Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a sterile testing isolator. Background Technology

[0002] Sterility testing is a critical quality control step for the release of pharmaceuticals, medical devices, and biological products. Its purpose is to confirm the presence of live microorganisms in the product. This testing process must be carried out in a strictly sterile environment to prevent external microbial contamination of the sample, which could lead to false positive results and incorrectly determine qualified products as unqualified, resulting in significant economic losses and resource waste.

[0003] However, in the existing technology, when operators take the test samples from inside the transfer chamber through the sterile chamber, the obstruction of the glass makes it difficult for them to take the samples due to obstructed vision or inconvenient operation, which affects the testing efficiency and may even increase the risk of the test samples falling due to repeated attempts. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sterile testing isolator to solve the problem of inconvenient handling of test samples in the prior art.

[0005] The present invention provides the following technical solution: a sterile testing isolator, comprising an isolator body, wherein a sterile chamber and a transfer chamber are respectively opened inside the isolator body, and a partition wall is provided between the sterile chamber and the transfer chamber. A sealing door for separating the transfer chamber and the sterile chamber is installed on one side surface of the partition wall. An auxiliary transfer assembly for transferring the test sample from the transfer chamber is provided inside the sterile chamber. The auxiliary transfer assembly includes a first placement plate disposed inside the sterile chamber and a second placement plate disposed inside the transfer chamber.

A constant speed assembly for keeping the moving speed of the first placement plate stable is provided inside the sterile chamber.

[0006] As a further embodiment of the present invention, the auxiliary transfer assembly further includes two first positioning blocks symmetrically arranged inside the sterile cavity. The first placement plate is located between the two first positioning blocks. Two first guide rails are symmetrically fixedly connected to both sides of the first placement plate. The two first guide rails are respectively located inside the two first positioning blocks. A plurality of first sliders are equidistantly fixedly connected to the interior of each first positioning block. The first guide rails are slidably connected to the first sliders. Two second positioning blocks are symmetrically fixedly connected inside the transfer cavity. The second placement plate is located between the two second positioning blocks. Second guide rails are symmetrically fixedly connected to both sides of the second placement plate. The second guide rails are located inside the second positioning blocks. A second slider is fixedly connected to the interior of each second positioning block. The second slider is slidably connected to the second guide rail. A first magnetic block and a second magnetic block are respectively provided on the side adjacent to the first placement plate and the second placement plate. The first magnetic block and the second magnetic block are magnetically connected.

[0007] As a further embodiment of the present invention, the second placement plate and the first placement plate are respectively located on both sides of the partition wall, and the width of the first placement plate and the second placement plate is smaller than the width of the transfer hole in the partition wall.

[0008] As a further embodiment of the present invention, a positioning box is fixedly connected to the bottom surface of the first placement plate near the second placement plate, the second magnetic block is disposed inside the positioning box and slidably connected to the positioning box, and the first magnetic block is fixedly connected to the bottom surface of the second placement plate at a position opposite to the second magnetic block.

[0009] As a further embodiment of the present invention, the two sides of the second magnetic block are respectively rotatably connected to a pull rod via a bearing seat. The bearing seat passes through the positioning box and is slidably connected to the positioning box. The top surface of the first placement plate is symmetrically and fixedly connected to two positioning seats. A force-applying rod is slidably connected to the surface of the positioning seat. The force-applying rod is rotatably connected to the pull rod via a positioning shaft.

[0010] As a further embodiment of the present invention, the folding assembly includes four positioning bearing seats that are evenly distributed and fixedly connected inside the sterile cavity, and the four positioning bearing seats are respectively located on both sides of the first placement plate, and each positioning bearing seat is rotatably connected to a linkage rod inside, the linkage rod being rotatably connected to the first positioning block through a positioning shaft.

[0011] As a further embodiment of the present invention, the partition wall has two slots symmetrically fixedly connected on the side near the first placement plate, and the first positioning block is fixedly connected with irregularly shaped inserts at positions opposite to the slots. The irregularly shaped inserts are inserted into the slots, and the slots have contoured grooves with the same shape as the irregularly shaped inserts inside.

[0012] As a further embodiment of the present invention, the uniform speed component includes a first positioning rail fixedly connected to the bottom surface of each of the first positioning blocks, and a damping pulley fixedly connected to the bottom surface of the first placement plate by bolts. The damping pulley is inserted inside the first positioning rail and rolls inside the first positioning rail.

[0013] As a further embodiment of the present invention, two dampers are symmetrically installed on the bottom surface of the first placement plate near the side of the second placement plate, and baffles are fixedly connected to the bottom surface of the second placement plate at positions opposite to the dampers, with the force-bearing end of the damper in contact with the baffle.

[0014] As a further embodiment of the present invention, the surface of the second placement plate is provided with a limiting component for limiting the detection item. The limiting component includes a plurality of positioning sliding holes evenly opened along the axis on the surface of the second placement plate. Each positioning sliding hole has two limiting posts symmetrically slidably connected inside, and the positioning sliding hole is formed by multiple positioning holes connected by positioning grooves.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention achieves a smooth and stable transfer of test samples between the transfer chamber and the sterile chamber through an auxiliary transfer component, replacing traditional manual or robotic operation, improving transfer efficiency and reducing the risk of contamination.

[0016] 2. This invention achieves automatic docking of the first and second placement plates by utilizing the magnetic attraction between the first and second magnetic blocks. The sliding second magnetic block design buffers the impact force during magnetic attraction, preventing displacement or leakage of the sample due to vibration, making it particularly suitable for liquid samples.

[0017] 3. By setting up a structure that links the force-applying rod and the pull rod, the second magnetic block can be retracted through a simple operation when the placement plate needs to be separated, quickly releasing the magnetic connection and facilitating the reset of the second placement plate. The operation is convenient and highly reliable.

[0018] 4. The folding assembly of the present invention, through the cooperation of the linkage rod and the bearing seat, enables the first placement plate and the first positioning block to move and fold as a whole away from the partition wall, effectively saving the internal space of the sterile chamber and improving the space utilization rate of the equipment.

[0019] 5. The present invention utilizes the contour groove design of the irregularly shaped plug and the slot to achieve a self-locking effect after insertion by taking advantage of the toughness of the composite plastic, ensuring that the first positioning block is firmly connected to the partition wall in the unfolded state and preventing shaking during use.

[0020] 6. The present invention provides a damping pulley and a first positioning rail at the bottom of the first placement plate. By utilizing the rolling characteristics of the damping pulley, the first placement plate maintains a uniform speed during movement, thus avoiding shaking or tipping of the test item due to sudden speed changes.

[0021] 7. The present invention provides a damper on the bottom surface of the first placement plate and a baffle at the corresponding position of the second placement plate, so that the two plates are buffered by the damper when they come into contact, thereby reducing the impact force and avoiding damage to the equipment structure and disturbance to the sample.

[0022] 8. The present invention uses a limiting post that can move within the positioning sliding hole to adjust its position according to the size of different test samples, and uses gravity self-locking to achieve fixation, effectively preventing the sample from sliding or tipping over during the transfer process, thus enhancing adaptability.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figures 1-14This invention provides a sterile testing isolator, including an isolator body 1. The isolator body 1 has a sterile chamber 3 and a transfer chamber 2 respectively opened inside, and a partition wall 4 is provided between the sterile chamber 3 and the transfer chamber 2. A sealing door for separating the transfer chamber 2 and the sterile chamber 3 is installed on one side surface of the partition wall 4. An auxiliary transfer component 5 for transferring the test sample from the transfer chamber 2 is provided inside the sterile chamber 3. The auxiliary transfer component 5 includes a first placement plate 52 disposed inside the sterile chamber 3 and a second placement plate 55 disposed inside the transfer chamber 2. A folding component 6 for folding and storing the first placement plate 52 is provided inside the sterile chamber 3. A constant speed component 7 for keeping the movement speed of the first placement plate 52 stable is provided inside the sterile chamber 3.

[0040] In this invention, the auxiliary transfer component 5 further includes two first positioning blocks 51 symmetrically arranged inside the sterile chamber 3, a first placement plate 52 located between the two first positioning blocks 51, two first guide rails 53 symmetrically fixedly connected to both sides of the first placement plate 52, the two first guide rails 53 respectively located inside the two first positioning blocks 51, a plurality of first sliders 54 are symmetrically fixedly connected laterally inside each first positioning block 51, the first guide rails 53 and the first sliders 54 are slidably connected, two second positioning blocks 56 are symmetrically fixedly connected inside the transfer chamber 2, a second placement plate 55 is located between the two second positioning blocks 56, and a second guide rail 57 is symmetrically fixedly connected to both sides of the second placement plate 55, the second guide rails 57 are located inside the second positioning blocks 56, a second slider 58 is fixedly connected inside each second positioning block 56, the second slider 58 and the second guide rail 57 are slidably connected, a first magnetic block 59 and a second magnetic block 511 are respectively arranged on the adjacent side of the first placement plate 52 and the second placement plate 55, and the first magnetic block 59 and the second magnetic block 511 are magnetically connected.

[0041] The second placement plate 55 and the first placement plate 52 are located on both sides of the partition wall 4, and the width of the first placement plate 52 and the second placement plate 55 is smaller than the width of the transfer hole in the partition wall 4.

[0042] When placing the test sample inside the transfer chamber 2 for transfer, first open the outer door of the transfer chamber 2. Before opening the outer door, ensure that the sealing door is completely closed. Then place the test sample in the positioning position of the second placement plate 55, and then close the outer door of the transfer chamber 2. Then, sterilize the inside of the transfer chamber 2 through the internal equipment of the isolator body 1. Afterwards, the operator opens the sealing door. Before opening the sealing door, ensure that the outer door is closed and that the inside of the isolator body 1 is sterile. After the sealing door is opened, apply force to the first placement plate 52 towards the transfer chamber 2. The first placement plate 52 will slide on the surface of the first slider 54 via the first guide rail 53, thereby moving the first placement plate 52 inside the first positioning block 51 until one end of the first placement plate 52 passes through the transfer hole and is connected to the second positioning block 55. When the placement plates 55 are in contact with each other, the second magnetic block 511 will attract the first magnetic block 59, thus limiting the second placement plate 55. Then, when the first placement plate 52 is pulled in the opposite direction, the second placement plate 55 will slide on the surface of the second slider 58 due to magnetic attraction via the second guide rail 57. This allows the second placement plate 55 to move inside the second positioning block 56 toward the sterile chamber 3 until the second placement plate 55 passes through the transfer door. The second guide rail 57 will then insert into the inside of the first slider 54, achieving uninterrupted movement and moving the test sample into the sterile chamber 3. This makes it convenient for operators to pick up the test sample, allowing the auxiliary transfer component 5 to act as a robotic arm, taking the test sample from inside the transfer chamber 2 to inside the sterile chamber 3.

[0043] During the above operation, the uniform speed component 7 ensures that the speed of the first placement plate 52 remains stable during movement, preventing any impact on the transfer of the test sample due to excessively fast or slow speeds, thus effectively improving the stability and reliability of the transfer. Simultaneously, the folding component 6 allows the first placement plate 52 to be folded and stored when not in use, significantly saving space inside the sterile chamber 3 and making the overall structure of the device more compact and rational. Furthermore, through a series of ingenious structural designs, such as the sliding connection between the first guide rail 53 and the first slider 54, the sliding connection between the second guide rail 57 and the second slider 58, and the magnetic connection between the first magnetic block 59 and the second magnetic block 511, the device achieves stable and smooth transfer of the test sample between the transfer chamber 2 and the sterile chamber 3, providing great convenience for related operations and demonstrating high practical value and application prospects.

[0044] In this invention, a positioning box 510 is fixedly connected to the bottom surface of the first placement plate 52 near the second placement plate 55, a second magnetic block 511 is disposed inside the positioning box 510 and slidably connected to the positioning box 510, and a first magnetic block 59 is fixedly connected to the bottom surface of the second placement plate 55 at a position opposite to the second magnetic block 511.

[0045] The second magnetic block 511 has a pull rod 512 rotatably connected to both sides of the bearing seat. The bearing seat passes through the positioning box 510 and is slidably connected to the positioning box 510. The top surface of the first placement plate 52 is symmetrically and fixedly connected to two positioning seats 514. The surface of the positioning seat 514 is slidably connected to a force rod 513. The force rod 513 is rotatably connected to the pull rod 512 through a positioning shaft.

[0046] When the first magnetic block 59 and the second magnetic block 511 are magnetically attracted, as the first placement plate 52 gradually approaches the second placement plate 55, the first magnetic block 59 will be inserted into the interior of the positioning box 510 until it reaches the magnetic attraction range. At this point, the second magnetic block 511 will move towards the first magnetic block 59 inside the positioning box 510. Because the connection between the first magnetic block 59 and the second placement plate 55 is relatively heavy, when the first magnetic block 59 and the second magnetic block 511 approach each other, the second magnetic block 511 will move towards the first magnetic block 59 inside the positioning box 510. The movable connection of the second magnetic block 511 can prevent the momentary pulling force during the attraction from causing the second placement plate 55 to shake, which would cause the test sample to move momentarily on the surface of the second placement plate 55 and cause the liquid test sample to leak.

[0047] When the sample is removed from the sterile chamber 3, and the second placement plate 55 needs to be pushed back to its original position, the force rod 513 is turned. The force rod 513 will slide on the surface of the positioning seat 514 through the waist hole. When the force rod 513 rotates, the pull rod 512 will be subjected to force and exert force on the second magnetic block 511, causing the second magnetic block 511 to slide into the positioning box 510 until it moves a certain distance. When the first magnetic block 59 and the second magnetic block 511 are no longer magnetic, the second placement plate 55 can be pushed back to its original position directly.

[0048] This design not only ensures the stability of the second placement plate 55 during magnetic attraction, effectively preventing side leakage of the test item, but also greatly improves operational convenience. When it is necessary to reset the second placement plate 55, simply prying the force application rod 513 will cause the second magnetic block 511 to slide inside the positioning box 510 through a series of mechanical linkages, thereby releasing the magnetic attraction between the first magnetic block 59 and the second magnetic block 511, allowing the second placement plate 55 to be easily pushed back to its original position. This design considers both stability and ease of operation, demonstrating the ingenuity and practicality of the mechanical design of this invention.

[0049] In this invention, the folding assembly 6 includes four positioning bearing seats 61 that are evenly distributed and fixedly connected inside the sterile cavity 3. The four positioning bearing seats 61 are located on both sides of the first placement plate 52, and each positioning bearing seat 61 is rotatably connected to a linkage rod 62. The linkage rod 62 is rotatably connected to the first positioning block 51 through a positioning shaft.

[0050] Two slots 63 are symmetrically fixedly connected to the side of the partition wall 4 near the first placement plate 52. The first positioning block 51 is fixedly connected to the slot 63 with a shaped plug 64 at the position opposite to the slot 63. The shaped plug 64 is inserted into the inside of the slot 63. The inside of the slot 63 is provided with a contour groove with the same shape as the shaped plug 64.

[0051] When the auxiliary transmission component 5 is folded, the first positioning block 51 moves away from the partition wall 4. When the first positioning block 51 moves away, the linkage rod 62 rotates inside the positioning bearing seat 61. The two linkage rods 62 on each side ensure that the first positioning block 51 remains parallel when it moves. When the first positioning block 51 moves away from the partition wall 4, the irregularly shaped insert 64 is pulled out from the slot 63. Due to the contour groove of the slot 63, the irregularly shaped insert 64 will deform to a certain extent when it is pulled out from the slot 63. Since the irregularly shaped insert 64 is a composite plastic with strong toughness, when the irregularly shaped insert 64 is inserted into the slot 63, the irregularly shaped insert 64 will limit the first positioning block 51 due to its shape and toughness.

[0052] Meanwhile, this design also ensures a stable connection between the first positioning block 51 and the partition wall 4 in the unfolded state. The irregularly shaped insert 64 is tightly inserted into the contoured groove of the slot 63. Utilizing the toughness and shape matching of the composite plastic, it effectively prevents the first positioning block 51 from shaking or shifting during use, ensuring the stability and reliability of the entire device structure. Moreover, this unique connection and limiting method eliminates the need for additional complex mechanical structures or excessive parts, simplifying the overall structure of the device, reducing production costs, and making the device more convenient and efficient to assemble and disassemble, greatly improving the ease of use and maintenance.

[0053] In this invention, the uniform speed component 7 includes a first positioning rail 71 fixedly connected to the bottom surface of each first positioning block 51, and a damping pulley 72 fixedly connected to the bottom surface of the first placement plate 52 by bolts. The damping pulley 72 is inserted inside the first positioning rail 71 and rolls inside the first positioning rail 71.

[0054] When the first placement plate 52 moves, the damping pulley 72 rolls inside the first positioning rail 71. Through the characteristics of the damping pulley 72, the first placement plate 52 will always maintain the same speed when moving, avoiding a situation of rushing and stopping during movement.

[0055] Utilizing the principle of rolling friction, compared to sliding friction, rolling friction significantly reduces the resistance during the movement of the first placement plate 52, making its movement smoother and more stable. Furthermore, because the damping pulley 72 rolls inside the first positioning rail 71, it also guides the movement direction of the first placement plate 52, further ensuring the accuracy of its movement. At the same time, this structure is simple, reliable, and less prone to failure, enabling stable operation over extended periods and providing strong support for the normal operation of the entire device.

[0056] In this invention, two dampers 8 are symmetrically installed on the bottom surface of the first placement plate 52 near the side of the second placement plate 55. Baffles are fixedly connected to the bottom surface of the second placement plate 55 at positions opposite to the dampers 8, and the force-bearing end of the damper 8 is in contact with the baffle.

[0057] When the first placement plate 52 and the second placement plate 55 come into contact with each other, the force-bearing end of the damper 8 will come into contact with the baffle. Due to its own characteristics, the damper 8 will make the contact between the first placement plate 52 and the second placement plate 55 slow, so as to avoid the first placement plate 52 and the second placement plate 55 from colliding.

[0058] In this invention, the surface of the second placement plate 55 is provided with a limiting component 9 for limiting the detection item; The limiting component 9 includes a plurality of positioning sliding holes 91 evenly opened along the axis on the surface of the second placement plate 55. Each positioning sliding hole 91 has two limiting posts 92 symmetrically slidably connected inside, and the positioning sliding hole 91 has multiple positioning holes connected by positioning grooves.

[0059] To prevent the test item from moving on the surface of the second placement plate 55, when the test item is placed on the top surface of the second placement plate 55, the limiting post 92 is lifted. Due to the shape of the limiting post 92, the limiting post 92 can move inside the positioning sliding hole 91 until the limiting post 92 and the test item are in contact. Then, the force applied to the limiting post 92 is released, and the limiting post 92 will insert into the positioning hole due to gravity, thereby limiting the limiting post 92 and thus limiting the test item.

[0060] The present invention is used in the following steps: S1: When placing the test sample inside the transfer chamber 2 for transfer, first open the outer door of the transfer chamber 2. Before opening the outer door, ensure that the sealing door is completely closed. Then place the test sample in the positioning position of the second placement plate 55, and then close the outer door of the transfer chamber 2. Then, sterilize the inside of the transfer chamber 2 through the internal equipment of the isolator body 1. Afterwards, the operator opens the sealing door. Before opening the sealing door, ensure that the outer door is closed and that the inside of the isolator body 1 is sterile. After the sealing door is opened, apply force to the first placement plate 52 towards the transfer chamber 2. The first placement plate 52 will slide on the surface of the first slider 54 through the first guide rail 53, thereby moving the first placement plate 52 inside the first positioning block 51 until one end of the first placement plate 52 passes through the transfer hole and is connected to the second positioning block 55. When the first placement plate 52 and the second placement plate 55 are in contact with each other, the second magnetic block 511 will be attracted to the first magnetic block 59, thus limiting the second placement plate 55. Then, when the first placement plate 52 is pulled in the opposite direction, the second placement plate 55 will slide on the surface of the second slider 58 due to magnetic attraction via the second guide rail 57, thereby moving the second placement plate 55 inside the second positioning block 56 toward the sterile chamber 3 until the second placement plate 55 passes through the transfer door. The second guide rail 57 will then be inserted into the inside of the first slider 54, achieving uninterrupted movement and moving the test sample into the sterile chamber 3, making it convenient for operators to pick up the test sample. This allows the auxiliary transfer component 5 to act as a robotic arm, picking up the test sample from the inside of the transfer chamber 2 to the inside of the sterile chamber 3. S2: When the first magnetic block 59 and the second magnetic block 511 are magnetically attracted, as the first placement plate 52 gradually approaches the second placement plate 55, the first magnetic block 59 will be inserted into the interior of the positioning box 510 until it reaches the magnetic attraction range. At this time, the second magnetic block 511 will move towards the first magnetic block 59 inside the positioning box 510. Because the connection between the first magnetic block 59 and the second placement plate 55 is relatively heavy, when the first magnetic block 59 and the second magnetic block 511 approach each other, the second magnetic block 511 will move towards the first magnetic block 59 inside the positioning box 510. The movable connection of the second magnetic block 511 can avoid the momentary pulling force during the attraction of the two magnetic blocks causing the second placement plate 55 to shake, causing the test sample to move instantaneously on the surface of the second placement plate 55, which may cause the liquid test sample to leak. S3: When the test sample enters the sterile chamber 3 and is removed, and the second placement plate 55 needs to be pushed back to its original position, the force rod 513 is turned. The force rod 513 will slide on the surface of the positioning seat 514 through the waist hole. When the force rod 513 rotates, the pull rod 512 will be subjected to force and exert force on the second magnetic block 511, causing the second magnetic block 511 to slide into the positioning box 510 until it moves a certain distance. When the first magnetic block 59 and the second magnetic block 511 are no longer magnetic, the second placement plate 55 can be pushed back to its original position directly. S4: When the auxiliary transmission component 5 is folded, the first positioning block 51 moves away from the partition wall 4. When the first positioning block 51 moves away, the linkage rod 62 will rotate inside the positioning bearing seat 61. The two linkage rods 62 on each side ensure that the first positioning block 51 remains parallel when it moves. When the first positioning block 51 moves away from the partition wall 4, the irregularly shaped insert 64 will be pulled out from the slot 63. Due to the contour groove of the slot 63, the irregularly shaped insert 64 will undergo a certain deformation when it is pulled out from the slot 63. The irregularly shaped insert 64 is a composite plastic with strong toughness. When the irregularly shaped insert 64 is inserted into the slot 63, the irregularly shaped insert 64 will limit the first positioning block 51 due to its shape and toughness. S5: When the first placement plate 52 is moving, the damping pulley 72 will roll inside the first positioning rail 71. Through the characteristics of the damping pulley 72, the first placement plate 52 will always maintain the same speed when moving, avoiding the situation of rushing and stopping during movement. S6. When the first placement plate 52 and the second placement plate 55 come into contact with each other, the force-bearing end of the damper 8 will come into contact with the baffle. Due to its own characteristics, the damper 8 will make the first placement plate 52 and the second placement plate 55 come into contact slowly, so as to avoid the first placement plate 52 and the second placement plate 55 from colliding. S7. To prevent the test item from moving on the surface of the second placement plate 55, when the test item is placed on the top surface of the second placement plate 55, the limiting post 92 is lifted. Due to the shape of the limiting post 92, the limiting post 92 can move inside the positioning sliding hole 91 until the limiting post 92 and the test item are in contact. Then, the force applied to the limiting post 92 is released, and the limiting post 92 will be inserted into the positioning hole due to gravity, thereby limiting the limiting post 92 and thus limiting the test item.
