[0032] Example
[0033] This embodiment provides a loading bracket, such as Figure 1 and Figure 2 As shown, at least one loading position 11 is provided at the upper end of the loading bracket, and the loading position 11 is suitable for loading the sampling cover 2; the loading position 11 is configured with a limiting groove 141, and the limiting groove 141 is extended along a first direction, and the first direction and the horizontal plane are intersected; a limiting wall 142 is provided in the limiting groove 141, and the limiting wall 142 is suitable for abutting against the outer end surface of the sampling cover 2 to support the sampling cover 2.
[0034] In this embodiment, if Figure 1 and 2 As shown, the limiting groove 141 is configured as a semi-closed groove body, and the loading bracket loads the sampling cover 2 through one or more loading positions 11. The loading position 11 is provided with a limiting groove 141 extending along the first direction and intersecting with the horizontal plane, so that the sampling cover 2 can be placed non-horizontally at the loading position 11 to reduce the contact area between the outer end face of the sampling cover 2 and the loading bracket, thereby reducing the risk of cross-contamination caused by contact during the placement process and reducing the impact of false positives.
[0035] During the specific placement process, the user operates the sampling cover 2 through the gloves in the isolator, so that part of the sampling cover 2 is placed in the limiting groove 141 and the other part is placed outside the limiting groove 141.
[0036] In a specific implementation, the first direction may be arranged to be inclined with respect to the horizontal plane; preferably, the first direction is arranged as the height direction, and the limiting groove 141 extends vertically along the height direction.
[0037] Regarding the limiting groove 141 limiting the sampling cover 2, as shown in FIG. Figure 2 As shown, taking the sampling cover 2 as a cylindrical table structure as an example, the limiting wall 142 is suitable for contacting the lateral outer edge end face of the sampling cover 2, and the limiting groove 141 is also provided with a stop wall. When it can be inclined with the horizontal plane in the first direction, the stop wall is suitable for contacting the lateral radial end face of the sampling cover 2, and the limiting wall 142 plays the role of limiting support for the sampling cover 2.
[0038] In some embodiments, Figure 2As shown, the inner cavity of the limiting groove 141 is set to a tapered structure, and the opening size of the upper end of the inner cavity of the limiting groove 141 is larger than the opening size of the lower end of the inner cavity of the limiting groove 141. The upper end opening of the limiting groove 141 is used for taking and placing the sampling cover 2, and the tapered structure can play a role in limiting and supporting the sampling cover 2. The lower end opening can facilitate the loading bracket to clean the limiting groove 141. The entire loading bracket is compact, which is conducive to the planning and management of the internal space of the isolator.
[0039] In this embodiment, the loading bracket includes a supporting plate body 14 , the upper side end surface of the supporting plate body 14 is extended along a horizontal plane, and the limiting groove 141 is formed in a concave shape on the supporting plate body 14 .
[0040] In some embodiments, the lower end opening of the limiting groove 141 can be protruded from the lower end surface of the support plate body 14 to increase the area of the limiting wall 142 in the limiting groove 141, thereby achieving a good supporting and limiting effect on the sampling cover 2.
[0041] In one embodiment, the limiting wall surface 142 is symmetrically arranged in the limiting groove 141, and the limiting wall surface 142 is respectively arranged at both ends of the limiting groove 141 along its length direction. In another embodiment, the limiting wall surface 142 is arranged on one side of the limiting groove 141 in the length direction, and the other side of the limiting groove 141 is arranged as a vertical wall surface, and the sampling cover 2 is supported and supported only by the limiting wall surface 142 on one side, and the sampling cover 2 is limited by the vertical wall surface on the other side.
[0042] In a specific embodiment, the limiting wall surface 142 is configured as an arc-shaped curved surface, which conforms to and contacts the lateral outer edge end surface of the sampling cover 2 .
[0043] As a further embodiment, Figure 3 As shown, a supporting wall body 143 with a protruding arrangement is formed in the limiting groove 141 , and the limiting wall surface 142 is constructed on the upper end surface of the supporting wall body 143 , and directly supports the sampling cover 2 through the supporting wall body 143 .
[0044] As an optional implementation, Figure 3 As shown, there are multiple supporting walls 143, and the multiple supporting walls 143 are arranged in two rows, and the supporting walls 143 in any row are arranged at intervals from each other. This arrangement is conducive to reducing the contact area between the limiting wall surface 142 and the lateral outer edge end surface of the sampling cover 2, and reducing the risk of cross contamination caused by contact during placement.
[0045] In one embodiment, the two rows of supporting walls 143 are symmetrically arranged. In another embodiment, the two rows of supporting walls 143 are staggeredly arranged in the limiting grooves 141 .
[0046] In this embodiment, the limiting groove 141 is configured as a groove structure recessed on the support plate 14 . In other embodiments, the limiting groove 141 is configured as a groove structure constructed in a supporting protrusion structure protruding from the upper end surface of the support plate 14 .
[0047] As a further embodiment, Figure 1 As shown, one or more placement areas are provided on the upper end surface of the support plate body 14 ; as one of the basic implementations, a loading position 11 and a placement area are provided on the support plate body 14 .
[0048] In this embodiment, a hollow structure 17 is provided on the placement area, and the hollow structure 17 is set through the support plate body 14. In this setting, the placement area is equipped with a hollow structure 17 to avoid blocking the flow of airflow. The hollow structure 17 can be set as a small round hole screen or a long strip of fence grille. The hollow structure 17 allows the airflow in the isolator to flow from the support plate body 14 from top to bottom, meeting the continuous monitoring requirements of the environment in the isolator space during the actual working stage.
[0049] In some embodiments, the upper end surface of the support plate body 14 is provided with a first placement area 12 and a second placement area 13 which are spaced apart from each other, and the loading position 11 is arranged between the first placement area 12 and the second placement area 13. The first placement area 12 and the second placement area 13 can be used to place culture dishes. For example, untested culture dishes are placed in the first placement area 12, and tested culture dishes are placed in the second placement area 13. This arrangement is conducive to the placement of culture dishes in the isolator, and is also convenient for users to distinguish and handle. In the specific operation process, the first placement area 12 and the second placement area 13 can be marked to identify the respective functions to be placed, so that users can easily identify them.
[0050] In the above description, the loading position 11 is not limited to the limited supporting sampling cover 2, and other covers may also be provided, such as the end cover of the culture dish; in specific operation, the sampling cover 2 and the end cover of the culture dish on the loading position 11 are interchangeable. When the bacterial strain is detected, the sampling cover 2 is placed on the loading position 11, and when the bacterial strain is not detected, the end cover of the culture dish is placed on the loading position 11.
[0051] The loading bracket provided in this embodiment is intended to reduce the area of the sampling cover 2 in the horizontal projection when it is placed. For example, the sampling cover 2 is placed vertically so that when no bacterial species detection is performed, no additional floating bacteria will be collected on the sampling cover 2. At the same time, when the cover body is replaced, the loading position 11 can also receive the end cover of the culture dish.
[0052] In this embodiment, the support plate body 14 is specifically configured as a rectangular plate structure. In other embodiments, the support plate body 14 can be configured as an L-shape, a square structure, etc., and can be conformally matched to the layout inside the isolator according to the spatial configuration of the isolator.
[0053] As a further embodiment, Figure 1 As shown, a placement position 16 is also provided at the upper end of the loading bracket, and the placement position 16 and the loading position 11 are arranged at intervals. The placement position 16 can be used to place the end cap of the culture dish. There are one or more placement positions 16, and the number is configured according to demand. The placement position 16 can be set to the same structure as the loading position 11, and the structural size of the placement position 16 is configured to be conformed to the end cap of the culture dish. This arrangement can facilitate the temporary storage of the sampling cover 2 and the end cap of the culture dish, and can reduce the risk of cross contamination between the two. In a specific embodiment, the placement position 16 can be extended along the first direction. Preferably, the placement position 16 is arranged vertically along the height direction.
[0054] In some embodiments, Figure 1 As shown, the loading bracket includes three or more legs 15, the legs 15 are fixedly connected to the support plate 14, and the legs 15 are connected to the lower end surface of the support plate 14. Any two legs 15 are arranged at intervals to establish a stable support condition for the support plate 14, so that the upper end surface of the support plate 14 can obtain a horizontal state.
[0055] In this embodiment, if Figure 1 and Figure 4 As shown, the sampling cover 2 includes a body 21 and a handle 22. The body 21 is configured as a rotating body structure, and the handle 22 is fixedly connected to the outer peripheral side of the body 21. The limiting groove 141 can accommodate a part of the body 21, and the other part of the body 21 is placed outside the limiting groove 141. With this configuration, the part of the body 21 connected to the handle 22 can be placed outside the limiting groove 141 to facilitate the user to operate and place. In the specific operation process, when the sampling cover 2 is placed horizontally, when the user operates with the isolator gloves, the isolator gloves contact the additional handle 22, which can prevent the isolator gloves from entering the space above the sampling cover 2 during operation, which is conducive to reducing the probability of impurities such as bacteria on the wall of the isolator gloves entering the sampling cover 2.
[0056] In the above description, the sampling cover 2 can be specifically configured as a sampling cover body for planktonic bacteria.
[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
