TECHNICAL FIELD

[0001] The utility model relates to medical technology field especially, and it is a kind of microfluidic chemical luminescence analyzer. BACKGROUND

[0002] In the field of microfluidic chemical luminescence analysis, the reagent disc in-out warehouse structure commonly used in the prior art has many shortcomings. First, such structure is usually complex, and additional external space is needed when the reagent disc is out of the warehouse, which not only increases the volume of the equipment, but also may cause waste of laboratory space. Secondly, the traditional equipment is usually equipped with a warehouse door structure, and when the reagent disc is placed on the warehouse door, the warehouse door is often stuck due to improper placement. This not only affects the operation efficiency of the equipment, but also may negatively affect the accuracy of the experimental results. In addition, the existing warehouse door design can usually only be applied to reagent discs of a specific size, limiting the versatility and flexibility of the equipment.

[0003] With the increasing requirements of laboratories for the portability, ease of operation and diversified adaptability of equipment, there is an urgent need in the market for an innovative solution that can overcome the above problems. Therefore, it is necessary to develop a microfluidic chemical luminescence analyzer that optimizes space utilization, simplifies operation process and improves equipment reliability.

[0004] The above information disclosed in the background of the present application is only for understanding the background of the concept of the present application, and does not indicate or imply that it contains prior art information. CONTENT OF THE UTILITY MODEL

[0005] Therefore, it is necessary to provide a microfluidic chemical luminescence analyzer for the above problems.

[0006] A microfluidic chemical luminescence analyzer comprises:

[0007] a housing, the housing is provided with an inlet;

[0008] a warehouse door, the warehouse door is rotatably connected with the housing;

[0009] a bearing assembly for bearing a reagent disc;

[0010] a drive assembly connected with the bearing assembly and used for driving the bearing assembly;

[0011] a connecting rod assembly connected with the warehouse door, the connecting rod assembly can drive the warehouse door to move to a first position and a second position relative to the housing; in the first position, the warehouse door is opened, the inlet is exposed, and the bearing assembly is at least partially located outside the inlet; in the second position, the warehouse door is closed, the inlet is blocked by the warehouse door, and the bearing assembly is located in the housing.

[0012] The microfluidic chemiluminescence analyzer has at least the following beneficial effects: the microfluidic chemiluminescence analyzer has innovative structural design, and remarkable technical effects are achieved. First, the door state can be switched between the first position and the second position by the ingenious connection of the connecting rod assembly and the door. When the door is in the first position, the door is opened, the inlet is exposed, and the user can conveniently operate and replace the reagent disc on the bearing assembly. When the door is in the second position, the door is closed, and the sealing and safety of the equipment are ensured. This design effectively reduces the volume of the equipment shell, so that the equipment is more compact and suitable for use in a laboratory environment with limited space. In addition, the bearing assembly is used to carry the reagent disc and can be flexibly moved between the outside and the inside by the driving of the driving assembly, so as to ensure the stable placement of the chip and the convenience of operation. The flexible movement of the bearing assembly also avoids the problem of occupying external space when the reagent disc is taken out of the traditional equipment.

[0013] In some embodiments, the microfluidic chemiluminescence analyzer further comprises a sliding block slidably arranged in the shell, one end of the sliding block is rotatably connected with the connecting rod assembly, and the other end of the connecting rod assembly is connected with the door. The sliding block can drive the connecting rod assembly to move to the first position and the second position.

[0014] In some embodiments, the microfluidic chemiluminescence analyzer further comprises a guide rod arranged in the shell, the length extension direction of the guide rod is parallel to the orientation of the inlet, and the sliding block is slidably sleeved on the outer circumferential surface of the guide rod. The sliding block is rotatably connected with one end of the connecting rod assembly, and the other end is connected with the door. This structure enables the sliding block to smoothly drive the connecting rod assembly to move to the first position and the second position. In actual operation, the addition of the sliding block makes the opening and closing of the door more smooth, and reduces the instability and errors caused by manual operation. The sliding property of the sliding block provides a better force transmission path, ensuring the stability and accuracy of the door during opening and closing, and avoiding the jamming or wear problems that may be caused by the direct driving of the connecting rod assembly. This design not only improves the durability of the equipment, but also enhances the convenience and safety of user operation, further optimizing the use experience of the equipment in the laboratory environment. In this way, the analyzer can maintain efficient operation while providing longer service life and lower maintenance requirements.

[0015] In some embodiments, the microfluidic chemiluminescence analyzer further comprises an elastic member sleeved on the outer circumferential surface of the guide rod, the elastic member being connected to one side of the sliding block close to the door, the sliding block being capable of extruding the elastic member under external force to move to the first position, and the sliding block being capable of rebounding to the second position under the elastic force of the elastic member. The microfluidic chemiluminescence analyzer adds a guide rod arranged in the shell, which further improves the operation precision and structural stability of the device. The length extension direction of the guide rod is parallel to the orientation of the inlet, and the sliding block is slidably sleeved on the outer circumferential surface of the guide rod. This design ensures smooth sliding of the sliding block along the guide rod, avoiding the situation of deviation or shaking of the sliding block during movement, thereby improving the accuracy and reliability of the movement of the door driven by the connecting rod assembly. The presence of the guide rod provides a clear movement trajectory for the sliding block, making the entire opening and closing process more smooth, reducing the resistance and wear caused by friction or misalignment. This not only improves the durability of the device, but also enhances the smoothness and safety of user operation, ensuring that good performance can still be maintained in frequent use. Through this optimized structural design, the analyzer can provide more stable and efficient operation experience in complex laboratory environments.

[0016] In some embodiments, the bearing assembly is capable of moving to the first position and the second position under the driving of the driving assembly, the bearing assembly part being connected with the sliding block, in the first position, the bearing assembly drives the sliding block to move in the direction of stretching out of the inlet and extrudes the elastic member, and in the second position, the bearing assembly drives the sliding block to move in the direction of retracting into the inlet and the elastic member rebounds. This design enables the bearing assembly to achieve multifunctional operation in different positions. In the first position, the bearing assembly drives the sliding block to move in the direction of stretching out of the inlet while extruding the elastic member. This process not only ensures stable movement of the sliding block, but also provides additional buffering and stability through extrusion of the elastic member, reducing impact and wear that may be caused by sudden movement. When the bearing assembly moves to the second position, the sliding block moves in the direction of retracting into the inlet, and the rebounding action of the elastic member is realized. The rebounding of the elastic member can help the sliding block to smoothly reset.

[0017] In some embodiments, the carrier assembly comprises a carrier plate for carrying the reagent disc and a guide recess connected to the carrier plate, the guide recess being slidably fitted to the guide rod. The design of the carrier assembly includes a carrier plate and a guide recess connected to the carrier plate. The main function of the carrier plate is to carry the reagent disc, which is crucial for sample processing during the experiment and analysis process. The guide recess is provided on the carrier plate, which allows the carrier plate to be slidably fitted to the guide rod. This design provides a stable and controllable movement path through the cooperation of the guide recess and the guide rod, allowing the carrier assembly to maintain accurate positioning and smooth sliding during movement. The presence of the guide recess not only ensures the stability of the carrier assembly, but also reduces errors and mechanical wear caused by improper movement. Through this structural design, the microfluidic chemiluminescence analyzer can achieve high-precision chip positioning and processing during operation, ensuring the accuracy and repeatability of experimental results.

[0018] In some embodiments, the number of link assemblies and sliders is set to two and one-to-one correspondence, two link assemblies are respectively arranged on the left and right sides of the carrier plate, the number of guide recesses is set to two, and two guide recesses are respectively located on the left and right sides of the carrier plate, one guide recess is slidably fitted to one guide rod, and the other guide recess is slidably fitted to the other guide rod. This configuration aims to enhance the stability and symmetry of the system. Specifically, two link assemblies are respectively arranged on the left and right sides of the carrier plate, and this symmetrical design helps to maintain balance during operation and reduces the risk of deviation or tilting. The left and right sides of the carrier plate are respectively provided with one guide recess, and each guide recess is used in cooperation with one guide rod. In this way, one guide recess can be slidably fitted to one guide rod, and the other guide recess cooperates with the other guide rod. This double-guide design not only improves the movement accuracy of the carrier assembly, but also enhances the stability of the overall structure. Through this arrangement, the carrier assembly can maintain a smooth and precise movement path during movement, ensuring accurate positioning of the reagent disc during the experiment. This design not only improves the operation performance of the equipment, but also reduces experimental deviations caused by mechanical errors, thereby improving the reliability and repeatability of experimental results.

[0019] In some embodiments, the carrying plate is provided with an adaptive slot on the side facing the entrance, and the reagent disc is disc-shaped and at least partially extends into the adaptive slot. In these embodiments, the carrying plate is carefully designed to accommodate reagent discs of different diameters. Specifically, the carrying plate is provided with an adaptive slot on the side facing the entrance, and the slot is designed to allow the reagent disc to partially extend into it, thereby achieving stable placement and positioning. The reagent disc is designed to be disc-shaped, which facilitates rotation and fixation in the adaptive slot. The flexible design of the adaptive slot allows disc-shaped reagent discs of different diameters to be adapted, greatly increasing the versatility and applicability of the structure. Through this design, users can use reagent discs of different sizes in the same device without the need to replace the device or make complex adjustments. In order to adapt to reagent discs of different diameters, the entrance and exit positions of the carrying plate can be adjusted according to the size of the reagent disc. Specifically, when using a smaller reagent disc, the entrance structure will move forward accordingly to ensure that the reagent disc can correctly enter the adaptive slot and remain stable. This flexible drive structure design ensures that the device can always operate efficiently and accurately when handling reagent discs of different sizes.

[0020] In some embodiments, the door is provided with two limiting tabs inward along the entrance, and the two limiting tabs are respectively connected to the two sides of the door and used for limiting the reagent disc. In these embodiments, in order to ensure the stability and accurate positioning of the reagent disc in the warehouse, the door is designed with two limiting tabs. The two limiting tabs are inwardly arranged along the entrance and located on the two sides of the door. The main function of the limiting tab is to provide lateral support and positioning for the reagent disc. When the reagent disc is placed in the warehouse, the limiting tab can effectively limit its lateral movement and prevent it from shifting or shaking during operation. This design not only improves the stability of the reagent disc, but also ensures the accuracy and safety during device operation. By connecting the limiting tabs to the two sides of the door, the entire structure effectively limits the reagent disc. This design simplifies the placement process of the reagent disc, allowing users to quickly and accurately place the reagent disc in the warehouse without the need for additional adjustments or fixation. In addition, this limiting design also has flexibility and can adapt to reagent discs of different sizes. The position and height of the limiting tab can be adjusted according to the specific specifications of the reagent disc, thereby meeting various experimental needs.

[0021] In some embodiments, the drive assembly includes a motor and a synchronous belt, one end of the synchronous belt is connected to the output shaft of the motor, and the other end of the synchronous belt is connected to the carrying assembly.

[0022] In some embodiments, the linkage assembly includes a first linkage and a second linkage, one end of the first linkage is rotatably connected with the slider, the other end of the first linkage is rotatably connected with one end of the second linkage, and the other end of the second linkage is connected with the door. The linkage assembly is composed of the first linkage and the second linkage, and through the ingenious connection mode, the smooth movement of the door is ensured. Specifically, one end of the first linkage is rotatably connected with the slider, and this connection allows the first linkage to rotate with the movement of the slider. The other end of the first linkage is rotatably connected with one end of the second linkage, which allows flexible transmission of motion between the two linkages. The other end of the second linkage is connected with the door, which means that when the slider moves, the door can be opened or closed accordingly through the transmission of the linkage assembly. The advantage of this design is that the rotational movement of the door can be controlled through the linear movement of the slider to achieve the opening and closing of the door. The design of this linkage assembly not only makes the operation of the door smoother and more reliable, but also reduces friction and wear, improves the durability of the equipment. In addition, by adjusting the length and connection angle of the linkages, the opening angle and speed of the door can be accurately controlled to meet different operation requirements. In summary, the design of this linkage assembly provides an efficient mechanical transmission solution for the automatic control of the door, improving the performance and user experience of the overall equipment.

In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the present application provides a microfluidic chemiluminescence analyzer 10, which comprises a shell 100, a door 200, a bearing assembly 300, a drive assembly 400 and a connecting rod assembly 500. Wherein, the shell 100 is provided with an inlet 110; the door 200 is rotationally connected with the shell 100; the bearing assembly 300 is used for bearing a reagent disc 900; the drive assembly 400 is connected with the bearing assembly 300 and is used for driving the bearing assembly 300; the connecting rod assembly 500 is connected with the door 200, and the connecting rod assembly 500 can drive the door 200 to move relative to the shell 100 to a first position and a second position. When in the first position, the door 200 is opened, the inlet 110 is exposed, and the bearing assembly 300 is at least partially located outside the inlet 110. As shown in Figure 1 and Figure 2 When in the second position, the door 200 is closed, the inlet 110 is shielded by the door 200, and the bearing assembly 300 is located in the shell 100.

[0032] The microfluidic chemiluminescence analyzer 10 has at least the following beneficial effects: the microfluidic chemiluminescence analyzer 10 has innovative structural design, and remarkable technical effects are achieved. First, the door 200 can be easily switched between the first position and the second position by the ingenious connection of the connecting rod assembly 500 and the door 200. When in the first position, the door 200 is open, the inlet 110 is exposed, and the user can conveniently operate and replace the reagent disc 900 on the bearing assembly 300. When in the second position, the door 200 is closed, ensuring the closure and safety of the equipment. This design effectively reduces the volume of the equipment shell 100, making the equipment more compact and suitable for use in a laboratory environment with limited space. In addition, the bearing assembly 300 is used to carry the reagent disc 900 and can be flexibly moved between the outside and the inside by the driving of the driving assembly 400, ensuring the stable placement of the chip and the convenience of operation. The flexible movement of the bearing assembly 300 also avoids the problem of occupying external space when the reagent disc 900 is taken out of the traditional equipment.

[0033] Specifically, as shown in Figure 4 some embodiments, the microfluidic chemiluminescence analyzer 10 further comprises a sliding block 600 slidably arranged in the shell 100, one end of the sliding block 600 is rotatably connected with the connecting rod assembly 500, and the other end of the connecting rod assembly 500 is connected with the door 200. The sliding block 600 can drive the connecting rod assembly 500 to move to the first position and the second position.

[0034] Specifically, as shown in Figure 2 and Figure 4 some embodiments, the microfluidic chemiluminescence analyzer 10 further comprises a guide rod 700 arranged in the shell 100, the length extension direction of the guide rod 700 is parallel to the orientation of the inlet 110, and the sliding block 600 is slidably sleeved on the outer side surface of the guide rod 700. The sliding block 600 is rotatably connected with one end of the connecting rod assembly 500, and the other end is connected with the door 200. This structure enables the sliding block 600 to smoothly drive the connecting rod assembly 500 to move to the first position and the second position. In actual operation, the addition of the sliding block 600 makes the opening and closing of the door 200 more smooth, reducing the instability and errors caused by manual operation. The sliding property of the sliding block 600 provides a better force transmission path, ensuring the stability and accuracy of the door 200 during opening and closing, and avoiding the jamming or wear problems that may be caused by the direct driving of the connecting rod assembly 500. This design not only improves the durability of the equipment, but also enhances the convenience and safety of user operation, further optimizing the use experience of the equipment in the laboratory environment. In this way, the analyzer can maintain efficient operation while providing longer service life and lower maintenance requirements.

[0035] Specifically, such as Figure 4 As shown, in some embodiments, the microfluidic chemiluminescence analyzer 10 further includes an elastic element 800 sleeved on the outer peripheral surface of the guide rod 700. The elastic element 800 is connected to the side of the slider 600 near the chamber door 200. The slider 600 can be squeezed by an external force to move to the first position, and the slider 600 can also rebound and return to the second position under the elastic force of the elastic element 800. The microfluidic chemiluminescence analyzer 10 adds a guide rod 700 disposed within the housing 100. This design further improves the operating accuracy and structural stability of the device. The length extension direction of the guide rod 700 is parallel to the orientation of the inlet 110, and the slider 600 is slidably sleeved on the outer peripheral surface of the guide rod 700. This design ensures the smooth sliding of the slider 600 along the guide rod 700, avoiding deviation or wobbling of the slider 600 during movement, thereby improving the accuracy and reliability of the linkage assembly 500 driving the movement of the chamber door 200. The presence of the guide rod 700 provides a clear movement trajectory for the slider 600, making the entire opening and closing process smoother and reducing resistance and wear caused by friction or misalignment. This not only improves the durability of the device but also enhances the smoothness and safety of user operation, ensuring good performance even under frequent use. Through this optimized structural design, the analyzer can provide a more stable and efficient operating experience in complex laboratory environments.

[0036] Specifically, in some embodiments, the support component 300 can move to the first position and the second position under the drive of the drive component 400. The support component 300 is partially connected to the slider 600. In the first position, the support component 300 drives the slider 600 to move in the direction extending out of the inlet 110 and compresses the elastic member 800. In the second position, the support component 300 drives the slider 600 to move in the direction retracting from the inlet 110 and the elastic member 800 rebounds. This design allows the support component 300 to perform multifunctional operations in different positions. In the first position, the support component 300 drives the slider 600 to move in the direction extending out of the inlet 110 while compressing the elastic member 800. This process not only ensures the stable movement of the slider 600, but also provides additional cushioning and stability through the compression of the elastic member 800, reducing the impact and wear that may be caused by sudden movement. When the supporting component 300 moves to the second position, the slider 600 moves in the direction of the retraction inlet 110. At this time, the rebound effect of the elastic element 800 is manifested, and the rebound of the elastic element 800 can help the slider 600 return to its original position smoothly.

[0037] Specifically, such asFigure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the support assembly 300 includes a support plate 310 and a guide recess 320 connected to the support plate 310. The support plate 310 supports the reagent tray 900, and the guide recess 320 is slidably engaged with the guide rod 700. The design of the support assembly 300 includes the support plate 310 and the guide recess 320 connected to the support plate 310. The main function of the support plate 310 is to support the reagent tray 900, which is crucial for sample handling during experiments and analyses. The guide recess 320 on the support plate 310 allows the support plate 310 to be slidably engaged with the guide rod 700. This design, through the cooperation of the guide recess 320 and the guide rod 700, provides a stable and controllable movement path, enabling the support assembly 300 to maintain precise positioning and smooth sliding during movement. The presence of the guide recess 320 not only ensures the stability of the support assembly 300 but also reduces errors and mechanical wear that may be caused by improper movement. Through this structural design, the microfluidic chemiluminescence analyzer 10 can achieve high-precision chip positioning and processing during operation, ensuring the accuracy and repeatability of experimental results.

[0038] Specifically, such as Figure 2 As shown, in some embodiments, the number of each of the connecting rod assembly 500 and the slider 600 is set to two, and they correspond one-to-one. The two connecting rod assemblies 500 are respectively located on the left and right sides of the support plate 310. The number of guide recesses 320 is also set to two, and the two guide recesses 320 are respectively located on the left and right sides of the support plate 310. One guide recess 320 is slidably engaged with one guide rod 700, and the other guide recess 320 is slidably engaged with the other guide rod 700. This configuration is designed to enhance the stability and symmetry of the system. Specifically, the two connecting rod assemblies 500 are respectively located on the left and right sides of the support plate 310. This symmetrical design helps to maintain balance during operation and reduces the risk of offset or tilting. Each of the left and right sides of the support plate 310 has a guide recess 320, and each guide recess 320 is used in conjunction with a guide rod 700. In this way, one guide recess 320 can be slidably engaged with one guide rod 700, while the other guide recess 320 engages with another guide rod 700. This dual-guide design not only improves the movement accuracy of the support component 300 but also enhances the stability of the overall structure. Through this arrangement, the support component 300 can maintain a smooth and precise movement path during movement, ensuring the accurate positioning of the reagent tray 900 during the experiment. This design not only improves the operational performance of the equipment but also reduces experimental deviations caused by mechanical errors, thereby improving the reliability and repeatability of experimental results.

[0039] Specifically, such as Figure 3 As shown, in some embodiments, the support plate 310 has an adapter groove 311 on the side facing the inlet 110, and the reagent tray 900 is disc-shaped and at least partially extends into the adapter groove 311. In these embodiments, the design of the support plate 310 is carefully adjusted to accommodate reagent trays 900 of different diameters. Specifically, the support plate 310 has an adapter groove 311 on the side facing the inlet 110, which is designed to allow the reagent tray 900 to partially extend into it, thereby achieving stable placement and positioning. The reagent tray 900 is designed to be disc-shaped, a shape that facilitates rotation and fixation within the adapter groove 311. The flexible design of the adapter groove 311 allows for the adaptation of disc-shaped reagent trays 900 of different diameters, greatly increasing the versatility and applicability of the structure. With this design, users can use reagent trays 900 of different sizes in the same device without changing the device or making complex adjustments. To achieve adaptation to reagent trays 900 of different diameters, the entry and exit position of the support plate 310 can be adjusted according to the size of the reagent tray 900. Specifically, when using a smaller reagent tray 900, the infeed structure moves forward accordingly to ensure that the reagent tray 900 can correctly enter the adapter slot 311 and remain stable. This flexible drive structure design ensures that the device can always maintain efficient and accurate operation when handling reagent trays 900 of different sizes.

[0040] Specifically, such as Figure 4As shown, in some embodiments, the door 200 is provided with two limiting protrusions 210 extending inward along the inlet 110. The two limiting protrusions 210 are respectively connected to both sides of the door 200 and are used to limit the reagent tray 900. In these embodiments, to ensure the stability and accurate positioning of the reagent tray 900 within the compartment, the door 200 is designed with two limiting protrusions 210. These two limiting protrusions 210 are arranged inward along the inlet 110, located on both sides of the door 200. The main function of the limiting protrusions 210 is to provide lateral support and positioning for the reagent tray 900. When the reagent tray 900 is placed inside the compartment, the limiting protrusions 210 can effectively restrict its lateral movement, preventing displacement or shaking during operation. This design not only improves the stability of the reagent tray 900 but also ensures accuracy and safety during equipment operation. By connecting the limiting protrusions 210 to both sides of the door 200, the entire structure achieves effective limiting of the reagent tray 900. This design simplifies the placement process of the reagent tray 900, allowing users to quickly and accurately place it into the compartment without additional adjustments or securing it. Furthermore, this limiting design offers flexibility, accommodating reagent trays 900 of different sizes. The position and height of the limiting protrusion 210 can be adjusted according to the specific specifications of the reagent tray 900, thus meeting various experimental needs.

[0041] Specifically, such as Figure 2 As shown, in some embodiments, the drive assembly 400 includes a motor 410 and a timing belt 420, one end of the timing belt 420 being connected to the output shaft of the motor 410, and the other end of the timing belt 420 being connected to the carrier assembly 300.

[0042] Specifically, such as Figure 4As shown, in some embodiments, the linkage assembly 500 includes a first linkage 510 and a second linkage 520. One end of the first linkage 510 is rotationally connected to the slider 600, and the other end of the first linkage 510 is rotationally connected to one end of the second linkage 520. The other end of the second linkage 520 is connected to the door 200. This linkage assembly 500 is composed of the first linkage 510 and the second linkage 520, and through a clever connection method, it ensures the smooth movement of the door 200. Specifically, one end of the first linkage 510 is rotationally connected to the slider 600, and this connection allows the first linkage 510 to rotate with the movement of the slider 600. The other end of the first linkage 510 is rotationally connected to one end of the second linkage 520, which allows flexible transmission of motion between the two linkages. The other end of the second linkage 520 is connected to the door 200, which means that when the slider 600 moves, the door 200 can be opened or closed accordingly through the transmission of the linkage assembly 500. The advantage of this design is that the rotational movement of the door 200 can be controlled through the linear movement of the slider 600 to achieve the opening and closing of the door 200. This design of the linkage assembly 500 not only makes the operation of the door 200 smoother and more reliable, but also reduces friction and wear, improving the durability of the equipment. In addition, by adjusting the length and connection angle of the linkages, the opening angle and speed of the door 200 can be precisely controlled to meet different operation requirements. In summary, this design of the linkage assembly 500 provides an efficient mechanical transmission solution while realizing the automatic control of the door 200, improving the performance and user experience of the overall equipment.
