[0044] Embodiment 1

[0045] like Figure 1 and Figure 2 As shown, this embodiment provides an analyzer reagent replenishing device 100, comprising: two reagent disks 110 arranged adjacent to each other, a sample loading chamber 120, two sample loading positions 122 and a moving component 130;

[0046] A plurality of reagent positions 111 are arranged on the reagent disk 110;

[0047] The sample loading chamber 120 is disposed above the reagent disk 110 , and a plurality of transfer positions 121 are disposed in the sample loading chamber 120 , wherein at least one transfer position 121 is a sampling position;

[0048] The two sample adding positions 122 are arranged side by side with the sampling position, and are respectively opposite to a target reagent position 111 on the two reagent disks 110;

[0049] The moving assembly 130 includes a transverse track 131, two vertical tracks 132, and two grabbing mechanisms 133 for grabbing the reagent bottle 200 on the transfer position 121. The two grabbing mechanisms 133 are respectively arranged on the two vertical tracks 132 and move along the vertical tracks 132. The two vertical tracks 132 are arranged on the transverse track 131 and move along the transverse track 131.

[0050] The transverse track 131 extends along the arrangement direction of the sampling positions and the sample loading positions 122 , and the transverse track 131 passes through the sampling positions and the sample loading positions 122 .

[0051] The reagent tray 110 is used to hold the reagent bottles 200 for testing. Usually, the reagent tray 110 is set in a disc shape so that when the reagent tray 110 rotates around its axis, it will not affect the equipment or structure outside the reagent tray 110. A plurality of reagent positions 111 are arranged circumferentially on the reagent tray 110, and one reagent bottle 200 can be placed in each reagent position 111.

[0052] The sample loading chamber 120 is used to place the supplementary reagent bottle 200, which can be added to the empty position on the reagent disk 110 or replace the reagent bottle 200 on the reagent disk 110. A plurality of reagent transfer positions 121 are arranged in the sample loading chamber 120, and one reagent transfer position 121 is correspondingly placed with one supplementary reagent bottle 200. At least one transfer position 121 is a sampling position, and the supplementary reagent at the sampling position can be taken away and placed on the reagent disk 110.

[0053] The sample loading chamber 120 is arranged above the reagent disk 110, and a sample loading position 122 is arranged side by side with the sampling position, and the sample loading position 122 is directly opposite to a target reagent position 111 on the reagent disk 110. The target reagent position 111 is the position on the reagent disk 110 where the supplementary reagent bottle 200 needs to be placed. As the reagent disk 110 rotates, the target reagent position 111 can correspond to different reagent positions 111, and the relative position between the target reagent position 111 and the sample loading chamber 120 is always fixed. One sample loading position 122 corresponds to one target reagent position 111.

[0054] The mobile assembly 130 is used for placing the supplementary reagent bottle 200 on the reagent tray 110. The mobile assembly 130 includes a transverse track 131, a vertical track 132 and a gripping mechanism 133, and the gripping mechanism 133 is used for grabbing or releasing the reagent bottle 200. When the gripping mechanism 133 clamps the reagent bottle 200, the reagent bottle 200 moves following the gripping mechanism 133. The gripping mechanism 133 is slidably connected with the vertical track 132, and slides vertically along the vertical track 132. The vertical track 132 is slidably connected with the transverse track 131, and slides horizontally along the transverse track 131. The gripping mechanism 133 can drive the reagent bottle 200 to move in both the transverse and vertical directions. The gripping mechanism 133 can specifically be a clamping claw, a suction cup, etc.

[0055] The extension direction of the transverse track 131 is consistent with the arrangement direction of the sampling position and the sample adding position 122 , and the transverse track 131 passes through the sampling position and the sample adding position 122 to ensure that the grabbing mechanism 133 can pass through the sampling position and the sample adding position 122 .

[0056] When in use, the grabbing mechanism 133 grabs the supplementary reagent bottle 200 at the sampling position, moves along the vertical track 132, and takes the supplementary reagent bottle 200 out of the sampling position. Then the vertical track 132 moves along the horizontal track 131, driving the grabbing mechanism 133 to move to the sample adding position 122. Then the grabbing mechanism 133 moves along the vertical track 132 to place the supplementary reagent bottle 200 at the target reagent position 111 on the reagent disk 110, thereby completing the replenishment of the reagent bottle 200.

[0057] Two reagent trays 110 are arranged adjacent to each other, and two grabbing mechanisms 133 respectively replenish the reagent bottles 200 for the two reagent trays 110. One grabbing mechanism 133 may replenish the reagent bottles 200 for one reagent tray 110, and the running path of the vertical track 132 is simple, which is convenient for planning the running path of the vertical track 132; or two grabbing mechanisms 133 may replenish the reagent bottles 200 for any reagent tray 110, and when a plurality of reagent bottles 200 need to be replenished in one reagent tray 110, the two grabbing mechanisms 133 may replenish the reagent bottles 200 for the reagent tray 110 alternately, and the reagent bottle replenishment efficiency is higher.

[0058] In this embodiment, since two reagent trays 110 are arranged adjacent to each other, the capacity for placing the reagent bottle 200 is increased, and the sample loading chamber 120 is arranged above the reagent tray 110, the distance between the sample loading chamber 120 and the reagent tray 110 is short, which saves the time required for placing the reagent bottle 200, and the grasping mechanism 133 can complete the grasping and placement of the reagent bottle 200 by making horizontal and vertical movements under the limitation of the horizontal track 131 and the vertical track 132. It has a simple structure and a concise motion trajectory, which is conducive to reducing production costs, reducing equipment failure rates, and improving the efficiency of reagent replenishment.

[0059] Embodiment 2

[0060] like Figure 1 As shown, based on the first embodiment, a plurality of transfer positions 121 are arranged side by side in the sample loading chamber 120 .

[0061] The transfer positions 121 are arranged in sequence in the sample loading chamber 120 , and the directions of the supplementary reagent bottles 200 in each transfer position 121 are the same. The sample loading position 122 can be arranged adjacent to the sample loading chamber 120 , or can be arranged in the sample loading chamber 120 and placed between two adjacent transfer positions 121 .

[0062] When in use, the grabbing mechanism 133 moves along the arrangement direction of the transfer positions 121 , and the sampling position can be any transfer position 121 , and grabs the supplementary reagent bottle 200 on the target transfer position 121 .

[0063] Embodiment 3

[0064] On the basis of the first embodiment, the sample loading chamber 120 is disc-shaped, and a plurality of transfer positions 121 are arranged along the circumference of the sample loading chamber 120 .

[0065] The sample loading chamber 120 is in the shape of a disk and can rotate around the axis of the disk. The transfer position 121 is arranged along the circumference of the disk. The sampling position is a fixed position, and the transfer position 121 corresponding to the position is the sampling position. As the sample loading chamber 120 rotates, the sampling position can correspond to different transfer positions 121.

[0066] When in use, the grabbing mechanism 133 moves laterally between the sampling position and the sample adding position 122 , and the distance between the sampling position and the sample adding position 122 is fixed.

[0067] Embodiment 4

[0068] like Figure 1 As shown, based on the first embodiment, the sample loading chamber 120 is arranged at an upper position between two reagent disks 110 .

[0069] The sample loading chamber 120 is arranged above the two reagent disks 100 . One grabbing mechanism 133 corresponds to one reagent disk 110 . The grabbing mechanism 133 moves between the corresponding reagent disk 110 and the sample loading chamber 120 . The movement trajectories of the two grabbing mechanisms 133 do not overlap, so as to avoid collision between the two grabbing mechanisms 133 .

[0070] In one embodiment, the distances from the sample loading positions 122 corresponding to the two reagent trays 110 to the sample loading chamber 120 are equal, so as to improve the efficiency of replenishing the reagent bottles 100 to the two reagent trays 110 at the same time.

[0071] Embodiment 5

[0072] Based on the fourth embodiment, the two reagent disks 110 have the same specifications.

[0073] The specifications of the two reagent trays 110 are the same, which means that the sizes of the two reagent trays 110 and the settings of the reagent positions 111 are consistent. Setting a transverse track 131 can pass through the sample loading positions 122 corresponding to the two reagent trays 110 at the same time, which is helpful to optimize the structure.

[0074] Embodiment 6

[0075] like Figure 2As shown, based on the first embodiment, the grabbing mechanism 133 includes a slide seat 1331 slidably connected to the vertical rail 132 and a grabbing portion 1332 disposed on the slide seat;

[0076] The gripping portion 1332 is adapted to the outer contour of the body of the reagent bottle 200 .

[0077] One side of the slide 1331 is slidably connected to the vertical rail 132, and the other side is connected to the gripping portion 1332. The gripping portion 1332 is used to complete the gripping or releasing of the reagent bottle 200. The outer contour of the gripping portion 1332 is adapted to the body of the reagent bottle 200, so as to facilitate the clamping of the body of the reagent bottle 200. The bottle body is gripped to avoid contact with the bottle mouth of the reagent bottle 200 to avoid contamination of the reagent.

[0078] Embodiment 7

[0079] like Figure 2 As shown, based on the first embodiment, the vertical rail 132 includes a first sub-rail 1321 and a second sub-rail 1322, the first sub-rail 1321 is slidably connected to the second sub-rail 1322, the first sub-rail 1321 is slidably connected to the horizontal rail 131, and the second sub-rail 1322 is slidably connected to the grasping mechanism 133.

[0080] The first sub-rail 1321 is slidably connected to the second sub-rail 1322, and the first sub-rail 1321 and the second sub-rail 1322 can slide relative to each other. The second sub-rail 1322 is slidably connected to the grasping mechanism 133, and the grasping mechanism 133 can slide vertically along the second sub-rail 1322. The first sub-rail 1321 is slidably connected to the transverse rail 131, and the first sub-rail 1321 can move laterally along the transverse rail 131.

[0081] When the first sub-rail 1321 and the second sub-rail 1322 overlap, the total length of the vertical track 132 is the length of the longer track of the first sub-rail 1321 and the second sub-rail 1322. When the first sub-rail 1321 and the second sub-rail 1322 are pulled apart, the total length of the vertical track 132 is approximately the sum of the lengths of the first sub-rail 1321 and the second sub-rail 1322.

[0082] When the reagent bottle 200 is moved, the first sub-rail 1321 and the second sub-rail 1322 overlap, the total length of the vertical rail 132 is shorter, and the space required to reserve for the vertical rail 132 to move horizontally is smaller, which is conducive to saving space and reducing the volume of the entire analyzer.

[0083] In some embodiments, a sliding component may be further provided on the first sub-rail 1321 and the second sub-rail 1322 . The sliding component may specifically be a vertical slide rail or a vertical slide rail group.

[0086] The intermediate transfer position 121 is provided with a receiving groove 123 , the inner wall of which matches the outer wall of the reagent bottle 200 . The receiving groove 123 limits the placement direction of the reagent, making it easier for the grabbing mechanism 133 to grab the reagent bottle 200 .
