[0001] This application relates to the field of fluorescence immunoassay equipment, and particularly to a fully automatic fluorescence immunoassay device. Background Art

[0002] Immunochromatographic analysis is a membrane analysis method that combines the specific immune reaction of antigen-antibody and chromatographic technology. Fluorescence immunoassay is an analysis technique that uses fluorescent substances as tracers, labels antigens or antibodies to react with the analyte, and measures the fluorescence intensity of the final product to obtain the concentration of the analyte.

[0003] Fluorescence immunoassay equipment plays an important role in the field of modern medical testing. Its automated operation significantly improves the testing efficiency and accuracy. With the rapid development of medical technology, fluorescence immunoassay equipment has gradually become an indispensable tool in laboratories.

[0004] Currently, to achieve the automatic supply of reagent cards, a hook card mechanism is usually used to sequentially hook out multiple-layer reagent cards from the front end of the reagent card and pull the hooked-out reagent card into the slot of the incubation tray.

[0005] However, the above-mentioned reagent card supply method has the problems of too long moving stroke of the hook card mechanism, low supply efficiency, and easy jamming during the hook card process. Summary of the Invention

[0014] By adopting the above technical solutions, the automatic supply of reagent cards in the fully automatic fluorescence immunoassay device is realized. The specific effects are as follows:

[0015] 1. Through the design of the card bin base and the card slot, the reagent card bin can be stably placed, ensuring the reliability of the device operation;

[0016] 2. The X-direction driving unit and the Z-direction driving unit of the card pushing assembly cooperate to realize the card pushing action of the card pushing unit, so as to push one or more reagent cards out of the discharge port at one time, improving the operation efficiency;

[0017] 3. The design of the partition plate in the card pushing unit can effectively insert under the second reagent card, avoiding the second reagent card pressing on the first reagent card, and ensuring the accurate separation and transmission of the first reagent card.

[0018] Optionally, the number of the card slots is multiple, and the multiple card slots are arranged at intervals along the Y direction;

[0019] The card pushing assembly further includes a temporary storage block and a first Y-direction driving unit;

[0020] The temporary storage block has a temporary storage through slot;

[0021] The card pushing unit and the temporary storage block are arranged at intervals along the X direction, and both are connected to the first Y-direction driving unit; the first Y-direction driving unit is used to drive the card pushing unit and the temporary storage block to move along the Y direction, so that the card pushing assembly switches between a first state and a second state;

[0022] In the first state, the temporary storage through slot is communicated with the discharge port, and the card pushing unit is used to push the first reagent card into the temporary storage through slot;

[0023] In the second state, the temporary storage through slot is communicated with a preset station, and the card pushing unit is used to push the first reagent card in the temporary storage through slot into the preset station.

[0024] By adopting the above technical solutions, the fully automatic fluorescence immunoassay device can realize the management of reagent card bins with multiple card slots, and through the cooperation of the card pushing assembly and the temporary storage block, the flexibility and automation degree of reagent card transmission are improved. The specific effects are as follows:

[0025] 1. By setting a plurality of card slots arranged at intervals in the Y direction, the simultaneous placement of multiple reagent card bins is achieved, significantly improving the processing capacity of the device.

[0026] 2. The introduction of the temporary storage block and its temporary storage through slots provide a temporary storage space for the reagent cards, facilitating orderly transfer between different workstations. Especially when there are multiple reagent cards in the temporary storage through slots, the temporary storage through slots can prevent the stacked reagent cards from shifting or toppling.

[0027] 3. The first Y-direction driving unit drives the card pushing unit and the temporary storage block to move in the Y direction, so that the card pushing unit and the temporary storage block can act on the selected reagent card bin; the card pushing assembly can switch between the first state and the second state, thereby realizing the precise transfer of the reagent card from the inside of the box body to the temporary storage through slot and then to the preset workstation.

[0028] Optionally, the fully automatic fluorescence immunoassay device further includes an information identification member and a scanning assembly;

[0029] The information identification member is arranged on the box body;

[0030] The scanning assembly includes a scanning member and a second Y-direction driving unit, and the second Y-direction driving unit is connected to the scanning member and is used to drive the scanning member to move in the Y direction;

[0031] The scanning member is used to scan the information identification member.

[0032] By adopting the above technical solutions, the fully automatic fluorescence immunoassay device can realize automatic scanning and identification of the information identification of the reagent card bin. The specific effects are as follows:

[0033] By arranging the information identification member on the box body and combining the scanning member and the second Y-direction driving unit in the scanning assembly, the scanning member can move in the Y direction to accurately scan the information identification member, thereby realizing the rapid identification and recording of the reagent card information in the reagent card bin.

[0034] This solution improves the automation degree of the device, reduces the need for manual operation, and improves work efficiency and accuracy.

[0035] Optionally, a second through slot is arranged at the bottom of the card bin base along the Y direction;

[0036] One end of the first through slot extends to the edge of the card bin base, and the other end is communicated with the second through slot;

[0037] One end of the second through slot extends to one side edge of the card bin base, so that the card pushing unit can enter the second through slot.

[0038] By adopting the above technical solution, one end of the second through groove extends to one side edge of the cartridge base, enabling the card pushing unit to enter each card slot of the cartridge base through the second through groove, so as to realize the precise pushing operation of the reagent card subsequently. The communication design of the first through groove and the second through groove ensures the flexible movement of the card pushing unit between different positions, thereby enabling the reagent cards in different reagent cartridges to be pushed out, improving the automation degree and operation efficiency of the equipment.

[0039] One end of the first through groove extends to one side edge of the cartridge base, facilitating the card pushing unit to disengage from the cartridge base and push out the reagent card.

[0040] The other end of the first through groove and the other end of the second through groove do not extend to the edge of the cartridge base, which helps to improve the structural strength of the cartridge base.

[0041] Optionally, a limiting protrusion is provided in the card slot, and a first limiting groove for limiting cooperation with the limiting protrusion is provided at the bottom of the reagent cartridge.

[0042] The fully automatic fluorescence immunoassay device further includes a travel switch, and the travel switch is arranged above one side of the card slot.

[0043] By adopting the above technical solution, the reagent cartridge can be accurately positioned through the cooperation of the limiting protrusion and the first limiting groove, avoiding shaking or offset of the reagent cartridge in the card slot, thereby improving the stability of the equipment. At the same time, the setting of the travel switch can detect whether the reagent cartridge is correctly placed in the card slot, ensuring the reliability of the equipment during operation and preventing operation errors caused by improper placement of the reagent cartridge.

[0044] Optionally, the card pushing unit further includes a roller, and the roller is arranged below the partition plate and rotatably connected to the mounting block;

[0045] An opening is provided on the partition plate, a part of the roller passes through the opening and is located above the opening, and the roller is used for rolling contact with the reagent card.

[0046] By adopting the above technical solution, the setting of the roller can reduce the friction between the card pushing unit and the reagent card, making the card pushing process smoother and improving the accuracy and reliability of card pushing.

[0047] Optionally, the first reagent card includes at most n of the reagent cards;

[0048] The reagent card has a second limiting groove, and the box body has a limiting part for limiting cooperation with the second limiting groove, and the limiting part is used for limiting the reagent cards other than the n reagent cards from bottom to top.

[0049] By adopting the above technical solutions, precise limiting and batch management of reagent cards can be achieved. Specifically, by setting the limiting structure, only up to n reagent cards can be pushed by the card-pushing assembly from bottom to top, and the remaining reagent cards are fixed by the limiting part, thus avoiding the phenomenon of dislocation during the card-pushing process and improving the stability and reliability of the equipment operation.

[0050] Optionally, when the number of reagent cards included in the first reagent card is less than n, the roller can drive the second reagent card to move upward during the process of entering below the second reagent card, so that all the reagent cards included in the second reagent card are in limiting cooperation with the limiting part.

[0051] By adopting the above technical solutions, when the number of reagent cards included in the first reagent card is less than n, the roller can drive the second reagent card to move upward during the process of entering below the second reagent card, so that all the reagent cards included in the second reagent card are in limiting cooperation with the limiting part. This design ensures the stability and accuracy of the reagent cards in the stacked state, effectively prevents the reagent cards from being misaligned during the card-pushing process, and improves the reliability of the automated operation of the equipment.

[0052] Optionally, the reagent card bin has a material blocking unit, and the material blocking unit includes a baffle and a resetting member;

[0053] The baffle is arranged at the discharge port and is hinged to the bin base, and the baffle is used to block the discharge port;

[0054] The resetting member is connected to the baffle and is used to reset the baffle.

[0055] By adopting the above technical solutions, the material blocking unit can effectively prevent the reagent cards from accidentally sliding out of the discharge port in the non-working state, and improves the reliability of the equipment. Among them, the baffle is arranged at the discharge port and is hinged to the bin base, and can be opened when needed to allow the reagent cards to be pushed out, and block the discharge port when not needed to prevent the reagent cards from falling off under the influence of external force. The resetting member is connected to the baffle to ensure that the baffle automatically resets after the reagent cards are pushed, keeping the discharge port closed, thereby improving the stability and safety of the equipment.

[0056] In summary, the present application includes at least one of the following beneficial technical effects:

[0057] 1. Through the cooperation of the card-pushing unit and the partition plate in the card-pushing assembly, single or multiple reagent cards can be precisely separated and pushed, and then the supply efficiency of the reagent cards can be changed according to actual needs, significantly improving the stability of the equipment operation and the detection efficiency;

[0058] 2. The setting of the rollers can prevent the reagent card from being scratched, and the rollers and the partition plate can lift the reagent cards that have not been pushed out yet, so that the reagent cards that have not been pushed out yet are limited by the limiting part, preventing the reagent cards that have not been pushed out from moving along with the pushed-out reagent cards;

[0059] 3. The design of the cartridge base and the reagent card cartridge in combination with the specific structure of the card pushing assembly solves the problems of easy jamming or scratching of the reagent card in the prior art when dealing with multi-layer reagent cards, and optimizes the overall feeding process.

[0076] The following further elaborates on this application in conjunction with the attached Figures 1 to 10 for a more detailed description of this application

[0077] Embodiment 1

[0078] As Figures 1 to 7 shown, the embodiment of this application discloses a fully automatic fluorescence immunoassay device, including a card bin base 1, a reagent card bin 2, a card pushing assembly 3, a scanning assembly 4, a travel switch 5, and an incubation tray 6

[0079] A plurality of card slots 11 are evenly spaced along the Y-direction on the card bin base 1. The card slots 11 are used to place the reagent card bin 2. The specifications and types of the reagent card bins 2 placed in different card slots 11 can be the same or different

[0080] A limiting protrusion 12 is provided on the bottom wall of the card slot 11. The limiting protrusion 12 can be strip-shaped and is arranged along the X-direction. A first limiting groove 211 is provided at the bottom of the reagent card bin 2. When the reagent card bin 2 is placed in the card slot 11, the limiting protrusion 12 is in limiting cooperation with the first limiting groove 211, thereby preventing the reagent card bin 2 from shaking

[0081] The travel switch 5 is arranged on the card bin base 1 and is located above one side of the card slot 11 along the X-direction. When the reagent card bin 2 is stably placed in the corresponding card slot 11, the reagent card bin 2 can contact the travel switch 5. Therefore, the travel switch 5 can detect whether the reagent card bin 2 is placed in place

[0082] The reagent card bin 2 includes a box body 21, a drying box 22, a magnet, an information identification member, a material blocking unit 23, and a plurality of reagent cards 24. The drying box 22, the magnet, and the plurality of reagent cards 24 are all located inside the box body 21.

[0083] Among them, both the drying box 22 and the magnet are fixed to the inner wall of the box body 21. A desiccant is installed inside the drying box 22, so as to keep the inside of the reagent card bin 2 dry. The desiccant can specifically be a silica gel desiccant. The magnet can be adsorbed to the card bin base 1 to further fix the reagent card bin 2.

[0084] The plurality of reagent cards 24 are placed inside the box body 21 in a stacked form.

[0085] At the bottom of the two opposite ends of the box body 21 along the X direction, a pushing notch 212 and a discharging port 213 are respectively provided.

[0086] The card pushing assembly 3 includes a card pushing unit 31, a temporary storage block 32, an X-direction driving unit 33, and a first Y-direction driving unit 34.

[0087] The first Y-direction driving unit 34 includes a first mounting seat, a second mounting seat 341, a first Y-direction guide rail 342, and a first belt drive module 343. The first Y-direction guide rail 342 and the first belt drive module 343 are both arranged on the first mounting seat. The second mounting seat 341 is slidably arranged on the first Y-direction guide rail 342.

[0088] The first belt drive module 343 may include a motor, a belt, and two belt pulleys. The belt pulley is rotatably connected to the first mounting seat; the two belt pulleys are connected by a belt drive; the motor is drivingly connected to one of the belt pulleys; the second mounting seat 341 is connected to the belt. By driving the belt pulley to rotate with the motor, the second mounting seat 341 can be made to slide along the first Y-direction guide rail 342.

[0089] The X-direction driving unit 33 is arranged on the second mounting seat 341. The X-direction driving unit 33 includes an X-direction guide rail and a second belt drive module. The card pushing unit 31 is slidably arranged on the X-direction guide rail; the structure of the second belt drive module can be designed with reference to the first belt drive module 343. The belt of the second belt drive module is connected to the card pushing unit 31.

[0090] Specifically, the card pushing unit 31 includes a mounting block 311 and a card pushing member 312. The mounting block 311 is slidably arranged on the X-direction guide rail, and the mounting block 311 is connected to the belt of the second belt drive module. The card pushing member 312 is arranged on the mounting block 311.

[0091] A first through slot 13 is provided along the X direction at the bottom of the card slot 11. A second through slot 14 is provided along the Y direction at the bottom of the card bin base 1. One end of the first through slot 13 extends to the edge on the side of the card bin base 1 where the discharge port 213 is located, and the other end communicates with the second through slot 14. One end of the second through slot 14 extends to one side edge of the card bin base 1 so that the card pushing unit 31 can enter the second through slot 14.

[0092] The card pushing unit 31 and the temporary storage block 32 are arranged at intervals along the X direction, and a temporary storage through slot is provided on the temporary storage block 32. When it is necessary to push out the reagent card 24 in the reagent card bin 2, the first Y-direction driving unit 34 can drive the second mounting seat 341 to move along the Y direction, so that the card pushing unit 31 and the temporary storage block 32 respectively reach opposite sides of one of the reagent card bins 2, completing the preparation work for card pushing. At this time, the card pushing assembly 3 is in the first state, the temporary storage through slot communicates with the discharge port 213 of the corresponding reagent card bin 2, and the card pushing unit 31 is located in the second through slot 14.

[0093] After that, the X-direction driving unit 33 can drive the card pushing unit 31 to move along the X direction, so that the card pushing unit 31 enters the first through slot 13, and enters the box body 21 from the pushing notch 212, pushing out the lowermost reagent card 24 from the discharge port 213 until the lowermost reagent card 24 enters the temporary storage through slot of the temporary storage block 32.

[0094] Then, the first Y-direction driving unit 34 drives the card pushing unit 31 and the temporary storage block 32 to move together until the temporary storage through slot communicates with the preset station. At this time, the card pushing assembly 3 is in the second state. In the second state, the X-direction driving unit 33 can drive the card pushing unit 31 to move, so as to push the reagent card 24 in the temporary storage through slot into the preset station, completing the supply of the reagent card 24. Among them, a plurality of slots for placing the reagent card 24 are provided at intervals along the circumferential direction on the incubation tray 6, and the incubation tray 6 can be rotated so that each slot reaches the preset station in turn. The incubation tray 6 is a conventional technology and will not be elaborated here.

[0095] The material blocking unit 23 includes a baffle 231 and a reset member 232.

[0096] The baffle 231 is arranged at the discharge port 213 and is hinged to the card bin base 1. The reset member 232 is connected to the baffle 231 and is used to reset the baffle 231. Among them, the reset member 232 can be a snap spring. When the card pushing assembly 3 pushes the reagent card 24 to move, it can squeeze the baffle 231 to open the discharge port 213, and at this time the snap spring is in a deformed state. When the reagent card 24 is completely pushed out, the baffle 231 is reset under the action of the snap spring, thereby preventing the reagent card 24 in the box body 21 from being discharged.

[0097] The information identification member is arranged on the outer wall of the box body 21, and the information identification member can be an NFC chip.

[0098] The scanning assembly 4 includes a scanning member 41 and a second Y-direction driving unit 42. The second Y-direction driving unit 42 is connected to the scanning member 41 and is used to drive the scanning member 41 to move along the Y direction, so that the scanning member 41 can scan the information identification members on each reagent cartridge 2, and complete the information recognition of different reagent cartridges 2. Among them, the scanning member 41 is an NFC chip scanner. The second Y-direction driving unit 42 includes a bracket, a second Y-direction guide rail, and a third belt drive module. The second Y-direction guide rail and the third belt drive module are both arranged on the bracket. The scanning member 41 is slidably arranged on the second Y-direction guide rail; the structure of the third belt drive module can be designed with reference to the first belt drive module 343. The scanning member 41 is driven to slide along the second Y-direction guide rail by the third belt drive module.

[0099] Embodiment 2

[0100] The difference between the embodiment of the present application and Embodiment 1 is that the card pushing assembly 3 is improved.

[0101] Specifically, as Figure 1 , Figure 2 , Figures 8 to 10 shown, the card pushing assembly 3 further includes a Z-direction driving unit 35. The Z-direction driving unit 35 includes a third mounting seat 351, a Z-direction guide rail 352, and a fourth belt drive module 353. The third mounting seat 351 is slidably arranged on the X-direction guide rail and is connected to the belt of the second belt drive module. The Z-direction guide rail 352 and the fourth belt drive module 353 are both arranged on the third mounting seat 351; the mounting block 311 of the card pushing unit 31 is slidably arranged on the Z-direction guide rail 352; the mounting block 311 is connected to the fourth belt drive module 353. The structure of the fourth belt drive module 353 can be designed with reference to the first belt drive module 343, and the card pushing unit 31 can be driven to move along the Z direction by the fourth belt drive module 353.

[0102] The X direction, the Y direction, and the Z direction are perpendicular to each other, where the Z direction can be the vertical direction, and the X direction and the Y direction are horizontal directions.

[0103] By driving the card pushing unit 31 to lift and lower through the Z-direction driving unit 35, the card pushing unit 31 can push out multiple reagent cards 24 at one time, improving the card pushing efficiency.

[0104] The card pushing unit 31 further includes a partition plate 313 and rollers 314. The partition plate 313 is located above the card pushing member 312. The rollers 314 are arranged below the partition plate 313 and are rotatably connected to the mounting block 311. An opening is provided on the partition plate 313, and a part of the roller 314 passes through the opening and is located above the opening.

[0105] When pushing the card, the X-direction driving unit 33 drives the card-pushing unit 31 to move in the X direction. The partition plate 313 can be inserted between the first reagent card and the second reagent card, so that the first reagent card is separated from the second reagent card. Then, the card-pushing member 312 contacts the first reagent card and pushes the first reagent card to move, and the roller 314 moves to the lower side of the second reagent card. When the card-pushing unit 31 is pushing the card, the roller 314 is in rolling contact with the second reagent card, thus avoiding scratching the reagent card 24. Among them, the first reagent card includes at least one reagent card 24 from bottom to top; the second reagent card includes other reagent cards 24 except the first reagent card. The thickness of the partition plate 313 is relatively thin, so it is easier to insert between the first reagent card and the second reagent card.

[0106] After that, as the card-pushing unit 31 moves, the card-pushing member 312 pushes the first reagent card out of the discharge port 213.

[0107] In the second state, the card-pushing member 312 pushes the first reagent card into the preset station. When the first reagent card includes multiple reagent cards 24, the card-pushing member 312 only pushes the lowermost reagent card 24 in the temporary storage through groove into the slot at the preset station each time. Through multiple card-pushing operations, all the reagent cards 24 in the temporary storage through groove are sequentially pushed into the respective slots of the incubation tray 6.

[0108] The first reagent card includes at most n reagent cards 24. The reagent card 24 has a second limiting groove 241, and the box body 21 has a limiting portion 214 that is in limiting cooperation with the second limiting groove 241. The limiting portion 214 can be a vertically arranged strip-shaped protrusion. The limiting portion 214 is used to limit the reagent cards 24 other than the n reagent cards 24 from bottom to top.

[0109] For example, n can be equal to 2. That is, the card-pushing unit 31 can push out at most two reagent cards 24 from the box body 21 each time. The limiting portion 214 can limit the reagent cards 24 other than the lowermost two reagent cards 24, so as to prevent the other reagent cards 24 from shifting or tilting during the process of the card-pushing unit 31 pushing the two reagent cards 24 to move.

[0110] Furthermore, when the number of reagent cards 24 included in the first reagent card is less than n, the roller 314 can drive the second reagent card to move upward during the process of entering the lower side of the second reagent card, so that all the reagent cards 24 included in the second reagent card are in limiting cooperation with the limiting portion 214.

[0111] For example, when n is equal to 2, the card pushing unit 31 can push out one or two reagent cards 24 each time. If the card pushing unit 31 only pushes out one reagent card 24 each time, before pushing the card, the top height of the roller 314 is higher than the top height of the lowermost reagent card 24, so that when the roller 314 enters below the second reagent card 24 from bottom to top, it can lift the other reagent cards 24 except the lowermost reagent card 24, so that the other reagent cards 24 except the lowermost reagent card 24 are mutually limited by the limiting part 214. Even if only one reagent card 24 is pushed out each time, the other reagent cards 24 will not shift.

[0112] In addition, a sliding block 315 can be slidably arranged on the mounting block 311, and the roller 314 is rotatably arranged on the sliding block 315. A driving member (not shown) connected to the sliding block 315 is arranged on the mounting block 311. By driving the sliding block 315 to lift and lower through the driving member, the height of the sliding block 315 can be changed, and further the lifting height of the second reagent card can be changed.
