Specifically, the reagent cartridge positioning block 210 is positioned and fixed with the reagent bottle cover 110 of the reagent cartridge 100. In addition, the kit 100 further includes a magnetic bead bottle 120, and the magnetic bead bottle 120 is disposed in the reagent bottle cover 110 and can rotate relative to the reagent bottle cover 110. When the magnetic bead bottle is matched with the reagent disk 200, a transmission mechanism 220 matched with the magnetic bead bottle 120 is arranged on the reagent disk 200, and a clamping mechanism matched with the transmission mechanism is arranged on the magnetic bead bottle 120. The following describes the matching structure of the magnetic bead bottle 120 and the reagent disk 200 in detail with reference to specific drawings.

Referring to fig. 2, fig. 2 shows a schematic structural diagram of a kit 100 according to an embodiment of the present utility model. Which includes a reagent bottle housing 110 and a magnetic bead bottle 120 disposed within the reagent bottle housing 110. Wherein the magnetic bead bottle 120 is rotatably connected with the reagent bottle cover 110.

In addition, the kit 100 may further include a reagent bottle 130. Referring also to fig. 3, fig. 3 shows a schematic structural diagram of the reagent bottle cover 110, and when the reagent bottle cover 110 is specifically arranged, a containing cavity is arranged on the reagent bottle cover 110; the kit 100 further comprises at least one reagent bottle 130 secured within the receiving cavity 113. As shown in fig. 2, the number of reagent bottles 130 is two, and two reagent trays 200 are arranged side by side. When in arrangement, the accommodating cavity 113 for accommodating the reagent bottle 130 is arranged at intervals from the cavity 114 for accommodating the magnetic bead bottle 120, and the two cavities are arranged side by side. So that the reagent bottles 130 and the magnetic bead bottles 120 located in the reagent bottle case 110 can be arranged in a single row.

As an alternative, the two cavities are arranged in a staggered manner along the height direction of the reagent bottle cover 110, so that a height difference exists between the two cavities, thereby ensuring that the overall heights of the reagent bottle 130 and the magnetic bead bottle 120 are approximately flush when arranged in the reagent bottle cover 110.

Referring to fig. 3 and 4 together, fig. 4 shows the structure of the magnetic bead bottle 120. When the magnetic bead bottle 120 is matched with the reagent bottle sleeve 110, the reagent bottle sleeve 110 is provided with a buckle 115, and the corresponding magnetic bead bottle 120 is provided with an annular clamping groove 124 which is in running fit with the buckle 115.

As shown in fig. 3, the cavity 114 of the reagent bottle sleeve 110 for carrying the magnetic bead bottle 120 is a circular cavity, the size of the circular cavity matches the size of the magnetic bead bottle 120, one end of the outer side wall of the cavity 114 is provided with a plurality of buckles 115, and the plurality of buckles 115 are arranged around the axis of the cavity 114. Illustratively, the catch 115 is disposed at the bottom end of the sidewall of the cavity 114. As shown in fig. 4, the annular clamping groove 124 is formed on the outer side wall of the magnetic bead bottle 120, and when specifically formed, two annular protrusions are formed on the outer side wall of the magnetic bead bottle 120 and are arranged at intervals along the length direction of the magnetic bead bottle 120, and the annular clamping groove 124 is formed between the two annular protrusions. Upon engagement, as shown in fig. 2, the clasp 115 snaps into the annular slot 124 and is rotatable within the annular slot 124 about the axis of the magnetic vial 120. It should be understood that the above-mentioned buckle 115 only limits the movement of the magnetic bead bottle 120 in the axial direction, and the magnetic bead bottle 120 can rotate around its own axis under the cooperation of the buckle 115 and the annular clamping groove 124.

As an alternative, the reagent bottle sleeve 110 is provided with a manual gripping part 111 and/or a robot gripping part. The manual gripping portion 111 and the mechanical gripping portion 112 may be used to grip the reagent bottle cover 110 to transfer the reagent cartridge 100 by gripping the reagent bottle cover 110. In the specific setting, only the manual grasping portion 111, or only the mechanical grasping portion 112, or both the manual grasping portion 111 and the mechanical grasping portion 112 may be provided.

As an alternative, the mechanical gripping portion 112 is a groove provided in the reagent bottle cover 110. The recess is provided in the outer sidewall of the reagent bottle sleeve 110. So as to facilitate the grabbing of the manipulator.

Referring to fig. 4 and 5 together, fig. 5 shows a cross-sectional view of a magnetic bead bottle. When the reagent disk 200 is assembled, the engaging structure of the magnetic bead bottle 120 includes a first engaging structure 121 and a second engaging structure 122. The first locking structure 121 and the second locking structure 122 are located at one end of the magnetic bead bottle 120 facing the reagent disk 200, so as to ensure that the locking structure of the magnetic bead bottle 120 can be matched with the reagent disk 200 when the reagent disk 200 is matched with the reagent kit 100.

When the first engaging structure 121 and the second engaging structure 122 are specifically disposed, the first engaging structure 121 and the second engaging structure 122 are arranged at intervals, and the first engaging structure 121 and the second engaging structure 122 are arranged on both sides of the axis of the magnetic bead bottle 120. In addition, the first engaging structure 121 and the second engaging structure 122 are provided at different heights. For example, the height of the first engaging structure 121 is H1, and the height of the second engaging structure 122 is H2, then: h1 > H2, or H1 < H2. When the heights of the first clamping structure 121 and the second clamping structure 122 are different, the first clamping structure 121 and the second clamping structure 122 are convenient to collide with the transmission mechanism 220 on the reagent disk 200 when being inserted into the driving structure on the reagent disk 200, and the first clamping structure 121 and the second clamping structure 122 are convenient to cooperate with the transmission mechanism 220.

For example, referring to fig. 1 and fig. 4 together, the transmission mechanism 220 on the reagent disk 200 includes a driving post 221 and two engaging protrusions 222 disposed on the driving post 221, when the magnetic bead bottle 120 is matched with the transmission mechanism 220, the driving post 221 is inserted between the first engaging structure 121 and the second engaging structure 122, and when the driving post 221 rotates, the two engaging protrusions 222 are respectively pressed against the first engaging structure 121 and the second engaging structure 122 in a one-to-one correspondence manner, so as to drive the magnetic bead bottle 120 to rotate. When the magnetic bead bottle 120 is inserted into the transmission mechanism 220, since the first clamping structure 121 and the second clamping structure 122 have different heights, if there is a collision between the clamping protrusion 222 and one of the clamping structures, only one of the clamping structures collides with the other clamping structure, and at this time, the assembly can be completed by relatively rotating the magnetic bead bottle 120, so that the difficulty in the assembly can be reduced.

As an alternative, when the first clamping structure 121 and the second clamping structure 122 are specifically arranged, a first conical guiding structure is arranged at one end of the first clamping structure 121 away from the magnetic bead bottle 120; and/or, a second conical guiding structure is arranged at one end of the second clamping structure 122 away from the magnetic bead bottle 120. When the first taper guiding structure and the second taper guiding structure are provided, the first taper guiding structure and the second taper guiding structure are respectively provided at one end of the first engaging structure 121 and one end of the second engaging structure 122, which face the reagent disk 200. As an example, only the first engagement structure 121 may be provided with a first tapered guide structure; alternatively, only the second engaging structure 122 may be provided with a second tapered guiding structure; alternatively, the first engagement structure 121 and the second engagement structure 122 are provided with a first tapered guide structure and a second tapered guide structure, respectively.

When the guiding structure is arranged, when the two clamping structures collide with the clamping protrusion 222, the insertion direction of the magnetic bead bottle 120 is guided through the conical guiding structure, so that the reliability of correct connection between the magnetic bead bottle 120 and the transmission structure on the reagent disk 200 is greatly improved, and the situation that the two are mutually collided is effectively avoided.

As an alternative, the magnetic bead bottle 120 is further provided with a toothed ring 123; the toothed ring 123 is disposed coaxially with the magnetic bead bottle 120. Illustratively, the toothed ring 123 is disposed at an end of the magnetic bead bottle 120 that faces the reagent disk 200. And when the toothed ring 123 is arranged, the toothed ring 123 and the magnetic bead bottle 120 can be in an integrated structure. I.e. the toothed ring 123 is made directly on the outer side wall of the magnetic bead bottle 120. When the magnetic bead bottle 120 is inserted into the reagent bottle case 110, the toothed ring 123 is exposed outside the reagent bottle case 110 so as to be connected to the reagent disk 200. The toothed ring 123 serves as a further connecting means. When the reagent disk 200 drives the magnetic bead bottle 120 to rotate through the gear, the connection between the gear and the toothed ring 123 can be realized through the engagement of the gear.

As an alternative, the first engaging structure 121 and the second engaging structure 122 are located in a hollow cavity in the toothed ring 123. As shown in fig. 5, the first engaging structure 121 and the second engaging structure 122 are both located in the hollow cavity in the toothed ring 123, and the lengths of the first engaging structure 121 and the second engaging structure 122 extend out of the toothed ring 123. At this time, the toothed ring 123 may also be used as a protection structure to prevent the first engaging structure 121 and the second engaging structure 122 from being collided by an external object, thereby improving the safety of the first engaging structure 121 and the second engaging structure 122.
