[0026] Optionally, when the number of reagent cards contained in the first reagent card is less than n, the roller can drive the second reagent card to move upward and make all the reagent cards contained in the second reagent card cooperate with the limiting portion when entering below the second reagent card.

It can be opened when necessary to allow the reagent card to be pushed out, and the discharge port is blocked when not needed to prevent the reagent card from falling off due to external forces. The reset member is connected to the baffle to ensure that the baffle automatically resets after the reagent card is pushed out, keeping the discharge port closed, thereby improving the stability and safety of the device.

[0042] The following is combined with Figures 1 to 10 This application is described in further detail.

[0043] Example 1

[0044] like Figures 1 to 7 As shown, an embodiment of the present application discloses a fully automatic fluorescent immunoassay device, including a card compartment base 1, a reagent card compartment 2, a card pushing component 3, a scanning component 4, a travel switch 5 and an incubation tray 6.

[0045] A plurality of card slots 11 are evenly spaced along the Y direction on the card slot base 1 , and the card slots 11 are used to place the reagent card slots 2 . The specifications and types of the reagent card slots 2 placed in different card slots 11 may be the same or different.

[0046] A limiting protrusion 12 is provided on the bottom wall of the card slot 11. The limiting protrusion 12 may be in a long strip shape and is arranged along the X direction. A first limiting groove 211 is provided at the bottom of the reagent card compartment 2. When the reagent card compartment 2 is placed in the card slot 11, the limiting protrusion 12 is limited and matched with the first limiting groove 211, thereby preventing the reagent card compartment 2 from shaking.

[0047] The travel switch 5 is arranged on the card compartment base 1, and the travel switch 5 is located above one side of the card slot 11 along the X direction. When the reagent card compartment 2 is firmly placed in the corresponding card slot 11, the reagent card compartment 2 can contact the travel switch 5. Therefore, the travel switch 5 can detect whether the reagent card compartment 2 is placed in place.

[0048] The reagent card compartment 2 comprises a box body 21, a drying box 22, a magnet, an information identification piece, 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 in the box body 21.

[0049] The drying box 22 and the magnet are both fixed on the inner wall of the box body 21. The drying box 22 is filled with a desiccant to keep the reagent card compartment 2 dry. The desiccant can be a silica gel desiccant. The magnet can be adsorbed with the card compartment base 1 to further fix the reagent card compartment 2.

[0050] A plurality of reagent cards 24 are placed in the box body 21 in a stacked manner.

[0051] A material pushing notch 212 and a material discharging port 213 are respectively provided at the bottom of the box body 21 at two opposite ends along the X direction.

[0052] 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 .

[0053] 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 transmission module 343. The first Y-direction guide rail 342 and the first belt transmission 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.

[0054] The first belt transmission module 343 may include a motor, a belt and two pulleys. The pulley is rotatably connected to the first mounting seat; the two pulleys are connected through belt transmission; the motor is connected to one of the pulleys; and the second mounting seat 341 is connected to the belt. By driving the pulley to rotate, the second mounting seat 341 can slide along the first Y-direction guide rail 342.

[0055] The X-direction drive unit 33 is disposed on the second mounting seat 341. The X-direction drive unit 33 includes an X-direction guide rail and a second belt transmission module. The card pushing unit 31 is slidably disposed on the X-direction guide rail; the structure of the second belt transmission module can be designed with reference to the first belt transmission module 343. The belt of the second belt transmission module is connected to the card pushing unit 31.

[0056] Specifically, the card pushing unit 31 includes a mounting block 311 and a card pushing member 312. The mounting block 311 is slidably disposed on the X-guide rail, and the mounting block 311 is connected to the belt of the second belt transmission module. The card pushing member 312 is disposed on the mounting block 311.

[0057] A first through slot 13 is provided at the bottom of the card slot 11 along the X direction. A second through slot 14 is provided at the bottom of the card magazine base 1 along the Y direction. One end of the first through slot 13 extends to the edge of the card magazine base 1 on one side of the material outlet 213, and the other end is connected to the second through slot 14. One end of the second through slot 14 extends to one side edge of the card magazine base 1 so that the card pushing unit 31 can enter the second through slot 14.

[0058] The card pushing unit 31 and the temporary storage block 32 are arranged at intervals along the X direction, and a temporary storage slot is provided on the temporary storage block 32. When the reagent card 24 in the reagent card compartment 2 needs to be pushed out, 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 the opposite sides of one of the reagent card compartments 2, completing the preparation work of pushing the card. At this time, the card pushing assembly 3 is in the first state, the temporary storage slot is connected to the discharge port 213 of the corresponding reagent card compartment 2, and the card pushing unit 31 is located in the second slot 14.

[0059] Afterwards, the X-axis driving unit 33 can drive the card pushing unit 31 to move along the X-axis, so that the card pushing unit 31 enters the first through groove 13, and enters the box body 21 from the pushing notch 212, pushing the bottom reagent card 24 out of the discharge port 213, until the bottom reagent card 24 enters the temporary storage through groove of the temporary storage block 32.

[0060] Then, the first Y-axis driving unit 34 drives the card pushing unit 31 and the temporary storage block 32 to move together until the temporary storage slot is connected to the preset station. At this time, the card pushing assembly 3 is in the second state. In the second state, the X-axis driving unit 33 can drive the card pushing unit 31 to move, so as to push the reagent card 24 in the temporary storage slot into the preset station to complete 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 circumference of the incubation tray 6, and the incubation tray 6 can be rotated so that each slot can reach the preset station in turn. The incubation tray 6 is a conventional technology and will not be described in detail here.

[0061] The material blocking unit 23 includes a blocking plate 231 and a restoring member 232 .

[0062] The baffle 231 is arranged at the discharge port 213 and is hinged to the card storage 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 retaining 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 the retaining spring is in a deformed state. When the reagent card 24 is completely withdrawn, the baffle 231 is reset under the action of the retaining spring, thereby preventing the reagent card 24 in the box body 21 from being discharged.

[0063] The information identification piece is arranged on the outer wall of the box body 21, and the information identification piece can be an NFC chip.

[0064] The scanning assembly 4 includes a scanning piece 41 and a second Y-direction driving unit 42, and the second Y-direction driving unit 42 is connected to the scanning piece 41 and is used to drive the scanning piece 41 to move along the Y direction, so that the scanning piece 41 can scan the information identification pieces on each reagent card compartment 2 to complete the information identification of different reagent card compartments 2. The scanning piece 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 transmission module. The second Y-direction guide rail and the third belt transmission module are both arranged on the bracket. The scanning piece 41 is slidably arranged on the second Y-direction guide rail; the structure of the third belt transmission module can be designed with reference to the first belt transmission module 343. The scanning piece 41 is driven to slide along the second Y-direction guide rail by the third belt transmission module.

[0065] Example 2

[0066] The difference between the embodiment of the present application and embodiment 1 is that the card pushing assembly 3 is improved.

[0067] Specifically, Figure 1 , Figure 2 , Figures 8 to 10As shown, the card pushing assembly 3 also 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 transmission module 353. The third mounting seat 351 is slidably disposed on the X-direction guide rail and is connected to the belt of the second belt transmission module. The Z-direction guide rail 352 and the fourth belt transmission module 353 are both disposed on the third mounting seat 351; the mounting block 311 of the card pushing unit 31 is slidably disposed on the Z-direction guide rail 352; the mounting block 311 is connected to the fourth belt transmission module 353. The structure of the fourth belt transmission module 353 can be designed with reference to the first belt transmission module 343, and the card pushing unit 31 can be driven to move along the Z direction through the fourth belt transmission module 353.

[0068] The X direction, the Y direction and the Z direction are perpendicular to each other, wherein the Z direction may be a vertical direction, and the X direction and the Y direction are horizontal directions.

[0069] By driving the card pushing unit 31 to move up and down through the Z-direction driving unit 35 , the card pushing unit 31 can push out a plurality of reagent cards 24 at one time, thereby improving the card pushing efficiency.

[0070] The card pushing unit 31 further includes a partition plate 313 and a roller 314. The partition plate 313 is located above the card pushing member 312. The roller 314 is disposed below the partition plate 313 and is rotatably connected to the mounting block 311. The partition plate 313 is provided with an opening, and a portion of the roller 314 passes through the opening and is located above the opening.

[0071] When pushing the card, the X-direction driving unit 33 drives the card pushing unit 31 to move along the X-direction, and the partition plate 313 can be inserted between the first reagent card and the second reagent card, thereby separating the first reagent card from the second reagent card. Afterwards, 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 bottom of the second reagent card. When the card pushing unit 31 is in the card pushing process, the roller 314 rolls in contact with the second reagent card to avoid 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 thin, so it is easier to insert between the first reagent card and the second reagent card.

[0072] Afterwards, as the card pushing unit 31 moves, the card pushing member 312 pushes the first reagent card out of the discharge port 213 .

[0073] In the second state, the card pusher 312 pushes the first reagent card into the preset station. When the first reagent card includes multiple reagent cards 24, the card pusher 312 pushes only the reagent card 24 at the bottom of the temporary storage slot into the slot at the preset station each time, and pushes all the reagent cards 24 in the temporary storage slot into the respective slots of the incubation tray 6 in sequence through multiple card pushes.

[0074] 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 limited and matched 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 except the n reagent cards 24 from bottom to top.

[0075] For example, n may be equal to 2. That is, the card pushing unit 31 can push at most two reagent cards 24 out of the box body 21 at a time. The limiting portion 214 can limit the other reagent cards 24 except the two reagent cards 24 at the bottom, so as to prevent the other reagent cards 24 from shifting or tilting during the movement of the two reagent cards 24 pushed by the card pushing unit 31.

[0076] Further, 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 and make all the reagent cards 24 included in the second reagent card cooperate with the limiting portion 214 when entering below the second reagent card.

[0077] For example, when n is equal to 2, the card pushing unit 31 can push out one or two reagent cards 24 at a time. If the card pushing unit 31 pushes out only one reagent card 24 at a time, before pushing the card, the top height of the roller 314 is higher than the top height of the lowest reagent card 24, so that when the roller 314 enters below the second reagent card 24 from bottom to top, the other reagent cards 24 except the lowest reagent card 24 can be lifted, so that the other reagent cards 24 except the lowest reagent card 24 are mutually limited with the limiting portion 214, and even if only one reagent card 24 is pushed out at a time, the other reagent cards 24 will not be offset.

[0078] 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, and the sliding block 315 is driven up and down by the driving member to change the height of the sliding block 315, thereby changing the lifting height of the second reagent card. The driving member can be a conventional linear driving component such as a cylinder or a motor screw.

[0079] Furthermore, there may be a plurality of rollers 314. The heights of the plurality of rollers 314 are gradually reduced along the moving direction of the card pushing member 312. When each roller 314 gradually enters below the second reagent card, the height of the second reagent card can be gradually raised.
