Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a dilution component and a blood analyzer. Background Art

[0002] In the prior art, the dilution component of a blood analyzer typically collects diluent from a dilution bottle and injects it into the dilution cup of a corresponding dilution plate. The collected sample is also injected into the dilution cup and mixed to obtain a mixed solution. The mixed solution is the diluted sample solution, and the test results of the corresponding sample can be obtained by performing sample testing and analysis on the mixed solution.

[0003] The drawback of the prior art is that, in order to arrange more dilution cup slots on the dilution plate to improve the efficiency of sample detection, the dilution plate occupies a large area on the horizontal plane, and the volume of the dilution bottle itself is usually large. Since the sampling assembly for collecting and injecting liquid usually needs to be moved to different positions on the horizontal plane to collect or inject liquid into the dilution bottle and the dilution cup slot respectively, the dilution assembly with the dilution bottle and the dilution plate arranged side by side on the horizontal plane usually occupies a large area on the horizontal plane, and there always needs to be free space above the dilution assembly for use when the sampling assembly moves, so that the dilution assembly needs to occupy a large space in the blood analyzer, that is, the space utilization rate of the dilution assembly is low.

When the first drawer moves in the second target direction, the pressure contact can be moved closer to or away from the lock buckle; the press-type elastic self-locking mechanism is used to: when the pressure contact and the lock buckle are in the unlocked state and the pressure contact applies pressure to the lock buckle, the pressure contact and the lock buckle are locked so that the pressure contact and the lock buckle enter the locked state; when the pressure contact and the lock buckle are in the locked state and the pressure contact applies pressure to the lock buckle, the pressure contact and the lock buckle are unlocked so that the pressure contact and the lock buckle enter the unlocked state.

For example, they can mean fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or connection through an intermediate medium.

[0036] This application proposes a dilution component, see Figure 1 and Figure 2 , Figure 1 This is one of the exploded structural diagrams of an embodiment of the dilution assembly of the present application. Figure 2 This is the second structural explosion diagram of an embodiment of the dilution component of the present application. Figure 1 and Figure 2 As shown, the dilution assembly includes a dilution plate 101 , a receiving shell 102 and at least one dilution bottle 103 .

[0037] A plurality of dilution cup slots are provided on the top of the dilution plate 101 .

[0038] Among them, such as Figure 1 and Figure 2 As shown, the dilution plate 101 may be provided with a plurality of dilution cup slots, and the plurality of dilution cup slots may be arranged in an array or in other manners, which are not limited here.

[0039] The housing 102 forms a receiving space and includes a support plate 1021 on which the dilution plate 101 is disposed. The dilution bottle 103 is used to store diluent, and the receiving space is used to receive at least part of the dilution bottle 103 .

[0040] The housing shell 102 may include a storage space located below the support plate 1021. The storage space may be used to accommodate at least a portion of the body of the dilution bottle 103. The sampling assembly may collect the diluent through the bottle mouth of the dilution bottle 103 and then inject the collected diluent into the dilution cup slot of the dilution plate 101.

[0041] The first projection of the bottle mouth of each dilution bottle 103 on the target projection plane does not overlap with the fourth projection of the dilution plate 101 on the target projection plane, and the third projection of each dilution bottle 103 on the target projection plane partially overlaps with the fourth projection of the dilution plate 101 on the target projection plane.

[0042] Among them, the accommodating space, the support plate 1021 and the dilution plate 101 are arranged in sequence along the first target direction D1, the dilution cup groove is located on the side of the dilution plate 101 away from the accommodating space, the projection direction of the first projection, the projection direction of the third projection, the projection direction of the fourth projection and the first target direction D1 are all parallel to each other, the projection directions of the first projection, the third projection and the fourth projection are respectively the same as or opposite to the first target direction D1, the first target direction D1 is perpendicular to the target projection plane, and the target projection plane is the plane on which the dilution plate 101 is arranged on the support plate.

[0043] In one embodiment, the first projection of the opening of each dilution bottle 103 on the target projection plane and the fifth projection of the support plate 1021 on the target projection plane at least partially do not overlap. By ensuring that the first projection of the opening of each dilution bottle 103 on the target projection plane and the fourth projection of the dilution plate 101 on the target projection plane do not overlap, and that the first projection of the opening of each dilution bottle 103 on the target projection plane and the fifth projection of the support plate 1021 on the target projection plane do not overlap, it is possible to ensure that the entire space between the opening of the dilution bottle 103 and the position where the corresponding sampling assembly will pass in the first target direction D1 is free of the dilution plate 101, and that the support plate 1021 is partially or completely free of the space. This ensures that the sampling assembly can pass through the target projection plane and enter the dilution bottle 103 from the opening of the corresponding dilution bottle 103 to collect the dilution liquid, while the sampling assembly will not be obstructed by the support plate 1021 when moving in the direction opposite to the first target direction D1.

[0044] By partially overlapping the third projection of each dilution bottle 103 on the support plate 1021 with the fourth projection of the dilution plate 101 on the support plate 1021 , part of the body of each dilution bottle 103 can be positioned directly below the dilution plate 101 .

[0045] In one example, if Figure 1 and Figure 2 As shown, the dilution plate 101 is located directly above the accommodating shell 102, that is, the accommodating shell 102 and the dilution plate 101 are arranged in sequence along the first target direction D1, and the plane of the accommodating shell 102 facing the dilution plate 101 is the target projection plane, and the dilution plate 101 can be arranged on the target projection plane, and the first target direction D1 is perpendicular to the target projection plane.

[0046] Based on the above method, in the conventional technology, the entire dilution bottle 103 and the dilution plate 101 are usually placed adjacent to each other on the corresponding support plate 1021, so that the area occupied by the support plate 1021 is relatively large. Figure 1 and 2 As shown, based on the technical solution of the present application, by setting part of the bottle body of each dilution bottle 103 directly below the dilution plate 101, only the bottle mouth of the dilution bottle 103 is exposed in the first target direction D1 for the sampling component to collect the dilution liquid, compared with the traditional technology, the area directly below the support plate 1021 can be effectively utilized to reduce the area occupied by the support plate 1021 of the dilution component, thereby reducing the area occupied by the entire dilution component, thereby improving the space utilization rate of the dilution component.

[0047] It should be noted that, since the space above the dilution component is usually reserved for the sampling component or other components to move through, the dilution component has more available space in its vertical direction (first target direction D1). In this case, the larger the area of ​​the dilution component of the same volume in the horizontal direction (the horizontal direction can specifically refer to the direction parallel to the target projection plane), the larger the total volume of the equipment where the dilution component is located, that is, the lower the space utilization rate of the dilution component. To solve this problem, based on the above method, part of the area of ​​the dilution bottle on the target projection plane is overlapped with part of the area of ​​the dilution plate on the target projection plane, thereby reducing the area required to be occupied by the support plate 1021 of the dilution component in the horizontal direction, effectively utilizing the area under the support plate 1021, and thereby reducing the area required to be occupied by the entire dilution component, thereby improving the space utilization rate of the dilution component.

[0048] Different from the prior art, in the technical solution of the present application, a plurality of dilution cup slots are provided on the top of the dilution plate; a accommodating shell forms a accommodating space, the accommodating shell includes a support plate, and the dilution plate is arranged on the support plate; the dilution bottle is used to store the dilution liquid, and the accommodating space is used to accommodate the dilution bottle; the first projection of the bottle mouth of each dilution bottle on the target projection plane does not overlap with the fourth projection of the dilution plate on the target projection plane, and the third projection of each dilution bottle on the target projection plane partially overlaps with the fourth projection of the dilution plate on the target projection plane; the accommodating space and the dilution plate are arranged in sequence along the first target direction, the dilution cup slots are located on the side of the dilution plate away from the accommodating space, the projection direction of the first projection, the projection direction of the third projection, the projection direction of the fourth projection are parallel to the first target direction, the first target direction is perpendicular to the target projection plane, and the target projection plane is the plane on which the dilution plate is arranged on the support plate. Compared with the traditional technology of arranging the dilution bottle and the dilution plate adjacent to each other on the same support plate, based on the above method, there can be enough space outside the bottle mouth of the dilution bottle for the corresponding sampling component to collect the dilution liquid, and some dilution bottles can be located directly below the dilution plate. The dilution bottles, the support plate and the dilution plate are arranged in a layout with partial overlapping areas in the first target direction. Effective utilization of the area below the support plate can reduce the area corresponding to the part of the dilution bottles located directly below the dilution plate in the total area of ​​the support plate, that is, reduce the area occupied by the support plate of the dilution component, and then reduce the area occupied by the entire dilution component, thereby improving the space utilization rate of the dilution component.

[0049] In one embodiment, if Figure 1 and Figure 2 As shown, the support plate 1021 is provided with at least one dilution hole 1022 , and the at least one dilution hole 1022 is provided adjacent to the dilution plate 101 .

[0050] The first projection of the bottle mouth of each dilution bottle 103 on the target projection plane at least partially overlaps with the second projection of the corresponding dilution hole 1022 on the target projection plane.

[0051] The projection direction of the first projection, the projection direction of the second projection, the projection direction of the third projection, the projection direction of the fourth projection, and the first target direction D1 are parallel.

[0052] Specifically, the first projection of the bottle mouth of each dilution bottle 103 on the target projection plane at least partially overlaps with the second projection of the corresponding dilution hole 1022 on the target projection plane, and the third projection of each dilution bottle 103 on the target projection plane partially overlaps with the fourth projection of the dilution plate 101 on the target projection plane.

[0053] The second projection and the fourth projection are independent of each other on the target projection plane, that is, there is no overlapping portion between the second projection and the fourth projection.

[0054] Since there is no support plate 1021 in the area within the dilution hole 1022, by ensuring that the first projection of the bottle mouth of each dilution bottle 103 on the support plate 1021 at least partially overlaps with the corresponding dilution hole 1022, it is possible to ensure that the sampling assembly can pass through the dilution hole 1022 and enter the dilution bottle 103 from the bottle mouth of the corresponding dilution bottle 103 to collect the dilution liquid.

[0055] By partially overlapping the third projection of each dilution bottle 103 on the support plate 1021 with the fourth projection of the dilution plate 101 on the support plate 1021 , part of the body of each dilution bottle 103 can be positioned directly below the dilution plate 101 .

[0056] In one example, if Figure 1 and Figure 2 As shown, the dilution plate 101 is located directly above the accommodating shell 102, that is, the accommodating shell 102 and the dilution plate 101 are arranged in sequence along the first target direction D1, and the plane of the accommodating shell 102 facing the dilution plate 101 is the target projection plane, and the dilution plate 101 can be arranged on the target projection plane, and the first target direction D1 is perpendicular to the target projection plane.

[0057] The housing 102 is provided with a receiving space for storing the dilution bottle 103 . Part of the dilution bottle 103 in the receiving space is located directly below the dilution plate 101 , while the other part of the bottle is at least partially located directly below the dilution hole 1022 .

[0058] Taking the first target direction D1 as the vertical direction, with the dilution plate 101 on top and the accommodating shell 102 on the bottom, first, by partially overlapping the third projection with the fourth projection, a portion of the dilution bottle 103 without a bottle mouth can be located directly below the dilution plate 101.

[0059] Second, by making the first projection partially or completely overlap with the second projection, the other part of the bottle body of the dilution bottle 103 where the bottle mouth is provided can be not located directly below the dilution plate 101, but at least partially located directly below the dilution hole 1022, and the corresponding sampling assembly can pass through the dilution hole 1022 and the bottle mouth of the dilution bottle 103 through a sampling needle or other type of sampling device in the opposite direction of the first target direction D1 to enter the dilution bottle 103 to collect the dilution liquid.

[0060] Based on the above method, in the conventional technology, the entire dilution bottle 103 and the dilution plate 101 are usually placed adjacent to each other on the corresponding support plate 1021, so that the area occupied by the support plate 1021 is relatively large. Figure 1 and 2As shown, based on the technical solution of the present application, by arranging part of the bottle body of each dilution bottle 103 directly below the dilution plate 101, and only arranging the bottle mouth of the dilution bottle 103 and the dilution plate 101 adjacent to each other on the corresponding support plate 1021, the area required to be occupied by the plate surface of the support plate 1021 can be reduced compared with the traditional technology. The reduced part is the area required to be occupied by the part of the bottle body of the dilution bottle 103 arranged directly below the dilution plate 101, thereby reducing the area required to be occupied by the support plate 1021 of the dilution component, thereby improving the space utilization rate of the dilution component.

[0061] For an example, see Figures 4 to 14 , Figure 4 This is one of the top views of an embodiment of the dilution hole and the dilution plate of the present application. Figure 5 This is the second top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 6 This is the third top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 7 This is the fourth top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 8 This is the fifth schematic top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 9 This is the sixth schematic top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 10 This is the seventh schematic top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 11 This is the eighth schematic top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 12 This is a ninth top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 13 This is a tenth top view of an embodiment of the dilution hole and the dilution plate of the present application. Figure 14 This is the eleventh top view schematic diagram of an embodiment of the dilution hole and the dilution plate of the present application.

[0062] First, as Figures 4 to 14 As shown, from the top view of the dilution hole and the dilution plate, it can be seen that the number of the at least one dilution hole 1022 can be 1, 5, 8, 10, 11 or other numbers, which are not limited here.

[0063] Second, if Figure 4 、 Figures 6 to 8 As shown in FIG. 1 , it can be seen from the top view of the dilution hole and the dilution plate that at least one dilution hole 1022 can be arranged on one side of the dilution plate 101 , for example, Figure 4 The dilution holes 1022 are all arranged on the left side of the dilution plate 101. Figure 6 The dilution holes 1022 are all arranged on the right side of the dilution plate 101. Figure 7 The dilution holes 1022 are all arranged on the upper side of the dilution plate 101. Figure 8 The dilution holes 1022 are all arranged on the lower side of the dilution plate 101.

[0064] Third, if Figures 9 to 11 As shown in the top view of the dilution hole and dilution plate, at least one dilution hole 1022 can be disposed on opposite sides of the dilution plate 101, for example, on the left and right sides. Furthermore, the number of dilution holes 1022 disposed on opposite sides of the dilution plate 101 can be equal or unequal, without limitation. Furthermore, the number of dilution plates located between the dilution holes 1022 on both sides can be one, two, three, five, or another number, without limitation.

[0065] Fourth, if Figure 12 As shown, from the top view of the dilution holes and the dilution plates, it can be seen that at least one dilution hole 1022 can be arranged in the middle of two dilution plates 101 , that is, more than two dilution plates 101 can be respectively arranged on opposite sides of all the dilution holes 1022 .

[0066] Fifth, if Figure 13 As shown, from the top view of the dilution hole and the dilution plate, it can be seen that at least one dilution hole 1022 can be respectively arranged on two adjacent sides of the dilution plate 101, such as the left side and the bottom side, or the bottom side and the right side, or other adjacent sides, which are not limited here.

[0067] Sixth, as Figure 14 As shown, from the top view of the dilution hole and the dilution plate, it can be seen that at least one dilution hole 1022 can be respectively arranged on three adjacent sides of the dilution plate 101, such as the left side, the bottom side and the right side, or other three adjacent sides, which is not limited here.

[0068] Seventh, at least one dilution hole 1022 may be disposed around the dilution plate 101 .

[0069] As can be seen from the above, the dilution holes 1022 and the dilution plate 101 can be arranged in any manner on the support plate 1021. The above are only some examples, and the specific arrangement can be determined according to actual needs. There is no limitation here. It is only necessary to ensure that the areas of the dilution holes 1022 and the dilution plate 101 on the target projection plane do not overlap, and the body of the dilution bottle 103 and the area of ​​the dilution plate 101 on the target projection plane partially overlap, and the body of the dilution bottle 103 is located below the dilution plate 101, that is, the body of the dilution bottle 103 does not block the space of the dilution plate 101 in the first target direction.

[0070] In one embodiment, see Figure 3 , Figure 3 This is a structural diagram of an embodiment of the first pumping plate of the present application. Figure 3As shown, the dilution assembly further includes a first pumping plate 104 and a bottom plate 105 .

[0071] The accommodating shell 102 is disposed on the first drawer plate 104 , and the accommodating shell 102 is fixedly connected to the first drawer plate 104 .

[0072] The first drawer 104 is disposed on the bottom plate 105 and is movable relative to the bottom plate 105 . The first drawer 104 is configured to move in a second target direction D2 parallel to the plane of the bottom plate 105 on which the first drawer 104 is disposed.

[0073] Specifically, if Figure 1 and Figure 2 As shown, the second target direction D2 can be specifically as shown in the figure. The user can apply a pulling force along the second target direction D2 to the first drawer 104, so that the first drawer 104 moves along the second target direction D2 relative to the base plate 105, and the first drawer 104 and the dilution plate 101, the accommodating shell 102 and the dilution bottle 103 arranged thereon are pulled out relative to the base plate 105. Similarly, the user can also apply a pushing force along the second target direction D2 to the first drawer 104, so that the first drawer 104 moves along the opposite direction of the second target direction D2 relative to the base plate 105, and the first drawer 104 and the dilution plate 101, the accommodating shell 102 and the dilution bottle 103 arranged thereon are pushed in relative to the base plate 105.

[0074] In one example, the second target direction D2 may be parallel to the target projection plane. In this case, the second target direction D2 may also be perpendicular to the first target direction D1.

[0075] Based on the above method, the user can choose to push and pull the first drawer 104 to move the first drawer 104 and the dilution plate 101, the accommodating shell 102 and the dilution bottle 103 arranged thereon in the second target direction D2 relative to the base plate 105 to perform device maintenance or other operations on the dilution component, thereby improving the reliability of the dilution component.

[0076] Alternatively, as Figure 1 and Figure 2 As shown, the first drawer 104 has a pressure contact 1041, and the bottom plate 105 has a lock 1051. The lock 1051 and the pressure contact 1041 constitute a press-type elastic self-locking mechanism. When the first drawer 104 moves in the second target direction D2, the pressure contact 1041 can be moved closer to or away from the lock 1051.

[0077] Push-type elastic self-locking mechanism is used for:

[0078] When the pressure contact 1041 and the lock buckle 1051 are in the unlocked state and the pressure contact 1041 applies pressure to the lock buckle 1051 , the pressure contact 1041 and the lock buckle 1051 are locked so that the pressure contact 1041 and the lock buckle 1051 enter the locked state.

[0079] When the pressure contact 1041 and the lock buckle 1051 are in the locked state and the pressure contact 1041 applies pressure to the lock buckle 1051 , the pressure contact 1041 and the lock buckle 1051 are unlocked so that the pressure contact 1041 and the lock buckle 1051 enter the unlocked state.

[0080] Specifically, it should be noted that in the press-type elastic self-locking mechanism, when the pressure contact 1041 and the lock buckle 1051 are separated, if the pressure contact 1041 is forced to resist the lock buckle 1051, the lock buckle 1051 can be triggered to lock the pressure contact 1041, so that the two can be locked. When the pressure contact 1041 and the lock buckle 1051 are locked, if the pressure contact 1041 is forced to resist the lock buckle 1051 again, the lock buckle 1051 can be triggered to release the pressure contact 1041, so that the two can be unlocked.

[0081] By providing a pressure contact 1041 on the first drawer 104 and a lock buckle 1051 on the bottom plate 105, a press-type elastic self-locking mechanism is formed, which allows the user to apply a pushing force to the first drawer 104 when needed to lock or unlock the first drawer 104 and the bottom plate 105. When locked, the stability between the first drawer 104 and the bottom plate 105 can be improved, and the possibility of the first drawer 104 being shaken out during the dilution assembly due to inspection operations or other normal operations can be reduced as much as possible, thereby further improving the reliability of the dilution assembly.

[0082] Alternatively, as Figure 2 and Figure 3 As shown, a first clamping member 1052 is provided on the top of the base plate 105, and a second clamping member 1042 is provided on the bottom of the first drawer plate 104. The first clamping member 1052 is used to clamp with the second clamping member 1042 when the first drawer plate 104 and the base plate 105 are in a target relative position relationship.

[0083] Specifically, during the movement of the first drawer 104 along the second target direction D2, if the second clamping member 1042 is moved to the first clamping member 1052, the first clamping member 1052 can be used to make the first drawer 104 and the base plate 105 be in a target relative position relationship. At this time, the first clamping member 1052 will be clamped with the second clamping member 1042 that has moved to its position, so that the first drawer 104 drawn out relative to the base plate 105 is stabilized in the target relative position relationship through the clamping structure. The user can maintain or use the first drawer 104 or the devices thereon at this time, thereby improving the safety and reliability of the user when maintaining or using the first drawer 104 or the devices thereon.

[0084] For example, the first clamping member 1052 can be a convex member, and the second clamping member 1042 can be a concave member. The two can also be reversed, or a combination of other types of clamping members can be determined according to actual needs and is not limited here.

[0085] Alternatively, as Figure 1 and Figure 2 As shown, the dilution assembly further includes a second pumping plate 106 .

[0086] The second drawer 106 is disposed on the first drawer 104 and is movable relative to the first drawer 104 . The dilution bottle 103 is disposed on the second drawer 106 and is configured to move in the second target direction D2 to allow the dilution bottle 103 to enter or leave the accommodation space.

[0087] Specifically, by arranging the dilution bottle 103 on the second drawer 106, when the second drawer 106 moves relative to the first drawer 104 along the second target direction D2, the dilution bottle 103 enters or leaves the accommodation space, thereby making it convenient for the user to accommodate or replace the dilution bottle.

[0088] In practice, the user can choose to apply force to the first drawer plate 104 or the second drawer plate 106 to pull it out according to their own needs to perform corresponding operations. For example, by pulling out the first drawer plate 104, all devices (including the second drawer plate 106) provided on the first drawer plate 104 can be used or maintained, which is relatively laborious and complicated. However, by pulling out the second drawer plate 106, all devices on the second drawer plate 106 can be used or maintained (such as replacing the dilution bottle 103), which is relatively labor-saving and simple. Based on the above method, the flexibility of use of the dilution component can be improved, and the user experience can be improved.

[0089] Furthermore, a first magnetic member 1023 is provided on the accommodating shell 102, and a second magnetic member 1061 is provided on the second drawer 106. The first magnetic member 1023 is used to be magnetically fixed to the second magnetic member 1061 when the second drawer 106 moves to allow the dilution bottle 103 to enter the accommodating space.

[0090] Specifically, the first magnetic part 1023 and the second magnetic part 1061 can be two magnetic parts that can be magnetically attracted to each other, such as two magnets, or a magnet and a metal part, or they can also be other types of magnetic parts that can be magnetically attracted to each other. The specific requirements can be determined and are not limited here.

[0091] Based on the above approach, when the user pushes the second drawer 106 into the accommodation space, the relative positional relationship between the first magnetic member 1023 and the second magnetic member 1061 can be stabilized by magnetic attraction, thereby improving the safety and reliability of the dilution assembly.

[0092] In one embodiment, a sealing film is provided on the dilution plate 101 , and the sealing film covers all the dilution cup slots.

[0093] Specifically, the sealing film can be an aluminum sealing film, which can cover all the dilution cup slots to prevent the sample from causing biological contamination to the dilution plate 101, thereby improving the accuracy and safety of each sample detection, thereby improving the reliability of the dilution component.

[0094] In one example, if Figures 1 to 3 As shown, first, a thrust can be applied to the first drawer plate 104 to trigger the unlocking of the pressure contact 1041 and the lock 1051; second, the first drawer plate 104 can be pulled out to replace the dilution plate 101; third, the second drawer plate 106 can be pulled out to replace the dilution bottle; fourth, the second drawer plate 106 can be pushed in to magnetically adsorb the first magnetic member 1023 and the second magnetic member 1061; fifth, the first drawer plate 104 can be pushed in to lock the pressure contact 1041 and the lock 1051; sixth, the blood analyzer can be controlled to perform sample testing. For example, the corresponding sampling component can be controlled to add the sample and the diluent into the dilution cup slot respectively to obtain a mixed solution, and the mixed solution is transported to the detection component for card strip incubation, card strip testing to obtain test results, and the tested card strip containing the sample is discarded.

[0095] This application also proposes a blood analyzer, see Figure 15 , Figure 15 FIG. 1 is a structural diagram of an embodiment of a blood analyzer of the present application. Figure 15 As shown, the blood analyzer 20 includes a dilution component 21 and a sampling component 22. The dilution component 21 can be the dilution component described in any of the above embodiments, which will not be described again here.

[0096] The sampling assembly 22 is used to collect the diluent from the dilution bottle 103 and inject the collected dilution into the dilution cup.

[0097] Different from the prior art, in the technical solution of the present application, a plurality of dilution cup slots are provided on the top of the dilution plate; a accommodating shell forms an accommodating space, the accommodating shell includes a support plate, and the dilution plate is arranged on the support plate; the dilution bottle is used to store the dilution liquid, and the accommodating space is used to accommodate the dilution bottle; the first projection of the bottle mouth of each dilution bottle on the target projection plane does not overlap with the fourth projection of the dilution plate on the target projection plane, the first projection of the bottle mouth of each dilution bottle on the target projection plane does not overlap with the fifth projection of the support plate on the target projection plane at least partially, and the third projection of each dilution bottle on the target projection plane partially overlaps with the fourth projection of the dilution plate on the target projection plane; the accommodating space and the dilution plate are arranged in sequence along the first target direction, the dilution cup slots are located on the side of the dilution plate away from the accommodating space, the projection direction of the first projection, the projection direction of the third projection, the projection direction of the fourth projection are parallel to the first target direction, the first target direction is perpendicular to the target projection plane, and the target projection plane is the plane on which the dilution plate is arranged on the support plate. Compared with the traditional technology of arranging the dilution bottle and the dilution plate adjacent to each other on the same support plate, based on the above-mentioned method of the present application, there can be enough space outside the bottle mouth of the dilution bottle for the corresponding sampling component to collect the dilution liquid, and some dilution bottles can be located directly below the dilution plate. The dilution bottles, the support plate and the dilution plate are arranged in a layout with partial overlapping areas in the first target direction. Effective utilization of the area below the support plate can reduce the area corresponding to the part of the dilution bottle located directly below the dilution plate in the total area of ​​the support plate, that is, reduce the area occupied by the support plate of the dilution component, and then reduce the area occupied by the entire dilution component, thereby improving the space utilization rate of the dilution component.

[0098] In one embodiment, the sampling component 22 is further configured to:

[0099] Collect blood sample liquid and inject the collected blood sample liquid into the dilution cup tank.

[0100] The diluent and the blood sample in the dilution cup are mixed to obtain a mixed solution, which is used for sample detection.

[0101] Specifically, the sampling component 22 can collect blood sample liquid from a corresponding blood sample component (such as a sample tube), and can also collect blood sample liquid from other types of components for storing blood sample liquid, which is not limited here.

[0102] Alternatively, as Figure 15 As shown, the blood analyzer 20 may further include a detection component 23 .

[0103] The sampling component 22 is further used to collect the mixed liquid from the dilution cup tank and transport the collected mixed liquid to the detection component 23. The detection component 23 is used to perform sample detection on the mixed liquid to obtain the detection result of the blood sample liquid.

[0104] In one example, if Figures 1 to 3 As shown, first, a thrust can be applied to the first drawer plate 104 to trigger the unlocking of the pressure contact 1041 and the lock 1051; second, the first drawer plate 104 is pulled out to replace the dilution plate 101; third, the second drawer plate 106 is pulled out to replace the dilution bottle; fourth, the second drawer plate 106 is pushed in to magnetically adsorb the first magnetic member 1023 and the second magnetic member 1061; fifth, the first drawer plate 104 is pushed in to lock the pressure contact 1041 and the lock 1051; sixth, the blood analyzer 20 is controlled to perform sample testing. For example, the corresponding sampling component 22 can be controlled to add the sample in the blood sample component and the diluent in the dilution component 21 to the dilution cup slot of the dilution component 21 respectively to obtain a mixed solution, and the mixed solution is transported to the detection component 23 for card strip incubation, card strip testing to obtain test results, and discarding the tested card strip containing the sample.
