Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a novel high-sealing pharmaceutical isolator. Background Technology

[0002] Currently, pharmaceutical isolators are core equipment for ensuring aseptic drug production and protecting the safety of operators. The sealing performance of the rubber operating gloves at the operating port is crucial and needs to be verified through regular inflation tests.

[0003] Current methods for testing the seal of isolator gloves mostly rely on either "disassembling the glove for individual testing" or "in-situ manual clamping for sealing testing." The former requires repeated disassembly and reassembly of the glove, which is not only cumbersome and takes more than 30 minutes per test, but also easily damages the sealing connection between the glove and the fixing ring during disassembly, increasing the risk of contamination in subsequent production. The latter, although it does not require disassembly, requires manually clamping the glove cuff with a clamp to form a sealed space. The accuracy of the operation depends on human experience, and insufficient clamping force can easily lead to seal failure. Furthermore, it cannot quickly achieve simultaneous testing of multiple operating ports, making it difficult to meet the efficient and accurate testing needs of the pharmaceutical industry. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel high-sealing pharmaceutical isolator.

[0005] This utility model is achieved using the following technical solution: A novel high-sealing pharmaceutical isolator includes a pharmaceutical isolator body. One side of the pharmaceutical isolator body has multiple operating ports. Each operating port is fixedly fitted with a fixing ring. Each fixing ring is fixedly fitted with an operating glove. One side of each fixing ring has a detection component that allows for quick sealing checks of the operating glove without disassembling it. Each detection component has a fixing component that assists in quickly sealing and fixing the detection component with adjacent fixing rings. The detection component includes a sealing plate fitted to one side of the fixing ring. A pressure sensor for detecting the internal pressure of the operating glove is fixedly installed on the sealing plate. One side of the sealing plate is fixedly connected to an air inlet pipe for injecting air into the operating glove.

[0006] Through the above technical solution, the detection component can quickly verify the sealing performance of the operating gloves without disassembling them, by sealing the sealing plate and the fixing ring together, and by combining the air inlet pipe inflation and pressure sensor detection. The fixing component can ensure the sealing reliability of the sealing plate and the fixing ring, avoid air leakage during inflation, and solve the problems of low efficiency and poor sealing of existing detection methods.

[0007] As a further improvement to the above solution, an annular sealing groove is provided on the side of the fixing ring near the sealing plate, and an annular sealing strip is fixedly installed on the side of the sealing plate near the fixing ring, the annular sealing strip being adapted to the annular sealing groove.

[0008] Through the above technical solution, the matching and cooperation between the annular sealing strip and the annular sealing groove can further enhance the sealing performance between the sealing plate and the fixed ring, prevent air leakage from the contact surface between the two during inflation testing, and ensure the accuracy of pressure test data.

[0009] As a further improvement to the above solution, a sealing ring is fixedly installed on the side of the sealing plate near the fixing ring, and one side of the sealing ring is in contact with one side of the fixing ring.

[0010] Through the above technical solution, the sealing ring can form a "double seal" on the basis of the annular sealing strip, further blocking the gas leakage path, which is especially suitable for high-pressure inflation test scenarios and improves the sealing redundancy of the test components.

[0011] As a further improvement to the above solution, a first connecting block is fixedly installed on the cylindrical surface of the sealing plate, and a second connecting block is rotatably installed on one side of the first connecting block. One side of the second connecting block is fixedly installed with one side of the pharmaceutical isolator body, for rotating and storing the sealing plate when not in use.

[0012] Through the above technical solution, the rotational cooperation between the first connecting block and the second connecting block can realize the "rotational storage" of the sealing plate. When not being tested, the sealing plate can be rotated away from the operating port to avoid blocking the operating port and affecting normal production operations, thereby improving the flexibility of equipment use.

[0013] As a further improvement to the above solution, the fixing component includes locking blocks fixedly installed on both sides of the fixing ring, and fixing strips with "T"-shaped sliding grooves fixedly installed on both sides of the sealing plate. A third connecting block is slidably installed inside each of the two sliding grooves, and a hook plate is fixedly installed on one side of each of the two third connecting blocks. The two hook plates are adapted to the adjacent locking blocks, and one side of each hook plate and one side of each locking block are inclined in a mutually adapted manner to facilitate the hook plates hooking the adjacent locking blocks.

[0014] Through the above technical solution, the cooperation between the "T"-shaped sliding groove and the third connecting block can restrict the hook plate to slide only in the horizontal direction; the inclined surfaces of the hook plate and the locking block are adapted to achieve "quick fastening", and the initial fixing of the sealing plate can be completed without complicated operations, improving the preparation efficiency before testing. When it is necessary to open the sealing plate, it is only necessary to slide the hook plate and separate it from the locking block.

[0015] As a further improvement to the above solution, a first fixing plate is fixedly installed on the cylindrical surface of the sealing plate. A second fixing plate is provided on one side of the first fixing plate and fixedly installed with the fixing ring. A threaded post is provided on the other side of the first fixing plate. One end of the threaded post is fixedly installed on the first fixing plate and extends into the interior of the second fixing plate. The threaded post is threadedly engaged with the second fixing plate. A rotating block is fixedly installed on the other end of the threaded post.

[0016] Through the above technical solution, the rotating threaded column can drive the first fixed plate to move closer to the second fixed plate through the threaded engagement, thereby pushing the sealing plate to fit tightly with the fixed ring, ensuring that the annular sealing strip is fully embedded in the annular sealing groove, achieving "precise pressure sealing" and avoiding the problem of uneven sealing caused by manual pressing.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention enables rapid testing of the sealing performance of operating gloves through in-situ sealing of the detection component and the fixing ring, reducing the time required for a single test and significantly improving testing efficiency. The combination design of the annular sealing strip and the sealing ring, along with the pressure fixing of the threaded column, ensures no air leakage during the testing process and accurate and reliable pressure sensor data. The sealing plate can be rotated and stored without affecting normal production. The quick-locking structure of the hook plate and the locking block lowers the threshold for manual operation, allowing test preparation to be completed without professional skills.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Please combine Figures 1-4 This embodiment of a novel high-sealing pharmaceutical isolator includes a pharmaceutical isolator body 1. The pharmaceutical isolator body 1 has multiple operating ports 2 on one side. Each operating port 2 is fixedly installed with a fixing ring 3. Each fixing ring 3 is fixedly installed with an operating glove 4. Each fixing ring 3 has a detection component on one side that can quickly perform a sealing inspection on the operating glove 4 without removing it. Each detection component is equipped with a fixing component that can assist the detection component in quickly sealing and fixing with the adjacent fixing ring 3.

[0022] The detection assembly includes a sealing plate 501 that is fitted to one side of the fixing ring 3. A pressure sensor 502 for detecting the internal pressure of the operating glove 4 is fixedly installed on the sealing plate 501. An air inlet pipe 503 for injecting air into the operating glove 4 is fixedly connected to one side of the sealing plate 501.

[0023] The detection component can quickly verify the sealing performance of the operating glove 4 without disassembling the operating glove 4 by sealing the sealing plate 501 and the fixing ring 3 together with the air inlet pipe 503 inflation and the pressure sensor 502 detection; the fixing component can ensure the sealing reliability of the sealing plate 501 and the fixing ring 3, avoid air leakage during inflation, and solve the problems of low efficiency and poor sealing of the existing detection method.

[0024] An annular sealing groove is provided on the side of the fixing ring 3 near the sealing plate 501. An annular sealing strip 7 is fixedly installed on the side of the sealing plate 501 near the fixing ring 3. The annular sealing strip 7 is adapted to the annular sealing groove. A sealing ring 8 is fixedly installed on the side of the sealing plate 501 near the fixing ring 3. One side of the sealing ring 8 is in contact with one side of the fixing ring 3.

[0025] The sealing ring 8 can form a "double seal" on the basis of the annular sealing strip 7, further blocking the gas leakage path, which is especially suitable for high-pressure inflation test scenarios and improves the sealing redundancy of the test components.

[0026] A first connecting block 9 is fixedly installed on the cylindrical surface of the sealing plate 501. A second connecting block 10 is rotatably installed on one side of the first connecting block 9. One side of the second connecting block 10 is fixedly installed on one side of the pharmaceutical isolator body 1, for rotating and storing the sealing plate 501 when not in use.

[0027] The rotational engagement of the first connecting block 9 and the second connecting block 10 enables the sealing plate 501 to be "rotated and stored". When not being tested, the sealing plate 501 can be rotated away from the operating port 2 to avoid blocking the operating port 2 and affecting normal production operations, thereby improving the flexibility of equipment use.

[0028] The fixing assembly includes locking blocks 601 fixedly installed on both sides of the fixing ring 3. The sealing plate 501 has fixing strips 602 with “T”-shaped sliding grooves fixedly installed on both sides. The interior of the two sliding grooves has a third connecting block 603 slidably installed. The two third connecting blocks 603 have a hook plate 604 fixedly installed on one side. The two hook plates 604 are adapted to the adjacent locking blocks 601. The two hook plates 604 and the two locking blocks 601 are inclined in a mutually adapted manner to facilitate the hook plates 604 hooking the adjacent locking blocks 601.

[0029] The "T"-shaped sliding groove and the third connecting block 603 can restrict the hook plate 604 to slide only in the horizontal direction; the hook plate 604 and the inclined surface of the locking block 601 are adapted to achieve "quick engagement", and the initial fixing of the sealing plate 501 can be completed without complicated operation, improving the preparation efficiency before testing. When it is necessary to open the sealing plate 501, it is only necessary to slide the hook plate 604 to separate it from the locking block 601.

[0030] A first fixing plate 11 is fixedly installed on the cylindrical surface of the sealing plate 501. A second fixing plate 12 is provided on one side of the first fixing plate 11 and fixedly installed with the fixing ring 3. A threaded post 13 is provided on the other side of the first fixing plate 11. One end of the threaded post 13 is on the first fixing plate 11 and extends into the interior of the second fixing plate 12. The threaded post 13 is threadedly engaged with the second fixing plate 12. A rotating block is fixedly installed on the other end of the threaded post 13.

[0031] Rotating the threaded column 13 can drive the first fixed plate 11 to move closer to the second fixed plate 12 through the threaded engagement, thereby pushing the sealing plate 501 to fit tightly with the fixed ring 3, ensuring that the annular sealing strip 7 is fully embedded in the annular sealing groove, achieving "precise pressure sealing" and avoiding uneven sealing caused by manual pressing.

[0032] The implementation principle of a novel high-sealing pharmaceutical isolator in this application embodiment is as follows: In the initial state, the sealing plate 501 is stored on the side away from the operation port 2 through the rotational cooperation of the first connecting block 9 and the second connecting block 10, which does not affect the normal use of the operating gloves 4. The hook plate 604 is located at one end of the sliding groove in cooperation with the third connecting block 603. When it is necessary to perform a sealing test on the operating glove 4, the operator first holds the edge of the sealing plate 501 and rotates the sealing plate 501 towards the fixing ring 3 with the second connecting block 10 as the rotation axis until the sealing ring 8 on one side of the sealing plate 501 fits against the side of the fixing ring 3, and the annular sealing strip 7 on the sealing plate 501 is aligned with the annular sealing groove of the fixing ring 3.

[0033] During this process, after the inclined surface of the hook plate 604 contacts the inclined surface of the locking block 601, under the continuous pushing force, the hook plate 604 slides along the inclined surface into the underside of the locking block 601 until the hook plate 604 is completely engaged with the locking block 601, thus completing the initial fixing of the sealing plate 501.

[0034] Subsequently, the operator holds the rotating block at the end of the threaded column 13 and rotates the threaded column 13 clockwise. Since the threaded column 13 is threadedly engaged with the second fixed plate 12 and the second fixed plate 12 is fixedly connected to the fixed ring 3, the threaded column 13 will move towards the second fixed plate 12 when rotated clockwise. When the threaded column 13 moves, its end pushes the first fixed plate 11 towards the fixed ring 3, thereby driving the sealing plate 501 to move synchronously. During the movement of the sealing plate 501, the annular sealing strip 7 on one side gradually embeds into the annular sealing groove of the fixed ring 3. At the same time, the contact pressure between the sealing ring 8 and the fixed ring 3 increases until the rotation of the threaded column 13 feels obvious resistance. At this time, the annular sealing strip 7 is completely embedded in the sealing groove, the sealing ring 8 is tightly attached to the fixed ring 3, the rotation of the threaded column 13 stops, and the sealing and fixing of the sealing plate 501 and the fixed ring 3 is completed.

[0035] After sealing and fixing, the operator connects the air inlet pipe 503 to an external clean compressed air source and opens the air valve to inflate the inside of the operating glove 4: air enters the inside of the operating glove 4 through the air inlet pipe 503, and the operating glove 4 gradually expands; at the same time, the pressure sensor 502 on the sealing plate 501 detects the internal pressure of the operating glove 4 in real time and transmits the data to the external display terminal; when the pressure reaches the preset value, the air valve is closed and the pressure is maintained for 5-10 minutes.

[0036] During the pressure holding process, if the pressure sensor 502 detects no pressure drop, it indicates that the operating glove 4 is undamaged and its sealing performance is qualified; if the pressure drops, it indicates that there is a leak in the operating glove 4, which requires further investigation. After the test is completed, the operator rotates the threaded column 13 counterclockwise to separate the sealing plate 501 from the fixing ring 3, and then pulls the hook plate 604 to slide in the sliding groove with the third connecting block 603 to disengage from the locking block 601. Finally, the sealing plate 501 is rotated and stored to complete a single test.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
