Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a reagent container. Background Art

[0002] The operating speed of current testing instruments is getting faster and faster, and the time reserved for the reagent container to move from the storage position to the sampling position is getting shorter and shorter. The long-distance movement of the reagent in the reagent container in a very short time will cause a large amplitude of oscillation of the liquid level of the reagent in the reagent container, resulting in the generation of bubbles, and it is easy to have problems such as inaccurate sampling or empty suction during the liquid level oscillation, which is not conducive to the smooth progress of sample testing. Summary of the Invention

[0003] In view of this, the present invention provides a reagent container.

[0004] The reagent container provided by the present invention includes:

[0005] A container body, the container body includes a first bottom wall, a first side wall, a second side wall, a third side wall and a fourth side wall. The first side wall and the second side wall are oppositely arranged in a first direction, the third side wall and the fourth side wall are oppositely arranged in a second direction, the first direction is perpendicular to the second direction, and the first bottom wall, the first side wall, the second side wall, the third side wall and the fourth side wall form a first reagent cavity with an opening;

[0006] A first baffle, the first baffle is arranged in the first reagent cavity and is connected to the first bottom wall and the first side wall. The first baffle extends from the first side wall towards the second side wall and does not extend to the second side wall;

[0007] A second baffle, the second baffle is arranged in the first reagent cavity and is connected to the first bottom wall and the second side wall. The second baffle extends from the second side wall towards the first side wall and does not extend to the first side wall;

[0008] Wherein, the first baffle and the second baffle are staggered and arranged in the first reagent cavity, and the projections of the first baffle and the second baffle on a plane perpendicular to the second direction at least partially overlap.

[0009] As can be seen from the above technical solutions, for the reagent container proposed by the present invention, by providing a first baffle and a second baffle in the first reagent chamber, when the reagent container is being dispatched and the reagent contained in the first reagent chamber moves in the second direction, the first baffle and the second baffle can block the reagent, preventing the reagent from obtaining a large kinetic energy and causing large-amplitude oscillations in the first reagent chamber, thereby reducing the generation of bubbles. Moreover, since the oscillation amplitude of the reagent in the first reagent chamber is small, the calm time of the reagent liquid level can be shortened, and the influence of the oscillation of the reagent liquid level on the detection speed of the sample analyzer can be reduced.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1 shown, an embodiment of the present invention proposes a reagent container 100. The reagent container 100 is a consumable used in an immunoassay analyzer, and various reagents used in the immunoassay analyzer are stored therein. The reagent container 100 is a disposable consumable and will be discarded after use. The reagent container 100 of the present invention is used in cooperation with the reagent tray of the immunoassay analyzer to process the sample to be tested. When in use, the reagent container 100 is placed on the reagent carrying component, and the reagent needle of the immunoassay analyzer can move above the reagent carrying component and extend into the reagent container 100 of the reagent carrying component to suck the reagent. After the reagent in the reagent container 100 is consumed, a new reagent container 100 is replaced.

[0024] As Figure 1 and Figure 2 shown, in one embodiment, the reagent container 100 includes a container body 10, a first baffle 20, and a second baffle 30. The container body 10 includes a first bottom wall 11, a first side wall 12, a second side wall 13, a third side wall 14, and a fourth side wall 15. The first side wall 12 and the second side wall 13 are oppositely arranged in the first direction X, the third side wall 14 and the fourth side wall 15 are oppositely arranged in the second direction Y, the first direction X is perpendicular to the second direction Y, and the first bottom wall 11, the first side wall 12, the second side wall 13, the third side wall 14, and the fourth side wall 15 form a first reagent chamber 16 with an opening. The first baffle 20 is arranged in the first reagent chamber 16 and is connected to the first bottom wall 11 and the first side wall 12. The first baffle 20 extends from the first side wall 12 towards the second side wall 13 and does not extend to the second side wall 13. The second baffle 30 is arranged in the first reagent chamber 16 and is connected to the first bottom wall 11 and the second side wall 13. The second baffle 30 extends from the second side wall 13 towards the first side wall 12 and does not extend to the first side wall 12. The first baffle 20 and the second baffle 30 are staggered and arranged in the first reagent chamber 16, and the projections of the first baffle 20 and the second baffle 30 on the plane perpendicular to the second direction Y at least partially overlap.

[0025] Among them, the "staggered and offset" means that the first baffle 20 and the second baffle 30 are not only arranged in a staggered manner, but also an offset forms a gap between the first baffle 20 and the second baffle 30. The first baffle 20 and the second baffle 30 divide the first reagent chamber 16 into two parts of the cavity, and the reagent in one cavity can flow into the other cavity through the gap between the first baffle 20 and the second baffle 30.

[0026] For the reagent container 100 proposed in this embodiment, by arranging the first baffle 20 and the second baffle 30 in the first reagent chamber 16, when the reagent container 100 is being scheduled and the reagent contained in the first reagent chamber 16 moves along the second direction Y, the first baffle 20 and the second baffle 30 can block the reagent, preventing the reagent from obtaining a large kinetic energy and causing large-amplitude oscillations in the first reagent chamber 16, thereby reducing the generation of bubbles. Moreover, since the oscillation amplitude of the reagent in the first reagent chamber 16 is small, the calm time of the reagent liquid level can be shortened, and the influence of the oscillation of the reagent liquid level on the detection speed of the sample analyzer can be reduced.

[0027] Optionally, the container body 10, the first baffle 20 and the second baffle 30 are integrally injection-molded using a plastic material. For example, the container body 10, the first baffle 20 and the second baffle 30 are integrally injection-molded using PP (Polypropylene) material.

[0028] In one embodiment, the first side wall 12 and the second side wall 13 are arranged in parallel, and the third side wall 14 and the fourth side wall 15 are arranged in parallel. The first side wall 12, the second side wall 13, the third side wall 14 and the fourth side wall 15 enclose a rectangular structure. Of course, the first side wall 12 and the second side wall 13 are not limited to being arranged in parallel, and the third side wall 14 and the fourth side wall 15 are not limited to being arranged in parallel. For example, in another embodiment, the first side wall 12 and the second side wall 13 are parallel, and the third side wall 14 and the fourth side wall 15 are not parallel, or vice versa, the first side wall 12 and the second side wall 13 are not parallel, and the third side wall 14 and the fourth side wall 15 are parallel. The first side wall 12, the second side wall 13, the third side wall 14 and the fourth side wall 15 enclose a trapezoidal structure. For another example, in another embodiment, the first side wall 12 and the second side wall 13 are not parallel, and the third side wall 14 and the fourth side wall 15 are not parallel. For another example, in another embodiment, the cross-section of the first reagent chamber 16 is circular, and the first side wall 12, the second side wall 13, the third side wall 14 and the fourth side wall 15 can be regarded as four quarters of a circle. It can be determined specifically according to actual design needs. For another example, in another embodiment, as Figure 3As shown, the first side wall 12 includes a first extension section 121 and a second extension section 122, the second side wall 13 includes a third extension section 131 and a fourth extension section 132, the first extension section 121 and the third extension section 131 are arranged opposite to each other, the second extension section 122 and the fourth extension section 132 are arranged opposite to each other, the third side wall 14 is connected to the first extension section 121 and the third extension section 131, the fourth side wall 15 is connected to the second extension section 122 and the fourth extension section 132, the second extension section 122 and the fourth extension section 132 are parallel, and in the direction of the fourth side wall 15 facing the third side wall 14, the distance between the first extension section 121 and the third extension section 131 gradually decreases.

[0029] As Figure 3 shown, in one embodiment, the distance between the first side wall 12 and the second side wall 13 is less than the distance between the third side wall 14 and the fourth side wall 15. That is, the first baffle 20 and the second baffle 30 are respectively arranged on two longer side walls. The reagent container 100 of this embodiment is applicable to a sample analyzer whose scheduling mechanism schedules the reagent container 100 along the length direction of the first reagent chamber 16. When the scheduling mechanism of this type of sample analyzer schedules the reagent container 100, the reagent in the first reagent chamber 16 has a relatively large kinetic energy in the length direction of the first reagent chamber 16. By arranging the first baffle 20 and the second baffle 30 on two longer side walls respectively to form a block for the reagent moving in the length direction, the oscillation amplitude of the reagent can be effectively prevented from being too high.

[0030] As Figure 4 shown, in another embodiment, the distance between the first side wall 12 and the second side wall 13 is greater than the distance between the third side wall 14 and the fourth side wall 15. That is, the first baffle 20 and the second baffle 30 are respectively arranged on two shorter side walls. The reagent container 100 of this embodiment is applicable to a sample analyzer whose scheduling mechanism schedules the reagent container 100 along the width direction of the first reagent chamber 16, such as a common disc-shaped reagent scheduling mechanism. When the scheduling mechanism of this type of sample analyzer schedules the reagent container 100, the reagent in the first reagent chamber 16 has a relatively large kinetic energy in the width direction of the first reagent chamber 16. By arranging the first baffle 20 and the second baffle 30 on two shorter side walls respectively to form a block for the reagent moving in the width direction, the oscillation amplitude of the reagent can be effectively prevented from being too high.

[0031] As Figure 1As shown, in one embodiment, the first baffle 20 extends obliquely from the first side wall 12 towards the second side wall 13, and the second baffle 30 extends obliquely from the second side wall 13 towards the first side wall 12. Taking the first baffle 20 extending obliquely from the first side wall 12 towards the second side wall 13 as an example, the so-called oblique extension means that the first baffle 20 is not perpendicular to the first side wall 12, but is arranged at an acute angle with the first side wall 12. In this embodiment, by setting the first baffle 20 to extend obliquely from the first side wall 12 towards the second side wall 13 and the second baffle 30 to extend obliquely from the second side wall 13 towards the first side wall 12, when the reagent moves along the second direction Y and impacts the first baffle 20 and the second baffle 30, the oblique settings of the first baffle 20 and the second baffle 30 have the functions of dissipating the force of the reagent and guiding it, which is beneficial to the formation of turbulence of the reagent in the first reagent chamber 16 to reduce the amplitude of the liquid level oscillation of the reagent.

[0032] It should be noted that there are four implementation manners for the first baffle 20 to extend obliquely from the first side wall 12 towards the second side wall 13 and the second baffle 30 to extend obliquely from the second side wall 13 towards the first side wall 12: One of the implementation manners is that in the direction from the first side wall 12 towards the second side wall 13, the distance between the first baffle 20 and the third side wall 14 gradually increases, and in the direction from the second side wall 13 towards the first side wall 12, the distance between the second baffle 30 and the third side wall 14 gradually increases, as shown in Figure 1 ... Another implementation manner is that in the direction from the first side wall 12 towards the second side wall 13, the distance between the first baffle 20 and the third side wall 14 gradually decreases, and in the direction from the second side wall 13 towards the first side wall 12, the distance between the second baffle 30 and the third side wall 14 gradually decreases, as shown in Figure 5 ... Another implementation manner is that in the direction from the first side wall 12 towards the second side wall 13, the distance between the first baffle 20 and the third side wall 14 gradually increases, and in the direction from the second side wall 13 towards the first side wall 12, the distance between the second baffle 30 and the third side wall 14 gradually decreases, as shown in Figure 6 ... Another implementation manner is that in the direction from the first side wall 12 towards the second side wall 13, the distance between the first baffle 20 and the third side wall 14 gradually decreases, and in the direction from the second side wall 13 towards the first side wall 12, the distance between the second baffle 30 and the third side wall 14 gradually increases, as shown in Figure 7 ...

[0033] Of course, it is not limited to the above implementation manner where the first baffle 20 is obliquely arranged with the first side wall 12 and the second baffle 30 is obliquely arranged with the second side wall 13. For example, in some other embodiments, it is also possible to set the first baffle 20 to be perpendicular to the first side wall 12 and the second baffle 30 to be perpendicular to the second side wall 13, which can be determined according to the actual design requirements.

[0034] In one embodiment, the first baffle 20 and the second baffle 30 are straight plates. Straight plates are easy to form, which can reduce the forming difficulty of the reagent container 100 to improve production efficiency. Of course, the first baffle 20 and the second baffle 30 are not limited to being straight plates. For example, in another embodiment, the first baffle 20 and the second baffle 30 are arc-shaped plates that are recessed toward the third side wall 14 or the fourth side wall 15. It should be noted that there are four implementation manners for the first baffle 20 and the second baffle 30 to be arc-shaped plates: One implementation manner is that both the first baffle 20 and the second baffle 30 are recessed toward the third side wall 14, as shown in Figure 8 . Another implementation manner is that both the first baffle 20 and the second baffle 30 are recessed toward the fourth side wall 15, as shown in Figure 9 . Another implementation manner is that the first baffle 20 is recessed toward the third side wall 14 and the second baffle 30 is recessed toward the fourth side wall 15, as shown in Figure 10 . Another implementation manner is that the first baffle 20 is recessed toward the fourth side wall 15 and the second baffle 30 is recessed toward the third side wall 14, as shown in Figure 11 .

[0035] As Figure 1 shown, in one embodiment, the first baffle 20 and the second baffle 30 are arranged at an angle.

[0036] As Figure 1 and Figure 2 shown, in one embodiment, a part of the first bottom wall 11 is recessed toward the third direction Z to form a liquid collecting cavity 17 communicating with the first reagent cavity 16. The third direction Z is perpendicular to the first direction X and the second direction Y. The remaining first bottom wall 11 extends obliquely from the first side wall 12, the second side wall 13, the third side wall 14, and the fourth side wall 15 toward the liquid collecting cavity 17, so that the residual reagent in the first reagent cavity 16 can be collected into the liquid collecting cavity 17. The first baffle 20 extends obliquely from the first side wall 12 gradually toward the liquid collecting cavity 17, and the second baffle 30 extends obliquely from the second side wall 13 gradually toward the liquid collecting cavity 17. When the reagent dispensing mechanism sucks the reagent from the reagent container 100, the reagent needle of the reagent dispensing mechanism penetrates into the liquid collecting cavity 17 to suck the reagent. In this implementation manner, first, by providing the liquid collecting cavity 17 to collect the reagent in the first reagent cavity 16, the residual reagent can be effectively reduced, avoiding unnecessary waste. Second, by providing the first baffle 20 extending obliquely from the first side wall 12 gradually toward the liquid collecting cavity 17 and the second baffle 30 extending obliquely from the second side wall 13 gradually toward the liquid collecting cavity 17, it is beneficial for the reagent to flow into the liquid collecting cavity 17, avoiding waste of the reagent caused by the reagent getting stuck at the first baffle 20 and the second baffle 30. Optionally, the liquid collecting cavity 17 is provided in the middle of the first bottom wall 11.

[0037] Optionally, the liquid collection cavity 17 is located in the middle of the first bottom wall 11. Of course, the liquid collection cavity 17 is not limited to being arranged in the middle of the first bottom wall 11, and it is also possible to arrange the liquid collection cavity 17 at other positions on the first bottom wall 11, which can be specifically determined according to actual design requirements.

[0038] As Figure 2 shown, in one embodiment, the reagent container 100 further includes a support portion 40. The support portion 40 is provided at the bottom of the container body 10 and forms a support plane to provide planar support for the reagent container 100. The height of the support portion 40 in the third direction Z is greater than the height of the liquid collection cavity 17 in the third direction Z.

[0039] As Figure 1 and Figure 2 shown, in one embodiment, the first baffle 20 and the second baffle 30 are combined to form a baffle assembly. The number of baffle assemblies is two, and the two baffle assemblies are spaced apart in the second direction Y. The liquid collection cavity 17 is located between the two baffle assemblies. Of course, the number of baffle assemblies is not limited to two, and it can also be one, three or more, which can be specifically determined according to actual design requirements.

[0040] It should be noted that it is not limited to the above embodiments. For example, in another embodiment, the number of one of the first baffle 20 and the second baffle 30 is N, and the number of the other is N + 1, where N is an integer. That is, in this embodiment, the total number of the first baffle 20 and the second baffle 30 is odd.

[0041] As Figure 2 shown, in one embodiment, the first baffle 20 and the second baffle 30 extend from the first bottom wall 11 towards the opening and do not extend to the edge of the opening.

[0042] In one embodiment, the thickness of the first baffle 20 is less than the thickness of the first side wall 122, and the thickness of the second baffle 30 is less than the thickness of the second side wall 13.

[0043] As Figure 1 and Figure 2 shown, in one embodiment, the container body 10 further includes a second bottom wall 101 and a fifth side wall 102. The fifth side wall 102 is opposite to and spaced apart from the third side wall 14 and is connected to the first side wall 12 and the second side wall 13. The second bottom wall 101, the first side wall 12, the second side wall 13, the third side wall 14 and the fifth side wall 102 form a second reagent cavity 103 with an opening.

[0044] As Figure 1 and Figure 2As shown, in one embodiment, the container body 10 further includes a third bottom wall 104 and a sixth side wall 105. The sixth side wall 105 is opposite to and spaced from the fourth side wall 15 and is connected to the first side wall 12 and the second side wall 13. The third bottom wall 104, the first side wall 12, the second side wall 13, the fourth side wall 15, and the sixth side wall 105 form a third reagent chamber 106 having an opening.

[0045] As Figure 2 shown, in one embodiment, the second bottom wall 101 is also provided with a liquid collecting chamber 17 communicating with the second reagent chamber 103, and the third bottom wall 104 is also provided with a liquid collecting chamber 17 communicating with the third reagent chamber 106.

[0046] In one embodiment, the reagent container 100 further includes a cover plate (not shown in the figure). The cover plate is connected to the container body 10 and is used to seal the openings of the first reagent chamber 16, the second reagent chamber 103, and the third reagent chamber 106. Optionally, the cover plate and the container body 10 are respectively injection-molded from a hard plastic material, and the connection between the cover plate and the container body 10 is achieved by ultrasonic welding.

[0047] As Figure 1 and Figure 2 shown, in one embodiment, the container body 10 is further provided with a receiving hole 107 penetrating the container body 10 along the third direction Z. The third direction Z is perpendicular to the first direction X and the second direction Y. The reagent container 100 further includes a magnetic bead bottle (not shown in the figure), and the magnetic bead bottle is rotatably disposed in the receiving hole 107 relative to the container body 10.

[0048] In one embodiment, the reagent container 100 is a long strip structure extending along the first direction X. Of course, it is not limited to the long strip structure and can also be other structures, which can be specifically determined according to actual design requirements.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
