Description

Technical Field

[0001] This application relates to the field of biological monitoring device technology, and more specifically to a bracket for storing card clips. Background Technology

[0002] Nucleic acid analysis gel columns (or clips) are the core components of fully automated DNA / RNA analysis systems. They are mainly used for automated analysis of samples with high sensitivity and high resolution of macromolecules such as DNA or RNA. They are widely used in fields such as genetic research, disease screening, DNA fingerprinting analysis, and pathogen monitoring.

[0003] The manufacturing process of card clips includes incoming material cleaning, mid-bottom bracket assembly, capillary tube inspection, pressure cleaning, and testing. During this process, temporary storage and transportation of the card clips are required. For storage card clips, the ends of the capillary tubes mounted on the clips need to be kept moist to maintain performance. For transportation card clips, the clips need to be protected from shaking, tilting, or tipping, otherwise it will directly affect the card clip production efficiency and product yield. Currently, there are no dedicated tools for card clip storage and transportation; therefore, there is an urgent need to develop a tool that can simultaneously meet the requirements of capillary tube end insulation and stable transportation. Utility Model Content

[0004] This application provides a tray for storing card clips, which solves the problem that there are currently no tools for storing and transporting card clips.

[0005] To address the aforementioned technical problems, this application provides a holder for storing card clips, comprising a base, a first support member, and a second support member. The base has a support surface with a groove for accommodating a buffer solution. The first support member is disposed on the support surface, and a first slot is provided on its top surface away from the support surface. The second support member is disposed on the support surface, and is spaced apart from the first support member along a first direction. A second slot is provided on the top surface of the second support member away from the support surface. The groove is located between the first and second support members in the first direction. The first slot engages with a first protrusion on the first sidewall of the card clip, and the second slot engages with a second protrusion on the second sidewall of the card clip, allowing the first and second support members to suspend the card clip between them. The groove accommodates a capillary tip on the card clip, allowing the capillary tip to be immersed in the buffer solution.

[0006] In one embodiment, a first support portion is provided on the side of the first support member facing the second support member, and a second support portion is provided on the side of the second support member facing the first support member; both the first support portion and the second support portion are spaced apart from the support surface; the first support portion and the second support portion are used to support the bottom surface of the clip.

[0007] In one embodiment, a first slot extends through a first support member along a first direction, and a second slot extends through a second support member along a second direction.

[0008] In one embodiment, the openings of both the first and second card slots face upwards, and the height directions of both the first and second card slots are parallel to the direction perpendicular to the supporting surface.

[0009] In one embodiment, the length direction of the groove is parallel to the first direction.

[0010] In one embodiment, the first support member includes a first support plate and a first extension plate connected to each other. The first extension plate is disposed on the support surface, and the thickness direction of the first extension plate is perpendicular to the support surface. The thickness direction of the first support plate is perpendicular to the thickness direction of the first extension plate. A first slot is disposed on the top surface of the first support plate.

[0011] The second support member includes a second support plate and a second extension plate connected together. The second extension plate is disposed on the support surface, and the thickness direction of the second extension plate is perpendicular to the support surface. The thickness direction of the second support plate is parallel to the thickness direction of the first support plate. A second slot is disposed on the top surface of the second support plate. The first extension plate is located on the side of the first support plate away from the second support plate, and the second extension plate is located on the side of the second support plate away from the first support plate.

[0012] In one embodiment, the first support member includes a first reinforcing plate, which is connected to the side of the first support plate opposite to the second support plate, and is also connected to the side of the first extension plate opposite to the support surface; the second support member includes a second reinforcing plate, which is connected to the side of the second support plate opposite to the first support plate, and is also connected to the side of the second extension plate opposite to the support surface.

[0013] In one embodiment, the first support member is integrally formed, and the second support member is integrally formed.

[0014] In one embodiment, the first support member is detachably connected to the base, and the second support member is detachably connected to the base.

[0015] In one embodiment, there are at least two first slots, two second slots, and two recesses. Each first slot is spaced apart along a second direction, each second slot is spaced apart along a second direction, and each recess is spaced apart along a second direction. Each recess is located between the first and second slots that are in opposite positions. The second direction is perpendicular to the first direction, and both the second direction and the first direction are perpendicular to the direction perpendicular to the support surface.

[0016] The holder for storing card clips is designed with a first slot on a first support and a second slot on a second support. The first and second slots can engage with protrusions on the two side walls of the card clip, respectively, to ensure that the card clip can be stably suspended between the first and second supports. The engagement of the protrusions and slots prevents the card clip from tilting or tipping over during transport. Furthermore, by providing a groove on the support surface of the base between the first and second supports, the capillary tip on the card clip can be precisely immersed in the buffer solution within the groove when the card clip is suspended between the first and second supports, ensuring that the capillary tip remains moist at all times. By designing this holder for storing card clips, the requirements of keeping the capillary tip moist during storage and ensuring stability during transport can be met. Attached Figure Description

[0025] Please refer to Figure 1-3 This application provides a holder (hereinafter referred to as a holder) for storing card clips. The holder includes a base 10, a first support member 20, and a second support member 30. The base 10 has a support surface 11. Generally, the bottom surface of the base 10 is placed on a surface in an environment such as a desktop, and the top surface of the base 10 is the support surface 11 of the base 10. The directions mentioned in this application are all for reference when the holder is in use. Both the support surface 11 and the bottom surface of the base 10 can be flat.

[0026] A groove 111 is provided on the support surface 11, with the groove 111 opening upwards to allow the capillary on the clip 40 to extend into the groove 111 through the opening. The groove 111 is used to hold a buffer solution, and its capacity can be 5 mL to 10 mL. The buffer solution is preferably a wash buffer, whose main components include tris(hydroxymethyl)aminomethane (Tris), phosphate, surfactant, and preservative. In addition, the groove 111 can also be used to hold mineral oil. In use, the buffer solution can be first introduced into the groove 111, and then mineral oil can be poured on top of the buffer solution to cover it. The buffer solution can be used to wet the capillary on the clip 40, and the mineral oil can reduce the evaporation of the buffer solution.

[0027] A first support member 20 is disposed on a support surface 11, and a second support member 30 is disposed on the support surface 11. The second support member 30 and the first support member 20 are disposed opposite to each other at a distance along a first direction X. This "opposite arrangement" can mean that they are directly opposite each other in the first direction X, or it can mean that some structures are opposite each other and some structures are misaligned in the first direction X. For example, in... Figure 1 In this configuration, the first support member 20 and the second support member 30 are positioned opposite each other. The first direction X is parallel to the support surface 11.

[0028] The first support member 20 has a first slot 21 on its top surface away from the support surface 11, and the second support member 30 has a second slot 31 on its top surface away from the support surface 11. Preferably, the first slot 21 and the second slot 31 are arranged opposite to each other along the first direction X. The groove 111 is located between the first support member 20 and the second support member 30 in the first direction X. Preferably, the groove 111 is located between the first slot 21 and the second slot 31 in the first direction X.

[0029] like Figure 2 As shown, the clip 40 has a first sidewall 41 and a second sidewall 42 arranged opposite to each other along its length. The first sidewall 41 has a first protrusion, and the second sidewall 42 has a second protrusion 421. A first slot 21 is used to engage with the first protrusion of the first sidewall 41 of the clip 40, and a second slot 31 is used to engage with the second protrusion 421 of the second sidewall 42 of the clip 40, so that the first support member 20 and the second support member 30 can support the clip 40 from both sides of the clip 40, and the first support member 20 and the second support member 30 can suspend the clip 40 between the first support member 20 and the second support member 30. Here, "suspended" means suspended in the air, that is, after the clip 40 is installed after the first support member 20 and the second support member 30, there is a certain distance between the bottom wall of the clip 40 and the support surface 11. The suspended state of the clip 40 on the bracket can ensure that the capillary tube on the clip 40 will not be bumped.

[0030] The groove 111 is used to accommodate the lowermost capillary tip 43 of the capillary on the clip 40, so that the capillary tip 43 can be immersed in the buffer solution. Generally, after the clip 40 is installed on the first support 20 and the second support 30, the capillary tip 43 and the cathode need to be completely immersed in the buffer solution, and the immersion depth of the capillary is about 5 mm. This condition can be achieved by reasonably designing the depth of the first slot 21 and the second slot 31 and the depth of the groove 111.

[0031] In use, buffer solution and mineral oil are added into the groove 111, with the mineral oil covering the buffer solution. The pre-filled clip 40 is suspended on the bracket, so that the protrusion of the clip 40 and the slot of the bracket are engaged. The capillary end 43 of the cathode exposed at the bottom of the clip 40 is immersed in the buffer solution in the groove 111 for preservation and transportation.

[0032] The holder for storing the card clips has a first slot 21 on the first support member 20 and a second slot 31 on the second support member 30. The first slot 21 and the second slot 31 can respectively engage with the protrusions on the two side walls of the card clip 40, so that the card clip 40 can be stably suspended between the first support member 20 and the second support member 30. The engagement of the protrusions and the slots can prevent the card clip 40 from tilting or tipping over during transportation. Furthermore, by setting a groove 111 on the support surface 11 of the base 10, the groove 111 is located between the first support member 20 and the second support member 30, so that when the card clip 40 is suspended between the first support member 20 and the second support member 30, the capillary end 43 on the card clip 40 can be precisely immersed in the buffer solution in the groove 111, ensuring that the capillary end 43 is always wet. By designing this holder for storing the card clips, the requirements of keeping the capillary end 43 wet during storage and being stable during transportation can be met.

[0033] In one embodiment, such as Figure 1-3 As shown, a first support portion 22 is provided on the side of the first support member 20 facing the second support member 30, and a second support portion 32 is provided on the side of the second support member 30 facing the first support member 20. Both the first support portion 22 and the second support portion 32 are spaced apart from the support surface 11. The first support portion 22 and the second support portion 32 are used to support the bottom surface of the clip 40, that is, the first support portion 22 and the second support portion 32 can raise the clip 40 relative to the support surface 11, so that there is a certain distance between the bottom surface of the clip 40 and the support surface 11, preventing the capillary tube on the clip 40 from being damaged by impact. By reasonably setting the distance between the first support portion 22 and the second support portion 32 and the support surface 11, the capillary end 43 on the clip 40 can be perfectly accommodated in the groove 111 without colliding with the inner wall of the groove 111.

[0034] In one embodiment, the first slot 21 passes through the first support member 20 along the first direction X, and the second slot 31 passes through the second support member 30 along the second direction Y. The through slot avoids the end obstruction problem that may exist in the non-through slot. When the clip 40 is installed, it is less likely to jam or be damaged due to inaccurate positioning, which reduces the difficulty of operation and can maintain high efficiency even in batch installation scenarios.

[0035] In one embodiment, the openings of both the first slot 21 and the second slot 31 face upwards. The height directions of both the first slot 21 and the second slot 31 are parallel to the direction perpendicular to the support surface 11. This allows the protrusion on the clip 40 to enter the slot through the opening and slide vertically into the slot under its own weight when the clip 40 is assembled. Furthermore, both the first slot 21 and the second slot 31 are straight, ensuring that the clip 40 remains perpendicular to the support surface 11 when suspended on the bracket. This vertical orientation stabilizes the position of the capillary end 43 on the clip 40, ensuring that the capillary end 43 falls into the buffer solution in the groove 111. Preferably, the height of the first slot 21 is the same as the height of the second slot 31.

[0036] In one embodiment, the groove 111 can be elongated, with its length direction parallel to the first direction X. Since the clip 40 typically has a row of capillaries along the first direction X, by extending the groove 111 along the first direction X, the capillary ends 43 of the row of capillaries can be accommodated in the groove 111 after the clip 40 is installed on the first support 20 and the second support 30, so as to be immersed in the buffer solution in the groove 111.

[0037] In one embodiment, the first support member 20 includes a first support plate 23 and a first extension plate 24 connected to each other. The first extension plate 24 is disposed on the support surface 11, and the thickness direction of the first extension plate 24 is perpendicular to the support surface 11. The thickness direction of the first support plate 23 is perpendicular to the thickness direction of the first extension plate 24. A first slot 21 is disposed on the top surface of the first support plate 23, and a first support portion 22 is disposed on the side surface of the first support plate 23.

[0038] The second support member 30 includes a second support plate 33 and a second extension plate 34 connected to each other. The second extension plate 34 is disposed on the support surface 11, and the thickness direction of the second extension plate 34 is perpendicular to the support surface 11. The thickness direction of the second support plate 33 is parallel to the thickness direction of the first support plate 23, that is, the second support plate 33 and the first support plate 23 are arranged in parallel. The second slot 31 is disposed on the top surface of the second support plate 33, and the second support portion 32 is disposed on the side surface of the second support plate 33. The first extension plate 24 is located on the side of the first support plate 23 away from the second support plate 33, and the second extension plate 34 is located on the side of the second support plate 33 away from the first support plate 23. Thus, both extension plates have a structure facing away from the support plate, so that the extension plates can provide stable support to the support plate from the side of the support plate away from the clamp 40, thereby strengthening the support capacity of the support plate, preventing the support plate from deforming or bending due to long-term stress, and ensuring the stability of the support plate's support for the clamp 40.

[0039] Furthermore, the first support member 20 includes a first reinforcing plate 25, which is connected to the side of the first support plate 23 opposite to the second support plate 33, and is also connected to the side of the first extension plate 24 opposite to the support surface 11. The second support member 30 includes a second reinforcing plate 35, which is connected to the side of the second support plate 33 opposite to the first support plate 23, and is also connected to the side of the second extension plate 34 opposite to the support surface 11. Thus, the reinforcing plate increases the stress-bearing area at the connection between the support plate and the extension plate, reduces local stress concentration, and achieves a triangular stable structure of support plate-reinforcing plate-extension plate, thereby improving the support member's resistance to bending and deformation. Even under conditions of heavy clamp 40 or long-term transport and vibration, it can prevent breakage or deformation at the connection between the support plate and the extension plate.

[0040] In one embodiment, the first support member 20 and the second support member 30 are integrally formed. The integral forming design can avoid gaps or connection stresses caused by the splicing of parts in a split structure, so that the various plates of the first support member 20 form a seamless integral structure, eliminating the risk of loosening caused by assembly gaps, and also eliminating the need for processing, assembly, calibration and other steps of split parts, reducing production processes and labor costs.

[0041] In one embodiment, the first support member 20 is detachably connected to the base 10, and the second support member 30 is detachably connected to the base 10. The detachable connection can be achieved through methods such as plug-in, snap-fit, magnetic connection, or threaded connection. By detachably connecting the first support member 20, the second support member 30, and the base 10, the bracket can be disassembled and stored when not in use, reducing the stacking space of the support members and the base 10. This is particularly beneficial for space reduction during bulk transportation, thus lowering warehousing and logistics costs.

[0042] In one embodiment, the number of first card slots 21, second card slots 31, and recesses 111 are all at least two. The first card slots 21 are spaced apart along the second direction Y, the second card slots 31 are spaced apart along the second direction Y, and the recesses 111 are spaced apart along the second direction Y. This spacing prevents contact or collision between adjacent card clips 40. Each recess 111 is positioned between opposite first card slots 21 and second card slots 31, meaning each recess 111 corresponds to a set of opposite card slots. This prevents cross-contamination of the capillary ends 43 of different card clips 40 within the same recess 111, ensuring an independent storage environment for each card clip 40. The second direction Y is perpendicular to the first direction X, and both the second direction Y and the first direction X are perpendicular to the direction perpendicular to the support surface 11. Therefore, the bracket can simultaneously store two or more card clips 40. This multi-station design significantly increases the storage capacity per unit space, reduces the number of round trips per operation, and improves production process efficiency.

[0043] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
