Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a photometric disc with a warming function. Background Art

[0002] Chemiluminescent labeled immunoassay, also known as chemiluminescent immunoassay (CLIA), is an immunoassay method that directly labels antigens or antibodies with chemiluminescent agents. A chemiluminescent immunoassay analyzer consists of two parts, namely an immune reaction system and a chemiluminescent analysis system. The chemiluminescent analysis system uses chemiluminescent substances catalyzed by a catalyst and oxidized by an oxidant to form an excited intermediate. When this excited intermediate returns to the stable ground state, photons (hν) are emitted simultaneously. A luminescence signal measuring instrument is used to measure the quantum yield of light. The immune reaction system directly labels the luminescent substance (which generates an excited intermediate under the excitation of a reactant) on the antigen (chemiluminescent immunoassay) or antibody (immunochemiluminescent assay), or an enzyme acts on the luminescent substrate.

[0003] Currently, chemiluminescent immunoassay generally uses a fully automatic immunoassay analyzer to achieve automatic detection. A photometric disc is used in the fully automatic immunoassay analyzer. However, the existing photometric disc only has a photometric function and cannot keep the substrate warm and mixed during the waiting period for testing. Moreover, the existing photometric disc may have the problem of stray light interference during testing. Summary of the Invention

[0004] Aiming at the problems raised in the above background art, the purpose of the utility model is to provide a photometric disc with a warming function.

[0005] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A photometric disc with a warming function includes a warming chamber, a sealing mechanism connected above the warming chamber, a photometric mechanism connected to the outer circumference of the warming chamber, a labyrinth-shaped turntable rotatably connected to the inner cavity of the warming chamber, a substrate injection mechanism that can move up and down and cooperates with the sealing mechanism and whose output end extends into the warming chamber, and a transmission mechanism that penetrates into the warming chamber from below and is power-connected to the labyrinth-shaped turntable;

[0007] The labyrinth-shaped turntable forms a plurality of annularly distributed warming workstations that penetrate to the bottom through downward depressions, and the labyrinth-shaped turntable is provided with detection channels on its circumferential surface that are connected to the warming workstations;

[0008] The bottom of the warming chamber is provided with a through hole corresponding to the position of the warming workstation and is connected with a mixing mechanism that can move up and down at the through hole. The warming chamber is provided with a heating pad and heat insulation cotton.

[0009] Further defined, the substrate injection mechanism includes two injectors, a bracket for mounting the injectors, and a lead screw threadedly connected to the bracket. The rotational freedom of the bracket is restricted. With such a structural design, the power is transmitted to the bracket with restricted rotational freedom through the rotation of the lead screw, so that the bracket moves up and down with different rotation directions. The movement of the bracket can drive the injectors to move up and down, determining whether the injectors enter the incubation chamber and the depth of insertion.

[0010] Further defined, the sealing mechanism includes a sealing cover adapted to the incubation chamber and two light-shielding sleeves connected above the sealing cover. The sealing cover is provided with a through cavity at the position corresponding to the light-shielding sleeves. The injectors extend into the light-shielding sleeves and enter the incubation chamber through the through cavity. The vertically downward output ends of the injectors face the incubation station. With such a structural design, the incubation chamber is sealed and shielded from light by the sealing cover, and the injectors are shielded from light by the light-shielding sleeves.

[0011] Advantages of the present utility model:

[0012] 1. During the photometric queuing process, incubation is increased, thereby improving the biological reaction efficiency;

[0013] 2. It has the functions of substrate injection and mixing, making the entire photometric disc have good expandability;

[0014] 3. The photometric disc forms a maze structure through the detection channels, effectively dealing with external stray light and meeting the requirements of a darkroom. Description of the Drawings

[0030] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0031] As Figures 1-6 shown, a photometric disc with a warming function according to the present utility model includes an incubation chamber 2, a sealing mechanism 3 connected above the incubation chamber 2, a photometric mechanism 1 connected to the outer circumference of the incubation chamber, a labyrinth turntable 5 rotatably connected to the inner cavity of the incubation chamber 2, a substrate injection mechanism 4 that cooperates with the sealing mechanism 3 and has an output end extending into the incubation chamber 2 and capable of moving up and down, and a transmission mechanism 6 that penetrates from below the incubation chamber 2 and is power-connected to the labyrinth turntable 5;

[0032] The labyrinth turntable 5 forms a plurality of annularly distributed incubation stations 51 that penetrate to the bottom through downward depressions, and the labyrinth turntable 5 is provided with detection channels 52 on the circumferential surface that communicate with the incubation stations 51;

[0033] A through hole 21 corresponding to the position of the incubation station 51 is provided at the bottom of the incubation chamber 2, and a mixing mechanism 7 that can move up and down is connected at the through hole 21. The incubation chamber 2 is provided with a heating pad and heat-insulating cotton.

[0034] In the implementation of this case, a plurality of independent incubation stations 51 are provided on the labyrinth turntable 5. The incubation chamber 2 is provided with a heating pad and heat-insulating cotton. The test tubes are placed in the incubation stations 51, and the substrate is injected through the substrate injection mechanism 4. After the injection is completed, the substrate injection mechanism 4 withdraws upward to avoid interfering with the rotation of the labyrinth turntable 5;

[0035] During the photometric queuing process, the internal heat of the incubation chamber 2 is maintained by the heating pad and the heat preservation cotton, thereby improving the biological reaction efficiency. The mixing mechanism 7 extends from the bottom of the incubation station 51, rotates the test tube and mixes the substrate. After the mixing is completed, it withdraws downward to avoid interfering with the rotation of the maze-shaped turntable 5;

[0036] Driven by the transmission mechanism 6, the maze-shaped turntable 5 rotates at a set speed, so that the test tubes in each incubation station 51 will pass through the photometric mechanism 1 to complete the measurement;

[0037] During the test, the detection channel 52 enters the incubation station 51 from the side of the circumference of the maze-shaped turntable 5 to form a maze, eliminating external stray light interference and meeting the requirements of a dark room.

[0038] Preferably, the substrate injection mechanism 4 includes two injectors 41, a bracket for installing the injectors 41, and a lead screw threadedly connected to the bracket. The rotational freedom of the bracket is restricted. With such a structural design, the power is transmitted to the bracket with restricted rotational freedom through the rotation of the lead screw, so that the bracket moves up and down with different rotation directions. The movement of the bracket can drive the injector 41 to move up and down, determining whether the injector 41 enters the incubation chamber 2 and the depth of insertion. In fact, other structural shapes of the substrate injection mechanism 4 can also be considered according to specific situations.

[0039] Preferably, the sealing mechanism 3 includes a sealing cover adapted to the incubation chamber 2 and two light-shielding sleeves 31 connected above the sealing cover. The sealing cover is provided with a through cavity at the position corresponding to the light-shielding sleeves 31. The injector 41 extends into the light-shielding sleeves 31 and enters the incubation chamber 2 through the through cavity. The vertically downward output end of the injector 41 faces the incubation station 51. With such a structural design, the incubation chamber 2 is sealed and shielded from light by the sealing cover, and the injector 41 is shielded from light by the light-shielding sleeves 31. In fact, other structural shapes of the sealing mechanism 3 can also be considered according to specific situations.

[0040] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
