Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a reagent bottle and its application in reagent kits and reagent storage components. Background Technology

[0002] Currently, most immunodiagnostic tests use automated analysis systems to test patient samples. During the testing process, the test reagents in the automated analysis system must be mixed before testing. However, in the existing technology, in order to facilitate the preparation of reagent bottles, the stirring ribs inside the reagent bottles used to hold the test reagents are generally integrated with the reagent bottles. The stirring ribs are mostly rectangular or trapezoidal in shape, and multiple stirring ribs are evenly distributed inside the reagent bottles. During the use of this structure, it has been found that there is a problem of insufficient uniformity of the reagents mixed by the stirring ribs in the reagent bottle. Summary of the Invention

[0003] The purpose of this application is to provide a reagent bottle and the reagent kit and reagent storage component thereof, so as to solve the technical problem of insufficient reagent uniformity after the reagents in the reagent bottle are mixed.

[0004] Firstly, this application provides a reagent bottle,

[0005] The reagent bottle has a hollow body, and at least two stirring ribs are fixedly arranged at intervals inside. The stirring ribs extend upward from the bottom of the bottle body along the elongation direction of the bottle body. The outer wall of the stirring ribs has a turbulent surface with alternating concave and convex surfaces. The turbulent surface has at least one convex part and at least one concave part. The convex parts and the concave parts are arranged alternately along the extension direction of the stirring ribs. At the same height, the convex part or the concave part of one stirring rib corresponds to the concave part or the convex part of the adjacent stirring rib.

[0006] Furthermore, at least two stirring ribs are arranged inside the bottle body around the central axis of the bottle body, and the turbulence surface of each stirring rib is arranged facing the central axis.

[0007] Furthermore, the stirring rib is integrally formed and fixedly connected to the inner wall of the bottle body, or the side wall of the stirring rib is inserted into the inner wall of the bottle body and fixedly connected.

[0008] Furthermore, the bottle body is configured as a cylindrical shape;

[0009] The elongation height of the stirring rib is 50% to 70% of the height of the inner cavity of the bottle;

[0010] The thickness of the stirring rib is 30% to 50% of the thickness of the bottle wall;

[0011] The width of the stirring rib is 10% to 20% of the inner diameter of the bottle body.

[0012] Furthermore, the elongation height of the stirring rib is 60% of the height of the inner cavity of the bottle;

[0013] The thickness of the stirring rib is 40% of the thickness of the bottle wall;

[0014] The width of the stirring rib is 17% of the inner diameter of the bottle body.

[0015] Furthermore, the turbulent surface is configured as a sawtooth or wave-like structure, and the convex part of the turbulent surface is toothed. The tooth is an angle with a pointed tip, or a rectangle or arc with a gentle surface. The maximum protrusion height of the tooth is less than or equal to 60% of the width of the stirring rib.

[0016] Furthermore, the bottle body is cylindrical, and the outer wall of the bottle body is provided with a locking part.

[0017] The engaging portion is configured as an annular groove circumferentially arranged around the lower part of the outer wall of the bottle, or the engaging portion is configured as at least two protrusions circumferentially arranged around the outer wall of the bottle, or an annular protrusion arranged circumferentially.

[0018] Furthermore, the upper part of the bottle body extends outward and is provided with a limiting part, which is configured as a limiting protrusion, or multiple protrusions arranged around the circumference, or an annular protruding outer edge arranged around the circumference.

[0019] Secondly, this application provides a reagent kit containing a reagent bottle as described in any of the preceding claims, comprising a housing and a reagent bottle mounting position disposed within the housing, wherein the reagent bottle is mounted on the reagent bottle mounting position, and the reagent bottle mounting position is provided with a locking protrusion or a locking groove for engaging the reagent bottle.

[0020] The outer wall of the housing is provided with a first snap-fit ​​position and a second snap-fit ​​position on opposite side walls.

[0021] Thirdly, this application provides a reagent storage component, including the aforementioned reagent kit, and further including a reagent turntable and a turntable driving component for driving the reagent turntable to rotate. The reagent turntable is provided with at least one reagent kit mounting slot along its circumference for mounting the reagent kit. The reagent kit mounting slot is provided with a locking position for engaging with the first locking position and the second locking position. The bottom of the reagent kit mounting slot is also rotatably connected to a reagent mixing mechanism.

[0022] Compared with existing technologies, the reagent bottle and its application in the reagent kit and reagent storage assembly provided in this application have at least two stirring ribs inside the reagent bottle. The outer wall of the stirring ribs has a continuous turbulent surface with alternating concave and convex surfaces. The convex and concave parts are arranged alternately along the extension direction of the stirring ribs, and at the same height, the concave parts of two adjacent stirring ribs are arranged opposite the convex parts, and the convex parts are arranged alternately opposite the concave parts. This arrangement allows the liquid inside the reagent bottle to rotate in a spiral-like manner when the bottle is rotated horizontally, which can better create a turbulent state, facilitate the mixing of the reagent, and enhance the uniformity of the reagent mixing.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0055] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0056] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0057] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0058] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

[0060] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0061] like Figures 1 to 5As shown in the figure, this application provides a reagent bottle 100 and its application reagent kit 200 and reagent storage component. The reagent kit 200 includes a housing 202, and at least one reagent bottle mounting position 201 is provided in the housing 202 for mounting at least one reagent bottle 100. The figure shows an example of three reagent bottles 100 mounted side by side. The opposite side walls of the outer wall of the housing 202 of the reagent kit 200 may also be provided with a first snap-fit ​​position 2021 and a second snap-fit ​​position 2022 for snap-fit ​​with the reagent storage component. The reagent storage assembly is used to store the reagent kit 200. The reagent storage assembly may include a reagent turntable 300 and a turntable drive assembly for driving the reagent turntable 300 to rotate. The reagent turntable 300 may be provided with at least one reagent kit mounting slot 301 along its circumference for mounting the reagent kit 200. The reagent kit mounting slot 301 is also provided with engagement positions on opposite sides for engaging with the aforementioned first engagement position 2021 and second engagement position 2022. The reagent kit mounting slot 301 may also be provided with a protrusion 3011 for engaging with the reagent bottle 100 inside the reagent kit 200, for engaging with the reagent bottle 100 and driving it to rotate horizontally for mixing. Correspondingly, the bottom surface of the bottle body 10 of the reagent bottle 100 may be provided with at least one groove for engaging with the protrusion 3011. The bottom of the reagent kit mounting slot 301 is also rotatably connected to a reagent mixing mechanism, which is used to drive the reagent bottle 100 to rotate horizontally for mixing.

[0062] like Figure 2 and Figure 3 As shown, the reagent bottle 100 provided in this application may include a bottle body 10 and a cap 20 that covers the top opening of the bottle body 10. The bottle body 10 is hollow and has at least two stirring ribs 11 fixedly arranged at intervals inside. The stirring ribs 11 extend upward from the bottom of the bottle body 10 along the elongation direction of the bottle body 10. The outer wall of the stirring rib 11 has a turbulent surface 111 with alternating concave and convex surfaces. The turbulent surface 111 may be configured as a sawtooth structure or a wave-like structure. The turbulent surface 111 has at least one protrusion 111a and at least one concave portion 111b. The protrusions 111a and concave portions 111b are arranged alternately along the extension direction of the stirring ribs 11, and at the same height, the protrusion 111a or concave portion 111b of one stirring rib 11 corresponds to the concave portion 111b or protrusion 111a of the adjacent stirring rib 11. This configuration allows the liquid inside the reagent bottle 100 to rotate in a spiral-like manner when the bottle is rotated horizontally, which better facilitates the mixing of the reagent and enhances the uniformity of the mixture.

[0063] In one specific embodiment, two stirring ribs 11 can be arranged opposite each other inside the body 10 of the aforementioned reagent bottle 100, and the turbulent surfaces 111 of the two stirring ribs 11 can be arranged opposite each other; or at least three stirring ribs 11 can be arranged around the central axis of the body 10 inside the body 10, and the turbulent surfaces 111 of each stirring rib 11 can be arranged facing the central axis. The multiple stirring ribs can be evenly spaced or unevenly spaced. Evenly spaced ribs can further improve the turbulence effect, which is more conducive to reagent mixing and enhances the uniformity of reagent mixing.

[0064] Another specific embodiment is that the bottom of the aforementioned stirring rib 11 can be fixedly connected to the bottom of the body 10 of the reagent bottle 100. Specifically, the two can be integrally formed and fixedly connected, or they can be inserted and fixedly connected. For example... Figure 2 As shown, in one optional embodiment, the aforementioned stirring rib 11 can be separately disposed from the inner wall of the bottle body 10 with a gap, which facilitates the disassembly, cleaning, and maintenance of the stirring rib 11 together with the bottom of the bottle body 10. Figure 3 As shown, another optional embodiment is that the stirring rib 11 can be fixedly connected to the inner wall of the bottle body 10. Specifically, it can be integrally formed and fixedly connected, or it can be inserted and fixedly connected. This connection is more stable, and compared with the aforementioned separate setting where the stirring rib 11 and the inner wall of the bottle body 10 are spaced apart, it can prevent liquid from flowing through the gap between the stirring rib 11 and the inner wall of the bottle body 10, thus avoiding a reduction in the degree of mixing.

[0065] Preferably, the body 10 of the aforementioned reagent bottle 100 can be cylindrical to facilitate horizontal rotation within the reagent kit 200. For example... Figure 6 As shown in Table 1 below, to achieve better mixing, the structure of the stirring rib can be further optimized. Specifically, the elongation height h of the aforementioned stirring rib 11 can be 50% to 70% of the inner cavity height of the bottle body 10. Compared to being too low or too high, this height range results in better turbulence and better reagent mixing. Furthermore, the test data in Table 1 shows that the best effect is achieved when the elongation height h of the stirring rib 11 is 60% of the inner cavity height of the bottle body 10. Additionally, the thickness b of the stirring rib 11 is preferably 30% to 50% of the wall thickness of the bottle body 10. To ensure both the strength of the stirring rib 11 and the mixing effect of the reagent, and as shown in the test data in Table 1 below, the effect is best when the thickness b of the stirring rib 11 is 40% of the wall thickness of the bottle body 10. In addition, the width c of the stirring rib 11 is preferably 10% to 20% of the inner diameter of the bottle body 10. Through experimental comparison, the width c of the stirring rib 11 within this range can achieve a better reagent mixing effect. And as shown in the test data in Table 1 below, the effect is best when the width c of the stirring rib 11 is 17% of the inner diameter of the bottle body 10.

[0066] Furthermore, such as Figure 6As shown in Table 1 below, the protrusion 111a of the turbulent surface 111 of the aforementioned stirring rib 11 can be referred to as tooth-shaped. Specifically, the tooth-shaped part can be a angular shape with a pointed tip, or a rectangle or arc shape with a gentle plane. In order to ensure a better mixing effect, it is preferable that the maximum protrusion height a of the tooth-shaped part is less than or equal to 60% of the width b of the stirring rib 11. The tooth-shaped part is preferably triangular. When the maximum protrusion height a is 60% of the width c of the stirring rib 11, the mixing effect can be best.

[0067] The following provides a data reference for a mixing effect test. This test uses a relatively large magnetic chip with dimensions of 60*40*7μm. The number of magnetic beads is counted using a reading device to test the mixing effect in reagent bottles under the 14 schemes described in Table 1. First, equal volumes of magnetic bead solution of the same concentration are placed in reagent bottles numbered 1-12 (different stirring rib schemes) and traditional reagent bottles numbered 12-14. For reagent bottles numbered 1-11, the stirring ribs have triangular teeth with a maximum protrusion height a = c * 60%. For traditional reagent bottles numbered 12-14, the stirring ribs have a flat end face. Then, the reagent bottles are mixed by rotating them with the same parameters (same rotation speed and duration). Equal volumes of solution are then taken from each reagent bottle using a pipette and placed into the reading device to count the number of magnetic beads. At least five consecutive tests are performed, and the average number is calculated. The theoretical number of magnetic beads in this volume of solution is 850. Table 1 below shows the statistical data on the number of magnetic beads in the solution for each scheme:

[0068] Table 1: Statistics on the Number of Magnetic Chips

[0069] Serial Number h ratio b ratio c ratio Mixing rib shape and height Number of magnetic chips Difference 1 50％ 30％ 10％ Triangular tooth shape, height = c * 60% 868 +18 2 50％ 40％ 17％ Triangular tooth shape, height = c * 60% 860 +10 3 50％ 50％ 20％ Triangular tooth shape, height = c * 60% 862 +12 4 60％ 30％ 17％ Triangular tooth shape, height = c * 60% 838 -12 5 60％ 40％ 20％ Triangular tooth shape, height = c * 60% 840 -10 6 60％ 50％ 10％ Triangular tooth shape, height = c * 60% 834 -17 7 70％ 30％ 20％ Triangular tooth shape, height = c * 60% 831 -19 8 70％ 40％ 10％ Triangular tooth shape, height = c * 60% 837 -13 9 70％ 50％ 17％ Triangular tooth shape, height = c * 60% 830 -20 10 60％ 40％ 17％ Triangular tooth shape, height = c * 60% 843 -7 11 70％ 50％ 20％ Triangular tooth shape, height = c * 60% 821 -29 12 70％ 50％ 20％ flat 793 -57 13 60％ 40％ 17％ flat 810 -40 14 50％ 30％ 10％ flat 880 +30

[0070] As can be seen from the data in Table 1, the number of magnetic chips in Scheme 10 is closest to the theoretical value, which means it can achieve the relatively optimal mixing effect of the magnetic chips. Furthermore, the data shows that the height h of the stirring rib is 60% of the inner cavity height of the reagent bottle, the thickness b of the stirring rib is 40% of the wall thickness of the reagent bottle, and the radial width c of the stirring rib is 17% of the inner cavity diameter of the reagent bottle.

[0071] like Figure 1 and Figure 3As shown, the outer wall of the body 10 of the reagent bottle 100 may be provided with a locking part. Specifically, the locking part may be configured as an annular groove 12 circumferentially arranged around the lower part of the outer wall of the body 10 of the reagent bottle 100. Correspondingly, the reagent bottle mounting position 201 of the aforementioned reagent kit 200 may be provided with a locking protrusion 2011 that engages with the annular groove 12. The locking protrusion 2011 may be at least two protrusions arranged circumferentially or an annular protrusion arranged circumferentially. Alternatively, the locking part may be provided with at least two protrusions arranged circumferentially around the outer wall of the body 10 of the reagent bottle 100 or an annular protrusion arranged circumferentially. Correspondingly, the reagent bottle mounting position 201 may be provided with an annular locking groove that engages with the at least two protrusions or the annular protrusion. Preferably, when two protrusions are provided, the two protrusions are symmetrically arranged. This method of interlocking and connecting the annular groove with the annular protrusion or with at least two circumferentially oriented protrusions serves both as a limiting and engaging connection and does not affect the rotation and mixing of the reagent bottle 100 within the reagent kit 200. Preferably, the annular groove 12 has an annular upper top surface 121, an annular lower bottom surface, and a connecting wall connecting the annular upper top surface 121 and the annular lower bottom surface. Preferably, the annular upper top surface 121 is arc-shaped to improve the smoothness during rotation.

[0072] Furthermore, the top of the aforementioned bottle body 10 may be provided with an annular thread 14, and the bottle cap 20 is threadedly connected and fixed to the top of the bottle body 10. Additionally, an EP film 15 and a cross-shaped silicone film 16 may be sequentially provided on the top of the bottle body 10. The cross-shaped silicone film 16 may be positioned close to the top of the bottle cap 20, and the bottle cap 20 may have a notch 21 corresponding to the cross-shaped silicone film 16, allowing the cross-shaped silicone film 16 to be exposed.

[0073] Preferably, the upper part of the aforementioned bottle body 10 may extend outward to provide a limiting part 13. The limiting part 13 may be configured as a single limiting protrusion, or multiple limiting protrusions arranged circumferentially, or the outer edge of a circumferentially arranged annular protrusion. The limiting part 13 may be integrally formed with the bottle body 10. Preferably, the limiting part 13 may be arranged circumferentially at the bottom of the aforementioned annular thread 14. Correspondingly, the top of the housing 202 of the reagent kit 200 may abut against the limiting part 13. With this configuration, the limiting part 13 not only serves a limiting function but also protects the entire bottle body 10 of the reagent bottle 100 within the housing 202 of the reagent kit 200, effectively protecting the reagent bottle 100.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
