Most of the existing reagent cards 100' are provided with a rectangular notch 200' at the bottom, and the hook card module matched with the reagent card 100' needs to move in three directions, X, Y and Z.

[0044] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0046] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0047] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0048] like Figure 1 As shown, a rectangular notch 200' is provided on the existing reagent card 100'. Since the rectangular notch 200' is a closed opening on all sides, motors need to be provided in the X, Y and Z directions respectively so that the reagent card 100' can move in the X, Y and Z directions respectively, thereby realizing the operation of the reagent card 100'. However, the number of motors is large and the space occupied is large, resulting in problems of difficult space layout and high production cost.
[0049] In order to solve this problem, this embodiment provides a reagent card structure, such as Figure 2 As shown, the reagent card structure includes a reagent card body 100, a notch 200 is provided at the bottom of the reagent card body 100, the notch 200 includes a feed portion 201 and a hook portion 202, the feed portion 201 is arranged along a first direction, the hook portion 202 is arranged along a second direction, and the feed portion 201 and the hook portion 202 are interconnected to form an L-shaped structure. Wherein, the appearance of the reagent card body 100 is similar to a rectangular parallelepiped structure, the length direction of the reagent card body 100 is defined as the first direction, the width direction of the reagent card body 100 is defined as the second direction, and the first direction and the second direction are perpendicular to each other. It should be noted that the first direction and the second direction only represent the spatial direction and have no substantial meaning.
[0050] The reagent card structure provided in this embodiment is provided with a notch 200 at the bottom of the reagent card body 100, the feed portion 201 of the notch 200 is arranged along the first direction, and the hook portion 202 of the notch 200 is arranged along the second direction, so that the reagent card body 100 only needs the hook mechanism 1 to move along the first direction and the second direction to achieve operation. Compared with the existing method that requires three directions, the operation action and process are simplified, and the production cost is effectively reduced. At the same time, the feed portion 201 is used for feeding the hook mechanism 1, so that the hook mechanism 1 initially enters the notch 200. The hook portion 202 is used for hooking the hook mechanism 1. The feed portion 201 and the hook portion 202 are connected to each other, so that the hook mechanism 1 can slide into the hook portion 202 through the feed portion 201. The feed portion 201 and the hook portion 202 not only guide the hook mechanism 1, but also limit the movement path of the hook mechanism 1. Compared with the rectangular notch 200, the L-shaped notch 200 has a small accommodating space, and the limiting effect of the hook mechanism 1 is good, which avoids the hook mechanism 1 from moving arbitrarily in the notch 200.
[0051] Furthermore, if Figure 3 As shown, a sample adding port 300 and an optical detection port 400 are provided on the top surface of the reagent card body 100. The sample adding port 300 is used to add samples to the reagent card body 100 for incubation of the reagent card body 100. The optical detection port 400 is used to detect the reagent card body 100 and to detect the performance indicators of the reagent card body 100.
[0052] In order to detect the performance indicators of the reagent card body 100, this embodiment provides a fluorescent immunoassay analyzer, such as Figure 3 As shown, the fluorescent immunoassay analyzer includes a frame 7, a shell 8 and a device body, the shell 8 is arranged on the frame 7, the frame 7 plays a role of overall support, the device body is arranged inside the shell 8, and the shell 8 plays a role of protecting the device body. The shell 8 is similar to a rectangular box structure, the width direction of the shell 8 is specifically the first direction, the length direction of the shell 8 is specifically the second direction, and the height direction of the shell 8 is the third direction.
[0053] like Figure 4-5 As shown, the device body includes a hook mechanism 1, a sample injection mechanism 2, a sample adding mechanism 3 and an incubation mechanism 4. The sample injection mechanism 2 is used to carry the sample, and the sample injection mechanism 2 plays a role in supporting the sample. The sample adding mechanism 3 is used to place the sample in the sample adding port 300 of the reagent card body 100. The hook mechanism 1 is used to insert into the notch 200 of the reagent card body 100 and transport the reagent card body 100 to the incubation mechanism 4. The incubation mechanism 4 is used to incubate the reagent card body 100 with the sample.
[0054] In the fluorescent immunoassay analyzer provided in this embodiment, after placing the sample on the sample injection mechanism 2, the hook mechanism 1 is used to insert into the notch 200 of the reagent card body 100 and transport it, the sample adding mechanism 3 is used to place the sample in the sample adding port 300 of the reagent card body 100, the hook mechanism 1 can insert the reagent card body 100 with the sample, and the incubation mechanism 4 is used to incubate the reagent card body 100 with the sample. Through the cooperation of the sample injection mechanism 2, the sample adding mechanism 3, the incubation mechanism 4 and the hook mechanism 1, the operation process of the reagent card body 100 is continuous and without intervals, and the production efficiency is high.
[0055] Optionally, the sample introduction mechanism 2 can be a carrier, which plays the role of carrying samples. The operator can manually place the samples on the carrier in sequence. Preferably, multiple samples are stacked and placed on the carrier in sequence to reduce the time for the operator to repeatedly load materials, and multiple samples only occupy space height, saving the space occupied by the carrier.
[0056] Optionally, the sample loading mechanism 3 includes a manipulator and a grabbing assembly, the output end of the manipulator is connected to the grabbing assembly, the grabbing assembly is used to grab the sample set on the stage, and the manipulator can drive the grabbing assembly to move along the first direction, the second direction and the third direction respectively to complete the sample delivery. Preferably, the adsorption assembly includes a vacuum generator and a suction cup, the vacuum generator is connected to the suction cup, and the vacuum generator can extract the air in the suction cup so that the suction cup generates negative pressure to adsorb the sample. In this way, damage to the sample when it is clamped is avoided to ensure the flatness of the sample surface.
[0057] Alternatively, if Figure 5 As shown, the incubation mechanism 4 includes an incubation platform 41, on which a plurality of incubation chambers 411 are arranged in parallel and spaced apart along the second direction, each incubation chamber 411 corresponds to an incubation station 001, and each incubation chamber 411 is used to accommodate and incubate a reagent card body 100, and the incubation chamber 411 is a cavity structure, which plays a role in limiting the reagent card body 100. The incubation chamber 411 is an open structure at one end, and the opening of the incubation chamber 411 is arranged toward the hook mechanism 1, so that the hook mechanism 1 can push the reagent card body 100 into the incubation chamber 411 through the opening. In this embodiment, the number of incubation chambers 411 is preferably twelve, so that the incubation mechanism 4 can incubate twelve reagent card bodies 100 at the same time. It can be understood that the incubation time and the time of loading and unloading the reagent card body 100 need to match to avoid the situation of waiting for the hook mechanism 1 to stop, and the production efficiency is high.
[0058] After the reagent card body 100 is incubated, in order to perform performance testing, the fluorescent immunoassay analyzer further includes a detection mechanism 6, which is disposed on the card hook mechanism 1 and is used to detect the incubated reagent card body 100. Optionally, the detection mechanism 6 is an optical detection module, specifically a CCD camera or the like.
[0059] After the reagent card body 100 completes the test, it needs to be withdrawn from the fluorescent immunoassay analyzer to achieve cyclic testing. For this purpose, a card withdrawal cavity is also provided on one side of the incubation platform 41. The card withdrawal cavity and the incubation cavity 411 are arranged in parallel. The card withdrawal cavity is a cavity structure, which plays a role in limiting the position of the reagent card body 100. The card withdrawal cavity corresponds to the card withdrawal station 003. The side of the card withdrawal cavity close to the hook card mechanism 1 is the entrance, and the side of the card withdrawal cavity away from the hook card mechanism 1 is the exit. When the hook card mechanism 1 transports the incubated reagent card body 100 to the entrance of the card withdrawal cavity, the hook card mechanism 1 continues to push the reagent card body 100, so that the previous reagent card body 100 is ejected from the exit of the card withdrawal cavity. At this time, the reagent card body 100 is accommodated in the card withdrawal cavity, and the reagent card body 100 on the next side will be ejected again.
[0060] This embodiment also provides a card hook mechanism 1 for conveying a reagent card structure, such as Figure 5-6 As shown, the hook mechanism 1 includes a first moving component 11, a hook component 12 and a second moving component 13. The first moving component 11 is connected to the hook component 12. The first moving component 11 is configured to drive the hook component 12 to enter the feeding part 201 of the reagent card body 100 along the first direction and slide with it. The second moving component 13 is connected to the first moving component 11. The second moving component 13 is configured to drive the first moving component 11 to drive the hook component 12 to move along the second direction into the hook part 202 of the reagent card body 100 and slide with it, so that the first moving component 11 can drive the hook component 12 and the reagent card body 100 to move along the first direction.
[0061] In the hook mechanism 1 provided in this embodiment, the first moving component 11 drives the hook component 12 to move along the first direction, so that the hook component 12 enters the feed part 201 from the notch 200, and then the second moving component 13 drives the hook component 12 to enter the hook part 202 along the second direction through the first moving component 11, so that the hook component 12 hooks the reagent card body 100. After hooking, the first moving component 11 can drive the hook component 12 and drive the reagent card body 100 to move along the first direction to realize the transportation of the reagent card body 100. Since the moving direction of the first moving component 11 and the extension direction of the hook part 202 are perpendicular to each other, the fixing effect between the hook component 12 and the reagent card body 100 is good. At the same time, the hook mechanism 1 only requires the first moving component 11 and the second moving component 13 to move in two directions, saving production costs, and has a compact layout, a small footprint, and maximizes space utilization.
[0062] Furthermore, if Figure 5-Figure 6 As shown, the first moving assembly 11 includes a first mounting plate 111, a first driving source 112, a first driving wheel 113, a first driven wheel (not shown in the figure), and a first conveyor belt 114. The first mounting plate 111 is arranged on the frame 7, the first driving source 112 is arranged on the first mounting plate 111, and the first driving wheel 113 and the first driven wheel are rotatably arranged on the first mounting plate 111. The first mounting plate 111 plays the role of installation and fixing. The first driving source 112 is specifically a first motor, and the output end of the first driving source 112 is connected to the first driving wheel 113. The first conveyor belt 114 is respectively tensioned and wound around the first driving wheel 113 and the first driven wheel and connected to the hook assembly 12. The first driving source 112 can drive the first driving wheel 113 to rotate, and drive the rotation of the first driven wheel and the movement of the first conveyor belt 114 and the hook assembly 12, so as to convert the rotational motion of the first driving source 112 into the linear motion of the first conveyor belt 114, thereby realizing the movement of the hook assembly 12 along the first direction.
[0063] Furthermore, if Figure 6 As shown, the hook assembly 12 includes a hook rod 121 and a first slider 122. The first slider 122 is connected to the first conveyor belt 114 and the hook rod 121 of the first moving assembly 11. The first slider 122 plays the role of an intermediate connection between the first conveyor belt 114 and the hook rod 121. The first slider 122 is preferably fixedly connected to the first conveyor belt 114 through a mounting seat. As the first slider 122 moves along the first direction, the hook rod 121 is driven to move along the first direction. The hook rod 121 is a rod-shaped structure. Since the notch 200 is set at the bottom of the reagent card body 100, the hook rod 121 is set in the vertical direction, that is, the hook rod 121 is set in the second direction, so that the hook rod 121 is directly inserted into the notch 200 located at the bottom of the reagent card body 100, which facilitates the hook rod 121 to be inserted into the notch 200.
[0064] In order to ensure the moving direction of the first slider 122, a first guide rail 115 is arranged on the first mounting plate 111 along the first direction, and a first sliding groove is arranged on the first slider 122. The first sliding groove slides in conjunction with the first guide rail 115 to play a guiding role, thereby ensuring the smooth movement of the first slider 122 along the first direction.
[0065] When the hook rod 121 moves in the first direction, the hook rod 121 will hit the reagent card body 100, causing a rigid collision between the hook rod 121 and the reagent card body 100 and causing damage. In order to solve this problem, the hook card assembly 12 also includes a connecting block 123, a connecting rod 124 and a reset member 125. The connecting block 123 is connected to the hook rod 121, one end of the connecting rod 124 is connected to the first slider 122, and the other end is inserted through the connecting block 123 and slidably cooperates with it. The connecting rod 124 plays the role of connecting the first slider 122 and the connecting block 123. The reset member 125 is specifically a columnar spring, which is sleeved on the connecting rod 124, and the two ends of the reset member 125 can respectively abut against the connecting block 123 and the first slider 122.
[0066] When the hook rod 121 hits the reagent card body 100, the reagent card body 100 will give the hook rod 121 an impact force, and the impact force causes the connecting block 123 to slide relative to the connecting rod 124 in the direction away from the hook rod 121. The connecting rod 124 guides the connecting block 123. During this process, the connecting block 123 gradually compresses the reset member 125. The reset member 125 located between the connecting block 123 and the first slider 122 plays a buffering role to offset the impact force, thereby avoiding the first motor from losing step due to the impact, so as to ensure the accuracy of the hook card assembly 12 moving along the first direction.
[0067] It is understandable that the reagent card body 100 is a rectangular parallelepiped structure, and the notch 200 is only provided on one side of the reagent card body 100. If the hook rod 121 only hooks the notch 200 and drives the reagent card body 100 to move, although the movement of the reagent card body 100 can be achieved, the reagent card will be tilted due to the single-sided load. In order to solve this problem, Figure 5-Figure 6 As shown, the hook mechanism 1 also includes a limit block 5, which is arranged on the first mounting plate 111 of the first moving component 11, and a limit cavity 51 is opened in the limit block 5 along the first direction. The limit cavity 51 is a cavity structure, and the reagent card structure can be slidably matched with the limit cavity 51. The limit cavity 51 is used for limiting the reagent card structure.
[0068] With this arrangement, under the driving action of the first moving component 11, after the hook rod 121 is inserted into the notch 200 of the reagent card structure, the reagent card body 100 can be directly pulled into the limiting cavity 51, and the limiting cavity 51 plays the role of accommodating the reagent card body 100. The top surface, bottom surface and two side surfaces of the limiting cavity 51 limit the reagent card structure, avoiding the situation where the reagent card structure is tilted when moving along the first direction. At the same time, under the driving action of the second moving component 13, when the first moving component 11 and the reagent card structure move together along the second direction, the reagent card structure is always in the limiting cavity 51, avoiding the situation where the reagent card structure is tilted when moving along the second direction.
[0069] Preferably, the hook rod 121 is passed through the limiting cavity 51 and slidably cooperates with it. Specifically, a through hole is provided at the bottom of the limiting block 5, and the through hole is provided along the first direction. The through hole is connected with the limiting cavity 51, and the hook rod 121 extends into the limiting cavity 51 through the through hole. The hook rod 121 can slide along the through hole. The through hole not only plays a guiding role, but also further limits the moving direction of the hook rod 121.
[0070] It should be particularly noted that the detection mechanism 6 is preferably arranged on the limit block 5, and a through hole is provided on the top surface of the limit block 5, the through hole is connected to the limit cavity 51, the detection mechanism 6 and the through hole are arranged opposite to each other, and the detection mechanism 6 detects the reagent card structure through the through hole. At this time, the limit cavity 51 provides the reagent card structure with a closed space required for detection to ensure the accuracy of the detection.
[0071] Furthermore, if Figure 5 As shown, the second moving assembly 13 includes a second mounting plate 131, a second driving source 132, a second driving wheel (not shown in the figure), a second driven wheel 133 and a second conveyor belt 134. The second mounting plate 131 is arranged on the frame 7, and the second driving source 132 is arranged on the frame 7. The second driving wheel and the second driven wheel 133 are rotatably arranged on the second mounting plate 131, and the second mounting plate 131 plays the role of installation and fixing. The second driving source 132 is specifically a second motor, and the output end of the second driving source 132 is connected to the second driving wheel. The second conveyor belt 134 is respectively tensioned and wound on the second driving wheel and the second driven wheel 133 and connected to the first mounting plate 111 of the first moving assembly 11. The second driving source 132 can drive the second driving wheel to rotate, and drive the rotation of the second driven wheel 133 and the movement of the second conveyor belt 134 and the hook assembly 12, so as to convert the rotational motion of the second driving source 132 into the linear motion of the second conveyor belt 134, thereby realizing the movement of the hook assembly 12 along the second direction.
[0072] In order to ensure the smooth movement of the hook assembly 12 along the second direction, a second guide rail 135 is provided on the second mounting plate 131 along the second direction, and a second slider is provided at the bottom of the first mounting plate 111. The second slider and the second guide rail 135 are slidably matched to play a guiding effect to ensure the smooth movement of the first moving assembly 11 along the second direction. Preferably, a through hole is provided in the middle of the first mounting plate 111, and a guide rod is provided on the second mounting plate 131 along the second direction. The guide rod passes through the through hole and slides with the second mounting plate 131 to play a guiding role. The mutual cooperation between the second guide rail 135 and the guide rod plays a double guiding role on the left and right of the first mounting plate 111 to ensure the smooth movement.
[0073] It can be understood that there are a total of fifteen fixed positions of the hook card assembly 12 along the second direction, including twelve incubation stations 001, one reagent card station 002, one card withdrawal station 003 and one zero position. The zero position is the initial position of the hook card assembly 12, and the reagent card station 002 is the initial position for feeding the reagent card.
[0074] When starting to work, the hook card assembly 12 is in zero position. After placing the sample on the sample injection mechanism 2, under the driving action of the first moving assembly 11, the hook card mechanism 1 is inserted into the notch 200 of the reagent card body 100 and hooks it into the limit cavity 51. The sample adding mechanism 3 is used to place the sample in the sample adding port 300 of the reagent card body 100. Under the driving action of the second moving assembly 13, the hook card mechanism 1 can transport the reagent card body 100 with the sample to the incubation mechanism 4. The incubation station 001 of the incubation mechanism 4 is used to incubate the reagent card body 100 with the sample. After the incubation is completed, the reagent card body 100 is hooked back into the limit cavity 51 and tested by the detection mechanism 6. After the test is completed, the hook card mechanism 1 transports the reagent card body 100 to the card withdrawal station 003. After the previous reagent card body 100 as a waste card is pushed out of the rack 7, the hook card mechanism 1 returns to zero position, completing a cycle and waiting for the next test.
[0075] It should be noted that in order to ensure that the entire working cycle proceeds in an orderly manner, a plurality of position sensors 9 are arranged on the frame 7. The position sensor 9 is specifically an optical coupler. Each position sensor 9 is used to detect a fixed position. When the hook assembly 12 triggers the position sensor 9 located at a fixed position, the position sensor 9 transmits the position signal to the controller, and the controller controls the next action to start. The various mechanisms cooperate closely and the production efficiency is high.
