Description

[0001] This application is a divisional application of the invention entitled "Inflatable Membrane Structure Virus Detection Laboratory, Biosafety Laboratory, Soil-Covered Structure Virus Detection Laboratory", filed on April 16, 2020, with application number 202080004730.2. Technical Field

[0002] This application relates to the field of protective and isolation buildings, and more specifically, to an inflatable membrane structure virus testing laboratory. Background Technology

[0003] A biosafety laboratory is a laboratory built according to standardized laboratory design, configuration of experimental equipment, and use of personal protective equipment. Whenever a sudden outbreak of infectious disease or related event occurs, relevant samples collected on-site (including human, animal, and environmental samples) are quickly sent to the biosafety laboratory for detection and identification of potential biohazards (pathogens, toxins, etc.) to effectively support on-site scientific decision-making and rapid response.

[0004] Traditional virus testing laboratories mostly use conventional prefabricated building structures, requiring negative pressure systems to treat contaminated air. This leads to problems such as high implementation costs, long construction periods, difficulty in dismantling after completion, inability to pre-package and store materials, and difficulties in site selection. When a large-scale virus outbreak occurs, existing traditional virus testing laboratories or biosafety laboratories are clearly unable to meet the needs for flexible and timely deployment.

Detailed Implementation

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] Inflatable membrane structure building systems are innovative construction technologies that have been developed in recent years. They are fast to build, cost-effective, easy to store, have a high volume compression ratio, are quick to transport, facilitate resource allocation between cities, and can be readily produced and constructed on a large scale using existing production systems.

[0038] The following is combined with Figures 1-11 A detailed description of the inflatable membrane structure virus detection laboratory according to an embodiment of this application.

[0039] Reference Figures 1-3 As shown, the inflatable membrane structure virus detection laboratory according to the first aspect of this application may include: an inflatable membrane structure 1 that can be inflated to form a roof or tubular body, an inlet equipment integration module 5, and an outlet equipment integration module 6.

[0040] Reference Figures 2-3 As shown, the inflatable membrane structure 1 forms a functional space 19 after inflation, allowing laboratory personnel to perform virus testing and other auxiliary tasks (such as changing protective clothing) within this space. The inflatable membrane structure 1 takes shape quickly upon inflation, facilitating the rapid construction of the functional space 19. For areas with high testing volumes, using a rapidly assembling inflatable membrane structure virus testing laboratory can significantly alleviate testing pressure in a short time. Furthermore, the inflatable membrane structure 1 can be dismantled after deflation, freeing up space after the testing tasks are completed.

[0041] Reference Figures 2-3 As shown, the functional space 19 includes a clean area 2, a high-contamination area 4, and one or more buffer units 3. The buffer unit 3 is used as an auxiliary functional area, for example, changing protective clothing can be done in the buffer unit 3; the high-contamination area 4 is used as the main functional area, for example, sample reception, preparation, amplification, etc. can all be performed in the high-contamination area 4.

[0042] Reference Figure 3 As shown, the buffer unit 3 is defined by the inflatable membrane structure 1. The buffer unit 3 separates the clean area 2 from the high-contamination area 4, and the buffer unit 3 has an inner opening and closing door 33 that provides airtight isolation or communication with the clean area 2 and the high-contamination area 4. This achieves physical isolation between the three areas: the clean area 2, the buffer unit 3, and the high-contamination area 4.

[0043] like Figures 1-3 As shown, the entrance equipment integration module 5 is located at one end of the functional space 19, and the entrance equipment integration module 5 includes at least an entrance door 51, which is airtightly isolated from or connected to the clean area 2.

[0044] In a specific embodiment, the entrance door 51 can be a single-layer door. When the entrance door 51 is open, the clean area 2 can be connected to the outside world; when the entrance door 51 is closed, the clean area 2 can be isolated from the outside world.

[0045] In some alternative embodiments, the entrance door 51 can be a double door, comprising an inner door and an outer door. In this case, the entrance door 51 can be configured as an intelligent interactive entrance door, such as a light-interactive entrance door, enabling the inner and outer doors to intelligently interlock, meaning that the inner and outer doors are set to not be opened simultaneously, thereby isolating the clean area 2 from the outside world. For example, when the inner door of the entrance door 51 is open and the outer door is closed, the internal space of the entrance door 51 is connected to the clean area 2 but isolated from the outside world; when the outer door of the entrance door 51 is open and the inner door is closed, the internal space of the entrance door 51 is connected to the outside world but isolated from the clean area 2.

[0046] like Figures 1-3 As shown, the outlet equipment integration module 6 is located at the other end of the functional space 19, and the outlet equipment integration module 6 includes at least a waste transfer box 61. Waste generated in the functional space 19 can be transferred to the outside through the waste transfer box 61 after sterilization.

[0047] At least one of the inlet equipment integration module 5 and the outlet equipment integration module 6 also includes a bidirectional heat exchange fresh air fan with a filter. The bidirectional heat exchange fresh air fan is used to supply gas to or extract gas from the functional space 19. That is, the bidirectional heat exchange fresh air fan can perform both air extraction and supply functions. The number of bidirectional heat exchange fresh air fans can be set to multiple, and the working modes can also be combined in various ways. For example, when some bidirectional heat exchange fresh air fans extract gas from the functional space 19, other bidirectional heat exchange fresh air fans supply gas to the functional space 19; or all bidirectional heat exchange fresh air fans simultaneously supply gas to the functional space 19 for a period of time, and then switch to simultaneously extracting gas from the functional space 19, and the gas supply and gas extraction actions can be alternated.

[0048] Through the air extraction and supply actions of the bidirectional heat exchange fresh air unit, a directional airflow can be formed inside the functional space 19. The bidirectional heat exchange fresh air unit is equipped with a filter device, which can ensure that the air inlet and outlet are filtered efficiently, preventing dust, particles and other substances in the outside air from being brought into the functional space 19, and also preventing viruses in the functional space 19 from being brought to the outside, thus ensuring a high level of safety in the use of the inflatable membrane structure virus detection laboratory.

[0049] By using a two-way heat exchange fresh air system, a negative pressure environment can be created in the high-pollution zone 4. For example, when the amount of gas supplied by the two-way heat exchange fresh air system to the high-pollution zone 4 is less than the amount of gas extracted from the high-pollution zone 4, the high-pollution zone 4 will be under negative pressure. By setting the high-pollution zone 4 to a negative pressure environment, the spread of pathogenic microorganisms from the high-pollution zone 4 to the external environment can be effectively prevented.

[0050] In some alternative embodiments, the amount of gas delivered by the bidirectional heat exchange fresh air unit to the high-pollution zone 4 may be greater than the amount of gas extracted by the bidirectional heat exchange fresh air unit from the high-pollution zone 4. In this case, the high-pollution zone 4 is a positive pressure environment.

[0051] Optionally, the filtration device can be a multi-layer HEPA (High Efficiency Particulate Air Filter) filter. HEPA filters meet HEPA standards, achieving an efficiency of 99.7% for particles of 0.1 microns and 0.3 microns. A key characteristic of HEPA filters is that air can pass through, but tiny particles cannot. It can remove particles with a diameter of 0.3 microns or larger (1 / 200th the diameter of a human hair) with an efficiency exceeding 99.97%, making it the most effective filtration medium for pollutants such as smoke, dust, and bacteria. HEPA filters are available in five materials: PP filter paper, glass fiber, composite PP / PET filter paper, meltblown polyester nonwoven fabric, and meltblown glass fiber. Features: high air resistance, large dust holding capacity, high filtration accuracy, and can be processed into various sizes and shapes according to customer needs to suit different models.

[0052] According to the embodiments of this application, the inflatable membrane structure virus detection laboratory, by setting up an inlet equipment integration module 5 and an outlet equipment integration module 6, can realize the modular design of the inflatable membrane structure virus detection laboratory. The equipment on the inlet side is integrated into the inlet equipment integration module 5, and the equipment on the outlet side is integrated into the outlet equipment integration module 6, which is conducive to centralized management of equipment. The laboratory has a simple and beautiful appearance. Moreover, the inflatable membrane structure 1 can form a roof or tubular body by inflation, which is conducive to the rapid construction of the inflatable membrane structure virus detection laboratory, greatly shortening the time from construction to use, and enabling the inflatable membrane structure virus detection laboratory to be put into use as soon as possible. In addition, the high-contamination area 4 is a negative pressure environment, which is conducive to ensuring the safety of use when detecting viruses and enabling the laboratory to meet the corresponding biosafety level specifications.

[0053] In some embodiments, the high-contamination zone 4, the buffer unit 3, and the clean zone 2 are all negative pressure environments. That is, the functional space 19 is a negative pressure environment. In this way, when the entrance door 51 is opened and the clean zone 2 is connected to the outside, air only flows from the outside to the clean zone 2, while the air in the clean zone 2 does not flow to the outside. This is beneficial to improving the safety performance of the inflatable membrane structure virus detection laboratory.

[0054] A pressure difference is created between clean zone 2, buffer unit 3, and high-contamination zone 4. The pressure relationship among these zones is: clean zone 2 > buffer unit 3 > high-contamination zone 4, meaning the negative pressure in clean zone 2 is the weakest, and the negative pressure in high-contamination zone 4 is the strongest. This ensures that when clean zone 2 is connected to buffer unit 3, air flows only from the weaker negative pressure zone 2 to buffer unit 3, preventing air from flowing from buffer unit 3 to clean zone 2 and thus contaminating it. Similarly, when buffer unit 3 is connected to high-contamination zone 4, air flows only from the weaker negative pressure zone 3 to high-contamination zone 4, preventing air from flowing from high-contamination zone 4 to buffer unit 3 and thus contaminating it. The strongest negative pressure in high-contamination zone 4 effectively prevents the spread of pathogenic microorganisms from within it, further enhancing the safety of the inflatable membrane structure virus detection laboratory.

[0055] Reference Figure 2 As shown, the inflatable membrane structure virus detection laboratory may also include: at least one air column duct 71 with one end extending into the functional space 19, and the other end of the air column duct 71 connected to a corresponding bidirectional heat exchange fresh air unit.

[0056] Furthermore, the air column duct 71 has a first duct opening connecting to the clean area 2, a second duct opening connecting to the buffer unit 3, and a third duct opening connecting to the high-pollution area 4. When the bidirectional heat exchange fresh air unit is working, it can supply gas to the corresponding clean area 2, buffer unit 3, and high-pollution area 4 through the first duct opening, second duct opening, and third duct opening on the air column duct 71, or extract gas from the corresponding clean area 2, buffer unit 3, and high-pollution area 4.

[0057] Each air column duct 71 corresponds to a bidirectional heat exchange fresh air unit.

[0058] In this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0059] exist Figures 1-2 In one embodiment, the bidirectional heat exchange fresh air unit may include: an inlet-side bidirectional heat exchange fresh air unit 52 belonging to the inlet equipment integration module 5 and an outlet-side bidirectional heat exchange fresh air unit 62 belonging to the outlet equipment integration module 6. For example... Figure 2As shown, the inlet-side bidirectional heat exchange fresh air unit 52 is connected to the inlet-side air column duct 71, and the outlet-side bidirectional heat exchange fresh air unit 62 is connected to the outlet-side air column duct 71.

[0060] In some embodiments, the inlet-side bidirectional heat exchange fresh air fan 52 can be configured to supply gas to the functional space 19, and the outlet-side bidirectional heat exchange fresh air fan 62 can be configured to extract gas from the functional space 19. Multiple inlet-side bidirectional heat exchange fresh air fans 52 and outlet-side bidirectional heat exchange fresh air fans 62 can be configured to improve the efficiency of gas extraction and supply.

[0061] Furthermore, at least one of the inlet equipment integration module 5 and the outlet equipment integration module 6 also includes an outdoor air conditioning unit, and an indoor air conditioning unit 72 is installed within the functional space 19. The outdoor air conditioning unit and the indoor air conditioning unit 72 constitute an air conditioning system to regulate the temperature within the functional space 19.

[0062] Specifically, such as Figures 1-2 As shown, the outdoor air conditioning unit includes: an inlet-side outdoor air conditioning unit 53 belonging to the inlet equipment integration module 5 and an outlet-side outdoor air conditioning unit 63 belonging to the outlet equipment integration module 6.

[0063] Furthermore, the entrance equipment integration module 5 also includes: an entrance equipment rack 54, on which the entrance-side air conditioning outdoor unit 53 and the entrance-side bidirectional heat exchange fresh air unit 52 are placed.

[0064] like Figure 2 As shown, the entrance equipment integration module 5 also includes a disinfection wastewater tank 55, which is placed on the entrance equipment rack 54. The entrance equipment rack 54 can be constructed as a multi-layer support, thereby allowing the entrance-side air conditioning outdoor unit 53, the entrance-side bidirectional heat exchange fresh air unit 52, and the disinfection wastewater tank 55 to be arranged in layers. For example, the entrance-side bidirectional heat exchange fresh air unit 52 can be placed on the top layer to facilitate its connection with the air column duct 71; the disinfection wastewater tank 55, being heavier, can be placed on the bottom layer to ensure better stability. Simultaneously, the layered arrangement also helps save space and further realizes the integrated design of the laboratory.

[0065] Optionally, the entrance door 51 is an intelligent interactive entrance door, and it opens and closes in a contactless manner. This allows personnel to enter and exit the entrance door 51 without physical contact. In some optional embodiments, the entrance door 51 can be a light-interactive entrance door, using a mobile phone flash or flash ring to issue open or close commands. In other optional embodiments, the entrance door 51 can also be a voice-interactive entrance door, using voice commands to open or close it. This ensures that even when personnel are wearing protective clothing, contactless control of the entrance door 51 can be achieved without facial scanning.

[0066] like Figure 2 As shown, the outlet equipment integration module 6 also includes: an outlet equipment rack 64, on which the waste transfer box 61, the outlet-side air conditioning outdoor unit 63, and the outlet-side bidirectional heat exchange fresh air unit 62 are placed. The outlet equipment rack 64 can be constructed as a multi-layer support, thereby allowing the waste transfer box 61, the outlet-side air conditioning outdoor unit 63, and the outlet-side bidirectional heat exchange fresh air unit 62 to be arranged in layers. For example, the outlet-side bidirectional heat exchange fresh air unit 62 can be arranged on the top layer to facilitate its connection with the air column duct 71; the waste transfer box 61, due to its frequent use, can be arranged on the bottom layer to prevent waste passing through the waste transfer box 61 from falling onto the outlet-side air conditioning outdoor unit 63 and the outlet-side bidirectional heat exchange fresh air unit 62. Simultaneously, the layered arrangement also helps save space and further realizes the integrated design of the laboratory.

[0067] Reference Figures 2-3 , Figure 8 As shown, the export equipment integration module 6 also includes a fire escape emergency door 65, which is airtightly isolated from or connected to the high-pollution zone 4. In the event of a dangerous situation in the high-pollution zone 4, personnel can quickly escape through the fire escape emergency door 65. The escape flow is as follows: Figure 8 The B-stream is shown in the diagram.

[0068] In some embodiments, at least one area of ​​the clean area 2, buffer unit 3, and high-contamination area 4 is equipped with a smoke alarm system. For example, a smoke alarm system can be installed in the high-contamination area 4, or smoke alarm systems can be installed in all three areas: clean area 2, buffer unit 3, and high-contamination area 4. By equipping the clean area with a smoke alarm system, a warning function can be provided in the event of a fire in the laboratory, thereby improving the fire safety performance of the air-supported membrane structure virus detection laboratory and ensuring its safe use.

[0069] In some embodiments, at least one area of ​​the clean area 2, buffer unit 3, and high-contamination area 4 is equipped with a dry powder fire extinguisher. For example, a dry powder fire extinguisher can be installed in the high-contamination area 4, or dry powder fire extinguishers can be installed in all three areas: clean area 2, buffer unit 3, and high-contamination area 4. By equipping the clean area with dry powder fire extinguishers, small fires can be extinguished, preventing the spread of fire and further improving the fire safety performance of the air-supported membrane structure virus detection laboratory, ensuring its safe use.

[0070] like Figure 3 As shown, one or more air disinfection devices 73 are installed in the high-pollution zone 4. The air disinfection device 73 includes any one or more combinations of a plasma sterilizer, an ultraviolet ozone generator, and a dry fog hydrogen peroxide sterilizer. By installing the air disinfection device 73, the content of harmful air in the high-pollution zone 4 can be reduced, thereby ensuring the personal safety of laboratory personnel in the high-pollution zone 4. The air disinfection device 73 can be an ultraviolet vehicle, allowing it to move freely within the high-pollution zone 4 to disinfect the air in various areas.

[0071] like Figure 3 As shown, the buffer unit 3 includes: a first changing room 31 and a second changing room 32 that are independent of each other, and both the first changing room 31 and the second changing room 32 have an inward opening door 33.

[0072] Furthermore, such as Figure 3 , Figure 8 As shown, an entrance passage is formed between entrance door 51, the inner opening door 33 between the first changing room 31 and the clean area 2, and the inner opening door 33 between the first changing room 31 and the high-contamination area 4. An exit passage is formed between the inner opening door 33 between the second changing room 32 and the high-contamination area 4, the inner opening door 33 between the second changing room 32 and the clean area 2, and entrance door 51. The personnel flow in the air-supported membrane structure virus detection laboratory can be as follows: Figure 8 As shown by the A-flow line, the experimenters enter the high-contamination zone 4 through the entrance door 51, the inner opening door 33 between the first changing room 31 and the clean zone 2, the first changing room 31, the inner opening door 33 between the first changing room 31 and the high-contamination zone 4, and then exit through the inner opening door 33 between the second changing room 32 and the high-contamination zone 4, the second changing room 32, the inner opening door 33 between the second changing room 32 and the clean zone 2, and the entrance door 51.

[0073] The first changing room 31 is located in the entrance passage, where experimental personnel can change into uncontaminated protective clothing; the second changing room 32 is located in the exit passage, where experimental personnel can remove contaminated protective clothing.

[0074] Optionally, the opening and closing methods of the inner opening and closing door 33 include any one or more combinations of zippers, magnetic adsorption, adhesive, hooks, and buckles. These opening and closing methods are simple and convenient, helping laboratory personnel to quickly open and close the inner opening and closing door 33, thereby reducing the communication time between the buffer unit 3 and the clean area 2, and the communication time between the buffer unit 3 and the high-contamination area 4.

[0075] Reference Figure 2 As shown, a lighting strip 74 is installed within the functional space 19, and the lighting strip 74 is fixed to the inflatable membrane structure 1 by Velcro and / or straps. Figure 2 In the illustrated embodiment, the lighting strip 74 is constructed as an arched strip, and the arched strip conforms to the inner surface of the inflatable membrane structure 1, thereby increasing the aesthetics of the lighting strip 74. In some embodiments not shown, the lighting strip 74 may also be constructed in other shapes, such as a straight strip, and extend along the length of the inflatable membrane structure virus detection laboratory to increase the length of the lighting strip 74 and expand the illumination range.

[0076] In some embodiments, the inflatable membrane structure 1 includes an inflatable membrane dome structure and an inflatable membrane isolation structure. The functional space 19 is defined by the inflatable membrane dome structure after inflation, and the buffer unit 3 is defined by the inflatable membrane isolation structure. The inflatable membrane isolation structure and the air membrane space 17 within the inflatable membrane dome structure can be connected or independent of each other.

[0077] exist Figure 1 , Figure 4 In the illustrated embodiment, the inflatable membrane dome structure includes a plurality of closely arranged arched inflatable rings 14, each inflatable ring 14 having an internal positive pressure air film space 17. In other words, the air film space 17 inside the inflatable ring 14 is a positive pressure environment, which ensures that the inflatable ring 14 has high rigidity and can play a supporting role to support the outside of the functional space 19, thereby maintaining the spatial shape of the functional space 19.

[0078] Reference Figure 4 As shown, the inflatable ring 14 includes an inner membrane 11 and an outer membrane 12, with an air film space 17 formed between the inner membrane 11 and the outer membrane 12. Preferably, the air film space 17 within each inflatable ring 14 is independent of each other, so that if one inflatable ring 14 is damaged, the other inflatable rings 14 can still be used without immediately replacing the entire inflatable membrane structure 1, and the damaged inflatable ring 14 can be repaired for continued use. Of course, the air film spaces 17 of multiple adjacent inflatable rings 14 can also be connected.

[0079] Furthermore, the inner side of the inflation ring 14 is covered with a single-layer membrane 13, which covers the inflation ring 14 from the inside. The inner surface of the single-layer membrane 13 is flat and there are no gaps between two adjacent inflation rings 14. As a result, the top of the functional space 19 is flat, avoiding the gaps between two adjacent inflation rings 14 from being exposed and causing an unsightly appearance. At the same time, the single-layer membrane 13 can make the inflation membrane dome structure have better sealing performance.

[0080] exist Figure 5 In the embodiment shown in (a), the inflatable membrane dome structure includes an outer support frame 15 and an inner single-layer membrane 13, forming a positive-pressure air-supported space 17 between the single-layer membrane 13 and the support frame 15. The support frame 15 can be multiple segments, with the single-layer membrane 13 attached to the edges of each segment and separated in the middle. Gas fills the space between the single-layer membrane 13 and each segment of the support frame, giving the inflatable membrane dome structure heat insulation and other properties. Simultaneously, multiple air-supported spaces 17 are formed between the single-layer membrane 13 and each segment of the support frame, ensuring that if one air-supported space 17 is damaged, the other air-supported spaces 17 can still be used normally.

[0081] exist Figure 5 In the embodiment shown in (b), the inflatable membrane dome structure includes: a support frame 15 located on the outer side and a double membrane located on the inner side. The double membrane is a double membrane with a positive pressure air membrane space 17 inside. The support frame 15 is restricted to the outer side of the double membrane and plays a limiting role in the double membrane.

[0082] The double-layer membrane includes an inner membrane 11 and an outer membrane 12, with the outer membrane 12 located outside the inner membrane 11. An air-supported membrane space 17 is formed between the inner membrane 11 and the outer membrane 12. The support frame 15 can be a multi-segment support frame, and the outer membrane 12 of the double-layer membrane is adapted to fit into each segment of the support frame. The double-layer membrane enables the inflatable membrane dome structure to have heat insulation and thermal insulation properties. Furthermore, the air-supported membrane space 17 can be multiple separate spaces, so that if one air-supported membrane space 17 is damaged, the other air-supported membrane spaces 17 can still be used normally.

[0083] The support frame 15 can be a steel frame, a plastic frame, or a composite material frame, or other frame structures that can provide support.

[0084] exist Figures 6-7In the illustrated embodiment, the inflatable membrane dome structure includes a supporting air column frame 16, which is constructed from multiple supporting air columns 161, each having an internal positive pressure air film space 17. The outer side of the supporting air column frame 16 is covered with a single-layer membrane 13 or a double-layer membrane with the positive pressure air film space 17. The supporting air column frame 16 serves to support the single-layer or double-layer membrane, while the outer side covering of the supporting air column frame 16 with a single-layer or double-layer membrane provides the inflatable membrane dome structure with heat insulation and other properties, and also ensures good sealing performance. In some embodiments, there are multiple supporting air columns 161; if one supporting air column 161 is damaged, the other supporting air columns 161 can still be used normally.

[0085] The inner membrane 11, outer membrane 12, single-layer membrane 13, and supporting air column 161 can be made of the same membrane material.

[0086] Reference Figure 1 , Figures 3-5 As shown, the inflatable membrane structure 1 has an air film space 17 and a membrane structure filling port and a membrane structure air outlet 18 communicating with the air film space 17. A blower is connected to the membrane structure filling port and blows air into the air film space 17. The air intake at the membrane structure filling port is greater than the air outlet at the membrane structure air outlet 18, so that the air film space 17 is a positive pressure air film space. The blower can be installed... Figure 2 The blower frame 56 shown can be fixedly connected to the inlet equipment frame 54 so that the blower frame 56 becomes part of the inlet equipment integration module 5.

[0087] The membrane material of the inflatable membrane structure 1 mainly includes fiberglass cloth, plastic film, and metal woven fabric, with fiberglass cloth being the preferred choice. Its surface can be coated with polytetrafluoroethylene (PTFE) or similar coatings to increase durability and fire resistance. Furthermore, it should be noted that after the inflatable membrane structure 1 is inflated, architectural coatings can be sprayed inside to enhance stability, physical protective properties, and improve isolation strength. For example, polyurethane waterproof coating can be sprayed inside the inflatable membrane structure 1 to enhance waterproofing.

[0088] The inflatable membrane structure 1 also possesses good toughness to prevent easy damage during installation or use. Furthermore, the inflatable membrane structure 1 can be transparent or a dark color that provides coverage, to meet different needs. Additionally, the thickness of the inflatable membrane structure 1 can be flexibly selected based on the length of the epidemic incubation period and quarantine period, or the complexity of the terrain.

[0089] In some embodiments not shown, the inflatable membrane structure 1 includes an inner membrane and an outer membrane, with an air film space formed between the inner and outer membranes. The seams of the materials of the inner and outer membranes can be formed by welding, bonding, or stitching. In some optional embodiments, the air film space can be a single, sealed cavity; in other optional embodiments, the air film space can be divided into multiple continuous sealed cavities. If one cavity is damaged, the other cavities can still be used without immediately replacing the entire inflatable membrane structure 1, and the damaged cavity can be repaired for continued use. Each sealed cavity has an inflation port on its corresponding outer membrane for pre-inflation. In short, double-layering the inflatable membrane structure 1 enhances airtightness and improves durability.

[0090] like Figure 1 As shown, the air ring 14 is provided with a membrane structure air outlet 18, and each air ring 14 has a membrane structure air outlet 18, or multiple air rings 14 share the same membrane structure air outlet 18.

[0091] According to some embodiments of this application, the high-pollution zone 4 is equipped with a humidifier to ensure that the humidity in the high-pollution zone 4 meets the humidity requirements, that is, to ensure that the humidity in the high-pollution zone 4 is within the range required by the technical specifications.

[0092] According to some embodiments of this application, one or more skylights are provided at the top of the high-pollution zone 4 for lighting or ventilation. Each skylight is equipped with an inward-facing one-way filter, allowing only outside air to enter the high-pollution zone 4 through the filter, while preventing air from escaping from the high-pollution zone 4, thus effectively preventing the leakage of viruses from the high-pollution zone 4. In practical scenarios, the skylights can meet the lighting and ventilation needs of the high-pollution zone 4.

[0093] Reference Figure 3 As shown, the high-pollution zone 4 has a first transfer port 41 and a second transfer port 42, and transfer units are suitable for being installed at the first transfer port 41 and the second transfer port 42.

[0094] Optionally, the transfer unit is a material transfer box and / or a personnel passage box 45. There can be one or more first transfer ports 41 and second transfer ports 42. Material transfer boxes or personnel passage boxes 45 can be set at the first transfer port 41 and the second transfer port 42, or both material transfer boxes and personnel passage boxes 45 can be set at the same time.

[0095] exist Figure 3 In the embodiment shown, the transfer unit is a material transfer box (e.g., intermediate material transfer box 43, feed transfer box 44), through which samples or reagents can be transferred to the high-contamination area 4.

[0096] In some embodiments not shown, the transfer unit is a personnel access box 45 for experimental personnel to enter and exit.

[0097] exist Figure 11 In the embodiment shown, the transfer unit is a material transfer box and a personnel passage box 45. Samples or reagents can be transferred to the high-contamination area 4 through the material transfer box, or the experimental personnel can carry the samples or reagents through the personnel passage box 45 to transfer them to the high-contamination area 4.

[0098] In some embodiments, both the transfer unit and the waste transfer box 61 include an inner door facing the high-contamination area 4 and an outer door facing the outside. Both the transfer unit and the waste transfer box 61 employ intelligent interaction technology to create an intelligent interlocking structure between the inner and outer doors, ensuring that they cannot be opened simultaneously. This guarantees that the transfer unit and waste transfer box 61 function as isolation points, preventing the inner side of the inner door from connecting to the outer side of the outer door, thus ensuring the safety of the inflatable membrane structure virus detection laboratory. In some optional embodiments, the intelligent interaction technology can be optical interaction technology, making the inner and outer doors optically interactive doors, using a mobile phone flash or flash ring to issue open or close commands to the inner and outer doors. In other optional embodiments, the inner and outer doors can also be voice-interactive doors, using voice commands to open or close them. This ensures that even when laboratory personnel are wearing protective clothing, contactless control of the transfer unit and waste transfer box 61 can be achieved without facial scanning.

[0099] In some embodiments, the inflatable membrane structure 1 can be folded and stored by removing the gas. The inflatable membrane structure 1 has a high volume compression ratio, allowing for the storage of a large number of folded inflatable membrane structures 1 in a limited space, and enabling the rapid construction of laboratories. During an outbreak, the inflatable membrane structure virus testing laboratory described in this application can serve as a temporary building near the outbreak site for emergency use. After the peak of the outbreak has passed, the inflatable membrane structure virus testing laboratory described in this application can be degassed, the inflatable membrane structure 1 disinfected and recycled, facilitating its subsequent transfer to a new location and reassembly.

[0100] The outer surface of the inflatable membrane structure 1 can be upgraded or transformed into a permanent building by spraying building industrial materials, pouring concrete, and covering with vegetation, using any one or more combinations of these methods.

[0109] Optionally, the drying chamber 101 is located near the first sample inlet, so that samples entering from the first sample inlet can be placed in the drying chamber 101 for inactivation, reducing the time that uninactivated samples stay in the first inflatable membrane structure virus detection laboratory 10.

The sterilized waste is then delivered to an external waste receiving device via a corresponding waste transfer box 61, ensuring that all waste discharged from the biosafety laboratory is sterilized waste and preventing secondary pollution to the environment. The waste flow path at the waste transfer box 61 is as follows: Figure 10 The E1 and E2 streamlines are shown in the figure.

[0115] According to the second aspect of the present application, the biosafety laboratory separates the sample receiving and preparation area from the amplification area through a transfer unit, which is beneficial to improving the safety of the biosafety laboratory. In the event of leakage of diffused nucleic acid in the amplification area, the leaked nucleic acid can be prevented from entering the sample receiving and preparation area.
