[0045] Embodiment 1

[0046] like Figure 1 As shown, this embodiment provides an analyzer reagent replenishing device 100, including: a reagent disk 110, a sample loading chamber 120, a sample loading position 122 and a moving component 130;

[0047] A plurality of reagent positions 113 are arranged on the reagent disk 110;

[0048] 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;

[0049] The sample adding position 122 is arranged side by side with the sampling position and is directly opposite to a target reagent position 113 on the reagent disk 110;

[0050] See also Figure 2The moving assembly 130 includes a transverse track 131, a vertical track 132, and a grabbing mechanism 133 for grabbing the reagent bottle 200 on the transfer position 121, the grabbing mechanism 133 is arranged on the vertical track 132 and moves along the vertical track 132, and the vertical track 132 is arranged on the transverse track 131 and moves along the transverse track 131;

[0051] 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 .

[0052] 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 113 are arranged circumferentially on the reagent tray 110, and one reagent bottle 200 can be placed in each reagent position 113.

[0053] 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.

[0054] 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 113 on the reagent disk 110. The target reagent position 113 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 113 can correspond to different reagent positions 113, and the relative position of the target reagent position 113 and the sample loading chamber 120 is always fixed. One sample loading position 122 corresponds to one target reagent position 113.

[0055] 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.

[0056] 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 .

[0057] 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 113 on the reagent disk 110, thereby completing the replenishment of the reagent bottle 200.

[0058] In this embodiment, since the sample loading bin 120 is arranged above the reagent tray 110, the distance between the sample loading bin 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 performing horizontal and vertical movements under the limitation of the horizontal track 131 and the vertical track 132. The structure is simple and the movement trajectory is concise, which is conducive to reducing production costs, reducing equipment failure rate, and improving the efficiency of reagent replenishment.

[0059] Embodiment 2

[0060] 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] Based on the first embodiment, the reagent disk 110 includes a first reagent disk 111 and a second reagent disk 112 arranged side by side;

[0069] The sample loading position 122 includes a first sample loading position corresponding to the first reagent disk 111 and a second sample loading position corresponding to the second reagent disk 112 .

[0070] The reagent tray 110 includes a first reagent tray 111 and a second reagent tray 112, which are arranged adjacent to each other. The first reagent tray 111 and the second reagent tray 112 are both used to hold reagent bottles 200 for detection, and the two reagent trays 110 can hold more reagent bottles 200.

[0071] The sample adding position 122 includes a first sample adding position and a second sample adding position. The first sample adding position corresponds to the first reagent disk 111 and is used to supplement the first reagent disk 111 with reagents. The second sample adding position corresponds to the second reagent disk 112 and is used to supplement the second reagent disk 112 with reagents.

[0072] The reagent replenishment of the first reagent disk 111 and the reagent replenishment of the second reagent disk 112 may be actually replenished by a common set of moving components 130, or may partially share a set of moving components 130, or may be actually replenished by using respective corresponding moving components 130.

[0073] Embodiment 5

[0074] Based on the fourth embodiment, the first reagent disk 111 and the second reagent disk 112 have the same specifications.

[0075] The first reagent tray 111 and the second reagent tray 112 have the same specifications, which means that the sizes of the first reagent tray 111 and the second reagent tray 112 and the settings of the reagent positions 113 are consistent. Setting a transverse track 131 can simultaneously pass through the sample addition positions 122 corresponding to the first reagent tray 111 and the second reagent tray 112, respectively, which helps to optimize the structure.

[0076] Embodiment 6

[0077] On the basis of 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;

[0078] The gripping portion 1332 is adapted to the outer contour of the body of the reagent bottle 200 .

[0079] 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.

[0080] Embodiment 7

[0081] 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 transverse rail 131 , and the second sub-rail 1322 is slidably connected to the gripping mechanism 133 .

[0082] 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.

[0083] 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.

[0084] 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.

[0085] In some embodiments, a sliding component may be provided between the first sub-rail 1321 and the second sub-rail 1322 . The sliding component may be a vertical slide rail or a vertical slide rail group.

[0086] In some embodiments, a synchronization structure is provided on the first sub-rail 1321, the second sub-rail 1322 and the grabbing mechanism 133, and the synchronization structure includes a first connection portion fixedly provided at the lower end of the first sub-rail 1321, a second connection portion fixedly provided on the grabbing mechanism 133, and a wheel belt assembly;

[0087] The wheel belt assembly includes a driven wheel, a wheel belt, and a driving wheel connected to the driving member;

[0088] The driving wheel is arranged at one end of the second sub-rail 1322, the driven wheel is arranged at the other end of the second sub-rail 1322, and the wheel belt is sleeved on the driving wheel and the driven wheel;

[0089] The first connection portion and the second connection portion are fixedly connected to the wheel belt respectively.

[0090] In this embodiment, the first-level second sub-rail 1322 is vertically slidably connected to the first sub-rail 1321, and the grabbing mechanism 133 is vertically slidably connected to the second sub-rail 1322. The driving wheel and the driven wheel are respectively arranged at both ends of the second sub-rail 1322, and belts are sleeved on the driving wheel and the driven wheel. Under the action of the belts, the driving wheel drives the driven wheel to rotate synchronously.

[0091] The belts sleeved on the driving wheel and the driven wheel have two opposite sides, and the belts on both sides move synchronously in opposite directions. When the belt on one side moves upward, the belt on the other side moves downward. A first connecting portion is provided at the lower end of the first sub-rail 1321, and the first connecting portion passes through the second sub-rail 1322 and is connected to the belt. The first connecting portion is fixedly connected to the belt on one side, and the second connecting portion is fixedly connected to the belt on the other side.

[0092] The first connection part is connected to the inner wheel belt, and the second connection part is connected to the outer wheel belt. When the driving wheel rotates clockwise, the inner wheel belt moves downward, driving the first connection part to move downward relative to the second sub-rail 1322, and the second sub-rail 1322 moves upward relative to the first sub-rail 1321. The outer wheel belt moves upward, driving the second connection part to move upward relative to the second sub-rail 1322. The position of the first sub-rail 1321 in the vertical direction cannot be changed. When the driving wheel rotates clockwise, the second sub-rail 1322 and the grabbing mechanism 133 move upward synchronously. Conversely, when the driving wheel rotates counterclockwise, the second sub-rail 1322 and the grabbing mechanism 133 move downward synchronously.

[0093] In this embodiment, the second sub-rail 1322 and the grabbing mechanism 133 move synchronously, and the telescopic efficiency of the lifting mechanism 100 is high.

[0094] Furthermore, the second sub-rail 1322 includes a bottom plate 1031 and a slide rail 1032 disposed on the bottom plate 1031 , and an avoidance groove 1033 is disposed on the bottom plate 1031 , so that the first connecting portion passes through the avoidance groove 1033 and is fixedly connected to the wheel belt.

[0095] An escape groove 1033 is provided on the bottom plate 1031, and the extension direction of the escape groove 1033 is consistent with the movement direction of the second sub-rail 1322 relative to the first sub-rail 1321. A slide rail 1032 is provided on one side of the bottom plate 1031, and the slide rail 1032 is adapted to the first sub-rail 1321, driving the bottom plate 1031 to slide vertically on the first sub-rail 1321. A driving wheel and a driven wheel are provided on the other side opposite to the one side where the slide rail 1032 is provided, and the driving wheel and the driven wheel are provided at both ends of the escape groove 1033. The first connecting portion passes through the escape groove 1033 and is connected to the wheel belt, and the first connecting portion can move along the escape groove 1033 and is not blocked on the movement path.

[0096] In some embodiments, position sensors for sensing the position of the second sub-rail 1322 are respectively disposed at the upper end and the lower end of the first sub-rail 1321 .

[0097] The position sensor is used to sense the position of the second sub-rail 1322 relative to the first sub-rail 1321, and send a signal to control the motor to stop, so as to prevent the parts from colliding or being damaged due to over-rotation of the motor. When the second sub-rail 1322 moves upward, it triggers the position sensor set at the upper end of the first sub-rail 1321, and the position sensor sends a signal to control the motor to stop, so as to prevent the second sub-rail 1322 from continuing to move upward. When the second sub-rail 1322 moves downward, it triggers the position sensor set at the lower end of the first sub-rail 1321, and the position sensor sends a signal to control the motor to stop, so as to prevent the second sub-rail 1322 from continuing to move downward.

[0098] In some embodiments, position sensors of the sensing grasping mechanism 133 are respectively disposed at the upper end and the lower end of the second sub-rail 1322 .

[0099] The position sensor is used to sense the position of the grabbing mechanism 133 relative to the second sub-rail 1322, and send a signal to control the motor to stop, so as to prevent the parts from colliding or being damaged due to over-rotation of the motor. When the grabbing mechanism 133 moves upward, the position sensor set at the upper end of the second sub-rail 1322 is triggered, and the position sensor sends a signal to control the motor to stop, so as to prevent the grabbing mechanism 133 from continuing to move upward. When the grabbing mechanism 133 moves downward, the position sensor set at the lower end of the second sub-rail 1322 is triggered, and the position sensor sends a signal to control the motor to stop, so as to prevent the grabbing mechanism 133 from continuing to move downward.

[0100] In some embodiments, the first sub-rail 1321 and the second sub-rail 1322 are of equal length.

[0101] The first sub-rail 1321 and the second sub-rail 1322 are of equal length. When the first sub-rail 1321 and the second sub-rail 1322 overlap, the length in the vertical direction is the shortest.

[0102] In Example 1, the first sub-rail 1321 is 6 cm, the second sub-rail 1322 is also 6 cm, and the length of the connecting portion when extended is 1 cm, so the total length when extended is 10 cm, and the total length when overlapped is 6 cm. In Example 2, the first sub-rail 1321 is 7 cm, the second sub-rail 1322 is also 5 cm, and the length of the connecting portion when extended is 1 cm, so the total length when extended is 10 cm, and the total length when overlapped is 7 cm.

[0103] According to Example 1 and Example 2, the total length when stretched is 10 cm, but the total length when overlapped is smaller in Example 1 than in Example 2. When the total length when stretched is constant, the first sub-rail 1321 and the second sub-rail 1322 are equal in length, and the length when overlapped is the shortest.

[0105] On the basis of the first embodiment, a receiving groove 123 for receiving the reagent bottle 200 is provided at the intermediate transfer position 121 , and the inner wall of the receiving groove 123 is matched with the outer wall of the reagent bottle 200 .

[0106] 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 .

[0107] Embodiment 9

[0108] On the basis of the first embodiment, a recovery chamber 140 is arranged on one side outside the sample loading chamber 120, and a plurality of recovery positions 141 are arranged in the recovery chamber 140, and the recovery positions 141 are arranged side by side with the sampling position and the sample loading position 122;

[0109] Also, the transverse track 131 passes through the recovery bin 140 .

[0110] The recovery bin 140 is used to recover the empty reagent bottles 200 or misplaced reagent bottles 200 on the reagent tray 110, freeing up the reagent positions 113, so as to facilitate the replenishment of the reagent bottles 200 in the reagent bin to the reagent tray 110. The recovery bin is arranged on one side outside the sample loading bin 120, and the transverse track 131 extends through the recovery bin 140. A plurality of recovery positions 141 are arranged in the recovery bin 140, and one recovery position 141 can be corresponding to place a reagent bottle 200 recovered from the reagent tray 110.

[0111] The recycling of the reagent bottle 200 can be completed solely or partially by the moving component 130, or a separate component for recycling can be provided.

[0112] In some embodiments, the recovery bin 140 further includes a pull-out tray, and the recovery position 141 is disposed on the pull-out tray;

[0113] The pull-out tray is slidably connected to the base.

[0114] The recovery position 141 is set on a pull-out tray, which is slidably connected to a base. The base is fixedly set on the analyzer. The pull-out tray can slide relative to the base and be pulled out of the base to facilitate taking out the reagent bottle placed on the recovery position 141.

[0115] Specifically, the pull-out tray and the base may be slidably connected by providing a sliding device (such as a slide rail, a pulley, etc.), or the pull-out tray and the base may be in direct contact to cause frictional sliding.

[0116] Furthermore, a handle is provided on the pull-out tray, and the gripping direction of the handle is consistent with the sliding direction of the pull-out tray, so that the pull-out tray can be pulled out by hand. The specific handle can be a recessed or protruding handle, which is not limited here.

[0117] Furthermore, a first positioning component is provided on the pull-out tray;

[0118] A second positioning component is arranged on the base;

[0119] When the drawer tray is installed in place on the base, the first positioning component and the second positioning component form a constrained connection.

[0120] Constrained connection refers to the mutually constrained and limited connection relationship between objects. When the constrained connection is established, the relative position relationship between the objects will not change without external interference. After the constraint connection is released, the relative position relationship can change. For example, when the buckle is buckled into the buckle, the constraint connection between the buckle and the buckle is established; for another example, when the positive and negative poles of a magnet are attracted together, the constraint connection between the positive and negative poles is established.

[0121] Since the path for grabbing and placing the grabbing assembly 130 is preset, if the pull-out tray and the base are not installed in place, the grabbing assembly 130 will not be able to accurately place the reagent bottle on the recovery position 141, which may cause the reagent bottle to fall over. The first in-place assembly is set on the pull-out tray, and the second in-place assembly is set on the base. When the first in-place assembly and the second in-place assembly form a constraint connection, it means that the pull-out tray is installed in place on the base, and the placement position of the grabbing assembly 130 for placing the reagent bottle is aligned with the recovery position 141. At the same time, after the constraint connection is established, there is no relative displacement between the pull-out tray and the base.

[0122] In one embodiment, a sensing device is provided on the first positioning component and / or the second positioning component. When the constraint connection between the first positioning component and the second positioning component is disconnected, the sensing device sends a signal to control the analyzer to be unable to start up.

[0123] In one embodiment, the first component in place is a first magnetic component, and the second component in place is a second magnetic component that magnetically cooperates with the first magnetic component.

[0124] The first magnetic component is arranged on the pull-out tray, the second magnetic component is arranged on the base, and the first magnetic component and the second magnetic component are arranged opposite to each other, and the magnetic poles of the first magnetic component and the second magnetic component are opposite to each other. Specifically, when the first magnetic component and the second magnetic component are attracted together, the pull-out tray is installed in place on the base; or a limit block is arranged on the base, and the first magnetic component approaches the second magnetic component under the action of magnetic force until it is blocked by the limit block, and the pull-out tray is installed in place on the base.

[0125] In one embodiment, the first positioning component and the second positioning component are buckles and buckles for each other.

[0126] The buckle (buckle head) is set on the pull-out tray, and the buckle head (buckle) is set on the base. The buckle (buckle head) and the buckle head (buckle) are arranged opposite to each other on both sides of the buckling direction. The buckle (buckle head) moves closer to or away from the buckle head (buckle) following the movement of the pull-out tray. When the buckle and the buckle head are buckled, the pull-out tray is installed in place on the base.

[0127] In other embodiments, an anti-escape structure is provided on the base to prevent the pull-out tray from falling out.

[0128] The pull-out tray is slidably connected to the base, and an anti-slip structure is provided on the base to prevent the pull-out tray from being completely separated from the base, and to prevent the pull-out tray from tipping over due to the pull-out tray suddenly slipping out of the base. Specifically, the anti-slip mechanism can be a limit convex, a magnetic suction mechanism, a limit pull rope, or other common anti-slip structures.

[0129] In some embodiments, a receiving groove for receiving a reagent bottle is provided at the recovery position 141 , and an inner wall of the receiving groove is matched with an outer wall of the reagent bottle.

[0130] The receiving groove is matched with the outer wall of the reagent bottle, and the reagent bottle is placed in the receiving groove more stably, less likely to shake, and less likely to tip over.

[0131] Furthermore, the receiving slot is detachably connected to the drawer tray, so that the receiving slot on the drawer tray can be easily maintained or replaced.

[0132] Embodiment 10

[0133] On the basis of the first embodiment, the analyzer reagent replenishing device 100 further includes a sample delivery device 150 and a sample injection chamber 160;

[0134] The sample delivery device 150 includes a sample delivery trolley 151 , which moves between the sample input chamber 160 and the sample loading chamber 120 .

[0135] The sample injection chamber 160 is used to place the reagent bottle 200 that needs to be added to the reagent disk 110. The reagent bottle 200 is placed in the sample injection chamber 160, which is usually done manually.

[0136] The sample delivery device 150 is used to deliver the reagent bottle 200 to the reagent chamber. The sample delivery trolley 151 moves between the sample input chamber 160 and the sample loading chamber 120 , and the reagent bottle 200 is transported by the sample delivery trolley 151 .

[0137] Embodiment 11

[0138] On the basis of the tenth embodiment, the sample delivery device 150 further includes a pushing structure 152, and the pushing structure 152 includes a rotating motor, a rocker arm, a roller, a slider and a limiting track;

[0139] The output end of the rotating motor is connected to one end of the rocker arm, and the other end of the rocker arm is connected to the roller;

[0140] A limit groove is arranged on the slider, and the roller is arranged in the limit groove. The force of the roller acting on the inner wall of the limit groove has a component force that is consistent with the extension direction of the limit track;

[0141] The slider is slidably connected to the limiting track.

[0142] The motor drives the rocker arm to rotate, and the roller on the rocker arm slides in the limit groove on the slider. Due to the action of the limit track, the slider can only move along the limit track. The component force used by the roller on the inner wall of the limit groove that is perpendicular to the extension direction of the limit track is offset by the limit track, while the component force of the roller on the inner wall of the limit groove that is consistent with the extension direction of the limit track drives the slider to move.

[0143] Compared with common linear motion driving mechanisms such as worm gears or linear motors, the pushing structure 152 is more compact, has lower processing precision requirements, and has lower manufacturing costs.

[0144] Embodiment 12

[0149] The tray cover is disposed on the reagent tray 110 , so that a closed space is formed in the reagent tray 110 . Since the reagent bottles 200 on the reagent tray 110 are all in an open state, the reagents in the reagent bottles 200 can be effectively prevented from being contaminated by the outside world.

[0150] The opening and closing device cooperates with the moving assembly 130 to close or open the opening, so as to facilitate the replenishment of the reagent bottle 200 into the reagent disk 110 .
