[0001] The embodiments of this disclosure relate to the field of pharmaceutical equipment technology, and more specifically, to a sterile isolator for unpacking and sterilizing disposable freeze-drying trays. Background Technology
[0002] Disposable freeze-drying trays are widely used in pharmaceuticals, biotechnology, and other fields, playing a crucial role in the freeze-drying process of drugs. However, when sterilizing and unpacking disposable freeze-drying trays, a sterile isolator is often required to ensure a sterile environment.
[0003] Currently, numerous problems have been exposed in the process of stacking materials (such as disposable freeze-drying trays) into aseptic isolators. On the one hand, due to the limited internal space of the aseptic isolator and the complexity of the operating procedures, operators find it difficult to find the appropriate angle and position when stacking materials, resulting in uneven stacking and significantly impacting stacking efficiency. On the other hand, the entire stacking process requires operators to be extremely careful and adjust the material position multiple times, which not only consumes a lot of time but also requires a significant investment of energy, resulting in extremely high workload and a significant increase in labor costs. Utility Model Content

[0039] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0040] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0042] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0045] like Figures 1-5As shown, a sterile isolator for sterilizing and unpacking disposable freeze-drying trays according to an embodiment of the present disclosure is provided. The sterilization chamber 1 has an inlet 11 that communicates with the interior of the sterilization chamber 1. A suspension bracket 2 is rotatably disposed inside the sterilization chamber 1 and has a plurality of hooks 21 for suspending packaging bags 3 containing freeze-drying trays 4. The suspension bracket 2 is arranged such that when rotated, the plurality of hooks 21 sequentially approach the inlet 11.
[0046] For example, such as Figure 1-2 As shown, to address the technical problems of difficult and time-consuming stacking of materials in the isolator, a sterile isolator for unpacking disposable freeze-drying trays was designed. The inlet 11 is located on one side of the sterilization chamber 1 and is designed with a relatively wide opening to facilitate the operator in feeding in the packaging bags 3 containing the freeze-drying trays 4. The suspension bracket 2 is installed at the center of the sterilization chamber 1 via a rotating shaft. The rotating shaft can be manually rotated or connected to a drive motor, whose operation precisely controls the rotation of the suspension bracket 2. The hooks 21 are evenly distributed along the circumference of the suspension bracket 2, and the hooks 21 can stably hold the packaging bags 3 containing the freeze-drying trays 4.
[0047] The operator stands in front of the inlet 11 and hangs the packaging bags 3 containing freeze-drying trays 4 one by one on the hooks 21 near the inlet 11, from the inside out. At this time, the operator presses the control button, starting the drive motor and causing the suspension bracket 2 to slowly rotate at a certain angle, moving the next batch of hooks 21 to the position of the inlet 11. The operator then hangs subsequent packaging bags 3 on these hooks 21 from the inside out, repeating the above operation until all hooks 21 are full of packaging bags 3. Afterwards, the sealing door of the inlet 11 is closed, and the sterilization program is started to thoroughly sterilize the freeze-drying trays 4 inside the chamber.
[0048] This design makes material stacking simple and orderly. Operators no longer need to frequently adjust positions within the cramped sterilization chamber 1 to find suitable placement points; they can simply wait at the inlet 11 for the hooks 21 to approach in sequence to easily complete the material stacking. This not only saves a significant amount of time and manpower but also avoids space waste and material damage caused by haphazard stacking, greatly improving work efficiency and the accuracy of material stacking.
[0049] In some examples, the suspension bracket 2 has several mounting brackets 22 and several suspension hooks 21 located on the mounting brackets 22.
[0050] For example, such as Figure 1-3As shown, the mounting bracket 22 on the suspension bracket 2 is designed as a horizontal bar, which is fixed to the suspension bracket 2 by a stable connection method such as welding or slots. Each horizontal bar is equipped with multiple hooks 21. The hooks 21 are curved hooks that facilitate the hanging and picking up of the packaging bag 3, thus better securing the packaging bag 3 and preventing it from slipping.
[0051] When installing the hanging hooks 21, first install the horizontal rod-shaped mounting bracket 22 onto the hanging bracket 2 to ensure it is secure and stable. Then, install the hanging hooks 21 on the horizontal rod at certain intervals to ensure that the distance between each hanging hook 21 is uniform, making it convenient to hang the packaging bags 3.
[0052] The mounting bracket 22 makes the installation of the suspension hooks 21 more stable and reliable. The design of the crossbar increases the installation area of the suspension hooks 21, allowing for a more reasonable distribution of the suspension hooks 21 and making full use of the space of the hanging bracket 2. At the same time, it facilitates flexible adjustment of the position and spacing of the suspension hooks 21 according to different specifications of packaging bags 3 and freeze-drying trays 4, improving the versatility and adaptability of the equipment and ensuring that various materials can be hung safely and orderly.
[0053] In some examples, a sterile isolator for unpacking disposable freeze-drying trays also includes an unpacking box 5, which is disposed on one side of the sterilization chamber 1 and has a transfer channel 51 that connects to the sterilization chamber 1; an unpacking device 6 is disposed inside the unpacking box 5 for unsealing the packaging bag 3; a transfer operation plate 7 is rotatably disposed on the side wall of the feed inlet 11 and has a plurality of first operation holes 71; the transfer operation plate 7 is arranged to close the feed inlet 11 after rotation, and the first operation holes 71 are used for installing isolation gloves.
[0054] For example, such as Figure 1-3 As shown, the unpacking box 5 is positioned close to one side of the sterilization box 1, and the two are connected by a transfer channel 51. The design of the transfer channel 51 allows the freeze-drying tray 4 to move between the two boxes while ensuring the relative independence of the sterile environment. The transfer operation panel 7 is mounted on the side wall of the feed inlet 11 via a rotating shaft. The unpacking device 6 is installed inside the unpacking box 5, and its structure is designed to unseal the packaging bag 3.
[0055] After the freeze-drying trays are installed, the operator rotates the control panel 7 to close the feed inlet 11, and then begins the sterilization process. After sterilization, the operator inserts their hands, fitted with isolation gloves through the first operating port 71, into the sterilization chamber 1 to remove the packaging bag 3 containing the freeze-drying tray 4 from the hanging hook 21. The bag 3 is then moved through the transfer channel 51 to the unpacking box 5. Once inside the unpacking box 5, the unpacking device 6 is activated to unseal the packaging bag 3.
[0056] In some examples, a sterile isolator for unpacking disposable freeze-drying trays also includes an unpacking operation panel 8 disposed on an unpacking box 5, the unpacking operation panel 8 having a second operation hole 81 for installing isolation gloves.
[0057] For example, such as Figure 1-3 As shown, the unpacking operation panel 8 is installed on the outer wall of the unpacking box 5 for easy operation by the operator. Second operation holes 81 are distributed on the unpacking operation panel 8, and each operation hole is fitted with an isolation glove to effectively prevent outside air and impurities from entering the unpacking box 5. The operator can use the isolation gloves to insert their hands through the second operation holes 81 into the unpacking box 5 to precisely operate the unpacking device 6.
[0058] After the freeze-drying tray 4 is transferred into the unpacking box 5, the operator, wearing protective gloves, inserts both hands into the second operating port 81. The packaging bag 3 is unsealed by operating the control button or handle of the unpacking device 6. During the operation, the operator can observe the unpacking process in real time through the transparent window inside the unpacking box 5 to ensure accuracy. After unpacking, the freeze-drying tray 4 is removed from the packaging bag 3.
[0059] In some examples, a sterile isolator for unpacking and sterilizing disposable freeze-drying trays also includes an isolation plate 9, which is slidably disposed within the sterilization chamber 1 and is arranged to close the transfer channel 51 after sliding.
[0060] For example, such as Figure 1-3 As shown, the isolation plate 9 is slidably installed inside the sterilization chamber 1 via guide rails. This ensures that the isolation plate 9 slides smoothly and steadily without any jamming.
[0061] During sterilization, the telescopic cylinder is in the retracted state, and the transfer channel 51 is blocked. When sterilization is complete and it is necessary to connect the sterilization chamber 1 and the unpacking chamber 5, the telescopic cylinder is activated, the cylinder extends, and pushes the isolation plate 9 to slide along the guide rail until the transfer channel 51 is opened.
[0062] The isolation plate 9 can effectively isolate the sterilization box 1 and the unpacking box 5, and flexibly control the communication status between the two boxes at different operation stages.
[0063] In some examples, the unpacking device 6 includes a first clamping plate 61 disposed inside the unpacking box 5; a second clamping plate 62 slidably disposed relative to the first clamping plate 61, forming a clamping space between the second clamping plate 62 and the first clamping plate 61, one side of the packaging bag 3 moves into the clamping space, and the second clamping plate 62 is arranged to slide close to the first clamping plate 61 to clamp the packaging bag 3; and an unpacking knife 63 is slidably disposed relative to the first clamping plate 61 along the length direction of the first clamping plate 61, and the unpacking knife 63 is arranged to slide to cut the packaging bag 3 so that the freeze-drying tray 4 can be removed from the packaging bag 3.
[0064] For example, such as Figure 4-5 As shown, the first clamping plate 61 is fixedly installed on one side inside the unpacking box 5 to facilitate the placement of the packaging bag 3. The second clamping plate 62 is slidably installed relative to the first clamping plate 61 via a guide rail, the design of which allows the second clamping plate 62 to slide along a straight line. The unpacking knife 63 is slidably installed on the second clamping plate 62 along the length of the first clamping plate 61 via a slider or other structure.
[0065] After the packaging bag 3 containing the freeze-drying tray 4 is transferred into the unpacking box 5, the operator moves one side of the packaging bag 3 into the clamping space between the first clamping plate 61 and the second clamping plate 62. Then, the drive mechanism is activated, causing the second clamping plate 62 to slide along the guide rail closer to the first clamping plate 61, tightly clamping the packaging bag 3. Next, the drive mechanism of the unpacking knife 63 is activated, causing the unpacking knife 63 to slide along the length of the first clamping plate 61, cutting the packaging bag 3, so that the freeze-drying tray 4 can be smoothly removed from the packaging bag 3.
[0066] The design of this unpacking device 6 enables automatic clamping and cutting of the packaging bag 3, improving the efficiency and accuracy of unpacking. The cooperation of the first clamping plate 61 and the second clamping plate 62 can stably fix the packaging bag 3, preventing it from moving or shaking during the cutting process and ensuring the quality of the cut. The sliding design of the unpacking knife 63 makes the cutting process more stable and smooth, avoiding problems such as uneven cutting and damage to the freeze-drying tray 4 that may occur during manual unpacking, thus ensuring the quality and integrity of the freeze-drying tray 4.
[0067] In some examples, the first clamping plate 61 has a first knife groove 611, and the second clamping plate 62 has a second knife groove 621; the first knife groove 611 and the second knife groove 621 are arranged close to each other and overlap each other, and the unpacking knife 63 passes through and is slidably disposed in the second knife groove 621.
[0068] For example, such as Figure 4-5 As shown, the shape and size of the first cutting groove 611 on the first clamping plate 61 and the second cutting groove 621 on the second clamping plate 62 are matched to ensure that the unpacking knife 63 can pass through smoothly. When the second clamping plate 62 is close to the first clamping plate 61, the first cutting groove 611 and the second cutting groove 621 can overlap each other.
[0069] The first groove 611 and the second groove 621 provide a cutting path for the unpacking knife 63, ensuring the straightness and stability of the cut. The groove design prevents the unpacking knife 63 from deviating during the cutting process, avoiding damage to the freeze-drying tray 4 and improving the quality and safety of the cut.
[0070] In some examples, the unpacking device 6 includes a first mounting frame 64, a second clamping plate 62 disposed on the first mounting frame 64, and an unpacking knife 63 slidably disposed on the first mounting frame 64; a first telescopic member 65 is disposed inside the unpacking box 5; the extended end of the first telescopic member 65 is connected to the first mounting frame 64, and the first telescopic member 65 is arranged such that after extension, the second clamping plate 62 slides close to the first clamping plate 61.
[0071] For example, such as Figure 4-5 As shown, the first mounting bracket 64 is installed inside the unpacking box 5, and its structural design provides stable support for the second clamping plate 62 and the unpacking knife 63. The second clamping plate 62 is fixed to the first mounting bracket 64, and the unpacking knife 63 is slidably mounted on the first mounting bracket 64 via guide rails or other means, ensuring smooth sliding of the unpacking knife 63. The first telescopic member 65 is installed on the inner wall of the unpacking box 5, and its protruding end is connected to the first mounting bracket 64. The movement of the second clamping plate 62 is controlled by its telescopic movement.
[0072] When it is necessary to clamp the packaging bag 3, the first telescopic component 65 is activated, and its extended end extends, pushing the first mounting frame 64 and the second clamping plate 62 to slide together along the guide rail, so that the second clamping plate 62 moves close to the first clamping plate 61 to clamp the packaging bag 3. When cutting the packaging bag 3, the unpacking knife 63 slides on the guide rail on the first mounting frame 64 to perform the cutting operation.
[0073] In some examples, the unpacking device 6 includes a slide rail mounted on a first mounting bracket. The unpacking knife 63 is slidably mounted on the first mounting bracket 64 via the slide rail. The slide rail is inclined, with one end of the slide rail being farther from the first clamping plate 61 than the other end is farther from the first clamping plate 61. The unpacking knife 63 is arranged to slide obliquely upward along the slide rail and then gradually slide into the second knife groove 621. The unpacking knife 63 slides in the opposite direction along the slide rail and then gradually moves out of the second knife groove 621, so that the unpacking knife 63 cuts the packaging bag 3 but does not sever it.
[0074] For example, such as Figure 4-5 As shown, the inclined slide rail creates an angle between the sliding direction of the unpacking knife 63 and the second clamping plate 62, which enables the unpacking knife 63 to achieve the best effect when cutting the packaging bag 3.
[0075] When cutting the packaging bag 3, the drive mechanism moves the unpacking blade 63 diagonally upwards along the slide rail. The unpacking blade 63 gradually slides into the second cutting groove 621 and cuts the packaging bag 3, at which point the freeze-drying tray 4 can be removed from the packaging bag 3. After cutting, the drive mechanism reverses its movement, causing the unpacking blade 63 to slide diagonally downwards and gradually move out of the second cutting groove 621. At this point, the packaging bag 3 is cut but still maintains a certain connection, facilitating subsequent processing.
[0076] This oblique cutting method allows the packaging bag 3 to maintain a certain connection after cutting, facilitating subsequent disposal of the waste bag. It avoids the potential contamination of the sterile environment by scattered fragments after the packaging bag 3 is completely cut, and also makes it easier to collect and dispose of the waste bags in a unified manner.
[0077] In some examples, a sterile isolator for unpacking disposable freeze-drying trays also includes a conveying device 10 disposed inside an unpacking box 5, which is used to move the freeze-drying trays 4 detached from the packaging bag 3 to outside the unpacking box 5.
[0078] For example, such as Figure 1-2 As shown, the conveying device 10 can take the form of a conveyor belt or conveyor rollers and is installed inside the unpacking box 5. The surface of the conveyor belt is designed with anti-slip textures to better drive the movement of the freeze-drying trays 4. The drive motor of the conveyor belt is installed outside the unpacking box 5 and is connected to the conveyor belt through a transmission device to ensure stable operation of the conveyor belt.
[0079] After the unpacking device 6 completes the unpacking operation, the freeze-drying tray 4 is placed on the conveyor belt. The drive motor is started to smoothly move the freeze-drying tray 4 from inside the unpacking box 5 to outside the unpacking box 5, so that it can enter the subsequent production process. During the conveying process, the operator can monitor the conveying status of the freeze-drying tray 4 in real time through the observation window.
[0080] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
