Description

Technical Field

[0001] This utility model relates to the field of culture medium sampling technology, and in particular to a sampling device for culture medium processing. Background Technology

[0002] When sampling culture medium, the sampled culture medium needs to be sealed and preserved to ensure that the culture medium is not contaminated and to prevent inaccurate data and misjudgment. Therefore, sampling equipment is required. However, existing sampling equipment ignores sampling liquids at different depths in actual use and only samples liquids at the same depth, which makes sampling inconvenient.

[0003] The utility model patent with publication number CN222524547U provides a sampling device for processing cell culture medium. It uses an air pump to provide suction, which enables multiple sampling tubes to perform sampling operations simultaneously, thereby improving sampling efficiency and reducing the physical labor of operators. At the same time, by using sampling needles of different lengths, it is possible to sample samples at different depths, which facilitates the comparison of samples and improves the sampling and testing effect, bringing convenience to the sampling process.

[0004] Although the above method involves sampling at different depths, it requires changing the sampling needle to a different length to match the sampling depth, which is cumbersome and not very practical. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for culture medium processing, which solves the problem that when sampling samples at different depths, it is necessary to change the sampling needles of different lengths to match the sampling depth, which is cumbersome and not very practical.

[0006] To achieve the above objectives, this utility model provides a sampling device for culture medium processing, including a base plate and a sampling assembly. The sampling assembly includes two support frames, a support plate, an air pump, and multiple sampling structures. The two support frames are spaced apart on the base plate, and both ends of the support plate are fixedly connected to the two support frames respectively. The support plate is spaced apart above the base plate, and the air pump is located above the support plate. Multiple sampling structures are spaced apart on the support plate. Each sampling structure includes an installation cylinder, a sampling cylinder, a rubber stopper, and a connecting tube. The installation cylinder is threadedly connected to the support plate and passes through the support plate. The sampling cylinder is detachably connected to the installation cylinder and is located inside the installation cylinder. The rubber stopper is detachably connected to the sampling cylinder and is located at the upper end of the sampling cylinder. One end of the connecting tube is connected to the rubber stopper, and the other end of the connecting tube is connected to the output end of the air pump.

[0007] The sampling structure further includes a rotating plate, which is fixedly connected to the mounting cylinder and is located on the outside of the mounting cylinder.

[0008] The sampling tube is provided with a positioning bracket on its outer side, and the mounting tube has a positioning groove that is adapted to the positioning bracket, with the positioning bracket located inside the positioning groove.

[0009] The sampling structure further includes a rotating ring, which is threadedly connected to the mounting cylinder. The rotating ring is located at the upper end of the mounting cylinder and has an opening.

[0010] The sampling component further includes an adjustment structure, which includes a fixed cylinder, a threaded column, and a base. One end of the fixed cylinder is fixedly connected to the base plate, the other end of the fixed cylinder is threadedly connected to one end of the threaded column, and the other end of the threaded column is fixedly connected to the base.

[0011] This invention discloses a sampling device for culture medium processing. When sampling culture medium samples at different depths is required, the base plate is placed in a container holding the culture medium sample. The mounting cylinders are rotated to adjust the depth of each sampling cylinder in the culture medium sample. Then, an air pump is operated to draw the culture medium sample into each sampling cylinder for sampling at different depths. After sampling, the sampling cylinder is removed from the mounting cylinder, and the rubber stopper is pulled out, allowing the culture medium sample to be poured out for testing. When sampling culture medium samples at different depths, there is no need to change sampling needles of different lengths; the depth of the sampling cylinder in the culture medium can be adjusted directly through the mounting cylinder. This device is simple to operate, highly practical, and solves the problem of needing to change sampling needles of different lengths to match the sampling depth, which is cumbersome and impractical.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a sampling device for culture medium processing according to this utility model. Figure 2 This is a structural cross-sectional view of a sampling device for culture medium processing according to this utility model. Figure 3 This is a cross-sectional view of the rotating ring of a sampling device for culture medium processing according to this utility model.

[0019] This utility model provides a sampling device for culture medium processing, including a base plate 100 and a sampling assembly. The sampling assembly includes two support frames 210, a support plate 220, an air pump 230, and multiple sampling structures and adjustment structures. The sampling structure includes an installation cylinder 240, a sampling cylinder 250, a rubber stopper 260, a connecting pipe 270, a rotating plate 280, and a rotating ring 290. The adjustment structure includes a fixed cylinder 310, a threaded column 320, and a base 330.

[0020] In this specific embodiment, two support frames 210 are spaced apart on the base plate 100. Both ends of the support plate 220 are fixedly connected to the two support frames 210 respectively. The support plate 220 is spaced apart above the base plate 100. The air pump 230 is positioned above the support plate 220. Multiple sampling structures are spaced apart on the support plate 220. The mounting cylinder 240 is threadedly connected to the support plate 220 and passes through the support plate 220. The sampling cylinder 250 is detachably connected to the mounting cylinder 240 and is located inside the mounting cylinder 240. The rubber stopper 260 is detachably connected to the sampling cylinder 250 and is located at the upper end of the sampling cylinder 250. One end of the connecting pipe 270 is connected to the rubber stopper 260, and the other end of the connecting pipe 270 is connected to the output end of the air pump 230. The support frame 210 supports the support plate 220, which is used to mount the mounting cylinder 240. The mounting cylinder 240 is rotatable relative to the support plate 220. When the mounting cylinder 240 rotates, the length of the mounting cylinder 240 at its upper and lower ends relative to the support plate 220 changes, thereby allowing the height of the sampling cylinder 250 installed in the mounting cylinder 240 to be adjusted. The rubber stopper 260 seals the sampling cylinder 250, and the connecting pipe 270 connects to the air pump 230. When the air pump 230 operates, it generates suction, creating negative pressure inside the sampling cylinder 250, thereby drawing the culture medium sample into the sampling cylinder 250 for sampling. When sampling culture medium samples at different depths is required, the base plate 100 is placed into the container holding the culture medium sample. Each mounting cylinder 240 is rotated to adjust the depth of each sampling cylinder 250 in the culture medium sample. Then, the air pump 230 is run to draw the culture medium sample into each sampling cylinder 250 for sampling at different depths. After sampling, the sampling cylinder 250 is removed from the mounting cylinder 240, and the rubber stopper 260 is pulled out, allowing the culture medium sample to be poured out for testing. When sampling culture medium samples at different depths, there is no need to change sampling needles of different lengths; the depth of the sampling cylinder 250 in the culture medium can be adjusted directly through the mounting cylinder 240. This method is simple to operate and highly practical, solving the problem of needing to change sampling needles of different lengths to match the sampling depth, which is cumbersome and impractical.

[0021] Furthermore, the rotating plate 280 is fixedly connected to the mounting cylinder 240, and the rotating plate 280 is located on the outside of the mounting cylinder 240. The rotating plate 280 is provided on the outside of the mounting cylinder 240, allowing the mounting cylinder 240 to be rotated.

[0022] Specifically, a positioning bracket 251 is provided on the outer side of the sampling tube 250, and the mounting tube 240 has a positioning groove 241 adapted to the positioning bracket 251, with the positioning bracket 251 located inside the positioning groove 241. When the sampling tube 250 is placed in the mounting tube 240, the positioning bracket 251 is aligned with the positioning groove 241 and inserted to position the sampling tube 250, thereby facilitating the fixation of the sampling tube 250.

[0023] The rotating ring 290 is threadedly connected to the mounting cylinder 240. The rotating ring 290 is located at the upper end of the mounting cylinder 240 and has an opening 291. The rotating ring 290 can rotate relative to the mounting cylinder 240. When installing the sampling cylinder 250, the rotating ring 290 is rotated so that the opening 291 of the rotating ring 290 coincides with the positioning groove 241. Only then can the positioning bracket 251 be inserted into the positioning groove 241 through the opening 291. Then, the rotating ring is rotated again so that the opening 291 is misaligned with the positioning groove 241. At this time, the rotating ring 290 blocks the positioning bracket 251, preventing the positioning bracket 251 from sliding out of the positioning groove 241, thereby fixing the sampling cylinder 250 inside the mounting cylinder 240.

[0024] Additionally, one end of the fixed cylinder 310 is fixedly connected to the base plate 100, and the other end of the fixed cylinder 310 is threadedly connected to one end of the threaded post 320, the other end of which is fixedly connected to the base 330. The adjustment structure is used to adjust the height of the base plate 100, allowing this culture medium processing sampling device to be suitable for deeper culture medium samples. The threaded post 320 can rotate relative to the fixed cylinder 310. When the threaded post 320 rotates, its length within the fixed cylinder 310 changes, thereby adjusting the overall length formed by the threaded post 320 and the fixed cylinder 310, and thus adjusting the height of the base plate 100.

[0025] When sampling using a culture medium processing sampling device, first rotate the threaded column 320 to adjust the height of the base plate 100, then rotate the rotating ring 290 so that the opening 291 of the rotating ring 290 coincides with the positioning groove 241. Insert the positioning bracket 251 through the opening 291 into the positioning groove 241, and then rotate the rotating ring so that the opening 291 and the positioning groove 241 are misaligned. At this time, the rotating ring 290 blocks the positioning bracket 251, thereby fixing the sampling cylinder 250 inside the mounting cylinder 240. The rubber stopper 260 is inserted into the sampling tube 250 to seal the sampling tube 250. The base 330 is placed into the container holding the culture medium sample. Each of the mounting tubes 240 is rotated to adjust the depth of each of the sampling tubes 250 in the culture medium sample. Then, the air pump 230 is run to draw the culture medium sample into each of the sampling tubes 250 to sample the culture medium sample at different depths. After sampling is completed, the sampling tube 250 is removed from the mounting tube 240, and the rubber stopper 260 is pulled out. The culture medium sample can then be poured out from the sampling tube 250 for testing.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
