DETAILED DESCRIPTION

[0059] To make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and claimed herein. It is therefore intended that the present application not be limited in scope to the specific embodiments disclosed but rather that the scope of the present application be measured by the broadest permissible interpretation of the claims.

[0060] Reference is made to Figure 1 , Figure 10 , Figure 14 , and Figure 18 , Figure 1 shows an exploded structural schematic view of a medical detection device in an embodiment of the present application, Figure 1 is hidden in the card feeding device 40, the fluorescence detection device 60 and the card ejection mechanism 70. Figure 10 shows a structural schematic view of the card ejection mechanism 70 in an embodiment of the present application. Figure 14 shows an exploded structural schematic view of the card feeding device 40 in an embodiment of the present application. Figure 18A structure diagram of the fluorescence detection device 60 is shown. The medical detection equipment provided by the embodiment of the present application comprises an incubation tray 10, a card dialing tray 20, a first driving mechanism 30, a card feeding device 40, a temperature rising and falling mechanism 50, a fluorescence detection device 60 and a card discharging mechanism 70. The incubation tray 10 is provided with a top surface 11 for supporting a reagent card 80. The card dialing tray 20 is rotatably connected with the incubation tray 10 and located above the incubation tray 10. The card dialing tray 20 is provided with a plurality of accommodating grooves 21 which are arranged at intervals and used for accommodating the reagent card 80. An opening 22 is arranged at an end of the accommodating groove 21 away from the center of the card dialing tray 20 and used for loading or taking out the reagent card 80. The first driving mechanism 30 is connected with the card dialing tray 20 and used for driving the card dialing tray 20 to rotate. The card feeding device 40 is arranged adjacent to the incubation tray 10 and used for enabling the reagent card 80 to enter the accommodating groove 21 through the opening 22. The temperature rising and falling mechanism 50 is connected with the incubation tray 10 and used for transferring heat or cold to the incubation tray 10 so as to control the temperature of the incubation tray 10 to be within a preset range. The light path assembly of the fluorescence detection device 60 is used for facing the reagent card 80 so as to detect the reagent card. The card discharging mechanism 70 is used for pushing the reagent card 80 in the accommodating groove 21 out of the accommodating groove 21 through the opening 22.

[0061] In the working process of the medical detection equipment, the first driving mechanism 30 drives the card dialing tray 20 to rotate, so that the opening 22 of the accommodating groove 21 stops rotating at the card feeding position, that is, the opening 22 is opposite to the card feeding device 40. The card feeding device 40 feeds the reagent card 80 into the accommodating groove 21 through the opening 22. Since the accommodating grooves 21 are a plurality of grooves and are matched with the rotation of the card dialing tray 20, the plurality of reagent cards 80 can be sequentially fed into the plurality of accommodating grooves 21. The temperature rising and falling mechanism 50 controls the temperature of the incubation tray 10 to be within a preset range by heating or cooling the incubation tray 10, so as to play an incubation role. Under the driving of the first driving mechanism 30, the card dialing tray 20 moves the reagent card 80 whose incubation is completed to the incubation tray outlet position. The card discharging mechanism 70 pushes the reagent card 80 to be detected into the fluorescence detection device 60. At the same time, the reagent card to be detected kicks the reagent card whose detection is completed out of the fluorescence detection device 60 and then falls into the reagent card recycling box. The light path assembly 63 of the fluorescence detection device 60 faces the reagent card 80, so as to detect the reagent card. Therefore, the medical detection equipment has a higher automation degree, is convenient to operate, has a relatively simple overall structure, is rationally arranged and is stable and reliable in operation.

[0062] Please refer to Figure 2 and Figure 3 , Figure 2 A structure diagram of the reagent card 80 accommodated in the card dialing tray 20 is shown, Figure 3 A structure diagram of the reagent card 80 accommodated in the card dialing tray 20 is shown, Figure 2The enlarged structural schematic diagram of A. In one embodiment, the groove wall of the accommodating groove 21 is provided with an elastic clamping piece 23, which is used for clamping cooperation with the groove 81 of the reagent card 80. In this way, a plurality of reagent cards 80 are respectively loaded into a plurality of accommodating grooves 21, and the clamping force provided by the elastic clamping piece 23 can overcome the centrifugal force of the reagent card 80 during the rotation of the card dial 20, so as to prevent the reagent card 80 from being thrown outwards through the opening 22 during the rotation of the card dial 20, and to ensure that the reagent card 80 is stably in the accommodating groove 21 during the rotation, thereby greatly reducing the failure rate. In addition, the elastic clamping piece 23 can be deformed due to stress, so that the reagent card 80 can be smoothly loaded when being pushed into the accommodating groove 21 through the opening 22. After the reagent card 80 is loaded, the elastic clamping piece 23 is correspondingly clamped into the groove 81 of the reagent card 80 to limit the reagent card 80. Similarly, when the reagent card 80 in the accommodating groove 21 is taken out, the taking-out force of the reagent card 80 is greater than the resistance of the elastic clamping piece 23 to the reagent card 80, so that the reagent card 80 can be smoothly taken out from the card dial 20.

[0063] Please refer to Figures 1 to 3 In one embodiment, one side wall of the accommodating groove 21 is provided with a first avoiding part 211, and the elastic clamping piece 23 is arranged at the first avoiding part 211. In this way, when the reagent card 80 is loaded or taken out, the elastic clamping piece 23 can move to the first avoiding part 211 and be separated from the groove 81 of the reagent card 80 when receiving a larger pushing and pulling force, so that the card loading and taking-out operations can be smoothly completed.

[0064] Please refer to Figure 3 In one embodiment, the first avoiding part 211 is, for example, a first recess formed on the side wall of the accommodating groove 21 or a through hole penetrating through the side wall of the accommodating groove 21. In addition, the elastic clamping piece 23 includes an elastic arm 231 located in the first avoiding part 211 and connected with the wall of the first avoiding part 211, and a first protruding part 232 connected with the elastic arm 231. One side surface of the elastic arm 231 in a natural state is flush with the groove wall of the accommodating groove 21, and the first protruding part 232 is used for clamping cooperation with the groove 81 of the reagent card 80. In this way, since one side surface of the elastic arm 231 in the natural state is flush with the groove wall of the accommodating groove 21, the side surface of the elastic arm 231 does not interfere with the reagent card 80 during the loading and taking-out of the reagent card 80, so as to ensure that the reagent card 80 can be smoothly loaded and taken out.

[0065] In the natural state, the reagent card 80 is not loaded in the accommodating groove 21.

[0066] In the natural state, one side of the elastic arm 231 is flush with the wall of the accommodating groove 21, that is, the distance between one side of the elastic arm 231 in the natural state and the central axis of the accommodating groove 21 (as shown by Z in Figure 3 ) is equal to the distance between the wall of the accommodating groove 21 and the central axis of the accommodating groove 21.

[0067] Of course, as an optional solution, the distance between one side of the elastic arm 231 in the natural state and the central axis of the accommodating groove 21 is greater than the distance between the wall of the accommodating groove 21 and the central axis of the accommodating groove 21. In other words, the elastic arm 231 is completely arranged in the first avoiding portion 211, and at this time, it is only necessary to ensure that the first protruding portion 232 protrudes from the wall of the accommodating groove 21.

[0068] Referring to Figure 3 , in an embodiment, the first protruding portion 232 is, for example, an arc-shaped portion. In this way, when the pushing and pulling force on the reagent card 80 is greater than the resistance of the elastic clamping member 23 to the reagent card 80 during the card loading and unloading process, the reagent card 80 can move past the surface of the arc-shaped portion and naturally press the first protruding portion 232 to deform the elastic clamping member 23 and move it into the first avoiding portion 211, thereby smoothly completing the card loading and unloading action, avoiding the defect that the reagent card 80 is stuck in the accommodating groove 21, and avoiding causing a large noise during the card loading and unloading process.

[0069] Referring to Figure 3 , the first protruding portion 232 is provided with a first inclined surface and a second inclined surface connected to each other and arranged at an angle along the length direction of the accommodating groove 21. In this way, when the pushing and pulling force on the reagent card 80 is greater than the resistance of the elastic clamping member 23 to the reagent card 80 during the card loading and unloading process, the reagent card 80 can move past the first inclined surface and the second inclined surface and naturally press the first protruding portion 232 to deform the elastic clamping member 23 and move it into the first avoiding portion 211, thereby smoothly completing the card loading and unloading action, avoiding the defect that the reagent card 80 is stuck in the accommodating groove 21, and avoiding causing a large noise during the card loading and unloading process.

[0070] In the length direction of the accommodating groove 21, it refers to the direction in which one end of the accommodating groove 21 extends to the other end, that is, the same direction as the central axis Z as shown in Figure 3 .

[0071] In an embodiment, one end of the elastic clamping member 23 is connected to the wall of the first avoiding portion 211, and the other end of the elastic clamping member 23 is a free end.

[0072] In an embodiment, the distance between the two opposite walls of the opening 22 (as shown by L in Figure 3As shown in Figure S, the opening 22 decreases in the direction in which the reagent card 80 is inserted into the receiving groove 21. In this way, the opening wall of the opening 22 acts as a guide, making it easy for the reagent card 80 to be inserted into the receiving groove 21 through the opening 22.

[0073] Please refer to the following: Figures 1 to 3 In one embodiment, a plurality of positioning blocks 24 are spaced apart on the bottom wall surface of the card dial 20 in the circumferential direction. The positioning blocks 24 are arranged radially along the card dial 20, and two adjacent positioning blocks 24 form a receiving groove 21.

[0074] Since the positioning block 24 is arranged along the circumferential direction of the bottom wall of the card dial 20, the resulting receiving groove 21 is also arranged along the radial direction of the card dial 20. Furthermore, specifically, the receiving grooves 21 are arranged at equal intervals.

[0075] Please see Figure 1 , Figures 4 to 6 In one embodiment, the card-dispensing turntable 20 has a plurality of mating teeth 25 on its circumferential outer edge. The first drive mechanism 30 includes a first motor 33 and a gear 34 coaxially connected to the shaft of the first motor 33. The mating teeth 25 mesh with the gear 34. Thus, when the shaft of the first motor 33 rotates, it drives the gear 34 to rotate, and when the gear 34 rotates, it correspondingly drives the mating teeth 25 to move, thereby driving the card-dispensing turntable 20 to rotate on the incubation tray 10. In addition, this design can both amplify the transmission of force and reduce the installation area and related limitations of traditional intermediate drives.

[0076] Please see Figure 1 , Figures 4 to 6In one embodiment, the first drive mechanism 30 further includes a first support base 31, a mounting base 32, and a first elastic element 35. The mounting base 32 is rotatably connected to the first support base 31. The position of the axis of rotation of the first motor 33 is different from the position of the axis of rotation of the mounting base 32. The mounting base 32 is also connected to the first support base 31 through the first elastic element 35, which provides elastic force to make the gear 34 mesh tightly with the mating gear 25. Thus, since the mounting base 32 is connected to the first support base 31 through the first elastic element 35, and the mounting base 32 is rotatably connected to the first support base 31, and the position of the axis of rotation of the first motor 33 is different from the position of the axis of rotation of the mounting base 32, on the one hand, the gear 34 and the mating gear 25 are tightly meshed under the action of the first elastic element 35, ensuring stable meshing; on the other hand, when the axis of rotation of the first motor 33 rotates, the axis of rotation of the first motor 33 drives the gear 34 to rotate synchronously, and the gear 34 drives the mating gear 25 to move synchronously, so that the card dial 20 can rotate freely and flexibly. On the other hand, when the mating teeth 25 of the card dial 20 jam with the gear 34 due to insufficient machining precision, the first motor 33 and the mounting base 32 will swing outwards, skipping the meshing teeth. This solves the problem of insufficient machining precision of the mating teeth 25 of the card dial 20 during manufacturing and prevents damage to the mating teeth 25 after jamming. It automatically adapts to the machining and assembly errors of the card dial 20, effectively avoiding transmission overload and effectively protecting the gear 34 from breakage in case of an accident. In addition, compared with the traditional drive method, the torque required to drive the card dial 20 is smaller and the positioning is more accurate. Furthermore, the smaller first motor 33 and the external corner layout occupy less space and are more compact.

[0077] It should be noted that the elastic force of the first elastic element 35 needs to be designed reasonably so that it can ensure reliable transmission and prevent the teeth from skipping when the incubation tray 10 stops.

[0078] In one embodiment, the mounting base 32 may include, but is not limited to, a plate. Furthermore, the top surface 11 of the first support base 31 is a plane, and the mounting base 32 is attached to the first support base 31 and swings around its rotation axis, resulting in good stability.

[0079] Please see Figure 1 , Figures 4 to 6 In one embodiment, the first support 31 is provided with at least one limiting member 311. The limiting member 311 abuts against the mounting base 32. Thus, when the limiting member 311 abuts against the mounting base 32, it can limit the continued swinging of the mounting base 32, so that the swing amplitude of the gear 34 driven by the mounting base 32 is appropriate. This ensures that the gear 34 and the mating teeth 25 are tightly engaged, ensuring transmission stability; on the other hand, it ensures that the gear skipping function can be guaranteed in the event of jamming.

[0080] Specifically, the two limiting members 311 are respectively located at opposite sides of the mounting seat 32, so that the mounting seat 32 swings within the range defined by the two limiting members 311.

[0081] Referring to Figure 1 , Figures 4 to 6 , in an embodiment, a second recess 321 is arranged on the side wall of the mounting seat 32, and the second recess 321 is arranged in position corresponding to the limiting member 311. In this way, when the mounting seat 32 swings to abut against the limiting member 311, the limiting member 311 is in the second recess 321, and the second recess 321 limits the limiting member 311, so that the limiting member 311 has better limiting stability for the mounting seat 32.

[0082] Specifically, the cross section of the limiting member 311 can be flexibly set and adjusted according to actual needs, for example, including but not limited to regular shapes such as a circle, an ellipse, a polygon, and irregular shapes.

[0083] Referring to Figure 1 , Figures 4 to 6 , in an embodiment, the first support seat 31 is provided with a movable hole 313, and the rotating shaft of the first motor 33 movably penetrates the movable hole 313. When the gear 34 and the cooperating teeth 25 have a tooth skipping phenomenon, the mounting seat 32 swings relative to the first support seat 31, and the mounting seat 32 drives the first motor 33 to swing, and the rotating shaft of the first motor 33 can move along the movable hole 313, so that the stability is better.

[0084] Referring to Figure 1 , Figures 4 to 6 , in an embodiment, the first support seat 31 is provided with a first connecting portion 312, and the mounting seat 32 is provided with a second connecting portion 322. The two ends of the first elastic member 35 are respectively connected to the first connecting portion 312 and the second connecting portion 322.

[0085] Optionally, the first elastic member 35 includes but is not limited to a spring, a spring sheet, rubber, or other elastic elements flexibly adjusted and set according to actual needs, which are not limited herein.

[0086] Referring to Figure 5 , Figure 6 , in an embodiment, the mounting seat 32 is provided with a connecting shaft 36, the first support seat 31 is provided with a bearing 37, and the connecting shaft 36 is rotatably arranged in the bearing 37, so that the mounting seat 32 stably rotates on the first support seat 31, thereby driving the first motor 33 to stably swing, and the swing trajectory of the first motor 33 is a circle shown by a dashed line in Figure 1 or Figures 4 to 6 .

[0087] Referring to Figure 1 , Figures 4 to 6 In one embodiment, the medical detection device further comprises a heat preservation cover 91 arranged above the card dial 20. The first support seat 31 is connected with the heat preservation cover 91 or the incubation tray 10. In this way, the card dial 20 is similar to a cover buckled above the incubation tray 10, forming a first layer of constant temperature protection. The heat preservation cover 91 is arranged on the card dial 20, forming a second layer of constant temperature protection.

[0088] In addition, specifically, the periphery and the bottom of the lower incubation tray 10 are pasted with heat preservation materials, and the openings 22 are provided with relevant sealing measures, so as to maximize the constant temperature performance of the incubation module. The heat preservation materials include but are not limited to heat preservation cotton or polyurethane, etc.

[0089] Referring to Figure 7 , Figure 1 In one embodiment, the edge of the heat preservation cover 91 is provided with a second support seat 911. The first support seat 31 is detachably connected with the second support seat 911. The first support seat 31 and the second support seat 911 enclose a cavity, the gear 34 is movably arranged in the cavity, and the second support seat 911 is further provided with a first avoiding opening in communication with the cavity, and the gear 25 extends into the cavity through the first avoiding opening. In this way, on the one hand, since the first support seat 31 is detachably connected with the second support seat 911, the driving assembly can be conveniently replaced and maintained; on the other hand, since the first support seat 31 and the second support seat 911 enclose the cavity, the gear 34 is arranged inside the cavity and avoids being exposed, thereby playing a protective role on the gear 34.

[0090] Referring to Figure 1 In one embodiment, the medical detection device further comprises at least one first support rod 921 and / or at least one second support rod 922. The first support rod 921 is connected with the incubation tray 10. The second support rod 922 is connected with the heat preservation cover 91.

[0091] Specifically, the first support rod 921 is a plurality of first support rods 921 arranged at equal intervals. In addition, the second support rod 922 is a plurality of second support rods 922 arranged at equal intervals.

[0092] Referring to Figures 14 to 17 In one embodiment, a first sensor 912 for detecting the zero position of the card dial 20 and a second sensor 913 for detecting the card dial 20 bin position are arranged on the heat preservation cover 91. Optionally, the first sensor 912 is used to detect the flange on the card dial 20 to position the card dial 20. Similarly, the second sensor 913 is used to detect the flange on the card dial 20 to count.

[0093] In one embodiment, in order to ensure the temperature rising and falling effect of the incubation tray 10, the bottom of the incubation tray 10 is provided with a heating film. The temperature rising and falling mechanism 50 transmits heat to the incubation tray 10 through the heating film, which can ensure the uniformity of the temperature of each part of the incubation tray 10.

[0094] Please refer to Figure 14 、 Figures 14 to 17 In one embodiment, the card feeding device 40 comprises a bracket 41, a first sensor 421, a second driving mechanism 43, a third driving mechanism 44, and a controller. The bracket 41 is provided with a first movement channel 411 and a second movement channel 412, and the first movement channel 411 and the second movement channel 412 are in communication. The first sensor 421 is arranged at the front end of the first movement channel 411 and is used to sense whether the reagent card 80 is inserted into the first movement channel 411. The second driving mechanism 43 is arranged on the bracket 41, and after the reagent card 80 enters the inside of the first movement channel 411, the second driving mechanism 43 drives the reagent card 80 to run to the tail end of the first movement channel 411 and enters the second movement channel 412. The third driving mechanism 44 is arranged on the bracket 41, and the third driving mechanism 44 comprises a first pushing piece 441 which extends into the second movement channel 412 and is used to abut against the front end face of the reagent card 80. The first pushing piece 441 can move along the second movement channel 412 so as to push the reagent card 80 in the second movement channel 412 outwards to the incubation area. The controller is electrically connected with the first sensor 421, the second driving mechanism 43, and the third driving mechanism 44 respectively.

[0095] When the card feeding operation is performed, the reagent card 80 is inserted into the first movement channel 411, and the first sensor 421 can sense that the reagent card 80 is inserted into the first movement channel 411. The controller controls the second driving mechanism 43 to act, and the second driving mechanism 43 drives the reagent card 80 to run to the tail end of the first movement channel 411 and enters the second movement channel 412. In addition, the controller also controls the third driving mechanism 44 to act, and the first pushing piece 441 of the third driving mechanism 44 moves along the second movement channel 412 so as to push the reagent card 80 in the second movement channel 412 outwards to the incubation area. In this way, compared with the traditional way, the reagent card 80 can be accurately and efficiently pushed to the incubation area, and the degree of automation is high. In addition, there is no need to intrude into the incubation area, and the sealing of the incubation area will not be affected, so as to ensure the temperature stability of the incubation area.

[0096] It should be noted that the front end in the present embodiment refers to the end close to the operator, and the tail end refers to the end away from the operator. For example, the front end of the reagent card 80 refers to the end which enters the first movement channel 411 later, and the tail end of the reagent card 80 refers to the end which enters the first movement channel 411 earlier.

[0097] Optionally, the first movement channel 411 and the second movement channel 412 each comprises, but is not limited to, a through hole, a through slot, a guide slot and the like arranged on the support 41.

[0098] Optionally, in order to enable the first push member 441 to extend into the interior of the second movement channel 412, any wall part of the second movement channel 412 is provided with a notch 4121 extending along the extension direction of the second movement channel 412.

[0099] Optionally, the specific form of the support 41 is not limited here and can be flexibly adjusted and arranged according to actual needs. It can be assembled by multiple parts as shown in Figures 14 to 17 or can be designed as an integrated structure by means of welding.

[0100] Referring to Figures 14 to 17 In one embodiment, the card feeding device 40 further comprises a second sensor 422 and a camera 45. The second sensor 422 is arranged at the tail end or the middle part of the first movement channel 411 and is used for sensing the reagent card 80. The camera 45 is arranged on the support 41 and is used for acquiring the bar code information of the reagent card 80. The second sensor 422 and the camera 45 are electrically connected with the controller. In this way, when the tail end surface of the reagent card 80 moves through the second sensor 422, the second sensor 422 can sense the position of the reagent card 80, and the controller calculates the distance that the second driving mechanism 43 needs to push the reagent card 80 forward. Specifically, when the second driving mechanism 43 is provided with a second motor 431, the number of working turns of the second motor 431 is calculated so that the reagent card 80 moves to the shooting position, the camera 45 is opened to identify the bar code information on the reagent card 80, and thus the bar code information of the reagent card 80 is acquired. After the information of the reagent card 80 is successfully identified, the second motor 431 continues to work until the reagent card 80 completely enters the second movement channel 412 and then stops working. When the second sensor 422 detects that the reagent card 80 is not in the first movement channel 411, the third driving mechanism 44 is started after a delay of 0.5 s, so as to transport the reagent card 80 to the incubation area.

[0101] Referring to Figures 14 to 17In one embodiment, the card feeding device 40 further comprises a third sensor 423 and a fourth sensor 424. The third sensor 423 and the fourth sensor 424 are respectively arranged at opposite ends of the second movement channel 412, and are both used for sensing the first pusher 441. The third sensor 423 and the fourth sensor 424 are both electrically connected to the controller. In this way, according to the sensing signals of the third sensor 423 and the fourth sensor 424 on the first pusher 441, the controller can control the first pusher 441 to move back and forth in the region between the third sensor 423 and the fourth sensor 424, so as to ensure the initial position and the end position of the first pusher 441 to be relatively accurate, and ensure the position accuracy of the reagent card 80 when pushed into the incubation region.

[0102] As some optional solutions, the third sensor 423 and the fourth sensor 424 can also be omitted, and the controller can be internally programmed to accurately control the first pusher 441 to move back and forth between the initial position and the end position.

[0103] Optionally, the first sensor 421, the second sensor 422, the third sensor 423 and the fourth sensor 424 each comprise, but are not limited to, a proximity switch, a magnetic sensor, a laser sensor, an ultrasonic sensor, etc.

[0104] Please refer to Figures 14 to 17 In one embodiment, the second driving mechanism 43 comprises a second motor 431, a first driving wheel 432 and at least one first driven wheel 433. The second motor 431 is connected to the first driving wheel 432, which is located at one side of the first movement channel 411 and used for abutting against one side of the reagent card 80. The first driven wheel 433 is located at the other side of the first movement channel 411 and used for abutting against the other side of the reagent card 80. In this way, when the second motor 431 rotates, the first driving wheel 432 is driven to rotate, and since the first driving wheel 432 clamps one side of the reagent card 80 by interference pressure and the first driven wheel 433 clamps the other side of the reagent card 80 by interference pressure, the reagent card 80 can be driven to move forward until the reagent card 80 moves to the tail end of the first movement channel 411 and the reagent card 80 is separated from the first driven wheel 433, at which time the reagent card 80 completely enters the second movement channel 412.

[0105] Optionally, the first driven wheel 433 is a columnar body whose axial cross section comprises, but is not limited to, a circle, an ellipse, a polygon, etc. The specific shape can be flexibly adjusted and set according to actual needs, which is not limited here.

[0106] Please refer to Figures 14 to 17In one embodiment, the bracket 41 is provided with a second elastic member 413, and the first driven wheel 433 is rotatably connected to the second elastic member 413. Optionally, the second elastic member 413 is connected to the wall of the first movement channel 411. In this way, after the reagent card 80 is inserted into the interior of the first movement channel 411, the elastic force provided by the second elastic member 413 causes the first driven wheel 433 to tightly abut against the side of the reagent card 80 located in the first movement channel 411.

[0107] Specifically, the second elastic member 413 includes, but is not limited to, an elastic arm 231, a spring, an elastic block, an elastic column, etc.

[0108] Please refer to Figures 14 to 17 In one embodiment, the first driving wheel 432 and / or the first driven wheel 433 is an elastic wheel. In this way, the first driving wheel 432 and the first driven wheel 433 can be guaranteed to precisely abut against the two opposite sides of the reagent card 80, respectively, and during the rotation of the first driving wheel 432, the reagent card 80 can be stably moved forward to the tail end of the first movement channel 411.

[0109] Specifically, the elastic wheel can be, for example, a rubber wheel, or a wheel with an elastic material layer on the wheel surface.

[0110] Please refer to Figures 14 to 17 In one embodiment, the number of the first driven wheels 433 is at least two. In this way, the first driving wheel 432 and the first driven wheel 433 closest to the front can guarantee the forward and backward movement of the reagent card 80, and the other first driven wheels 433 can keep the movement direction of the reagent card 80 in the channel, so as to smoothly enter the lower channel.

[0111] Please refer to Figures 14 to 17 In one specific embodiment, the number of the first driven wheels 433 is two. Further, the center of the first driving wheel 432, the centers of the two first driven wheels 433 are arranged at the three vertices of a right triangle, or at the three vertices of an isosceles triangle, respectively.

[0112] Please refer to Figures 14 to 17 In one specific embodiment, the number of the first driven wheels 433 is two, and the two first driven wheels 433 are rotatably connected to the same elastic arm 231, for example, to press one side of the reagent card 80 by the elastic force provided by the elastic arm 231, so as to guarantee the tight abutment between the first driving wheel 432 and the reagent card 80, that is, the elastic arm 231 can use a spring and / or an elastic sheet to provide uninterrupted pressing force to the side of the reagent card 80, so that the first driving wheel 432 rotates to correspondingly drive the reagent card 80 to move forward and backward to the required position.

[0113] In one embodiment, the top surface 11 of the first movement channel 411 is provided with a second avoiding part, and the top surface 11 of the reagent card 80 is left with a gap; and / or, the top surface 11 of the second movement channel 412 is provided with a third avoiding part, and the top surface 11 of the reagent card 80 is left with a gap. In this way, after the reagent card 80 is added with samples, the second avoiding part provided on the top surface 11 of the first movement channel 411 can prevent the reagent card 80 from causing cross contamination due to residues on the surface of the reagent card 80. Similarly, after the reagent card 80 is added with samples, the third avoiding part provided on the top surface 11 of the second movement channel 412 can prevent the reagent card 80 from causing cross contamination due to residues on the surface of the reagent card 80.

[0114] In one embodiment, the third driving mechanism 44 comprises a moving mechanism, which comprises a third motor 442, a second driving wheel 443, a second driven wheel 444, and a first transmission element 445. The third motor 442 is connected to the bracket 41, the third motor 442 is connected to the second driving wheel 443, the second driving wheel 443 is connected to the second driven wheel 444 through the first transmission element 445, and the first pushing member 441 is connected to the first transmission element 445.

[0115] In one embodiment, the bracket 41 is further provided with a guide rail 414 and a sliding seat 415 slidingly arranged on the guide rail 414, the guide rail 414 is arranged in the same direction as the extension direction of the second movement channel 412, the sliding seat 415 is connected to the first transmission element 445, and the first pushing member 441 is connected to the sliding seat 415.

[0116] In one embodiment, the first pushing member 441 comprises a first pushing part 4411 and a second pushing part 4412. The first pushing part 4411 is connected to the sliding seat 415, and the second pushing part 4412 is connected to the first pushing part 4411 at one end and is used to abut against the front end surface of the reagent card 80 at the other end.

[0117] Specifically, the second pushing part 4412 is perpendicular to the first pushing part 4411. Alternatively, the first pushing part 4411 and the second pushing part 4412 combine to form an L-shaped rod.

[0118] In one embodiment, the first movement channel 411 is located above the second movement channel 412, and when the reagent card 80 moves to the tail end of the first movement channel 411, the reagent card 80 falls into the inside of the front end of the second movement channel 412. In this way, the tail end of the first movement channel 411 and the front end of the second movement channel 412 overlap with each other, so that the total length of the entire transmission channel is relatively short, which is conducive to reducing the size of the card feeding device 40.

[0119] Please refer to Figure 1In one embodiment, a buffer pad 4122 is arranged on the bottom wall of the second movement channel 412. The buffer pad 4122 includes, but is not limited to, buffer cotton. The buffer pad 4122 can buffer the reagent card 80 dropped from the first movement channel 411 into the second movement channel 412, so as to prevent the reagent card 80 from being damaged and to improve the stability.

[0120] In another embodiment, the first movement channel 411 and the second movement channel 412 are arranged at the same height position of the support 41 in sequence, and the third driving mechanism 44 further includes a lifting mechanism. The lifting mechanism is connected with the lifting member and is used to drive the lifting member to extend into or move out of the second movement channel 412. In this way, the first movement channel 411 and the second movement channel 412 can be combined into one channel. After the second driving mechanism 43 completely pushes the reagent card 80 into the second movement channel 412, the lifting mechanism drives the first pushing member 441 to perform a lifting action, so that the first pushing member 441 extends into the second movement channel 412. Then, the third driving mechanism 44 drives the first pushing member 441 to perform a card feeding action, and the first pushing member 441 drives the reagent card 80 to enter the incubation area. After the reagent card 80 enters the incubation area, the third driving mechanism 44 drives the first pushing member 441 to move reversely and reset, and the lifting mechanism drives the first pushing member 441 to perform a lifting action, so that the first pushing member 441 is reset and moves out of the second movement channel 412, to prepare for the card feeding operation of the next reagent card 80.

[0121] Please refer to Figure 1 In one specific embodiment, the card feeding method of the card feeding device 40 includes the following steps.

[0122] In step S100, when the card feeding operation is performed, the reagent card 80 is inserted into the first movement channel 411. The first sensor 421 can sense that the reagent card 80 is inserted into the first movement channel 411. The controller controls the second driving mechanism 43 to act accordingly, and the second driving mechanism 43 drives the reagent card 80 to run forward.

[0123] In step S200, when the tail end surface of the reagent card 80 moves past the second sensor 422, the second sensor 422 can sense the position of the reagent card 80. The second driving mechanism 43 needs to drive the reagent card 80 to move forward by a distance calculated by software, so that the reagent card 80 stops at the photographing position. The camera 45 is opened to identify the barcode information on the reagent card 80, so as to obtain the barcode information of the reagent card 80.

[0124] In step S300, after the camera 45 successfully identifies the information of the reagent card 80, the second driving mechanism 43 continues to drive the reagent card 80 until the reagent card 80 completely enters the second movement channel 412 and stops working.

[0125] Step S400, after the reagent card 80 falls into the second movement channel 412, the third driving mechanism 44 is started for example for 0.5 seconds, so as to transport the reagent card 80 to the incubation area.

[0126] Please refer to Figures 11 to 13 In an embodiment, the temperature raising and lowering mechanism 50 comprises a semiconductor refrigeration device. The semiconductor refrigeration device is connected to the bottom surface of the incubation disc 10, and is used to transfer heat to the middle part of the bottom surface, so that the middle part of the bottom surface is heated earlier than other areas of the bottom surface; or is used to transfer heat to the circumferential edge part of the bottom surface, so that the circumferential edge part of the bottom surface is heated earlier than other areas of the bottom surface. In this way, in use, the semiconductor refrigeration device transfers heat / cold energy to the middle part of the bottom surface, and the heat / cold energy at the middle part of the bottom surface is conducted to the surrounding, so as to ensure the uniformity of the incubation area of the incubation disc 10 in the circumferential direction, and thus the detection accuracy and efficiency of the reagent card 80; or the semiconductor refrigeration device transfers heat / cold energy to the circumferential edge part of the bottom surface, and the heat / cold energy at the circumferential edge part of the bottom surface is conducted to the center, so as to ensure the uniformity of the incubation area of the incubation disc 10 in the circumferential direction, and thus the detection accuracy and efficiency of the reagent card 80.

[0127] Please refer to Figure 1 、 Figures 11 to 13 In an embodiment, the medical detection device further comprises a first heat conduction device 93 arranged between the incubation disc 10 and the semiconductor refrigeration device. The first heat conduction device 93 is connected to the semiconductor refrigeration device. The first heat conduction device 93 is also connected to the middle part of the bottom surface. In this way, the semiconductor refrigeration device transfers heat / cold energy to the first heat conduction device 93, the first heat conduction device 93 transfers the heat / cold energy to the middle part of the bottom surface, and the middle part of the bottom surface conducts the heat / cold energy to the surrounding, so as to ensure the uniformity of the incubation area of the incubation disc 10 in the circumferential direction, which is conducive to the uniform heating of the plurality of reagent cards 80 arranged circumferentially on the incubation disc 10. In addition, due to the arrangement of the first heat conduction device 93, the energy is transferred to the middle part of the bottom surface of the incubation disc 10 by the first heat conduction device 93, so that the placement position of the semiconductor refrigeration device is more flexible, and can be adjusted at will according to actual needs, so as to avoid some parts (such as the card ejection assembly for ejecting the reagent card 80 outward) in the area below the middle part of the bottom surface of the incubation disc 10, and does not interfere with the parts in the area below the middle part of the bottom surface.

[0128] In another embodiment, the medical detection device further comprises a first heat conducting member 93 arranged between the incubation tray 10 and the semiconductor refrigerating member. The first heat conducting member 93 is connected with the semiconductor refrigerating member. The first heat conducting member 93 comprises a ring-shaped connecting portion arranged in correspondence with the circumferential edge portion of the bottom surface, and the ring-shaped connecting portion is connected with the circumferential edge portion of the bottom surface. In this way, the semiconductor refrigerating member transmits the heat / cold energy to the first heat conducting member 93, and the first heat conducting member 93 transmits the heat / cold energy to the circumferential edge portion of the bottom surface through the ring-shaped connecting portion, so that the heat / cold energy can be conducted to the middle portion of the bottom surface from the circumferential edge portion of the bottom surface, thereby ensuring the uniformity of the incubation area of the incubation tray 10 around the circumferential direction. Due to the arrangement of the first heat conducting member 93, the energy is transmitted to the circumferential edge portion of the bottom surface of the incubation tray 10 by the first heat conducting member 93, so that the placement position of the semiconductor refrigerating member is more flexible, which can be adjusted at will according to actual needs, and the semiconductor refrigerating member does not need to be arranged in a shape corresponding to the circumferential edge portion of the bottom surface.

[0129] As some optional solutions, the first heat conducting member 93 can be omitted, and the semiconductor refrigerating member is directly connected with the middle portion of the bottom surface or directly connected with the circumferential edge portion of the bottom surface.

[0130] Please refer to Figure 1 , Figures 11 to 13 In one embodiment, the first heat conducting member 93 comprises a fitting portion 931 connected with the middle portion of the bottom surface and a heat conducting portion 932 connected with the fitting portion 931. The heat conducting portion 932 is spaced apart from the bottom surface or connected with the bottom surface through a low heat conducting material, and the heat conducting portion 932 is connected with the semiconductor refrigerating member. The semiconductor refrigerating member is located at the peripheral portion of the bottom surface. In this way, the semiconductor refrigerating member specifically transmits the heat / cold energy to the heat conducting portion 932, transmits the heat / cold energy to the fitting portion 931 through the heat conducting portion 932, and transmits the heat / cold energy to the middle portion of the bottom surface connected with the fitting portion 931. In addition, since the semiconductor refrigerating member is located at the peripheral portion of the bottom surface, some components in the area below the middle portion of the bottom surface of the incubation tray 10 can be avoided, i.e., interference with the components in the area below the middle portion of the bottom surface. In addition, since the heat conducting portion 932 is spaced apart from the bottom surface or connected with the bottom surface through a low heat conducting material, the air layer or low heat conducting material can slow down the speed of the heat conducting portion 932 conducting energy to the incubation tray 10 above it, so that the heat / cold energy of the heat conducting portion 932 is mainly transmitted to the fitting portion 931.

[0131] It should be noted that the low heat conducting material is a material with low heat conductivity, and the selection range thereof includes thermal insulation materials or refractory materials, such as but not limited to at least one of aluminum silicate ceramic, chromium aluminum silicate ceramic, alumina ceramic, aerogel material, polyurethane foaming material, etc.

[0132] In one embodiment, the first heat-conducting element 93 includes, but is not limited to, various high-efficiency heat-conducting materials such as copper, copper-aluminum alloy, and graphene film.

[0133] Please see Figure 1 , Figures 11 to 13 In one embodiment, a third recess 16 adapted to the first heat-conducting element 93 is formed on the bottom surface, and the first heat-conducting element 93 is disposed within the third recess 16. Thus, the first heat-conducting element 93 is disposed within the third recess 16 and will not protrude beyond it, thereby ensuring a flat bottom surface of the incubation tray 10. This simplifies the fabrication of the insulation layer on the bottom surface of the incubation tray 10 and provides good insulation performance.

[0134] Please see Figure 1 , Figure 1 In one embodiment, the bottom wall of the third recess 16 is stepped and includes a first wall surface 161 and a second wall surface 162 connected to the first wall surface 161. The fitting portion 931 is fitted to the first wall surface 161, and the heat-conducting portion 932 is spaced from the second wall surface 162. Thus, the first heat-conducting member 93 is, for example, a flat plate, and when the fitting portion 931 of the first heat-conducting member 93 is fitted to the first wall surface 161, the heat-conducting portion 932 naturally forms a gap with the second wall surface 162.

[0135] Of course, as some alternative solutions, it is not limited to setting the bottom wall of the third recess 16 in a stepped shape, but for example, setting the first heat-conducting member 93 in a stepped shape and setting the bottom wall of the third recess 16 in a flat shape, so that when the fitting part 931 and the bottom wall of the third recess 16 are fitted together, the heat-conducting part 932 and the bottom wall of the third recess 16 are spaced apart.

[0136] Please see Figure 7 In one embodiment, the medical testing device further includes a heat insulation plate 94 and a heat dissipation assembly 95. The heat insulation plate 94 is in contact with the bottom surface of the incubation tray 10, and the heat insulation plate 94 has a first window 941 corresponding to the position of the thermoelectric cooler. The heat dissipation assembly 95 passes through the first window 941 and is connected to the thermoelectric cooler. In this way, the heat insulation plate 94 insulates the bottom surface of the incubation tray 10, preventing energy loss from the incubation tray 10 to the outside, thus providing good temperature control for the reagent card 80 located above its top surface 11. In addition, the thermoelectric cooler is also connected to the heat dissipation assembly 95, which dissipates the (cold / hot) energy on the side of the thermoelectric cooler facing away from the incubation tray 10 in a timely manner, thereby ensuring the working performance of the thermoelectric cooler.

The heat dissipation plate 951 is connected to the heat dissipation fins 953 through the second heat conducting member 952, and the heat dissipation fan 954 is connected to the heat dissipation fins 953. In this way, the (cold / heat) energy of the heat dissipation plate 951 is transmitted to the heat dissipation fins 953 through the second heat conducting member 952, and the heat dissipation fan 954 dissipates the (cold / heat) energy outward when it works, so that the heat dissipation effect is good.

[0138] Optionally, the second heat conducting member 952 comprises, but is not limited to, a metal rod such as a heat-conducting copper rod, a heat-conducting aluminum rod, etc., for example, one, two, three or more than four. One end of the second heat conducting member 952 is arranged through the heat dissipation plate 951, and the other end of the second heat conducting member 952 is connected to the heat dissipation fins 953. The second heat conducting member 952 not only can transmit the energy of the heat dissipation plate 951 to the heat dissipation fins 953, but also can flexibly adjust the shape of the second heat conducting member 952 according to actual needs, so that the heat dissipation fins 953 and the heat dissipation fan 954 can be flexibly arranged inside the case. Optionally, the shape of the second heat conducting member 952 comprises, but is not limited to, various regular shapes or irregular shapes such as straight line type, L shape, S shape, etc. In this embodiment, the second heat conducting member 952 is specifically arranged in L shape.

[0139] Please refer to Figure 1 In one embodiment, the medical detection device further comprises a heat preservation ring 17 arranged around the incubation disc 10. In this way, the heat preservation ring 17 plays a heat preservation role on the incubation disc 10 in the circumferential direction of the incubation disc 10, preventing the energy on the incubation disc 10 from being dissipated to the outside, so that the incubation disc 10 has a good temperature control effect on the reagent cards 80 located above the top surface 11 thereof.

[0140] It should be noted that the incubation disc 10 comprises, but is not limited to, a disc body with regular shapes or irregular shapes such as a circular disc, an elliptical disc, a polygonal disc, etc. The polygonal disc comprises, but is not limited to, a triangular disc, a quadrilateral disc, a pentagonal disc, etc. In this embodiment, the incubation disc 10 is specifically selected as a circular disc, and the reagent cards 80 are multiple and arranged in sequence and at intervals around the circumferential direction of the incubation disc 10, so that the uniformity of the incubation area of the incubation disc 10 around the circumferential direction thereof can be ensured, and the detection accuracy and efficiency of the reagent cards 80 can be ensured.

[0141] Please refer to Figures 8 to 10In one embodiment, the medical detection device further comprises a fixing frame 18 arranged on the bottom surface of the incubation tray 10. The fixing frame 18 crosses the third recess 16 and plays a certain fixing role for the first heat-conducting member 93 located in the third recess 16. In addition, the semiconductor refrigeration member is arranged in the interior of the fixing frame 18, that is, the fixing frame 18 also plays a fixing role for the semiconductor refrigeration member. In addition, the heat-dissipating plate 951 is connected with the fixing frame 18, so that the stable connection between the heat-dissipating assembly 95 and the incubation tray 10 is ensured, and the reliability of heat dissipation is ensured.

[0142] Referring to Figures 11 to 13 , Figure 1 In one embodiment, the outer periphery of the top surface 11 is formed with a circumferentially arranged flow guide groove 12, and the incubation tray 10 is further provided with a flow guide hole 13 in communication with the flow guide groove 12. The medical detection device further comprises an evaporation tray 98. The evaporation tray 98 is located below the incubation tray 10 and is used to receive the condensed water falling from the flow guide hole 13. The temperature raising and lowering mechanism 50 is further used to heat treat the evaporation tray 98, so that the condensed water in the interior of the evaporation tray 98 is evaporated. In this way, during operation, the card driving turntable 20 drives the reagent card 80 to rotate, and at the same time, the incubation tray 10 lowers the temperature of the reagent card 80 by contacting the reagent card 80 to achieve the incubation operation in a preset range. When the top surface 11 of the incubation tray 10 encounters hot air to generate condensed water, the condensed water generated on the surface of the incubation tray 10 is thrown into the flow guide groove 12 by the centrifugal force of the rotating reagent card 80, and the condensed water collected in the flow guide groove 12 falls downward to the evaporation tray 98 through the flow guide hole 13. The temperature raising and lowering mechanism 50 is used to heat treat the evaporation tray 98, so that the condensed water in the interior of the evaporation tray 98 is evaporated in time, without worrying about the water in the evaporation tray 98 overflowing, without the need for manual water pouring, and being able to process the condensed water in time, so as to ensure that the product performance is not affected by the condensed water.

[0143] Referring to Figures 8 to 10 In one embodiment, the semiconductor refrigeration member is further connected with the evaporation tray 98 through the heat-dissipating plate 951. In this way, the heat-dissipating plate 951 can transfer heat to the evaporation tray 98, and the evaporation tray 98 uses the heat to heat the condensed water in the interior thereof to evaporate the condensed water.

[0144] In another embodiment, the temperature raising and lowering mechanism 50 further comprises a heater (not shown in the figure). The heater is used to heat treat the evaporation tray 98, so that the condensed water in the interior of the evaporation tray 98 is evaporated after being heated. The heater includes but is not limited to various heating structures such as a heating wire, a heating rod, etc.

[0145] Referring to Figure 1In one embodiment, the reagent card 80 incubation mechanism further comprises a machine box (not shown in the figure). The incubation tray 10, the card dialing turntable 20, the evaporation tray 98, the temperature raising and lowering mechanism 50, and the heat dissipation assembly 95 are all arranged inside the machine box. The machine box is provided with an air inlet and an air outlet; the evaporation tray 98 and the heat dissipation fan 954 are arranged in sequence on the air duct formed by the air inlet and the air outlet. The air inlet is arranged opposite to the evaporation tray 98, and the air outlet is arranged opposite to the heat dissipation fan 954. In this way, when the heat dissipation fan 954 is working, power is formed, so that the air outside the machine box enters through the air inlet, and then flows through the evaporation tray 98 and the heat dissipation assembly 95 and is discharged to the outside of the machine box through the air outlet, that is, the hot steam generated by the evaporation tray 98 can be smoothly discharged to the outside of the machine box, so that the detection instruments inside the machine box can be prevented from being adversely affected by the hot steam.

[0146] Please refer to Figures 11 to 13 In one embodiment, the reagent card 80 incubation mechanism further comprises a flow guide 97. One end of the flow guide 97 is connected to the hole wall of the flow guide hole 13, and the other end of the flow guide 97 extends into the evaporation tray 98. In this way, under the flow guiding effect of the flow guide 97, the condensed water in the flow guide groove 12 is smoothly discharged to the inside of the evaporation tray 98 through the flow guide hole 13.

[0147] Optionally, the flow guide 97 includes but is not limited to a flow guide pipe, a drainage rod, etc. In this embodiment, the flow guide 97 is arranged as a flow guide pipe. Specifically, the cross section of the flow guide pipe presents a decreasing trend from the flow guide hole 13 to the evaporation tray 98, so that the condensed water can be gathered into the evaporation tray 98.

[0148] In one embodiment, the reagent card 80 incubation mechanism further comprises a blowing member (not shown in the figure). The air outlet side of the blowing member is opposite to the evaporation tray 98. In this way, the blowing member blows the evaporation tray 98, which can accelerate the evaporation of the condensed water in the evaporation tray 98.

[0149] Optionally, the blowing member includes but is not limited to a fan or other devices capable of sending gas into the evaporation tray 98 to accelerate the evaporation of the condensed water in the evaporation tray 98.

[0150] In one embodiment, the heat preservation plate 94 is further provided with a second window 942 adapted to the flow guide 97. The flow guide 97 is arranged in the second window 942.

[0151] In one embodiment, the calculation scheme of the present embodiment is as follows:

[0152] By monitoring the ambient temperature and the incubation tray 10 temperature, by the control formula t=Ttray-Tring, by comparing the t value is positive or negative, the MCU controls the current direction of the Peltier, changes the cold end and the hot end of the Peltier, and realizes the incubation tray 10 cooling or heating control.

[0153] The dynamically adjusted heating output is u(k),

[0154] u(k) = Kp * e(k) + Ka * Ki *∑e(j) + Kb * Kd * [e(kn) - e(k0)].

[0155] When |e(j)|≤A, ka=1; when |e(j)|>A, ka=0, A is an integral action threshold.

[0156] When |e(kn)-e(k0)|≤B, kb=1; when |e(kn)-e(k0)|>B, kb=0, wherein B is a differential action threshold, Kp, Ki, and Kd are proportional, integral, and differential action coefficients respectively, e(k) is an input deviation,∑e(j) is a sum of input deviations, and e(kn) is a measured value.

[0157] In one embodiment, the card ejection mechanism 70 includes a pushing mechanism 71 and a second pushing piece 72 connected to the pushing mechanism 71. The incubation tray 10 is provided with a movable port 14 arranged in a radial direction, and the second pushing piece 72 is movably arranged in the movable port 14. In this way, when the pushing mechanism 71 drives the second pushing piece 72 to move along the movable port 14, the second pushing piece 72 can push the reagent card 80 on the incubation tray 10 in the radial direction of the incubation tray 10 to the outside of the accommodation groove 21, thereby realizing the card ejection operation. At the same time of the card ejection operation, the reagent card 80 plays a role of liquid scraping, that is, the reagent card 80 scrapes the condensed water on the surface of the incubation tray 10 into the flow guide groove 12.

[0158] Please refer to Figure 10 and Figure 1 In addition, in order to avoid the second pushing piece 72, the fitting part 931 is provided with a second avoiding port 9311 for avoiding the second pushing piece 72, so that the second pushing piece 72 extends into the movable port 14 through the second avoiding port 9311.

The second transmission element 715 is connected with the second pushing member 72, and is configured to drive the second pushing member 72 to move back and forth. Optionally, the second pushing member 72 is slidingly arranged on the support frame 711, so as to ensure the stability of operation.

[0161] Referring to Figure 1 and Figure 10 In one embodiment, the edge of the incubation tray 10 is provided with a baffle 15 arranged around the circumference thereof, and the baffle 15 protrudes above the top surface 11. In this way, the baffle 15 plays a role of blocking liquid, and can prevent the condensed liquid on the surface of the incubation tray 10 from being thrown out of the incubation tray 10 under the action of centrifugal force, so that the condensed liquid enters the flow guide groove 12.

[0162] Referring to Figure 11 , Figures 18 to 20 and Figures 18 to 20 The baffle 15 is also provided with a discharge port 151 arranged opposite to the movable port 14. When the pushing mechanism 71 drives the second pushing member 72 to move the reagent card 80 along the radial direction of the incubation tray 10, the reagent card 80 is discharged outward through the discharge port 151.

Each optical path assembly 63 comprises a light source excitation module 631, a first filter 632, a dichroic mirror 633, and a second filter 634. The light source excitation module 631 is configured to provide an excitation light beam. The first filter 632 is arranged on the light exit side of the light source excitation module 631, and the dichroic mirror 633 is arranged at an angle with respect to the first filter 632 and the second filter 634. The excitation light beam passes through the first filter 632 and the dichroic mirror 633, and is used to be incident on the reagent card. The fluorescence generated by the reagent card is transmitted to the dichroic mirror 633, and then passes through the second filter 634 to be detected and processed by the detection circuit board 62.

[0164] The fluorescence detection device 60 described above, for each optical path assembly 63, when the light source excitation module 631 is turned on, the excitation light beam passes through the first filter 632 for light filtering, and after being reflected by the dichroic mirror 633, it enters the reagent card 80, excites the fluorescent microspheres, and thus forms fluorescent light of a specific wavelength. The fluorescent light passes through the dichroic mirror 633 and the second filter 634 and is detected by the detection circuit board 62. The structures of the various optical path assemblies 63 are the same, and the only difference is the wavelength of the excitation light beam, so that at least two different types of fluorescent microspheres combined together can be detected, with high detection sensitivity and a large linear range.

[0165] Referring to Figures 18 to 20 Specifically, the detection circuit board 62 is provided with at least two fluorescence collection parts 621 corresponding to the at least two optical path assemblies 63. In this way, when the cylindrical lens 636 can collect the fluorescent light into the fluorescence collection part 621, the fluorescence collection part 621 converts the fluorescent light into an electrical signal, and the detection circuit board 62 analyzes and processes the electrical signal.

[0166] Optionally, the fluorescence collection part 621 includes but is not limited to a photodiode.

[0167] In addition, a 24-bit AD (analog-to-digital converter) is used on the detection circuit board 62 to digitize and sample the analog electrical signal of the photodiode, forming data that can be processed by software.

[0168] Optionally, the light source excitation module 631 is an LED light source for emitting excitation light of a specific wavelength.

The collimating lens 635 is arranged between the light source excitation module 631 and the first filter 632. The excitation light beam of the light source excitation module 631 passes through the collimating lens 635 for collimation processing and then enters the first filter 632.

[0171] Referring to Figures 18 to 20 Optionally, the light source excitation module 631, the collimating lens 635, and the first filter 632 are coaxially arranged.

[0172] Referring to Figures 18 to 20In one embodiment, the fluorescence detection device 60 further comprises a first light shield 64 disposed inside and connected to the shell 611. The first light shield 64 is disposed outside the light source excitation module 631 and the collimating lens 635, and a first light transmission hole 641 is disposed on the wall of the first light shield 64 opposite to the collimating lens 635. In this way, the first light shield 64 can isolate the excitation light and the ambient stray light from entering the emission light path to a certain extent, thereby reducing the noise of the fluorescence signal collected by the photodiode.

[0173] Referring to Figures 18 to 20 In one embodiment, the light path assembly 63 further comprises a cylindrical lens 636. The cylindrical lens 636 is disposed at an angle with the dichroic mirror 633, and the cylindrical lens 636 is disposed opposite to the position of the detection part of the reagent card 80. The excitation light beam reflected by the dichroic mirror 633 passes through the cylindrical lens 636 and irradiates the detection part of the reagent card 80. In this way, the excitation light beam forms a strip-shaped excitation spot after passing through the cylindrical lens 636, and the strip-shaped excitation spot is incident into the detection part of the reagent card 80. Since the strip-shaped excitation spot can completely cover the fluorescent strip on the reagent card 80, the fluorescence excitation efficiency can be significantly improved.

[0174] Referring to Figures 18 to 20 In one embodiment, the detection circuit board 62 is provided with at least two fluorescence collection parts 621 corresponding to at least two light path assemblies 63. The light path assembly 63 further comprises a condenser lens 637. The condenser lens 637 is disposed between the second filter 634 and the fluorescence collection part 621. The fluorescence filtered by the second filter 634 is incident into the fluorescence collection part 621 after being condensed by the condenser lens 637.

[0175] Referring to Figures 18 to 20 Optionally, the cylindrical lens 636, the second filter 634, and the condenser lens 637 are coaxially arranged.

The second light shield 65 is disposed outside the fluorescence collection part 621 and the condenser lens 637, and a second light transmission hole 651 is disposed on the wall of the second light shield 65 opposite to the condenser lens 637. In this way, the second light shield 65 can isolate the excitation light and the ambient stray light from entering the emission light path to a certain extent, thereby reducing the noise of the fluorescence signal collected by the photodiode.

[0177] Referring to Figures 18 to 20 In one embodiment, the second light shield 65 is provided with a diaphragm 652, and the diaphragm 652 is provided with a light transmission hole 6521 in the middle part. The diaphragm 652 is located between the fluorescence collection part 621 and the condenser lens 637.

[0178] Please see Figures 18 to 20 In one embodiment, the inner wall of the housing 611 is provided with an extinction surface 6111 that is angled to the horizontal plane 66. The extinction surface 6111 and the first filter 632 are located on opposite sides of the dichroic mirror 633. In this way, the extinction surface 6111 can reflect the excitation light from the LED light source that arrives there to other places, instead of entering the emission light path and thus forming the background noise of the fluorescence signal. Optionally, the angle between the extinction surface 6111 and the horizontal plane 66 is less than 45°, which is different from the 45° angle between the dichroic mirror 633 and the horizontal plane 66, resulting in less stray light and achieving a better extinction effect.

[0179] Please see ​ In one embodiment, the housing 611 comprises two separate housings (not shown in the figure). The two separate housings are detachably connected. Thus, when the housing 611 is configured as two detachably connected separate housings, it facilitates the installation and removal of the optical path assembly 63 into the housing 611. Specifically, the two separate housings are connected to each other using fasteners such as screws, pins, and rivets, or by means such as snap-fit ​​connections.

[0180] Optionally, at least two housings 611 are connected in sequence.

[0181] Please see ​ In one embodiment, one of the split shells has a second protrusion at its mating portion, and the other split shell has a fourth recess corresponding to the second protrusion at its splicing portion. The second protrusion is inserted into the fourth recess. In this way, the two split shells are fitted into the fourth recess through the second protrusion, ensuring the stability of the spliced ​​connection between the two.

[0182] In one embodiment, after the outer shell 611 is configured as two separate shells, the matte surface 6111 is correspondingly divided into two parts, which are respectively disposed on the two separate shells.

[0183] In one embodiment, after the outer shell 611 is set as two separate shells, the light-transmitting hole 6521 is correspondingly divided into two parts. For example, one separate shell is provided with a semi-circular hole, and the other separate shell is provided with a semi-circular hole, which are spliced ​​together to form a circular light-transmitting hole 6521.

[0184] In a specific embodiment, the optical path component 63 described above, when in operation, includes a fluorescence excitation process and a fluorescence emission process, wherein:

[0185] The fluorescence excitation process, the LED light source emits excitation light of a specific wavelength, which becomes parallel light through the collimating lens 635, and then the stray light outside the excitation light wavelength range is filtered out by the first filter 632, and then reflected by the dichroic mirror 633 into the columnar lens 636, focused into a strip-shaped light spot on the detection part of the reagent card 80, and the fluorescence microspheres of the detection part of the reagent card 80 are excited to emit fluorescence.

[0186] The fluorescence emission process, the fluorescence generated by the detection part of the reagent card 80 is collected by the columnar lens 636, then passes through the dichroic mirror 633, and then the excitation light and environmental stray light are filtered out by the second filter 634, and finally collected into the photodiode through the condenser lens 637. The photodiode converts the fluorescence into an electrical signal, which is digitized by the 24-bit AD (analog-to-digital converter) on the acquisition circuit to form data that can be processed by software. The use of the 24-bit AD (analog-to-digital converter) can increase the number of bits of the signal data, greatly improving the measurement linear range and detection sensitivity.
