Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical detection system and a card feeding device. Background Art

[0002] In the field of IVD (In Vitro Diagnosis), immunochromatography is a widely used technique for testing. This technique typically involves processing strip-shaped reagent cards, adding body fluids to the card, and then incubating and measuring. To process multiple cards simultaneously and ensure the stability of the incubation process, the cards are temporarily stored in a constant-temperature incubation tray for incubation. After the incubation reaction is complete, the cards are removed and measured.

[0003] In traditional technology, the card feeding method generally uses linear guides and a transport cart to transport the reagent card into the position of the incubation tray, or manually inserts the reagent card directly into the position of the incubation tray.

[0004] For the card entry method using a guide rail and a transport cart, the reagent card is inserted into the transport cart, which is then driven by a belt into the incubation tray under the guidance of the guide rail. Another mechanism then pushes the reagent card from the cart into the incubation tray. In total, two actions work together to achieve the entry of the reagent card into the incubation tray. This results in a relatively complex structure with multiple power components.

[0005] Furthermore, with manual card feeding, there's a chance that the reagent card won't be fully inserted into the incubation tray, with a portion remaining outside. When the tray rotates to the next position, the remaining portion of the reagent card will hinder its movement, causing the tray to become stuck, impacting usability and reducing reliability.

DETAILED DESCRIPTION

[0034] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] See Figures 1 to 5 , Figure 1 FIG. 1 shows a schematic structural diagram of a medical detection system according to an embodiment of the present invention. Figure 2 FIG. 1 shows a schematic diagram of the decomposed structure of a medical detection system according to an embodiment of the present invention. Figure 3 FIG2 is a schematic diagram showing the process of a card feeding device pushing a reagent card 30 into a storage position according to an embodiment of the present invention. Figure 4 Shown Figure 3 Schematic diagram of the enlarged structure at A, Figure 5A schematic structural diagram of a card feeding device according to an embodiment of the present invention is shown from one perspective. A card feeding device provided in an embodiment of the present application includes: a conveying channel body 10 and a first drive assembly 20. The conveying channel body 10 is provided with a channel 11 for conveying a reagent card 30. The outlet 111 of the channel 11 is used to connect with the bin feed port of the card dialing turntable 40. The first drive assembly 20 includes two first rotating members 21 rotatably arranged on opposite sides of the outlet 111. The first rotating member 21 includes a first rotating body 211 and a pushing portion 212 connected to the top of the first rotating body 211. The first rotating body 211 is used to be arranged in the notch 51 at the edge of the incubation tray 50, and the top surface of the first rotating body 211 is located below the top surface of the incubation tray 50 or flush with the top surface of the incubation tray 50. The pushing portion 212 is spaced apart from the central axis of the first rotating body 211. Specifically, the pushing portion 212 is located at the edge of the top surface of the first rotating body 211. The pushing portion 212 is used to protrude above the top surface of the incubation tray 50 and to contact the side wall of the reagent card 30 to push the reagent card 30 out of the channel 11 and into the storage position.

[0036] Above-mentioned card feeding device, after the pushing portion 212 of two first rotating members 21 respectively contacts with two relative side walls of reagent card 30, under the rotation of the first rotating body 211, two pushing portions 212 can provide thrust to make reagent card 30 move towards the position simultaneously.And because the first rotating body 211 is positioned at the breach 51 at incubation dish 50 edge, also namely two pushing portions 212 can make reagent card 30 enter in the position fully.In addition, after reagent card 30 enters in the position fully, the first rotating body 211 rotates and makes pushing portion 212 rotate to the limit position away from incubation dish 50 center, and because the top surface of the first rotating body 211 is positioned at the below of incubation dish 50 top surfaces or is flush with the top surface of incubation dish 50, can guarantee like this that dialing card turntable 40 drives the reagent card 30 on incubation dish 50 top surfaces and operates normally.As can be seen, there is no need to manually operate to complete card feeding, and work efficiency is higher, and reliability improves, and structure is simple simultaneously, and cost is low.

[0037] See also Figures 4 to 6 , Figure 6 A schematic diagram of the exploded structure of a card feeder according to one embodiment of the present invention is shown. In one embodiment, the sidewalls of the pusher 212, distal from the central axis of the first rotating body 211, are configured as curved walls 2121. This allows the two pushers 212 to rotate, contacting the two opposing sidewalls of the reagent card 30 via the two curved walls 2121. This ensures a more stable force on the two opposing sidewalls of the reagent card 30, enabling the reagent card 30 to be stably pushed into the storage compartment with minimal damage.

[0038] See also Figures 4 to 6In one embodiment, the pushing portion 212 is arranged on the top edge of the first rotating body 211. In this way, when the reagent card 30 is completely entered into the warehouse, the first rotating body 211 rotates to rotate the pushing portion 212 to a position away from the center of the incubation tray 50. It can ensure as much as possible that the card dial 40 will not interfere with the pushing portion 212 during the rotation of the reagent card 30 on the incubation tray 50.

[0039] See also Figure 4 and Figure 5 In one embodiment, a side wall of the pushing portion 212 facing the central axis of the first rotating body 211 is configured as a flat surface 2122 .

[0040] It should be noted that the "pushing part 212" can be "a part of the first rotating body 211", that is, the "pushing part 212" and the "other parts of the first rotating body 211" are manufactured as one piece, for example, the pushing part 212 is obtained by milling on the top of the first rotating body 211; it can also be an independent component that can be separated from the "other parts of the first rotating body 211", that is, the "pushing part 212" can be manufactured independently and then combined with the "other parts of the first rotating body 211" into a whole.

[0041] Optionally, the axial cross-section of the first rotating body 211 is, for example, circular, elliptical, polygonal or other regular and irregular shapes, which can be specifically set according to actual needs.

[0042] In one embodiment, an elastic layer is further provided on the sidewall of the pushing portion 212 away from the central axis of the first rotating body 211, or the pushing portion 212 is configured as an elastic portion. Optionally, the elastic layer includes, but is not limited to, rubber, elastic plastic, sponge, latex, etc. Thus, the provision of the elastic layer can prevent damage to the reagent card 30 and facilitate stable clamping of the reagent card 30.

[0043] See also Figures 4 to 6 In one embodiment, when the two pushing portions 212 rotate to a position where they contact opposing side walls of the reagent card 30, the distance between the walls of the two pushing portions 212 and the reagent card 30 is less than the width of the reagent card 30, that is, the distance between its opposing side walls. In this manner, the two pushing portions 212 of the first drive assembly 20 respectively contact the side walls of the reagent card 30, thereby clamping the opposing side walls of the reagent card 30 and ensuring that the reagent card 30 is smoothly pushed into the storage compartment.

[0044] See also Figures 4 to 6In one embodiment, the first drive assembly 20 further comprises a first motor 22 and a first gear 23 coaxially connected to the rotating shaft of the first motor 22. The first rotating member 21 further comprises a second gear 24 coaxially connected to the first rotating body 211. The two second gears 24 mesh with each other, wherein one of the second gears 24 meshes with the first gear 23. In this way, when the first motor 22 drives the first gear 23 to rotate, the first gear 23 drives the second gear 24 to rotate, and the second gear 24 drives the other second gear 24 to rotate synchronously. The two second gears 24 synchronously drive the two first rotating bodies 211 in opposite directions at the same speed, so that the two pushing parts 212 contact the two relative side walls of the reagent card 30 together, providing the reagent card 30 with a forward or backward transmission force and no slipping. In addition, since the reagent card 30 both sides have the same power, there is almost no relative sliding when the reagent card 30 and the pushing part 212 contact, which can ensure that the wear is small and the reliability is high. In addition, the two first rotating members 21 share one first motor 22, which simplifies the structure and is low in cost.

[0045] Of course, in some optional schemes, the first motor 22 is not limited to one, but can be flexibly set to a larger number according to actual needs, for example, two first motors 22 correspond to the two first rotating members 21, and respectively drive the two first rotating members 21 to rotate. In addition, the first motor 22 can also be set to other numbers.

[0046] See also Figures 4 to 7 , Figure 7A schematic cross-sectional view of a card feeder device according to an embodiment of the present invention is shown. In one embodiment, the card feeder device further comprises a bracket 60. The conveying channel body 10 and the first motor 22 are both connected to the bracket 60. The first rotating body 211 is rotatably connected to the bracket 60. The card feeder device further comprises a second drive assembly 70, which includes two second rotating members 71 rotatably connected to opposite sides of the conveying channel body 10. The second rotating member 71 includes a second rotating body 711 rotatably connected to the bracket 60, a third gear 712 connected to the second rotating body 711, and a drive wheel 713 connected to the second rotating body 711. A window 12 is provided on the side wall of the conveying channel body 10, which is connected to the channel 11. The wheel surface of the drive wheel 713 extends through the window 12 into the channel 11 to abut against the side wall of the reagent card 30. The first gear 23 also meshes with one of the third gears 712, and the two third gears 712 mesh with each other. In this way, the two driving wheels 713 respectively extend through the window 12 into the channel 11 and respectively abut against two opposite side walls of the reagent card 30 to clamp the reagent card 30. In addition, during the operation of the first motor 22, it not only drives the two first rotating members 21 to rotate synchronously, but also drives the two second rotating members 71 to rotate synchronously. When the two second rotating members 71 rotate synchronously, the two driving wheels 713 rotate synchronously, and the two driving wheels 713 can push the reagent card 30 in the channel 11 toward the incubation tray 50.

[0047] See also Figures 4 to 7 In one embodiment, the number of second drive assemblies 70 is not limited to one; for example, two or more second drive assemblies 70 may be provided. The two or more second drive assemblies 70 are sequentially spaced along the extension direction of the channel 11. A third gear 712 of the second drive assembly 70 adjacent to the first drive assembly 20 meshes with the first gear 23. Two adjacent second drive assemblies 70 are provided with transition wheels 13. The transition wheels 13 are rotatably connected to the bracket 60 and mesh with the third gears 712 of the two second drive assemblies 70 located on the same side of the channel 11. This ensures that the third gears 712 of the two or more second drive assemblies 70 and the second gear 24 of the first drive assembly 20 rotate synchronously in the same direction and at the same speed, thereby ensuring that the reagent card 30 in the channel 11 is stably pushed out of the channel 11. Furthermore, in this embodiment, the reagent card 30 is driven to move within the channel 11 by clamping the sidewall of the reagent card 30 until it enters the storage compartment, preventing contact with the detection surface of the reagent card 30 and preventing biological contamination.

[0048] See also Figures 4 to 7In one embodiment, to ensure smooth transmission of the reagent card 30, the longitudinal distance between two adjacent driving wheels 713 located on the same side of the channel 11 is smaller than the length of the reagent card 30. In this way, in the transmission direction of the reagent card 30, there is always a pair of driving wheels 713 clamping and driving the reagent card 30 to move forward, thereby ensuring stable transmission.

[0049] See also Figures 4 to 7 In one embodiment, the channel 11 is a chute formed on the conveying channel body 10. The card feeding device further includes a stopper 14 connected to the conveying channel body 10 and disposed at the notch of the chute. As the reagent card 30 moves along the chute, the stopper 14 engages with the top surface of the reagent card 30 within the chute, vertically limiting the reagent card 30 and preventing it from dislodging upward from the chute when squeezed by the drive wheel 713. This ensures stable forward conveyance of the reagent card 30 along the channel 11.

[0050] Optionally, the limiting member 14 can be flexibly configured as a limiting structure such as a limiting plate, an elastic pressing piece, a limiting rod, etc. according to actual needs.

[0051] It should be noted that the "limiting member 14" can be a "part of the conveying channel main body 10", that is, the "limiting member 14" and the "other parts of the conveying channel main body 10" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the conveying channel main body 10", that is, the "limiting member 14" can be manufactured independently and then combined with the "other parts of the conveying channel main body 10" into a whole.

[0052] See also Figures 4 to 7 In one embodiment, the stopper 14 is provided with a hollow opening 141 communicating with the channel 11, or the stopper 14 is configured as a transparent member. In this way, the stopper 14 not only vertically limits the position of the reagent card 30 in the channel 11, but also facilitates observation of the running position of the reagent card 30 in the channel 11.

[0053] See also Figures 4 to 7 In one embodiment, the limiting member 14 is a limiting plate. A guide portion 142 is provided at one end of the limiting plate, located near the entrance 112 of the channel 11, and arranged at an angle to the direction in which the channel 11 extends. This allows the limiting plate to limit the position of the reagent card 30 when in contact with the top surface of the reagent card 30 while also exerting minimal friction, ensuring stable and smooth forward movement of the reagent card 30. Furthermore, the guide portion 142 provides guidance as the reagent card 30 enters the channel 11 through the entrance 112, facilitating its entry into the channel 11.

[0054] See also Figures 4 to 6In one embodiment, the card feeding device further includes a controller (not shown) and a first position sensor 81. The controller is electrically connected to the first position sensor 81 and the first driving assembly 20. The first position sensor 81 is used to sense whether the pushing portion 212 is rotated to the extreme position away from the center of the incubation tray 50 (e.g., Figure 5 The controller is used to control the first rotating body 211 to stop rotating after the reagent card 30 has completely entered the storage position and the pushing portion 212 has rotated to the extreme position away from the center of the incubation tray 50. In this way, when the reagent card 30 has completely entered the storage position and the pushing portion 212 has rotated to the extreme position away from the center of the incubation tray 50, it can be detected in time by the first position sensor 81, and the first rotating body 211 is controlled to stop rotating based on the detection signal of the first position sensor 81, so that the pushing portion 212 is located at the extreme position away from the center of the incubation tray 50, that is, no manual operation is required, the degree of automation is high, and the reliability and work efficiency are improved.

[0055] Specifically, the controller is electrically connected to the first motor 22. When the reagent card 30 is completely inserted into the storage position and the pusher 212 rotates to a limit position away from the center of the incubation tray 50, the first motor 22 is controlled to stop.

[0056] See also Figure 5 and Figure 6 Specifically, a mounting plate 84 is connected to one of the first rotating bodies 211. The mounting plate 84 has a sensing mating portion 841 that cooperates with the first position sensor 81. The first position sensor 81 is connected to the bracket 60. When the pusher 212 rotates to the extreme position away from the center of the incubation tray 50, the sensing mating portion 841 rotates to a position sensed by the first position sensor 81. In this way, the first position sensor 81 determines whether the pusher 212 has rotated to the extreme position away from the center of the incubation tray 50 by detecting the position of the sensing mating portion 841.

[0057] Optionally, the first position sensor 81 includes but is not limited to a proximity switch, an optical coupler sensor, an RFID (Radio Frequency Identification) sensor, a magnetic sensor, a laser rangefinder, an ultrasonic rangefinder, etc., and can be flexibly adjusted and set according to actual needs.

[0058] See also Figures 5 to 7In one embodiment, the card feeder further includes a controller, a second position sensor 82, and a third position sensor 83. The controller is electrically connected to the second position sensor 82 and the third position sensor 83. The second position sensor 82 is disposed at the entrance 112 of the passage 11, and the third position sensor 83 is disposed in the middle portion of the passage 11 or at the exit 111. In this way, when the reagent card 30 enters the channel 11 through the entrance 112, the second position sensor 82 can sense the entry of the reagent card 30, generate a first sensing signal of the reagent card 30 entering, and send the first sensing signal to the controller. The controller controls the first motor 22 to work according to the first sensing signal, so that the reagent card 30 enters the channel 11 under the drive of the driving wheel 713; after the reagent card 30 enters the channel 11, it will be sensed by the third position sensor 83. When the reagent card 30 leaves the third position sensor 83, a second sensing signal is generated. The controller can calculate the position of the reagent card 30 according to the second sensing signal, and control the first motor 22 to continue running for a preset time and then stop running, so that the reagent card 30 can be completely pushed into the warehouse.

[0059] Among them, the preset time is calculated based on parameters such as the length of the reagent card 30, the distance between the position of the third position sensor 83 and the reagent card 30 when it is fully entered into the warehouse, and the rotation speed of the first motor 22. The preset time needs to be set long enough to be able to push the reagent card 30 completely into the warehouse.

[0060] See also Figures 1 to 5 In one embodiment, a medical detection system is provided, the medical detection system includes the card feeding device of any of the above embodiments, and the medical detection system further includes: an incubation tray 50 and a card dialing turntable 40. A notch 51 is provided on the edge of the incubation tray 50, and the first rotating body 211 is provided in the notch 51, and the top surface of the first rotating body 211 is located below the top surface of the incubation tray 50 or flush with the top surface of the incubation tray 50, and the pushing portion 212 protrudes above the top surface of the incubation tray 50. The card dialing turntable 40 is rotatably connected to the top of the incubation tray 50, and the card dialing turntable 40 is provided with a bin extending along its radial direction, and the outlet 111 of the channel 11 is connected to the feed port of the bin.

[0061] Above-mentioned medical detection system, after the pushing portion 212 of two first rotating members 21 contacted each other with two relative side walls of reagent card 30 respectively, under the rotation of the first rotating body 211, two pushing portions 212 can provide thrust simultaneously and reagent card 30 moves towards the position.And because the first rotating body 211 is positioned at the breach 51 at incubation dish 50 edges, also namely two pushing portions 212 can make reagent card 30 enter in the position fully.In addition, after reagent card 30 enters in the position fully, the first rotating body 211 rotates and makes pushing portion 212 rotate to the limit position away from incubation dish 50 centers, and because the top surface of the first rotating body 211 is positioned at the below of incubation dish 50 top surfaces or is flush with the top surface of incubation dish 50, can guarantee like this that dialing card turntable 40 drives the reagent card 30 on incubation dish 50 top surfaces and operates normally.As can be seen, there is no need to manually operate to complete card feeding, and work efficiency is higher, and reliability improves, and structure is simple simultaneously, and cost is low.

[0062] In one embodiment, there are multiple storage locations, which are spaced apart on the card dialing turntable 40. The storage locations are receiving slots formed on the bottom surface of the card dialing turntable 40, with the notches of the receiving slots facing the top surface of the incubation tray 50. The top surface of the incubation tray 50 is used to support the reagent card 30. In this way, since the top surface of the incubation tray 50 supports the reagent card 30, that is, directly contacts the reagent card 30, heat can be better transferred to the reagent card 30, which can improve heat transfer efficiency.

[0063] See also Figures 1 to 3 In one embodiment, a plurality of mating teeth 41 are provided on the circumferential outer edge of the card dial 40. The medical detection system further includes a second motor 91 and a fourth gear 92 coaxially connected to the shaft of the second motor 91. The fourth gear 92 meshes with the mating teeth 41.

[0064] See also Figures 1 to 3 In one embodiment, the medical testing system further includes a heat-insulating cover 93 disposed above the card dialing turntable 40. Thus, the card dialing turntable 40 acts like a lid over the incubation tray 50, forming a first layer of constant temperature protection. The heat-insulating cover 93 is added to the card dialing turntable 40 to form a second layer of constant temperature protection.

[0065] In one embodiment, the medical detection system further includes at least one first support rod 94 and / or at least one second support rod 95. The first support rod 94 is connected to the incubation tray 50. The second support rod 95 is connected to the heat preservation cover 93.

[0066] Specifically, there are a plurality of first support rods 94, and the plurality of first support rods 94 are arranged at equal intervals. In addition, there are a plurality of second support rods 95, and the plurality of second support rods 95 are arranged at equal intervals.

[0067] In one embodiment, a fourth position sensor for detecting the zero position of the card dial 40 and a fifth position sensor for detecting the position of the card dial 40 are provided on the heat-insulating cover 93. Optionally, the fourth position sensor is used to detect a flange on the card dial 40 to position the card dial 40. Similarly, the fifth position sensor is used to detect the flange on the card dial 40 to count.

[0068] In one embodiment, in order to ensure the heating effect of the incubation tray 50, a heating film 96 is provided at the bottom of the incubation tray 50. The heating device transfers heat to the incubation tray 50 through the heating film 96, which can ensure the uniformity of the temperature of each part of the incubation tray 50.

[0069] See also Figure 1 and Figure 2 In one embodiment, the medical detection system further includes a first support seat 97 and an elastic member 98. The second motor 91 can be floatingly arranged on the first support seat 97 in a direction away from or close to the card dial 40. The second motor 91 is connected to the first support seat 97 through the elastic member 98, and the elastic member 98 is used to press the fourth gear 92 against the mating tooth 41. In this way, on the one hand, under the action of the elastic member 98, the fourth gear 92 is tightly engaged with the mating tooth 41 to ensure stable meshing. When the rotating shaft of the second motor 91 rotates, the rotating shaft of the second motor 91 drives the fourth gear 92 to rotate synchronously, and the fourth gear 92 synchronously drives the mating tooth 41 to move, so that the card dial 40 can rotate freely and flexibly. On the other hand, when insufficient machining precision of the mating teeth 41 of the dial 40 causes a jam with the fourth gear 92, the second motor 91 and mounting bracket will swing outward, skipping over the meshing teeth. This resolves the issue of insufficient machining precision of the mating teeth 41 of the dial 40 during manufacturing and prevents damage to the mating teeth 41 after jamming. It automatically adapts to machining and assembly errors of the dial 40, effectively avoiding transmission overload and effectively protecting the fourth gear 92 from breakage in the event of an accident. Furthermore, compared to traditional drive methods, the torque required to drive the dial 40 is smaller, resulting in more accurate positioning. Furthermore, the smaller second motor 91 and external corner layout occupy less space and are more compact.

[0070] See also Figure 1 and Figure 2In one embodiment, a second support seat 931 is provided at the edge of the heat-insulating cover 93. The first support seat 97 and the second support seat 931 are detachably connected. The first support seat 97 and the second support seat 931 enclose a chamber, and the fourth gear 92 is movably arranged in the chamber, and the second support seat 931 is also provided with a movable opening connected to the chamber, and the mating tooth 41 extends into the chamber through the movable opening. In this way, on the one hand, since the first support seat 97 and the second support seat 931 are detachably connected, the drive assembly can be easily replaced and maintained; on the other hand, since the first support seat 97 and the second support seat 931 enclose a chamber, the fourth gear 92 is arranged inside the chamber to avoid being exposed, thereby protecting the fourth gear 92.
