Description

Technical Field

[0001] This invention relates to the field of in vitro diagnostic instruments, and more particularly to a specific protein analyzer. Background Technology

[0002] In the field of in vitro diagnostics, the commonly used method for detecting the concentration of specific proteins is immunoturbidimetry. Its basic principle is that after the reagent and sample are mixed and reacted, the turbidity changes, and the concentration of the specific protein in the sample can be obtained by optically detecting the change in turbidity. The detection process requires adding the reagent and sample to the reaction apparatus and mixing thoroughly before using an optical detection module to acquire data.

[0003] Currently, there are semi-automatic and fully automatic specific protein analyzers. However, both semi-automatic and fully automatic specific protein analyzers require manual shaking of the sample tubes beforehand. The purpose of this process is to shake the coagulated or uneven sample before adding the reagents and sample to the reaction device for mixing. Manually shaking the sample tubes is inefficient and has high labor costs. Summary of the Invention

Two strip-shaped grooves are provided on the test tube clamps 9 for the mixing rod 13 and the synchronizing rod 14 to pass through, respectively. One end of the synchronizing rod 14 is fixedly connected to one of the test tube clamps 9, and the other end of the synchronizing rod 14 passes through the other test tube clamp 9. When a test tube needs to be sampled, the sample injection mechanism delivers it to the area below the test tube clamp 9. The closing module 16 drives the two test tube clamps 9 to open, and the longitudinal linear motion module 4 drives the lifting plate 7 to fall along the transmission guide rail 6, so that the test tube clamp 9 reaches the sampling position. Then, the closing module 16 drives the test tube clamp 9 to hold the sampling test tube firmly. The longitudinal linear motion module 4 drives the lifting plate 7 to rise along the transmission guide rail 6. When it rises to the point where the stainless steel bearing 11 enters the shaking groove 17 in the guide block 15, the test tube clamp 9 is driven to tilt to the right. The longitudinal linear motion module 4 lowers the lifting plate 7 along the transmission guide rail 6, and the guide wheel leaves the guide block 15. The above steps are repeated, and the sampling test tube clamped by the test tube clamp 9 is shaken. When the stainless steel bearing 11 moves back and forth in the shaking groove 17, the driven paddle 10 and the rotating plate 12 will swing back and forth. The rotating plate 12 drives the two test tube clamps 9 to swing simultaneously through the mixing rod 13 and the synchronizing rod 14, thereby achieving the shaking of the sample. In this way, agglomerated or uneven samples can be shaken evenly without manual processing, which improves work efficiency and reduces labor costs.

[0035] In this configuration, multiple first synchronous pulleys 18 are rotatably connected to the support frame 3 and are located on the sides of the support frame 3.

The first clamping plate 23 drives the synchronous belt 22 to move, and the synchronous belt 22 drives the second clamping plate 24 to move. The first clamping plate 23 and the second clamping plate 24 simultaneously drive the two test tube clamps 9 to move. Thus, by controlling the first lead screw motor 25, the two test tube clamps 9 can be controlled to move closer or further apart to clamp and release the test tubes.

The electric linear module 27 is existing technology and can adopt the existing synchronous belt 22 linear module or the structure of the longitudinal linear motion module 4 of this application. After the sample test tubes are shaken evenly, the electric linear module 27 moves the transfer chamber 28 below the test tube clamp 9. The lifting motor 20 rotates, driving the transmission belt 19 to lower the lifting plate 7 along the transmission guide rail 6, placing the sampling test tubes into the test tube position of the transfer chamber 28. The first lead screw motor... The motor 25 rotates, causing the test tube clamp 9 to open and release the sampling test tube; then the lifting motor 20 rotates, driving the transmission belt 19 to raise the lifting plate 7 along the transmission guide rail 6, causing the test tube clamp 9 to detach from the sampling test tube; the transfer chamber 28 moves the sampling test tube into the sampling position for sampling; after sampling, the transfer chamber 28 returns the sampling test tube to below the test tube clamp 9, the lifting motor 20 rotates, driving the transmission belt 19 to lower the lifting plate 7 along the transmission guide rail 6, causing the test tube clamp 9 to fit onto the sampling test tube, and the clamping screw motor 25 rotates, causing the test tube clamp 9 to clamp tightly. Then, the lifting motor 20 rotates, causing the lifting plate 7 to rise along the transmission guide rail 6, and the test tube clamp 9 carries the sampling test tube away from the transfer chamber 28, and the transfer chamber 28 returns to the sampling position; finally, the lifting motor 20 rotates, driving the transmission belt 19 to lower the lifting plate 7 along the transmission guide rail 6, and put the sampling test tube back into the test tube rack.

The horizontal linear motion module 30 is used to drive the transfer chamber 28 to move horizontally. The horizontal linear motion module 30 is existing technology and can adopt either the existing synchronous belt 22 linear module or the structure of the longitudinal linear motion module 4 of this application. The second lead screw motor 32 is a through-shaft lead screw stepper motor with an external nut, and the slider 33 is fixed to the external nut of the second lead screw motor 32. The transfer chamber 28 brings the sampling tube to the sampling position. The horizontal linear motion module 30 sends the sampling needle 37 above the sampling position. The positioning optocoupler 38 determines whether it is in the positioning slot 64 position. The second lead screw motor 32 rotates, and the sampling needle 37 is lowered into the sampling tube via the lead screw. The liquid level sensing device 39 determines whether there is a sample in the sampling tube. After the sampling needle 37 completes sampling, the second lead screw motor 32 rotates, and the sampling needle 37 is raised via the lead screw and the slider 33.

The automatic negative pressure liquid circuit system and the control unit are mature technologies in existing specific protein analyzers and are not within the scope of protection of this application. Their working principles will not be described in detail here.

[0041] When using this invention, the automatic sample feeding mechanism transfers the first test tube to the sample mixing mechanism 2's test tube clamping position. When the sample test tube reaches the sample mixing mechanism 2's test tube clamping position, the sample mixing mechanism 2 clamps the test tube and mixes it. After mixing, the test tube is placed in the transfer chamber 28. The electric linear module 27 drives the transfer chamber 28 to move the test tube to the sampling position. The sampling mechanism 29 receives the sampling command, collects the reagent 1 corresponding to the test mode from the sampling hole 55 of the reagent tray 46, adds it to the reaction cup 58 as the base liquid, then collects the sample from the sampling position and adds it to the reaction cup 58, and mixes it using the sampling needle 37. Finally, the sample is collected from the reagent tray... 46. ​​Reagent 2 corresponding to the test mode is added to reaction cup 58 and mixed well, and the sample reagent mixture begins to react; the multi-source optical detection mechanism 56 receives the detection command, turns on the corresponding light source according to the test mode in the command, and collects the light signal in real time; the sample shaking mechanism 2 puts the sample tube back into the test tube rack, and the sample injection mechanism pushes the next sample tube to the test tube clamping position of the sample shaking mechanism 2, and repeats the above steps. When the test in a certain reaction cup 58 is completed, the light source is turned off, the collected data is transmitted to the instrument control unit (INC) for processing and output of the test results, and the automatic negative pressure liquid circuit system rinses the reaction cup 58.

[0042] This invention discloses a specific protein analyzer that, through a sample mixing mechanism 2, can mix agglomerated or uneven samples without manual processing, thus improving work efficiency and reducing labor costs. When samples are added to reaction cups 58, multiple reaction cups 58 are available, allowing for simultaneous testing of multiple samples or multiple tests on the same sample. The reagent tray 46 can automatically transfer reagents for each test item to the reagent sampling position, enabling automatic selection of multiple reagents. The multi-light source optical detection mechanism 56 has multiple wavelengths of light sources, allowing the use of appropriate light sources according to the test requirements. The angle receiver 62 and angle receiver 63 in the multi-light source optical detection mechanism 56 are respectively a scattering receiver and a transmission receiver, allowing for the simultaneous use of scattering turbidimetry and transmission turbidimetry in the testing methodology. This invention solves the problems of existing specific protein analyzers that can only test one sample at a time, can only test one test per sample simultaneously, and require manual sample mixing and addition.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
