Description

Technical Field

[0001] This utility model relates to the field of microbial barrier testing technology, specifically to a dry microbial barrier testing device. Background Technology

[0002] Breathable packaging materials used for sterilizing medical devices are typically supplied to medical institutions and medical device manufacturers. Due to differences in sterilization methods, transportation conditions, storage conditions, and shelf life, the requirements for their microbial barrier properties also vary.

[0003] Existing dry-method microbial barrier tests typically involve cutting the sample to a suitable size, placing it on top of a test bottle, then inserting a petri dish into the bottle, and finally adding the contaminated material on top of the sample. The operator then places the test bottle in a temperature suitable for colony growth for a period of time. After removing the bottle, the effectiveness of the microbial barrier is determined by analyzing the bacterial community in the petri dish. However, in practice, if temperature conditions need to be changed for different stages of cultivation, the entire space must be allowed to adjust. This not only consumes a significant amount of time and reduces experimental efficiency but may also negatively impact the accuracy and reliability of the test results because the cultivation environment deviates from its optimal state during temperature adjustment, thus affecting the experimental microbial community. Utility Model Content

[0004] This invention proposes a dry method test device for microbial barriers, which solves the problem in related technologies where the culture environment deviates from the optimal state during temperature adjustment, which may affect the test microbial community and thus the test results.

[0005] The technical solution of this utility model is as follows:

[0006] A dry method test apparatus for microbial barrier testing includes a dry method test bottle and an incubator, wherein the incubator includes:

[0007] The box has a holding space for holding the dry test bottle;

[0008] A lid is rotatably mounted on the box body, and the box lid can be rotated to open or close the holding space;

[0009] A partition is provided within the holding space to divide the holding space into a first space and a second space that are not connected to each other. Both the first space and the second space are equipped with temperature control devices and are used to hold the dry test bottles.

[0010] Optionally, the partition is rotatably disposed within the holding space, and after rotation, the partition isolates or connects the first space and the second space. The incubator further includes:

[0011] A lifting component is provided within the holding space. The lifting component is used to place the dry test bottle. After the lifting component is raised or lowered, it enters the first space or the second space.

[0012] A top rod is mounted on the lifting component. The top rod is used to drive the partition to rotate and connect the first space and the second space. The height of the top rod is higher than that of the dry test bottle.

[0013] Optionally, there are two partitions, which are rotatably disposed at opposite ends of the holding space. The rotation axes of the two partitions are parallel. After the two partitions rotate, the ends of the two partitions that are close to each other abut against each other. There are two push rods, which are both disposed on the lifting member. The two push rods are used to drive the two partitions to rotate and connect the first space and the second space.

[0014] Optionally, it also includes:

[0015] The first elastic element has two ends respectively disposed on the partition and the box body. The first elastic element is used to provide the force for the partition to rotate and separate the first space and the second space.

[0016] Optionally, the two partitions have beveled edges at their ends that are close to each other. After the beveled edges of the two partitions abut against each other, the first space and the second space are separated. The ends of the two top rods that are away from the lifting member are at different distances from the lifting member.

[0017] Optionally, the holding space is rectangular, and the four sides of the lifting component abut against the four sides of the holding space respectively. The first space is located above the second space. The box has a clearance groove located in the first space. One end of the partition is rotatably disposed in the clearance groove. After the partition is rotated, the other end enters or leaves the clearance groove.

[0018] Optionally, it also includes:

[0019] A heat insulation strip is provided at one end of the partition near the second space. After the lifting member rises, the lifting member abuts against the heat insulation strip.

[0020] Optionally, it also includes:

[0021] The second elastic element is disposed at both ends on the box body and the box lid respectively. The second elastic element is used to provide the force for the box lid to rotate and close the holding space.

[0022] Optionally, the dry test bottle includes:

[0023] The bottle body, which is used to hold the petri dish;

[0024] A first component is detachably mounted on the bottle body, and the first component has a first through hole communicating with the bottle body;

[0025] The second component is detachably mounted on the first component. The bottle body and the second component are located at opposite ends of the first component. The second component has a second through hole, the axis of which is collinear with the axis of the first through hole. The first component and the second component form a sample space for holding the sample.

[0026] A cap, detachably mounted on the second component, is used to close the second through hole.

[0027] Optionally, the first component and the bottle body, the second component and the cap are all connected by threads, and the first component and the second component are fastened together.

[0028] The working principle and beneficial effects of this utility model are as follows:

[0029] In this invention, the dry method test bottle can be used to place the cut sample and petri dish, and then bacterial powder is added on top of the sample. After completing the above operations, the operator can place the dry method test bottle into the incubator, where the storage space can be used to hold the dry method test bottle. When the door is open, it is convenient for the operator to place the dry method test bottle into the storage space; when the door is closed, the storage space is sealed, facilitating the maintenance of a constant temperature within the storage space.

[0030] A partition, made of heat-insulating material, is installed within the holding space and can be fixed or detached from the inner wall of the chamber. The partition divides the holding space into two separate, unconnected compartments. When the chamber door is closed, the first and second compartments are two independent, sealed spaces. Both compartments are equipped with temperature control devices, such as thermocouples or thermistors, allowing them to maintain different temperatures. After placing the sample and petri dishes in the dry-process test bottle, the operator can move the bottle to either the first or second compartment. When a different temperature environment is required after a period of incubation, the bottle can be moved directly to the other compartment. This not only prevents wasted time on temperature adjustments, improving experimental efficiency, but also avoids potential impacts on the test microbiota due to the petri dishes not being in optimal conditions during temperature adjustment, thus affecting the experimental results.

[0042] 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.

[0043] Reference Figures 1-6 This invention proposes a dry method test device for microbial barriers, including a dry method test bottle 100 and an incubator 200. The dry method test bottle 100 is used to hold the sample, and the incubator 200 is used to hold the dry method test bottle 100 and control the ambient temperature of the dry method test bottle 100. The incubator 200 includes a box body 210 with a holding space 211 for holding the dry method test bottle 100. A lid 220 is rotatably mounted on the box body 210, and the lid 220 opens or closes the holding space 211 after rotation. A partition 230 is disposed in the holding space 211, and the partition 230 is used to divide the holding space 211 into a first space 2111 and a second space 2112 that are not connected to each other. Both the first space 2111 and the second space 2112 have temperature control devices, and both the first space 2111 and the second space 2112 are used to hold the dry method test bottle 100.

[0044] In this embodiment, the dry test bottle 100 can be used to place the cut sample and petri dish, and then bacterial powder is added on top of the sample. After completing the above operations, the operator can place the dry test bottle 100 into the incubator 200, and the holding space 211 in the incubator 200 can be used to hold the dry test bottle 100. When the door is open, it is convenient for the operator to place the dry test bottle 100 into the holding space 211. When the door is closed, the holding space 211 can be sealed to facilitate the constant temperature inside the holding space 211.

[0045] A partition 230 is installed within the holding space 211. The partition 230 is made of heat-insulating material and can be installed on the inner wall of the enclosure 210 using methods such as fixed or detachable connection. The partition 230 divides the holding space 211 into a first space 2111 and a second space 2112 that are not interconnected. When the enclosure door is closed, the first space 2111 and the second space 2112 are two independent, sealed spaces. Both the first space 2111 and the second space 2112 are equipped with temperature control devices, which can be thermocouples or thermistors, etc. The two independent temperature control devices allow the first space 2111 and the second space 2112 to be at two different temperatures. After placing the sample and petri dish in the dry test bottle 100, the operator can put the dry test bottle 100 into the first space 2111 or the second space 2112. After a period of incubation, when different temperature environments are required, the operator can directly put the dry test bottle 100 into another space. This not only prevents the waste of time in temperature adjustment and improves experimental efficiency, but also avoids the possibility that the test microbial community may be affected during the temperature adjustment process because the petri dish is not in the optimal environment, thus affecting the experimental results.

[0046] Furthermore, the partition 230 is rotatably disposed within the holding space 211. After the partition 230 rotates, it isolates or connects the first space 2111 and the second space 2112. The incubator 200 also includes a lifting component 240, which is rotatably disposed within the holding space 211. The lifting component 240 is used to place the dry test bottle 100. After the lifting component 240 is rotatably disposed, it enters the first space 2111 or the second space 2112. The top rod 250 is disposed on the lifting component 240. The top rod 250 is used to drive the partition 230 to rotate and connect the first space 2111 and the second space 2112. The height of the top rod 250 is higher than that of the dry test bottle 100.

[0047] In this embodiment, the partition 230 is installed in the holding space 211 via a rotating shaft to achieve rotation. The rotating shaft should have good rotational flexibility and stability, and can be made of stainless steel and fixed to the inner wall of the housing 210 via bearings. The lifting component 240 can be a lifting platform driven by an electric push rod or a hydraulic push rod. Its surface should be flat and have a certain anti-slip performance to ensure the stable placement of the dry test bottle 100. The top rod 250 is fixed on the lifting component 240. Its position and height should not affect the placement of the dry test bottle 100, and should ensure that the top rod 250 contacts the partition 230 first during the lifting process of the lifting component 240, and drive the top rod 250 to rotate to connect the first space 2111 and the second space 2112, so that the dry test bottle 100 can be moved between the first space 2111 and the second space 2112 by the lifting of the lifting component 240. When it is necessary to move the lifting component 240 containing the dry test bottle 100 from one space to another, the lifting component 240 is activated to rise. During the ascent, the top rod 250 contacts the partition 230 and pushes the partition 230 to rotate, connecting the first space 2111 and the second space 2112, allowing the dry test bottle 100 to enter the other space.

[0048] The rotating design of the partition 230 and the lifting mechanism 240 enable the dry test bottle 100 to switch between two spaces within the holding space 211, avoiding the need for manual operation to open the lid 220, which could lead to external environmental influences on the temperature of the first space 2111 or the second space 2112. The cooperation between the top rod 250 and the lifting mechanism 240 enables the automatic opening and closing of the partition 230 without additional operating steps, thus improving testing efficiency.

[0049] Furthermore, there are two partitions 230, which are rotatably disposed at opposite ends of the holding space 211. The rotation axes of the two partitions 230 are parallel. After the two partitions 230 rotate, the ends of the two partitions 230 that are close to each other abut against each other. There are two push rods 250, which are both disposed on the lifting member 240. The two push rods 250 are used to drive the two partitions 230 to rotate and connect the first space 2111 and the second space 2112.

[0050] In this embodiment, both partitions 230 can be made of materials with high temperature resistance and good thermal insulation properties, such as ceramic fiberboard. Each partition 230 is mounted on the inner walls of opposite ends of the holding space 211 via its own pivot, and the pivot is firmly connected to the partition 230 to ensure smooth rotation. Two push rods 250 are symmetrically fixed on the lifting component 240. The position and height of the push rods 250 are precisely set to accurately contact the corresponding partition 230 and push it to rotate. The push rods 250 can be made of high-strength, high-rigidity metal materials, such as titanium alloy.

[0051] Furthermore, it also includes a first elastic element 260, with its two ends respectively disposed on the partition 230 and the housing 210. The first elastic element 260 is used to provide the force for the partition 230 to rotate and separate the first space 2111 and the second space 2112.

[0052] In this embodiment, the first elastic element 260 is a torsion spring. One end of the torsion spring is fixed to the partition 230 by a fixing pin or welding, and the other end is fixed to the inner wall of the housing 210. The specifications and parameters of the torsion spring are selected according to the rotation characteristics, weight, and required restoring torque of the partition 230. When the push rod 250 pushes the partition 230 to rotate, the torsion spring undergoes torsional deformation. After the push rod 250 descends, the torsion spring releases its stored energy, driving the partition 230 to rotate in the opposite direction, thereby achieving the function of separating the first space 2111 and the second space 2112.

[0053] Using torsion springs provides a compact and efficient restoring force, occupies little space, and does not affect the internal layout of the device. Torsion springs have good elastic stability and durability, maintaining reliable performance over long-term use and reducing maintenance requirements.

[0054] Furthermore, the two partitions 230 have inclined edges 231 at their ends that are close to each other. After the inclined edges 231 of the two partitions 230 abut against each other, the first space 2111 and the second space 2112 are separated. The ends of the two top rods 250 that are away from the lifting member 240 are at different distances from the lifting member 240.

[0055] In this embodiment, the ends of the two partitions 230 that are close to each other are processed into inclined sides 231. The angle and length of the inclined sides 231 should be reasonably designed according to the size of the partitions 230 and the partitioning requirements. When the partitions 230 rotate to abut each other, the two inclined sides 231 fit tightly together, thereby achieving effective partitioning of the first space 2111 and the second space 2112. In actual operation, when the lifting member 240 rises, the push rod 250 farther away from the lifting member 240 contacts and pushes the corresponding partition 230 to rotate first. As the lifting member 240 continues to rise, the other push rod 250 pushes its corresponding partition 230 to rotate, thereby realizing the sequential opening action of the two partitions 230. The two lifting members 240 have different heights, which allows the two partitions 230 to rotate sequentially, avoiding mutual interference caused by the abutment of the inclined sides 231 of the two partitions 230.

[0056] Furthermore, the holding space 211 is rectangular, and the four sides of the lifting component 240 abut against the four sides of the holding space 211 respectively. The first space 2111 is located above the second space 2112. The box body 210 has a clearance groove 2113, which is located in the first space 2111. One end of the partition 230 is rotatably disposed in the clearance groove 2113. After the partition 230 is rotated, the other end enters or leaves the clearance groove 2113.

[0057] In this embodiment, the holding space 211 has a rectangular structure, and the lifting component 240 is designed with a matching rectangular shape, its four sides tightly abutting against the four sides of the holding space 211. This not only ensures a smooth and wobbly lifting process but also provides heat insulation. After the partition 230 rotates to connect the first space 2111 and the second space 2112, the lifting mechanism continues to provide heat insulation, preventing excessive heat exchange between the first and second spaces 2111 and thus avoiding large temperature fluctuations. The first space 2111 is located above the second space 2112. The housing 210 has a clearance groove 2113 on the inner wall opposite to the first space 2111. The size of the clearance groove 2113 allows the partition 230 to rotate into it. One end of the partition 230 is mounted in the clearance groove 2113 via a pivot. The connection between the pivot and the clearance groove 2113 is secure, ensuring smooth rotation of the partition 230. When the partition 230 rotates, its other end can accurately enter or leave the clearance groove 2113. When the partition 230 rotates to connect the first space 2111 and the second space 2112, the partition 230 can enter the clearance groove 2113, preventing the partition 230 from affecting the rise of the lifting component 240. In actual operation, during the process of the lifting component 240 rising to the first space 2111, the top rod 250 pushes the partition 230 to rotate, and the free end of the partition 230 rotates towards the clearance groove 2113, opening the passage; when the lifting component 240 descends, the partition 230 rotates back under the action of the torsion spring or other elastic element, and the free end rotates again in the direction away from the clearance groove 2113, restoring the partition state.

[0058] The clearance groove 2113 provides reasonable space for the rotation of the partition 230, avoiding interference between the partition 230 and the internal structure of the housing 210 or the lifting component 240 during rotation, thus ensuring the normal operation of the device.

[0059] Furthermore, it also includes a heat insulation strip 270, which is disposed at one end of the partition 230 near the second space 2112. After the lifting member 240 rises, the lifting member 240 abuts against the heat insulation strip 270.

[0060] In this embodiment, the thermal insulation strip 270 can be made of a high-temperature resistant material with excellent thermal insulation performance, such as ceramic fiber strips or asbestos strips. The thermal insulation strip 270 is installed on the end of the partition 230 near the second space 2112 by means of adhesive bonding, inlay, or bolt fixing. The length of the thermal insulation strip 270 should match the width of the partition 230, and its width and thickness are selected according to actual thermal insulation requirements. During installation, it is essential to ensure that the thermal insulation strip 270 is firmly connected to the partition 230 and that its surface is flat. When the lifting component 240 rises, its top will tightly abut against the thermal insulation strip 270, forming an effective thermal insulation barrier.

[0061] The lifting component 240 can rise and drive the partition 230 to rotate via the top rod 250, connecting the first space 2111 and the second space 2112. The top rod 250 does not necessarily need to be in contact with the inner wall of the housing 210. After the top rod 250 drives the partition 230 to rotate, the partition 230 will not completely enter the clearance groove 2113; the partition 230 will be in an inclined state. After the lifting component 240 abuts against the heat insulation strip 270, heat loss from the first space 2111 through the partition 230 and the lifting component 240 can be prevented.

[0062] Furthermore, it also includes a second elastic member 280, with its two ends respectively disposed on the box body 210 and the box cover 220. The second elastic member 280 is used to provide the force for the box cover 220 to rotate and close the holding space 211.

[0063] In this embodiment, the second elastic element 280 is a torsion spring. One end of the torsion spring is fixed to the housing 210 by a fixing pin or welding, and the other end is fixed to the lid 220. The specifications and parameters of the torsion spring are selected based on the rotation characteristics, weight, and required closing torque of the lid 220. During installation, it is essential to ensure the torsion spring is precisely positioned so that it can provide sufficient and stable closing torque after the lid 220 is opened, allowing the lid 220 to smoothly return to the position of closing the holding space 211. When the lid 220 is opened, the torsion spring undergoes torsional deformation. When the external force applied to the lid 220 disappears, the torsion spring releases its stored energy, driving the lid 220 to rotate in the opposite direction, thus closing the holding space 211.

[0065] In this embodiment, the bottle body 110 can be made of transparent glass or high-temperature resistant plastic, and its shape is cylindrical to facilitate the containment of petri dishes. The first component 120 can be a ring-shaped structure, detachably mounted on the bottle body 110 by means of threaded connection or snap-fit ​​connection. The diameter of the first through hole 121 should be reasonably designed according to experimental requirements and the size of the bottle body 110. The second component 130 can also be ring-shaped and is mounted on the first component 120 by a similar detachable connection method. The diameter of the second through hole 131 matches that of the first through hole 121 to ensure smooth airflow and material flow. The cap 150 is detachably mounted on the second component 130 by means of thread or plug-in connection to ensure that the second through hole 131 can be tightly closed to prevent the entry of external substances.
