Description

Technical Field

[0001] The invention belongs to the technical field of microbial culture equipment, and in particular relates to a highly airtight lined culture dish loading box. Background Art

[0002] In activities such as microbial culture testing, it is necessary to use culture media to culture microorganisms and proliferate them for testing and research. The culture medium is placed in a culture dish, and the biological sample is dipped into an inoculation loop and then a line path is drawn on the surface of the culture medium to distribute the sample to the surface of the culture medium. In most cases, the biological sample needs to be pretreated with a specific agent, then formed into a dispersed suspension, and finally streaked. Since the standard culture dish is only a cylindrical box and does not have the function of directly completing the above-mentioned multiple procedures, it is necessary to cooperate with multiple sample containers and preparation tools to transfer, prepare, and streak materials. This process causes the culture medium and samples to be exposed to the environment multiple times, increasing the probability of contamination of the sample and culture medium. At the same time, the cumbersome operation is not conducive to the realization of batch automated culture. Summary of the Invention

DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to specific embodiments.

[0032] The present application discloses a highly sealed streaking culture dish loading box, which is mainly used to fix and support traditional culture dishes, improve the sealing performance of the inside and outside of the culture dishes during the streaking process, and prevent the sample and culture medium from being contaminated.

[0033] Its main structure is as follows Figures 1 to 5 As shown, it includes a base 1 for supporting and positioning a culture dish 2, a culture dish for holding culture medium, a box cover 3 for protection and isolation, and a functional part 4 for facilitating streaking and sample dispersion; to ensure the safety of biological materials, the base 1, the box cover 3 and the functional part 4 should be processed and manufactured using materials and processes that meet the requirements of the corresponding health and technical specifications.

[0034] In actual use, the base 1 needs to cooperate with various automatic or manual marking equipment to support and position the culture dish and prevent it from moving during the marking process. Therefore, a lower receiving groove 1a is provided on the top of the base 1. The shape of the lower receiving groove 1a is consistent with the shape of the culture dish 2;

[0035] When in use, the culture dish is placed in the lower receiving groove 1a. In actual production, the base 1 preferably adopts a plastic shell structure and a double-layer shell. The inner shell surrounds the lower receiving groove 1a, and the outer shell can be provided with a support or connection structure with the marking equipment and other structures, while isolating and protecting the inner shell.

[0036] In order to facilitate connection and fixation, mutually cooperating snap-fit ​​connection structures are provided on the front side of the base 1 and the rear side of the functional component 4. The functional component 4 is fixed to the front side of the base 1 through the snap-fit ​​connection structure.

[0037] The bayonet connection method is simple and efficient, and can realize the rapid assembly of the base 1 and the functional part 4. In actual use, the commonly used bayonet connection method can be selected according to the front and back docking method of the two.

[0038] The cover 3 is mainly used for protection and isolation and as part of the marking control structure. The cover 3 is buckled on the top of the base 1 and the functional component 4. The bottom of the cover 3 is provided with an upper receiving groove 3a. The shape of the upper receiving groove 3a is consistent with the shape of the culture dish 2. The front side of the upper receiving groove 3a is provided with an inner inlet and outlet 3b; elastic blocking pieces 6 are respectively provided on both sides of the inner inlet and outlet 3b.

[0039] The outer sides of the two elastic blocking pieces 6 are connected to the box cover 3, and the inner sides are close to the center of the inner inlet and outlet 3b and cover the inner inlet and outlet 3b; the lower receiving groove 1a and the upper receiving groove 3a are arranged opposite each other and enclose a culture dish receiving cavity, and the culture dish 2 is arranged in the culture dish receiving cavity;

[0040] The functional part 4 is provided with a collection hole 4a, in which a magnetic marking head 5 is provided. The front side of the functional part 4 is provided with an external inlet and outlet 4b communicating with the collection hole 4a, and the external inlet and outlet 4b is directly connected with the internal inlet and outlet 3b.

[0041] In actual use, the marking head located in the collection hole 4a can be controlled to move by magnetic attraction, and enter the culture dish after passing through the external inlet and outlet 4b and the internal inlet and outlet 3b to perform the marking operation. During the operation of the magnetic attraction structure, there is no need to directly open the box cover.

[0042] Two elastic baffles form the isolation structure between the internal space of the culture dish and the external marking head access channel. The elastic baffle structure is simple and does not require complex assembly methods. In actual implementation, the elastic baffle 6 can be made of PVC material and fixed to both sides of the internal inlet and outlet 3b by adhesive. When the marking head is driven by magnetic force, the elastic baffle will be compressed and deformed to open, allowing the marking head to enter and exit smoothly. After the marking head leaves, the elastic baffle returns to its original shape, thereby achieving automatic protection and isolation. The use of elastic baffle 6 can effectively maintain the isolation effect between the culture dish and the external environment. The elastic baffle 6 has a simple structure and is easy to operate and use, effectively ensuring the smoothness of the marking process.

[0043] The collection hole 4a is used to make the marking head contact with the sample or process the sample. In order to better achieve the sealing effect and facilitate the replenishment of samples or reagents, a filling hole 4c is also provided on the functional part 4. The bottom of the filling hole 4c is provided with a channel connected to the collection hole 4a; samples or reagents can be added through the filling hole and enter the collection hole through the channel, so that the marking head inside the collection hole can contact and carry the sample. In this way, there is no need to open or disassemble the functional part for operation, and the channel is used to achieve relative closed isolation of the collection hole. A replenishment hole 3c connected to the filling hole 4c is provided on the box cover 3 for easy operation.

[0044] In order to improve the efficiency of samples and reagents reaching the collection hole and prevent them from staying in the filling hole after filling, as a preferred solution, the bottom of the channel connecting the filling hole 4c and the collection hole 4a is a slope, and the higher side of the slope is located at the bottom of the filling hole 4c, and the lower side is located at the bottom of the collection hole 4a, so that the sample or reagent can automatically flow into the collection hole by utilizing the fluid's own weight.

[0045] The functional part 4 can be manufactured as a whole or adopt other structures as a supporting structure of the culture dish. It should be as light as possible and easy to assemble and disassemble. Therefore, as a preferred solution, in this embodiment, the functional part 4 is composed of an upper shell 40 and a lower shell 41 connected by a snap fastener;

[0046] The top of the lower shell 41 is open, and transverse clips 410 for plugging with the base 1 are provided on both sides of the lower shell 41. The channel connecting the filling hole 4c and the collection hole 4a is surrounded by the inner wall of the lower shell 41;

[0047] The communicating groove 401 and the filling hole 4c are formed by the local downward depression of the upper shell 40, and the collecting hole 4a is formed by the downward depression of the bottom structure of the communicating groove 401; the bottoms of the collecting hole 4a and the filling hole 4c are connected with the inner cavity of the lower shell 41, and the external inlet and outlet 4b are dug out from the rear side wall of the communicating groove 401.

[0048] The panel-shell splicing structure is simpler and more compact, allowing for easy design and fabrication of internal channels and a lighter structure. The panel-shell adapts to the plug-in structure, making assembly and disassembly easy. When necessary, the internal channel status and information can be directly observed, facilitating analysis and testing during the culture process. To facilitate connection, vertical clips 402 are provided on both sides of the lower end surface of the upper shell 40. Corresponding slots are provided on the lower shell 41 to engage with the vertical clips 402. The clips and slots provide a flexible connection between the two. Once connected, the upper shell is held down by the lid, further ensuring overall structural stability.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
