Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic microparticle chemiluminescence technology, and in particular to a magnetic microparticle chemiluminescence reagent kit. Background Technology
[0002] Currently, magnetic particle chemiluminescence is a fully automated process, so the reagent rack must be compatible with the instrument. This results in the reagent rack's size and specifications being basically fixed, especially when used with reagent kits (such as...). Figure 1 The space occupied within the reagent rack (as shown) is basically fixed. Besides the reagent rack, the kit also contains an inner liner for holding reagent tubes of other components. This inner liner is embedded in the kit and adjacent to the reagent rack. The inner liner is typically a single layer, with a thickness much smaller than the height of the reagent rack. The reagent rack only contacts the inner liner within its thickness range, leaving the space above the inner liner adjacent to the reagent rack empty. This is detrimental to the stability of the reagent rack within the kit and also hinders the full utilization of the internal space, resulting in a large overall kit volume with a lot of empty space. This not only increases manufacturing costs but also poses challenges in terms of storage and transportation costs. Furthermore, the inner liner cannot be too small, as this would result in insufficient reagent well positions to accommodate all reagent tubes. Therefore, it is essential to design a kit that does not reduce the number of reagent well positions while effectively improving reagent rack stability and reducing kit manufacturing and transportation costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a magnetic microparticle chemiluminescence reagent kit, which has high internal reagent rack stability and full space utilization. Without reducing the number of reagent wells, the overall volume of the reagent kit is reduced, thereby reducing the reagent kit manufacturing cost, transportation cost and storage space.
[0004] To solve the above-mentioned technical problems, the present invention provides a magnetic microparticle chemiluminescence reagent kit, comprising:
[0005] The box has a lid on top;
[0006] A reagent rack, which is disposed within the box;
[0007] The lower inner liner is placed on the inner bottom surface of the box body and adjacent to the reagent rack. The lower inner liner has reagent holes for accommodating reagent tubes.
[0008] An upper inner liner is placed inside the box adjacent to the reagent rack and located on the top surface of the lower inner liner. The upper inner liner has reagent holes for accommodating reagent tubes.
[0009] The combined thickness of the upper and lower inner liners is at least 2 / 3 of the height of the reagent rack.
[0010] Preferably, the reagent holder, the lower inner liner, and the upper inner liner fill the inner cavity of the box.
[0011] Preferably, the inner cavity of the box is a cuboid;
[0012] The reagent rack has a cross-section that is a right trapezoid.
[0013] The upper inner liner and the lower inner liner have the same cross-section, both being right-angled trapezoids, and match the cross-section of the reagent rack.
[0014] Preferably, the sidewalls of the lower inner liner and the upper inner liner on the side away from the reagent rack are connected at the edge position to form a joint edge, and can be folded relative to the joint edge.
[0015] Preferably, the lower inner liner has four reagent wells.
[0016] Preferably, the reagent holes of the lower inner liner are arranged along its waist at right angles.
[0017] Preferably, the upper inner liner has four reagent wells.
[0018] Preferably, the reagent holes of the upper inner liner are arranged along its waist at right angles.
[0019] The magnetic microparticle chemiluminescence reagent kit provided by this invention increases the contact area of the reagent rack in the height direction by setting the inner liner as an upper inner liner and a lower inner liner stacked one on top of the other, thereby increasing the stability of the reagent rack in the reagent kit and improving the space utilization of the reagent kit. In addition, the reagent well positions are evenly distributed on the upper inner liner and the lower inner liner, which can reduce the area of the upper inner liner and the area required to accommodate the reagent tubes. The overall volume of the reagent kit of this invention is significantly reduced, thereby reducing manufacturing costs and space occupancy during transportation and storage, thus reducing transportation and storage costs.

[0025] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] refer to Figure 2 and Figure 3 This invention discloses a magnetic microparticle chemiluminescence reagent kit, comprising:
[0027] The box has a lid on top;
[0028] A reagent rack, which is disposed within the box;
[0029] The lower inner liner is placed on the inner bottom surface of the box body and adjacent to the reagent rack. The lower inner liner has reagent holes for accommodating reagent tubes.
[0030] An upper inner liner is placed inside the box adjacent to the reagent rack and located on the top surface of the lower inner liner. The upper inner liner has reagent holes for accommodating reagent tubes.
[0031] The combined thickness of the upper and lower inner liners is at least 2 / 3 of the height of the reagent rack.
[0032] In this embodiment of the invention, the single-layer inner liner is improved by placing an upper inner liner and a lower inner liner together in an overlapping manner. After overlapping, the contact area with the reagent rack in the height direction is increased, ensuring the stability of the reagent rack within the reagent kit and increasing the utilization rate of the internal space of the reagent kit. After stacking, the sum of the thicknesses of the upper and lower inner liners is preferably 2 / 3 of the height of the reagent rack to maintain the stability of the reagent rack. For example, if it is less than 2 / 3, the stability of the reagent rack within the kit will be affected. In addition, the reagent well positions are preferably evenly distributed on the upper and lower inner liners. Compared with the single-layer inner liner design, the cross-sectional area of the inner liner (including the upper and lower inner liners) can be effectively reduced, thereby reducing the volume of the reagent kit and lowering the manufacturing cost. At the same time, the smaller reagent kit body reduces its footprint, which in turn reduces transportation and storage costs to a certain extent.
[0033] In one specific embodiment, the reagent rack, the lower inner liner, and the upper inner liner completely fill the inner cavity of the box. Preferably, the inner cavity of the box is a cuboid, the cross-section of the reagent rack is a right-angled trapezoid, and the cross-sections of the upper inner liner and the lower inner liner are the same, both being right-angled trapezoids, and matching the cross-section of the reagent rack. It should be noted that "completely fills" in this specific embodiment means that after the lower inner liner, the upper inner liner, and the reagent rack are assembled into the box, they form a structure with at least the same (or substantially the same) circumferential dimension as the box, allowing them to contact the inner wall of the box. The inner wall limits the lower inner liner, the upper inner liner, and the reagent rack, ensuring their stability. At the same time, the thickness of the upper and lower inner liners after stacking is comparable to the height of the reagent rack, so that after being transferred into the box, there is no large volume of empty space inside the box.
[0034] In this specific embodiment, after the reagent rack, upper inner liner, and lower inner liner are assembled, they form a cuboid that is substantially equal to the internal space of the reagent kit, thereby improving the space utilization of the reagent kit; wherein, the lower inner liner is in contact with or joined to the inner bottom surface of the reagent kit.
[0035] In one specific embodiment, the sidewalls of the lower inner liner and the upper inner liner on the side away from the reagent rack are connected at an edge position to form a joining edge, and can be folded relative to the joining edge; understandably, when the upper inner liner and the lower inner liner are unfolded relative to the joining edge, they form an isosceles trapezoid with a cross-section such as... Figure 2 As shown. It should be noted that the joining edges can also be the edges of the sidewalls corresponding to the upper or lower base of a right trapezoid, and the connection can be formed, for example, by incomplete cutting during processing. If you do not wish to be constrained by this, the lower inner liner and the upper inner liner can also be set independently, with no connection between them. Since their shapes are exactly the same, it is easier to process.
[0036] In one specific embodiment, the lower inner liner has four reagent holes arranged at right angles along its sides; the upper inner liner also has four reagent holes arranged at right angles along its sides. Alternatively, the reagent holes can be arranged along the sidewall in contact with the reagent holder.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
