Description

  The present invention relates to an automatic analyzer, and more particularly, to an automatic analyzer including a reagent disk that accommodates a reagent container.

  An automatic analyzer that analyzes a specific component in a biological sample (specimen) such as blood or urine uses a reagent that reacts with the specific component and changes its optical characteristics. It is an apparatus that automates qualitative / quantitative analysis by measuring changes or counting the number of labels using a reagent having a label that reacts specifically with a specific component. In such an automatic analyzer, the reagent used for each measurement item is different, and depending on the measurement item, analysis is performed using two or three types of reagents. For this reason, the automatic analyzer includes a reagent disk that houses a plurality of reagent containers filled with reagents. Note that the reagent disk is provided in a reagent store having a cold insulation function in order to prevent the reagent from being deteriorated, evaporated, and the like.

  Automatic analyzers are required to reduce the size of the apparatus, increase the processing capacity, and reduce the amount of specimen / sample. On the other hand, it is desirable that the number of reagents to be accommodated is large. Generally, an automatic analyzer is provided with one or two reagent disks for accommodating reagent containers.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2010-101726) discloses a biochemical automatic analyzer that saves space by accommodating a sample container and a reagent container in one rotating tray (disc). Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2009-288094) discloses an automatic analyzer that saves space and increases the number of reagents stored by arranging two reagent disks stacked one above the other. . Patent Document 3 (Japanese Patent Laid-Open No. 2010-181423) discloses an automatic analyzer in which reagent disks are provided inside and outside a reaction disk, respectively, and the number of reagents accommodated is increased without increasing the apparatus size. Yes.

JP 2010-101726 A JP 2009-288094 A JP 2010-181423 A

  However, in the biochemical automatic analyzer disclosed in Patent Document 1, since the sample container and the reagent container are accommodated in one disk, space saving can be realized. There is concern in terms of increasing the number. In the automatic analyzers disclosed in Patent Documents 2 and 3, since two reagent-dedicated disks are provided, the number of reagents accommodated can be increased. However, the number of components increases, resulting in an increase in cost.

  Some reagents may be used less frequently or used in a small amount. For this reason, from the viewpoint of running cost and the like, it is also required that the automatic analyzer can accommodate a small volume reagent container.

  Accordingly, an object of the present invention is to provide an automatic analyzer including a reagent disk that efficiently accommodates a reagent container.

  In order to solve such a problem, the present invention includes a reagent disk having a container holding part for holding the reagent container by accommodating the reagent container from the opening, and the container holding part is provided on the reagent disk. A plurality of inner peripheral side holding portions arranged on the rotation center side, and a plurality of outer peripheral side holding portions arranged on the outer peripheral side of the reagent disk, and the outer circumference in the shape of the opening of the inner peripheral side holding portion When the shape of the opening portion of the side holding portion is overlapped, one side of the sides constituting the opening portion of the outer peripheral side holding portion and the two sides on both sides thereof are sides constituting the opening portion of the inner peripheral side holding portion The automatic analyzer is characterized in that it overlaps one side and two sides on both sides thereof, and the area of the opening of the outer peripheral holding part is smaller than the area of the opening of the inner peripheral holding part.

  ADVANTAGE OF THE INVENTION According to this invention, an automatic analyzer provided with the reagent disk which accommodates a reagent container efficiently can be provided.

<< Second Embodiment >>
Next, the automatic analyzer 1 according to the second embodiment will be described in comparison with the automatic analyzer 1 according to the first embodiment. FIG. 5 is a partially enlarged top view of the reagent disk 3 provided in the automatic analyzer 1 according to the first embodiment. FIG. 6 is a partially enlarged top view of the reagent disk 3A provided in the automatic analyzer 1 according to the second embodiment.

  As shown in FIGS. 2 and 5, the reagent disk 3 of the automatic analyzer 1 according to the first embodiment becomes narrower as the circumferential width of the shape of the opening of the outer peripheral holding part 32 becomes closer to the outer peripheral side of the reagent disk 3.

FIG. 7 is a partially enlarged perspective view showing a state in which the reagent containers (15A, 15B) are accommodated in the container holding portions (31, 32) of the reagent disk 3 provided in the automatic analyzer 1 according to the third embodiment. This is a state where the first reagent container 15A is accommodated in the side holding part 31 and the second reagent container 15B is accommodated in the outer peripheral side holding part 32. FIG. 8 is a partially enlarged perspective view showing a state in which the reagent containers (15A, 15B) are accommodated in the container holding portions (31, 32) of the reagent disk 3 provided in the automatic analyzer 1 according to the third embodiment. The second reagent container 15B is housed in the side holding part 31 and the outer peripheral side holding part 32.

  The reagent disk 3 of the automatic analyzer 1 according to the third embodiment is provided between the inner peripheral side holding part 31 and the outer peripheral side holding part 32 in addition to the reagent disk 3 of the automatic analyzer 1 according to the first embodiment. And a fitting member 34 having a concave hole 34e that fits into the convex portion 33. Other configurations are the same as those of the automatic analyzer 1 according to the first embodiment, and a description thereof will be omitted.

  The fitting member 34 can be attached to and detached from the reagent disk 3 by fitting / releasing the convex portion 33 of the reagent disk 3 and the concave hole 34 e of the fitting member 34. An opening is formed in the fitting member 34. The opening of the fitting member 34 is formed in a trapezoidal shape (isosceles trapezoidal shape), and is formed by a lower base side 34a, leg sides 34b and 34c, and an upper base side 34d. As shown in FIGS. 7 and 8, the opening of the fitting member 34 is described as an example in which a chamfering (fillet) process is performed at a corner, but the chamfering process may not be performed. Further, the fitting member 34 is formed with a concave hole 34e that fits the convex portion 33 outside the lower bottom side 34a of the opening.

  Further, as shown in FIGS. 7 and 8, the depth of the container holding portions (31, 32) is shallower than the height of the reagent containers (15A, 15B), and the reagent containers (15A, 15B) are held by the containers. When accommodated in the parts (31, 32), the upper part of the side surface of the reagent container (15 A, 15 B) protrudes from the plate surface of the reagent disk 3.

  Here, the shape of the opening portion of the fitting member 34 and the shape of the opening portion of the outer peripheral side holding portion 32 have an overlapping structure.

  As shown in FIG. 7, when the concave hole 34 e is fitted to the convex portion 33 so that the opening of the fitting member 34 is oriented toward the outer peripheral side of the reagent disk 3 relative to the concave hole 34 e, the fitting is seen from above. The lower base side 34a of the dent member 34 and the lower base side 32a (see FIG. 2) of the outer peripheral side holding portion 32 coincide, and the leg side 34b of the fitting member 34 and the leg side 32b of the outer peripheral side holding portion 32 (see FIG. 2). ) Match, the leg side 34c of the fitting member 34 and the leg side 32c (see FIG. 2) of the outer peripheral side holding portion 32 match, and the upper bottom side 34d of the fitting member 34 and the outer side holding portion 32 The bases 32d (see FIG. 2) coincide with each other.

  As shown in FIG. 7, the first reagent is attached to the inner peripheral holding portion 31 by attaching the fitting member 34 so that the opening of the fitting member 34 is oriented toward the outer peripheral side of the reagent disk 3 with respect to the recessed hole 34 e. The container 15A can be accommodated and held. Further, the second reagent container 15 </ b> B can be accommodated and held in the outer peripheral side holding portion 32 through the opening of the fitting member 34. In this manner, the fitting member 34 does not prevent the second reagent container 15B from being accommodated in the outer peripheral side holding portion 32.

  Here, as viewed from above, the outer shape of the first reagent container 15A (the triangle formed by the base 15Aa and the equal sides 15Ab and 15Ac) and the shape of the opening of the inner peripheral holding portion 31 (the base 31a and the equal sides 31b and 31c). The triangle formed by (1) is not completely coincident, and an assembly is provided in consideration of manufacturing errors and ease of attachment / detachment. That is, the outer shape of the first reagent container 15A is slightly smaller than the shape of the opening of the inner peripheral holding portion 31. For this reason, play occurs in the first reagent container 15A accommodated in the inner peripheral holding part 31, but the opening 15Ao of the first reagent container 15A is formed in consideration of play, At the time of injection, the reagent dispensing nozzle 17 (see FIG. 1) can be inserted into the opening 15Ao.

  Similarly, when viewed from above, the outer shape of the second reagent container 15B (the trapezoid formed by the lower base 15Ba, the leg sides 15Bb, 15Bc, and the upper base 15Bd) and the shape of the opening of the outer peripheral holding part 32 (lower The trapezoid formed by the bottom side 32a, the leg sides 32b and 32c, and the upper base side 32d) is not completely coincident, and is provided with consideration for manufacturing errors and ease of attachment / detachment. That is, the outer shape of the second reagent container 15B is slightly smaller than the shape of the opening of the outer peripheral holding portion 32. For this reason, play occurs in the second reagent container 15B accommodated in the outer peripheral holding part 32, but the opening 15Bo of the second reagent container 15B is formed in consideration of play, and is dispensed. Sometimes, the reagent dispensing nozzle 17 (see FIG. 1) can be inserted into the opening 15Bo.

  Further, as shown in FIG. 8, the concave hole 34e is fitted into the convex portion 33 so that the opening of the fitting member 34 is oriented toward the rotation center 3c (see FIG. 2) of the reagent disk 3 with respect to the concave hole 34e. When viewed from above, the lower base side 34a of the fitting member 34 and the lower base side 31a (see FIG. 2) of the inner circumferential side holding portion 31 coincide with each other, and the leg side 34b of the fitting member 34 and the inner circumferential side holding are viewed. A part of the equal side 31b (see FIG. 2) of the portion 31 is matched, and a part of the leg side 34c of the fitting member 34 is matched with a part of the equal side 31c (see FIG. 2) of the inner peripheral holding part 31. ing.

  As shown in FIG. 8, by holding the fitting member 34 in such a direction that the opening of the fitting member 34 is closer to the rotation center 3c (see FIG. 2) of the reagent disk 3 than the recessed hole 34e, the outer peripheral side is retained. The second reagent container 15B can be accommodated and held in the part 32. Further, when the second reagent container 15B is accommodated and held in the inner peripheral holding part 31, the second reagent container 15B is accommodated through the opening of the fitting member 34, and the opening (lower bottom side) of the fitting member 34 is received. 34a, leg sides 34b, 34c, and upper base 34d) are held on the upper side of the second reagent container 15B.

  Here, as described above, the outer shape of the second reagent container 15B is made slightly smaller than the shape of the opening of the outer peripheral holding portion 32 in consideration of play. Since the shape of the inner periphery side holding part 31 is a shape extending to the rotation center 3 c (see FIG. 2) side than the shape of the outer periphery side holding part 32, the second reagent container 15 </ b> B is connected to the inner periphery side holding part 31. The backlash in the radial direction of the reagent disk 3 when housed in is larger than the backlash when the second reagent container 15B is housed in the outer peripheral side holding portion 32. For this reason, it is assumed that the reagent dispensing nozzle 17 (see FIG. 1) cannot be inserted into the opening 15Bo. In addition, even if the amount of asobi is the same, the diameter of the second reagent container 15B accommodated in the inner peripheral holding portion 31 increases as the base angle of the triangle of the opening of the inner peripheral holding portion 31 increases (closer to 90 °). The backlash in the direction also increases. As the number of inner peripheral side holding portions 31 arranged in the circumferential direction of the reagent disk 3 is increased, the apex angle of the triangle of the inner peripheral side holding portion 31 is smaller and the base angle is larger. In the reagent disk 3 having the above, it becomes more problematic.

  On the other hand, in the reagent disk 3 of the automatic analyzer 1 according to the third embodiment, the second reagent container 15B is inserted into the opening of the fitting member 34 and is held on the upper side of the second reagent container 15B. Even if the second reagent container 15B having a smaller capacity than the first reagent container 15A is accommodated in the inner peripheral holding part 31, the second reagent container 15B is held without greatly falling to the rotation center 3c side of the reagent disk 3. Thereby, the backlash when the second reagent container 15B is accommodated in the inner peripheral side holding part 31 through the opening of the fitting member 34 is the backlash when the second reagent container 15B is accommodated in the outer peripheral side holding part 32. And the same level. Therefore, at the time of dispensing, the reagent dispensing nozzle 17 (see FIG. 1) can be inserted into the opening 15Bo.

  Further, the fitting member 34 is also used when the second reagent container 15B is accommodated in the inner peripheral holding portion 31 (see FIG. 7) when the first reagent container 15A is accommodated in the inner peripheral holding portion 31 (see FIG. 7). 8) is also attached to the plate surface of the reagent disk 3, reducing the trouble of storing the fitting member 34 in another place and the trouble of bringing the fitting member 34 stored in another place. Can be improved.
