Description

Technical Field

[0001] The utility model relates to the pipetting technical field such as biological detection, and particularly relates to a pipetting platform carrier and a pipetting platform. Background Art

[0002] For the biological detection industry, when conducting some experiments with high repeatability, it is a waste of labor and low in efficiency for experimenters or operators to repeat the same operation for a long time. A pipetting platform is an efficient and reliable experimental device, and its main function is to perform operations such as liquid movement and transfer. The pipetting platform can help experimenters quickly, accurately and conveniently complete various experiments. The pipetting platform usually precisely transfers a specific volume of liquid from one container to another to achieve a specific purpose. The existing pipetting platforms in the prior art are usually automatically controlled, which can reduce labor costs and improve pipetting efficiency and accuracy. The carrier is a support body that is matched with the pipetting platform and is used for placing consumables (i.e., containers, such as reagent tubes). However, the carriers of the existing pipetting platforms in the prior art either have few consumables that can be loaded, or are inconvenient for detection when loading more consumables, which may cause cross-contamination and are not convenient for picking and placing, and need to be further improved. Summary of the Utility Model

[0003] The purpose of the utility model is: aiming at the deficiencies in the above background art, to provide a carrier with a large loading capacity, convenient picking and placing, and safe detection without cross-contamination.

[0004] To achieve the above purpose, the utility model provides a pipetting platform carrier, which includes a frame body, a carrier table and consumables. The carrier table is connected to the frame body. The carrier table is provided with a plurality of placement holes for placing the consumables, and the aperture of the placement holes matches the outer diameter of the consumables.

[0005] The consumables include a tube body and a tube cap, and the tube cap is connected to the tube body through a deformable connecting part. A cap support part is arranged on the carrier table.

[0006] The cap support part includes a support seat, a first limiting block and a second limiting block. The first limiting block and the second limiting block are both connected to the support seat. A limiting groove is formed between the first limiting block and the second limiting block. The limiting groove is used for limiting the tube cap after insertion. The limiting groove is provided with a notch, and the notch is used for the connecting part to pass through after the tube cap is inserted into the limiting groove.

[0007] Further, the carrier table and the frame body are integrally provided, or the carrier table and the frame body are detachably connected.

[0008] Further, the placement holes are through holes that penetrate the upper and lower surfaces of the carrier platform. The bottom aperture of the placement holes is reduced and is smaller than the outer diameter of the consumable;

[0009] Alternatively, the placement holes are blind holes.

[0010] Further, the carrier platform has multiple specifications, and the apertures of the placement holes on each carrier platform of each specification are different; alternatively, the apertures of the placement holes on the same carrier platform are set differently.

[0011] Further, an elastic sleeve is arranged in the placement hole. The elastic sleeve is made of an elastic material and is in interference fit with the consumable.

[0012] Further, the placement holes are distributed in a rectangular array on the carrier platform. For each row of placement holes, the second limiting blocks on the support seat are continuously arranged, and the first limiting blocks are intermittently arranged. The gap between two adjacent first limiting blocks forms the notch.

[0013] Further, the cover support parts of two adjacent rows of the placement holes are arranged in opposite directions. The tube cover of the consumable in the nth row of the placement holes is flipped and opened forward, and the tube cover of the consumable in the (n + 1)th row of the placement holes is flipped and opened backward, alternating in turn.

[0014] Further, a constant temperature module is also arranged in the frame body. The constant temperature module is used to keep the reagent on the carrier platform at a constant temperature.

[0015] Further, the constant temperature module is a metal bath module.

[0016] The present utility model also provides a pipetting platform provided with the pipetting platform carrier as described above.

[0017] The above solution of the present utility model has the following beneficial effects:

[0018] The pipetting platform carrier provided by the present utility model can load a considerable number of consumables, and can stably place consumables such as 5 ml reagent tubes and 2 ml EP tubes. It can make full use of the space of the carrier platform in a back-to-back manner. Through the cover support part, the opened tube cover can be stably supported and limited, avoiding cross-contamination caused by the shaking of the tube cover during the operation of the pipetting platform. Therefore, the accuracy and efficiency of pipetting detection of the pipetting platform are improved;

[0019] Other beneficial effects of the present utility model will be described in detail in the subsequent specific implementation part. Description of the Drawings

[0026] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model. In addition, the technical features involved in the different implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] Such asFigure 1 As shown in the figure, an embodiment of the present utility model provides a pipetting platform carrier, which includes a frame body 1 and a stage 2, and also includes consumables. Among them, the stage 2 is placed on the frame body 1, and the frame body 1 is used to support the stage 2. The two can be an integral structure or an independent and detachable structure. The stage 2 is usually set as a square structure, but of course it can also be set as a circular or other shape, and has a certain depth and is provided with placement holes 3 for placing consumables.

[0030] Among them, the placement hole 3 can be set as a through hole, that is, the placement hole 3 penetrates the upper surface and the lower surface of the stage 2, and the bottom aperture of the placement hole 3 is reduced to be smaller than the outer diameter of the consumable, so that the consumable can be inserted into the placement hole 3 but will not fall from the bottom of the placement hole 3. Of course, the placement hole 3 can also be set as a blind hole that does not penetrate the lower surface of the stage 2, and the consumable can be supported by the bottom of the placement hole 3 after being inserted.

[0031] It should be noted that common consumables include forms such as 5 ml reagent tubes 4, 2 ml EP tubes 5, etc. Among them, the 5 ml reagent tube 4 has a relatively large capacity and is mainly used for loading various biological reagents or other solutions. The EP tube 5 is a small centrifuge tube, also known as a microcentrifuge tube, and is mainly used for the separation of trace reagents. Therefore, there is also a need to transfer the reagents in the EP tube 5. Based on this, in this embodiment, the aperture of the orifice and the main body part of the placement hole 3 is set to match the reagent tube 4, or match the EP tube 5, or adopt a mixed form, that is, the placement hole 3 on one side of the stage 2 is adapted to the reagent tube 4, and the placement hole 3 on the other side of the stage 2 is adapted to the EP tube 5, as Figure 2 shown. Of course, it can also be adapted to other types and different sizes of consumables. This multi-specification setting of the stage 2 improves the flexibility of the pipetting platform.

[0032] It should be noted that considering the stability of the consumables placed in the placement hole 3 (including during the placement process), in this embodiment, an elastic sleeve 6 (made of silica gel or other elastic materials) is further arranged in the placement hole 3. The elastic sleeve 6 forms an interference fit with the consumable to provide resistance during the taking and placing of the consumable for convenient placement, as Figure 3 shown.

[0033] Among them, consumables such as reagent tubes 4 and EP tubes 5 all have tube caps 7, and the tube caps 7 are connected to the tube bodies 8 through deformable connecting parts. During the operation of the pipetting platform, the tube caps 7 need to be maintained in an open state to facilitate the operation of the pipette tips. However, the connection method between the tube caps 7 and the tube bodies 8 using connecting parts may have instability problems, resulting in contact between the residual reagents on the tube caps 7 and the reagents in other positions, causing cross-contamination. Based on this, in this embodiment, a cap support part is further provided on the carrier 2, and the cap support part is used to support and limit the tube caps 7 of the reagent tubes 4, EP tubes 5 or other consumables, so as to prevent the tube caps 7 from shaking or interfering with the pipette tips during the operation of the pipetting platform after being opened.

[0034] Specifically, the cap support part includes a support base 9 and a first limit block 10 and a second limit block 11 provided on the support base 9. Preferably, the first limit block 10, the second limit block 11 and the support base 9 are integrally formed structures, the first limit block 10 and the second limit block 11 are arranged in parallel, and the gap therebetween forms a limit groove for limiting the tube cap 7. At the same time, the limit groove has a notch at the position of the first limit block 10, and the notch is used for the connecting part between the tube cap 7 and the tube body 8 to pass through. Therefore, when the tube body 8 is inserted into the placement hole 3, the tube cap 7 can be opened and rotated until it is inserted into the limit groove, and the tube cap 7 can be stably maintained in an open state through the limitation of the limit groove.

[0035] As a preferred implementation manner, in this embodiment, the placement holes 3 on the carrier 2 are arranged in a rectangular array, that is, multiple rows and multiple columns are set to make the best use of the space of the carrier 2 as much as possible. Correspondingly, for each row of placement holes 3, the second limit blocks 11 on the support base 9 can be continuously arranged, and the first limit blocks 10 can be intermittently arranged, so that the gap between two adjacent first limit blocks 10 forms a notch.

[0036] In a further improvement scheme of this embodiment, the cap support parts of two adjacent rows of placement holes 3 are arranged in the opposite direction, that is, the tube caps 7 of the consumables in the nth row of placement holes 3 are flipped forward to open, and the tube caps 7 of the consumables in the (n + 1)th row of placement holes 3 are flipped backward to open, and so on alternately, forming a back-to-back layout form. By adopting this method, the operation space between the nth row and the (n - 1)th row, and the (n + 1)th row and the (n + 2)th row can be significantly increased, which is beneficial to the operation of the pipette tips. Wherein, n is an integer and n≥2. In addition, it should be noted that this setting method enables two adjacent cap support parts to share the support base 9 and the second limit block 11 to further reduce the occupied space.

[0037] As a preferred implementation manner, in this embodiment, the carrier 2 and the frame 1 are detachably connected, and the bottom contour of the carrier 2 adopts a unified specification, so that only one type of frame 1 can be manufactured, avoiding the tediousness of preparing multiple types of frames 1. At the same time, as Figure 4As shown, a metal bath module 12 can also be provided inside the frame body 1. The metal bath module 12 is a constant temperature module that uses high-purity aluminum material as a heat conduction medium to replace the traditional medium. It has the characteristics of convenient use, large temperature control range, high precision, etc. Therefore, it can keep the reagents on the stage 2 at a constant temperature.

[0038] In summary, by using the pipetting platform carrier provided in this embodiment, a considerable number of consumables can be loaded, which is adapted to the pipetting platform. Moreover, consumables such as 5 ml reagent tubes 4 and 2 ml EP tubes 5 can be stably placed. The space of the stage 2 can be fully utilized in a back-to-back manner. At the same time, the opened tube cap 7 can be firmly supported and limited by the cap support part, avoiding cross-contamination caused by the shaking of the tube cap 7 during the operation of the pipetting platform, and improving the accuracy and efficiency of pipetting and detection of the pipetting platform.

[0039] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0040] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
