodies that are liquid-resistant. The first sheet body 15 and the second sheet body 16 may be configured to have different outer shapes in a plan view. In the illustrated example, the first sheet body 15 and the second sheet body 16 have approximately the same width dimension, but different length dimensions. The first sheet body 15 has a length dimension that is greater than the length dimension of the tubular member 2. On the other hand, the second sheet body 16 has a length dimension that is smaller than the length dimension of the first sheet body 15 and smaller than the length dimension of the tubular member 2. At one end of the second sheet body 16 in the length direction, a through hole 16a is provided that penetrates in the thickness direction to expose the dripping portion 9A of the first sheet body 15. In the illustrated example, the through hole 16a is substantially rectangular in plan view. The portion of the first sheet body 15 exposed in the through hole 16a constitutes the dripping portion 9A. The inner peripheral surface of the through hole 16a constitutes the flow-stopping wall surface 11A. The second sheet body 16 is provided with a slit portion 16b that extends in the length direction of the second sheet body 16 so as to communicate with the through hole 16a and open at the end face on the other side in the length direction, penetrating the thickness direction. Both inner walls in the width direction of the slit portion 16b constitute the movement suppression wall surfaces 13A on both sides in the width direction of the tubular member 2. The slit portion 16b is formed to have a width dimension smaller than the width dimension of the through hole 16a and approximately the same as or slightly larger than the width dimension of the tubular member 2.

[0024] The thickness dimension of the second sheet body 16 may be an appropriate dimension so that the flow-stopping wall surface 11A formed by laminating it on the first sheet body 15 can prevent the liquid from leaking to the outside, and so that the movement of the tubular member 2 in the width direction can be prevented by the movement-suppressing wall surface 13A formed by laminating it on the first sheet body 15. Alternatively, the first sheet body 15 may be configured to be hydrophilic, and the second sheet body 16 may be configured to be water-repellent (hydrophobic). With such a configuration, when the liquid is water-soluble, the liquid dripped onto the drip portion 9A of the first sheet body 15 is more likely to spread over the drip portion 9A and reach the receiving port 2b, and leakage of the liquid that has reached the flow-stopping wall surface 11A of the second sheet body 16 to the outside can be more effectively suppressed.

[0025] 3(b) shows an analyzer component 7B according to a third embodiment. In this embodiment, the configuration of a movement suppressing portion 12B is different from that of the above-described embodiments. The movement suppressing portion 12B is an adhesive material 17 laminated on the sheet body 8B (in this embodiment, a first sheet body 15A described later). With this configuration, when the tubular member 2 is assembled, the tubular member 2 can be fixed to the adhesive material 17, and the assembly of the tubular member 2 can be facilitated. The sheet body 8B is composed of a first sheet body 15A and a second sheet body 16A laminated thereon. The first sheet body 15A and the second sheet body 16A are configured to have substantially the same rectangular outer shape in plan view. The first sheet body 15A and the second sheet body 16A are longer than the tubular member 2. A circular first through hole 16Aa is formed at one end of the second sheet body 16A in the length direction, exposing the dripping portion 9B of the first sheet body 15A. The inner circumferential surface of the first through hole 16Aa constitutes the flow stopping wall surface 11B (flow stopping portion 10B). The dripping portion 9B of this embodiment is configured to be surrounded by the flow stopping wall surface 11B all around.

[0026] The second sheet body 16A is provided with a second through hole 16Ab in which the adhesive material 17 laminated to the first sheet body 15A is disposed. With this configuration, it is possible to reduce the step between the second sheet body 16A and the adhesive material 17, even though the configuration includes the adhesive material 17. In the illustrated example, the second through hole 16Ab is formed in a shape that matches the adhesive material 17. The adhesive material 17 is an adhesive tape with an adhesive layer laminated on the upper surface, and a plurality of adhesives (two in the illustrated example) are provided at intervals in the length direction of the first sheet body 15A. The adhesive material 17 may be a double-sided adhesive tape with adhesive layers provided on both sides in the thickness direction and fixed to the first sheet body 15A. The adhesive material 17 is laminated on the first sheet body 15A so as to extend along the width direction of the first sheet body 15A, and is disposed in the second through-hole 16Ab of the second sheet body 16A so as to be approximately flush with the upper surface of the second sheet body 16A. The adhesive material 17 may be provided so as to protrude above the upper surface of the second sheet body 16A. The tubular member 2 is placed on the adhesive material 17 and fixed by the adhesive layer of the adhesive material 17. This makes it possible to suppress the movement of the tubular member 2. The adhesive material 17 may be configured such that a release paper that can be peeled off from the adhesive layer is laminated on the adhesive material 17. With this configuration, when the tubular member 2 is placed on the analytical device member 7B, the release paper can be peeled off and the tubular member 2 can be used. Furthermore, until the tubular member 2 is placed, the release paper protects the adhesive layer of the adhesive material 17, thereby preventing a decrease in the adhesive strength of the adhesive material 17.

[0027] 3(c) shows an analyzer member 7C according to a fourth embodiment. In this embodiment, the configuration of a flow stopper 10C is different from that of the above-described embodiments. The flow stopping portion 10C is provided on the same surface of the sheet body 8C so as to be substantially flush with the dripping portion 9C. The dripping portion 9C and the flow stopping portion 10C are formed by surface treatment on the upper surface of the sheet body 8C so that the contact angles with the liquid are different from each other, and the dripping portion 9C is configured to have a smaller contact angle with the liquid than the flow stopping portion 10C. The dripping portion 9C is formed in a substantially circular shape in a plan view, and the flow stopping portion 10C is formed to surround the entire periphery of the dripping portion 9C. With this configuration, the liquid that spreads over the dripping portion 9C and reaches the boundary portion with the flow stopping portion 10C is less likely to flow toward the flow stopping portion 10C, which has a larger contact angle with the liquid than the dripping portion 9C, and leakage of the liquid to the outside can be suppressed. Note that the upper surface of the sheet body 8C may be configured as the flow stopping portion 10C by making the contact angle with the liquid larger than that of the dripping portion 9C.

[0028] The contact angle of the dripping portion 9C with the liquid is preferably 45 degrees or less, and the contact angle of the flow stopper 10C with the liquid is preferably 100 degrees or more. The contact angles of the dripping portion 9C and the flow stopper 10C with the liquid can be measured in accordance with the wettability test method for substrate glass surfaces specified in JIS R 3257:1999. The dripping portion 9C may be hydrophilic, and the flow stopper 10C may be water repellent (hydrophobic). With such a configuration, when the dripped liquid is water-soluble, the liquid dripped on the dripping portion 9C spreads easily over the dripping portion 9C and reaches the receiving port 2b of the tubular member 2, and the liquid that reaches the boundary with the flow stopper 10C can be more effectively prevented from leaking to the flow stopper 10C side. The analytical device member 7C may be provided with a marking portion for the dripping portion 9C that serves as a guide for the position to drip the liquid. As the marking portion of dripping portion 9C, for example, the range of dripping portion 9C may be indicated by a line or the like, or the color of dripping portion 9C may be made different from the surroundings, etc. Furthermore, the configuration of dripping portion 9C and flow stopping portion 10C is not limited to the above-mentioned configuration, and may be, for example, a configuration in which a separate sheet body constituting dripping portion 9C, which has a shape that matches with a hole provided in sheet body 8C and has a smaller contact angle with the liquid than the surrounding area of ​​the hole, is fitted into the hole.

[0029] A plurality of (two in the illustrated example) adhesive materials 17, 17 constituting the movement suppression portion 12C are laminated on the sheet body 8C at intervals in the longitudinal direction. In the illustrated example, a rectangular opening 8Ca penetrating the sheet body 8C in the thickness direction and extending in the longitudinal direction is provided between the two adhesive materials 17, 17. By disposing the tubular member 2 above this opening 8Ca, even if the sheet body 8C is opaque, the image sensor 3b installed below the sheet body 8C can capture an image of the tubular member 2 through the opening 8Ca.

[0030] FIG. 4(a) shows an analysis device member 7D according to the fifth embodiment. In this embodiment, a sheet body 8D is provided with a base member 18 having a storage recess 18c disposed on a bottom portion 18a. With this configuration, even if liquid leaks from the sheet body 8D, it remains in the storage recess 18c, and leakage of the liquid to the outside can be effectively suppressed. Furthermore, if the storage recess 18c is formed to a size capable of storing the entire sheet body 8D and the tubular member 2, when liquid is discharged from the end of the tubular member 2 opposite to the receiving port 2b, the liquid remains in the storage recess 18c, and leakage of the liquid to the outside can be more effectively suppressed.

[0031] The base member 18 has a rectangular bottom 18a in plan view and a wall 18b formed to rise from the outer periphery of the bottom 18a. The bottom 18a and the wall 18b define an accommodation recess 18c that opens upward. The base member 18 is preferably configured to be liquid-resistant, and may be made of resin or glass. The base member 18 may also be configured of a transparent material. The base member 18 may be configured to be reusable.

[0032] The sheet body 8D is provided with a flow stopper 10D formed by deforming the sheet body 8D in the thickness direction. The flow stopper 10D is provided at one end of the sheet body 8D in the length direction so as to surround the periphery of the dripping part 9D, which is circular in plan view, and is formed in a substantially C-shaped arc shape in plan view. The inner wall surface of this flow stopper 10D constitutes the flow stopper wall surface 11C. In addition, both ends of the flow stopper 10D in the circumferential direction are close to each other via a gap. The wall surfaces of both ends of the flow stopper 10D in the circumferential direction may function as movement suppression wall surfaces.

[0033] The sheet body 8D is provided with a movement suppressing portion 12D formed by deforming the sheet body 8D in the thickness direction. The movement suppressing portion 12D is formed at an interval in the length direction of the sheet body 8D from the flow stopping portion 10D. The sheet body 3D is formed with two pairs of movement suppressing portions 12D formed to rise on both sides in the width direction of the tubular member 2 and spaced apart from each other in the length direction of the tubular member 2. The wall surface of each of these movement suppressing portions 12D on the tubular member 2 side becomes the movement suppressing wall surface 13B.

[0034] 4(b) shows an analyzer member 7E according to a sixth embodiment. In this embodiment, the configuration of a movement suppressing part 12E is different from that of the above-described embodiments. The movement suppressing portion 12E is not provided on the sheet body 8E, but on the base member 18A. With this configuration, the movement of the tubular member 2 can be suppressed by the movement suppressing portion 12E of the base member 18A, so that the sheet body 8E can be configured without providing a movement suppressing portion, and the configuration of the sheet body 8E can be simplified. The dimension of sheet body 8E along the length direction is smaller than the length dimension of tubular member 2, and the end opposite to receiving port 2b is not placed on sheet body 8E.

[0035] The base member 18A is configured as a rectangular plate whose length direction is aligned with the length direction of the tubular member 2. An accommodation recess 18Ac that is rectangular in plan view and opens upward is formed at one end of the base member 18A in the length direction. A wall portion 18Ab that defines the periphery of the accommodation recess 18Ac may form the flow stopper portion 10E. A first accommodation groove portion 18Ad that is connected to the accommodation recess 18Ac and opens upward, and is provided on the other side of the accommodation recess 18Ac in the length direction, is formed in the base member 18A. The first accommodation groove portion 18Ad has a groove width dimension corresponding to the width dimension of the tubular member 2, and both groove walls form the movement suppression portion 12E.

[0036] The base member 18A has an opening 18Ae formed on the other side of the first housing groove 18Ad in the length direction, and communicating with the first housing groove 18Ad and penetrating the base member 18A in the thickness direction. The opening 18Ae is formed to extend in the length direction of the tubular member 2. The width dimension of the opening 18Ae is configured to be larger than the width dimension of the tubular member 2. When the image sensor 3b is installed on the lower side of the base member 18A, the image sensor 3b can image the liquid flowing in the flow path 2a of the tubular member 2 arranged in the opening 18Ae. At this time, since the image sensor 3b is installed on the lower side of the base member 18A, the receiving port 2b of the tubular member 2 cannot be imaged. However, if information on the length of the tubular member 2 is stored in the calculation unit 5, the position of the receiving port 2b can be specified by detecting the other end of the tubular member in the length direction, and the characteristics such as the flow speed and viscosity of the liquid can be calculated more accurately. The base member 18A is formed with a second housing groove 18Af that is connected to the opening 18Ae, opens upward, and is provided on the other side of the opening 18Ae in the longitudinal direction. The second housing groove 18Af is configured substantially similarly to the first housing groove 18Ad, and its groove wall constitutes the movement suppressing portion 12E. The end portion on the other side of the longitudinal direction of the base member 18A is shaped to extend in two directions from the second housing groove 18Af in a plan view along the longitudinal direction, and may be formed longer than the portion of the tubular member 2 that protrudes from the second housing groove 18Af.

[0037] The sheet body 8E is appropriately shaped so as to be able to be accommodated in the accommodation recess 18Ac, and its upper surface is configured as a dripping portion 9E. The sheet body 8E may be arranged so as not to come into contact with the wall portion 18Ab surrounding the accommodation recess 18Ac, and the bottom portion 18Aa may be exposed on the outer periphery of the sheet body 8E in a plan view. With such a configuration, a step-down portion 19 (bottom portion 18Aa) is configured so as to surround the dripping portion 9E (sheet body 8E) and to be stepped downward with respect to the dripping portion 9E. Since cohesive energy acts on the liquid, and a force acts to reduce the surface area, when the liquid is dripped into the dripping portion 9E and tries to spread, when it reaches the outer periphery of the dripping portion 9E, it tries to maintain the droplet shape without exceeding the outer periphery, and thus the diffusion is suppressed. If the contact angle with the liquid is too small, the liquid will easily spread beyond the outer periphery, and if the contact angle with the liquid is too large, the liquid may turn into droplets and roll off the outer periphery, so it is preferable to set the contact angle with the liquid to about 60 degrees to 120 degrees to suppress the diffusion of the liquid. If the sheet body 8E having a moderate contact angle with the liquid is arranged so as not to contact the wall portion 18Ab surrounding the accommodation recess 18Ac, the outer periphery of the sheet body 8E, which is the drip portion 9E, acts as a flow stopper in addition to the flow stopper 10E. Note that the sheet body 8E may be configured to have a drip portion and a flow stopper configured by making the contact angles with the liquid different from each other, similar to the sheet body 8F in the seventh embodiment described later.

[0038] 4(c) shows an analyzer member 7F according to the seventh embodiment. In this embodiment, the accommodating recess 18Bc of the base member 18B extends along the length of the tubular member 2, and is configured such that the central portion in the length direction is smaller inward in the width direction than the end portions in the length direction. The receiving recess 18Bc is defined by a bottom 18Ba and a wall 18Bb formed to rise from the outer peripheral edge of the bottom 18Ba, and opens upward. In the base member 18B, the inner wall surfaces of the wall 18Bb on both sides facing each other in the width direction of the central portion in the length direction, which are close to each other, are configured as the movement suppressing portions 12F, 12F. In the illustrated example, the dimension between the movement suppressing portions 12F, 12F is larger than the width dimension of the tubular member 2. The dimension between the movement suppressing portions 12F, 12F may be equal to or smaller than the width dimension of the dripping portion 9F. With this configuration, when the dripping portion 9F is arranged so that its widthwise center approximately coincides with the widthwise center between the movement suppressing portions 12F, 12F, even if the tubular member 2 rolls and moves in the width direction, it comes into contact with the movement suppressing portion 12F, and the receiving opening 2b can be prevented from coming off the dripping portion 9F in a plan view. Furthermore, the dimension between the movement suppressing portions 12F, 12F may be an appropriate dimension capable of holding the tubular member 2 disposed on the bottom portion 18Ba from both sides in the width direction.

[0039] The sheet body 8F is formed in a rectangular shape in a plan view, and is provided on its upper surface with a dripping portion 9F that is circular in a plan view, and a flow stopping portion 10F that surrounds the entire circumference of the circular dripping portion 9F and is configured to have a larger contact angle with the liquid than the dripping portion 9F. As in the fourth embodiment described above, the sheet body 8F may be provided on the same surface of the sheet body 8F such that the flow stopping portion 10F and the dripping portion 9F are substantially flush with each other. In this embodiment, the sheet body 8F is configured such that the dimension along the length direction of the tubular member 2 is smaller than the length dimension of the tubular member 2.

[0040] The different configurations described in the above embodiments may be modified, rearranged, or combined as necessary. In addition, the sheet members 8, 8A to 8F and the base members 18, 18A, and 18B may have marks such as length marks or square marks on the surface facing the image sensor 3b to facilitate calculation of the flow speed of the liquid by image processing. In addition, the base members 18, 18A, and 18B may have marks or the like to serve as a guide for the position of the sheet members 8, 8A to 8F and the tubular member 2. [Explanation of symbols]
