Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and more particularly, to a reagent tray assembly and a biochemical analyzer. Background Art

[0002] The reagent tray assembly is one of the component modules of a biochemical analyzer and is used to store reagents required for test analysis. Reagents need to be stored in a low-temperature environment. Therefore, the reagent tray assembly is provided with a refrigeration device, and the refrigeration device provides low-temperature air to the reagent bottle container storing the reagent to achieve low-temperature storage of the reagent.

[0003] In order to enable the analyzer to test more items simultaneously and meet the high-speed requirements of the analyzer, generally, a relatively large number of reagents are placed in the reagent tray assembly. Therefore, the reagent bottle tray in the reagent tray assembly is designed into two inner and outer circles. Specifically, the related reagent tray assembly includes a reagent chamber, an inner circle tray, and an outer circle tray. The reagent chamber includes a chamber body and a chamber cover, and the reagent is accommodated in the accommodation cavities of the inner circle tray and the outer circle tray. The side wall and the bottom of the chamber body are used to transfer the cooling medium to the inner circle tray and the outer circle tray, so as to achieve low-temperature storage of the reagent.

[0004] However, the circumferential inner wall of the outer circle tray will block the cooling medium transmitted by the side wall of the chamber body, resulting in the obstruction of the cooling medium on the side wall from being transmitted to the inner circle tray, causing uneven temperatures of the inner circle tray and the outer circle tray, and thus affecting the storage effect of the reagent. Summary of the Utility Model

The reagent tray assembly and the biochemical analyzer of the present disclosure can make the temperatures of the inner tray and the outer tray uniform and improve the preservation effect of the reagents.

[0042] According to one aspect of the present disclosure, there is provided a reagent tray assembly 1. As Figure 1 shown, the reagent tray assembly 1 includes a reagent storage 11, an inner tray 12, and an outer tray 13. The reagent storage 11 serves as the accommodation storage of the reagent tray assembly 1. On the one hand, it is used to protect the inner tray 12, the outer tray 13 inside and the reagents accommodated therein from being damaged externally. On the other hand, it is used to accommodate different reagents, thereby realizing the preservation of the reagents. The reagent storage 11 includes a storage body 111 and a storage lid, and the storage lid covers the storage body 111, and a cavity is formed by enclosing the storage body 111 and the storage lid, thereby realizing the preservation of different types of reagents.

[0043] Among them, the inner tray 12 is disposed within the reagent storage 11. As Figure 2As shown, the inner ring tray 12 includes an inner ring bottom plate 121 and a plurality of inner ring partition members 122. The plurality of inner ring partition members 122 are all connected to the inner ring bottom plate 121 and extend along the radial direction of the inner ring bottom plate 121. The plurality of inner ring partition members 122 divide a plurality of inner ring accommodation cavities in the inner ring tray 12 for accommodating the first external reagent; the outer ring tray 13 is disposed in the reagent storage 11. As Figure 3 shown, the outer ring tray 13 includes an outer ring bottom plate 131, an outer ring connecting member 132 and a plurality of outer ring partition members 133. The plurality of outer ring partition members 133 are all connected to the outer ring bottom plate 131 and extend along the radial direction of the outer ring bottom plate 131. The outer ring connecting member 132 is circumferentially connected to one side of the plurality of outer ring partition members 133 close to the center of the outer ring bottom plate 131. The plurality of outer ring partition members 133 divide a plurality of outer ring accommodation cavities in the outer ring tray 13 for accommodating the second external reagent.

[0044] Further, the outer ring connecting member 132 is provided with a plurality of first through holes 1321, and the plurality of first through holes 1321 are distributed circumferentially along the outer ring connecting member 132. As Figure 4 shown, a first cooling medium is provided on the side wall of the housing 111. The first cooling medium enters the outer ring accommodation cavity through the gap between the plurality of outer ring partition members 133, and enters the inner ring accommodation cavity through the gap between the plurality of first through holes 1321 and the plurality of inner ring partition members 122.

[0045] It should be noted that in order to enable the biochemical analyzer to test more items simultaneously and meet the high-speed requirements of the biochemical analyzer, a large number of reagents need to be placed in the reagent disk assembly 1. Since the reagent disk assembly 1 includes an inner ring tray 12 and an outer ring tray 13, the inner ring tray 12 and the outer ring tray 13 are respectively used to accommodate the first external reagent and the second external reagent, so that the storage and testing of multiple reagents can be realized.

[0046] Similarly, it should be noted that the housing 111 can transmit the first cooling medium to the outer ring tray 13 and the inner ring tray 12 through the side wall of the housing 111, or transmit the second cooling medium to the outer ring tray 13 and the inner ring tray 12 through the bottom of the housing 111.

[0047] Among them, during the process of transferring the first cooling medium from the side wall of the bin body 111 to the outer ring tray 13, the first cooling medium can enter the outer ring accommodation cavity through the gaps between multiple outer ring partition members 133, thereby realizing the cooling of the second external reagent. Since the outer ring connecting member 132 is provided with a plurality of first through holes 1321, and the plurality of first through holes 1321 are distributed along the circumferential direction of the outer ring connecting member 132, the first cooling medium in the outer ring accommodation cavity can be transferred to the inner ring tray 12 through the first through holes 1321, and then enter the inner ring accommodation cavity through the gaps between the inner ring partition members 122, thereby realizing the cooling of the first external reagent. Thus, it can ensure the uniform transfer of the first cooling medium in the inner ring tray 12 and the outer ring tray 13, ensure the uniform temperature in the inner ring tray 12 and the outer ring tray 13, improve the preservation effect of the first external reagent and the second external reagent, and meet the technical requirements of the product.

[0048] The following will detail each part of the reagent tray assembly 1 and the biochemical analyzer:

[0049] In an exemplary embodiment of the present disclosure, the inner ring tray 12 further includes an inner ring connecting member 123. As Figure 2 shown, the inner ring connecting member 123 is circumferentially connected to one side of a plurality of inner ring partition members 122 close to the center of the inner ring bottom plate 121, and the inner ring connecting member 123 is provided with a plurality of second through holes 1231, and the plurality of second through holes 1231 are distributed along the circumferential direction of the inner ring connecting member 123.

[0050] Specifically, during the process of transferring the first cooling medium from the side wall of the bin body 111 to the outer ring tray 13, the first cooling medium is sequentially transferred to the outer ring accommodation cavity and the inner ring accommodation cavity through the gaps between multiple outer ring partition members 133, the first through holes 1321, and the gaps between multiple inner ring partition members 122, and circulates between the outer ring accommodation cavity and the inner ring accommodation cavity. Since the inner ring tray 12 further includes an inner ring connecting member 123, the inner ring connecting member 123 is circumferentially connected to one side of a plurality of inner ring partition members 122 close to the center of the inner ring bottom plate 121, and the inner ring connecting member 123 is provided with a plurality of second through holes 1231, and the plurality of second through holes 1231 are distributed along the circumferential direction of the inner ring connecting member 123, the first cooling medium transferred to the inner ring accommodation cavity can realize the further transfer and circulation of the first cooling medium through the connection of the plurality of second through holes 1231, thereby further improving the circulation of the first cooling medium, making the transfer of the first cooling medium smoother, and further improving the preservation effect of the first external reagent and the second external reagent.

[0051] In an exemplary embodiment of the present disclosure, a plurality of third through holes 1311 are provided on the outer ring bottom plate 131, and the plurality of third through holes 1311 are circumferentially distributed on the outer ring bottom plate 131 between two adjacent outer ring partition members 133; a plurality of fourth through holes 1211 are provided on the inner ring bottom plate 121, and the plurality of fourth through holes 1211 are circumferentially distributed on the inner ring bottom plate 121 between two adjacent inner ring partition members 122. As Figure 2 and Figure 3 shown, a second cooling medium is provided at the bottom of the bin body 111, and the second cooling medium enters the outer ring accommodation cavity and the inner ring accommodation cavity through the third through holes 1311 and the fourth through holes 1211.

[0052] Specifically, since a second cooling medium is provided at the bottom of the bin body 111, a plurality of third through holes 1311 are provided on the outer ring bottom plate 131, and a plurality of fourth through holes 1211 are provided on the inner ring bottom plate 121, the second cooling medium can enter the outer ring accommodation cavity and the inner ring accommodation cavity through the third through holes 1311 and the fourth through holes 1211, so as to realize the transmission of the cooling medium for the outer ring accommodation cavity and the inner ring accommodation cavity, so that the outer ring accommodation cavity and the inner ring accommodation cavity can be affected not only by the first cooling medium in the radial direction, but also by the second cooling medium in the axial direction, so that the temperature in the outer ring accommodation cavity and the inner ring accommodation cavity can be made uniform, and the preservation effect of the first external reagent and the second external reagent can be improved.

[0053] In an exemplary embodiment of the present disclosure, the reagent tray assembly 1 further includes a power member, and the power member includes a first power member and a second power member. The first power member and the second power member are respectively connected to the inner ring bottom plate 121 and the outer ring bottom plate 131 for respectively driving the inner ring tray 12 and the outer ring tray 13 to rotate. Specifically, during the process of detecting the first external reagent and the second external reagent in the inner ring tray 12 and the outer ring tray 13, it is necessary to continuously rotate the inner ring tray 12 and the outer ring tray 13, so that the corresponding first external reagent and the second external reagent in the inner ring tray 12 and the outer ring tray 13 are sequentially rotated to the testing machine. Since the power member includes a first power member and a second power member, and the first power member and the second power member are respectively connected to the inner ring bottom plate 121 and the outer ring bottom plate 131 for respectively driving the inner ring tray 12 and the outer ring tray 13 to rotate, the inner ring tray 12 and the outer ring tray 13 can be made not to affect each other during the rotation process, so that the first external reagent and the second external reagent can respectively correspond to the machines to be detected, thereby improving the detection efficiency of the first external reagent and the second external reagent. At the same time, it is convenient for the operator to operate.

[0054] In an exemplary embodiment of the present disclosure, the outer ring tray 13 further includes a plurality of protrusions 134, and the protrusions 134 are fixedly arranged on the side of the outer ring partition member 133 close to the center of the outer ring bottom plate 131. As Figure 3As shown, in the process of placing the first external reagent in the inner ring accommodating cavity and the second external reagent in the outer ring accommodating cavity, on the one hand, due to the large number of outer ring partition members 133 and inner ring partition members 122, and on the other hand, due to the small distance between the outer ring partition members 133, outer ring connecting members 132 and inner ring partition members 122, during the placement of the first external reagent and the second external reagent, it is very easy to cause misalignment of the first external reagent and the second external reagent. By providing a protrusion 134 on the outer ring tray 13, and the protrusion 134 is fixedly arranged on the side of the outer ring partition member 133 close to the center of the outer ring bottom plate 131, it is possible to prevent misalignment between the first external reagent and the second external reagent, thereby improving the storage accuracy of the first external reagent and the second external reagent, and further improving the detection accuracy of the first external reagent and the second external reagent during the detection process of the first external reagent and the second external reagent.

[0055] In an exemplary embodiment of the present disclosure, along the projection direction of the outer ring bottom plate 131, the shape of the protrusion 134 is triangular. Specifically, in the process of placing the first external reagent and the second external reagent, since along the projection direction of the outer ring bottom plate 131, the shape of the protrusion 134 is triangular, on the one hand, the first external reagent and the second external reagent can be accurately placed in the corresponding areas through the triangular mark, which is convenient for the operator to observe and improves the storage accuracy of the first external reagent and the second external reagent. On the other hand, since the shape of the protrusion 134 is triangular, when the second external reagent is placed in the outer ring accommodating cavity, the second external reagent can be clamped by the triangular protrusion 134, thereby preventing the second external reagent from shaking or even tipping over during the rotation of the outer ring tray 13, thus improving the safety and accuracy during the operation process.

[0056] In an exemplary embodiment of the present disclosure, the end face of the protrusion 134 facing away from the outer ring bottom plate 131 numbers the second external reagent by printing. Specifically, in the process of placing the second external reagent, since there are multiple outer ring partition members 133 and multiple second external reagents are placed in the outer ring accommodating cavity, during the detection of the second external reagent, it is necessary to clearly identify and record the detected second external reagent and distinguish it from other detected second external reagents. Since the end face of the protrusion 134 facing away from the outer ring bottom plate 131 numbers the second external reagent by printing, the detected second external reagent can be marked by recording the number on the end face of the protrusion 134, thereby facilitating the detection and recording by the operator.

[0057] As an alternative embodiment, the protrusion 134 numbers the second external reagent by screen printing. Specifically, since the protrusion 134 numbers the second external reagent by screen printing, the ink used in screen printing is usually specially treated and has good weather resistance and wear resistance. It can maintain the quality of the printed matter for a long time, is not easily faded or worn, thereby improving the durability of the numbering of the second external reagent. In addition, screen printing can achieve high-resolution pattern and text output, with bright colors and high clarity. The ink used in screen printing has good quality, strong color stability, and good durability, and can maintain the quality of the printed matter for a long time, which can facilitate the operator's observation and recording of the numbering. At the same time, the screen printing equipment is easy to operate and has high production efficiency. Compared with other printing technologies, screen printing can achieve rapid mass production and is suitable for large-scale printing requirements in industrial production.

[0058] In an exemplary embodiment of the present disclosure, the diameter of the first through hole 1321 is smaller than the length of the side of two adjacent outer ring spacers 133 close to the center of the outer ring bottom plate 131. Specifically, since the diameter of the first through hole 1321 is smaller than the length of the side of two adjacent outer ring spacers 133 close to the center of the outer ring bottom plate 131, after the second external reagent is placed in the outer ring accommodation cavity, the second external reagent can be prevented from moving along the side of the outer ring spacer 133 close to the center of the outer ring bottom plate 131, thereby avoiding affecting the rotation of the inner ring tray 12 and improving the safety and stability during the operation process.

[0059] In an exemplary embodiment of the present disclosure, both the inner ring tray 12 and the outer ring tray 13 are integrally formed structures. Specifically, since both the inner ring tray 12 and the outer ring tray 13 are integrally formed structures, the integrally formed inner ring tray 12 and outer ring tray 13 have strong integrity and will not be deformed or loosened due to the loosening of the connection, ensuring the structural stability of the tray. In addition, the integrally formed design can make the inner ring tray 12 and the outer ring tray 13 more solid, capable of bearing greater weight and pressure, and improving the load-bearing capacity of the inner ring tray 12 and the outer ring tray 13. At the same time, the integrally formed tray structure does not require connection methods such as bolts and welding, avoiding problems such as loosening and falling off of components, reducing the frequency of maintenance and replacement, and extending the service life of the inner ring tray 12 and the outer ring tray 13.

[0060] In an exemplary embodiment of the present disclosure, a plurality of first through holes 1321 are uniformly distributed circumferentially along the outer ring connector 132 between two adjacent outer ring separators 133. Specifically, since the plurality of first through holes 1321 are uniformly distributed circumferentially along the outer ring connector 132 between two adjacent outer ring separators 133, the first cooling medium can be evenly transmitted during the process of entering the inner ring tray 12 through the first through holes 1321, so that the first cooling medium is evenly transmitted to the inner ring accommodation cavity of the inner ring tray 12, thereby improving the preservation effect of the first external reagent and the second external reagent.

[0061] According to one aspect of the present disclosure, a biochemical analyzer is provided, including a reagent tray assembly 1. Specifically, a biochemical analyzer is an instrument device used for analyzing and detecting biological samples. It is mainly used for measuring and analyzing chemical components, biochemical parameters, and related indicators in biological samples. Biochemical analyzers can be applied in fields such as medicine, biological science research, clinical diagnosis, and drug development. Biochemical analyzers generally operate based on principles such as optics, electrochemistry, and biosensing. By measuring and analyzing specific molecules, chemical substances, or biological indicators in biological samples, relevant data and results can be obtained. It can provide information about metabolites, enzyme activities, hormone levels, protein contents, etc. in samples such as blood, urine, and body fluids, thereby helping doctors, researchers, or drug developers make diagnoses, evaluate health conditions, or monitor treatment effects. Since the biochemical analyzer includes the reagent tray assembly 1, the preservation effect of the first external reagent and the second external reagent can be improved through the reagent tray assembly 1, so that the accuracy of detecting the first external reagent and the second external reagent can be improved during the process of detecting the first external reagent and the second external reagent by the biochemical analyzer.
