REACTION CUP CONVEYOR AND IMMUNOLOGICAL DETECTION DEVICE

Description

TECHNICAL FIELD

[0001] The present invention relates to the field of biological detection and diagnosis, and in particular, to a reaction cup conveying device and an immunological detection apparatus.BACKGROUND

[0002] With the development of modern science, an immunodiagnostic technology has gradually become a key means of modern clinical testing and scientific research. The immunodiagnostic technology is an important diagnostic tool for diseases such as tumors, diabetes, and abnormal secretion of gonads. Compared with conventional detection means, which have disadvantages of complex manual operations, long reaction time, and environmental pollution, the immunodiagnostic technology such as a chemiluminescence immunoassay technology has advantages of short reaction time, simple operations, and high diagnostic efficiency and has been widely used in modern medicine and scientific research fields.

[0003] Currently, the chemiluminescent immunoassay system mainly includes: a reaction cup storage and transfer system, a sample loading system, a reagent loading system, a sample adding system, an incubation system, a centrifugal cleaning system, and a luminous reading system. The incubation system is associated with the sample adding system, the centrifugal cleaning system, and the luminous reading system. The incubation system is required to continuously convey a reaction cup to a designated position. In this one-to-many situation, a lot of waiting time is wasted, and efficiency of instrument testing is relatively low. Due to a large number of test items and a large amount of sample testing in large hospitals, the efficiency of instrument testing is far from meeting a requirement.

[0004] CN 111 521 833 A discloses a chemiluminescence immunoassay reaction disc with multiple reaction modes and an analyzer capable of meeting multi-mode detection requirements.SUMMARY

[0005] Accordingly, it is necessary to provide a reaction cup conveying device and an immunological detection apparatus that can implement the accurate conveying of a certain number of reaction cups, and solve the problems of the poor positioning accuracy and complex structure of the conveying of reaction cups by means of an outer annular plate body in an existing mechanism.

[0006] Aspects of the invention are set out in the appended claims.

[0007] The reaction cup conveying device disclosed herein has the following beneficial effects.

[0008] (1) The outer circular conveying plate body of the reaction cup conveying device uses a structure of a gear made of engineering plastics and sleeved with a metal outer plate reinforcing member, which is light and simple in structure and has good gear strength and rigidity, stable power transmission, and durable and accurate positioning accuracy. In use, stability and accuracy of the reaction cup conveying device are guaranteed.

[0009] (2) In the above reaction cup conveying device, through the arrangement of the fit rolling member such as the V-shaped roller, the outer edge of the inner circular conveying plate body can be lubricated, so that when rotating at a high speed, the outer circular conveying plate body may not produce high friction noise, rub off powder, or even cause damages to and failure of the roller or the flange with the inner circular conveying plate body. Further, the V-shaped roller may use a self-lubricating material and an oil storage tank structure to prolong the overall service life of the device and reduce the cost of manual maintenance.

[0010] (3) The fit rolling member such as the V-shaped roller is in contact with the inner circular conveying plate body by abutment and tangency, i.e., point-to-point contact, which can minimize the contact area between the V-shaped roller and the inner circular conveying plate body, thereby reducing losses of mutual friction and also improving stability of the conveying of the outer circular conveying plate body and positioning accuracy of the conveying. Point-to-point contact friction realizes relative motion, which makes the overall operation of the device more stable, so that the positioning accuracy is more accurate and adaptability is wider.

[0011] (4) In the reaction cup conveying device, through the positioning of the V-shaped roller, the outer circular conveying plate body is suspended on the inner circular conveying plate body, the outer circular conveying plate body and the inner circular conveying plate body can convey the reaction cups independently, the outer circular conveying plate body and the inner circular conveying plate body can respectively meet system schemes under different time sequences, the outer circular conveying plate body and the inner circular conveying plate body can operate independently of each other, and positioning parameters can be associated with each other, so application scenarios are more extensive. In addition, the outer circular conveying plate body and the inner circular conveying plate body are positioned through the V-shaped roller, so that the whole device has a simple structure.BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Referring to FIG. 1, an embodiment of the present invention provides a reaction cup conveying device 10.

[0022] The reaction cup conveying device 10 includes an inner circular conveying plate body 100, an outer circular conveying plate body 200, reaction cup loading assemblies 300, and a driving mechanism 400.

[0023] The outer circular conveying plate body 200 is sleeved on the inner circular conveying plate body 100 and can rotate relative to the inner circular conveying plate body 100. The plurality of reaction cup loading assemblies 300 are arranged on a plate surface of the outer circular conveying plate body 200 at intervals. The reaction cup loading assembly 300 is provided with an embedding groove 310 for embedding a reaction cup.

[0024] The driving mechanism 400 is connected to the outer circular conveying disc body 200 and is configured to drive the outer circular conveying disc body 200 to rotate. The driving mechanism 400 may be a driving motor.

[0025] In some embodiments, the reaction cup conveying device 10 further includes a conveying transmission mechanism 500. The conveying transmission mechanism 500 includes a transmission driving gear 510 and a transmission shaft 520. Gear teeth are provided on a periphery of the outer circular conveying plate body 200.

The transmission driving gear 510 is engaged with the outer circular conveying plate body 200. The driving mechanism 400 drives the transmission driving gear 510 to rotate, so as to drive the outer circular conveying plate body 200 to rotate, thus conveying of reaction cups by the outer circular conveying plate body 200.

[0026] In some embodiments, a transmission ratio of the transmission driving gear 510 to the outer circular conveying plate body 200 ranges from 1:4 to 1:20. For example, in a specific embodiment, the transmission ratio of the transmission driving gear 510 to the outer circular conveying plate body 200 is 1:4.

It is not difficult to understand that in other embodiments, the transmission ratio of the transmission driving gear 510 to the outer circular conveying plate body 200 may alternatively be 1:5, 1:6, 1:7, 1:8, 1:9, 1:11, 1:12, 1:12, 1:14, 1:15, 1:16, 1:17, 1:18, 1:19, or other non-integer ratios.

[0027] In some embodiments, the plurality of reaction cup loading assemblies 300 are distributed at intervals on the plate surface of the outer circular conveying plate body 200. The number of the plurality of reaction cup loading assemblies 300 on the plate surface of the outer circular conveying plate body 200 may be two, three, four, five, ..., ten, ..., fifteen, or like. Preferably, the plurality of reaction cup loading assemblies 300 on the plate surface of the outer circular conveying plate body 200 are evenly distributed.

[0028] In some embodiments, the outer circular conveying plate body 200 is a plastic plate body. A material of the outer circular conveying plate body 200 may be engineering plastic. The above reaction cup conveying device 10 realizes power transmission through the plastic outer circular conveying plate body 200 made of engineering plastic, and the engineering plastic has a low cost, which can reduce the overall cost of the reaction cup conveying device 10. It should be understood that in other embodiments, the above reaction cup conveying device 10 may alternatively use a ring metal gear to realize power transmission. Compared with the ring metal gear, the plastic outer circular conveying plate body 200 made of engineering plastic has a low cost.

[0029] In some embodiments, the reaction cup conveying device 10 further includes an outer plate reinforcing member 600. The outer plate reinforcing member 600 has a ring structure, and the outer plate reinforcing member 600 is connected to the outer circular conveying plate body 200. In order to enhance strength of the reaction cup conveying device 10, the reaction cup conveying device 10 is provided with the outer plate reinforcing member 600, so as to enhance structural strength of the outer circular conveying plate body 200. Through fitting between a metal sheet and the outer circular conveying plate body 200 made of engineering plastic, the structural strength of the outer circular conveying plate body 200 can be greatly improved, and stability of the conveying of the reaction cups is improved.

[0030] In some embodiments, the outer plate reinforcing member 600 is a metal sheet. A thickness of the outer plate reinforcing member 600 ranges from 0.1 mm to 10 mm. The outer circular conveying plate body 200 of the reaction cup conveying device 10 uses a structure of a gear made of engineering plastic and sleeved with a metal outer plate reinforcing member 600, which is light and simple in structure and has good gear strength and rigidity, stable power transmission, and durable and accurate positioning accuracy. In use, stability and accuracy of the reaction cup conveying device 10 are guaranteed.

[0031] For example, in an embodiment, the thickness of the outer plate reinforcing member 600 is 0.1 mm. In another embodiment, the thickness of the outer plate reinforcing member 600 is 5mm. In another embodiment, the thickness of the outer plate reinforcing member 600 is 10 mm. It should be understood that in other embodiments, the thickness of the outer plate reinforcing member 600 is 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 2 mm, 3 mm, 4 mm, 6 mm, 7 mm, 8 mm, 9 mm, or other values.

[0032] The reaction cup conveying device 10 further includes a sliding fit mechanism 700. The sliding fit mechanism 700 includes a fit rolling member 710, which is rotatably connected to the outer circular conveying plate body 200. The fit rolling member 710 abuts and rolls against an outer peripheral surface of the inner circular conveying plate body 100. In the reaction cup conveying device 10, through the arrangement of the fit rolling member 710, which is a V-shaped roller, an outer edge of the inner circular conveying plate body 100 can be lubricated, so that when rotating at a high speed, the outer circular conveying plate body 200 will not produce high friction noise, rub off powder, or even cause damages to and failure of the roller or the flange with the inner circular conveying plate body 100.

[0033] In some implementations not falling under the scope of the appended claims, the fit rolling member 710 may be a roller, a ball, a rolling ball, or the like.

In another embodiment, the fit rolling member 710 may be a rolling ball.

[0034] The sliding fit mechanism 700 further includes a rolling shaft 720. The fit rolling member 710 is a V-shaped roller. The V-shaped roller has a V-shaped groove on a rolling surface of the roller. In this way, a contact area between the fit rolling member 710 and the inner circular conveying plate body 100 can be reduced. The fit rolling member 710 is rotatably connected to the outer circular conveying plate body 200 through the rolling shaft 720. The V-shaped roller of the reaction cup conveying device 10 can lubricate a track groove through a structure of an oil storage tank and self-lubricating engineering plastics. It should be understood that in other embodiments, the V-shaped roller may alternatively be lubricated by regular maintenance. For example, lubricating oil is regularly applied to the V-shaped roller.

[0035] In some embodiments, an inner side of the fit rolling member 710 abuts against the outer peripheral surface of the inner circular conveying plate body 100, and an outer side of the fit rolling member 710 is coplanar with an edge of the outer circular conveying plate body 200.

[0036] In some embodiments, a plurality of sliding fit mechanisms 700 are provided. Through the arrangement of the plurality of sliding fit mechanisms 700, interaction between the inner circular conveying plate body 100 and the outer circular conveying plate body 200 can be achieved from a plurality of angles.

[0037] In some embodiments, the plurality of sliding fit mechanisms 700 are distributed at intervals on the outer circular conveying plate body 200.

[0038] In some embodiments, the plurality of sliding fit mechanisms 700 are distributed at equal intervals, that is, evenly distributed, on the outer circular conveying plate body 200. The sliding fit mechanisms 700 distributed at equal intervals can evenly exert forces on the inner circular conveying plate body 100, and realize contact and interaction between the inner circular conveying plate body 100 and the outer circular conveying plate body 200 in a plurality of directions.

[0039] In some embodiments, the sliding fit mechanism 700 further includes a bottom plate 730 and a fastener 740. The bottom plate 730 is connected to the outer plate reinforcing member 600 through the fastener 740. The fit rolling member 710 is connected to the bottom plate 730 through the rolling shaft 720. In the above reaction cup conveying device 10, through the arrangement of the bottom plate 730 and the fastener 740, a detachable connection between the fit rolling member 710 and the outer plate reinforcing member 600 can be achieved. By arranging detachable connection of the fit rolling member 710, operations such as disassembly, maintenance, and replacement thereof can be facilitated, and it is convenient for an operator to operate, thereby saving time and efforts.

[0040] This embodiment further provides an immunological detection apparatus.
