Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology for cleanrooms in the biopharmaceutical industry, specifically to a special flat dish holder for cleanroom dispensing lines. Background Technology

[0002] During the packaging and production of pharmaceutical products in cleanrooms, it is crucial to conduct simultaneous environmental monitoring of the cleanroom packaging line. Among these methods, offline settling bacteria and online airborne bacteria sampling are the two most critical microbial monitoring techniques.

[0003] Traditional methods for environmental monitoring in cleanroom filling lines involve placing settling bacteria monitoring plates and spare airborne bacteria plates on a platform below the filling line or on the surface of accessories next to the product transport track. However, due to the complex structure of the transport track above the platform and some filling equipment accessories, available space is extremely limited. Visual analysis of cleanroom airflow patterns revealed that some settling bacteria monitoring plates placed on the platform below the filling line are obstructed by components of the filling line equipment above, preventing sampling from meeting the first-pass airflow (FIRST AIR) monitoring requirements.

[0004] Furthermore, the inconsistent heights of the platform below the packaging line, the fixed beams of the transfer track, and the accessories beside the track prevent the sedimentation bacteria monitoring plates from being at the same height during traditional sedimentation bacteria sampling and monitoring in packaging lines. This not only makes it difficult to ensure the accuracy of the monitoring data but also fails to meet the requirements for using RABS gloves during packaging production. Therefore, monitoring personnel have to open the isolator door to change sedimentation and airborne bacteria plates, which significantly increases the risk of contamination.

[0005] In view of the above problems, it is particularly necessary to design a special flat plate holder suitable for cleanroom dispensing lines. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model provides a dedicated petri dish holder for cleanroom dispensing lines, which provides a platform for offline sedimentation bacteria monitoring and sampling, and can also temporarily hold spare petri dishes and online airborne bacteria sampling heads, thus facilitating operation.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0008] A special plate holder for a cleanroom dispensing line includes a plate placement rack and a fixed bracket. The plate placement rack is fixedly connected to the fixed bracket, which is used to fix and support the plate placement rack. The plate placement rack is provided with a monitoring position for placing sedimentation bacteria monitoring plates and a temporary storage position for placing airborne bacteria sampling heads and spare plates.

[0009] As a preferred technical solution, the outer periphery of the plate holder is provided with multiple baffles, which are used to restrict the movement of the plates.

[0010] As a preferred technical solution, the plate rack is racetrack shaped.

[0011] As a preferred technical solution, the flat dish rack is provided with at least two baffles on each of its two long sides and at least one baffle on each of its two curved sides.

[0012] As a preferred technical solution, the flat dish rack has three baffles on each of its two long sides and one baffle on each of its two curved sides.

[0013] As a preferred technical solution, the dish rack is made of 316 stainless steel.

[0014] As a preferred technical solution, the plate holder has multiple air holes evenly distributed on it, and the air holes are round holes.

[0015] As a preferred technical solution, the fixing bracket is in the form of a clamp.

[0016] As a preferred technical solution, the flat dish rack and the fixed bracket are fixed by welding or fastening screws.

[0017] As a preferred technical solution, the relative height of the dish rack and the fixed bracket is adjustable. The bottom of the dish rack is provided with a vertical adapter rod, and the side of the fixed bracket is provided with a horizontal connecting rod. The connecting rod has a through hole for the adapter rod to pass through vertically. The adapter rod and the connecting rod are slidably connected and locked in place by a tightening screw.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model relates to a dedicated plate holder for cleanroom filling lines, applicable to filling line environments with limited space and no flat work surface. The holder can be fixed to an online airborne bacteria holder or other equipment accessories and tubing. During use, it allows for convenient sampling and plate changing of both offline settling bacteria and online airborne bacteria monitoring in the cleanroom filling line environment, using RABS gloves within the isolator.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] A special plate holder for cleanroom dispensing lines, such as Figure 1As shown, the device includes a petri dish rack 1 and a fixed support 2. The petri dish rack 1 is fixedly connected to the fixed support 2, which is used to fix and support the petri dish rack 1. The petri dish rack 1 is provided with a monitoring position 11 and a temporary storage position 12. The monitoring position 11 is used to place the petri dish for settling bacteria monitoring and to carry out sampling and monitoring work after opening the lid of the petri dish for settling bacteria monitoring. The temporary storage position 12 is used to temporarily store the online airborne bacteria sampling head and the lids of spare petri dishes and settling bacteria monitoring petri dishes.

[0029] The dish rack 1 has multiple baffles 13 on its outer periphery to restrict the movement of the dishes. Preferably, the dish rack 1 is racetrack-shaped, with at least two baffles 13 on each of its two long sides and at least one baffle 13 on each of its two curved sides, allowing the dishes to be placed within the area defined by the baffles 13 and preventing them from slipping. In one specific embodiment, the dish rack 1 is made of 316 stainless steel, approximately 225mm long, 115mm wide, and 1.5mm thick; it has three baffles 13 on each of its two long sides and one baffle 13 on each of its two curved sides, for a total of eight baffles; all baffles 13 are approximately 8mm wide and 7mm high.

[0030] Preferably, the dish rack 1 has a plurality of evenly distributed ventilation holes 14, which are circular holes with a diameter of approximately 20 mm. The ventilation holes 14 allow airflow to pass smoothly through the dish rack when no dishes are placed on it, without affecting the airflow organization in the clean area.

[0031] Preferably, the fixing bracket 2 is in the shape of a clamp and can be fixed to the tubing of the online airborne bacteria support or other equipment accessories that can be used for fixing, so as to provide a fixed support for the petri dish rack 1. Preferably, the petri dish rack 1 and the fixing bracket 2 are fixed by welding; another preferred embodiment is that the petri dish rack 1 and the fixing bracket 2 are fixed by fastening screws. More preferably, such as Figure 2 As shown, the bottom of the dish rack 1 is vertically equipped with an adapter rod 15, and the side of the fixed bracket 2 is horizontally equipped with a connecting rod 21. The connecting rod 21 has a through hole for the adapter rod 15 to pass through vertically. The adapter rod 15 and the connecting rod 21 are slidably connected and locked in place by a tightening screw 22. The slidable connection between the adapter rod 15 and the connecting rod 21 allows the relative height of the dish rack 1 and the fixed bracket 2 to be adjusted. The height of the dish rack 1 can be adjusted at different fixed positions, so that the position of the dish rack 1 at each monitoring point is consistent. The range of motion of the monitoring personnel using RABS gloves is basically consistent, thereby ensuring the accuracy of the monitoring data.

[0032] Before production begins, place the spare petri dishes for offline settling bacteria and online airborne bacteria in the temporary storage position 12 of the petri dish rack 1, and then place the settling bacteria sampling petri dish on the monitoring position 11. After opening the lid of the settling bacteria sampling petri dish, the lid can also be placed on top of the spare petri dishes in the temporary storage position 12.

[0033] During production, monitoring personnel can conveniently perform offline settling bacteria and online airborne bacteria changing operations on the petri dish rack 1 using the RABS gloves of the isolation system. When changing petri dishes for online airborne bacteria, the online airborne bacteria sampling head can be temporarily placed in the storage position, and then reinstalled after changing the dish.

[0034] All sedimentation bacteria sampling and monitoring points and plate changing operations are kept at the same height. This not only facilitates operation and improves monitoring efficiency and ensures monitoring accuracy, but also meets the need for operation with RABS gloves during production, thereby avoiding the risk of contamination from opening doors.

[0035] This utility model relates to a special plate holder for cleanroom dispensing lines, applicable to dispensing line environments with limited space and no flat work surface. The holder can be fixed to the online airborne bacteria holder or other equipment accessories and pipes, while the settling bacteria monitoring plates are placed on the plate holder, ensuring that the sampling and monitoring height of all settling plates on the dispensing line is consistent. This ensures that the laminar flow of gas in the cleanroom flows vertically downward into the settling bacteria monitoring plates, avoiding any form of obstruction and meeting the requirements of the first-pass airflow.

[0036] This utility model relates to a dedicated petri dish holder for cleanroom dispensing lines. The petri dish holder has a monitoring position and a temporary storage position. The monitoring position is mainly used to place petri dishes for settling bacteria monitoring and to conduct sampling and monitoring. The temporary storage position is used to temporarily store spare petri dishes, monitoring dish caps, and online airborne bacteria sampling heads. This allows for complete sampling and monitoring of settling bacteria and online airborne bacteria, as well as dish changing operations, using RABS gloves from the cleanroom isolator. This reduces the number of times the isolator door needs to be opened during dispensing, effectively avoiding the risk of contamination introduced during door opening operations. Since all petri dish holders are at the same height, the range of motion of monitoring personnel using RABS gloves remains basically consistent, further ensuring the accuracy of monitoring data.

[0037] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
