Description

  The present invention relates to a support adjustment member, a container storage rack, and an analyzer.

  2. Description of the Related Art Conventionally, there has been known an analyzer (biochemical analyzer) for reacting a sample (for example, blood or urine) with a reagent to measure various components such as sugar, cholesterol, protein, and enzyme. When performing such a measurement, a reagent corresponding to the content of the measurement is required. That is, the analyzer accommodates reagent containers each containing a plurality of types of reagents individually in a reagent storage (reagent station) of the analyzer. The analyzer performs a suction operation of selecting a predetermined reagent from among a plurality of types of reagents, moving a reagent container containing the selected reagent to a suction dispenser, and sucking an appropriate amount. By the way, depending on the type of test or measurement, the amount of the reagent used at one time may be different, or the usable period after opening (after starting use) may be different. That is, the consumption rate differs for each reagent. Therefore, the size (capacity) of the reagent container may vary depending on the type of the reagent. Therefore, there is a concept that a plurality of types of reagent containers having different sizes are mixed and accommodated in a single rack. In this case, since a small reagent container is held in a large storage space, it is necessary to support the reagent container so as not to cause a displacement or the like on the rack. For example, Patent Literature 1 proposes a reagent container adapter that can support a plurality of types of reagent containers, that is, reagent containers having different sizes in a reagent storage (for example, see Patent Literature 1). Has proposed a support adjustment member for supporting a plurality of containers in a rack body, that is, for supporting containers of different sizes (for example, see Patent Document 2).

Patent No. 4754994 JP-A-2017-090356

  However, the reagent container adapter of Patent Document 1 described above uses a dedicated partition member for each size of the reagent container in order to adapt to the size of the reagent container different from the size of the accommodation room of the reagent container adapter. I was The partition member is configured to be supported by a guide rail formed on a side wall of the storage chamber. Therefore, in order to stably attach the partition member to the reagent container without causing displacement or the like, it is necessary to increase the thickness of the side wall on which the guide rail is formed. That is, the space required to form one accommodation room has been increased. As a result, there is a problem that the number of storage chambers that can be formed on a limited rack space decreases, and the storage capacity (the number of storages) of the reagent containers decreases. Further, in the support adjustment member of Patent Document 2 described above, the support adjustment member is joined to different positions in the rack main body in order to adapt to different container sizes, and the number of parts to be joined of the rack main body is Therefore, a larger number of joints are required than the joints of the support adjustment members, so that the joints of the support adjustment members can be selectively joined to different joints. As a result, there is a problem that the rack body needs to form a large number of joints. Further, in the support adjusting member of Patent Document 2 described above, the reagent container is inclined at a specific angle by the inclined side surface of the support adjusting member. As a result, there is a problem that reagent containers of different sizes cannot be inclined at the same specific angle due to a difference in shape of a portion leaning on the side surface of the reagent container.

  Therefore, one of the objects of the present invention is to provide a container storage rack and a support adjustment member for the container that can suppress a decrease in the container capacity even when containers of different sizes can be stored.

The support adjustment member for attaching to the rack body accommodating the first container or the second container having a different size from the first container of the embodiment has a first support side portion and a second support side portion facing each other. In the first joining state in which the supporting portion is joined to the bottom wall portion of the rack body, the first support side faces the supporting wall portion of the rack body, and the first container accommodated in the rack body is It is positioned in contact with the first support side and the support wall. In a second joining state different from the first joining state in which the support is joined to the bottom wall, the second support side faces the support wall, and the second container housed in the rack body is the second support side. And the support wall is positioned in contact with the support wall.
The container storage rack of the embodiment includes the support adjustment member and the rack body.
The container storage rack and the information processing device according to the embodiment are attached to an analyzer.

  According to the embodiment, as an example, since the support adjustment member for attaching the containers having different sizes to the rack body is attached to the bottom wall portion that hardly affects the accommodation capacity of the container, the decrease in the accommodation capacity of the container is reduced. Can be suppressed. In addition, by attaching the support adjustment member at the bottom wall, the posture of the support adjustment member in the storage section can be easily stabilized, and the container can be firmly positioned and supported in the storage section. Furthermore, the support adjustment member is adapted to accommodate containers of different sizes by changing its own orientation, so that the number of parts to be joined does not need to be greater than the number of joints of the support adjustment member. The complexity of the structure of the main body can be reduced (simplified).

  The reagent storage 12 has two rotation support portions 33A and 33B that rotate around a rotation center axis Ax2 (center of rotation). The rotation support portions 33A and 33B are configured to be rotatable separately. A drive mechanism (not shown) that rotationally drives the rotation support portions 33A and 33B includes, for example, a rotation source such as a motor and a rotation transmission mechanism such as a gear, a belt, and a pulley. The drive source of the drive mechanism may be shared by the two rotation support portions 33A and 33B, or may be provided corresponding to each of the rotation support portions 33A and 33B.

  The rotation support portion 33A supports a plurality of reagent containers 34 (for example, small containers 34a shown in FIG. 7) arranged in a ring around the rotation center axis Ax2. The rotation support portion 33B supports a plurality of reagent containers 34 (for example, a large container 34c shown in FIG. 7) arranged in a ring around the rotation center axis Ax2.

  A bar code for identifying the reagent contained in the reagent container 34 is provided on a radially outer surface of the reagent container 34 (a container label 50d added in FIG. 7). The barcode is read by the barcode reader 22 located radially outward of the rotation center axis Ax2 with respect to the rotation support portions 33A and 33B. The barcode reader 22 is an example of a reader.

  The reaction tank 13 has a rotating body 35 that is substantially circular in plan view. The rotating body 35 is supported by the housing 10 so as to be rotatable around a rotation center axis Ax3 along the vertical direction of the housing 10. The rotating body 35 is rotated around a rotation center axis Ax3 by a driving mechanism (not shown). The rotating body 35 is provided with a plurality of light-transmissive reaction vessels 36. The plurality of reaction vessels 36 are arranged around the rotation center axis Ax3, and rotate integrally with the rotating body 35. FIG. 5 shows a part of the plurality of reaction vessels 36. The reaction vessel 36 can be constituted by a cuvette, for example. A sample and a reagent are dispensed into the reaction container 36. The sample and the reagent react in the reaction vessel 36 to form a reaction solution. The inside of the reaction tank 13 is maintained at a temperature suitable for promoting the reaction between the sample and the reagent.

  The sample dispensing section 14 has a pipette 37 and a drive mechanism 38. The pipette 37 is rotated by a drive mechanism 38 between a position above the specimen storage 11 and a position above the reaction tank 13 around a rotation center axis Ax4 along the vertical direction of the housing 10. Further, the pipette 37 is moved along the vertical direction of the housing 10 by the driving mechanism 38. The pipette 37 is connected to a suction / discharge mechanism for performing a suction operation and a discharge operation of the sample. After aspirating the sample in the sample container 32 by the pipette 37 inserted in the sample container 32, the sample dispensing unit 14 inserts the pipette 37 into the reaction container 36, and from the pipette 37 into the reaction container 36. The sample can be ejected (dispensed).

  The reagent dispensing sections 15 and 16 have pipettes 39 and 40 and drive mechanisms 41 and 42, respectively. Pipettes 39 and 40 are driven by drive mechanisms 41 and 42, respectively, to rotate center axes Ax5 and Ax6 along the vertical direction of casing 10 between a position above reagent storage 12 and a position above reaction tank 13. Rotated around. Further, the pipettes 39 and 40 are moved along the vertical direction of the housing 10 by the driving mechanisms 41 and 42. Further, a suction and discharge mechanism for performing a suction operation and a discharge operation of the reagent is connected to the pipettes 39 and 40. After aspirating the reagent in the reagent container 34 by the pipettes 39 and 40 inserted in the reagent container 34, the reagent dispensing units 15 and 16 insert the pipettes 39 and 40 into the reaction container 36, respectively. The reagent can be discharged (dispensed) from the pipettes 39 and 40 into the reaction container 36.

  The measuring section 19 has a light source section 45 and a light receiving section (not shown). The light source section 45 is located outside the reaction tank 13 and emits a halogen light or the like to the reaction vessel 36. Irradiate light. The light receiving unit receives the light that has passed through the reaction vessel 36 and measures the intensity of the received light. The measuring unit 19 obtains the absorbance of the reaction solution in the reaction container 36 based on the light intensity measured by the light receiving unit. The light source unit 45 is configured to be able to switch the wavelength of the emitted light. Therefore, the measurement unit 19 can measure the absorbance of a plurality of types of light having different wavelengths.

  The stirring units 17 and 18 have a stirring member (not shown) that can be inserted into the reaction vessel 36. The stirring units 17 and 18 stir the sample and the reagent dispensed into the reaction container 36 by rotating a stirring member inserted into the reaction container 36.

  The cleaning unit 20 removes (discards) the reaction solution in the reaction vessel 36 and cleans the inside of the reaction vessel 36.

  The control unit 21 has, for example, a CPU, a ROM, and a RAM. The control unit 21 performs various calculations and controls of each unit of the sample processing apparatus 2.

  The sample processing apparatus 2 having the above configuration performs a measurement process. During the measurement process, the sample storage 11, the reagent storage 12, and the reaction tank 13 perform processing of the sample dispensing unit 14, the reagent dispensing units 15, 16, the stirring units 17, 18, the measuring unit 19, and the cleaning unit 20. It is rotated to the receiving position.

  As shown in FIG. 6, in the measurement process, the sample dispensing unit 14 dispenses a predetermined sample in the sample storage 11 into a predetermined reaction container 36 of the reaction tank 13 (S1). Next, the reagent dispensing unit 15 dispenses the first reagent in the reagent storage 12 according to the test item into the predetermined reaction container 36 (S2). Next, the stirring section 17 stirs the inside of the predetermined reaction vessel 36 (S3). Next, after a predetermined time has elapsed from the stirring, the measurement unit 19 measures the absorbance of the first reaction solution obtained by the reaction between the sample in the predetermined reaction container 36 and the first reagent (S4). . The measured absorbance is transmitted to the information processing device 3.

  Next, the reagent dispensing unit 16 dispenses the second reagent in the reagent storage 12 according to the test item to the predetermined reaction container 36 (S5). Next, the stirring section 18 stirs the inside of the predetermined reaction vessel 36 (S6). Next, after a lapse of a predetermined time from the stirring, the measurement unit 19 was obtained by the reaction between the first reaction solution (sample and first reagent) in the predetermined reaction vessel 36 and the second reagent. The absorbance of the second reaction solution is measured (S7). The measured absorbance is transmitted to the information processing device 3. Next, the washing unit 20 removes the second reaction solution in the predetermined reaction vessel 36 and cleans the inside of the reaction vessel 36 (S8). When two absorbances are obtained by such a measurement process, the information processing device 3 obtains the amounts of the components of the sample (for example, cholesterol level) based on the two absorbances. The processing in steps S1 to S8 is repeatedly performed for each sample and each test item. The pipettes 37, 39, and 40 are cleaned by a cleaning unit (not shown) at a predetermined timing.

  As described above, the reagent used in the biochemical analyzer 1 may vary depending on the type of measurement (content of analysis). In addition, the amount used at one time may vary depending on the type of measurement (contents of analysis). Further, the usable period after opening the reagent container 34 (after starting use) may be different. Therefore, the reagent may be contained in a reagent container 34 of a different size for each type so that an appropriate amount can be used within an appropriate period.

  FIG. 7 shows reagent containers 34 having different sizes. FIG. 7 shows three examples of a small container 34a (for example, a 20 ml bottle), a medium container 34b (for example, a 40 ml bottle), and a large container 34c (for example, a 70 ml bottle). The size of the reagent container 34 is not limited to this, and can be set as appropriate, and a larger container size may be used. The basic configuration of the small container 34a, the medium container 34b, and the large container 34c as the reagent container 34 is common. The reagent container 34 includes a container body 50a formed of resin, metal, glass, or the like, a container lid 50c for sealing the container opening 50b, and a container label 50d provided on the container body 50a. In FIG. 7, the large container 34c is illustrated with the container cover 50c removed and the container opening 50b exposed. The large container 34c is shown in a state where the container label 50d is not provided.

  As shown in FIG. 5, the reagent containers 34 are, for example, arranged in the cylindrical reagent storage 12 along the circumferential direction. In the case of FIG. 5, the large container 34c is accommodated and arranged in a container accommodating rack set on the radially outer rotation support portion 33B. The small container 34a is accommodated and arranged in a container accommodating rack set in the rotation support portion 33A on the radial inside. By arranging the reagent containers 34 in the circumferential direction in this manner, the desired reagent containers 34 housed in the reagent storage 12 that is driven to rotate about the rotation center axis Ax2 can be moved to the reagent dispensing unit 15 or the reagent dispensing unit 16. It can be quickly moved to a position. Further, many reagent containers 34 can be efficiently and densely accommodated in the limited space of the sample processing apparatus 2.

  The reagent containers 34 densely housed (arranged) in the circumferential direction as described above clearly have a width of the outer peripheral side surface 52a which is radially outward (outer peripheral side) when arranged in the circumferential direction, as clearly shown by the large container 34c. It is wider than the width of the inner peripheral side surface 52b on the side and is, for example, a substantially isosceles triangle when viewed from above. The container port 50b is formed, for example, on the outer peripheral side surface 52a side. The small container 34a and the medium container 34b can have a shape in which the inner peripheral side surface 52b side (tapered side) of the large container 34c is cut off. That is, the shape and size of the small container 34a and the medium container 34b on the outer peripheral side surface 52a side are the same as those of the large container 34c. Therefore, the position of the container opening 50b (container lid 50c) when the small containers 34a and the medium containers 34b are arranged in the circumferential direction is the same as the position of the container opening 50b when the large containers 34c are arranged in the circumferential direction. As a result, even when the small container 34a, the medium container 34b, and the large container 34c are accommodated in the container accommodating rack 54 (outer container accommodating rack 56) as shown in FIG. 8, the small container 34a, the medium container 34b, and the large container 34c The position of the container port 50b can be located on the same circumference. That is, the dispensing operation by the reagent dispensing units 15 and 16 can be easily performed on the reagent containers 34 of any size by the same operation.

  FIG. 8 shows an outer container housing rack 56 set on the rotary support 33B (the outer peripheral side of the reagent housing 12) as an example of the container housing rack 54 set (mounted, mounted) on the cylindrical reagent storage 12. Is shown in perspective view. The container storage rack 54 set so as to be annular as a whole is divided into a plurality in the circumferential direction. That is, as shown in FIG. 8, the outer container storage rack 56 has, for example, a substantially fan shape. As described above, by dividing the container housing rack 54 into a plurality of outer container housing racks 56, the handling of each outer container housing rack 56 becomes easy. For example, the reagent containers 34 having the same consumption rate can be combined in the same outer container housing rack 56, or the outer container housing rack 56 can be distinguished for each use start time of the reagent. The container storage rack 54 (outer container storage rack 56) can be formed of, for example, a resin material (for example, hard plastic) or a metal (for example, stainless steel or aluminum).

  8 includes a rack body 57 capable of accommodating a plurality of reagent containers 34 arranged in a circumferential direction, for example, and a support adjustment member 70 used for accommodating the small containers 34a and the medium containers 34b. (See FIG. 1). Details of the support adjustment member 70 will be described later. The rack main body 57 has a shape in which a plurality of storage portions 58 adapted to store the large containers 34c are arranged in the circumferential direction. The accommodation section 58 is a concave individual accommodation area defined by the partition wall section 56a, the support wall section 56b, the connection wall section 56c, and the bottom wall section 56d. The partition wall portion 56a is a wall interposed between the adjacent large containers 34c. The support wall 56b is a wall formed to connect the adjacent partition 56a on the outer peripheral side of the reagent storage 12, for example. Similarly, the connection wall portion 56c is a wall formed to connect the adjacent partition wall portions 56a on the inner peripheral side of the reagent storage 12, for example. The bottom wall portion 56d is a wall that forms a bottom surface that supports two adjacent partition walls 56a, a support wall portion 56b, and a connection wall portion 56c. It should be noted that the large container 34c having a size that fits the housing portion 58 may be referred to as a third container. Further, the reagent container 34 having a shorter length in the direction in which the support wall portion 56b and the connection wall portion 56c are opposed to each other than the third container, for example, the medium container 34b and the small container 34a may be referred to as a second container and a first container.

  Although not shown, a plurality of ribs extending upward from the bottom wall portion 56d are formed on the partition wall portion 56a, the support wall portion 56b, and the connection wall portion 56c which define (form) each of the housing portions 58. Have been. The plurality of ribs can support the container body 50a of the large container 34c to be accommodated with a small contact area (for example, in a state of substantially linear contact). As described above, by supporting the large container 34c in a line contact state, the resistance when the large container 34c is moved in and out of the housing portion 58 is reduced as compared with the case where the container main body 50a is supported by surface contact. Easy access (easy handling). Further, by supporting the container label 50d in a line contact state, the rubbing of the container label 50d applied to the large container 34c is reduced, and the damage of the container label 50d can be suppressed.

  A plurality of rack legs 56e are formed on the bottom wall 56d. The rack leg portion 56e holds the outer container housing rack 56 in a stable posture when the reagent container 34 such as the large container 34c is taken in and out of the outer container housing rack 56 and when the reagent container 34 is set at a predetermined position of the rotation support portion 33B. Be independent. Further, a handle portion 56f is formed on the rack body 57 so as to protrude upward. The handle portion 56f is formed with an opening through which a finger can be inserted, for example, when the outer container housing rack 56 is taken in and out of the reagent storage 12 or when transported to another place while holding the reagent container 34 such as the large container 34c. And so on. Although not shown, openings may be formed in walls constituting the rack body 57 such as the partition wall 56a, the support wall 56b, the connection wall 56c, and the bottom wall 56d. By forming the opening in the wall surface, the rigidity of the rack body 57 can be maintained, and it is possible to contribute to weight reduction, reduction of material costs, and the like. Further, a part of the reagent container 34 accommodated in the outer container housing rack 56 can be exposed from the outer container housing rack 56 via the opening (vent). By exposing a part of the reagent container 34, the efficiency of heating or cooling can be improved as compared with the case where there is no opening. Therefore, the temperature adjustment (temperature management) of the reagent container 34 can be easily performed through the opening. The outer container storage rack 56 configured as described above can mainly store the large container 34c containing the reagent that consumes a large amount.

  FIG. 9 is a perspective view of the inner container storage rack 60 as an example of the container storage rack 54 arranged inside (outer peripheral side) of the outer container storage rack 56 in the reagent storage 12. The inner container housing rack 60 is also divided into a plurality in the circumferential direction, and has, for example, a substantially fan shape, and when set in a state of being arranged in the circumferential direction, becomes the annular container housing rack 54 and the outer container housing rack 56. The same effect as described above can be obtained.

  The rack main body 61 of the inner container storage rack 60 shown in FIG. 9 can store, for example, small containers 34a arranged in a circumferential direction, for example. The rack main body 61 has, for example, a shape in which a plurality of storage portions 62 adapted to store the small containers 34a are arranged in the circumferential direction, similarly to the rack main body 57 of the outer container storage rack 56. In the case of the inner container storage rack 60, for example, an example is shown in which two rows (doubles) of the storage portions 62 are arranged in the radial direction. The accommodation section 62 is a concave individual accommodation area defined by the partition wall section 60a, the support wall section 60b, the connection wall section 60c, and the bottom wall section 60d. The partition part 60a is a wall interposed between the small containers 34a housed adjacent to each other. Further, the support wall portion 60b is a wall formed so as to connect the adjacent partition wall portion 60a on the outer peripheral side of the reagent storage 12, for example. Similarly, the connection wall portion 60c is a wall formed to connect the adjacent partition wall portion 60a on the inner peripheral side of the reagent storage 12, for example. The bottom wall portion 60d is a wall that forms a bottom surface that supports the two connected partition portions 60a, the support wall portion 60b, and the connection wall portion 60c.

  Although not shown, a plurality of ribs extending upward from the bottom wall portion 60d are formed and housed in the partition wall portion 60a, the support wall portion 60b, and the connection wall portion 60c which form each of the housing portions 62, for example. The container main body 50a of the small container 34a can be supported with a small contact area (for example, in a substantially line contact state). In other words, it functions in the same manner as the rib formed in the housing portion 58 of the outer container housing rack 56, and can obtain the same effect. A plurality of rack legs 60e are formed on the bottom wall 60d. The rack legs 60e function in the same manner as the rack legs 56e of the outer container housing rack 56, and can obtain the same effects. The rack main body 61 has a fixed hook portion 60f which engages with a drive mechanism (not shown) in the reagent storage 12 shown in FIG. 5 to attach the inner container housing rack 60 to the rotation support portion 33A. The fixed hook portion 60f also functions as a handle for carrying the inner container housing rack 60. In other words, the fixed hook portion 60f can be used when the inner container storage rack 60 is taken in and out of the reagent storage 12, or when the small container 34a is transported to another place while being stored. Although not shown, an opening may be formed in a wall constituting the rack main body 61. By forming the opening in the wall surface, the rigidity of the rack main body 61 can be maintained, and the weight of the inner container housing rack 60 can be reduced and the material cost can be reduced. Further, a part of the reagent container 34 housed in the inner container housing rack 60 can be exposed from the inner container housing rack 60 through the opening (vent). Therefore, the temperature adjustment (temperature management) of the reagent container 34 can be easily performed through the opening. Further, the temperature control (temperature management) of the small containers 34a accommodated in the inner container accommodation rack 60 can be easily performed through the openings. Although the inner container housing rack 60 shown in FIG. 9 shows an example in which the housing portion 62 is configured to house the small container 34a, the inner container housing rack 60 may include the housing portion 62 suitable for housing the medium-sized container 34b. In this case, the accommodating portions 62 can be configured, for example, in a line in the circumferential direction. Further, the outer peripheral side of the inner container storage rack 60 may be the storage part 62 of the medium-sized container 34b, and the inner peripheral side may be the storage part 62 of the small container 34a.

  FIG. 10 is a plan view showing a state where the outer container housing rack 56 and the inner container housing rack 60 are set (mounted) on the rotation support portions 33B and 33A (see FIG. 5) of the reagent storage 12. In the case of FIG. 10, five sets of outer container storage racks 56 are arranged in a substantially annular shape in the circumferential direction. Each outer container storage rack 56 stores ten large containers 34c. That is, the reagent storage 12 can store 50 large containers 34c using the outer container storage rack 56. Inside the outer container housing rack 56, five sets of inner container housing racks 60 are arranged in a substantially annular shape in the circumferential direction. Each inner container storage rack 60 stores five small containers 34a in the circumferential direction and two rows in the radial direction. That is, each of the inner container storage racks 60 stores ten small containers 34a. Therefore, in the case of the reagent storage 12, 50 small containers 34 a can be stored using the inner container storage rack 60. In FIG. 10, an unaccommodated area 63 in which the reagent container 34 is not accommodated is formed in a part of the outer container accommodating rack 56 arranged in an annular shape. The non-accommodated area 63 is provided with a bar code assigned to the small container 34a accommodated in the inner container accommodating rack 60 by using the bar code reader 22 (see FIG. 5) arranged radially outward of the rotation support portion 33B. This is a transmission area for reading. The barcode reader 22 can also read a barcode given to the large container 34c stored in the outer container storage rack 56.

  FIG. 11 is a cross-sectional view for explaining in detail the outer container storage rack 56 in which the large container 34c is stored. As described above, in the outer container storage rack 56, the storage portion 58 adapted to store the large container 34c as the third container is defined by the partition wall portion 56a, the support wall portion 56b, the connection wall portion 56c, and the bottom wall portion 56d. Has been established. A rib 68a extending in the up-down direction (depth direction of the housing portion 58) is formed on the partition wall portion 56a, a rib 68b extending in the up-down direction is formed on the support wall portion 56b, and a vertically extending rib 68b is formed on the connection wall portion 56c. The rib 68c is formed. One or more ribs 68a to 68c are formed and support the container main body 50a of the large container 34c with a small contact area (for example, in a state of substantially linear contact). Further, as shown in FIG. 11, the rib 68b and the rib 68c have inclined contact surfaces so that the large container 34c is inclined toward the support wall 56b. As shown in FIG. 11, by storing the large container 34 c in a posture falling down toward the support wall portion 56 b, even if the remaining amount of the reagent stored in the large container 34 c is reduced, the remaining reagents can be removed. It can be collected at a position directly below the container port 50b. That is, the reagent contained in the large container 34c can be easily dispensed to the end and used.

  A plurality of rack legs 56e (shown in FIG. 8) are formed on the bottom wall 56d of the outer container housing rack 56, and the outer container housing rack 56 is allowed to stand in a stable posture. Further, the rack leg portion 56e can also function as a positioning member when the outer container housing rack 56 is mounted on the rotation support portion 33B (receiving stand) of the reagent storage 12. For example, by inserting the rack leg portion 56e into a positioning hole formed in the rotation support portion 33B, the outer container housing rack 56 is accurately and stably positioned with respect to the rotation support portion 33B (the reagent storage 12). be able to. The bottom wall portion 56d has a plurality of joined portions (engaging holes 64a, 64b) with which joining portions (engaging pins 74a, 74b, see FIG. 1) of the support adjustment member 70 described later are engaged. ing. The details of the engagement holes 64a and 64b will be described later. In addition, as described above, the bottom wall 56d is formed with an opening (vent) for controlling the temperature of the reagent container 34 to be housed.

  As shown in FIG. 10, the reagent storage 12 can store at least two types of reagent containers 34 by using the outer container storage rack 56 and the inner container storage rack 60. However, there are cases where it is desired to accommodate more medium-sized containers 34b and small containers 34a. For example, the number of the large containers 34c may be ten, and instead, there may be a case where it is desired to accommodate thirty medium containers 34b and sixty small containers 34a. Therefore, the outer container housing rack 56 of the present embodiment may be provided with a support adjustment member 70 that adjusts the housing portion 58 adapted to accommodate the large container 34c to accommodate the medium container 34b or the small container 34a. it can.

  FIG. 1 is a perspective view showing an example of the shape of the support adjustment member 70 (spacer). The support adjustment member 70 is a medium-sized container 34b, which is a second container having a shorter length in the direction in which the support wall portion 56b and the connection wall portion 56c are opposed to each other than the large container 34c, which is a third container sized to fit the storage portion 58. And a member for positioning and accommodating the small container 34a as the first container so as to be in contact with the support wall portion 56b.

  The support adjustment member 70 is a plate-shaped member that extends substantially parallel to the partition wall portion 56a of the outer container housing rack 56 illustrated in FIG. 11 (the direction in which the support wall portion 56b and the connection wall portion 56c face each other). The support adjustment member 70 includes a support portion including ribs 70a to 70c, and the ribs 70a and 70c respectively configure a first support portion and a second support portion that are opposed to the support portion, and the first support portion includes The second support portion contacts the inner peripheral side surface 52 when the small container 34a is accommodated in the accommodation portion 58, and the second support portion contacts the inner peripheral side surface 52 when the medium container 34b is accommodated in the accommodation portion 58. In another embodiment, the support portion of the support adjustment member 70 does not consist of a plurality of ribs, but may have another suitable configuration. The first base member 70d on the lower side of the ribs 70a to 70c has a first fittable portion (engagement hole 64a) and a first fittable portion (engagement hole 64b) shown in FIG. A joining portion (engaging pin 74a) and a second joining portion (engaging pin 74b) are formed. That is, the first joint and the second joint are connected to the base member 70d of the support, and the support is connected to the first joint and the first joint by the first joint and the second joint. It is joined to the second joined portion. The above-described engaging holes 64a, 64b may be referred to as first engaging portions, and the engaging pins 74a, 74b engaged with the engaging holes 64a, 64b may be referred to as second engaging portions. The engagement of the engagement pins 74a, 74b with the engagement holes 64a, 64b allows the support adjustment member 70 to stand in a predetermined posture with respect to the bottom wall portion 56d of the housing portion 58 (for example, stand up parallel to the partition wall portion 56a). Position) and can be attached.

  As described above, when the support adjustment member 70 is attached to the housing portion 58, the bottom wall portion 56d is used. In other words, the bottom wall portion 56d has a structure in which the first engagement portion (engagement hole portions 64a, 64b) and the second engagement portion (engagement pins 74a, 74b) are engaged, so that the accommodation portion 58 There is no need to provide a member fixing mechanism for changing the size of the storage portion 58 in the circumferential direction, and a space (circumferential) required to form the storage portion 58 having a function for storing the reagent container 34 is eliminated. It is no longer necessary to secure an unnecessarily large space in the direction. That is, it is possible to provide the outer container storage rack 56 having a simple shape capable of suppressing a reduction in the storage capacity of the reagent container 34. In addition, since the support adjustment member 70 is attached using the bottom wall portion 56d which does not affect the accommodation of the reagent container 34, a sufficient contact area between the base member 70d and the bottom wall portion 56d for attachment can be secured. . As a result, the mounting of the support adjustment member 70 can be performed firmly and stably.

  Either one of the engagement holes 64a, 64b as the first engagement portion and the engagement pins 74a, 74b as the second engagement portion may have elasticity. Since one of the first engagement portion and the second engagement has elasticity, the attachment and detachment can be easily performed. For example, the engagement pins 74a and 74b can be made to have elasticity to function as a snap fit. In this case, the attachment and detachment of the support adjustment member 70 is easily performed, and a firm fixing force (holding force, support force) that maintains the posture of the support adjustment member 70 can be obtained. Specifically, the engaging pins 74a and 74b are, for example, in the form of latches, and the engaging pins 74a and 74b have elastic structures 74a1 and 74b1, respectively, and are engaged by elastic deformation of the elastic structures 74a1 and 74b1. The engagement pins 74a, 74b are prevented from separating from the engagement holes 64a, 64b due to the interference between the elastic structures 74a1, 74b1 and the base member 70d. The user may separate the engagement pins 74a, 74b from the engagement holes 64a, 64b by applying a force to the elastic structures 74a1, 74b1 to deform them. In another embodiment, the engagement holes 64a and 64b may have elasticity. In this embodiment, the engagement pins 74a and 74b are shown as the second engagement portions, and the engagement holes 64a and 64b are shown as the first engagement portions. However, another engagement method may be used. In another embodiment, an elastic member, for example, a leaf spring or a coil spring, is provided between the connection wall portion 56c and the support adjustment member 70 to urge the support adjustment member 70 toward the support wall portion 56b. You may do so. In this case, the support adjustment member 70 can be more stably attached to the bottom wall portion 56d, the medium-sized container 34b, and the small container 34a to be accommodated. As a result, the support stability of the medium-sized container 34b and the small container 34a can be further improved.

  FIG. 2 is a perspective view illustrating the first joint state and the second joint state in which the support adjustment member 70 is mounted on the outer container housing rack 56. FIG. 3 is a cross-sectional view illustrating the outer container housing rack 56 to which the support adjustment member 70 is mounted in the first joined state. FIG. 4 is a cross-sectional view illustrating the outer container housing rack 56 to which the support adjustment member 70 is mounted in the second joined state. As shown in FIGS. 2 to 4, the support portions (ribs 70 a to 70 c) of the support adjustment member 70 are in the first joined state (FIG. 3) via the engaging pins 74 a and 74 b in the rack main body 57 (FIG. 8). ), The first support side (rib 70a) of the support faces the support wall 56b of the rack body 57, and the first support side and the support wall are connected to each other. The small container 34a has a relatively small distance corresponding to the small container 34a, and the small container 34a is positioned by abutment of the first support side portion and the support wall portion 56b. The supporting portions (ribs 70a to 70c) of the support adjusting member 70 are joined to the bottom wall 56d of the rack body 57 (see FIG. 8) in the second joining state (FIG. 4) via the engaging pins 74a and 74b. When the second support side portion (rib 70c) of the support portion faces the support wall portion 56b of the rack main body 57, the second support side portion (rib 70c) of the medium container 34b is provided between the second support side portion and the support wall portion 56b. With a correspondingly large distance, the middle container 34b is positioned with the second support side and the support wall 56b abutting. That is, reagent containers 34 of different shapes can be mixed and accommodated in one type of outer container accommodation rack 56.

  In the first joint state shown in FIG. 3, the two engagement pins 74a and 74b of the support adjustment member 70 are inserted into the engagement hole 64a and the engagement hole 64b, respectively. In this case, since the engagement pins 74a and 74b to be snapped are inserted into the engagement holes 64a and 64b, the support adjustment member 70 is firmly attached to the bottom wall 56d (the outer container storage rack 56). It is attached. In addition, in order to change the attachment position of the support adjustment member 70, the operation of pulling out the engagement pins 74a and 74b from the engagement holes 64a and 64b is also facilitated. The bush 68b forming the support wall portion 56b is formed to be inclined as described above, and the reagent container 34 (large container 34c) is brought into contact with the support wall portion 56b in an inclined position. Therefore, similarly to the case of the large container 34c, the medium container 34b is accommodated in a posture inclined toward the support wall 56b, and the inclination angle is, for example, 5 °. By housing the medium-sized container 34b in a posture inclined toward the support wall 56b, even when the remaining amount of the reagent stored in the medium-sized container 34b is small, the remaining reagents can be collected at a position below the container opening 50b. Can be. That is, the reagent in the medium container 34b can be easily dispensed and used until the end.

  In the second joining state shown in FIG. 4, the two engagement pins 74a and 74b of the support adjustment member 70 are inserted into the engagement hole 64b and the engagement hole 64a, respectively. In this case, since the engagement pins 74a and 74b to be snapped are inserted into the engagement holes 64b and the engagement holes 64a, the support adjustment member 70 is firmly attached to the bottom wall 56d (the outer container housing rack 56). It is attached. As described above, the bush 68b forming the support wall portion 56b abuts the reagent container 34 (large container 34c) in a posture inclined toward the support wall portion 56b and inclines, and the inclination angle is, for example, 5 °. It is. Therefore, the small container 34a is accommodated in a posture inclined toward the support wall 56b, as in the case of the medium container 34b and the large container 34c. By storing the small container 34a in a posture inclined toward the support wall portion 56b, even when the remaining amount of the reagent contained in the small container 34a is small, the remaining reagent can be collected at a position below the container port 50b. Can be. That is, the reagent in the medium container 34b can be easily dispensed and used until the end.

  More specifically, the engagement pin 74a and the engagement pin 74b of the support adjustment member 70 are joined to the engagement hole 64a and the engagement hole 64b along the vertical direction D1 (see FIGS. 3 and 4). The engagement pin 74a and the engagement pin 74b are symmetrical with respect to an axis A (see FIGS. 3 and 4) extending along the vertical direction D1 and a horizontal direction D2 perpendicular to the vertical direction D1 (see FIGS. 3 and 4). 4), the distance between the first support side (rib 70a) and the axis A is larger than the distance between the second support side (rib 70c) and the axis A. In the first joining state shown in FIG. 3, the engaging pin 74a is joined to the engaging hole 64a, the engaging pin 74b is joined to the engaging hole 64b, and the first support side ( There is a relatively small distance between the rib 70a) and the support wall 56b corresponding to the small container 34a. In the second joining state shown in FIG. 4, the engaging pin 74a is joined to the engaging hole 64b, the engaging pin 74b is joined to the engaging hole 64a, and the second support side ( There is a relatively large distance between the rib 70c) and the support wall 56b corresponding to the medium container 34b.

  As described above, the reagent containers 34 of different sizes can be accommodated only by mounting the support adjustment member 70 on the outer container accommodation rack 56 formed so as to fit the reagent container 34 of a single shape (size). The outer container storage rack 56 can be changed. In addition, since the support adjustment member 70 can be selectively mounted in the housing portion 58 of the outer container housing rack 56 in different joining states with different orientations, as shown in FIG. (For example, the large container 34c, the medium container 34b, and the small container 34a) can be accommodated in a mixed state. Conversely, the outer container storage rack 56 that is a dedicated rack for the large container 34c can be a dedicated rack for the medium container 34b or a dedicated rack for the small container 34a. Further, the outer container housing rack 56 can be a mixed rack of the large container 34c and the medium container 34b, or a mixed rack of the large container 34c and the small container 34a.

  As described above, when the outer container housing rack 56 is changed (changed) into a dedicated rack or a mixed rack as described above, it is only necessary to select the joining state of the single-shaped support adjustment member 70, so that the support adjustment is performed. The management of the member 70 is easy. In addition, since it is not necessary to prepare a plurality of types of outer container storage racks 56 and support adjustment members 70, it is possible to contribute to a reduction in manufacturing cost. In other words, if the outer container housing rack 56 for the large container 34c and the support adjustment member 70 are prepared, the outer container housing rack 56 can be used as a rack for the small container 34a and a rack for the medium container 34b. . That is, it is necessary to prepare a plurality of types of racks according to the size of the reagent container, or to prepare a member (spacer or the like) for changing the capacity of the rack according to the size of the reagent container. The disadvantage that the manufacturing cost increases accordingly. Further, it is possible to contribute to the reduction of the manufacturing cost of the sample processing device 2 (the biochemical analyzer 1) to which the outer container housing rack 56 is mounted, and to the accessories (the outer container housing rack 56 and the like) for operating the biochemical analyzer 1. The management of the support adjustment member 70) becomes easy. Furthermore, the support adjustment member 70 has different joining states adapted to different sizes by changing its own orientation, and has different joining states by selectively joining to different joined portions of the rack body 57. Therefore, the number of joined portions (engaging holes 64a, 64b) of the rack body 57 does not need to be larger than the number of joined portions (engaging pins 74a, 74b) of the support adjustment member 70, and the rack body 57 is not required. Can reduce the complexity of the structure.

  Hereinafter, another detailed structure of the support adjustment member 70 will be described. As shown in FIGS. 3 and 4, in the horizontal direction D2, the second joint portion (the engagement pin 74b) is farther from the axis A than the second support side portion (the rib 70c). Therefore, in the second joint state shown in FIG. 4, the second support side portion (rib 70c) is separated from the second joint portion (engagement pin 74b) in order to provide a sufficient space for accommodating the medium-sized container 34b. It is further away from the support wall 56b. In another embodiment, in the horizontal direction D2, the second joint portion (engagement pin 74b) may be closer to the axis A than the second support side portion (rib 70c). Do not limit.

  The first support side (rib 70a) of the support adjustment member 70 has a first urging portion E1 for abutting on the small container 34a shown in FIG. 34a is positioned stably. Similarly, the second support side portion (rib 70c) of the support adjustment member 70 has a second urging portion E2 for contacting the medium container 34b, and the second urging portion E2 causes the medium container 34b Is positioned stably. The first urging portion E1 and the second urging portion E2 are, for example, elastic arms, are integrally formed and connected to the support portion of the support adjustment member 70, and extend downward from the tip of the harmful support portion. . Further, the shapes of the first support side portion (rib 70a) and the first biasing portion E1 are symmetrical to the shapes of the second support side portion (rib 70c) and the second biasing portion E2, for example. In another embodiment, the first biasing portion E1 and the second biasing portion E2 are another type of elastic body, and the shapes of the first support side and the second support side are not symmetric. The present invention is not limited thereto.

  As shown in FIGS. 1, 3, and 4, the support adjustment member 70 includes a first inclined portion T1 and a second inclined portion T2 connected to the support portion. The lower portion T1a of the first inclined portion T1 supports one end of the bottom of the small container 34a shown in FIG. 3, and the upper portion T1b of the first inclined portion T1 contacts the side surface of the small container 34a shown in FIG. The small container 34a is inclined as described above. Similarly, the lower part T2a of the second inclined part T2 supports one end of the bottom of the medium container 34b shown in FIG. 4, and the upper part T2b of the second inclined part T2 contacts the side surface of the medium container 34b shown in FIG. In contact, the medium container 34b is tilted as described above. The inclination angle of the small container 34a due to the support of the lower part T1a of the first inclined part T1 and the contact of the upper part T1b of the first inclined part T1 is determined by the support of the lower part T1a of the first inclined part T1 and the upper part T1b of the first inclined part T1. Is the same as the inclination angle of the medium-sized container 34b due to the contact. Further, since the size of the medium container 34b is larger than the small container 34a, the distance of the bottom of the medium container 34b to be inclined is far from the bottom wall 56d, and therefore, the thickness of the lower portion T2a of the second inclined portion T2 is It is designed so as to be larger than the thickness of the lower portion T1a of one inclined portion T1. However, the present invention is not limited to this, and the shape of the container bottom may be changed so as to be well supported by the inclined portion.

  The support adjustment member 70 further includes a grip portion 76a, and the grip portion 76a and the joints (engaging pins 74a, 74b) are connected to upper and lower ends of the support adjustment member 70 that are opposed to each other. Non-slip processing may be performed on the surface of the grip portion 76a. As the non-slip process, for example, the grip portion 76a may be subjected to unevenness processing or a non-slip coating (resin or the like), and a force may be applied to the user to attach or detach the support adjustment member 70. To make it easier to do. Further, as shown in FIGS. 1 and 3, the grip portion 76a has a first display portion W1 and a second display portion W2, and the first display portion W1 is provided on the first support side portion (rib 70a). The second display portion W2 includes information on the small container 34a displayed at a close position (illustrated as 20 mL), and the second display portion W2 is displayed at a position close to the second support side portion (rib 70c). Including information about 34b (shown as 40 mL), the user can attach the support adjustment member 70 to the first or second joined state as needed. In the present embodiment, the first display unit W1 and the second display unit W2 are provided only on one side of the holding unit 76a, but the present invention is not limited to this, and the first display unit W1 The display unit W1 and the second display unit W2 may be formed.

  The support adjustment member 70 further includes two third urging portions E3. The third urging portion E3 is connected to the support portion of the support adjustment member 70, and comes into contact with two adjacent partition portions 56a of the rack main body 57, so that the support adjustment member 70 rattles in the rack main body 57. To prevent The third biasing portion E3 is, for example, an elastic arm, is integrally formed and connected to the base member 70d of the support adjustment member 70, and extends upward from the base member 70d. The gap between the ribs 70a to 70c is used to accommodate the third urging portion E3, and provides a space where the third urging portion E3 is elastically deformed. In another embodiment, the third biasing portion E3 may be another elastic body, and the present invention is not limited thereto.

  As shown in FIG. 4, the outer container housing rack 56 has a positioning protrusion 68d on the bottom wall 56d, and a lower end of the support adjusting member 70 has a positioning recess N, and the positioning protrusion 68d and the positioning recess N Are fitted to each other so that the support adjustment member 70 can be accurately joined to the outer container storage rack 56.

  In the above-described embodiment, an example is shown in which the support adjustment member 70 is detachable from the bottom wall portion 56d. However, when the user wants to attach a mixed pattern of the reagent containers 34, the support adjustment member 70 is You may make it attach to the wall part 56d by fastening means, for example, a screw or an adhesive. In this case, even if the user selects any of the mixed patterns, the outer container housing rack 56 and the support adjustment member 70 having the same shape may be provided, so that the versatility of the parts can be improved and the cost can be reduced. Can contribute.

  In the above-described example, the support adjustment member 70 is attached to the outer container housing rack 56, and the outer container housing rack 56 is a mixture of the small container 34a, the medium container 34b, and the large container 34c, or is dedicated to the small container 34a. 34b shows a case where it can be used exclusively. In another embodiment, for example, after the inner container storage rack 60 is shaped to fit the medium-sized container 34b, a support adjustment member similar to the support adjustment member 70 is attached to the inner container storage rack 60, and the small container 34a and the medium-sized container 34b may be mixed.
