[0002] The microbial specimen is generally collected by using a culture medium for transportation, and the microbial specimen is temporarily stored in the culture medium. Currently, the collection and storage of the microbial specimen are generally used separately, so that the culture medium with the transportation mode cannot have the functions of culture, observation or storage, and is not convenient for the use of the operator.

[0003] As disclosed in the publication No. CN201962276U, a transportation culture medium is in a tubular structure. When the transportation culture medium is used, the operator places the sample collected by the swab head in the culture medium, and the distribution of the bacterial colony is easier to observe when the bacterial colony is formed. Meanwhile, the transportation culture medium is convenient for collection, transportation and storage, and is convenient for the operator to use.

[0004] However, when the swab head containing the sample is placed in the culture medium after the sampling is completed, the limiting protruding column of the end cover needs to be matched with the opening of the transportation culture medium container to realize the covering. If the limiting protruding column lacks an inclined surface or a guide structure, the operator needs to align the limiting protruding column with the opening of the transportation culture medium container to cover, which makes the limiting protruding column unable to guide the covering, increases the operation difficulty of the covering, reduces the convenience and efficiency of the operation, and affects the user-friendliness and the foolproof performance of the overall structure.

It can be understood that when the outer side of the connecting sub 121 has the rough surface 1211, the friction between the connecting sub 121 and the inner wall of the culture medium pipe body 200 can be increased during the covering operation, further preventing the situation that the end cap 100 slips off after covering. In this embodiment, the setting of the rough surface 1211 can increase the friction between the inner wall of the transition part 210 and the connecting sub 121.

[0045] As shown in the drawings, Figure 1 or Figure 2 As shown in the drawings, in one embodiment, the outer side of the end cap body 110 has an anti-skid strip 111. In this embodiment, the operator can hold the culture medium pipe body 200 by hand to pick up the tube portable sampling type microbial culture medium 10, or can pick up the tube portable sampling type microbial culture medium 10 by the anti-skid strip 111. Since the outer side of the end cap body 110 is provided with the anti-skid strip 111, the situation that the sample is damaged due to hand slip when the operator picks up the tube portable sampling type microbial culture medium 10 is prevented.

[0046] In one embodiment, the length of the limiting part 220 is less than the length of the transition part 210, and the length of the limiting part 220 is less than the length of the storage part 230.

[0047] Compared with the prior art, the present disclosure has at least the following advantages:

[0048] In the above-mentioned tube portable sampling type microbial culture medium 10, the end cap 100 has an end cap body 110 and a limiting protruding column 120, and the limiting protruding column 120 has a connecting sub 121 and a guiding sub 122, wherein the side wall of the guiding sub 122 is an inclined surface, which plays a guiding role when the end cap 100 is covered. Therefore, the operator can realize covering without aligning the limiting protruding column 120 with the opening of the culture medium pipe body 200 by eyes, thereby reducing the operation difficulty when the end cap 100 is covered, ensuring the convenience and efficiency of the operation. When the covering operation is completed, the top of the culture medium pipe body 200 is located in the limiting ring groove 1001, so as to further fix the end cap 100 to prevent loosening. In addition, the operator places the sample in the tube portable sampling type microbial culture medium 10 after sampling by the sampling rod 300, so as to observe the colony distribution. The tube portable sampling type microbial culture medium 10 is convenient to transport, so that the portability of the culture medium is better.
