Description

Technical Field

[0001] This utility model relates to the field of reagent card storage equipment, specifically to a reagent card storage dehumidification device and a fully automated immunoassay analyzer. Background Technology

[0002] Immunochromatographic analyzers operate on the principle of antigen-antibody specific immune reactions, performing various tests on samples such as whole blood, capillary blood, serum, and plasma to aid in clinical diagnosis. To meet the demands for quantitative, qualitative, and high-throughput testing, while adhering to the trend towards automation and simplicity in point-of-care testing (POCT), immunochromatographic analyzers are required to possess the aforementioned advantages of high throughput and full automation.

[0003] Dry-type biochemical or immunoassay analyzers require the use of dry-sheet reagents during testing. These reagents degrade rapidly in humid environments. To maintain dryness and reduce manual handling, those skilled in the art store the reagents in a storage container connected to a dehumidifying chamber. However, existing technologies, such as patent application CN113581612A, disclose a reagent card storage device. This patent describes a dehumidifying structure connected to the reagent card storage unit via a dehumidifier to maintain the required temperature and humidity for the reagent cards within a relatively enclosed space. However, the structural layout of this reagent card storage device is unreasonable; the dehumidifier and reagent card pushing structure, among other related components, require a significant amount of horizontal space on the workbench, hindering instrument miniaturization.

[0004] In specific hospital or testing facility scenarios, existing fluorescence analyzers, when facing the operator on a laboratory workbench, are too wide, resulting in insufficient utilization of the limited space on the workbench. To address this issue, those skilled in the art require a new reagent card storage dehumidification device that effectively reduces the instrument's lateral width without exceeding the longitudinal width of the laboratory workbench, thereby improving the utilization rate of the instrument's layout space.

[0126] The storage dehumidification chamber 1 includes a dehumidification chamber shell 9 and a dehumidification chamber door 10. The dehumidification chamber shell 9 is disposed inside the instrument sealing chamber 2, and the dehumidification chamber door 10 is fixed to the front shell 7. The dehumidification chamber door 10 is used to place and remove the reagent card magazine 3 inside the storage dehumidification chamber 1. The dehumidification chamber door 10 is hinged to the front shell 7.

[0127] In order to ensure the sealing effect of the instrument sealing chamber 2 during the placement and removal of reagent card cartridges 3 in the storage dehumidification chamber 1.

[0128] See Figure 2 and Figure 11 , Figure 2 A schematic diagram showing the relative positions of the storage dehumidification chamber and the dehumidification equipment chamber in an embodiment of this utility model is provided. Figure 11 This diagram illustrates the relative positions of the storage space and the pre-dispensing space of the reagent card storage and dehumidification device in an embodiment of the present invention.

[0129] In this embodiment, the storage dehumidification chamber 1 is also provided with a card outlet for ejecting reagent cards, and a flexible sealing element 11 is provided at the card outlet position; when the reagent card is ejected from the card outlet, the flexible sealing element 11 opens under the push of the reagent card; after the reagent card is ejected, the flexible sealing element 11 recovers under its own deformation to seal the card outlet.

[0130] In this embodiment, in order to achieve dynamic closure of the push card window 12, the sealing effect of the storage dehumidification chamber 1 is improved.

[0131] See Figure 3 , Figure 3 A three-dimensional structural diagram of the bottom plate of the storage dehumidification chamber in an embodiment of this utility model is shown.

[0132] The bottom plate of the storage dehumidification chamber 1 is also provided with a push-lock window 12 extending along the depth direction of the storage dehumidification chamber 1, and a sealing mechanism for sealing the push-lock window 12; the sealing mechanism includes:

[0133] A sealing sheet 13 is adapted to the shape of the push card window 12 and is driven to open and close the push card window 12. The sealing sheet 13 is also provided with a push card pin hole 14 for triggering the push card window 12 to open.

[0134] The driving component 15 is connected to the sealing sheet 13 and applies pressure to the sealing sheet 13 to seal the push-block window 12, thereby sealing the storage dehumidification chamber 1.

[0135] When a reagent card is dispensed from the reagent card magazine 3, the pusher 28 of the pusher mechanism 27 inserts into the pusher pin hole 14 and drives the sealing plate 13 to slide. The drive member 15 stores energy and opens the pusher window 12, thus completing the pusher action. After the reagent card is dispensed from the reagent card magazine 3, the drive member 15 releases energy to drive the sealing plate 13 to reset and seal the pusher window 12, thereby achieving dynamic closure of the pusher window 12.

[0136] Furthermore, in order to ensure that when the card pusher mechanism 27 moves to any end of the sealing sheet 13, the driving member 15 drives the sealing sheet 13 to reset and seal the card pusher window 12.

[0137] The sealing sheet 13 has push-lock pin holes 14 and driving components 15 at both ends. The driving components 15 are springs located on the side of the sealing sheet 13 and connected at both ends to the sealing sheet 13 and the bottom plate of the storage dehumidification chamber 1, respectively.

[0138] In addition, to improve the guiding effect of the sealing action of the sealing sheet 13, the push-lock hole 14 is an inclined hole provided in the radial direction of the sealing sheet 13. When the push-lock member 28 of the push-lock mechanism 27 slides in the inclined hole, it guides the sealing sheet 13 to slide and open radially. The bottom plate of the storage dehumidification chamber 1 is also provided with a guide structure 16 for guiding the sliding of the sealing sheet 13. The guide structure 16 is a groove located on the bottom plate of the storage dehumidification chamber 1.

[0139] Furthermore, in this embodiment, in order to limit and fix the reagent card magazine 3 and guide its installation, the following structure is also provided in this utility model:

[0140] See Figures 4 to 6 , Figure 4 A schematic diagram of the internal structure of the storage dehumidification chamber is shown. Figure 5 A schematic diagram showing the location of the locking latch at the bottom of the reagent card magazine is provided. Figure 6 This embodiment is shown. Figure 3 A schematic diagram of glass beads installed in the glass bead receiving groove.

[0141] The bottom plate of the storage dehumidification chamber 1 is also provided with a positioning plate 17 that engages with the reagent card magazine 3, and glass beads 18 that guide the reagent card magazine 3 to engage and fix on the positioning plate 17; the bottom plate of the storage dehumidification chamber 1 is also provided with a glass bead receiving groove 47 for accommodating the glass beads 18. The positioning plate 17 can effectively position and fix the reagent card magazine 3, and the glass beads 18 can stably and reliably guide the reagent card magazine 3 into the positioning plate 17.

[0142] In addition, to further securely fix the reagent card magazine 3 to its base plate, a telescopic locking member 19 is provided at the bottom of the reagent card magazine 3. The locking member 19 engages with a locking groove on the base plate of the storage dehumidification chamber 1 to fix the reagent card magazine 3.

[0143] The top of the dehumidification chamber shell 9 is also provided with a magazine limiting pin 20; the magazine limiting pin 20 is located on both sides of the reagent card magazine 3, and is used to limit and fix the reagent card magazine 3 and prevent the reagent card magazine 3 from being misaligned during installation.

[0144] The top of the dehumidification chamber shell 9 is also provided with a magazine spring 21; the magazine spring 21 abuts against the top of the reagent card magazine 3 and is used to limit and fix the reagent card magazine 3.

[0145] In this embodiment, corresponding to the sealing mechanism described above, the opening and closing of the sealing mechanism is triggered by the push-card mechanism 27.

[0146] See Figure 9 and Figure 10 , Figure 9 A three-dimensional structural diagram of the card-pushing mechanism in an embodiment of this utility model is shown. Figure 10 The diagram shows the position of the bottom plate of the dehumidification equipment in an embodiment of the present invention, and the relative positions of the push-lock component and the sealing sheet.

[0147] The card-pushing mechanism 27 is disposed within the dehumidification equipment compartment 4; the card-pushing mechanism 27 includes:

[0148] Telescopic mechanism 29, which is an electromagnet, corresponds to the reagent card magazine 3 and slides along the length of the push-card window 12 under drive. The telescopic end of the telescopic mechanism 29 is the push-card component 28, which is used to open the sealing sheet 13 and push the reagent card out. Figure 10 and Figure 3 As shown, the push card component 28 extends out and is inserted into the push card pin hole 14. During the push card process, the push card component 28 pushes the sealing plate 13 and triggers the push card window 12 to open.

[0149] A drive slider 30 is provided with a plurality of telescopic mechanisms 29, which are controlled to extend and retract to achieve flexible selection of push cards in multiple channels.

[0150] A slider guide rail 31 is provided along the length of the push card window 12, and the drive slider 30 is slidably disposed on the slider guide rail 31.

[0151] The first drive motor 32 drives the drive slider 30 to slide on the slider guide rail 31 via a belt drive structure. When any channel needs to push a card, the electromagnet of the corresponding channel drives the card pusher 28 to extend, and the first drive motor 32 drives the card pusher 28 to push the card in the card release direction. Multiple telescopic mechanisms 29 are provided on the drive slider 30, allowing one drive motor 32 to drive multiple telescopic mechanisms 29 to complete the card pushing action, eliminating the need for multiple drive motors 32 and effectively reducing equipment costs. Furthermore, the combination of several electromagnet telescopic mechanisms 29 and a unidirectional motor drive with a flexibly sealed card pusher window 12 enables flexible card pushing selection across multiple channels, offering advantages such as simple structure and low cost.

[0152] The initial position detection component 33 is used to detect whether the drive slider 30 is in an initial state away from the card outlet; the initial position detection component 33 is an optical coupler detector;

[0153] The arrival position detection component 34 is used to detect whether the drive slider 30 is at a preset arrival position close to the card outlet; the arrival position detection component 34 is a micro switch.

[0154] In this embodiment, the refrigeration and dehumidification structure 5 can effectively achieve dehumidification and optimize the overall spatial layout of the reagent card storage dehumidification device.

[0155] See Figure 7 and Figure 8 , Figure 7 A three-dimensional structural diagram of the refrigeration and dehumidification structure installed on the bottom plate of the dehumidification equipment compartment is shown in an embodiment of the present invention. Figure 8 A side view of the refrigeration and dehumidification structure in an embodiment of the present invention is shown.

[0156] The cooling and dehumidification structure 5 is a semiconductor cooling structure, including: a TEC cooling chip 6, fins 22, a fan 23, and a heat-conducting component 24; the cold end of the TEC cooling chip 6 is connected to the fins 22 and the fan 23, and extends into the dehumidification equipment compartment 4; the hot end of the TEC cooling chip 6 is connected to the heat-conducting component 24, and extends into the dehumidification equipment compartment 4.

[0157] The dehumidification equipment compartment 4 is provided with an air inlet 40 on its side; the bottom plate of the storage dehumidification compartment 1 is also provided with a heat dissipation window 25, and the heat on the heat-conducting component 24 is blown out from the heat dissipation window 25 through the fan 23, so as to realize the air intake on the inner side and the air exhaust at the bottom of the dehumidification equipment compartment 4, thereby improving the heat dissipation effect of the refrigeration and dehumidification structure 5.

[0158] Furthermore, to ensure dehumidification effectiveness, the refrigeration and dehumidification structure 5 is configured in two sets, respectively positioned on both sides of the width of the dehumidification equipment compartment 4. Dehumidification is achieved through the aforementioned TEC cooling element 6, allowing the refrigeration and dehumidification structure 5 to be located within the width range of the dehumidification equipment compartment 4 as viewed from above.

[0159] like Figure 4 The diagram shows the internal structure of the storage dehumidification chamber. To optimize the spatial layout, space is reserved for the refrigeration and dehumidification structure 5. A support plate 26 for forming the dehumidification equipment chamber 4 is provided below the storage dehumidification chamber 1; the support plate 26 is located at the front and rear of the storage dehumidification chamber 1. This allows space to be reserved for the refrigeration and dehumidification structure 5, which is then positioned on both sides of the width of the dehumidification equipment chamber 4.

[0160] In this embodiment, to reduce the impact of ambient humidity on the reagent cards and minimize the time the reagent cards are in contact with the external humid environment, the testing quality of the reagent cards is guaranteed. Simultaneously, pre-dispensing of the reagent card magazine 3 is implemented, shortening the dispensing response time and thus improving the equipment's testing efficiency.

[0161] See Figure 11 and Figure 12 , Figure 11 This diagram illustrates the relative positions of the storage space and the pre-dispensing space of the reagent card storage and dehumidification device in an embodiment of the present invention. Figure 11 A three-dimensional structural diagram of the scanning component in an embodiment of the present invention is shown.

[0162] The storage dehumidification chamber 1 includes: a storage space 35 for storing the reagent card magazine 3, and a pre-dispensing space 36 for the reagent card to be ejected from the reagent card magazine 3 and then enter; the pre-dispensing space 36 is used to temporarily store the reagent card.

[0163] In this embodiment, the storage space 35 is also provided with a scanning component 37 for reading the reagent card information; when the card pushing mechanism 27 pushes the reagent card to the preset arrival position, the card pushing mechanism 27 triggers the arrival position detection component 34, which in turn triggers the scanning component 37 to read the reagent card information.

[0164] like Figure 12 As shown, the scanning component 37 includes:

[0165] The scanning mechanism includes: a first scanning element 41 and a second scanning element 42; the first scanning element 41 is used to identify the information code on the reagent card cartridge 3; the second scanning element 42 is used to identify the information code on the reagent card; the scanning mechanism is driven to slide in the horizontal direction along the arrangement direction of the plurality of reagent card cartridges 3 to realize the detection of the reagent card cartridges 3 and the reagent cards at multiple different positions;

[0166] The scanning motion plate 43 has the first scanning element 41 and the second scanning element 42 respectively disposed on the upper and lower sides of the scanning motion plate 43, and the scanning direction of the first scanning element 41 and the second scanning element 42 is the vertical direction.

[0167] The guiding mechanism includes: a guide rod 44 arranged along the arrangement direction of the plurality of reagent card cartridges 3; both ends of the guide rod 44 are connected to the outer shell of the storage dehumidification chamber 1, and the scanning motion plate 43 is slidably disposed on the guide rod 44 under drive;

[0168] The driving mechanism includes a second drive motor 45 and an idler pulley 46 connected via a transmission belt; the second drive motor 45 drives the scanning motion plate 43 to slide via the transmission belt. In this embodiment, by fixing the first scanning element 41 and the second scanning element 42 together and driving them through a single driving mechanism, the detection of the reagent card magazine 3 and the reagent card at multiple different positions is achieved. This scanning structure effectively utilizes space and also achieves bidirectional detection with a single motor. Therefore, the above-mentioned scanning mechanism, which identifies the reagent card information code and the reagent card magazine information code through a single motor drive, has the advantages of simple structure and low cost.

[0169] In this embodiment, the storage space 35 is also provided with a magnetic suction component 38 and an IC card reader 39 corresponding to the reagent card cartridge 3; the magnetic suction component 38 is attracted and connected to the reagent card cartridge 3 to fix the reagent card cartridge 3; the IC card reader 39 is communicatively connected to the reagent card cartridge 3 to read the information of the reagent card cartridge 3.

[0170] Of course, the specific structure of the instrument sealing chamber 2 is not specifically limited in this embodiment. In other embodiments, the dehumidification chamber door 10 of the storage dehumidification chamber 1 is not located on the front housing 7. The operator needs to open the front housing 7 of the instrument sealing chamber 2 and the dehumidification chamber door 10 of the storage dehumidification chamber 1 in sequence in order to place and take out the reagent card cartridge 3 in the storage dehumidification chamber 1.

[0171] Of course, this embodiment does not specifically limit whether to set the above-mentioned sealing element at the outlet position, or the sealing element structure at the outlet position of the storage dehumidification chamber 1. In other embodiments, the outlet can also be sealed by a telescopic baffle.

[0172] Of course, in this embodiment, the driving component 15 that drives the sealing sheet 13 to achieve the sealing of the dehumidification chamber 1 and its push-card window 12 is not specifically limited. In other embodiments, the driving component 15 can also achieve dynamic sealing of the push-card window 12 through a sensor.

[0173] Of course, this embodiment does not specifically limit whether the aforementioned push-pin holes 14 and driving members 15 are provided at both ends of the sealing sheet 13. In other embodiments, the push-pin holes 14 are only provided at the card outlet position away from the storage dehumidification chamber 1. When the card pushing mechanism 27 pushes the card, the sealing sheet 13 opens, and the sealing sheet 13 closes after the push-pin member 28 of the card pushing mechanism 27 resets.

[0174] Of course, this embodiment does not specifically limit the sensor types of the initial position detection component 33 and the arrival position detection component 34. In other embodiments, the initial position detection component 33 and the arrival position detection component 34 may also be photoelectric sensors or other position sensors.

[0175] Of course, this embodiment does not specifically limit the number and driving method of the first drive motor 32. In other embodiments, each telescopic mechanism 29 is provided with an independent first drive motor 32 to drive the telescopic mechanism 29 to slide on the slider guide rail 31.

[0176] Of course, this embodiment does not specifically limit the number of refrigeration and dehumidification structures 5 or their placement. In other embodiments, there may be two or more refrigeration and dehumidification structures 5, placed on both sides and in the middle of the dehumidification equipment compartment 4 in the width direction. Alternatively, there may be only one refrigeration and dehumidification structure 5, placed in the middle of the dehumidification equipment compartment 4.

[0177] Of course, in this embodiment, the positions of the air inlet 40 and the heat dissipation window 25 of the dehumidification equipment compartment 4 are not specifically limited. In other embodiments, the heat dissipation window 25 can be set on one side of the dehumidification equipment compartment 4, and the air inlet 40 can be set on the other side of the dehumidification equipment compartment 4.

[0178] Of course, the specific structure of the scanning mechanism is not specifically limited in this embodiment. In other embodiments, the first scanning element 41 and the second scanning element 42 are driven by an independently set driving mechanism to complete the identification of the reagent card information code and the reagent card cartridge information code.

[0183] Dehumidification equipment compartment 4, such as Figure 2 As shown, the immunoassay analyzer in this invention is disposed below the storage dehumidification chamber 1 and stacked with the storage dehumidification chamber 1. Figure 13 As shown in Instrument B, it can effectively reduce the horizontal width of the workbench occupied by the reagent card storage dehumidification device and improve the utilization rate of instrument layout space;

[0184] Refrigeration and dehumidification structure 5, such as Figure 4The diagram shows the internal structure of the storage dehumidification chamber. The refrigeration and dehumidification structure 5 is located on the side of the dehumidification equipment chamber 4. The refrigeration and dehumidification structure 5 controls the humidity inside the storage dehumidification chamber 1 through a TEC cooling element 6. Because the refrigeration and dehumidification structure 5 is located on the side of the dehumidification equipment chamber 4 and uses the TEC cooling element 6 for dehumidification, this arrangement effectively reduces the lateral width of the workbench required by the refrigeration and dehumidification structure 5 while ensuring its dehumidification effect.
