Description

Technical Field

[0001] This invention relates to the field of reagent detection technology, and in particular to a reagent card delivery device and a fluorescence immunoassay analyzer. Background Technology

[0002] Fluorescence immunoassay (FIA) is an immunoassay technique that uses fluorescently labeled antibodies or antigens as tracers. Typically, in a laboratory, when a liquid sample to be tested is delivered, it is placed in individual sample tubes. The operator manually draws the sample liquid from the sample tube, injects it into a test reagent card, and then places the test reagent card containing the liquid sample into the fluorescence immunoassay analyzer for analysis.

[0003] Previously, after the operator injected the sample solution from the sample reagent tube into the test reagent card, several reagent cards needed to be installed in a cartridge box with an open end. When testing was needed, each reagent card had to be manually removed from the cartridge box and placed in the fluorescence immunoassay analyzer for testing. However, because the gap between the reagent card and the inner wall of the cartridge box was small, it was not convenient to manually remove the reagent cards, which caused inconvenience to the sample testing work. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and to propose a reagent card pushing device and a fluorescence immunoassay device, thereby solving the technical problem that reagent cards are inconvenient to remove from the magazine in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a reagent card dispensing device, comprising:

[0006] The frame includes a support platform and at least two limiting frames. Each limiting frame is fixed to the support platform at intervals along the length direction of the frame. Adjacent limiting frame supports form a placement space that extends along the width direction of the frame and allows magazines to be placed. A slot is provided on one side of the placement space.

[0007] The push unit includes a drive module and a push module. One end of the push module is provided with a push end, which is located within the placement space. The drive module is driven to connect with the push module and is used to drive the push module to move back and forth along the width direction of the rack, so that the push end pushes one of the reagent cards in the magazine box of the placement space out of the placement space through the card outlet.

[0008] Optionally, the frame further includes a dehumidification module and an enclosure frame. The enclosure frame is fixed to the support platform, and the dehumidification module is fixed to the top of the enclosure frame. The support platform, the enclosure frame, and the dehumidification module enclose a sealed receiving cavity. Each of the limiting frames is located inside the receiving cavity, and the dehumidification module is used to dehumidify the receiving cavity.

[0009] Optionally, the support platform is provided with a plurality of elastic sealing modules spaced apart along the length of the frame. Each elastic sealing module is located between each limiting frame. Each elastic sealing module is provided with an interpenetration gap. Each interpenetration gap extends toward the width of the frame. The pushing end passes through the interpenetration gap from below the elastic sealing module and extends to the placement space. The driving module is used to drive the pushing end to move back and forth along the interpenetration gap. The interpenetration gap can close automatically under the force of the elastic sealing module itself.

[0010] Optionally, the support platform is further provided with a plurality of support plates spaced apart along the length of the frame, and an installation space is formed between each support plate. The elastic sealing module includes two elastic elements arranged opposite each other. Both elastic elements are located within the installation space. The opposite sides of the two elastic elements are fixedly connected to the support plate. The opposite sides of the two elastic elements are attached to each other to form the interlocking gap. The interlocking gap can be self-adhesive under the elastic force of the elastic elements.

[0011] Optionally, a soft magnetic strip is fixed to each of the two elastic elements on their opposite sides, and the opposite sides of the elastic elements adhere to each other by the elastic force of the elastic elements themselves and the magnetic force of the soft magnetic strip.

[0012] Optionally, the elastic member has an elastic cavity extending along its length, which accommodates the deformation of the elastic member toward the elastic cavity so that the pushing end passes through the elastic cavity.

[0013] Optionally, the support plate includes two clamping plates arranged opposite each other, and each of the two elastic elements has a clamping part on its opposite side, the clamping part extending between the two clamping plates and being fixedly connected to the clamping plates.

[0014] Optionally, a frame door is provided on one side of the enclosure frame. The frame door is hinged to the enclosure frame, and the end of each support plate and each elastic member near the frame door extends toward the height direction of the frame and is sealed and fitted to the bottom of the frame door.

[0015] Optionally, the card dispensing port is provided on the enclosure frame, and the enclosure frame is also provided with a sealing door. The sealing door is covered on the card dispensing port and hinged to the enclosure frame. The sealing door can rotate outward of the enclosure frame under the push of the reagent card to open the card dispensing port, and rotate inward of the enclosure frame under its own force to close the card dispensing port.

[0016] Compared with the prior art, the reagent card pushing device provided by the present invention has the following advantages: by setting a frame and a pushing unit, the frame includes a support platform and at least two limiting frames. The at least two limiting frames are fixed at intervals on the support platform along the length direction of the frame, and the adjacent limiting frame supports form a placement space extending along the width direction of the frame. The pushing unit is equipped with a driving module and a pushing module. The pushing module is equipped with a pushing end. When pushing the reagent card, the cartridge box is placed with its opening facing down in the placement space. The reagent card at the bottom will slide down from the cartridge box to the bottom of the cartridge box. Since the pushing end can move into the placement space, the pushing module can move along the width direction of the frame by driving the pushing module, so that the pushing end pushes the reagent card in the cartridge box out of the card outlet from the placement space, thereby realizing the removal of the reagent card from the cartridge box and providing convenience for the removal of the reagent card from the cartridge box.

[0017] To achieve the above-mentioned technical objectives, the present invention provides a fluorescence immunoassay device, including a fluorescence immunoassay apparatus and a reagent card pushing device, wherein the fluorescence immunoassay apparatus is used to perform fluorescence immunoassay on the reagent cards pushed out by the reagent card pushing device.

[0018] Compared with the prior art, the reagent card pushing device provided by the present invention has the following advantages: by setting the reagent card pushing device, the fluorescence immunoassay device can facilitate the fluorescence immunoassay of samples. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] This invention provides a reagent card delivery device and a fluorescence immunoassay analyzer.

[0039] Example 1

[0040] Embodiment 1 of the present invention provides a card pushing device, such as Figures 1-4As shown, the device includes a frame 10 and a push unit 20. The frame 10 includes a support platform 11 and at least two limiting frames 12. Each limiting frame 12 is fixed to the support platform 11 at intervals along the length direction of the frame 10. The adjacent limiting frames 12 support each other to form a placement space 121 that extends along the width direction of the frame 10 and is used to place the magazine 20a. A card outlet 1211 is provided on one side of the placement space 121. The push unit 20 includes a drive module (not shown) and a push module 21. One end of the push module 21 is provided with a push end 211, which is located in the placement space 121. The drive module is driven to the push module 21 and is used to drive the push module 21 to move back and forth along the width direction of the frame 10 so that the push end 211 pushes one of the reagent cards 10a in the magazine 20a in the placement space 121 out of the placement space 121 through the card outlet 1211.

[0041] Specifically, the reagent card 10a pushing device comprises a frame 10 and a pushing unit 20. The frame 10 includes a support platform 11 and at least two limiting frames 12. The at least two limiting frames 12 are fixed at intervals along the length of the frame 10 on the support platform 11. The adjacent limiting frames 12 support each other to form a placement space 121 extending along the width of the frame 10. The pushing unit 20 comprises a drive module and a pushing module 21. The pushing module 21 is provided with a pushing end 211. When pushing the reagent card 10a, the cartridge box 20a is placed with its opening facing downwards in the placement space 121. The two sides of the cartridge box 20a can be pushed in by the limiting frames 12. With the limit switch in place, the reagent card 10a at the bottom will slide down from the cartridge box 20a to the bottom of the cartridge box 20a. Since the push end 211 can move into the placement space 121, the push module 21 can be driven to move along the width direction of the frame 10 so that the push end 211 applies a pushing force from the end of the reagent card 10a, or applies a frictional force along the bottom surface of the reagent card 10a, pushing the reagent card 10a in the cartridge box 20a out of the card outlet 1211 and pushing it out of the placement space 121. This will facilitate the removal of the reagent card 10a from the cartridge box 20a.

[0042] In this embodiment, as Figure 6As shown, the magazine 20a has an extension 21a near the opening, and a support protrusion 22a is provided on the inner side of the extension 21a. When the magazine 20a is installed in the placement space 121 with the opening facing downwards, the end of the extension 21a fits against the surface of the support platform 11 to support the magazine 20a. The reagent card 10a at the bottom layer will slide from inside the magazine 20a to the bottom of the magazine 20a and be supported by the support protrusion 22a. When the push end 211 is pushing, the push end 211 first moves to the end of the reagent card 10a that has fallen on the support block, and then pushes the reagent card 10a a certain distance toward the card outlet 1211, pushing part of the reagent card 10a out of the card outlet 1211. After the reagent card 10a is completely removed, the push end 211 retracts to the side of the magazine 20a so that the upper reagent card 10a falls onto the support protrusion 22a by gravity. In this embodiment, during the process of pushing the reagent card 10a out of the placement space 121, after a portion of the reagent card 10a is pushed out of the outlet 1211, the reagent card 10a is then completely pushed out of the outlet 1211 by manual operation or a clamping mechanism using the portion that extends out of the outlet 1211.

[0043] In this embodiment, as Figures 1-3 As shown, the frame 10 also includes an enclosure frame 13 and a dehumidification module 14. The enclosure frame 13 is fixed to the support platform 11, and the dehumidification module 14 is fixed to the top of the enclosure frame 13. The support platform 11, the enclosure frame 13, and the dehumidification module 14 together form a sealed receiving cavity 15. Each limiting frame 12 is located inside the receiving cavity 15. The dehumidification module 14 is used to dehumidify the receiving cavity 15. Specifically, since the enclosure frame 13, the dehumidification module 14, and the support platform 11 form a sealed receiving cavity 15, external dust and moisture can be effectively prevented from entering the receiving cavity 15, thereby protecting the magazine box 20a and reagent card 10a installed in the placement space 121. The dehumidification module 14 can further dehumidify the receiving cavity 15.

[0044] In this embodiment, further, as Figure 1As shown, the card dispensing port 1211 is disposed on the enclosing frame 13, and the enclosing frame 13 is also provided with a sealing door 1212. The sealing door 1212 covers the card dispensing port 1211 and is hinged to the enclosing frame 13. The sealing door 1212 can rotate outward of the enclosing frame 13 under the push of the reagent card 10a to open the card dispensing port 1211, and rotate inward of the enclosing frame 13 under its own force to close the card dispensing port 1211. Specifically, when the pushing end 211 drives the reagent card 10a to dispense from the card dispensing port 1211, the reagent card 10a will drive the sealing door 1212 to open. After the reagent card 10a is pushed out, the sealing door 1212 rotates inward of the enclosing frame 13 under its own force to automatically close the card dispensing port 1211. By setting the sealing door 1212, the receiving cavity 15 is sealed without affecting the ejection of the reagent card 10a from the card outlet 1211.

[0045] Understandably, the sealing door 1212 is equipped with a torsion spring at the hinge of the enclosure frame 13, and the enclosure frame 13 rotates on its own through the elastic force of the torsion spring. Alternatively, magnetic components are provided on the sealing door 1212 and the enclosure frame 13, and the sealing door 1212 rotates on its own through the magnetic force exerted by the enclosure frame 13 on the sealing door 1212.

[0046] In this embodiment, further, such as Figures 1-4 As shown, the dehumidification module 14 includes a housing 141, a fan 142, and a desiccant (not shown in the figure). The housing 141 is fixed to the top of the enclosure frame 13. A vent hole (not shown in the figure) is fixed on the side of the housing 141 near the enclosure frame 13. The desiccant is placed inside the housing 141. The fan 142 is fixed to the top of the housing 141 and is used to blow the gas dried by the desiccant inside the housing 141 through the vent hole to the receiving cavity 15, thereby achieving dehumidification of the air inside the receiving cavity 15.

[0047] In this example, further, such as Figures 3-4 As shown, each limiting frame 12 is provided with a ventilation slot 122 for the fan 142 to draw air. The ventilation slot 122 facilitates the fan 142 to draw air into the receiving cavity 15, thereby improving the dehumidification effect of the dehumidification module 14.

[0048] Understandably, the drive module can be any drive component that can move the push module 21 in the width direction of the frame 10, such as a cylinder, hydraulic cylinder, motor, or lead screw. Alternatively, the push module 21 can be mounted on a slide extending in the width direction of the frame 10 to achieve stable movement of the push module 21 in the width direction of the frame 10.

[0049] In this embodiment, as Figures 2-5As shown, the support platform 11 is provided with a number of elastic sealing modules 111 spaced apart along the length direction of the frame 10. Each elastic sealing module 111 is located between each limiting frame 12. Each elastic sealing module 111 is provided with an insertion gap 1111. Each insertion gap 1111 extends in the width direction of the frame 10. The pushing end 211 passes through the insertion gap 1111 from below the elastic sealing module 111 and extends to the placement space 121. The driving module is used to drive the pushing end 211 to move back and forth along the insertion gap 1111. The insertion gap 1111 can close automatically under the force of the elastic sealing module 111 itself. Specifically, since the interpenetration gap 1111 can close by itself under the force of the elastic sealing module 111, it can effectively seal the support platform 11. This allows the push end 211 to pass through the support platform 11 and move along the support platform 11 in the direction of the frame 10, while simultaneously achieving uninterrupted sealing of the support platform 11, thereby effectively protecting the reagent card 10a in the receiving cavity 15.

[0050] Understandably, the entire support platform 11 can be made into an elastic plate, so that the interlacing gap 1111 can be closed by the elastic force of the plate itself. Alternatively, multiple soft magnetic strips can be set, and the interlacing gap 1111 can be closed by the attraction between the soft magnetic strips. Or, a zipper structure can be set in the interlacing gap 1111, and the interlacing gap 1111 can be sewn together by the zipper structure.

[0051] In this embodiment, as Figures 2-5 As shown, the support platform 11 is also provided with several support plates 112 spaced apart along the length of the frame 10, forming an installation space 113 between each support plate 112. The elastic sealing module 111 includes two opposing elastic elements 1112, both of which are located within the installation space 113. The opposite sides of the two elastic elements 1112 are fixedly connected to the support plate 112, and the opposite sides of the two elastic elements 1112 are pressed together to form an interlocking gap 1111. The interlocking gap 1111 can automatically close under the elastic force of the elastic elements 1112. Specifically, the support plate 112 facilitates the connection between the enclosure frame 13 and the limiting frame 12, improving the stability of the frame 10 structure. The two elastic elements 1112 can form an interlocking gap 1111, thereby achieving the automatic closing of the interlocking gap 1111 while stabilizing the frame 10.

[0052] Understandably, the elastic element 1112 can be bonded to the side of the support platform 11 to achieve stability in the installation space 113, or the elastic element 1112 can be fixed to the support platform 11 by fasteners.

[0053] In this embodiment, the elastic element 1112 is further defined as an elastic rubber strip.

[0054] In this embodiment, further, as Figures 3-4 As shown, each limiting frame 12 is fixed to each support plate 112.

[0055] In this embodiment, a soft magnetic strip (not shown in the figure) is fixed to the opposite side of each of the two elastic members 1112. The opposite sides of the elastic members 1112 adhere to each other by the elastic force of the elastic members 1112 themselves and the magnetic attraction of the soft magnetic strip. Specifically, by setting the soft magnetic strip, the adhesion speed of the two elastic members 1112 can be accelerated, further improving the sealing of the receiving cavity 15.

[0056] In this embodiment, further, as Figures 3-5 As shown, the elastic member 1112 has an elastic cavity 1113 extending along its length. The elastic cavity 1113 accommodates the deformation of the elastic member 1112 towards the elastic cavity 1113, allowing the pushing end 211 to pass through the elastic cavity 1113. Specifically, the elastic cavity 1113 facilitates the deformation of the elastic member 1112, effectively reducing the resistance when the pushing end 211 moves along the interlocking gap 1111. This achieves efficient fitting of the elastic member 1112 while reducing the driving force required by the driving module to drive the pushing module 21.

[0057] In this embodiment, further, as Figures 3-5 As shown, the support plate 112 includes two clamping plates 1121 arranged opposite to each other. Each of the two elastic members 1112 has a clamping portion 1114 on its opposite side, extending between the two clamping plates 1121 and fixedly connected to them. Specifically, the arrangement of the two clamping plates 1121 and the clamping portion 1114 ensures the elastic member 1112 is securely attached to the support plate 112, while also achieving a highly efficient seal between the elastic member 1112 and the support plate 112.

[0058] In this example, further, such as Figure 1 and 3 As shown in Figure 4, a connecting plate 131 is provided on one side of the enclosing frame 13, and a connecting protrusion 123 is provided on the side of each limiting frame 12 near the connecting plate 131. A connecting insertion hole 1311 is provided on the connecting plate 131, and the connecting protrusion 123 is inserted into the connecting insertion hole 1311. Specifically, through the cooperation of the connecting protrusion 123 and the connecting insertion hole 1311, the stability of the connecting plate 131 and each limiting frame 12 can be effectively achieved, thereby improving the stability of the reagent card 10a pushing process.

[0059] In this example, the connecting plate 131 is further fixedly connected to the connecting protrusion 123 by a threaded connector.

[0060] In this embodiment, further, as Figures 1-2As shown, a frame door 132 is also provided on the other side of the enclosure frame 13. The frame door 132 is hinged to the enclosure frame 13. The ends of each support plate 112 and each elastic member 1112 near the frame door 132 extend towards the height direction of the frame 10 and are sealed and fitted to the bottom of the frame door 132. Specifically, with the above arrangement, when installing the magazine box 20a into the placement space 121, the frame door 132 is opened first, then the end of the magazine box 20a with the opening faces the receiving cavity 15, and the magazine box 20a is set horizontally, supported by the ends of the support plate 112 and the elastic member 1112. Then, the magazine box 20a is quickly rotated towards the receiving cavity 15 with the supporting parts of the support plate 112 and the elastic member 1112 as the fulcrum, so that the magazine box 20a can be installed in the placement space 121, achieving efficient installation of the magazine box 20a.

[0061] The specific implementation process of Embodiment 1 of the present invention is as follows: When taking out the reagent card 10a and the magazine box 20a, the frame door 132 is opened first, and then the magazine box 20a containing the reagent card 10a is placed into the placement space 121, so that the bottom reagent card 10a will fall out of the magazine box 20a from the opening and be supported by the support block. The drive module drives the push module 21 to move towards the card outlet 1211, and then pushes the bottom reagent card 10a in the magazine box 20a towards the card outlet 1211. After the reagent card 10a is completely pushed out, the push end 211 retracts to one side of the magazine box 20a so that the upper reagent card 10a slides to the support block by gravity, and the above cycle is repeated until all the reagent cards 10a in the magazine box 20a are pushed out.

[0062] Example 2

The fluorescence immunoassay apparatus is used to perform fluorescence immunoassay on reagent cards pushed out by the reagent card delivery device. Specifically, the fluorescence immunoassay device, by incorporating the reagent card delivery device, facilitates the fluorescence immunoassay of samples.

[0064] Understandably, a fluorescence immunoassay device can be any device capable of performing fluorescence immunoassay on a sample.
