Abstract
Description
Technical Field
[0001] This utility model relates to the field of pretreatment rack technology, specifically a sample pretreatment rack for intestinal flora detection. Background Technology
[0002] In the gut microbiota detection process, sample pretreatment is a crucial preliminary step for obtaining accurate test results. Based on the above, the inventors have discovered the following problems: existing pretreatment racks have relatively rudimentary methods for fixing sample tubes. Most pretreatment racks use simple open grid or slot structures, which cannot effectively constrain the movement of the tubes on the rack. In gut microbiota testing samples, some require static sedimentation to separate solid and liquid components, such as fecal suspension samples. These samples have extremely high stability requirements. However, in actual operation, because the slot gaps in the pretreatment rack are larger than the diameter of the sample tubes, the tubes cannot be fixed inside. When staff handle other tubes, adjacent tubes are easily shaken. This shaking not only disrupts the sedimentation and stratification of the sample but also causes the precipitated microorganisms to resuspend.
[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a sample pretreatment rack for intestinal flora detection, in order to achieve a more practical value. Utility Model Content
[0004] The purpose of this invention is to provide a sample pretreatment rack for intestinal flora detection, in order to solve the problem mentioned in the background art that the existing pretreatment racks have a relatively simple method of fixing sample tubes, and most sample pretreatment racks adopt a simple open grid or slot structure, which cannot effectively restrict the movement of test tubes on the rack.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A sample pretreatment rack for intestinal flora detection includes a sealing mechanism and a placement mechanism. The placement mechanism includes a first placement rack, a second placement rack fixedly mounted on the bottom side of the first placement rack, and a third placement rack fixedly mounted on the bottom side of the second placement rack. The first, second, and third placement racks decrease in size with each other. The upper ends of the first, second, and third placement racks are respectively provided with a plurality of first, second, and third slots. Each of the first, second, and third slots has a pair of movable grooves on both sides inside. A clamping block is slidably mounted on the facing surface of each pair of movable grooves. The sealing mechanism includes a protective cover, which is fitted over the outside of the first, second, and third placement racks.
[0007] The beneficial effects of adopting the above-mentioned further solution are that the progressively decreasing structure of the first, second, and third placement racks of the placement mechanism allows for the orderly placement of intestinal flora detection samples of different sizes, making it convenient for users to place different types of intestinal flora detection samples; the first, second, and third slots, together with the clamping blocks, can firmly fix the sample containers, which is suitable for sample containers of different diameters and prevents them from being easily touched when placed in the first, second, and third slots; the protective cover of the sealing mechanism can protect the samples and prevent damage to the sample containers caused by improper operation during the experiment.
[0008] Furthermore, springs are fixedly installed on the inner side of each movable groove, and the other end of each spring is fixedly connected to the clamping block.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the spring in the movable slot is connected to the clamping block. When the sample container is placed, the spring is compressed to make the clamping block clamp the container. The elastic force provides a stable clamping force, which avoids the sample container being unable to be fixed in the first slot, second slot and third slot due to mismatch in diameter size, and is easy to be moved accidentally.
[0010] Furthermore, a cushioning pad is fixedly installed at the bottom of the interior of the first slot, the second slot, and the third slot. The cushioning pad is made of sponge material and has grooves.
[0011] The beneficial effects of adopting the above-mentioned further solution are that the sponge cushioning pad is set at the bottom of the slot, which can effectively buffer the impact force when the sample container is placed and prevent damage to the bottom of the container; the groove design can better fit the shape of the bottom of the container, further fix the sample container, and enhance the placement stability.
[0012] Furthermore, a heating sleeve is fitted on the outer side of the first slot inside the first placement frame, and the inner wall of the heating sleeve abuts against the outer wall of the first slot.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the heating jacket on the outside of the first slot can heat the sample, meet the temperature requirements in the pretreatment process of some samples, ensure that the sample is pretreated at a suitable temperature, and improve the sample treatment effect and detection accuracy.
[0014] Furthermore, an electronic tag plate is embedded on one side of the upper end of the first, second, and third placement racks, and a control panel is embedded on one side of the third placement rack.
[0015] The advantages of adopting the above-mentioned further solutions are that the electronic tag can record sample-related information, such as sample number, test items, and collection time, which makes it convenient for operators to quickly identify and manage samples; the control panel allows operators to set the temperature and heating time of the heating mantle and change the information on the electronic tag, thereby improving sample preprocessing efficiency.
[0016] Furthermore, magnets are embedded in both sides of the bottom of the first, second, and third placement racks, and iron sheets are embedded in both sides of the bottom of the inner side of the protective cover, with the iron sheets and magnets magnetically connected.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the magnets at the bottom of the first, second and third placement racks are magnetically connected to the iron sheet inside the protective cover, which allows for quick and stable installation and removal of the protective cover, facilitating sample storage and retrieval.
[0018] Furthermore, the protective cover is made of transparent acrylic material, and a handle is fixedly installed at the upper end of the protective cover. The beneficial effects of adopting the above-mentioned further solution are that the transparent acrylic material protective cover allows operators to directly observe the sample status without opening the cover; the handle makes it easy for users to lift the cover, improving operational convenience.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The intestinal flora detection sample pretreatment rack has a progressively decreasing structure of the first, second, and third placement racks, which can orderly place intestinal flora detection samples of different specifications, making it convenient for users to place different types of intestinal flora detection samples; the first, second, and third slots, together with the clamping blocks, can firmly fix the sample containers, suitable for sample containers of different diameters, and prevent them from being easily touched when placed in the first, second, and third slots; the protective cover of the closed mechanism can protect the samples and prevent damage to the sample containers caused by improper operation during the experiment; the spring in the movable slot is connected to the clamping block, and when the sample container is placed, the spring is compressed to make the clamping block clamp the container, using elastic force to provide stable clamping force, preventing the sample container from being unable to be fixed in the first, second, and third slots due to incompatible diameter, and preventing it from being easily moved; the electronic tag can record relevant sample information, such as sample number, detection item, collection time, etc., which facilitates the operator to quickly identify and manage the samples; the control panel allows the operator to set the temperature and heating time of the heating jacket and change the information on the electronic tag, improving the efficiency of sample pretreatment.

[0026] Please see Figures 1-4This utility model provides a technical solution: a pretreatment rack for intestinal flora detection samples, including a sealing mechanism 1 and a placement mechanism 2. The placement mechanism 2 includes a first placement rack 201, a second placement rack 202 fixedly installed on the bottom side of the first placement rack 201, and a third placement rack 203 fixedly installed on the bottom side of the second placement rack 202. The first placement rack 201, the second placement rack 202, and the third placement rack 203 decrease in size layer by layer. The upper ends of the first placement rack 201, the second placement rack 202, and the third placement rack 203 are respectively provided with a plurality of first slots 206, second slots 205, and third slots 204. A pair of movable grooves 207 are opened on both sides inside the first slot 206, the second slot 205, and the third slot 204. A clamping block 21 is slidably installed on the facing surface of each pair of movable grooves 207. 1; The sealing mechanism 1 includes a protective cover 101, which is fitted over the outside of the first placement rack 201, the second placement rack 202, and the third placement rack 203. The layered structure of the first placement rack 201, the second placement rack 202, and the third placement rack 203 of the placement mechanism 2 allows for the orderly placement of intestinal flora detection samples of different sizes, facilitating the placement of different types of intestinal flora detection samples by the user. The first slot 206, the second slot 205, and the third slot 204, in conjunction with the clamping block 211, can securely fix the sample container, suitable for sample containers of different diameters, and prevent them from being easily touched when placed in the first slot 206, the second slot 205, and the third slot 204.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-4Springs 212 are fixedly installed on the inner side of the movable slot 207, and the other end of each spring 212 is fixedly connected to the clamping block 211. Buffer pads 213, made of sponge material, are fixedly installed at the bottom of the first slot 206, second slot 205, and third slot 204, and grooves are provided on the buffer pads 213. Heating sleeves 210 are fitted inside the first placement rack 201 on the outer side of the first slot 206, with the inner wall of the heating sleeve 210 abutting against the outer wall of the first slot 206. Electronic label plates 209 are embedded on one side of the upper end of the first placement rack 201, second placement rack 202, and third placement rack 203. A control panel 208 is embedded on one side of the third placement rack 203. The springs 212 in the movable slot 207 are connected to the clamping blocks 211. When a sample container is placed, the springs 212 are compressed, causing the clamping blocks 211 to clamp the container, providing a stable clamping force using elasticity to prevent the sample container from being damaged. The sample container cannot be securely fixed inside the first slot 206, second slot 205, and third slot 204 due to mismatched diameter dimensions, making it prone to accidental movement. A sponge-material buffer pad 213 is placed at the bottom of the slot to effectively cushion the impact during sample container placement, preventing damage to the bottom. The groove design better adapts to the shape of the container's bottom, further securing the sample container and enhancing placement stability. The heating sleeve 210 on the outside of the first slot 206 can heat the sample, meeting the temperature requirements of some sample pretreatment processes, ensuring that the sample is pretreated at a suitable temperature, improving sample processing efficiency and detection accuracy. The electronic tag 209 can record sample-related information, such as sample number, detection item, and collection time, facilitating quick identification and management of samples by operators. The control panel 208 allows operators to set the temperature and heating time of the heating sleeve 210 and modify the information on the electronic tag 209, improving sample pretreatment efficiency. The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] Please see Figures 1-4Magnets 214 are embedded on both sides of the bottom of the first placement rack 201, the second placement rack 202, and the third placement rack 203. Iron sheets 103 are embedded on both sides of the bottom of the inner part of the protective cover 101. The iron sheets 103 are magnetically connected to the magnets 214. The protective cover 101 is made of transparent acrylic material, and a handle 102 is fixedly installed on the upper end of the protective cover 101. The magnets 214 at the bottom of the first placement rack 201, the second placement rack 202, and the third placement rack 203 are magnetically connected to the iron sheets 103 inside the protective cover 101, which allows for quick and stable installation and removal of the protective cover 101, facilitating sample storage and retrieval. The transparent acrylic material of the protective cover 101 allows operators to directly observe the sample status without opening the protective cover 101. The handle 102 makes it easy for users to open the protective cover 101, improving operational convenience.
[0030] Specifically, the working principle of this intestinal flora detection sample pretreatment rack is as follows: During use, the operator places the sample container into the first slot 206 of the first placement rack 201, the second slot 205 of the second placement rack 202, or the third slot 204 of the third placement rack 203, depending on the type of sample container. When the sample container is placed, the spring 212 connected to the clamping block 211 in the movable groove 207 is compressed. The spring 212 is compressed, causing the clamping block 211 to clamp the container, achieving a stable fixation. The sponge buffer pad 213 at the bottom of the slot and its groove design further buffer the impact force and adapt to the bottom of the container, enhancing placement stability. If the sample is pretreated… Heating is required. The temperature and heating time of the heating sleeve 210 outside the first slot 206 are set via the control panel 208 on one side of the third placement rack 203 to heat the sample. Simultaneously, operators can record the sample number and testing item information on the electronic label plate 209 on the upper side of the first, second, and third placement racks 201, 202, and 203 for easy management. After the sample is placed, the protective cover 101 is quickly fitted onto the outside of the first, second, and third placement racks 201, 202, and 203 via the magnetic connection between the inner bottom iron plate 103 and the bottom magnet 214 of the placement rack, protecting the sample. The transparent acrylic protective cover 101 allows for real-time observation of the sample status. When sample handling is required, the protective cover 101 can be opened via the handle 102 for storage and retrieval. The entire process is efficient, convenient, and ensures sample safety and pretreatment effectiveness.
