Description

  The present invention relates to a liquid component measurement cartridge, a liquid component measurement device, and a liquid component measurement system that measure liquid components such as urine.

  For example, a measuring device that collects a liquid such as urine or saliva and measures a specific component is known. The measurement apparatus of Patent Document 1 is a measurement kit that measures amylase from a liquid such as saliva. This measurement kit includes a carrier that is slidably inserted into a holder, and a liquid (specimen) is absorbed and collected by a collection unit provided at the tip of the carrier. Since the holder is provided with a test piece (reagent holding part) for holding the reagent, the carrier is slid with respect to the holder so that the sampling part faces the test piece, and then the holder is pressed from the outside to collect The sampling part is brought into contact with the test piece by pressing the part against the test piece. Thereby, the reagent of a test piece reacts with the liquid of a collection part, and amylase in a liquid is measured.

Japanese Patent No. 4283634

  However, in the technique of Patent Document 1, the collected liquid cannot be absorbed by the test piece unless the collection part is pressed against the test piece. Therefore, in the technique of Patent Document 1, in order to absorb the collected liquid into the test piece, it is necessary to perform an operation of pressing the holder against the test piece by pressing the holder from the outside after sliding the carrier with respect to the holder. As a result, the operation becomes complicated.

  In view of the above circumstances, an object of the present invention is to solve the problem of facilitating the absorption of a collected liquid into a test piece while simplifying the operation.

  One aspect of the cartridge for measuring a liquid component according to the present invention is a slide sheet having a collection portion having a recess for collecting a liquid, a test piece for measuring a component in the liquid, and the slide sheet is slidable And a holding body that is held so that the test piece is exposed to the insertion path. According to this aspect, since the collection unit has the recess, the liquid that has come into contact with the collection unit enters the recess and is easily retained as a droplet. For this reason, the slide sheet is slid with respect to the holding body, and the sampling part is inserted to the position where the test piece is exposed to the insertion path, and the sampling part is held by the sampling part without being pressed against the test piece. Liquid droplets are easily absorbed by the test piece. Therefore, since the operation of pressing the sampling part against the test piece is unnecessary, the measurement operation can be simplified. Thus, according to this aspect, the collected liquid can be easily absorbed by the test piece while simplifying the measurement operation.

  In one embodiment of the above-described invention, at least a surface of the slide sheet having a concave portion of the collection portion has water repellency. According to this aspect, since the liquid that has contacted the collection unit is not absorbed by the collection unit and easily moves to the recess, a larger amount of liquid can be held. Furthermore, small droplets are gathered together by the surface tension and become large droplets and are easily held. Thereby, the effect which makes it easy to make the test piece absorb the droplet of the liquid hold | maintained at the collection | recovery part can be heightened.

  In one aspect of the invention described above, the holding body is formed with a measurement window for measuring the test piece from the outside of the holding body on the side opposite to the insertion path as viewed from the test piece. According to this aspect, since the measurement window for measuring the test piece from the outside of the holding body is formed on the side opposite to the insertion passage when viewed from the test piece, it is not necessary to pull out the slide sheet from the insertion passage. The test piece can be measured from the outside of the holding body. Thereby, operation can be simplified compared with the case where operation which pulls out a slide sheet from an insertion path is required.

  In one aspect of the invention described above, the holding body is formed by stacking the first sheet and the second sheet, an insertion path is formed between the first sheet and the second sheet, and a test piece is formed on the second sheet. The first sheet has a shorter depth than the second sheet, as viewed from the slide sheet collecting portion side, and the leading edge of the first sheet viewed from the slide sheet collecting portion side is the second sheet It is in a position retracted from the tip. According to this aspect, the first sheet has a shorter depth than the second sheet, as viewed from the slide sheet collecting portion side, and the leading edge of the first sheet as viewed from the slide sheet collecting portion side is the second sheet. Therefore, a portion that does not overlap the first sheet can be provided on the front end side of the second sheet. By comprising in this way, the part extended from the front-end | tip of a 1st sheet | seat among the slide sheets penetrated by the insertion path becomes easy to bend in the direction away from a 2nd sheet | seat. Therefore, the slide sheet collecting part is easily inserted into the insertion path from the front end of the first sheet without contacting the front end of the second sheet. Thereby, it becomes easy to insert the liquid of the collection part into the insertion passage without being repelled at the tip of the second sheet.

  1 aspect of the invention mentioned above WHEREIN: A slide sheet is provided with the control part which controls that a slide sheet slips out from a holding body to the collection part side. According to this aspect, even if the slide sheet is pulled by mistake, for example, it is possible to restrict the slide sheet from coming off from the holding body to the collection unit side by the regulating unit.

  In one embodiment of the invention described above, the holding body, the slide sheet, and the test piece are formed of a water-soluble material or a water-decomposable material.

Is provided. According to this aspect, when the liquid component measurement cartridge is placed at a predetermined position on the base and the lid is closed so that the through hole of the slide sheet is inserted into the protrusion of the operation element, the operation element slides. The sheet can be slid. According to this, compared with the case where the liquid component measuring cartridge is inserted into the liquid component measuring device and then the protrusion of the operation element is inserted into the through hole of the slide sheet, the protrusion of the operation element penetrates the slide sheet. It can be reliably inserted into the hole.

  In one aspect of the invention described above, the through hole of the slide sheet is a long hole that is long in the direction along the slide direction of the slide sheet. According to this aspect, since the through hole of the slide sheet is long in the sliding direction of the slide sheet, the through hole of the slide sheet can be easily inserted into the protrusion of the operation element even if the slide sheet is slightly shifted in the sliding direction.

  Hereinafter, a liquid component measuring device and a liquid component measuring cartridge according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a liquid component measurement cartridge 20 equipped with a liquid component measurement device 10 according to this embodiment. FIG. 2 is an external configuration diagram of the liquid component measurement cartridge. 1 and 2, a direction in which a slide sheet 30 described later slides is defined as an X direction, and a direction perpendicular to the X direction is defined as a Y direction. The Z direction is a direction perpendicular to the XY plane. The X direction, the Y direction, and the Z direction are indicated by arrows, the direction of the arrow is the positive side, and the opposite side is the negative side (the same applies to other drawings).

  The liquid component measuring device 10 and the liquid component measuring cartridge 20 of this embodiment constitute a liquid component measuring system. In the liquid component measurement system of the present embodiment, a liquid (specimen) such as urine or saliva is collected by the liquid component measurement cartridge 20, and the components in the collected liquid are measured by the liquid component measurement device 10. The liquid component measuring cartridge 20 is detachably attached to the liquid component measuring apparatus 10. When collecting urine and measuring components in urine, the liquid component measurement cartridge 20 functions as a urine component measurement cartridge, and the liquid component measurement device 10 functions as a urine component measurement device.

  As shown in FIG. 2, the liquid component measurement cartridge 20 includes a slide sheet 30 and a holding body 40. A test piece M is held inside the holding body 40. The components (slide sheet 30, holder 40, test piece M) of the liquid component measurement cartridge 20 of the present embodiment are made of water-soluble material or water-degradable material such as paper, PVA (polyvinyl alcohol) film, for example. Yes. Therefore, the used liquid component measurement cartridge 20 for collecting urine and the like can be removed from the liquid component measurement device 10 and discarded together with the liquid component measurement cartridge 20 in a toilet or the like, so that it can be flown as it is. Hygienic.

  The slide sheet 30 has a long shape extending in the X direction, and is inserted into the holding body 40 so as to be slidable in the X direction. One end portion (end portion on the negative side in the X direction) and the other end portion (end portion on the positive side in the X direction) in the longitudinal direction of the slide sheet 30 protrude from the holding body 40. At one end in the longitudinal direction of the slide sheet 30, a collection unit 32 that collects liquid such as urine is provided.

  The other end of the slide sheet 30 in the longitudinal direction (the end opposite to the collection unit 32 when viewed from the holding body 40) is restricted from coming out of the slide sheet 30 from the holding body 40 toward the collection unit 32. A restriction unit 34 is provided. For example, as shown in FIG. 2, the restricting portion 34 is a rectangular portion configured to be wider than the width (width in the Y direction) of the portion through which the slide sheet 30 is inserted into the holding body 40. Thereby, for example, even if the slide sheet 30 is accidentally pulled to the collection unit 32 side (the negative side in the X direction), the regulating unit 34 is caught by the holding body 40, so that the slide body 30 slides to the collection unit 32 side. It can control that sheet 30 comes off. The restricting portion 34 may be configured integrally with the slide sheet 30 or may be configured separately.

  A test piece M is held inside the holding body 40. The test piece M contains a reagent that reacts with components in a liquid such as urine collected by the collection unit 32. Examples of the reagent include a reagent whose color changes according to the concentration of a component in urine (for example, urine sugar value). The change in the color of the test piece M includes, for example, a case where at least one of hue, saturation, and brightness changes. Note that the test piece M is not limited to a reagent for measuring components in urine, and can be one containing various reagents for measuring various components in the collected liquid.

  The holding body 40 is formed with a measurement window 482 for measuring the test piece M from the outside of the holding body 40. Accordingly, since the test piece M can be measured from the outside of the holding body 40 through the measurement window 482, the test piece M is measured by the liquid component measurement device 10 while the liquid component measurement cartridge 20 is mounted on the liquid component measurement device 10. be able to. In addition, since the color change of the test piece M can be observed visually through the measurement window 482, the component in the liquid can be measured with the liquid component measuring cartridge 20 alone.

  A liquid component measuring cartridge 20 is detachably attached to the liquid component measuring apparatus 10 according to the present embodiment. Specifically, as shown in FIG. 1, the liquid component measuring apparatus 10 includes a rectangular base portion 11 and a lid portion 12. The lid 12 is attached to the base 11 so that it can be opened and closed.

  As shown in FIG. 1, the liquid component measurement cartridge 20 is placed at a predetermined position of the base 11, and the liquid is measured so that the sampling part 32 of the slide sheet 30 protrudes outside the base 11 (the negative side in the X direction). A component measuring cartridge 20 is mounted between the base 11 and the lid 12. According to this, the liquid component measurement cartridge 20 is placed in a predetermined position on the base 11 and the lid 12 is closed, so that the liquid component measurement cartridge 20 is always placed in a predetermined position in the liquid state. It can be attached to the component measuring apparatus 10. The lid portion 12 may be configured to be removable from the base portion 11 and any one of the four side surfaces of the base portion 11 (for example, the positive side surface in the X direction and the positive or negative side surface in the Y direction). The lid portion 12 may be pivotally supported so that the lid portion 12 can be opened and closed without being detached from the base portion 11. Specifically, for example, a groove hole is provided on the base 11 side, and a shaft-like protrusion that engages with the groove hole is provided on the lid 12 side, so that the groove on the base 11 side has a shaft shape on the lid 12 side. The protrusion is engaged and pivotally supported.

  FIG. 3 is a view of the base 11 of the liquid component measuring apparatus 10 as viewed from above (Z direction). As shown in FIG. 3, the liquid component measuring device 10 is configured so that the liquid component measuring cartridge 20 is located on the base 11 so that the sampling portion 32 on one end side of the slide sheet protrudes from the base 11. It is placed at a predetermined position. Specifically, a mounting portion 112 that positions the liquid component measurement cartridge 20 at a predetermined position is formed on the base 11. The mounting portion 112 includes a recess that can be inserted while guiding the outer diameter of the holding body 40. When the holding body 40 is inserted into the recess of the mounting portion 112, the holding body 40 is fixed in the liquid component measuring apparatus 10 by closing the lid portion 12.

  On the other hand, the slide sheet 30 can slide in the liquid component measuring apparatus 10 by moving the operation element 14 in the direction of the arrow (the positive side in the X direction). By moving the operation element 14 in the direction of the arrow, the sampling part 32 of the slide sheet 30 can be slid to a position facing the test piece M, so that the sliding operation can be simplified. A specific configuration using this operator is as follows.

  As shown in FIG. 1, the liquid component measuring apparatus 10 includes an operation element 14 that slides a slide sheet 30 with respect to a holding body 40. 1 illustrates the case where the operation element 14 is provided on the outside of the side surface of the liquid component measuring apparatus 10 so as to be slidable in the X direction. However, the present invention is not limited thereto, and the lower surface and the upper surface of the liquid component measuring apparatus 10 are not limited thereto. It may be provided on the outside so as to be slidable in the X direction.

  As shown in FIGS. 2 and 3, the operation element 14 includes a protrusion 142. Specifically, the operation element 14 includes an extension part 144 that extends into the liquid component measuring apparatus 10, and a protrusion 142 is provided at the tip of the extension part. On the other hand, a through hole 342 into which the protruding portion 142 of the operation element 14 is inserted is formed in the regulating portion 34 on the other end side of the slide sheet 30. For example, the through hole 342 is a long hole that is long in the direction along the sliding direction of the slide sheet 30.

  As shown in FIGS. 1 and 2, the protrusion 142 of the operation element 14 protrudes from the upper surface of the base 11 (the surface on which the liquid component measurement cartridge 20 is placed). When the liquid component measurement cartridge 20 is placed on the base 11, the protrusion 142 of the operation element 14 is inserted into the through hole 342 of the slide sheet 30. That is, if the liquid component measurement cartridge 20 is placed at a predetermined position of the base 11 and the lid 12 is closed so that the through hole 342 of the slide sheet 30 is inserted into the protrusion 142 of the operation element 14, The slide sheet 30 can be slid by the child 14. As a result, the protrusion of the operation element 14 is compared with the case where the protrusion 142 of the operation element 14 is inserted into the through hole 342 of the slide sheet 30 after the liquid component measurement cartridge 20 is inserted into the liquid component measurement apparatus 10. 142 can be reliably inserted into the through hole 342 of the slide sheet 30.

  Further, since the through hole 342 is a long hole that is long in the sliding direction of the slide sheet 30, the through hole 342 of the slide sheet 30 can be easily inserted into the protrusion 142 of the operation element 14 even if the slide sheet 30 is slightly displaced in the sliding direction. Can be made. In the present embodiment, the case where the through hole 342 is formed in the restricting portion 34 is illustrated, but the present invention is not limited to this, and the other end side of the slide sheet 30 protruding from the holding body 40 (with the sampling portion 32) It may be provided at any position on the opposite end side.

  The slide sheet 30 of the present embodiment is provided with a restricting portion (first restricting portion) 34 that restricts the slide sheet 30 from being removed from the holding body 40 to the sampling portion 32 side. For example, as shown in FIGS. 2 and 3, a restricting portion (second restricting portion) 36 may be further provided between the restricting portion 34 and the holding body 40. Specifically, the regulating portion 36 is configured by a fold line provided on the positive side in the X direction of the holding body 40 in the slide sheet 30. As described above, in the present embodiment, the slide sheet 30 is prevented from coming off from the holding body 40 toward the collection unit 32 by both the wide restricting portion 34 and the restricting portion 36 formed of folds. According to this, even if the slide sheet 30 is pulled to the collection unit 32 side, it is regulated that the slide sheet 30 is pulled out of the holding body 40 by the regulation by the regulation unit 36. Even if it enters the holding body 40, the restriction portion 34 can restrict the slide sheet 30 from coming out of the holding body 40 toward the collection portion 32.

  Further, since the restricting portion 36 is constituted by a fold provided on the positive side in the X direction of the holding body 40, the slide sheet 30 with respect to the holding body 40 when the liquid component measuring cartridge 20 is placed on the base 11. Can also be prevented from moving to the negative side in the X direction. That is, the fold line of the regulating portion 36 of the slide sheet 30 is caught by the holding body 40, and the slide sheet 30 can be made difficult to move to the negative side in the X direction. At this time, even if the slide sheet 30 is displaced in the positive direction of the X direction with respect to the holding body 40, the finger is applied to the fold of the restricting portion 36 or the wide portion of the restricting portion 34 and pulled to the negative side in the Z direction. Thus, the slide sheet 30 can be easily slid with respect to the holding body 40, and therefore, the slide sheet 30 can be easily returned to a predetermined position.

  4 is a diagram showing a schematic configuration in the liquid component measuring apparatus 10, and is a cross-sectional view taken along the line IV-IV of the liquid component measuring apparatus 10 shown in FIG. As shown in FIG. 4, a circuit board 15 is provided on the lid 12 of the liquid component measuring apparatus 10. The display unit 13 is mounted on the upper surface (the negative surface in the Z direction) of the circuit board 15. On the lower surface (the positive surface in the Z direction) of the circuit board 15, a control unit (control circuit) 16 that controls the liquid component measuring device 10 and a component for optically measuring components in the liquid from the test piece M are provided. A light emitting unit 17 and a light receiving unit 18 are attached.

  The light emitting unit 17 includes a light emitting element (for example, a light emitting diode) that emits light toward the test piece M of the liquid component measuring cartridge 20. The light receiving unit 18 includes a light receiving element that receives reflected light from the test piece M. The control unit 16 measures the component in the liquid based on the reflected light from the test piece M received by the light receiving unit 18 and displays the result on the display unit 13.

  For example, when measuring the urine sugar value in urine, the control unit 16 gives a relational expression between the reflectance of the reflected light (the ratio of the reflected light intensity of the light receiving unit 18 to the emission intensity of the light emitting unit 17) and the urine sugar value. Store in advance. This relational expression is a mathematical expression representing an approximate curve obtained from a calibration curve obtained in advance through experiments or the like. The control part 16 calculates | requires the reflectance of the reflected light from the test piece M, and calculates | requires the urine sugar value corresponding to the reflectance from a relational expression. Instead of storing in advance a relational expression representing the correspondence between the reflectance and the urine sugar value, a data table representing the correspondence between the reflectance and the urine sugar value is recorded in advance. The urine sugar value may be obtained from the above.

  As shown in FIG. 4, the light emitting unit 17 of the present embodiment is arranged to emit light toward the test piece M from the side opposite to the insertion path 422 when viewed from the test piece M of the liquid component measurement cartridge 20. Yes. According to such a configuration, even if the slide sheet 30 is inserted into the insertion passage 422, light can be applied to the test piece M. Therefore, while the liquid component measurement cartridge 20 is mounted on the liquid component measurement apparatus 10, The component in the liquid can be measured based on the reflected light from the test piece M without extracting the slide sheet 30 from the insertion path 422.

  In this embodiment, the liquid component measurement cartridge 20 is closed to the base 11 by closing the lid 12 with the liquid component measurement cartridge 20 placed on the base 11 of the liquid component measurement apparatus 10. Mounted between the parts 12. In this way, the liquid component measurement cartridge 20 is mounted on the liquid component measurement device 10, and the slide sheet 30 can be slid by the operation element 14.

  In this state, a liquid such as urine is applied to the collection unit 32 of the liquid component measurement cartridge 20 so that the collection unit 32 collects the liquid. Then, by sliding the slide sheet 30 in the X direction by the operation element 14, the collection unit 32 is inserted into the holding body 40, and the liquid collected by the collection unit 32 is brought into contact with the test piece M and absorbed. Thereby, the test liquid of the test piece M reacts with the component of a liquid, and a color changes. By receiving the reflected light when the test piece M emits light from the light emitting unit 17 by the light receiving unit 18, the liquid component is measured by the control unit 16 and displayed on the display unit 13. According to the configuration of the present embodiment, the component in the liquid is measured based on the reflected light from the test piece M by the control unit 16 while the liquid component measuring cartridge 20 is attached to the liquid component measuring apparatus 10. it can.

  Hereinafter, the specific configuration of the liquid component measurement cartridge 20 will be described in more detail. FIG. 5 is an exploded perspective view of the liquid component measuring cartridge 20, and FIG. 6 is a cross-sectional view of the liquid component measuring cartridge 20 shown in FIG.

  As shown in FIGS. 5 and 6, the holding body 40 is formed by overlapping the first sheet 42 and the second sheet 44, and the insertion path 422 of the slide sheet 30 is interposed between the first sheet 42 and the second sheet 44. And the test piece M is held on the second sheet 44.

  Specifically, the first sheet 42 includes spacers 424 for forming the insertion passages 422, and the spacers 424 are provided on both sides of the first sheet 42 along the sliding direction. It is joined to the lower surface of the sheet 44. Thereby, the upper surface of the first sheet 42, the side surface of the spacer 424, and the lower surface of the second sheet 44 (the lower surface of the inner sheet 46 described later) constitute the wall surface of the insertion path 422, and the space formed by these constitutes the insertion path 422. become.

  In addition, the 1st sheet | seat 42 and the spacer 424 may be comprised integrally, and you may comprise separately. For example, when the first sheet 42 and the spacer 424 are integrally formed of paper, the spacers 424 may be formed by bending both sides of the first sheet 42. Specifically, when the first sheet 42 and the spacer 424 are made of paper, both sides of the first sheet 42 may be bent to form the spacer 424, and the spacer 424 is separated and the first sheet 42 is separated. You may make it stick on both sides.

  Moreover, it is preferable that the wall surface of the insertion path 422 has water repellency. For example, the first sheet 42, the spacer 424, and the inner sheet 46 to be described later that constitute the wall surface constituting the insertion path 422 are each made of a water-repellent material (for example, water-repellent paper). Since the wall surface of the insertion path 422 has water repellency, the liquid droplets inserted into the insertion path 422 together with the collection unit 32 can be moved in the insertion path 422 without being absorbed by the wall surface of the insertion path 422. it can.

  Here, the case where the first sheet 42, the spacer 424, and the inner sheet 46 described later are made of a material having water repellency is exemplified, but a water repellent layer may be formed by a water repellent treatment. You may make it soak. Further, the entire insertion passage 422 may be surrounded by a material having water repellency. Further, at least one of the first sheet 42, the spacer 424, and the inner sheet 46 described later may have water repellency. For example, only the first sheet 42 and an inner sheet 46 described later may have water repellency. Further, each of the first sheet 42, the spacer 424, and the inner sheet 46 described later may partially have water repellency. For example, only the wall surface constituting the insertion path 422 may have water repellency.

  The second sheet 44 is formed by overlapping an inner sheet 46 and an outer sheet 48, and is held between the inner sheet 46 and the outer sheet 48 so that the test piece M is exposed to the insertion path 422. A through hole 462 is formed in a portion where the test piece M is disposed in the inner sheet 46, and the lower surface of the test piece M is exposed to the insertion passage 422 through the through hole 462.

  On the other hand, a through hole is formed in the outer sheet 48 at a portion where the test piece M is disposed, and this through hole constitutes the measurement window 482 described above. Since the measurement window 482 is formed on the side opposite to the insertion path 422 when viewed from the test piece M, the test piece M can be measured from the outside of the holding body 40 without pulling out the slide sheet 30 from the insertion path 422. If the test piece M is measured from the insertion path 422 side when viewed from the test piece M, the slide sheet 30 is obstructed, and the slide sheet 30 is pulled out from the insertion path 422 to measure the test piece M. Operation is also required. In the present embodiment, the operation can be simplified as compared with a case where an operation of pulling out the slide sheet 30 from the insertion path 422 is necessary to measure the test piece M.

  Note that the outer sheet 48 of the present embodiment is black. By making the outer sheet 48 black, light can be hardly reflected from the surface of the outer sheet 48 other than the measurement window 482. Therefore, when light is emitted from the light emitting unit 17 toward the test piece M exposed from the measurement window 482, it is possible to prevent the light receiving unit 18 from receiving reflected light from other than the test piece M that may cause measurement errors. be able to. The color of the outer sheet 48 is not limited to black, and may be any color that hardly reflects light.

  The surface of the collection part 32 of this embodiment has at least one recess 322 for collecting liquid. Specifically, as shown in FIG. 5 and FIG. 6, the sampling portion 32 of the present embodiment is formed into an uneven shape that repeats a mountain fold and a valley fold, for example, a bellows shape. 322 is formed. However, the shape of the recessed part 322 of this embodiment is not restricted to this. In this manner, by forming the recess 322 on the surface of the collection unit 32, the liquid in contact with the collection unit 32 can easily enter the recess 322 and be retained as a droplet. For this reason, the slide sheet 30 is slid with respect to the holding body 40, and the sampling part 32 is inserted only to the position where the test piece M is exposed to the insertion path 422, and the sampling part 32 is not pressed against the test piece M. It becomes easier for the test piece M to absorb the liquid droplets held by the collection unit 32. Therefore, since the operation of pressing the sampling part 32 against the test piece M is unnecessary, the operation can be simplified. Further, by making the collecting portion 32 uneven such as an accordion shape, a plurality of the concave portions 322 into which the liquid can enter is formed, so that it becomes easier to collect more liquid.

  At least the surface of the slide sheet 30 having the concave portion 322 of the collection part 32 has water repellency. According to this, the liquid that has come into contact with the collection unit 32 is not absorbed by the collection unit 32 and is easily moved to the recess 322, so that a larger amount of liquid can be held. Furthermore, small droplets are gathered together by the surface tension and become large droplets and are easily held. Thereby, the effect of making the test piece M easily absorb the liquid droplets held by the collection unit 32 can be enhanced.

  Note that a water-repellent layer may be formed on the surface of the sampling part 32 having the recess 322 by water-repellent treatment, or a water-repellent agent may be soaked. Further, not only the surface of the collection unit 32 having the recess 322 but the entire collection unit 32 or the entire slide sheet 30 including the collection unit 32 may have water repellency. For example, the entire collection unit 32 or the entire slide sheet 30 including the collection unit 32 may be made of a material having water repellency (for example, water-repellent paper).

  The first sheet 42 shown in FIG. 6 has a shorter depth (length in the X direction) as viewed from the collection unit 32 side of the slide sheet 30 than the second sheet 44, and the first sheet 42 from the collection unit 32 side of the slide sheet 30. As viewed, the leading end X1 of the first sheet 42 is configured to be in a position retracted from the leading end X2 of the second sheet 44.

  With this configuration, a portion (a portion from X2 to X1) that does not overlap the first sheet 42 can be provided on the leading end side of the second sheet 44. Thereby, in the slide sheet 30 inserted through the insertion passage 422, the portion extending from the tip of the first sheet 42 (the portion from X1 to the sampling portion 32 in FIG. 6) is away from the second sheet 44 ( It becomes easy to bend in the direction of the arrow in FIG. When the liquid is collected in the collection unit 32, the weight of the liquid is also added, so that it becomes easier to bend.

  Therefore, the collection unit 32 of the slide sheet 30 is inserted into the tip X1 of the first sheet 42 from an oblique angle, so that the liquid droplet held in the collection unit 32 is not repelled by the tip X2 of the second sheet 44. The first sheet 42 is easily pulled into the insertion path 422 from the tip X1. As a result, many liquid droplets held in the collection unit 32 are easily inserted into the insertion path 422. It should be noted that a crease may be put at a position around the tip X2 of the second sheet 44 of the slide sheet 30 so that the slide sheet 30 is easily bent in a direction away from the second sheet 44. .

  The operation when the liquid collected by the collection unit 32 is measured by the liquid component measurement cartridge 20 having such a configuration will be described. FIG. 7A is an explanatory diagram of the operation of the liquid component measurement cartridge 20 and shows a state before the slide sheet 30 is slid. FIG. 7B is an operation explanatory diagram following FIG. 7A, and shows a state in the middle of sliding the slide sheet 30. FIG. 7C is an operation explanatory view following FIG. 7B, and shows a state in which the slide sheet 30 is slid to the position where the sampling unit 32 faces the test piece M. 8A is a QA-QA sectional view in the state shown in FIG. 7B, and FIG. 8B is a QB-QB sectional view in the state shown in FIG. 7C.

  When the liquid N such as urine is applied to the collection portion 32 of the slide sheet 30, the liquid N enters and is collected in each of the plurality of recesses 322 as shown in FIG. 7A. In this state, when the slide sheet 30 is slid in the direction of the arrow, the slide sheet 30 slides in the holding body 40 as shown in FIG. 7B. Then, as shown in FIG. 7C, the slide sheet 30 is slid to a position where the collection unit 32 faces the test piece M.

  Then, the collection unit 32 moves from the oblique direction toward the insertion path 422 as shown by the arrow in FIG. 8A while holding the liquid N in the plurality of recesses 322, and is held by the collection unit 32 as shown in FIG. 8B. The liquid N is inserted into the insertion passage 422 together with the collection unit 32 and is contacted with the test piece M to be absorbed. At this time, since the collecting portion 32 has a concave and convex shape like a bellows, when the collecting portion 32 is inserted into the insertion passage 422, the liquid N droplets are recessed 322 as compared with the case where the collecting portion 32 is flat. Hard to spill. That is, when the liquid N held in the plurality of concave portions 322 of the collection unit 32 is inserted into the insertion passage 422, the liquid N moves while being pressed between the wall surface of the insertion passage 422 (the lower surface of the inner sheet 46) and the concave portion 322. . When the liquid N droplet enters the through-hole 462, since the pressing by the wall surface of the insertion path 422 (the lower surface of the inner sheet 46) is eliminated at once, the liquid M droplet is easily absorbed by the test piece M.

  8A, the height H ′ from the lowest part of the bellows-shaped valley fold to the highest part of the mountain fold is the height (gap) H of the insertion path 422. It is more effective to make it higher. That is, the bellows-like height H ′ of the sampling part 32 and the height of the insertion path 422 are configured such that the bellows-like height H ′ of the sampling part 32 is higher than the height H of the insertion path 422. Compared with the case where H is substantially the same, the depth of the concave portion 322 of the bellows-like valley fold portion can be increased before the sampling portion 32 is inserted into the insertion passage 422. The liquid N is easily held. 8B, when the sampling portion 32 is inserted into the insertion passage 422, the bellows-like collection portion 32 extends, and the mountain fold portion and the valley fold portion expand in the X direction, while the upper and lower portions of the insertion passage 422 are extended. The insertion path 422 can be closed by contacting the wall. Accordingly, the liquid N held in the concave portion 322 of the bellows-like valley fold portion of the collection unit 32 can be moved to a position facing the test piece M without leaking.

  In the present embodiment, the case where the bellows-like height H ′ of the sampling part 32 is made higher than the height H of the insertion path 422 is exemplified. The height H ′ may be the same as the height H of the insertion path 422, or may be lower than the height H of the insertion path 422. Even in this case, by sliding the slide sheet 30 to the positive side in the X direction, the liquid collected in the recess 322 of the collection unit 32 can be moved while being inserted into the insertion path 422 as a droplet. Therefore, compared with the case where the collection part 32 is flat, it can make it easy to make the test piece M absorb a liquid.

  In the present embodiment, the height of the slide sheet 30 (thickness in the Z direction) is made lower than the height (gap) H of the insertion path 422, and the Z direction is interposed between the slide sheet 30 and the insertion path 422. Although the gap is generated, the size of the gap in the Z direction can be adjusted by the height of the slide sheet 30 and the height H of the insertion path 422, and the gap can be hardly generated. If the gap in the Z direction is small, the bellows-like portion of the sampling part 32 is easily crushed in the Z direction, but the insertion part 422 is also inserted in the Z direction when the sampling part 32 is inserted into the insertion path 422. It becomes easy to spread. Therefore, it can also be said that the liquid collected in the bellows-like recess 322 of the collection part 32 is moved without leaking by the insertion passage 422 spreading in the Z direction in this way.

  As described above in detail, according to the present embodiment, the sliding sheet 30 is slid with respect to the holding body 40, and the sampling part 32 is inserted to the position where the test piece M is exposed to the insertion path 422. Even if the part 32 is not pressed against the test piece M, the liquid drop held by the collecting part 32 can be easily absorbed by the test piece M. Therefore, since the operation of pressing the sampling part 32 against the test piece M is unnecessary, the operation can be simplified. Thus, according to the present embodiment, the collected liquid can be easily absorbed by the test piece while simplifying the operation. In this embodiment, the case of measuring urine components is taken as an example, but it is also possible to measure components in a liquid (specimen) other than urine by the liquid component measuring device 10 and the liquid component measuring cartridge 20. It is.

  As shown in FIG. 3, the slide sheet 30 according to the present embodiment includes a wide restricting portion 34 and a crease as a restricting portion that restricts the slide sheet 30 from being removed from the holding body 40 toward the sampling portion 32. However, the present invention is not limited to this, and only one of the restriction part 34 and the restriction part 36 may be provided. For example, FIG. 9 shows a specific example in which only the restriction unit 34 is provided without providing the restriction unit 36. In the configuration of FIG. 9, without providing the restricting portion 36 in the slide sheet 30, the end portion on the negative side in the X direction of the restricting portion 34 (the end portion of the portion wider than the portion inserted through the holding body 40), It is extended to the position of the restricting portion 36 in FIG. According to the configuration of FIG. 9, it is possible to restrict the slide sheet 30 from being pulled out from the holding body 40 toward the sampling section 32 only by the collecting unit 32, and the slide sheet 30 is in the positive direction of the X direction with respect to the holding body 40. Even if it is displaced, it can be easily returned to a predetermined position.

  Further, in the present embodiment, the shape of the concave portion 322 in the sampling portion 32 of the slide sheet 30 is not limited to a line-shaped groove, and may be a circular or elliptical groove, a substantially hemispherical groove, A semi-elliptical sphere may be sufficient. Here, the specific example at the time of making the shape of the recessed part 322 of the extraction | collection part 32 into a substantially hemispherical groove | channel is shown in FIG.10 and FIG.11. 10 and 11 are diagrams for explaining another modified example of the slide sheet, and FIG. 10 is an enlarged perspective view of a portion of the collection unit 32 of the slide sheet 30 according to another modified example. 11 is a cross-sectional view taken along the line XI-XI of the slide sheet of FIG. As shown in FIGS. 10 and 11, a plurality of concave portions 322 formed of spherical grooves are formed on the surface of the sampling portion 32 in another modification. For example, each recess 322 can be formed by pressing a sphere against the surface of the slide sheet 30. Even with such a configuration, the surface of the collection unit 32 can be made uneven.

  According to the slide sheet 30 shown in FIGS. 10 and 11, since the concave portion 322 of the collecting unit 32 is configured by a substantially hemispherical groove, a liquid droplet is further dropped compared with the case where the concave portion 322 is configured by a line-shaped groove. It is easy to collect in the state of. In addition, by sliding the slide sheet 30 to the positive side in the X direction, the liquid can be inserted into the holding body 40 as a droplet, so that the liquid can be easily absorbed by the test piece M.
