Description

Technical Field

[0001] The invention relates to the technical field of chemical analysis equipment, in particular to a double-chamber 16-channel chemiluminescence instrument. Background Art

[0002] The dual-chamber 16-channel chemiluminescence instrument is a POCT chemiluminescence analyzer.

[0003] The detection principle adopted by the analyzer is CLEIA (chemiluminescent enzyme immunoassay). The reagents used for each test are stored in a special 15-well reagent strip sealed with aluminum foil. The detection principle of the fully automatic chemiluminescence analyzer is described through the most widely used sandwich reaction mode. The analyte in the sample is combined with the alkaline phosphatase-labeled antibody and the biotinylated antibody to form a sandwich structure. The excess streptavidin-coated magnetic particles form a complex with the biotinylated antibody. After washing, the luminescent substrate is catalytically cleaved by the enzyme in the complex to form an unstable excited intermediate. When the excited intermediate returns to the ground state, it emits photons. The light intensity of the reaction is detected by a photomultiplier tube, and the luminescence intensity is converted into the concentration of the analyte by the random software.

[0004] When using the dual-chamber 16-channel chemiluminescence instrument, the reagent detection tube needs to be inserted into the channel of the dual-chamber 16-channel chemiluminescence instrument. However, the channel size of the dual-chamber 16-channel chemiluminescence instrument is mostly fixed and cannot adapt to reagent detection tubes of different sizes. The scope of use is subject to certain restrictions. After the reagent detection tube is placed in the designated position, after the detection reagent and the object to be detected come into contact, the detection reagent and the object to be detected slowly react under the influence of time.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The height of the support base is adjusted by supporting the support base with a height adjustment ring to ensure that the distance between the top of the reagent test tube and the reagent strip is appropriate to prevent the test reagent dripping from the reagent strip from splashing out, and to ensure that the bottom of the reagent test tube can be supported by the support base to adapt to reagent test tubes of different sizes. The support base can also drive the reagent test tube to rotate, assisting the mixing of the test reagent and the object to be detected in the reagent test tube. While adapting to reagent test tubes of different sizes, it can also assist the mixing of the test reagent and the object to be detected in the reagent test tube. There is no need to equip test tubes of different sizes with special mixing equipment, saving operation time and preparation work. Uniform and effective liquid mixing helps to ensure the accuracy and repeatability of experimental results.

[0018] 2. By rotating the handle mounted on the hexagonal rotating part, the threaded rotating rod is driven to rotate. By rotating the threaded rotating rod, the threaded rotating rod is raised and lowered in the internal threaded sleeve. By frequently disassembling the rotating handle on the hexagonal rotating part, the rotation of the hexagonal rotating part in a small space is ensured. The position of the threaded rotating rod in the internal threaded sleeve is adjusted, and the length of the structure composed of the internal threaded sleeve and the threaded rotating rod is changed to adjust the height of the transverse connecting rod. The height of the vertical lifting rod and the height adjustment ring is changed by changing the height of the transverse connecting rod. When the structure composed of the vertical lifting rod and the height adjustment ring rises, pressure is applied to the first positioning seat, thereby applying pressure to the support seat, increasing the length of the telescopic rod, and the support seat supports the bottom of the reagent detection tube at a higher position to adapt to shorter reagents. The test tube, when the vertical lifting rod and the height adjustment ring structure descend, pressure is applied to the second positioning seat to reduce the length of the telescopic rod. The support seat supports the bottom of the reagent test tube at a lower position to adapt to the longer reagent test tube. At the same time, when the reagent test tube is placed between multiple elastic support rods, the side wall of the reagent test tube supports the elastic support rod. Reagent test tubes of different sizes have different supporting effects on the elastic support rod. The elastic support rod adapts to reagent test tubes of different sizes by deformation. At the same time, the limit rod can also remain vertical during the deformation of the elastic support rod to position and support the side of the reagent test tube. Researchers can choose test tubes of appropriate sizes according to the specific needs of the experiment without being restricted to specific specifications, thereby designing experiments more flexibly.

[0019] 3. After the reagent detection tube is placed between multiple elastic support rods, the bottom of the reagent detection tube is in contact with the support seat to ensure that the reagent detection tube is stably fixed on the support seat. The output shaft of the small motor provides power for the rotation of the installation sleeve, and the support seat above is driven to rotate through the installation sleeve. The rotation of the support seat drives the reagent detection tube to rotate slowly between multiple elastic support rods and limit rods, ensuring that the object to be detected and the detection reagent in the support seat are shaken, so that the object to be detected and the detection reagent are mixed faster and better, and the mixing effect of the object to be detected and the detection reagent is improved, thereby improving the detection efficiency and detection effect, ensuring that the various components in the liquid are fully contacted and mixed, so that the chemical reaction is carried out more evenly, and the consistency and accuracy of the reaction are improved. Good mixing can increase the collision chance between reactant molecules, thereby accelerating the reaction rate and saving experimental time. BRIEF DESCRIPTION OF THE DRAWINGS

The elastic support rod 5 is installed on the mounting rod 4 in an inclined state, and the elastic support rod 5 is an elastic support rod. The elastic support rod 5 can undergo a large deformation when subjected to force, and can return to its original state after the external force is removed. The elastic support rod 5 is made of rubber material to prevent the elastic support rod 5 from applying too much pressure to the reagent detection tube 12 and damaging the reagent detection tube 12. The existence of the elastic support rod 5 can ensure the stability of the reagent detection tube 12. The tube 12 is supported, and the deformation of the elastic support rod 5 adapts to reagent detection tubes 12 of different thicknesses, and assists the installation of reagent detection tubes 12 of different sizes. A small motor 6 is fixedly installed at the bottom of the inner wall of the test tube placement channel 2. The output shaft of the small motor 6 is coaxially arranged with the reagent detection tube 12, and the power is provided by the small motor 6 to assist the installation. A mounting sleeve 7 is fixedly installed on the output shaft of the small motor 6.

A telescopic rod 8 is coaxially fixedly installed on the top of the mounting sleeve 7. The telescopic rod 8 is a telescopic rod, which assists the installation. To assist the lifting and lowering of the first positioning seat 9, the top of the telescopic rod 8 is coaxially fixedly installed with the first positioning seat 9, and the top of the first positioning seat 9 is coaxially fixedly installed with a hexagonal plug 10. The first positioning seat 9 and the hexagonal plug 10 are an integrated structure. The first positioning seat 9 and the hexagonal plug 10 are connected to the support seat 11. The top of the hexagonal plug 10 is movably installed with a support seat 11, and a groove corresponding to the shape of the hexagonal plug 10 is provided at the bottom of the support seat 11. The connection between the hexagonal plug 10 and the support seat 11 is achieved through the groove provided at the bottom of the support seat 11, ensuring the installation stability of the support seat 11. A reagent detection tube 12 is arranged between the multiple elastic support rods 5, and the bottom of the reagent detection tube 12 fits with the top of the support seat 11.The top of the support seat 11 is provided with a groove corresponding to the shape of the bottom of the reagent detection tube 12. The bottom of the reagent detection tube 12 contacts the support seat 11, and the support seat 11 is a rubber part to prevent the reagent detection tube 12 from being damaged due to impact when placed. At the same time, the rubber can increase the relative friction between the support seat 11 and the reagent detection tube 12.

[0037] The support seat 11, the hexagonal plug 10, the first positioning seat 9, the telescopic rod 8 and the mounting sleeve 7 are coaxially arranged to ensure the stability of the support seat 11, the hexagonal plug 10, the first positioning seat 9, the telescopic rod 8 and the mounting sleeve 7 during rotation.

[0038] A fixing rope 13 is movably installed in the elastic support rod 5, and a groove corresponding to the fixing rope 13 is opened in the elastic support rod 5 to ensure that the fixing rope 13 is installed in the elastic support rod 5. The top of the fixing rope 13 passes through the threading groove 501 opened on the elastic support rod 5, and the end of the fixing rope 13 is knotted to ensure that the end of the fixing rope 13 can be stably installed in the elastic support rod 5. A limiting rod 14 is fixedly installed on the bottom end of the fixing rope 13. The limiting rod 14 fits the outer wall of the reagent detection tube 12. When adapting to reagent detection tubes 12 of different sizes, the elastic support rod 5 is deformed under pressure, and the limiting rod 14 always keeps sagging, so that the limiting rod 14 contacts the outer wall of the reagent detection tube 12, and the limiting rod 14 can also position the reagent detection tube 12 to prevent the position of the reagent detection tube 12 from shifting during the detection process.

[0039] A rectangular vertical groove 201 is provided on the front of the test tube placement channel 2, a vertical guide rod 15 is vertically fixedly installed in the rectangular vertical groove 201, a vertical lifting rod 16 is movably sleeved outside the vertical guide rod 15, and the vertical lifting rod 16 is located in the rectangular vertical groove 201, the vertical lifting rod 16 is lifted and lowered in the rectangular vertical groove 201, and when the vertical lifting rod 16 is lifted and lowered in the rectangular vertical groove 201, it is guided by the vertical guide rod 15 to ensure the stability of the vertical lifting rod 16 during the lifting process, and a height adjustment ring 17 is fixedly installed on the end of the vertical lifting rod 16, and the height adjustment ring 17 is movably sleeved on the extension rod 16. Outside the retractable rod 8, the height adjustment ring 17 is located below the first positioning seat 9, and the second positioning seat 18 is fixedly sleeved on the telescopic rod 8, and the second positioning seat 18 is arranged below the height adjustment ring 17. The height adjustment ring 17 is located between the first positioning seat 9 and the second positioning seat 18. When the height adjustment ring 17 moves upward, it applies an upward force to the first positioning seat 9, and when the height adjustment ring 17 moves downward, it applies a downward force to the second positioning seat 18, thereby ensuring the lifting and lowering of the support seat 11. At the same time, during the lifting and lowering process of the second positioning seat 18, the telescopic rod 8 can also be pulled, thereby changing the relative length of the telescopic rod 8.

[0040] A transverse connecting rod 19 is provided between the vertical lifting rods 16 for connection. The existence of the transverse connecting rod 19 connects multiple vertical lifting rods 16 to ensure the control and manipulation of the synchronous lifting of multiple vertical lifting rods 16. A threaded rotating rod 20 is rotatably connected at the center position of the transverse connecting rod 19. The external thread of the threaded rotating rod 20 is connected to an internal threaded sleeve 21, and the bottom of the internal threaded sleeve 21 is fixedly installed on the bottom of the inner wall of the detector body 1. A hexagonal rotating part 22 is fixedly installed on the outside of the threaded rotating rod 20. A rotating handle 23 is movably sleeved on the hexagonal rotating part 22, and the rotating handle 23 is installed on the hexagonal rotating part 22. The hexagonal rotating part 22 and the threaded rotating rod 20 can be rotated by rotating the handle 23 as needed, so that the threaded rotating rod 20 can be lifted and lowered in the internal threaded sleeve 21, thereby changing the height of the transverse connecting rod 19 and realizing the adjustment of the height of multiple vertical lifting rods 16.

[0041] The front bottom of the detector body 1 is provided with an opening and closing door mounting seat 24, and an opening and closing door 25 is rotatably connected to the opening and closing door mounting seat 24. The opening and closing door mounting seat 24 and the opening and closing door 25 are connected together near one side. The opening and closing door 25 is pulled outward to open the opening and closing door 25, and the test tube placement channel 2 in the detector body 1 is displayed. By applying a pull to the opening and closing door 25, the opening and closing door 25 rotates around the edging strip 29 as the center, and the magnetic strip 28 on the door handle 26 and the magnetic strip 28 on the magnetic strip mounting frame 27 are rotated. The magnetic force will not affect the opening of the opening and closing door 25. The opening and closing door 25 is movably engaged on the front side of the detector body 1. A door handle 26 is provided on the top of the opening and closing door 25. The door handle 26 assists in pulling the opening and closing door 25 to realize the opening and closing of the opening and closing door 25. A edging strip 29 is provided outside the connection position between the opening and closing door 25 and the opening and closing door mounting seat 24 to strengthen the connection position between the opening and closing door mounting seat 24 and the opening and closing door 25 to prevent the connection position between the opening and closing door mounting seat 24 and the opening and closing door 25 from being disconnected.

[0042] A magnetic stripe mounting frame 27 is provided on the front side of the detector body 1 at a position corresponding to the door handle 26. The position of the magnetic stripe mounting frame 27 corresponds to the position of the door handle 26, ensuring that the magnetic stripe 28 on the back of the door handle 26 can contact the magnetic stripe 28. A magnetic stripe 28 is fixedly installed on the magnetic stripe mounting frame 27, and a magnetic stripe 28 is also provided on the bottom of the door handle 26. The magnetic stripe 28 on the door handle 26 and the magnetic stripe 28 on the magnetic stripe mounting frame 27 are adsorbed together by magnetic force. The adsorption between the magnetic stripes 28 realizes the fixation of the opening and closing door 25 without affecting the opening and closing of the opening and closing door 25.

[0043] A driving mechanism 30 is fixedly installed on the back side of the vertical mounting plate 3, and an extrusion bar 31 is movably installed on the vertical mounting plate 3. An assembly frame 32 is provided on the other side of the vertical mounting plate 3. The extrusion bar 31 is movably installed in the assembly frame 32. A filling layer 33 is provided in the assembly frame 32, and a reagent strip 34 is fixedly installed in the filling layer 33. The extrusion bar 31 is extended and retracted by the driving mechanism 30. An electric push rod is provided in the driving mechanism 30 to assist the extension and retraction of the extrusion bar 31. At the same time, the extension and retraction of the extrusion bar 31 applies pressure to the reagent strip 34 to squeeze out the detection reagent in the reagent strip 34, so that the detection reagent in the reagent strip 34 drips into the reagent detection tube 12.

[0044] The reagent strip 34 is arranged directly above the reagent detection tube 12 to ensure that the detection reagent in the reagent strip 34 can fall into the reagent detection tube 12 , and the extrusion strip 31 penetrates the filling layer 33 and contacts the side wall of the reagent strip 34 .

[0045] Working principle:

[0046] Step 1: The user inserts his hand into the groove on the door handle 26, and pulls the door 25. The door 25 rotates around the edging strip 29. The magnetic force between the magnetic strip 28 on the door handle 26 and the magnetic strip 28 on the magnetic strip installation frame 27 will not affect the opening of the door 25. After the door 25 is opened, the reagent detection tube 12 is placed between the four elastic support rods 5 to achieve the installation and positioning of the reagent detection tube 12. Then the door 25 is closed, and the magnetic strip 28 on the door handle 26 and the magnetic strip 28 on the magnetic strip installation frame 27 are mutually attracted. , to achieve fixation after the opening and closing door 25 is closed, to ensure that the reagent detection tube 12 is in a sealed state in the detector body 1 for detection, and the extrusion bar 31 on the driving mechanism 30 moves to make the extrusion bar 31 contact with the reagent strip 34, and the extrusion bar 31 applies pressure to the reagent strip 34 to squeeze the reagent strip 34, and the detection reagent in the reagent strip 34 drips into the reagent detection tube 12, contacts with the object to be detected in the reagent detection tube 12, mixes with the object to be detected in the reagent detection tube 12, and reacts, and then is detected by the optical detection module in the detector body 1.

[0047] Step 2: By rotating the handle 23 mounted on the hexagonal rotating part 22, the threaded rotating rod 20 is driven to rotate. By rotating the threaded rotating rod 20, the threaded rotating rod 20 is lifted and lowered in the internal threaded sleeve 21. By frequently disassembling the rotating handle 23 on the hexagonal rotating part 22, the rotation of the hexagonal rotating part 22 in a small space is ensured. The position of the threaded rotating rod 20 in the internal threaded sleeve 21 is adjusted, and the length of the structure composed of the internal threaded sleeve 21 and the threaded rotating rod 20 is changed to adjust the height of the transverse connecting rod 19. The change in the height of the transverse connecting rod 19 changes the height of the vertical lifting rod 16 and the height adjustment ring 17. When the structure composed of the vertical lifting rod 16 and the height adjustment ring 17 rises, pressure is applied to the first positioning seat 9, thereby applying pressure to the support seat 11, increasing the length of the telescopic rod 8, and the support seat 11 supports the bottom of the reagent detection tube 12 at a higher position to adapt to the shorter reagent detection tube 12. At the same time, the vertical lifting rod 16 and the height adjustment ring 17 form a structure that applies pressure to the second positioning seat 18 when it descends, thereby reducing the length of the telescopic rod 8. The support seat 11 supports the bottom of the reagent detection tube 12 at a lower position to adapt to the longer reagent detection tube 12. At the same time, when the reagent detection tube 12 is placed between multiple elastic support rods 5, the side wall of the reagent detection tube 12 supports the elastic support rod 5. Reagent detection tubes 12 of different sizes have different supporting effects on the elastic support rod 5. The elastic support rod 5 adapts to reagent detection tubes of different sizes by deformation. At the same time, the limit rod 14 can also remain vertical during the deformation of the elastic support rod 5 to position and support the side of the reagent detection tube 12.

[0048] Step 3: After the reagent detection tube 12 is placed between the multiple elastic support rods 5, the bottom of the reagent detection tube 12 contacts the support seat 11 to ensure that the reagent detection tube 12 is stably fixed on the support seat 11, and the output shaft of the small motor 6 provides power for the rotation of the mounting sleeve 7, which drives the upper support seat 11 to rotate through the mounting sleeve 7. The rotation of the support seat 11 drives the reagent detection tube 12 to rotate slowly between the multiple elastic support rods 5 and the limit rods 14, ensuring that the object to be detected and the detection reagent in the support seat 11 are shaken, so that the object to be detected and the detection reagent are mixed faster and better, thereby improving the mixing effect of the object to be detected and the detection reagent, thereby improving the detection efficiency and detection effect.
