Description

Technical Field

[0001] The utility model relates to a chemiluminescence immunoassay analyzer, in particular to a multifunctional sample system. Background Art

[0002] Chemiluminescence immunoassay (CLIA) combines highly sensitive chemiluminescence detection technology with highly specific immune reactions. It is used for the detection and analysis of various antigens, haptens, antibodies, hormones, enzymes, fatty acids, vitamins, and drugs. It is the latest immunoassay technology developed after radioimmunoassay, enzyme immunoassay, fluorescence immunoassay, and time-resolved fluorescence immunoassay.

[0003] The entire sample testing process of a chemiluminescent immunoassay involves numerous steps, including pipetting, dilution, and storage. In high-throughput analyzers designed for large-scale analysis and testing, the sample rack, pipetting tips, and liquid consumable bottles (such as diluent bottles) are all designed as independent modules and arranged in different locations within the chemiluminescent immunoassay. However, for low-throughput analyzers used for small batches, continuing to use this layout would result in a large space requirement. Utility Model Content

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] like Figure 1 and 2 As shown, a multifunctional sample system comprises a base 1, a carrier 2 rotatably mounted on the base 1, and a driving assembly 3 capable of driving the carrier 2 to rotate, wherein Figure 4 It can be seen that the circumferential side of the carrier 2 is distributed with loading stations, and a universal connection structure 4 is provided on the loading station, which is used to detachably install the sample rack 5 or the TIP head rack 6. At least one set of positioning structures 7 is integrated on the loading station, and the positioning structures 7 can position and install the liquid consumable bottle a. Figure 3 As shown, in this embodiment, the driving assembly 3 uses a motor 31, which is installed on the lower side of the base 1. The output shaft 32 of the motor 31 passes through the base 1 upward and is fixedly sleeved on the bottom of the carrier 2.

[0027] Based on this structural design, the loading station is compatible with the sample rack 5, TIP head rack 6, and liquid consumable bottle a. Therefore, the sample rack 5, TIP head rack 6, and liquid consumable bottle a can be integrated and assembled around the circumference of the carrier 2. Motor 31 drives output shaft 32 to rotate, driving the carrier 2 to complete the sampling, pipetting, and dilution steps of the analyzer. This highly compact and versatile design is suitable for low-throughput analyzers.

[0028] For example Figure 1 and 4As shown, the carrier 2 comprises a columnar structure 21 and a support plate 22 extending radially outward from the lower portion of the columnar structure 21. In this embodiment, the columnar structure 21 is a circular cylinder, and the support plate 22 is a circular support plate. A circular array of loading stations is distributed within the space defined by the circumferential sides of the columnar structure 21 and the support plate 22. This design, with its circular structure, achieves the technical effect of high space utilization.

[0029] For further information, see Figure 4 The universal connection structure 4 includes a protrusion 41 formed on the side of the column structure 21, and a hanging hole 411 is provided on the upper end of the protrusion 41. Figure 2 It can be seen that the multifunctional sample system further includes a sample rack 5 and a TIP head rack 6. In this embodiment, the sample rack 5 and the TIP head rack 6 have the same external structure, both of which are constructed into an arc structure. Figure 6 As shown, the inner sides of both the sample rack 5 and the TIP head rack 6 are provided with forward-protruding hooks b (since the outer contours of the two racks are identical, only the sample rack 5 is shown). The hooks b are adapted to fit within the hook holes 411 and can be removably inserted into the hook holes 411. When the hooks b of the sample rack 5 are inserted into the hook holes 411, the outer contour of the sample rack 5 conforms to the outer edge of the support plate 22.

[0030] Re-attend Figure 3 and Figure 4 The support plate 22 is circumferentially provided with slightly outwardly protruding flanges 221. Each flange 221 is provided with an upwardly extending stopper 42. In this embodiment, two stoppers 42 are provided on each flange 221. When the sample rack 5 or TIP head rack 6 is installed on the loading station, the stoppers 42 prevent the rack from falling radially outward along the support plate 22, ensuring a more stable assembly of the rack on the carrier 2.

[0031] like Figure 4 and 5 As shown, the positioning structure 7 includes an arc groove 71 provided on the side of the column structure 21, and the arc groove 71 is opposite to the convex edge 221. The arc groove 71 and the convex edge 221 just form a circular groove, so that the liquid consumable bottle a can be placed smoothly (refer to Figure 2 ), and the two stoppers 42 on the convex edge 221 effectively prevent the liquid consumable bottle a from falling out. In this embodiment, two arcuate grooves 71 are provided on each loading station, one on each side of the protrusion 41 of the loading station. This design increases the number of loading positions for liquid consumable bottles a, making the multifunctional sample system more compact. The liquid consumable bottle a mentioned in this embodiment can be a diluent bottle or other type of bottle.

[0032] Please refer to Figure 3 and Figure 5The multifunctional sample system also includes a barcode scanner 9, which faces the side of the carrier 2. Each sample rack 5 has a barcode scanning notch 51 on the outside of each test tube well. As the carrier 2 rotates, the infrared light emitted by the barcode scanner 9 directly scans the sample tubes on the sample rack 5 to obtain sample information.

[0033] like Figure 4 As shown, a dilution station is provided between two adjacent loading stations. The dilution station includes a support frame 8 arranged on the upper part of the column structure 21 and extending outward. The support frame 8 is provided with a cup placement hole 81 for placing a reaction cup. Such a design can meet the needs of sample addition and dilution, making the system more functional.

[0034] Furthermore, Figure 4 As shown, the support frame 8 is symmetrically provided with two sets of cup placement holes 81. A recovery channel 82 is arranged between the two sets of cup placement holes 81. This recovery channel 82 extends vertically through the support body 2 and is used to recover the used TIP tip. This design facilitates the disposal of used TIP tips and has the technical advantages of reasonable structural design and strong practicality.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
