Description

[Technical field]

[0001] The present invention relates to a storage box. [Background technology]

[0002] An automated analyzer is a device that automatically performs qualitative or quantitative analysis of specific components contained in samples such as blood and urine. In an automated analyzer, liquids such as samples, reagents, and reaction solutions formed by reacting samples with reagents are aspirated and discharged through a nozzle. The nozzle has a small outer diameter compared to its length, is easily bent, and is a component that is vulnerable to impacts, so it is necessary to prevent it from being affected by impacts.

[0003] Patent document 1 discloses that in order to protect the shock-sensitive ferrite antenna from the effects of external shocks, the ferrite antenna is stored in a storage recess of a case via an elastic cap-shaped antenna frame attached to both ends of the ferrite antenna.

[0004] [Patent Document 1] JP 2006-238169 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the cap-shaped antenna frame disclosed in Patent Document 1 is insufficient to protect the tip of the nozzle. In other words, even if a cap-shaped antenna frame is attached to the tip of the nozzle, the cap-shaped antenna frame may slip along the outer circumferential surface of the nozzle when the storage box containing the nozzle is transported, and the inner wall may come into contact with the tip of the nozzle, causing damage.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a storage box that prevents rod-shaped members, such as nozzles used in automatic analyzers, from being damaged during transportation. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides a storage box for storing rod-shaped members used in an automatic analysis device, comprising a base on which a groove-shaped storage section on which the rod-shaped members are placed, and a lid that is placed over the base, wherein the storage section has a step on which a radially protruding protrusion provided at the base of the rod-shaped members is hooked, and a space between the tip of the rod-shaped members and an inner wall. Effect of the Invention

[0008] According to the present invention, it is possible to provide a storage box that prevents damage to rod-shaped members such as nozzles used in automatic analyzers during transportation. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A preferred embodiment of the storage box according to the present invention will be described below with reference to the attached drawings. The storage box stores rod-shaped members used in an automatic analyzer, so the automatic analyzer will be described first. An automatic analyzer is a device that analyzes samples using a reaction liquid obtained by reacting a sample, such as blood or urine, with a reagent.

[0011] An example of the overall configuration of an automatic analyzer will be described with reference to Figure 1. The automatic analyzer includes a specimen transport unit 102, a reagent disk 104, a specimen dispensing unit 105, a reagent dispensing unit 106, a reagent stirring unit 119, a reaction disk (incubator) 107, a reaction vessel transport unit 109, a pre-processing unit 114, a measurement unit 108, and a control unit 113. Each unit will be described below. Note that the vertical direction is the Z direction, and the horizontal plane is the XY plane.

[0012] The sample transport unit 102 transports the sample container 101 containing a sample such as blood or urine to a sample suction position 110. The reagent disk 104 stores the reagent container 103 containing the reagent used in the analysis at a predetermined temperature range.

[0013] The specimen dispensing unit 105 dispenses specimen from the specimen container 101 transported to the specimen suction position 110 to a reaction container arranged on a reaction disk 107. A specimen dispensing nozzle, which will be described later, is attached to the specimen dispensing unit 105. The reaction container into which the specimen is dispensed and the dispensing tip that is attached to the tip of the specimen dispensing nozzle when dispensing the specimen are stored in a consumables storage unit 111 and are transported to a predetermined position by a consumables transport unit 112.

[0014] The reagent dispensing unit 106 dispenses a reagent from the reagent container 103 stored on the reagent disk 104 to a reaction container arranged on the reaction disk 107 to which a sample has been dispensed. A reagent dispensing nozzle, which will be described later, is attached to the reagent dispensing unit 106. Prior to dispensing the reagent, the reagent containing magnetic particles in the reagent container 103 is stirred by the reagent stirring unit 119.

[0015] The reaction disk 107 keeps the reaction vessel into which the specimen and the reagent are dispensed within a predetermined temperature range, thereby promoting the reaction between the specimen and the reagent and generating a reaction liquid. The reaction vessel transport unit 109 transports the reaction vessel containing the reaction liquid from the reaction disk 107 to the reaction liquid dispensing position 117 via the pretreatment position 115 and the mixing position 116. At the pretreatment position 115, the pretreatment unit 114 sucks up unnecessary liquid and discharges a buffer solution as pretreatment of the reaction liquid contained in the reaction vessel. The pretreatment unit 114 is equipped with an unnecessary liquid suction nozzle and a buffer solution discharge nozzle, which will be described later. Next, the reaction liquid is stirred at the mixing position 116. Then, at the reaction liquid dispensing position 117, the reaction liquid is supplied from the reaction vessel to the measurement unit 108 by the reaction liquid suction nozzle, which will be described later.

[0016] The measurement unit 108 measures the physical properties of the supplied reaction liquid, such as the amount of luminescence, the amount of scattered light, the amount of transmitted light, the current value, the voltage value, and the like. Note that the physical properties measured are not limited to these. The measurement unit 108 may also receive a reaction vessel from the reaction vessel transport unit 109 and measure the physical properties of the reaction liquid while it is still contained in the reaction vessel. The reaction vessel containing the reaction liquid whose physical properties have been measured by the measurement unit 108 is transported to the disposal hole 118 by the reaction vessel transport unit 109 and disposed of. Note that the reaction vessel after measurement may be washed and then reused.

[0017] The control unit 113 is a device that controls each unit included in the automatic analyzer and executes processing related to the measurement results, and is configured, for example, by a so-called computer.

[0018] 2A to 2E, various nozzles, which are rod-shaped members used in an automatic analyzer, will be described. The specimen dispensing nozzle 210 illustrated in FIG. 2A has a nozzle body 211, a protective part 212, and a bent metal plate 213. The nozzle body 211 is a cylindrical thin tube, and a specimen is aspirated and discharged from the tip. Although the nozzle body 211 is made of, for example, stainless steel, it is easily bent because the outer diameter is small compared to the length, and when the tip is crushed, it causes problems in aspirating and discharging the specimen. The protective part 212 is a cylindrical member that covers the outer periphery of the nozzle body 211 to protect the nozzle body 211, particularly to suppress bending of the nozzle body 211, and is made of, for example, stainless steel. Note that the tip of the nozzle body 211 is not covered by the protective part 212 because a dispensing tip is attached to it. The bent metal plate 213 is provided at one end of the specimen dispensing nozzle 210, that is, on the opposite side to the end where the dispensing tip is attached. Hereinafter, the end where the bent metal plate 213 is provided will be referred to as the base, and will be distinguished from the tip, which is the end where the sample is aspirated and discharged. The other nozzles also have two ends that are distinguished as the tip and the base. The bent metal plate 213 functions as a detection plate for detecting that the sample dispensing nozzle 210 is connected to the sample dispensing unit 105, and is provided protruding in the radial direction of the sample dispensing nozzle 210.

[0019] The reagent dispensing nozzle 220 illustrated in FIG. 2B has a nozzle body 221, a protective part 222, and a bent metal plate 223. The nozzle body 221 is a cylindrical thin tube, and a reagent is sucked in and discharged from the tip. The nozzle body 221 is easily bent like the nozzle body 211, and when the tip is crushed, it causes problems in sucking in and discharging the reagent. The protective part 222 covers the outer periphery of the nozzle body 221 to protect it like the protective part 212. Note that the tip of the nozzle body 221 is inserted into the reagent container 103, and is not covered by the protective part 222. The bent metal plate 223 is provided on the base side of the reagent dispensing nozzle 220. The bent metal plate 223 functions as a detection plate like the bent metal plate 213, and is provided protruding in the radial direction of the reagent dispensing nozzle 220.

[0020] The unnecessary liquid suction nozzle 230 illustrated in FIG. 2C has a nozzle body 231, a protective part 232, and a flange part 233. The nozzle body 231 is a cylindrical thin tube, and unnecessary liquid in the reaction liquid is sucked from the tip. The nozzle body 231 is easily bent like the nozzle body 211, and if the tip is crushed, it will hinder the suction of unnecessary liquid. The protective part 232 covers the outer periphery of the nozzle body 231 to protect it like the protective part 212. Note that the tip of the nozzle body 231 is inserted into the reaction vessel, so it is not covered by the protective part 232. The flange part 233 is provided on the base side of the unnecessary liquid suction nozzle 230. The flange part 233 has a shape illustrated in FIG. 2C so that a tube of the pre-treatment unit 114 can be attached, and is provided protruding in the radial direction of the unnecessary liquid suction nozzle 230.

[0021] The buffer solution discharge nozzle 240 illustrated in FIG. 2D has a nozzle body 241, a protective part 242, and a flange part 243. The nozzle body 241 is a cylindrical thin tube, and the buffer solution is discharged from the tip. The nozzle body 241 is easily bent like the nozzle body 211, and especially if the tip is crushed, it causes a problem in discharging the buffer solution. The protective part 242 covers the outer periphery of the nozzle body 241 to protect it like the protective part 212. Note that the tip of the nozzle body 241 is inserted into the reaction vessel, and is not covered by the protective part 242. The flange part 243 is provided on the base side of the buffer solution discharge nozzle 240. Like the flange part 233, the flange part 243 is provided to protrude in the radial direction of the buffer solution discharge nozzle 240 since a tube of the pretreatment part 114 is attached to the flange part 243.

[0022] The reaction liquid suction nozzle 250 illustrated in FIG. 2E has a nozzle body 251, a protective part 252, and a flange part 253. The nozzle body 251 is a cylindrical thin tube, and the reaction liquid that has been pretreated, such as sucking unnecessary liquid and discharging a buffer solution, is sucked from the tip. The nozzle body 251 is easily bent like the nozzle body 211, and if the tip is crushed, it will hinder the suction of the reaction liquid after pretreatment. The protective part 252 covers the outer periphery of the nozzle body 251 to protect it, like the protective part 212. Note that the tip of the nozzle body 251 is inserted into a reaction vessel, so it is not covered by the protective part 252. The flange part 253 is provided on the base side of the reaction liquid suction nozzle 250. The flange part 253 is provided so as to protrude in the radial direction of the reaction liquid suction nozzle 250, since a tube is attached to the flange part 253 like the flange part 233.

[0023] The nozzles, which are rod-shaped members used in the automatic analyzer described above, are stored in a storage box and are transported together with the delivered automatic analyzer. During transportation, it is important to prevent damage to the nozzles, especially damage to the tips of the nozzles due to contact with each other.

[0024] 3, a storage box 300 in which various nozzles, which are rod-shaped members, are stored will be described. Storage box 300 is composed of base 301 and lid 302 connected by hinge 303, and is molded as a single unit, for example, by vacuum molding. By molding as a single unit, storage box 300 becomes a member with a uniform thickness, that is, a member in which the back surface of a protruding surface is recessed, making mass production easy. In addition, storage box 300 is made of a material that is suppressed from deforming due to temperature changes during transportation, for example, a resin material PS (Poly Styrene) with a heat-resistant temperature of 70 to 90°C.

[0025] The base 301 is provided with a groove-shaped storage section on which various nozzles, which are rod-shaped members, are placed. The storage box 300 is preferably used for transporting a large number of rod-shaped members, and the base 301 illustrated in Fig. 3 is provided with first to seventh storage sections 310 to 370. Also, in order to prevent the storage box 300 from wobbling when placed on a horizontal surface, the edge on the bottom side of the base 301 may be structured to protrude horizontally.

[0026] The lid 302 is placed on the base 301 while bending the hinge 303, and has a first protrusion 311 to a seventh protrusion 371 that fits into the first storage section 310 to the seventh storage section 370, respectively, when the lid 302 is placed on the base 301. The first protrusion 311 to the seventh protrusion 371 come into contact with and press the various nozzles placed in the first storage section 310 to the seventh storage section 370, respectively. If the lid 302 bends, the positions of the first protrusion 311 to the seventh protrusion 371 may be shifted. Therefore, in order to improve the rigidity of the lid 302, a rib 306 may be provided to connect the long sides of the lid 302. The number, position, and shape of the rib 306 are not limited to the example shown in FIG. 3.

[0027] Furthermore, the lid 302 may have a fitting portion 304 on one of its four sides that faces the side to which the hinge 303 is connected, and the base 301 may have a fitted portion 305 at a position opposite to the fitting portion 304. By providing the fitting portion 304 on the lid 302 and the fitted portion 305 on the base 301, the two can be easily locked together by placing the lid 302 on the base 301. In order to maintain an appropriate lock strength and make it easy for a user to open the lid 302 with both hands, it is preferable that the sets of the fitting portion 304 and the fitted portion 305 are provided at two corners as shown in FIG.

[0028] 4 shows a state in which various nozzles, which are rod-shaped members, are placed in the first storage section 310 to the seventh storage section 370. A sample dispensing nozzle 210 is placed in the first storage section 310, a reagent dispensing nozzle 220 is placed in the second storage section 320, an unwanted liquid suction nozzle 230 is placed in the third storage section 330, a buffer solution discharge nozzle 240 is placed in the fourth storage section 340, and a reaction liquid suction nozzle 250 is placed in the fifth storage section 350. In addition, a stirring paddle 260 used for stirring the reagent is placed in the sixth storage section 360, and a supplies bag 270 containing supplies 271 is placed in the seventh storage section 370.

[0029] 5 shows a state in which lid 302 is placed on base 301 and lid 302 and base 301 are locked together by a pair of fitting portion 304 and fitted portion 305. When lid 302 and base 301 are locked together, first protrusion 311 to seventh protrusion 371 approach each other until the gap between them and rod-shaped members such as various nozzles placed in first storage portion 310 to seventh storage portion 370 becomes less than the outer diameter of the rod-shaped members, thereby suppressing movement of the rod-shaped members due to vibration during transportation.

[0030] The first storage section 310 to the fifth storage section 350 will be described with reference to Figures 6A to 6E. The first storage section 310 illustrated in Figure 6A, which is a cross-sectional view taken along the line AA in Figure 5, stores the sample dispensing nozzle 210, and is divided into a first region 511 to a fifth region 515 from the base side along the longitudinal direction of the sample dispensing nozzle 210. The first region 511 is a region in which the bent metal plate 213 is stored, and is a groove that is deeper than the adjacent second region 512. The second region 512 is a region in which the sample dispensing nozzle 210 comes into contact with the bottom surface of the first storage section 310, and the movement of the sample dispensing nozzle 210 is suppressed by the first protrusion 311, and is a groove that is shallower than the adjacent first region 511 and third region 513. The third region 513 is a region having a space in which a user can insert his or her fingers to hold the sample dispensing nozzle 210, and is a groove that is deeper than the adjacent second region 512 and fourth region 514. The space for the finger to fit in is provided in a direction perpendicular to the longitudinal direction of the sample dispensing nozzle 210. The fourth region 514 is a region where the sample dispensing nozzle 210 comes into contact with the bottom surface of the first storage section 310 and movement is suppressed by the first protrusion 311, and is a shallower groove than the adjacent third region 513 and fifth region 515. The fifth region 515 is a region where a space is provided between the tip of the sample dispensing nozzle 210 and the inner wall, and is a deeper groove than the adjacent fourth region 514. The third region 513 and the fourth region 514 may be omitted.

[0031] With this configuration, the bent metal plate 213 protruding in the radial direction is caught on the step provided between the first region 511 and the second region 512, thereby maintaining a space between the tip of the specimen dispensing nozzle 210 and the inner wall of the first storage section 310. In other words, since the tip of the specimen dispensing nozzle 210 does not need to come into contact with the inner wall of the first storage section 310, damage to the specimen dispensing nozzle 210 during transportation can be prevented.

[0032] Since the sample dispensing nozzle 210, whose movement is restricted by the first protrusion 311, remains in contact with the bottom surface of the first storage section 310 in the second region 512, it is possible to prevent the bent metal sheet 213 from coming off the step between the first region 511 and the second region 512. In addition, it is preferable that the step between the first region 511 and the second region 512 is larger than the height to which the bent metal sheet 213 protrudes in the radial direction.

[0033] The second storage section 320 illustrated in FIG. 6B, which is a cross-sectional view taken along the line BB in FIG. 5, stores the reagent dispensing nozzle 220, and is divided into a first region 521 to a fifth region 525, similar to the first storage section 310. The first region 521 is a region in which the bent metal plate 223 is stored, and is a groove that is deeper than the adjacent second region 522. The second region 522 is a region in which the reagent dispensing nozzle 220 contacts the bottom surface of the second storage section 320, and is a groove that is shallower than the adjacent first region 521 and third region 523. The third region 523 is a region having a space in which a user can insert his or her fingers to grip the reagent dispensing nozzle 220, and is a groove that is deeper than the adjacent second region 522 and fourth region 524. The fourth region 524 is a region in which the reagent dispensing nozzle 220 contacts the bottom surface of the second storage section 320, and movement is suppressed by the second protrusion 321, and is a groove that is shallower than the adjacent third region 523 and fifth region 525. The fifth region 525 is a region where a space is provided between the tip of the reagent dispensing nozzle 220 and the inner wall, and is a groove that is deeper than the adjacent fourth region 524.

[0034] With this configuration, similar to the first storage section 310, the bent metal sheet 223 is hooked onto the step between the first area 521 and the second area 522, thereby preventing the tip of the reagent dispensing nozzle 220 from coming into contact with the inner wall of the second storage section 320, thereby preventing damage to the reagent dispensing nozzle 220 during transport.

[0035] The third storage section 330 illustrated in FIG. 6C, which is a cross-sectional view taken along the line CC in FIG. 5, stores the unnecessary liquid suction nozzle 230, and is divided into a first region 531 to a fifth region 535, similar to the first storage section 310. The first region 531 is a region in which the flange portion 233 is stored, and is a groove deeper than the adjacent second region 532. The second region 532 is a region in which the unnecessary liquid suction nozzle 230 contacts the bottom surface of the third storage section 330, and is a groove shallower than the adjacent first region 531 and third region 533. The third region 533 is a region having a space in which a user can insert his or her fingers to pinch the unnecessary liquid suction nozzle 230, and is a groove deeper than the adjacent second region 532 and fourth region 534. The fourth region 534 is a region in which the unnecessary liquid suction nozzle 230 contacts the bottom surface of the third storage section 330, and movement is suppressed by the third protrusion 331, and is a groove shallower than the adjacent third region 533 and fifth region 535. The fifth region 535 is a region where a space is provided between the tip of the unnecessary liquid suction nozzle 230 and the inner wall, and is a groove that is deeper than the adjacent fourth region 534 .

[0036] With this configuration, the radially protruding flange portion 233 hooks onto the step between the first region 531 and the second region 532, eliminating the need for the tip of the unnecessary liquid suction nozzle 230 to come into contact with the inner wall of the third storage section 330, thereby preventing damage to the unnecessary liquid suction nozzle 230 during transportation.

[0037] The fourth storage section 340 illustrated in FIG. 6D, which is a DD cross-sectional view of FIG. 5, stores the buffer discharge nozzle 240, and is divided into a first region 541 to a fifth region 545, similar to the first storage section 310. The first region 541 is a region in which the flange portion 243 is stored, and is a groove deeper than the adjacent second region 542. The second region 542 is a region in which the buffer discharge nozzle 240 comes into contact with the bottom surface of the fourth storage section 340, and is a groove shallower than the adjacent first region 541 and third region 543. The third region 543 is a region having a space in which a user can insert his / her fingers to grip the buffer discharge nozzle 240, and is a groove deeper than the adjacent second region 542 and fourth region 544. The fourth region 544 is a region in which the buffer discharge nozzle 240 comes into contact with the bottom surface of the fourth storage section 340, and movement is restricted by the fourth protrusion 341, and is a groove shallower than the adjacent third region 543 and fifth region 545. The fifth region 545 is a region where a space is provided between the tip of the buffer solution discharge nozzle 240 and the inner wall, and is a groove that is deeper than the adjacent fourth region 544 .

[0038] With this configuration, similarly to the third storage section 330, the flange portion 243 is caught on the step between the first region 541 and the second region 542, so that the tip of the buffer solution discharge nozzle 240 does not come into contact with the inner wall of the fourth storage section 340, and damage to the buffer solution discharge nozzle 240 during transportation can be prevented.

[0039] The fifth storage section 350 illustrated in FIG. 6E, which is an E-E cross-sectional view of FIG. 5, stores the reaction liquid aspirating nozzle 250, and is divided into a first region 551 to a fifth region 555, similar to the first storage section 310. The first region 551 is a region in which the flange portion 253 is stored, and is a groove deeper than the adjacent second region 552. The second region 552 is a region in which the reaction liquid aspirating nozzle 250 contacts the bottom surface of the fifth storage section 350, and is a groove shallower than the adjacent first region 551 and third region 553. The third region 553 is a region having a space in which a user can insert his / her fingers to pinch the reaction liquid aspirating nozzle 250, and is a groove deeper than the adjacent second region 552 and fourth region 554. The fourth region 554 is a region in which the reaction liquid aspirating nozzle 250 contacts the bottom surface of the fifth storage section 350, and movement is suppressed by the fifth protrusion 351, and is a groove shallower than the adjacent third region 553 and fifth region 555. The fifth region 555 is a region where a space is provided between the tip of the reaction liquid suction nozzle 250 and the inner wall, and is a groove that is deeper than the adjacent fourth region 554.

[0040] With this configuration, similar to the third storage section 330, the flange portion 253 hooks onto the step between the first region 551 and the second region 552, preventing the tip of the reaction liquid suction nozzle 250 from coming into contact with the inner wall of the fifth storage section 350, thereby preventing damage to the reaction liquid suction nozzle 250 during transport.

[0041] The positional relationship in the height direction between the storage section provided in base 301 and the protrusion provided in lid 302 will be described with reference to Fig. 7. Fig. 7 is an FF cross-sectional view of Fig. 5, and the positional relationship will be described using third storage section 330 in which unnecessary liquid suction nozzle 230 is stored as an example of the storage section, and third protrusion 331 housed in third storage section 330 as an example of the protrusion.

[0042] For manufacturing convenience, a flat surface 330A is formed on the side of the groove of the third storage section 330. The third protrusion 331 has a tip surface 331A that contacts the unnecessary liquid suction nozzle 230. When the distance between the flat surface 330A and the tip surface 331A is h and the lift amount of the lid 302 is d, the third storage section 330 and the third protrusion 331 are configured so that h>d. With this configuration, it is possible to avoid a gap between the third storage section 330 and the third protrusion 331 that is large enough for the unnecessary liquid suction nozzle 230 to pass through, that is, a gap larger than the outer diameter of the unnecessary liquid suction nozzle 230. In addition, the gap between the third protrusion 331 and the unnecessary liquid suction nozzle 230 is smaller than the outer diameter of the unnecessary liquid suction nozzle 230. As a result, the third protrusion 331 can prevent the unnecessary liquid suction nozzle 230 from moving.

[0043] The embodiments of the present invention have been described above. The present invention is not limited to the above embodiments, and the components may be modified without departing from the gist of the invention.
