Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic equipment, and in particular to an analytical equipment. Background Art

[0002] The fully automatic immunoassay analyzer can perform quantitative or qualitative detection of target analytes such as antibodies and antigens contained in blood samples to be tested. Usually, the sample to be tested and reagents (or reactants) are added to an empty reactor and after mixing, incubation and washing and separation (Bound-free, binding separation, i.e. BF separation, sometimes referred to as washing in this article), signal reagents are added to the reactor to measure optical signals or electrical signals, thereby realizing the measurement and analysis of the target analytes contained in the sample to be tested.

[0003] In a fully automatic chemiluminescence immunoassay, in order to achieve the separation of free markers and immune complex markers, it is usually necessary to undergo a cleaning separation to remove the unbound components in the reactants (mainly free labeled antigens or antibodies), and then complete the luminescent reaction based on the immune complex containing the marker. Each stage of cleaning separation includes aspiration (absorb the unbound components in the reactants in the reaction cup, i.e., aspiration of waste liquid) and injection (injection of cleaning buffer into the reaction cup after aspiration of waste liquid). In order to ensure the effect of cleaning separation and the accuracy of the test results, during or after the injection of liquid during cleaning separation, various mixing methods such as a mixing cup mechanism are required to shake and disperse the reactants in the reaction cup.

[0004] As can be seen from the above, the fully automatic immunoassay analyzer in the prior art mainly includes a frame and a measuring disc mechanism, a waste liquid suction mechanism, a liquid injection mechanism, a mixing and grabbing mechanism and other mechanisms installed above the frame; the waste liquid suction mechanism, the liquid injection mechanism, the mixing and grabbing mechanism and other mechanisms are arranged around the measuring disc mechanism, and the overall structure of the fully automatic immunoassay analyzer is relatively complex. At present, the waste liquid suction mechanism is usually installed on the top plate of the frame or on the top cover of the measuring disc mechanism; when the waste liquid suction mechanism is installed on the top plate of the frame, the waste liquid suction mechanism needs to occupy the space on the side of the measuring disc mechanism, affecting the layout of other adjacent mechanisms on the frame; when the waste liquid suction mechanism is installed on the top plate of the measuring disc mechanism, the waste liquid suction mechanism needs to occupy the space above the measuring disc mechanism, increasing the risk of interference between the waste liquid suction mechanism and the cup gripping hand assembly of the mixing and grabbing mechanism located above the measuring disc mechanism. Summary of the invention

[0005] In view of this, the present invention provides an analysis device to solve the technical problems that the waste liquid suction mechanism occupies a large space, affects the layout of other mechanisms on the rack, or easily interferes with the cup gripper assembly above the optical disc measuring mechanism.

[0006] In order to solve at least one of the above technical problems, the technical solution of the present invention is as follows:

[0007] An analysis device comprising:

[0008] A support frame, comprising a mounting base plate disposed above a rack;

[0009] The optical disc measuring mechanism comprises a storage body located above the installation base plate and an optical disc measuring device rotatably arranged in the storage body; an installation space is formed between the storage body and the frame;

[0010] The waste liquid suction mechanism comprises a mounting bracket, a driving member, a lifting assembly and a waste liquid suction assembly; the mounting bracket is fixedly connected to the mounting base plate, the driving member is mounted on one side of the mounting bracket and is at least partially located in the mounting space below the bin body; the lifting assembly is located outside the side wall of the bin body and is driven by the driving member to perform lifting motion, the waste liquid suction assembly is connected to the lifting assembly, the waste liquid suction assembly is located directly above the measuring disc and is provided with a waste liquid needle for absorbing waste liquid in the measuring disc.

[0011] By adopting the above technical solution, the mounting bracket of the waste liquid suction mechanism is fixed on the mounting base plate, and the driving part installed on one side of the mounting bracket is located in the mounting space between the optical disc measuring mechanism and the frame, and only the waste liquid needle of the waste liquid suction component is located above the optical disc measuring mechanism. Not only can the normal waste liquid suction function be achieved through the lifting and lowering movement of the waste liquid suction component, but also the occupation of the side space and top surface space of the optical disc measuring mechanism by the waste liquid suction mechanism is reduced, which is convenient for the layout of other mechanisms on the frame, and also convenient for the waste liquid suction component to avoid other components above the optical disc measuring mechanism. In addition, the waste liquid suction mechanism and the optical disc measuring mechanism are integrated together to realize the modular design of the two, reducing the difficulty of debugging the positions of subsequent mechanisms; and the convex parts on the top surfaces of the frame and the optical disc measuring mechanism are small, which is convenient for the maintenance of the top surfaces of the frame and the optical disc measuring mechanism.

[0012] Furthermore, the mounting base plate is provided with a mounting surface for connecting with the mounting bracket, and the mounting bracket is located below the mounting surface.

[0013] By adopting the above technical solution, the entire waste liquid suction mechanism can be installed in a suspended manner.

[0014] Furthermore, the mounting bracket includes a top mounting plate and a main mounting plate; the top mounting plate is surface-connected to the mounting bottom plate, the main mounting plate is connected below the top mounting plate and is arranged perpendicular to the top mounting plate; the main mounting plate has a first mounting side facing the mounting space, and the drive member is mounted on the first mounting side.

[0015] Furthermore, the main mounting plate also has a second mounting side surface arranged opposite to the first mounting side surface; the waste liquid suction mechanism also includes a transmission assembly that is transmission-connected between the driving member and the lifting assembly, and the transmission assembly is located on the side of the mounting bracket facing away from the driving member.

[0017] By adopting the above technical scheme, the motor drives the sliding seat and the lifting assembly to perform lifting movement along the guiding direction of the linear guide rail by driving the swing arm to swing, so that the motor can be installed horizontally on the mounting bracket. Compared with the vertical installation method of the motor in the traditional waste liquid suction mechanism, the overall height of the waste liquid suction mechanism can be reduced, and the requirement for the installation height of the waste liquid suction mechanism can be reduced; compared with the method of using a worm gear transmission mechanism to achieve lifting with a horizontal motor, there is no need to manufacture a worm gear transmission mechanism with higher manufacturing cost, which is conducive to cost saving, and the guide groove can limit the lifting and lowering movement stroke of the sliding seat and the lifting assembly through the force transmission member, and there is no need to additionally design a lifting stroke limit mechanism, and the structure is simpler.

[0018] Furthermore, the force transmission member is a roller rotatably arranged around its own axis, the guide groove is a strip groove, and the roller and the strip groove are in rolling cooperation.

[0019] By adopting the above technical solution, the force transmission member adopts the form of rolling cooperation between the roller and the strip groove on the sliding seat, which can reduce the friction resistance between the roller and the sliding seat, and the operation of the lifting component is smoother.

[0020] Furthermore, the lifting assembly includes a support rod seat fixedly connected to the sliding seat, and a support rod fixed to the support rod seat and hollow inside; the waste liquid suction assembly includes a cantilever detachably connected to the support rod and with one end extending directly above the measuring optical disc, and a liquid guide tube passing through the inside of the support rod, and the waste liquid needle is installed below the cantilever and connected to the liquid guide tube.

[0021] By adopting the above technical solution, the structure in which the catheter passes through the inside of the support rod has good overall compactness.

[0022] Furthermore, the cantilever is provided with a top cover which is arranged above the cantilever.

[0023] Furthermore, the measuring disc mechanism also includes a measuring disc driving assembly for driving the measuring disc to rotate around its own axis in the bin body; the measuring disc driving assembly is installed below the mounting base plate.

[0024] By adopting the above technical solution, the optical disc drive assembly is installed under the mounting base. Compared with the traditional optical disc drive assembly installed under the rack, the installation space between the mounting base and the rack can be further fully utilized, which is conducive to realizing the overall compact design of the analysis equipment.

[0025] Furthermore, a plurality of placement slots for placing reaction cups are provided above the measuring optical disc, a side wall of the measuring optical disc is provided with a photometric hole corresponding to each of the placement slots, and an optical signal measuring component for measuring the luminescence amount of the reactant in the reaction cup through the photometric hole is fixed on the side wall of the chamber body.

It should be noted that Figure 1The lower end surfaces of the plurality of vertical rods 12 are the top surfaces of the frame.

[0037] like Figure 1 As shown, the measuring disc mechanism 2 includes a chamber 21 located above the mounting base plate 11, a measuring disc (not shown) rotatably arranged in the chamber 21, and a measuring disc top cover 23 covering the opening above the chamber 21.

The cup grabbing mechanism includes a cup grabbing hand assembly extending above the measuring disc mechanism 2, and the cup grabbing hand assembly is used to grab the reaction cup in the measuring disc and shake the reaction cup to fully mix the reactants in the reaction cup, and remove the reaction cup when necessary; the cup grabbing hand assembly moves in the space directly above the measuring disc. It should be noted here that the specific structures of the liquid injection mechanism and the cup grabbing mechanism are conventional designs well known to those skilled in the art, and are not closely related to the invention of this application, so they will not be described here in detail. The waste liquid suction mechanism 3 mainly protected by this application is described in detail below.

[0038] like Figure 1 As shown, in some embodiments, the bottom plate of the bin body 21 is fixed on the mounting bottom plate 11, a mounting space is formed between the bin body 21 and the frame, and the waste liquid suction mechanism 3 is fixed on the plate surface of the mounting bottom plate 11 extending outward relative to the peripheral side wall of the bin body 21. In other alternative embodiments, the bottom plate of the bin body 21 can be an integrated structure with the mounting bottom plate 11; or the mounting bottom plate 11 is fixed to the periphery of the bottom plate of the bin body 21.

[0039] like Figure 2 and Figure 3 As shown, the waste liquid suction mechanism 3 includes a mounting bracket 31, a driving member 32, a lifting assembly 33 and a waste liquid suction assembly 34. The mounting bracket 31 is fixedly connected to the mounting base plate 11; the driving member 32 is mounted on one side of the mounting bracket 31 and at least partially located in the mounting space below the bin body 21; the lifting assembly 33 is located outside the side wall of the bin body 21 and is driven by the driving member 32 to perform lifting motion; the waste liquid suction assembly 34 is connected to the lifting assembly 33, is located directly above the measuring disc and is provided with a waste liquid needle 341 for absorbing waste liquid in the measuring disc.

[0040] This analytical device, by fixing the mounting bracket 31 of the waste liquid suction mechanism 3 on the overhead mounting base plate 11, and the driving member 32 mounted on one side of the mounting bracket 31 is partially located in the mounting space between the bin body 21 and the frame, and only the waste liquid needle 341 of the waste liquid suction component 34 is located above the optical disc measuring mechanism 2, not only can the normal waste liquid suction function be achieved through the lifting and lowering movement of the waste liquid suction component 34, but also the occupation of the side space and top surface space of the optical disc measuring mechanism 2 by the waste liquid suction mechanism 3 is reduced, which is convenient for the layout of other mechanisms on the frame, and also convenient for the waste liquid suction component 34 to avoid other components above the optical disc measuring mechanism 2. In addition, the waste liquid suction mechanism 3 and the optical disc measuring mechanism 2 are integrated together, which can realize the modular design of the two and reduce the difficulty of debugging the positions of each mechanism in the future; and the outer protrusion on the top surface of the frame and the optical disc measuring mechanism 2 is small, which is convenient for the maintenance of the top surface of the frame and the optical disc measuring mechanism 2.

[0041] like Figure 1 As shown, the optical disc mechanism 2 also includes an optical disc drive assembly 22 for driving the optical disc to rotate around its own axis in the chamber body 21; the optical disc drive assembly 22 is installed below the mounting base plate 11. The optical disc drive assembly 22 is specifically a drive motor, which drives the central axis of the optical disc to rotate through a gear belt mechanism. The optical disc drive assembly 22 is installed below the mounting base plate 11. Compared with the conventional optical disc drive assembly 22 installed below the rack, the mounting space between the mounting base plate 11 and the rack can be further fully utilized, which is conducive to realizing the compact design of the overall analysis equipment.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting base plate 11 is provided with a mounting surface for connecting with the mounting bracket 31, and the mounting bracket 31 is located below the mounting surface; specifically, the mounting bracket 31 is fixedly connected to the mounting base plate 11 by a plurality of vertically arranged bolts; such an arrangement can realize the hanging installation of the entire waste liquid suction mechanism 3. In other alternative embodiments, the mounting base plate 11 can also be provided with a vertical bending plate that is bent vertically downward, and the mounting bracket 31 is fixed to the vertical bending plate of the mounting base plate 11 by a plurality of horizontally arranged bolts.

[0043] like Figure 2 and Figure 3As shown, in some embodiments, the mounting bracket 31 includes a top mounting plate 311 and a main mounting plate 312; the top mounting plate 311 is arranged horizontally, and the main mounting plate 312 is arranged vertically. The top surface of the top mounting plate 311 is the mounting surface where the mounting bracket 31 is connected to the mounting base plate 11, the top mounting plate 311 and the mounting base plate 11 are connected surface to surface, and the main mounting plate 312 is integrally connected below the top mounting plate 311 and is arranged perpendicular to the top mounting plate 311. Specifically, the mounting bracket 31 can be formed by bending a sheet metal part. The main mounting plate 312 has a first mounting side surface and a second mounting side surface that are arranged opposite to each other, the first mounting side surface and the second mounting side surface are the largest surfaces of the main mounting plate 312, and the areas of the first mounting side surface and the second mounting side surface are larger than the area of ​​the mounting surface on the top mounting plate 311.

[0044] like Figure 2 and Figure 3 As shown, the first mounting side of the main mounting plate 312 faces the mounting space below the bin body 21. The driving member 32 is specifically a motor, and the motor is transversely mounted on the first mounting side of the main mounting plate 312. The waste liquid suction mechanism 3 also includes a transmission assembly 35 that is transmission-connected between the driving member 32 and the lifting assembly 33, and the transmission assembly 35 is located on the side of the mounting bracket 31 facing away from the motor. In some embodiments, the transmission assembly 35 includes a swing arm 351 fixedly connected to the output shaft of the motor, a linear guide rail 353 fixed to one side of the mounting bracket 31, and a sliding seat 354 that is slidably connected to the linear guide rail 353 along the guide direction of the linear guide rail 353. The lifting assembly 33 is fixedly connected to the sliding seat 354, and the sliding seat 354 is provided with a guide groove 3541 located on one side of the swing arm 351. The end of the swing arm 351 away from the output shaft is provided with a force transmission member 352 extending into the guide groove 3541; when the swing arm 351 swings under the drive of the motor, the force transmission member 352 moves in the guide groove 3541 to drive the sliding seat 354 and the lifting assembly 33 to perform lifting and lowering movements along the guiding direction of the linear guide rail 353. With such arrangement, the motor drives the swing arm 351 to swing and drives the sliding seat 354 and the lifting assembly 33 to perform lifting motion along the guiding direction of the linear guide rail 353, so that the motor can be installed horizontally on the mounting bracket 31. Compared with the vertical installation of the motor in the traditional waste liquid suction mechanism, the overall height of the waste liquid suction mechanism can be reduced, and the requirements for the installation height of the waste liquid suction mechanism can be reduced; compared with the method of using a worm gear transmission mechanism to achieve lifting by a horizontal motor, there is no need to make a worm gear transmission mechanism with a high manufacturing cost, which is conducive to cost saving, and the guide groove 3541 can limit the lifting motion stroke of the sliding seat 354 and the lifting assembly 33 through the force transmission member 352, and there is no need to design an additional lifting stroke limit mechanism, and the structure is simpler. In other alternative embodiments, the transmission assembly 35 can also use a worm gear transmission mechanism, as long as the transmission assembly 35 can convert the rotational motion of the horizontal motor shaft into a vertical lifting motion.

[0045] like Figure 2 and Figure 3 As shown, the force transmission member 352 is a roller rotatably arranged around its own axis, and the guide groove 3541 is a strip groove, and the roller and the strip groove are rollingly matched. The force transmission member 352 adopts the form of rolling matching between the roller and the strip groove on the sliding seat 354, which can reduce the friction resistance between the roller and the sliding seat 354, making the operation of the lifting assembly 33 smoother.

[0046] like Figure 2 and Figure 3 As shown, the lifting assembly 33 includes a support rod seat 331 fixedly connected to the sliding seat 354, and a support rod 332 fixed to the support rod seat 331 and hollow inside. The waste liquid suction assembly 34 also includes a cantilever 342 detachably connected to the support rod 332 and one end of which extends directly above the measuring optical disc, and a liquid guide tube 343 passing through the inside of the support rod 332; the waste liquid needle 341 is installed below the cantilever 342 and communicates with the liquid guide tube 343. The lifting assembly 33 also includes a top cover 333 covered above the cantilever 342. The structural form in which the liquid guide tube 343 passes through the inside of the support rod 332 has good overall compactness. Further, the installation angle of the cantilever 342 on the support rod 332 is adjustable, and the cantilever 342 of different lengths can be detachably connected to the support rod 332, so that the waste liquid suction of the reaction cups at different positions can be realized, thereby improving the versatility of the waste liquid suction mechanism 3. The portion where the top outlet of the waste liquid needle 341 is connected to the liquid guiding tube 343 is bent at 90 degrees to reduce the height of the waste liquid needle 341. The lifting assembly 33 also includes a top cover 333 disposed above the cantilever 342, and the top cover 333 is used to protect the exposed portion of the waste liquid needle 341 and the liquid guiding tube 343 above the cantilever 342.

[0047] In summary, the analytical device provided by the present invention reduces the occupation of the side space and top space of the optical disc measuring mechanism 2 by the waste liquid suction mechanism 3 by fixing the mounting bracket 31 of the waste liquid suction mechanism 3 on the mounting base 11, facilitates the layout of other mechanisms on the rack, and also facilitates the waste liquid suction component 34 to avoid other components above the optical disc measuring mechanism 2. In addition, the waste liquid suction mechanism 3 and the optical disc measuring mechanism 2 are integrated together to realize the modular design of the two, reducing the difficulty of debugging the positions of each subsequent mechanism.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
