Description

Technical Field

[0001] The present invention relates to the technical field of cell protein analysis, and in particular to a fully automatic protein analysis system. Background Art

[0002] The detection and analysis of specific proteins has important clinical significance for disease diagnosis. Currently, the most commonly used detection principle is immunoturbidimetry. Over thousands of plasma proteins have been discovered, with hundreds of the more important ones varying in size and content, each performing distinct functions. Clinically, dozens of plasma proteins are commonly used. These proteins possess strong antigenicity and can bind to antibody molecules with corresponding antigenic determinants. They can be found in body fluids such as blood, cerebrospinal fluid, and urine. These proteins are referred to as "specific proteins," and their quantitative detection provides an important basis for clinical diagnosis, therapeutic efficacy assessment, and prognosis analysis.

[0003] Due to the development of protein detection technology and the expansion of its clinical application, immunoturbidimetric analyzers have become a common clinical testing equipment purchased by domestic laboratories in recent years. In this type of analyzer, the method of adding samples and reagents to a reaction dish on a rotatable reaction vessel via a sample needle, and then measuring the absorbance of the reaction liquid in the reaction dish via a light detector is becoming increasingly mainstream. However, in actual use, specific proteins in some reaction dishes can be detected directly after adding reagents, while specific proteins in other reaction dishes may need to be pre-treated by dilution or initial incubation before subsequent reagent addition and detection. This results in low detection efficiency of specific proteins in the reaction vessel, which in turn affects the automated analysis efficiency of the entire machine. Summary of the Invention

If the specific posture changes, the directional indication will also change accordingly.

[0035] See also Figures 1-6 , an embodiment of the present invention provides a fully automatic protein analysis system, comprising:

[0036] The analysis module includes a detection assembly and a rotatable reaction disk a1. The reaction disk a1 is provided with a plurality of reaction vessels a11 distributed along the circumference. The detection assembly includes at least one of a transmission light detector and a scattered light detector. The detection assembly is positioned directly opposite the reaction vessels a11.

[0037] The sampling module includes a rotating first sampler b2 and a rotatable sample tray b1. The sample tray b1 is provided with several sample dishes b11. Both the sample dishes b11 and the reaction dishes a11 are located in the rotation path of the first sampler b2. The first sampler b2 is used to aspirate samples from the sample dishes b11 and discharge them into the reaction dishes a11.

[0038] The dilution module includes a dilution tray c3 for storing diluent, a rotating second sampler c4, and a rotatable mixing tray c1. The mixing tray c1 is provided with a plurality of mixing dishes c11. The dilution tray c3 and the mixing dishes c11 are located in the rotation path of the second sampler c4. The mixing dishes c11 are located in the rotation path of the first sampler b2.

[0039] The reagent dispensing module includes a reagent dispensing device d2 and a rotatable reagent disk d1. The reagent disk d1 is provided with a plurality of reagent dishes d11. The reagent dispensing device d2 is used to absorb the reagents in the reagent dishes d11 and discharge them into the reaction dish a11.

[0040] The first sampler b2, the second sampler c4 and the reagent extractor d2 in the above scheme are preferably liftable sampling needles, and are driven to rotate by a motor, so that the operation is simple and the operation is reliable; compared with the existing technology, the above scheme integrates the sampling module, dilution module and reagent extractor module around the analysis module, thereby realizing a fully automated process of sampling, dilution, reagent addition, analysis and detection of the samples to be tested, avoiding the contamination problem caused by manual intervention, and at the same time, the user can adjust whether to transfer the sample directly to the reaction dish a11 or to dilute and culture the sample before transferring it to the reaction dish a11 through a preset program, effectively improving the culture and detection efficiency of the whole machine and having good practicality.

[0041] In this embodiment, the upper end surface of the reaction disk a1 is provided with a plurality of slots a12 arranged along the circumferential direction, and the reaction dish a11 is inserted into the slots a12. Each slot a12 is provided with an elastic clip a4 for abutting against the reaction dish a11, and the side wall of each slot a12 is provided with an observation hole a13 that penetrates to the outer wall of the reaction disk a1. The detection component is arranged toward the observation hole a13, so that on the one hand, the detection component can more accurately detect the sample in the reaction dish a11 through the observation hole a13, reducing light loss. On the other hand, when necessary, the reaction dish a11 can be pulled out of the slot a12 to achieve separation, which is convenient for replacement.

[0042] Furthermore, the upper end surface of the reaction disk a1 is provided with a plurality of circumferentially arranged through slots a14. The through slots a14 are radially arranged and correspond to the slots a12 one by one. The through slots a14 extend between the groove wall of the slots a12 and the outer wall of the reaction disk a1. One side of the elastic clip a4 is connected to the slot a12, and the other side is arc-shaped and arranged radially along the reaction disk a1, thereby achieving elastic abutment against the reaction vessels a11 in the radial direction. The provision of the through slots a14 allows the reaction disk a1 to appropriately elastically deform circumferentially, thereby ensuring a more stable connection between the reaction vessels a11 and the reaction disk a1 and more convenient assembly and disassembly.

[0043] Furthermore, the groove wall of each slot a12 is provided with two radially arranged embedding grooves, and the two embedding grooves are respectively located on both sides of the through groove a14 corresponding to the same slot a12. Each embedding groove corresponds to an elastic clip a4, and one side of the elastic clip a4 is engaged in the embedding groove and the other side is in contact with the reaction dish a11, thereby achieving a better fixing effect on the reaction dish a11.

[0044] As an extension of this embodiment, the analysis module also includes a support frame a2, which is provided with an annular receiving groove a21. The reaction disk a1 is annular and rotatably connected to the interior of the receiving groove a21. A mounting base is removably connected to the outer wall of the receiving groove a21, and the detection assembly is connected to the mounting base. With this structure, the receiving groove a21 creates a relatively stable incubation environment for the reaction disk a1, and the installation of the mounting base facilitates the installation and adjustment of the detection assembly. In this embodiment, the mounting base includes a first base a31 and a second base a32 arranged along the circumference of the accommodating groove a21, and the detection module includes two scattered light detectors and a transmissive light detector. The two scattered light detectors are respectively connected to the upper and lower parts of the first base a31. A light path is provided on the side of the first base a31 facing the observation hole a13, and the light path is connected to the two scattered light detectors, so that the accuracy of subsequent detection and analysis is effectively improved by taking the average of the parameters detected by the two scattered light detectors; the transmissive light detector is connected to the second base a32 and is arranged toward the observation hole a13, so as to realize accurate detection of the transmitted light of the reaction dish a11.

[0045] In addition, the support frame a2 is also provided with a temperature adjustment component and a humidity adjustment component (not shown in the figure). The temperature adjustment component is used to adjust the temperature inside the receiving tank a21, and the humidity adjustment component is used to adjust the humidity inside the receiving tank a21, so that the reaction dish a11 can perform a culture reaction in a specific environment.

[0046] like Figure 8 As shown, in this embodiment, the dilution plate c3 is provided with a plurality of detachable dilution dishes c31, and the dilution dishes c31 are arranged along the direction of the rotation path of the second sampler c4, so that the second sampler c4 can add the diluent to the mixing dish c11 to achieve dilution and mixing.

[0047] Furthermore, the dilution module further comprises an assembly tray c2, which is detachably placed above the mixing tray c1. The mixing dish c11 is fan-shaped, and the upper end surface of each mixing dish c11 is provided with a plurality of liquid storage tubes c12. The assembly tray c2 is provided with a plurality of female plug-ins c21 arranged along the circumferential direction, and the mixing dish c11 is provided with a sub-plug-in c13 for matching to the female plug-in c21, so that a single mixing dish c11 can be directly taken out, and all mixing dishes c11 can be directly taken out at once through the assembly tray c2, which is simple and convenient to operate and has good practicality. In the present embodiment, the female plug-in c21 is a raised column, and the sub-plug-in c13 is a through hole, so that the detachable connection between the mixing dish c11 and the assembly tray c2 can be achieved by plugging, and the connection is reliable and easy to operate. Of course, the female plug-in c21 and the sub-plug-in c13 can also be replaced with other common connection methods, such as buckle connection or clamping, which is not limited by the present design. The middle part of the assembly tray c2 is also provided with a handle for holding, so as to further facilitate user operation.

[0048] As an extension of this embodiment, it also includes a cleaning module positioned toward the reaction vessel a11 and a power source e1 for driving the cleaning module up and down. The power source e1 is preferably a vertically arranged ball screw motor pair, which allows for smoother and more accurate operation. The cleaning module includes a plurality of cleaning components e2, a plurality of water washing components e3, and a suction component e4, which are arranged in sequence. The cleaning component e2 includes a first nozzle e21 for spraying cleaning liquid onto the reaction vessel a11 and a first suction pipe e22 for absorbing liquid from the reaction vessel a11. The water washing component e3 includes a second nozzle e31 for spraying water onto the reaction vessel a11 and a second suction pipe e32 for absorbing liquid from the reaction vessel a11. The suction component e4 is used to suck liquid from the reaction vessel a11, thereby effectively cleaning the reaction vessel a11 and improving cleaning efficiency. In addition, the number of cleaning components e2, water washing components e3, and suction components e4 can be set as needed. In this embodiment, there are four cleaning components e2 and two water washing components e3.

[0049] Furthermore, the suction component e4 includes a third suction pipe e41, and the lower part of the third suction pipe e41 is provided with a guide block e42 for extending into the interior of the reaction vessel a11. The lower end of the guide block e42 is provided with an air hole connected to the third suction pipe e41. The cross-sectional shape of the guide block e42 is similar to the cross-sectional shape of the reaction vessel a11, but the cross-sectional size of the guide block e42 is smaller than the cross-sectional size of the reaction vessel a11, so that a gap is left between the outer side surface of the guide block e42 and the inner wall of the reaction vessel a11 to form an air duct, ensuring that the suction component e4 can completely suck out the residual liquid in the reaction vessel a11.

[0050] like Figure 7 As shown, in another embodiment, the bottom of the guide block e42 is provided with a plurality of downwardly protruding guide cones e43. The upper ends of the guide cones e43 are positioned toward the air holes, and the lower ends of the guide cones e43 are configured to abut against the top corners of the bottom of the reaction vessel a11. For example, in this embodiment, the cross-section of the reaction vessel a11 is square, and the bottom of the reaction vessel a11 has four top corners. Therefore, there are preferably four guide cones e43, and the four guide cones e43 abut against each of the four top corners of the reaction vessel a11. Thus, when the third suction tube e41 is suctioning, the residual liquid in the reaction vessel a11 can flow along the guide cones e43 into the air holes, further improving the suction effect.

[0051] In other embodiments, the cleaning module also includes a connecting frame, and the cleaning component e2, the water washing component e3 and the suction component e4 are all slidably connected to the connecting frame. The connecting frame is provided with a spring for pushing the cleaning component e2, the water washing component e3 and the suction component e4 toward the reaction dish a11, so that the cleaning component e2, the water washing component e3 and the suction component e4 can form a certain sliding buffer margin relative to the reaction dish a11 to reduce the probability of damage. At the same time, it also enables the cleaning component e2, the water washing component e3 and the suction component e4 to penetrate deeper into the reaction dish a11, thereby achieving a better cleaning effect on the bottom of the reaction dish a11. It should be noted that the specific arrangement of the springs can be designed as needed. For example, there can be multiple springs, with at least one spring corresponding to each cleaning assembly e2, water-washing assembly e3, and suction assembly e4. Taking cleaning assembly e2 as an example, the upper end of the spring corresponding to cleaning assembly e2 is connected to the connecting frame, and the lower end of the spring corresponding to cleaning assembly e2 is connected to the middle of the first suction pipe e22 and the first nozzle e21. Therefore, when the lower ends of the first suction pipe e22 and the first nozzle e21 are inserted deeply into the reaction vessel a11 and contact the bottom of the reaction vessel a11, the cleaning assembly e2 will be able to slide upward relative to the connecting frame. After the deep cleaning is completed, the spring corresponding to cleaning assembly e2 drives the cleaning assembly e2 to return to its original position relative to the connecting frame. The arrangement of the springs corresponding to the water-washing assembly e3 and the suction assembly e4 is similar and will not be further described here.

[0052] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. For those skilled in the art, various changes and modifications can be made without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
