Description

Technical Field

[0001] The present application relates to a supporting device, in particular to a Pasteurized straw rack. Background Art

[0002] Pasteur pipettes, also known as Pasteur pipettes or transfer pipettes, are often made of polymer materials such as polyethylene (PE). They feature a hollow sac within a translucent tube; this sac facilitates mixing of solvents and cells. The tubes offer ideal fluidity and controllability, and are slender, flexible, and flexible, making them convenient for transferring liquids into and out of micro-volumes or specialized containers. The heat-sealable ends facilitate easy portability. Pasteur pipettes are miniature tools commonly used in medical and biological experiments to remove small amounts of liquid from test tubes or containers, particularly in cell culture and histological analysis.

[0003] At present, relevant patents have disclosed some devices for supporting Pasteur pipettes. For example, patent document CN205253171U discloses a Pasteur pipette rack, including a test tube rack body with a triangular prism structure, and through holes are provided on its three side edges, which is used to solve the shortcomings of Pasteur pipettes easily contaminating the operating table and being unstable when used. For another example, patent document CN209205348U discloses a Pasteur pipette placement rack, including a crossbeam, a groove, a triangular bracket, a card slot, a liquid collection tank, and an anti-slip pad. The crossbeam is provided with two or more grooves, and the two sides of the crossbeam are respectively provided above the triangular bracket, and the triangular bracket is provided with a card slot below. The two card slots are movably provided with a liquid collection tank, and the bottom of the triangular bracket is provided with an anti-slip pad; when in use, the Pasteur pipette is placed firmly, not easy to tip over, and can prevent liquid dripping.

[0004] The above-mentioned Pasteur pipette racks primarily store Pasteur pipettes in a horizontal or diagonal position. This method, due to the overall slender structure of Pasteur pipettes, is best practiced to store them in a single horizontal position, as the upper layers of the rack would obstruct access to the lower layers if multiple layers were placed. This, when many pipettes are used simultaneously, inevitably takes up a significant amount of space on the workbench, hindering access to other laboratory equipment. Therefore, a Pasteur pipette rack is needed that can replace the horizontal arrangement and stably support multiple Pasteur pipettes while minimizing space consumption. Utility Model Content

[0005] As a main technical solution, the present application provides a Pasteurized straw rack, comprising a rack body having a surface with holes arranged on the top thereof; the holes are downwardly opened for accommodating Pasteurized straws in an inserted manner, and have an accommodating depth that is less than the length of the Pasteurized straws.

[0006] In one or more embodiments, the tube holder body comprises a first flat surface defining the hole, and a second flat surface disposed below the first flat surface for supporting the Pasteur pipette. Furthermore, the tube holder body is a box having a hollow interior, wherein the top and bottom of the box are flat surfaces, respectively forming the first and second planes. Alternatively, the tube holder body comprises a plurality of upright supports and two flat plates fixedly connected to the plurality of supports, the two flat plates being disposed in two layers, respectively forming the first and second planes.

[0007] In this way, when the Pasteurized straw rack is in use, multiple Pasteurized straws can be placed vertically on the rack body, and a large number of straws can be stably carried at the same time, which reduces space occupation. Moreover, the direction of taking and placing the straws is consistent or roughly consistent with the length direction of the straws. There will be no obvious obstruction between the straws during the taking and placing process, which is conducive to the convenient use of the straws.

[0008] As an auxiliary technical solution, the Pasteurized straw rack provided in this application also includes a protective sleeve, which is cylindrical with an open upper end and a sealed lower end, and can be removably inserted into the hole, and is used to at least cover the lower part of the Pasteurized straw when the tube rack body accommodates the Pasteurized straw.

[0009] In one or more embodiments, the sheath is tapered with a smaller bottom and a larger top.

[0010] In one or more embodiments, the upper sidewall of the sheath may be provided with a first convex ring, the outer diameter of which is larger than the diameter of the hole. Further, the upper sidewall of the sheath may be provided with a second convex ring, the second convex ring being located above the first convex ring.

[0011] Thus, by using the above-mentioned sheath, the Pasteur pipettes can be isolated from each other and placed more stably on the pipette holder body. Moreover, when inserting or removing the Pasteur pipettes, the ends of the pipettes can be prevented from touching the pipette holder body and other pipettes, thereby avoiding contamination.

[0019] The present application will be described in detail below with reference to the exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concepts of the present application to those skilled in the art.

[0020] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and 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, be constructed and operated in a specific orientation. Therefore, it should not be understood as limiting the scope of protection of this application.

[0021] Also refer to Figures 1 to 4 In some embodiments of the present application, a Pasteurized straw rack includes a rack body 10 and a protective sleeve 20. The top of the rack body 10 has a surface with a hole 11 disposed thereon. The hole 11 is downwardly extending for inserting and accommodating a Pasteurized straw 30 and has a depth that is less than the length of the Pasteurized straw 30. More specifically, the rack body 10 has a first flat surface 12 defining the hole 11, and a second flat surface 13 disposed below the first flat surface 12 for supporting the Pasteurized straw 30. The protective sleeve 20 is cylindrical, with an open top and a sealed bottom. It is removably inserted into the hole 11 and is positioned over the lower portion of the Pasteurized straw 30 when the rack body 10 accommodates the Pasteurized straw 30. The length of the sheath 20 can be shorter or longer than the length of the Pasteurized straw 30. When the sheath 20 is shorter than the length of the Pasteurized straw 30, especially shorter than the length of its slender tube, the hollow sac at the upper end of the Pasteurized straw 30 can be exposed, making it easier to observe. When the sheath 20 is longer than the length of the Pasteurized straw 30, it is more convenient to take the Pasteurized straw 30 and put it away together with the sheath 20.

[0022] As one example, refer to Figure 1 and Figure 3 The pipe rack body 10 comprises several upright supports 14 and two flat plates fixedly connected to the supports 14. The two flat plates are arranged in two layers, forming a first flat surface 12 and a second flat surface 13, respectively. Furthermore, an annular groove 15 is provided on the second flat surface 13, opposite the hole 11, for receiving the lower end of the sheath 20. The supports 14 can adopt the structure shown in the figure, namely, they are in the shape of a closed, elongated ring, with their upper ends protruding upward from the upper flat plate to form a handle, and their lower ends protruding downward from the lower flat plate to form a support leg.

[0023] As another example, refer to Figure 2 and Figure 4 The pipe rack body 10 is a box with a hollow interior. The top and bottom of the box are both flat, forming a first plane 12 and a second plane 13, respectively. The box is a square box that can be opened from the sidewalls to facilitate cleaning. The bottom of the hollow box can be provided with an annular groove 15, but due to the function of the sheath 20, its absence (as shown in the figure) does not affect normal use.

[0024] refer to Figure 5 The figure shows various optional structures of the sheath 20. The first is sheath a in the figure, which is a conventional long cylindrical shape. The outer wall of the lower end does not shrink or does not shrink too much, but the inner diameter of the bottom of the sheath 20 continuously decreases downward to adapt to the shape of the Pasteur pipette 30. The second is sheath b in the figure, which has a first protruding ring 21 on its upper side wall. The outer diameter of the first protruding ring 21 is larger than the aperture 11; the first protruding ring 21 is used to limit the position and stably support the top of the pipe holder body 10. The third is sheath c in the figure, which has both a first protruding ring 21 and a second protruding ring 22. The second protruding ring 22 is located above the first protruding ring 21 and is mainly used to facilitate the removal of the sheath. Fourth, as shown in the figure, sheath d is conical in shape, with a small bottom and a large top. Since the diameter of the Pasteur pipette is extremely small (about 1 to 7 mm), it is inconvenient to pick it up directly with hands. Therefore, compared with the structures of the first three, when the conical structure of sheath d is selected, the volume of its upper part can be greatly increased, making it more convenient to take it in and out, thereby improving the efficiency of liquid collection.

[0025] The sheath 20 can be disposable or reusable, but requires thorough cleaning before reuse. When removing or removing the Pasteurized pipette 30, it is best to place the sheath 20 and the Pasteurized pipette 30 together in the rack body 10 to prevent the Pasteurized pipette 30 from contacting other nearby pipettes. Furthermore, the sheath 20 can be given different colors for easy sorting and identification. Furthermore, the material used for the sheath 20 is preferably autoclavable to facilitate its application in sterile culture and other fields, thereby broadening its scope of application.

[0026] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of this application should be within the scope of protection of this application.
