Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of medical detection experimental devices, and in particular, relates to a multi-tube detachment device. Background Art
[0002] An octa-tube strip refers to a tubular device that can process multiple samples simultaneously in a polymerase chain reaction (PCR), usually containing eight independent reaction wells or channels. The octa-tube strip is used as a reaction container, and this design enables researchers to amplify multiple target sequences simultaneously in one experiment, improving experimental efficiency and accuracy. In biological research, especially in the fields of molecular biology, genetics, and medicine, the octa-tube strip has been widely used. In addition to the octa-tube strip, there are other specifications of strips, such as two-strip tubes, four-strip tubes, six-strip tubes, etc. The design principles of these strips are similar to those of the octa-tube strip, all of which are designed to process multiple samples or target sequences simultaneously in one experiment.
[0003] During the operation, the eight-tube strips need to be placed in the eight-tube rack, and then reagents and processed specimens are added to the eight-tube strips, and then the strips are capped, mixed, and placed in the amplification instrument for reaction detection, and finally the eight-tube strips are discarded. The eight-tube strips must be tightly capped when in use. This is because the eight-tube strips need to be placed in the amplification instrument to undergo repeated high-temperature heating and annealing at about 93°C and 65°C. If the tube caps are not fully capped, they are very easy to burst during the amplification process, and the amplification products will leak out. Not only will the experimental results be inaccurate, but it will also cause laboratory contamination, seriously affecting the subsequent testing work of the laboratory, and the steps for cleaning the contamination of the amplification products are very cumbersome and difficult to completely remove. Therefore, the seemingly simple eight-tube strip capping is an especially important step in the entire operation process. The existing eight-tube strip capping method is to place the eight-tube strip on the rack, and use downward pressure to press the lid and the eight-tube strip tightly, but after applying force to cap, the eight-tube strip will be tightly clamped in the eight-tube rack, making it difficult to take out.
[0004] The existing technology does not have a tool or device that can easily pull out the eight-tube strip from the rack. At present, the eight-tube strip is directly pulled out by manpower during the experiment. However, if the eight-tube strip is pulled out by force, it is easy to dirty the tube cover, affecting the instrument scanning reading, and the tube cover will become loose, resulting in inaccurate results or laboratory contamination. On the other hand, the force when pulling out the eight-tube strip is difficult to control, and the operation cannot be managed in a homogeneous manner. Each operation has different degrees of risk. The same problem exists for multi-tube strips, and a simple device that can be applied to actual operations is urgently needed. Utility Model Content
[0005] The present application aims to solve the technical problem of pulling out multi-tubes from the rack at least to a certain extent. To this end, the present application provides a multi-tube detachment device that can assist in homogenization operations and facilitate the detachment of multi-tubes from the rack. The detached multi-tubes can meet uniform standards and avoid problems such as contamination of tube covers and loose tube covers.
[0006] The embodiment of the present application provides a multiple-tube detaching device, wherein a storage rack is provided with a storage hole for fixing the multiple-tube, and the storage rack comprises:
[0007] A main body, the top of which is used to place a storage rack;
[0008] A plurality of push rods are respectively connected to the main body, the push rods protrude from the top of the main body, and the ends of the push rods exposed from the main body are provided with positioning notches;
[0009] When the storage rack is placed on the top of the main body, the top rod can support the multi-tube placed in the storage rack, and the bottom end of each tube of the multi-tube is positioned in the positioning notch.
[0010] In an optional embodiment, a plurality of push rods are spaced apart and arranged in a line, so that each push rod can correspond to the position of each tube of the multi-tube.
[0011] In an optional embodiment, a plurality of push rods are arranged in an array, and the position of each push rod corresponds to each storage hole of the storage rack.
[0012] In an optional embodiment, the push rod is movable in the axial direction relative to the main body, so that the height of the push rod protruding from the main body can be adjusted.
[0013] In an optional embodiment, a first fixing member is further included, the first fixing member is fixed to the main body, and the push rod is threadedly connected to the first fixing member, so that the push rod can move axially.
[0014] In an optional embodiment, a second fixing member is further included, the second fixing member is fixed to the main body, the second fixing member is spaced apart from the first fixing member, and the bottom end of the top rod is threadedly connected to the second fixing member.
[0015] In an optional embodiment, the push rod is provided with an external thread arranged along the axial direction.
[0016] In an optional embodiment, the first fixing member and the second fixing member are respectively provided with internal threaded holes penetrating the top and bottom, the second fixing member is located inside the main body, and the first fixing member is located on the top of the main body.
[0017] In an optional embodiment, the positioning notch is formed by a recessed end surface of the top rod, and the width of the positioning notch is greater than or equal to the bottom ends of each tube of the multi-tube, so that the bottom ends of each tube of the multi-tube can be inserted into the positioning notch for positioning.
[0018] In an optional embodiment, the size of the main body matches the size of the storage rack, so that when the storage rack is placed on the main body, the edge of the main body can be aligned with the edge of the storage rack.
[0019] It can be seen from the above technical solution that the beneficial effects of this application are:
[0020] The present application no longer needs to pull out the multi-tube from the storage rack, thus eliminating the need for operation. The storage rack is directly placed on the main body, and a slight downward force is applied to the storage rack. Since each tube of the multi-tube is positioned through a positioning groove, the multi-tube can be easily lifted from the storage rack by utilizing the upward force of the push rod, thereby reducing the requirements for operators, assisting in homogenization operations, and facilitating the detachment of the multi-tube from the rack. The detached multi-tube can meet unified standards, and also avoids problems such as contamination of the tube covers and loose tube covers. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0034] Please refer to Figure 1 and Figure 2The embodiment of the present application provides a multi-tube detachment device, the storage rack 300 is provided with storage holes 321 for fixing the multi-tube 200, the multi-tube 200 is a four-tube, a six-tube, an eight-tube, etc., the present application takes the eight-tube as an example for explanation, the storage rack 300 adopts an existing 96-hole rack, a total of 8 rows * 12 columns of storage holes 321, the size of the storage rack 300 is: length 124mm, width 88mm, height 15mm, the spacing between adjacent rows of storage holes 321 can be determined according to the spacing between adjacent tubes in the multi-tube 200, the eight-tube is placed on the storage rack 300 through the storage holes 321, each tube of the eight-tube is clamped in the storage hole 321 at the corresponding position, the storage rack 300 The existing frame structure is adopted, and the storage rack 300 includes a bracket plate 320 and a frame 310. The frame 310 is a frame-like structure arranged in the vertical direction, such as four plate-like structures connected end to end. The bracket plate 320 is plate-shaped, and the periphery of the bracket plate 320 is connected to the inner side of the frame 310, and the bracket plate 320 is perpendicular to the frame 310. The bracket plate 320 is provided with a plurality of storage holes 321, and the storage holes 321 are arranged in an array. There is a gap between the bottom of the bracket plate 320 and the plane where the bottom of the frame 310 is located, so that a cavity is formed under the bracket plate 320. When the eight-tube strip is placed on the storage rack 300, each tube of the eight-tube strip is placed in the storage hole 321, and the bottom end of each tube extends into the cavity.
[0035] Please refer to Figure 3The device 100 includes: a main body 110 and a plurality of push rods 120. The top of the main body 110 is used to place the storage rack 300. The plurality of push rods 120 can be installed on the main body 110. The main body 110 can adopt a rectangular parallelepiped structure. A concave hole for installing the push rod 120 is concavely arranged inwardly at the top of the main body 110, so that the push rod 120 can be connected and fixed with the main body 110 by being fixed in the concave hole; the plurality of push rods 120 are respectively connected to the main body 110, and each push rod 120 is clamped in the concave hole. A threaded connection method can be adopted. For example, the concave hole is an internal threaded hole, and the push rod 120 has an external thread. In this way, after the push rod 120 is connected to the concave hole, the height of the push rod 120 can be adjusted by rotating; the push rod 120 protrudes At the top of the main body 110, the multi-tube 200 is acted on by the part of the top rod 120 protruding from the main body 110, and a positioning slot 121 is provided at the end of the top rod 120 exposed from the main body 110. The positioning slot 121 is formed by a recessed arrangement at the end of the top rod 120. The positioning slot 121 can be in various shapes, as long as the bottom end of the multi-tube 200 can be inserted into the positioning slot 121. In an optional embodiment, the width of the positioning slot 121 is greater than or equal to the bottom ends of each tube of the multi-tube 200. For example, the positioning slot 121 is a circular groove, and the outer diameter of the bottom end of the tube of the multi-tube 200 is smaller than the width of the positioning slot 121, so that the bottom ends of each tube of the multi-tube 200 can be inserted into the positioning slot 121 for positioning. The number of top rods 120 can be designed according to needs. For example, if each row of 8 rows of storage holes 321 corresponds to one tube in the eight-tube package, then 12 columns of storage holes 321 can be used to install 12 eight-tube packages, and the number of top rods 120 is also 96, each corresponding to a storage hole 321. The eight-tube packages can also be arranged at intervals, so that the top rods 120 are also arranged in rows of eight, and each row is arranged at intervals, with a total of 48 top rods 120.
[0036] Please refer to Figure 4 When the storage rack 300 is placed on the top of the main body 110, the push rod 120 enters the above-mentioned cavity at the top of the main body 110, so that the push rod 120 can support the multi-tube 200 placed in the storage rack 300, and the bottom ends of each tube of the multi-tube 200 are positioned at the positioning notch 121. In this way, as long as the storage rack 300 covers the top of the main body 110 and a force is applied slightly downward to the storage rack 300 to reduce the gap between the storage rack 300 and the main body 110, the push rod 120 acts on the eight-tube joint placed in the storage rack 300, and the eight-tube joint is pushed out by the push rod 120. There is no need to pull out the eight-tube joint with force, and the tube cover will not be dirty. The operation is convenient and simple, without special requirements. Different operators can achieve the same use effect, which not only solves the difficulty of pulling out the tube, but also eliminates the hidden danger of the cover bursting due to loose cover, while ensuring the inspection quality risk caused by dirty tube cover.
[0037] The prior art is to pull the multi-tube 200 out of the rack by pulling out the tubes, but this method requires extremely high force from the operator, and requires that the tube caps must not be contaminated when pulling out the tubes. Since each tube of the multi-tube 200 contains liquid, it is difficult to pull out the tubes without contamination. In addition, if too much force is applied when pulling out the tubes, the tube caps will loosen, making it difficult to achieve homogeneous operations and uniformity during the experiment. However, the present application no longer needs to pull out the multi-tube 200 from the storage rack 300, thus eliminating the need for operation. The storage rack 300 is directly placed on the main body 110, and a slight downward force is applied to the storage rack 300. Since each tube of the multi-tube 200 is positioned by the positioning slot 121, the multi-tube 200 can be easily lifted from the storage rack 300 by utilizing the upward force of the push rod 120, thereby reducing the requirements for operators, assisting in homogenization operations, and facilitating the detachment of the multi-tube 200 from the rack. The detached multi-tube 200 can meet uniform standards, and also avoids problems such as contamination of the tube cover and loose tube cover.
[0038] In an optional embodiment, the size of the main body 110 matches the size of the storage rack 300, so that when the storage rack 300 is placed on the main body 110, the edge of the main body 110 can be aligned with the edge of the storage rack 300, such as the length, width and height of the main body 110 are equal to the length, width and height of the storage rack 300, so that when the storage rack 300 is placed on the top of the main body 110, the sides of the storage rack 300 are aligned with the sides of the main body 110. In an optional embodiment, the main body 110 is set as the same frame structure as the storage rack 300, and the multi-connected pipe disengagement device 100 is equipped with a push rod 120 on the basis of the frame structure. The frame structure can be an iron frame, and the push rod 120 is fixed to the main body 110 by welding, or it can be fixed by other methods, such as the main body 110 is made of plastic, the frame structure is provided with threaded holes, and the push rod 120 is threadedly connected to the frame structure through the threaded holes, and other settings can also be used.
[0039] In an optional embodiment, a plurality of push rods 120 are spaced apart and arranged in a straight line, so that each push rod 120 can correspond to the position of each tube of the multi-tube 200. For example, eight push rods 120 are used as a group, and each group corresponds to each row of 8 storage holes 321 of the storage rack 300. A push rod 120 can be set at the corresponding position of each storage hole 321, so that when the storage rack 300 is placed on the top of the main body 110, each push rod 120 can push out the tube placed in the storage hole 321. In an optional embodiment, a plurality of push rods 120 are arranged in an array, such as an 8*12 array arrangement as shown in the figure, and the position of each push rod 120 corresponds to each storage hole 321 of the storage rack 300. When the storage rack 300 is placed on the main body 110, the push rod 120 can just lift up the multi-tube 200, so that the multi-tube 200 is detached from the storage rack 300. In an optional embodiment, the push rod 120 can move axially relative to the main body 110 so that the height of the push rod 120 protruding from the main body 110 can be adjusted. The push rod 120 can be provided with a structural form that is convenient for adjusting the height. For example, the main body 110 is provided with a threaded hole, the push rod 120 is provided with an external thread, and the push rod 120 is threadedly connected to the main body 110, so that the height of the push rod 120 can be adjusted by rotation.
[0040] Please refer to Figure 5 In an optional embodiment, it also includes a first fixing member 130, which is fixed to the main body 110. The first fixing member 130 can be fixed to the main body 110 by welding, threaded connection or bolting. The first fixing member 130 can adopt a block structure and be provided with a threaded hole. The top rod 120 is threadedly connected to the first fixing member 130 so that the top rod 120 can move axially, and the top end of the top rod 120 always points to the direction of the top of the main body 110. In this way, the top rod 120 is vertically arranged on the main body 110, and the height can be adjusted by twisting the top rod 120. In an optional embodiment, a second fixing member 140 is further included. The second fixing member 140 is fixed to the main body 110, and can also be fixed to the main body 110 by welding, threaded connection or bolting. The second fixing member 140 also adopts a block structure. The second fixing member 140 is spaced apart from the first fixing member 130. On the main body 110, the second fixing member 140 is located below the first fixing member 130, and the bottom end of the push rod 120 is threadedly connected to the second fixing member 140. In this way, the upper and lower parts of each push rod 120 are respectively matched with the first fixing member 130 and the second fixing member 140. The functions of the first fixing member 130 and the second fixing member 140 are different. The first fixing member 130 is to facilitate the height adjustment of the push rod 120, and the function of the second fixing member 140 is to be able to limit the position of the push rod 120, so that the push rod 120 always maintains the height adjustment in the axial direction, and the connection of the push rod 120 is more stable and firm.
[0041] In an optional embodiment, the push rod 120 is provided with an external thread arranged along the axial direction, such as a 160mm, 4mm diameter cross head stainless steel screw, the positioning notch 121 is cross-shaped, and the bottom end of the multi-tube 200 is seated on the screw head of the screw, and the positioning slot is limited, so that the push rod 120 can stably lift the multi-tube 200 along the axial direction of each tube. In an optional embodiment, the first fixing member 130 and the second fixing member 140 are respectively provided with internal threaded holes passing through the top and bottom, the second fixing member 140 is located in the main body 110, and the first fixing member 130 is located at the top of the main body 110. The first fixing member 130 and the second fixing member 140 are respectively stainless steel nuts with a width of 40mm, and the two nuts are respectively arranged at the upper and lower parts of the screw.
[0042] Please refer to Figure 6Specifically, the main body 110 is provided with multiple rows of concave holes, which are hexagonal holes with a hole depth less than the length of the screw. The nut of the second fixing member 140 is placed at the bottom end position in the concave hole, so that the nut is always clamped in the concave hole, and the nut of the first fixing member 130 is slightly larger than the size of the concave hole. The first fixing member 130 is also embedded in the top position of the concave hole. The nut and the concave hole have an interference fit, so that the first fixing member 130 can be firmly clamped and cannot be loosened. In this way, two upper and lower nuts are formed in the main body 110, and each concave hole is provided with the first fixing member 130 and the second fixing member 140 in the above manner; in an optional embodiment, the first fixing member 130 protrudes from the top of the main body 110, and the size of the first fixing member 130 is larger than the size of the concave hole. The first fixing member 130 is connected to the main body 110 by a fixed connection method. If welding is used, the first fixing member 130 can also be directly tightened with the top rod 120. The rod body of the push rod 120 is threadedly connected to the two nuts mentioned above, so that the push rod 120 is screwed into the recessed hole by rotation, and the push rod 120 is always threadedly connected to the first fixing member 130. When the push rod 120 is connected to the second fixing member 140, two points of action are formed. The push rod 120 can be more stably adjusted up and down in the axial direction. Since the first fixing member 130 and the second fixing member 140 are both in the recessed hole, by adjusting the height of the push rod 120 protruding from the top of the main body 110, the bottom ends of each tube of the multi-tube 200 can be lifted when the storage rack 300 is placed on the main body 110. Each push rod 120 corresponds to a storage hole 321 of the storage rack 300, and multiple push rods 120 are adjusted to a uniform height so that each push rod 120 can provide the same force and operation to the multi-tube 200. In this way, when in use, the capped multi-tube 200 is easier to be separated from the storage rack 300. Each time the tube is taken out, the operation can be homogenized, and the liquid in the taken multi-tube 200 is stably stored to meet the requirements. The top rod 120 can also adjust the height at any time according to the needs, and the applicability is strong, and it can be used in eight-tubes and storage racks 300 of different specifications. On the other hand, the multi-tube detaching device 100 has a simple structure and low production cost. For example, the storage rack 300 of eight-tubes with 96 holes is priced at 2.6 yuan, 48 top rods 120 are about 4.8 yuan, and 96 nuts are 4.8 yuan in total. The cost of a single device 100 is not high, and the device 100 can also be reused for many times and for a long time.
