[0034] In order to facilitate the understanding of the present application, a more comprehensive description of the present application will be given below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0035] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "inner", "outer", "left", "right", and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0036] Referring to Figure 1 and Figure 2 , the reagent storage device 10 provided by an embodiment of the present application includes a pot body 100, a storage mechanism 200, and a refrigeration mechanism 300. The storage mechanism 200 includes at least two storage units 210.

[0037] In some embodiments, the pot body 100 includes a side frame 110, a top cover 120, and a bottom cover 130. The bottom cover 130 and the top cover 120 are both flat plate structures and are arranged horizontally. The side frame 110 is a ring structure and is arranged vertically. The top cover 120 is connected to the upper end of the side frame 110, and the bottom cover 130 is connected to the lower end of the side frame 110. The bottom cover 130, the top cover 120, and the side frame 110 enclose a closed accommodation cavity 101. The cross-sectional shape of the side frame 110 is rectangular or track-shaped, which makes the side frame 110 easy to process and enables the entire pot body 100 to well guarantee the processing precision on the basis of a lower processing cost. The top cover 120 is provided with at least two groups of sampling ports 121. Each group of sampling ports 121 corresponds to a storage unit 210, and is used for a sampling needle to access the storage unit 210 to suck reagents. Each group of sampling ports 121 can be used for the sampling needle to reach a plurality of cavities on a reagent box 212 of the storage unit 210.

[0038] Referring to Figure 2 , Figure 3 andFigure 4 In some embodiments, the storage units 210 can be two or more, and the embodiments are described by taking two storage units 210 as an example. Each storage unit 210 includes a rotating disc 211, a reagent box 212, a mixing gear 213, a rotating shaft 214 and a driver 215. The rotating disc 211, the reagent box 212 and the mixing gear 213 are located in the accommodating cavity 101, and the driver 215 is located outside the accommodating cavity 101. The rotating shaft 214 is arranged through the bottom cover 130 of the pot body 100, the upper end of the rotating shaft 214 is connected with the rotating disc 211, and the lower end of the rotating shaft 214 is located outside the accommodating cavity 101 and connected with the driver 215. The rotating disc 211 is a disc structure, and a plurality of mounting positions are arranged on the rotating disc 211 and spaced along the circumferential direction of the rotating disc 211. The reagent box 212 is in one-to-one correspondence with the mounting positions, and the reagent box 212 is fixed on the mounting positions. The number of mounting positions on each rotating disc 211 can be 15 to 50, for example, the number of mounting positions on each rotating disc 211 can be 25, so that two rotating discs 211 can simultaneously store 50 reagent boxes 212. Each storage unit 210 is loaded with all reagent components required for a corresponding analysis project, so that the sampling needle can suck all reagent components of the analysis project on the same storage unit 210, preventing the need for a single analysis project to suck reagents from two storage units 210, thereby effectively avoiding problems such as low efficiency of sucking reagents for the same project and inconvenience of loading and unloading the reagent box 212.

[0039] The driver 215 is used to drive the rotating shaft 214 to rotate, and in turn drive the rotating disc 211 to rotate. When the rotating disc 211 rotates around the rotating shaft 214, the relative position of the reagent box 212 and the rotating disc 211 remains constant, and the reagent box 212 rotates around the rotating shaft 214 with the rotating disc 211.

[0040] Meanwhile, referring to Figure 5 and Figure 6 , the reagent box 212 includes a box body 212a, a rotating reagent bottle 212b, a homogeneous reagent bottle 212c and a transmission gear. The box body 212a is arranged on the mounting position of the rotating disc 211, and a plurality of cavities can be formed in the box body 212a. The rotating reagent bottle 212b and the homogeneous reagent bottle 212c are accommodated in different cavities. The number of homogeneous reagent bottles 212c can be multiple, and each homogeneous reagent bottle 212c contains reagents of a specific composition. The reagents contained in the homogeneous reagent bottle 212c are referred to as homogeneous reagents. For the homogeneous reagent bottles 212c on the same box body 212a, the homogeneous reagents contained in different homogeneous reagent bottles 212c have different compositions. The homogeneous reagents are usually in a solution state. During the rotation of the reagent box 212 with the rotating disc 211, the homogeneous reagent bottle 212c remains stationary in the cavity, and the homogeneous reagent bottle 212c does not rotate relative to the box body 212a.

[0041] The number of the rotating reagent bottle 212b can be one, and the rotating reagent bottle 212b is placed in the most edge cavity of the box 212a, which is closer to the mixing gear 213 than other cavities. The rotating reagent bottle 212b is used to contain the reagent in the form of suspension, which is referred to as solid-phase reagent, and for the solid-phase reagent, the solid magnetic particles are in the state of suspension. The rotating reagent bottle 212b can be cylindrical, and of course, the cavity accommodating the rotating reagent bottle 212b can also be cylindrical, and the rotating reagent bottle 212b is inserted into the cylindrical cavity, the transmission gear is connected or mounted at the bottom of the rotating reagent bottle 212b outside the cavity, the transmission gear is an external gear, and the mixing gear 213 can be an internal gear, and the mixing gear 213 is arranged around the rotating disc 211, and the transmission gear and the mixing gear 213 are engaged with each other. Therefore, when the rotating shaft 214 drives the rotating disc 211 to rotate, the box 212a rotates with the rotating disc 211 to revolve around the rotating shaft 214, so that both the rotating reagent bottle 212b and the homogeneous reagent bottle 212c revolve around the rotating shaft 214, and at the same time, due to the engagement between the transmission gear at the bottom of the rotating reagent bottle 212b and the mixing gear 213, the mixing gear 213 drives the rotating reagent bottle 212b to rotate around its central axis relative to the box 212a through the transmission gear, that is, the rotating reagent bottle 212b rotates around its central axis in the box 212a.

[0042] Therefore, when the rotating shaft 214 drives the rotating disc 211 to rotate, the rotating reagent bottle 212b can revolve and rotate at the same time, and the revolving and rotating movements can make the suspension in the rotating reagent bottle 212b oscillate more strongly, so that the solid-phase reagent in the form of suspension forms a turbulent flow, and finally the solid magnetic particles in the solid-phase reagent are always in the state of suspension, that is, the solid-phase reagent is mixed, and the solid magnetic particles are prevented from precipitating at the bottom of the rotating reagent bottle 212b, so that the solid-phase reagent extracted by the sampling needle contains a certain proportion of solid magnetic particles, so as to ensure the accuracy of the subsequent test results. The homogeneous reagent bottle 212c does not need to be mixed, because the homogeneous reagent bottle 212c contains homogeneous reagent in the form of solution.

[0043] Referring to Figure 6The mixing gear 213 is a circular gear. The mixing gear 213 can not be formed by one-piece machining, but can be formed by splicing a plurality of arc-shaped gear racks 213a. The arc-shaped gear racks 213a have small sizes, which can reduce the manufacturing cost of related molds or clamps, and reduce the machining difficulty, so as to easily ensure the machining precision and machining efficiency of the single arc-shaped gear rack 213a. When the arc-shaped gear racks 213a are spliced to form the mixing gear 213, the size and shape accuracy of the spliced mixing gear 213 can also be ensured. Therefore, after the plurality of arc-shaped gear racks 213a with high machining precision and efficiency are spliced to form the mixing gear 213, the total manufacturing cost of the mixing gear 213 can be effectively reduced, and the machining efficiency and machining precision of the mixing gear 213 can be improved.

[0044] Referring to Figure 3 and Figure 4 The driver 215 is located below the bottom cover 130, and the rotating disc 211 is located above the bottom cover 130, so that the driver 215 and the rotating disc 211 are located on opposite sides of the bottom cover 130. The driver 215 includes a support plate 140, a motor 215a, a driving wheel 215b, a driven wheel 215c and a synchronous belt 215d. The motor 215a, the driving wheel 215b and the driven wheel 215c are all arranged on the support plate 140, and the support plate 140 bears and installs the motor 215a, the driving wheel 215b and the driven wheel 215c. The motor 215a can be a servo motor 215a or a stepping motor 215a. The motor 215a rotates intermittently. The driving wheel 215b is connected with the output shaft of the motor 215a. The driven wheel 215c is connected with the lower end of the rotating shaft 214. The synchronous belt 215d is sleeved on the driving wheel 215b and the driven wheel 215c. The diameter of the driven wheel 215c is greater than that of the driving wheel 215b, so that the driven wheel 215c decelerates the motion output by the driving wheel 215b, and improves the torque of the driven wheel 215c. When the motor 215a rotates, the rotating disc 211 can be driven to move intermittently by the rotating shaft 214. When the motor 215a drives the rotating disc 211 to stop moving, the sampling needle can suck the solid-phase reagent and the homogeneous-phase reagent in the rotating reagent bottle 212b and the homogeneous reagent bottle 212c, so as to be measured and analyzed subsequently. In some embodiments, the two rotating discs 211 independently and alternately transfer the target reagent box 212 thereon to below the corresponding sampling port every fixed time, so that the corresponding sampling needle sucks the reagent. In this way, the requirement for the rotating speed of the rotating disc 211 can be further reduced, the load requirement for driving can be further reduced, and the difficulty of driving control can be reduced.

[0045] For the traditional reagent storage device 10, in order to increase the reagent storage capacity to adapt to high test throughput (the number of test results per unit time), the number of reagent boxes 212 carried by the turntable 211 and the total weight of the turntable 211 and the reagent boxes 212 carried by the turntable 211 increase by increasing the number of mounting positions on the turntable 211, which in turn causes the load of the driver 215 to be too large, thereby increasing the difficulty of driving control technology of the driver 215. In addition, it is difficult to ensure the machining precision of the turntable 211 due to the excessive size of the turntable 211.

[0046] For the reagent storage device 10 in the above embodiment, by providing two storage units 210 on the same pot body 100, i.e. two turntables 211 in the accommodation cavity 101, since the number of turntables 211 increases, the total number of mounting positions of the two turntables 211 increases while the number of mounting positions of a single turntable 211 remains unchanged or even decreases, so that the number of reagent boxes 212 carried by the entire reagent storage device 10 can also be increased, thereby meeting the requirement of test throughput. In this way, the single turntable 211 can have a reasonable size, thereby ensuring the machining precision of the turntable 211, and the total weight of the single turntable 211 and the reagent boxes 212 carried by the turntable 211 is within a reasonable range, effectively preventing the phenomenon that the load of the driver 215 is too large and the control technology difficulty is increased. Therefore, by sharing one pot body 100 for two turntables 211, on the basis of increasing the total number of reagent boxes 212 to adapt to the measurement throughput, not only does each turntable 211 have a relatively reasonable size, but also helps to reduce the volume of the entire reagent storage device 10, making the reagent storage device 10 more compact in structure, while reducing the difficulty of motion control of the turntable 211.

[0047] Since two independent storage units 210 are provided, when one of the storage units 210 fails, the other storage unit 210 can continue to work, avoiding the phenomenon that the traditional reagent storage device 10 cannot work at all due to the failure of one storage unit 210, thereby improving the reliability and tolerance of the entire reagent storage device 10. Of course, in the case where one of the storage units 210 continues to work, the failed storage unit 210 can be repaired so as to subsequently restore the state that both storage units 210 can be used simultaneously.

[0048] Meanwhile refer to Figure 1 , Figure 2 and Figure 7In some embodiments, the refrigeration mechanism 300 comprises cold end units 310, hot end units 320, refrigeration fins 330, heat insulation plates 340 and heat dissipation air ducts 323. The cold end units 310 are located in the accommodating cavity 101, and the hot end units 320 and the heat dissipation air ducts 323 are located outside the accommodating cavity 101. The number of the cold end units 310 is at least two, for example, the number of the cold end units 310 is even and is divided into one or more pairs. The at least two cold end units 310 are symmetrically distributed along the connecting line of the centers of the at least two rotating disks 211 or the vertical midline of the connecting line of the centers of the at least two rotating disks 211. In this way, it is not only beneficial to improve the refrigeration efficiency, but also beneficial to maintain the temperature uniformity of each point in the accommodating cavity 101. In one embodiment, referring to Figure 5 The cold end units 310 are located in the gap between the two rotating disks 211 and are symmetrically distributed along the connecting line of the centers of the two rotating disks 211. In this way, not only the space between the two rotating disks 211 in the accommodating cavity 101 is fully utilized, but also the layout of the entire device is facilitated, so that the limited accommodating cavity 101 can accommodate more components, thereby reducing the volume of the entire pot body 100.

[0049] The cold end unit 310 comprises a cold end heat dissipation fin 311, a cold end fan 312 and a mounting seat 313. The cold end heat dissipation fin 311 is connected with the cold end of the refrigeration fin 330, the mounting seat 313 is connected with the cold end heat dissipation fin 311 and is close to the bottom cover 130 of the pot body 100, and the cold end fan 312 is fixed on the mounting seat 313. The hot end unit 320 comprises a hot end heat dissipation fin 321 and a hot end fan 322. The hot end heat dissipation fin 321 is connected with the bottom cover 130 of the pot body 100 and is used to absorb the heat of the hot end of the refrigeration fin 330. The number of the hot end fan 322 is at least two. When the number of the hot end fan 322 is two, the two hot end fans 322 are respectively fixed on the two ends of the hot end heat dissipation fin 321. The heat dissipation air duct 323 is connected with the end of the hot end heat dissipation fin 321. The hot end heat dissipation fin 321 is arranged around the hot end fan 322, and the hot end fan 322 discharges the heat of the hot end heat dissipation fin 321 from the heat dissipation air duct 323. For the same hot end unit 320, the number of the heat dissipation air duct 323 can be two, that is, one heat dissipation air duct 323 is connected with each end of the hot end heat dissipation fin 321. Of course, the number of the heat dissipation air duct 323 can be one, that is, only one end of the hot end heat dissipation fin 321 is connected with the heat dissipation air duct 323. The heat dissipation air duct 323 is located below the pot body 100, so that the space on the side of the pot body 100 can be saved, leaving space for the arrangement of other devices of the entire device. Further, the heat dissipation air duct 323 is located below the center of the pot body 100 and passes through the gap between the two drivers 215, so that the space of the entire device is further saved.

[0050] The bottom cover 130 can be provided with a through hole, and the heat insulation plate 340 and the refrigeration sheet 330 can be installed in the through hole, so that the heat insulation plate 340 and the refrigeration sheet 330 are clamped between the hot end heat dissipation sheet 321 and the cold end heat dissipation sheet 311. The refrigeration sheet 330 can be a Peltier refrigeration sheet 330 made of a semiconductor material. When the refrigeration mechanism 300 works, the cold end of the refrigeration sheet 330 generates a refrigeration effect, which is transmitted to the accommodation cavity 101 through the cold end heat dissipation sheet 311, and the heat of the hot end of the refrigeration sheet 330 is transmitted to the hot end heat dissipation sheet 321, and the hot end fan 322 can discharge the heat from the heat dissipation air duct 323 to the outside. For the same pair of cold end units 310, the blowing directions of the cold end fans 322 are opposite. For example, the cold end fan 312 on one of the cold end units 310 is used to draw air from the cold end heat dissipation sheet 311, and the cold end fan 312 on the other cold end unit 310 is used to send air to the cold end heat dissipation sheet 311, which can accelerate the circulation of air in the accommodation cavity 101, thereby improving the refrigeration effect in the accommodation cavity 101, ensuring that the temperature of each space in the accommodation cavity 101 is the same, and ensuring that all reagents in the reagent boxes 212 are kept at the same temperature. In addition, the two rotating discs 211 drive the reagent boxes 212 thereon to rotate independently, which can stir the air in the accommodation cavity 101, further accelerate the flow of cold air, and maintain temperature uniformity.

[0051] Since the two storage units 210 share one pot body 100, the two rotating discs 211 are located in the same accommodation cavity 101 in the same pot body 100, and the refrigeration mechanism 300 is connected with the pot body 100, when the refrigeration mechanism 300 generates a refrigeration effect to keep the accommodation cavity 101 at a set temperature (2-8 degrees Celsius), the reagent boxes 212 on the two rotating discs 211 are located in the same temperature refrigeration environment (the accommodation cavity 101), so that all reagent components in all reagent boxes 212 are kept at the same temperature, thereby ensuring the temperature consistency of the reagents stored in the whole reagent storage device 10, reducing the influence on the performance of the reagents due to the temperature inconsistency, and thereby ensuring the accuracy of the subsequent test results. Moreover, the two cold end units 310 share the same heat dissipation air duct 323, which can reduce the number of heat dissipation air ducts 323, thereby making the reagent storage structure more compact. Furthermore, the cold end units 310 are located in the gap between the two rotating discs 211, and the hot end heat dissipation sheet 321 is located below the cold end heat dissipation sheet 311, which is more conducive to the overall layout of the hot end heat dissipation sheet 321 and the heat dissipation air duct 323 in space.

[0052] Referring to Figure 7In some embodiments, the reagent storage device 10 further comprises scanners 400 arranged on the inner wall surface of the side frame 110, such that the scanners 400 are located in the accommodation cavity 101 of the pot body 100, i.e. the scanners 400 can make full use of the existing installation space of the accommodation cavity 101 without occupying the installation space outside the accommodation cavity 101, thereby improving the structural compactness of the reagent storage device 10. The number of scanners 400 can be equal to the number of turntables 211, i.e. each turntable 211 corresponds to one scanner 400. The scanners 400 are used to scan the barcodes on the reagent boxes 212, thereby identifying the barcode information on the reagent boxes 212 to identify and distinguish the reagents of different analysis items. The scanners 400 adopt a fixed design, i.e. the scanners 400 are directly fixedly connected with the side frame 110, which also makes the reagent storage device 10 more compact in structure and reduces the manufacturing cost.

[0053] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but it should be understood that any combination of the technical features is within the scope of the present disclosure as long as there is no contradiction.

[0054] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
