Description

Technical Field

[0001] This utility model relates to the field of testing instruments, and in particular to a cleaning structure for a chemiluminescence analyzer. Background Technology

[0002] A chemiluminescence analyzer is an analytical instrument used in basic medical fields. It can perform fully automated image acquisition and qualitative and quantitative analysis on samples such as protein electrophoresis, nucleic acid electrophoresis, blot membranes, X-ray films, tissue sections, microplates, and culture dishes.

[0003] Taking the design proposal CN105628687B, entitled "A Fully Automated Chemiluminescence Analyzer," as an example, the chemiluminescence analyzer mainly includes a robotic arm module, a cooling module, a power supply module, a reagent sample tray, a sampling needle assembly, a stirring assembly, a reaction cup rack, an incubation device, a magnetic separation assembly, a cleaning station assembly, and a measuring chamber. In actual use, during sample tube movement, liquid may leak from the sample tube opening and remain on the outer wall of the sample tube. Simultaneously, this leaked liquid may also condense on the inner wall of the sample perforation used to hold the sample tube. This liquid adhesion to the outer wall of the sample tube and the inner wall of the sample perforation leads to contamination of the experimental equipment and significantly increases the difficulty of cleaning these surfaces. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning structure for a chemiluminescence analyzer that can simultaneously clean the inner wall surface of the sample perforation and the outer surface of the sample tube, thereby effectively improving the cleaning efficiency of the analyzer.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cleaning structure for a chemiluminescence analyzer, including an analyzer body, a pull-out sample rack slidably disposed inside the analyzer body, pull-out sample rack through holes evenly disposed on the pull-out sample rack, and a synchronous cleaning mechanism, the synchronous cleaning mechanism including a sample placement plate disposed above the pull-out sample rack, the sample placement plate surface being provided with sample perforations for placing sample tubes, the sample perforations corresponding to the pull-out sample rack through holes; the synchronous cleaning mechanism including a cleaning component disposed below the pull-out sample rack, the cleaning layer of the cleaning component passing upward through the pull-out sample rack through holes to clean the inner wall surface of the sample perforations and the outer surface of the sample tubes.

[0006] Furthermore, the cleaning components include a base plate and support rods. The base plate is circular, and the support rods are evenly arranged around the top surface of the base plate. The cleaning layer is a hollow cylindrical structure, and the bottom of the cleaning layer is fixedly mounted on the support rods.

[0007] Furthermore, the cleaning components include a push plate and a spiral rod. The spiral rod is screwed into the push plate through a spiral hole, and the top of the spiral rod is fixedly connected to the center of the base plate.

[0008] Furthermore, it includes a stabilizing ring, which is rotatably connected to the base plate via a bearing body. The through hole of the pull-out sample holder is inverted T-shaped, and the stabilizing ring is fixedly installed in the bottom groove of the through hole of the pull-out sample holder.

[0009] Furthermore, the bottom of the pull-out sample holder is provided with an inwardly recessed groove, and the push plate is disposed in the groove at the bottom of the pull-out sample holder; it includes a limiting component, which includes a limiting plate and a limiting slider. The limiting slider is fixedly disposed on the side wall of the groove, the limiting plate is disposed on the top surface of the push plate, and a rectangular sliding hole is provided in the limiting plate. The extension direction of the rectangular sliding hole is perpendicular to the push plate, and the limiting slider is slidably disposed in the rectangular sliding hole.

[0010] Furthermore, the limiting slider is T-shaped, and the limiting slider is snapped into the rectangular sliding hole to prevent the limiting slider from falling off the rectangular sliding hole during the sliding process.

[0011] Furthermore, a pull ring is fixedly installed at the bottom of the push plate.

[0012] Furthermore, the synchronous cleaning mechanism includes a stabilizing component disposed above the sample placement plate for stabilizing the sample tube; the stabilizing component includes a pad horizontally mounted on the upper surface of the sample placement plate, the surface of the pad having a circular hole for the sample tube to pass through, and a metal spring for clamping the sample tube being disposed on the outer circumference of each circular hole, and a spherical clamping block being disposed on the upper end of the metal spring.

[0013] Furthermore, the side of the pad is provided with an inner arc-shaped strip, and the sample placement plate is provided with an outer arc-shaped clamping plate corresponding to the position of the inner arc-shaped strip, with the inner arc-shaped strip being clamped and set inside the outer arc-shaped clamping plate.

[0014] Furthermore, the pull-out sample holder is slidably disposed within the measuring groove of the main body of the measuring instrument, and a sealing ring is provided on the inner surface of the pull-out sample holder. The sealing ring is used to seal the measuring groove from the outside when the pull-out sample holder is pushed into the measuring groove.

[0015] The beneficial effects of this utility model are as follows: 1. By setting a sample placement plate above the pull-out sample rack, the sample tube can be stably placed on the sample placement plate. The outer surface of the sample tube is placed inside the sample perforation, and the gap between the inner wall of the sample perforation and the outer surface of the sample tube is the working space for the cleaning layer. After the cleaning layer is placed in the gap, it cleans both the inner wall of the sample perforation and the outer surface of the sample tube simultaneously. While cleaning the outer surface of the sample tube, it also efficiently cleans the inner wall of the sample perforation, which was originally difficult to clean. 2. By evenly arranging several support rods around the top surface of the base plate, a circumferentially evenly arranged support structure is formed. The bottom of the hollow cylindrical cleaning layer is fixed, and the top of the hollow cylindrical cleaning layer is placed in the gap between the inner wall of the sample perforation and the outer surface of the sample tube. The cleaning layer then cleans by rotating, improving cleaning efficiency. At the same time, it allows the cleaning layer to quickly position itself in the corresponding cleaning working space, providing a foundation for the batch cleaning of sample tubes. Third, the spiral connection between the twisted rod and the push plate allows the push plate to be manually driven while its linear motion is converted into the rotation of the twisted rod, thereby driving the cleaning layer to achieve cleaning through rotation, making cleaning more convenient and controllable. Fourth, the stabilizing components prevent the sample tube from rotating with the cleaning layer during the cleaning process, ensuring the cleaning is carried out effectively. This invention is particularly suitable for chemiluminescence analyzers. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 9 The cleaning structure of the chemiluminescence analyzer shown includes an analyzer body 100, inside which a pull-out sample holder 102 for placing sample tubes is slidably disposed. A synchronous cleaning mechanism 200 is provided on the pull-out sample holder 102. This mechanism cleans the liquid flowing out during sample tube movement without affecting the detection process, preventing the liquid from condensing and adhering to the sample placement plate 201, thus ensuring the cleanliness of the sample perforations 205. Multiple sample perforations 205 can be cleaned simultaneously. Compared to cleaning each perforation individually, this saves time and reduces cleaning difficulty. The inner walls of the pull-out sample holder through holes 105 on the surface of the pull-out sample holder 102 can be cleaned simultaneously with the inner walls of the sample perforations 205. The synchronous cleaning mechanism 200 includes a sample placement plate 201 placed on the upper surface of the pull-out sample holder 102. The sample placement plate 201 has several sample perforations 205 on its surface, with one sample tube placed in each perforation 205. The lower surface of the pull-out sample holder 102 is provided with a cleaning component 202 for cleaning the inner wall of the sample perforation 205 and the outer surface of the sample tube. The cleaning component 202 can be rotated to clean the inner wall of the sample perforation 205 and can also absorb the outflowing liquid.

[0028] The pull-out sample holder 102 has inwardly recessed rectangular grooves on both its upper and lower surfaces. The cleaning component 202 includes a push plate 2021 installed in the rectangular groove on the lower surface. The cleaning component 202 also includes a stabilizing ring 2024 installed in the through hole 105 of the pull-out sample holder. The through hole 105 of the pull-out sample holder has an inverted T-shaped structure, consisting of a circular groove at the bottom and a through hole extending upward from the circular groove. The stabilizing ring 2024 is disposed in the circular groove at the bottom. A base plate 2025 is rotatably disposed inside the stabilizing ring 2024, and the stabilizing ring 2024 supports the base plate 2025. The base plate 2025 supports the bottom of the sample tube, and multiple support rods 2028 extending into the sample perforation 205 are arranged circumferentially on the upper surface of the base plate 2025. Multiple support rods 2028 form a cage for the cleaning layer 2029, providing support for the cleaning layer 2029 without affecting the cleaning of the inner wall of the sample perforation 205. In other words, the cleaning layer 2029 fits snugly against the inner wall of the sample perforation 205 on the support rods 2028. A bearing body 2026 is embedded between the base plate 2025 and the stabilizing ring 2024. The bearing body 2026 provides support for the base plate 2025 without affecting its rotation. A twisted rod 2027 is positioned at the center of the lower surface of the base plate 2025. A spiral hole 2023 is formed on the surface of the push plate 2021 to engage with the twisted rod 2027. The twisted rod 2027 and the spiral hole 2023 work together, allowing the twisted rod 2027 to rotate as the push plate 2021 moves. The twisted rod 2027 can be a metal rod processed into a spiral or twisted shape using a twisting process. In summary, the cleaning layer 2029 is fitted onto the cage formed by the support rod 2028. When the sample placement plate 201 is installed on the upper surface of the pull-out sample holder 102, the cage formed by the cleaning layer 2029 and the support rod 2028 extends through the through hole 105 of the pull-out sample holder and into the sample perforation 205, with the cleaning layer 2029 adhering to the inner wall of the sample perforation 205. When the sample tube is placed in the sample perforation 205, the inner circumferential surface of the cleaning layer 2029 adheres to the outer surface of the sample tube. In actual use, holding the pull ring 2022 moves the push plate 2021 upwards. Since the push plate 2021 does not rotate, the multiple twisted rods 2027 that cooperate with it will rotate. This rotation of the twisted rods 2027 causes the base plate 2025, support rod 2028, and cleaning layer 2029 to rotate. The rotation of the cleaning layer 2029 rubs against the outer surface of the sample tube and the inner wall of the sample perforation 205, cleaning away any spilled liquid and adhering dust and other contaminants. Multiple sample perforations 205 can be cleaned simultaneously without affecting sample tube measurement and placement, increasing the convenience and stability of the instrument. It is also expected to facilitate simultaneous cleaning of the sample placement plate 201, saving time and effort.

[0029] Multiple limiting components 204 are provided between the push plate 2021 and the inner wall of the rectangular groove below. These limiting components 204 prevent the push plate 2021 from moving up and down while also preventing it from deflecting. The non-rotating push plate 2021 facilitates rotation with the twisted rod 2027 and provides suspension support, ensuring stable installation of the push plate 2021 below the pull-out sample holder 102. The limiting components 204 include a limiting plate 2041 fixed to the upper surface of the push plate 2021, with a rectangular sliding hole 2042 on its surface. A limiting slider 2043, T-shaped, is provided on the inner wall of the rectangular groove, slidingly engaging with the rectangular sliding hole 2042, allowing the push plate 2021 to move only up and down. In use, holding the pull ring 2022 moves the push plate 2021 upward, which in turn moves the limiting plate 2041 upward along the limiting slider 2043. The limiting slider 2043 fits against the inner wall of the rectangular sliding hole 2042, stably limiting the push plate 2021 and allowing it to move up and down along the limiting slider 2043, facilitating the engagement of the push plate 2021 with the twist rod 2027. Two pull rings 2022 are provided on the lower surface of the push plate 2021; these pull rings do not affect the pulling of the sample holder 102. The cleaning layer 2029 is a hollow cylindrical structure with openings on both the upper and lower surfaces. The cleaning layer 2029 can be made of fine cotton, thus preventing wear on the inside of the measuring instrument. The outer circumferential surface of the cleaning layer 2029 is attached to the inner wall of the sample perforation 205, while the inner circumferential surface of the cleaning layer 2029 is attached to the outer surface of the sample tube. As the cleaning layer 2029 rotates, the inner wall of the sample perforation 205 and the outer surface of the sample tube can be cleaned simultaneously.

[0030] The sample placement plate 201 has a stabilizing member 203 on its upper surface for further securing the sample tube. This stabilizing member 203 not only secures the placed sample tube but also accommodates sample tubes of different diameters within a certain range. Furthermore, it shields the upper surface of the sample placement plate 201, absorbing any liquid flowing from the sample tube and reducing the difficulty of cleaning the plate. The stabilizing member 203 includes a pad 2031 horizontally mounted on the upper surface of the sample placement plate 201. The pad 2031 has circular holes for the sample tube to pass through, and four metal springs 2034 are arranged around the outer circumference of each hole. A spherical clamping block 2035 is positioned at the upper end of each metal spring 2034. The metal springs 2034 provide clamping force to the spherical clamping block 2035 for the sample tube. The upper ends of the four metal springs 2034 are inclined inwards, minimizing the clamping space between the four spherical clamping blocks 2035. The spherical clamping block 2035 can be a rubber block, which facilitates the stable clamping of the sample tube. The side of the pad 2031 is provided with an inner arc-shaped strip 2033, and the side of the sample placement plate 201 is provided with an outer arc-shaped clamping plate 2032 that engages with the inner arc-shaped strip 2033. The outer arc-shaped clamping plate 2032 has a certain elasticity and elastic recovery potential energy. The outer arc-shaped clamping plate 2032 and the inner arc-shaped strip 2033 can be engaged and connected under the application of external force, which facilitates the disassembly and assembly of the entire stabilizing component 203.

[0031] The main body 100 of the measuring instrument has a measuring groove 101 inside. The pull-out sample holder 102 has a T-shaped structure, which facilitates the pull-out of the sample holder 102 into the measuring groove 101. A sealing ring 104, which is a rubber ring, is provided between the inner surface of the pull-out sample holder 102 and the main body 100 of the measuring instrument. This sealing ring provides a seal for the pull-out sample holder 102, increasing the safety of the sample tube measurement. The outer surface of the pull-out sample holder 102 has a pull-out groove 103, which facilitates pulling the pull-out sample holder 102. Preferably, a data display screen is provided on the upper surface of the main body 100 of the measuring instrument. The upper and lower surfaces of the synchronous cleaning mechanism 200 do not extend beyond the inner wall of the measuring groove 101, so as not to affect the pull-out of the sample holder 102. In use, the pad 2031 can be placed on the upper surface of the sample placement plate 201, aligning the round holes and sample perforations 205 on both surfaces. Applying external force slightly deforms the outer arc-shaped clamping plate 2032 outwards. When the inner arc-shaped strip 2033 is inside the outer arc-shaped clamping plate 2032, the outer arc-shaped clamping plate 2032 regains its elasticity, allowing the inner arc-shaped strip 2033 to engage with the outer arc-shaped clamping plate 2032. The sample tube is placed downwards from above the pad 2031 into the sample perforation 205, with the lower end of the sample tube extending into the four spherical clamping blocks 2035. The metal spring 2034 is slightly deformed outwards, generating an inward restoring force. The sample tube, extending downwards into the sample perforation 205, is stably clamped by the four spherical clamping blocks 2035, preventing deviation and wobbling, thus increasing the stability and safety of sample tube detection.

[0032] In use, the sample placement plate 201 is placed on the pull-out sample rack 102, and the placed sample tube is supported and stabilized by the stabilizing component 203, which increases the safety and stability of the sample tube measurement. At the same time, the limiting component 204 provides a limiting support for the movement of the push plate 2021. The push plate 2021 will drive the cleaning component 202 to work. The rotating cleaning layer 2029 cleans the inner surface of the sample perforation 205 and the outer surface of the sample tube at the same time, which improves the convenience of cleaning the sample placement plate 201, saves time and effort, and reduces the difficulty of cleaning.
