Description

Technical Field

[0001] This utility model relates to the field of auxiliary sampling technology, and in particular to a sedimentation bacteria monitoring bracket. Background Technology

[0002] The pharmaceutical and medical device industries have high requirements for environmental control in their production processes. Current Good Manufacturing Practices (GMP) for pharmaceuticals explicitly stipulate that dynamic microbial monitoring should be conducted to assess the microbial status of sterile production. Monitoring microorganisms in cleanrooms requires sampling airborne sedimentation bacteria. However, currently available stand systems are only single-headed, allowing only one petri dish to be placed at a time for monitoring one type of colony, resulting in low efficiency and failing to meet the need for simultaneous monitoring of different colony types. Purchasing additional stands increases costs. Furthermore, some monitoring stands lack sufficient space to place petri dish lids, and the trays for placing petri dishes are often flat, hindering airflow and posing a risk of interference with the sampling process. Even increasing the number of stands increases the area occupied by the stands, interfering with the workers' workspace during production and significantly increasing the risk of tripping. In addition, monitoring multiple petri dishes at different times not only doubles the workload for sampling personnel but also increases the duration of environmental monitoring, impacting workshop production scheduling and creating blind spots for monitoring sedimentation bacteria during critical production operations. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a sedimentation bacteria monitoring bracket that is convenient for placing multiple culture dishes in different positions and for placing dish lids at the monitoring point simultaneously.

[0004] To solve the above-mentioned technical problems, the present invention provides a settling bacteria monitoring support, including a support rod on a base, at least one first support part on one side of the support rod for supporting a culture dish, and at least one clamping part on the other side of the support rod for supporting a culture dish lid. A second support part connected to the support rod and assisting in supporting the culture dish lid is provided below each clamping part.

[0005] The above structure includes at least one first support portion for placing the culture dish, facilitating sampling at different spatial heights. A clamping portion horizontally limits the placement of the dish lid, while a second support portion vertically supports and limits the placement of the dish lid. The combined action of the second support portion and the clamping portion enables the dish lid to be positioned correctly. Simultaneously, the clamping portion is located near the first support portion, within the monitoring area of ​​the culture dish. Even when the culture dish is closed after monitoring, no colonies from external areas will be introduced, ensuring the accuracy of the monitoring results. The structure is simple and easy to use.

[0006] To facilitate placement and simplify the structure, preferably, each of the first support portions includes a connecting rod extending horizontally axially perpendicular to the support rod, with staggered first and second support rods connected to the extended end of the connecting rod.

[0007] To prevent the culture dish from falling due to impact, it is preferable that both the first and second support rods have a first limiting section extending vertically upward.

[0008] To prevent wear and tear on the outside of the petri dish and to prevent residue from contaminating the colonies, it is preferable to cover the first limiting segment with a first rubber sleeve.

[0009] To facilitate the placement of the lid and simplify the structure, preferably, each of the clamping parts includes a first stop bar extending horizontally perpendicular to the support rod, two second stop bars connected to the first stop bar, and a third stop bar adjustablely disposed on each of the second stop bars. The first stop bar, the two second stop bars, and the third stop bar together in the horizontal direction form a frame structure with an opening on the side away from the support rod.

[0010] To facilitate adjustment of the width of the clamping part for placement of lids of different sizes, it is preferable that the second stop has a threaded hole and the third stop is connected to a threaded rod that is screwed into the threaded hole, with the threaded rod and the third stop being set at a right angle.

[0011] To prevent wear and tear on the outside of the lid and to prevent residue from contaminating the bacterial colonies, it is preferable to provide a third rubber sleeve on both the second and third stops.

[0012] To facilitate installation and simplify the structure, and to better prevent wear and tear on the outer side of the lid, the second support preferably includes a third support rod fixed to the support rod and located below the first stop rod. The third support rod extends horizontally and has a fourth support rod bent upward at its extended end. A second rubber sleeve is sleeved through the third and fourth support rods.

[0013] To facilitate vertical placement of the petri dish lid while avoiding interference, it is preferable that the distance between the second and third rubber sleeves in the vertical projection is greater than or equal to the radius of the petri dish lid.

[0014] To facilitate horizontal placement of the petri dish lid while avoiding interference, it is preferable that the length of the second stop is adapted to the width of the rim of the petri dish lid.

[0015] Beneficial effects: This utility model is equipped with a first support part, a second support part, and a clamping part, which can not only place the culture dish, but also place the dish lid in the monitoring area. It can avoid the dish lid from affecting the accuracy of the culture dish collection results due to carrying colonies from the external area. The structure is simple and compact and easy to use.

[0024] Depend on Figure 1 , Figure 2 and Figure 3 As shown, the present invention includes a support rod 10 disposed on a base 1, at least one first support part 11 disposed on one side of the support rod 10 for supporting a culture dish, and at least one clamping part 13 disposed on the other side of the support rod 10 for supporting a culture dish lid. A second support part 12 connected to the support rod 10 and assisting in supporting the culture dish lid is provided below each clamping part 13.

[0025] Specifically, each of the first support parts 11 includes a connecting rod 110 extending horizontally in the direction perpendicular to the support rod 10. The extended end of the connecting rod 110 is connected to a first support rod 111 and a second support rod 112 arranged in an alternating manner. The first support rod 111 and the second support rod 112 are each provided with a first limiting section 113 extending vertically upward, and a first rubber sleeve 114 is fitted on the first limiting section 113.

[0026] Each of the clamping parts 13 includes a first stop 131 extending horizontally perpendicular to the axial direction of the support rod 10, two second stop 132 connected to the first stop 131, and a third stop 133 connected to each of the second stop 132. The first stop 131, the two second stop 132, and the third stop 133 together in the horizontal direction form a frame structure with an opening on the side away from the support rod 10.

[0027] A threaded hole is provided on the second stop 132, and a threaded rod 130 is connected to the third stop 133 and screwed into the threaded hole. The threaded rod 130 and the third stop 133 are arranged at right angles. A third rubber sleeve 134 is fitted on both the second stop 132 and the third stop 133.

[0028] The second support part 12 includes a third support rod 121 fixed on the support rod 10 and located below the first stop rod 131. The third support rod 121 extends horizontally and has a fourth support rod 122 bent upward at the extended end. A second rubber sleeve 123 is sleeved through the third support rod 121 and the fourth support rod 122.

[0029] The length of the second stop 132 is adapted to the width of the rim of the petri dish lid; the distance between the second rubber sleeve 123 and the third rubber sleeve 134 in the vertical projection is greater than or equal to the radius of the petri dish lid.

[0030] The working principle of this utility model is as follows:

[0031] For processes requiring long-term sedimentation bacteria monitoring, each monitoring point needs to provide a location for placing the petri dish lid. This makes it easy for external colonies outside the monitoring point to fall in when the lid is closed, which could affect the sampling accuracy. At the same time, during the operation of the equipment by staff, the petri dishes may be bumped and fall, which would also compromise the effectiveness of the sedimentation bacteria monitoring process.

[0032] like Figure 1 and Figure 2As shown, taking the setting of two first support parts 11 as an example, it not only solves the problem of low efficiency in monitoring colonies with a single petri dish, but also, the two first support parts 11 are staggered in the vertical direction on the support rod 10, so that petri dishes can be placed at two different heights to collect and monitor colonies, and the placement positions of the two petri dishes do not interfere with each other; at the same time, the extended end of the connecting rod 110 is connected to the staggered first support rod 111 and second support rod 112, which form a cross-shaped structure, which is conducive to air circulation at the lower outer end of the petri dish. Under the premise that the placement positions of the two petri dishes do not interfere with each other, it helps to improve the accuracy of collecting colonies in the air.

[0033] Furthermore, the gap between the first support rod 111 and the second support rod 112 facilitates the manual placement and removal of the culture dish, effectively preventing spillage of the sample due to tilting of the culture dish and ensuring the integrity of the sampling and monitoring results.

[0034] Both the first support rod 111 and the second support rod 112 are provided with a first limiting section 113 extending vertically upward, which limits the movement of the culture dish in the horizontal direction and can effectively prevent the culture dish from falling. At the same time, a first rubber sleeve 114 is fitted on the first limiting section 113 to prevent the outer wall of the culture dish from being worn when it moves on the support rod, and to prevent the generated wear impurities from entering the culture dish with the air, thereby affecting the accuracy of the data collection and monitoring results.

[0035] At the same time, the lid of the petri dish should not be placed far from the monitoring and collection position. However, if it is placed on the table at the collection position like the base 1, it will inevitably carry colonies from the lower space. When closing and tidying up the petri dish, other colonies carried on it will inevitably fall into the petri dish, which will also affect the accuracy of the sampling and collection results. Therefore, the clamping part 13 should be set at the same height as the first support part 11 on which the corresponding petri dish is placed.

[0036] Similarly, when placing the petri dish lid, to prevent wear on the outer wall of the lid as it moves along the support rod, and to prevent wear particles from entering the petri dish with the air and affecting the accuracy of the collected monitoring results, firstly, the length of the second stop rod 132 is adapted to the width of the petri dish lid's rim, facilitating the quick placement of the lid vertically; secondly, a third rubber sleeve 134 is fitted on both the second stop rod 132 and the third stop rod 133, and a second rubber sleeve 123 is fitted through the third support rod 121 and the fourth support rod 122. The vertical projection distance between the second rubber sleeve 123 on the third support rod 121 and the third rubber sleeve 134 on the second stop rod 132 is greater than or equal to the radius of the petri dish lid, thus always limiting the lid in the vertical direction and preventing it from falling off.

[0037] In addition, to prevent colonies from falling from high positions or petri dishes into the inner wall of the lid, the angle of the lid can be adjusted when necessary. Specifically, hold the third stop 133 on one side and twist it to rotate the threaded rod 130. While rotating, the third stop 133 gradually moves outward horizontally. Once it reaches the appropriate position, rotate the third stop 133 to the horizontal position. Then, twist the third stop 133 on the other side to the appropriate position and rotate it to the horizontal position. This ensures that the first stop 131, the two second stop 132, and the third stop 133 still form a frame structure with an opening on the side away from the support rod 10 in the horizontal direction.

[0038] At this point, the length of the exposed threaded section of the threaded rod 130 plus the length of the second stop 132 is much larger than the width of the lid's rim. The top of the upright lid needs to tilt outwards to rest against the third stop 133, while the bottom of the lid remains against the third support rod 121. This placement of the lid, with the lower end of the rim angled downwards, effectively shields the inner wall of the lid (e.g., ...). Figure 3 As shown by the dotted line at the bottom of the plate), this effectively reduces the height difference between the top and bottom of the plate lid when it is placed upright. This not only better prevents colonies from falling from higher-positioned petri dishes onto the inner wall of the lid, but also avoids colonies from other heights from adhering to the inner wall of the lid.

[0039] It should be noted that, firstly, the base 1 is made of steel plate. The thickness of the steel plate and the diameter of the support rod 10 should be set in combination with the height of the monitoring point and the load-bearing capacity of each support for the culture dish, so as to meet the stability requirements when placing it. In particular, the stability of placement should be considered when adjusting the extension length of the third stop rod 133.

[0040] Furthermore, the number of first support parts 11 in this embodiment is not unique, nor are the corresponding number of clamping parts 13 and second support parts 12. They should be specifically set according to actual usage needs in order to better form a multi-layer and / or single-layer multi-position monitoring pattern for sedimentation bacteria, so as to effectively improve the efficiency of collection and monitoring.
