Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, and in particular to an infection control isolation room. Background Technology

[0002] The core function of isolation rooms in medical institutions is to block the transmission path of pathogens between the source of infection and susceptible populations through the dual effects of physical barriers and airflow control. Current mainstream solutions employ fixed isolation wards (such as negative pressure wards) or temporary partitions (such as PVC curtains), the technical implementation of which relies on building modifications or simple hanging structures. When a sudden outbreak of respiratory infectious diseases occurs, rapid response to the emergency is required, but traditional technologies have structural defects. ① Spatial adaptability defects: Fixed isolation rooms require customized construction, which cannot match the diverse sizes of existing hospital wards, resulting in insufficient deployment rates in emergency scenarios. ② Continuous protection defects: Disinfection relies on manual spraying or ultraviolet disinfection, lacking automatic disinfection functions, failing to provide effective isolation, and potentially causing cross-infection. ③ Emergency response defects: Laminar flow hoods and negative pressure wards are costly and time-consuming to construct, unable to quickly respond to large-scale emergency needs. Chinese invention patent CN119523746A discloses a hospital infection control isolation protection device and method. It features an infection control isolation protection shield above the isolation bed, effectively isolating infected patients within the shield and completely enclosing them on the bed. While this effectively prevents splashes of bodily fluids or blood, significantly reducing cross-infection, its complex structure and high cost make it difficult to mass-produce, and the limited isolation space can cause patient discomfort. Chinese invention patent CN106955006A discloses a structurally improved medical clean laminar flow hood, where the curtain can be retracted and expanded via a slider. However, its structure is simple, lacks antibacterial properties, and cannot adapt to different bed sizes or rapid emergency response needs. Summary of the Invention

[0018] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0019] like Figures 1 to 11 As shown, an embodiment of the present invention proposes an infection control isolation room, comprising: Top support, the upper surface of the top support is sealed and abuts against the interior ceiling of the house; Multiple support columns, which are detachably connected to the top bracket; The base bracket is connected to any support column; Antibacterial isolation curtain 2 is detachably connected to the outer side of the top support. The antibacterial isolation curtain 2 is located on the outside of multiple support columns, and the bottom of the antibacterial isolation curtain 2 abuts against the floor of the building to form a columnar isolation space in which the hospital bed is located. The color of the antibacterial isolation curtain 2 changes with its antibacterial ability. An entrance curtain 21 and an exit curtain 22 that can close automatically are mounted on an antibacterial isolation curtain 2. Pipe opening 25 is set on the antibacterial isolation curtain 2, and the wiring or pipes of medical equipment pass through pipe opening 25; An air supply outlet 23 and an air return outlet 24 are installed on the antibacterial isolation curtain 2, and an antibacterial air filter membrane 231 is installed at both the air supply outlet 23 and the air return outlet 24. An exit disinfection device is installed at the exit curtain 22. When the exit curtain 22 is opened, the exit disinfection device sprays disinfectant onto the exit curtain 22.

[0020] In this embodiment, a load-bearing frame is formed by a top bracket, multiple support columns, and a base bracket. The antibacterial isolation curtain 2 is connected to the top bracket, so that the antibacterial isolation curtain 2 is located on the outside of multiple support columns, and the bottom of the antibacterial isolation curtain 2 abuts against the floor of the building to form a columnar isolation space. The hospital bed is located in the isolation space to form an isolation room. The assembly operation is simple and convenient, and the isolation room can be quickly assembled to meet the isolation needs of the hospital bed. The antibacterial isolation curtain 2 can actively inhibit bacteria and block the spread of aerosols, resulting in a good isolation effect. Since the color of the antibacterial isolation curtain 2 changes with its antibacterial ability, the antibacterial effect and service life can be monitored in real time by using the color change, which makes it easy to replace the antibacterial isolation curtain 2 in a timely manner and ensure its antibacterial effect. By setting an entrance curtain 21 and an exit curtain 22 on the antibacterial isolation curtain 2, the entry and exit of personnel can be separated and orderly, avoiding the chaos caused by personnel sharing a single passage and thus preventing aerosol leakage. When personnel enter through the entrance curtain 21, the airflow allows outside air to enter the isolation space, preventing aerosol leakage from the isolation space. When the exit curtain 22 is opened, disinfectant is sprayed onto the opening of the exit curtain 22 by the exit disinfection device, disinfecting medical personnel and the space around the opening of the exit curtain 22, thus preventing aerosol leakage when personnel leave.

[0021] In this embodiment, by setting a pipe opening 25 on the antibacterial isolation curtain 2, it is convenient for the lines or pipes of medical equipment to enter the isolation space, while ensuring the isolation requirements are met; in specific applications, the pipe opening 25 is close to the head of the bed.

[0022] In this embodiment, by setting up an air supply outlet 23 and a return air outlet 24, the air supply outlet 23 is connected to the air supply duct of the air conditioning unit or fresh air handling unit in the ward, and the return air outlet 24 is connected to the return air duct of the ward. The return air duct of the ward leads to the air conditioning unit (for return air reprocessing) or the exhaust system or ultraviolet disinfection equipment. With the columnar isolation space, an orderly airflow circulation is formed to reduce cross-contamination. In specific applications, the air supply outlet 23 is set at the upper part of the antibacterial isolation curtain 2, and the return air outlet 24 is located at the lower part of the antibacterial isolation curtain 2. The return air outlet 24 is close to the head of the bed to form an upward supply and downward exhaust circulation mode. Through this upward supply and downward exhaust mode, the clean air supplied first flows through the activity area of ​​medical staff and patients, and then carries indoor pollutants out from the return air outlet 24, forming an orderly airflow circulation to reduce cross-contamination. At the same time, the positions of the air supply outlet 23 and the return air outlet 24 are avoided directly above or at the head of the bed to prevent the airflow from blowing directly on the patient and causing discomfort. The antibacterial isolation curtain 2 forms a columnar isolation space, the cross-section of which can be circular or elliptical, so that the isolation space has no right angles or protruding dead corners. The airflow can diffuse along a continuous and smooth path under the guidance of the curved surface, reducing eddies or airflow turbulence caused by structural abrupt changes, which is conducive to unidirectional airflow and ensures the ventilation effect of the air supply port 23 and the return air port 24. The air supply outlet 23 is connected to the air supply duct of the ward's air conditioning unit or fresh air handling unit via a guide duct, and the return air outlet 24 is connected to the ward's return air duct; specifically, such as Figures 9 to 11 As shown, the flow guiding duct includes: a first connecting ring 51 disposed at the air supply outlet 23 or the air return outlet 24, with multiple insertion posts 52 evenly arranged on the first connecting ring 51; a flow guiding channel formed by a sealing membrane, with a second connecting ring 53 and a third connecting ring 55 respectively disposed on both sides of the flow guiding channel; multiple insertion holes 54 are provided through the surface of the second connecting ring 53, and the multiple insertion holes 54 are inserted and engaged with the multiple insertion posts 52; multiple buckles 56 are provided on the surface of the third connecting ring 55, and the multiple buckles 56 are adapted to the grooves at the ends of the air supply duct or the air return duct; the first connection is achieved by inserting the multiple insertion posts 52 into the multiple insertion holes 54. The second connecting ring 53 is connected to the first connecting ring 51, and the first connecting ring 51 is in close contact with the second connecting ring 53. Multiple clips 56 are connected to the slots at the ends of the air supply or return duct, thus connecting the third connecting ring 55 to the air supply or return duct. This connects the air supply outlet 23 to the air supply duct of the ward's air conditioning unit or fresh air handling unit, and the return air outlet 24 to the ward's return air duct. In practical applications, two air supply outlets 23 are provided, including a main air supply outlet and a secondary air supply outlet. Depending on the actual distribution of the ward, the main air supply outlet is located on the side of the bed, and the secondary air supply outlet is located at the foot of the bed. The air supply outlet 23 is connected to the air supply duct of the ward's air conditioning unit or fresh air handling unit. By installing antibacterial air filter membranes 231 at both the air supply outlet 23 and the air return outlet 24, the antibacterial air filter membranes 231 are made of meltblown polypropylene masterbatch through meltblown spinning to form nonwoven fabric. The three-dimensional structure of the nonwoven fabric fibers forms the first barrier, which can effectively capture particulate matter such as dust and droplets in the air and reduce pollutants transmitted through the air supply and return systems. By introducing antibacterial components into the nonwoven fabric, it can inhibit or kill microorganisms while intercepting them, reducing the risk of microbial growth and secondary pollution on the surface of the filter membrane. The antibacterial air filter membrane 231 can be produced by impregnation process, or by directly using antibacterial polymer masterbatch for melt production. Alternatively, the antibacterial agent can be melt-blended and spun together with the polypropylene masterbatch during melting. Furthermore, the antibacterial finishing liquid can be coated onto the surface of the plasma-pretreated polypropylene nonwoven fabric through post-treatment. By controlling the loading of the antibacterial agent to be no less than 5%, the longest antibacterial time is no less than 30 days.

[0023] like Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the top support includes: The first arc-shaped rod 11 and the second arc-shaped rod 12 are symmetrically distributed; The first tee is provided in two parts. The two first horizontal insertion pipes 181 of the first tee are respectively inserted into the ends of the first arc rod 11 and the second arc rod 12; the first vertical insertion pipe 182 of the first tee is inserted into the support column.

[0024] In this embodiment, a top bracket is formed by inserting the ends of the first arc-shaped rod 11 and the second arc-shaped rod 12 into the two first horizontal connectors 181 of the two first tees, respectively; the first arc-shaped rod 11, the second arc-shaped rod 12 and the two first tees facilitate the assembly of the top bracket.

[0025] like Figure 5 As shown, in an optional embodiment of the present invention, the first arc-shaped rod 11 and the second arc-shaped rod 12 both include multiple folding rods 111, adjacent folding rods 111 are rotatably connected by a damping shaft 112, and a first magnetic strip 17 is embedded on the outer side of the folding rod 111.

[0026] In this embodiment, the damping shaft 112 enables the rotational connection of adjacent folding rods 111, allowing for angle adjustment and fixation between adjacent folding rods 111. By forming a first arc-shaped rod 11 and a second arc-shaped rod 12 from multiple folding rods 111, the first arc-shaped rod 11 and the second arc-shaped rod 12 can be folded, reducing the space occupied by the first arc-shaped rod 11 and the second arc-shaped rod 12 and facilitating storage.

[0027] like Figure 1 and Figure 2As shown, in an optional embodiment of the present invention, the plurality of support columns include: The first support column 13 and the second support column 14 are respectively connected to the first vertical insertion pipe 182 of the two first tee joints.

[0028] In this embodiment, the top support can be supported by the first support column 13 and the second support column 14 and the first vertical insertion pipe 182 of the two first tee joints, so that the top support can fully contact the ceiling of the house.

[0029] like Figure 8 As shown, in an optional embodiment of the present invention, both the first support column 13 and the second support column 14 include: Multiple splicing pipes 131, each having a threaded connection portion 132 formed at its first end, and each having a threaded connection cavity 133 formed at its second end, with the threaded connection cavity 133 being threadedly connected to the threaded connection portion 132.

[0030] In this embodiment, the two splicing pipes 131 are connected by the threaded connection part 132 and the threaded connection cavity 133. The first support column 13 and the second support column 14 are formed by multiple splicing pipes 131, which can realize the height adjustment of the first support column 13 and the second support column 14 to ensure that the top support is fully in contact with the ceiling of the house.

[0031] like Figure 1 and Figure 3 As shown, in an optional embodiment of the present invention, the base support includes: The second three-way connector, the second vertical insertion pipe 191 of the second three-way connector is inserted and matched with the first support column 13; The first support rod 15 and the second support rod 16 are respectively connected to the two second horizontal connectors 192 of the second tee.

[0032] In this embodiment, the first support rod 15 and the second support rod 16 are respectively inserted into the two second horizontal insertion pipes 192 of the second tee, and the bottom of the first support column 13 is inserted into the second vertical insertion pipe 191 of the second tee, so as to realize the detachable connection between the base bracket and the support column. The first support rod 15 and the second support rod 16 provide support, which ensures the overall stability while simplifying the structure of the base bracket and making it easy to disassemble and assemble. In practical applications, the first support column 13 is far from the bed, and the second support column 14 is close to the head of the bed, so that the first support rod 15 and the second support rod 16 are far away from the bed, thereby avoiding the first support rod 15 and the second support rod 16 from affecting the treatment operations of medical staff and ensuring the safety of medical staff when walking.

[0033] like Figure 6 As shown, in an optional embodiment of the present invention, the antibacterial isolation curtain 2 has a rectangular structure. A second magnetic strip 26 is provided on the upper side of the antibacterial isolation curtain 2. The second magnetic strip 26 and the first magnetic strip 17 embedded on the outer side of the top support have opposite magnetic properties to connect the antibacterial isolation curtain 2 and the top support. A third magnetic strip 251 and a fourth magnetic strip 252 are respectively provided on both sides of the antibacterial isolation curtain 2. The third magnetic strip 251 and the fourth magnetic strip 252 have opposite magnetic properties to form a columnar isolation space in the antibacterial isolation curtain 2, and a pipe opening 25 is formed between the third magnetic strip 251 and the fourth magnetic strip 252.

[0034] In this embodiment, the magnetic attraction between the second magnetic strip 26 and the first magnetic strip 17 enables the detachable connection between the antibacterial isolation curtain 2 and the top support; the magnetic attraction between the third magnetic strip 251 and the fourth magnetic strip 252 enables the two sides of the antibacterial isolation curtain 2 to be joined, thereby forming a columnar isolation space; wherein, the second magnetic strip 26, the third magnetic strip 251 and the fourth magnetic strip 252 can be fixedly connected to the antibacterial isolation curtain 2 by high-frequency welding.

[0035] In this embodiment, both the third magnetic strip 251 and the fourth magnetic strip 252 are flexible magnetic strips, and a pipe opening 25 is formed between the third magnetic strip 251 and the fourth magnetic strip 252. When the wiring or pipe of the medical device passes through the pipe opening 25, the third magnetic strip 251 and the fourth magnetic strip 252 can make full contact with the wiring or pipe of the medical device. At the same time, the gap between the pipe opening 25 and the wiring or pipe of the medical device is filled with sealing cotton to ensure the sealing performance of the pipe opening 25.

[0036] In this embodiment, two entrance curtains 21 are provided, one near each side of the antibacterial isolation curtain 2. When the antibacterial isolation curtain 2 is arranged, the pipe opening 25 is placed near the head of the bed, so the two entrance curtains 21 are located on both sides of the head of the bed, facilitating medical staff to enter and treat the patient. With two entrance curtains 21 located on each side of the head of the bed, one entrance curtain 21 can be used as an entry channel for medical staff, while the other entrance curtain 21 is used as a dedicated channel for material transfer (such as medicines, equipment, meals, etc.). This reduces cross-contact between personnel and materials in different operational processes, lowering the probability of pathogens spreading through operational steps. The exit curtain 22 is located in the middle of the antibacterial isolation curtain 2. After the antibacterial isolation curtain 2 is arranged, the exit curtain 22 is far away from the bed. With the airflow of the air supply port 23 and the return air port 24, it can prevent aerosols from leaking from the exit curtain 22.

[0037] In this embodiment, the return air vent 24 is located near the side of the antibacterial isolation curtain 2. After the antibacterial isolation curtain 2 is arranged, the return air vent 24 is located below the head of the hospital bed.

[0038] In this embodiment, a rubber strip is provided at the bottom of the antibacterial isolation curtain 2. After the antibacterial isolation curtain 2 is arranged, the rubber strip contacts the floor of the house to achieve a seal between the antibacterial isolation curtain 2 and the floor of the house.

[0039] like Figure 4 As shown, in an optional embodiment of the present invention, the infection control isolation room further includes: The connecting sealing strip 4 has a receiving cavity 41 inside to accommodate the first arc-shaped rod 11 and the upper part of the antibacterial isolation curtain 2; the bottom of the connecting sealing strip 4 has an insertion port 42, which communicates with the receiving cavity 41.

[0040] In this embodiment, the top bracket is assembled using the first arc-shaped rod 11, the second arc-shaped rod 12, and the first tee. A first magnetic strip 17 is embedded on the outer side of both the first arc-shaped rod 11 and the second arc-shaped rod 12, thus embedding the first magnetic strip 17 into the outer side of the top bracket. The magnetic attraction between the first magnetic strip 17 and the second magnetic strip 26 enables a detachable connection between the antibacterial isolation curtain 2 and the top bracket. A connecting sealing strip 4 is pressed onto the outer side of the top bracket through the insertion port 42, ensuring that the upper parts of the first arc-shaped rod 11, the second arc-shaped rod 12, and the antibacterial isolation curtain 2 are all located inside the receiving cavity 41. The connecting sealing strip 4 fully contacts the upper parts of the first arc-shaped rod 11, the second arc-shaped rod 12, and the antibacterial isolation curtain 2, thereby achieving a tight seal between the top bracket and the antibacterial isolation curtain 2. When the top bracket contacts the interior ceiling, the connecting sealing strip 4 fully contacts the interior ceiling to ensure a tight seal between the top bracket and the interior ceiling, preventing aerosol leakage.

[0041] like Figure 7 As shown, in an optional embodiment of the present invention, both the entrance curtain 21 and the exit curtain 22 include: The first curtain 271 and the second curtain 272 are both located within the gap of the antibacterial isolation curtain 2. The upper part of the first curtain 271 and the second curtain 272, as well as the side parts of the first curtain 271 and the second curtain 272 that are far apart from each other, are connected to the antibacterial isolation curtain 2. The side parts of the first curtain 271 and the second curtain 272 that are close to each other are respectively evenly provided with a first magnetic block 281 and a second magnetic block 282. The first magnetic block 281 and the second magnetic block 282 have different magnetic properties.

[0042] In this embodiment, the magnetic attraction between the first magnetic block 281 and the second magnetic block 282 enables the automatic closing of the first curtain 271 and the second curtain 272. With this structure, medical staff can enter and exit by turning around with their backs to the door, avoiding the potential infection risk caused by direct hand contact with the curtain.

[0043] In this embodiment, both the first curtain 271 and the second curtain 272 are made of antibacterial transparent PVC film. During the production of the antibacterial transparent PVC film, polyvinyl chloride resin is mixed with plasticizer, heat stabilizer, lubricant and other substances in proportion, and stirred at high speed until a uniform paste mixture is formed. Then, it is transferred to a low-speed mixer for cooling. Subsequently, the cooled mixture is added to an extruder, melted and plasticized, and extruded into a sheet film through a T-shaped die head. The film is then cast, cooled and shaped. After the antibacterial transparent PVC film is cut, the first magnetic block 281 and the second magnetic block 282 are fixed by hot melt adhesive bonding or high-frequency heat sealing.

[0044] In this embodiment, luminous strips are affixed to both the first curtain 271 and the second curtain 272 of the entrance curtain 21. These luminous strips can indicate the location of the entrance curtain 21 at night, facilitating ward rounds and treatments by medical staff. The main component of the luminous strip is a long-afterglow luminescent material aluminate system, which does not contain heavy metals and is a non-toxic and environmentally friendly material. Its working principle is that when the long-afterglow luminescent material is irradiated by natural light, ultraviolet light, or visible light, the activator (such as Eu²⁺) in the material absorbs photon energy, and electrons transition from the ground state to a higher-energy excited state. The doped co-activator (such as Dy³⁺, Nd³⁺) forms a "trap" in the crystal, capturing and storing the excited-state electrons to prevent them from releasing energy immediately. When the external light source disappears, the electrons in the "trap" gradually break free from their bondage due to thermal disturbances and other reasons, returning to the ground state and releasing the stored energy in the form of visible light, thereby achieving continuous luminescence.

[0045] like Figure 1 As shown, in an optional embodiment of the present invention, the outlet disinfection device includes: A liquid storage tank 31 is provided with a control module 32. Infrared sensor 34 is detachably connected to antibacterial isolation curtain 2. The infrared sensor 34 is located above the exit curtain 22 to detect the opening status of the exit curtain 22. The infrared sensor 34 is electrically connected to the control module 32. The liquid supply pump is connected to the liquid storage tank 31. The liquid supply pump has a suction pipe connected to its inlet end. The suction pipe extends into the liquid storage tank 31. The liquid supply pump is electrically connected to the control module 32. The micro-mist nozzle 33 is detachably connected to the antibacterial isolation curtain 2. The liquid outlet of the micro-mist nozzle 33 corresponds to the opening of the outlet curtain 22. The micro-mist nozzle 33 is connected to the liquid outlet of the liquid supply pump through a liquid guide pipe.

[0046] In this embodiment, when medical staff approach and open the exit curtain 22, the infrared sensor 34 is triggered, and the control module 32 controls the liquid supply pump to work, delivering the disinfectant in the storage tank 31 to the micro-mist nozzle 33. The micro-mist nozzle 33 sprays the disinfectant onto the medical staff and the space at the opening of the exit curtain 22 to achieve disinfection and prevent aerosols in the isolation space from leaking out through the exit curtain 22 when medical staff pass through it, thus ensuring the isolation effect. In practical applications, both the infrared sensor 34 and the micro-mist nozzle 33 can be detachably connected to the inside of the antibacterial isolation curtain 2 by means of adhesive or clips. Multiple micro-mist nozzles 33 can be provided and evenly distributed vertically on both sides of the bottom of the outlet curtain 22 to ensure that the disinfectant can be fully and evenly sprayed to the opening of the outlet curtain 22. Specifically, the highest micro-mist nozzle 33 can be 1.2m above the ground, and the angle between the liquid outlet direction of the micro-mist nozzle 33 and the horizontal direction is 60° to ensure that the disinfectant can be fully sprayed to the main contaminated areas of the medical staff's torso and the opening of the outlet curtain 22, while avoiding the disinfectant from being sprayed onto the face of the medical staff. Specifically, the disinfectant in the storage tank 31 can be hydrogen peroxide, which uses 0.5-1% hydrogen peroxide to generate reactive oxygen free radicals (·OH) to destroy the viral envelope / protein capsid to achieve disinfection.

[0047] In an optional embodiment of the present invention, the antibacterial isolation curtain 2 includes: Outer protective film; The inner antibacterial nonwoven fabric is connected to the inner surface of the outer protective film and is located within the isolation space.

[0048] In this embodiment, the outer protective film and the inner antibacterial non-woven fabric ensure the overall strength of the antibacterial isolation curtain 2 while giving it a good antibacterial effect and preventing the leakage of aerosols in the isolation space; wherein, the outer protective film can be a PEVA (polyethylene-vinyl acetate) film.

[0049] In an optional embodiment of the present invention, the inner antibacterial nonwoven fabric is composed of a zinc-based metal-organic framework and meltblown polypropylene nonwoven fabric; the zinc-based metal-organic framework is a metal-organic framework composed of zinc ions as metal nodes, which form coordination bonds with 2-aminoterephthalic acid and azobenzene-4,4-dicarboxylic acid blend ligands.

[0050] In this embodiment, the inner antibacterial nonwoven fabric is composed of a zinc-based metal-organic framework (MOF) and meltblown polypropylene nonwoven fabric; and the zinc-based MOF is based on zinc ions (ZnO2). 2+The metal-organic framework (MOF) consists of metal nodes that form coordination bonds with ligands of 2-aminoterephthalic acid (NH2-BDC) and azobenzene-4,4-dicarboxylic acid (AZO-BDC). The Zn-MOF in the inner antibacterial nonwoven fabric provides long-lasting antibacterial action and indicates the antibacterial effect and replacement cycle of the antibacterial isolation curtain 2 through color changes. Specifically, under ambient humidity, the coordination bonds of Zn-MOF slowly break, and the AZO-BDC ligands detach from the Zn... 2+ It then gradually changes from orange-red to bright yellow (the azo group in AZO-BDC is orange-red in the coordinated state, and returns to bright yellow after detaching from the coordination), while Zn 2+ It gradually releases its antibacterial properties; during use, the initial color of the inner antibacterial nonwoven fabric is dark orange-red. As the usage time increases, the color of the inner antibacterial nonwoven fabric gradually changes (dark orange-red → orange-red → light orange → orange-yellow → bright yellow). The color change corresponds to the antibacterial component Zn. 2+ As the release level increases, when the color of the inner antibacterial nonwoven fabric turns completely bright yellow, it indicates that the antibacterial components have been fully released, suggesting that the antibacterial isolation curtain 2 should be replaced.

[0051] The processing technology of antibacterial isolation curtain 2 is as follows: Meltblown polypropylene nonwoven fabric is produced by meltblown spinning of meltblown polypropylene masterbatch. Zinc nitrate and two ligands were dissolved in N,N-dimethylformamide (DMF) in a certain proportion by a solvothermal method. After reaction at 120°C, Zn-MOF (zinc-based metal-organic framework) particles were obtained by centrifugation. Meltblown polypropylene nonwoven fabric is immersed in an ethanol-water solution containing Zn-MOF particles. After ultrasonic-assisted adsorption, it is vacuum dried at 60°C to make the Zn-MOF particles uniformly adhere to the fiber surface and gaps of the meltblown polypropylene nonwoven fabric, thus obtaining an inner antibacterial nonwoven fabric. The antibacterial isolation curtain 2 is obtained by combining PEVA film and antibacterial non-woven fabric through a four-sided hot-pressing composite method.

[0052] The assembly process for infection control isolation wards is as follows: The adjacent folding rods 111 are unfolded by the damping shaft 112 to form a first arc rod 11 and a second arc rod 12; the ends of the first arc rod 11 and the second arc rod 12 are respectively inserted into the two first horizontal insertion pipes 181 of the two first tees to form a top support; wherein, the top support can be an elliptical structure. The upper part of the antibacterial isolation curtain 2 is connected to the outside of the top support by the magnetic attraction between the first magnetic strip 17 and the second magnetic strip 26. The antibacterial isolation curtain 2 forms a columnar isolation space with an elliptical cross section by the magnetic attraction between the third magnetic strip 251 and the fourth magnetic strip 252. The connecting sealing strip 4 is pressed onto the outside of the top bracket through the insertion port 42, so that the upper part of the first arc rod 11, the second arc rod 12 and the antibacterial isolation curtain 2 are all located inside the receiving cavity 41. The connecting sealing strip 4 is in full contact with the upper part of the first arc rod 11, the second arc rod 12 and the antibacterial isolation curtain 2, thereby achieving a connection seal between the top bracket and the antibacterial isolation curtain 2 through the connecting sealing strip 4. The connection of two splicing pipes 131 is achieved through the threaded connection part 132 and the threaded connection cavity 133, and the first support column 13 and the second support column 14 are formed by multiple splicing pipes 131. Insert the first support column 13 and the second support column 14 into the first vertical insertion pipe 182 of the two first tees respectively. The first support column 13 and the second support column 14 support the top bracket, so that the top bracket contacts the ceiling of the house, thereby making the connecting sealing strip 4 fully contact the ceiling of the house. Insert the first support rod 15 and the second support rod 16 into the two second horizontal connectors 192 of the second tee respectively, and insert the bottom of the first support column 13 into the second vertical connector 191 of the second tee to achieve a detachable connection between the base bracket and the support column. The hospital bed is located in an isolation space, with the specific pipe opening 25 close to the head of the bed at a distance of 0.75m, and the two entrance curtains 21 located on both sides of the hospital bed at a distance of 0.9m.

[0053] The infection control isolation room provided in the above embodiments of the present invention can be quickly assembled into a frame through a top bracket, multiple support columns, and a base bracket. Combined with the antibacterial isolation curtain 2, it enables rapid assembly of the isolation room to meet the isolation needs of hospital beds. The antibacterial isolation curtain 2 can actively inhibit bacteria, block aerosol transmission, and monitor the antibacterial effect and usage cycle in real time using color changes. Both the entrance curtain 21 and the exit curtain 22 can close automatically, and an exit disinfection device is installed at the exit curtain 22 to avoid the risk of leakage and contamination. The antibacterial isolation curtain 2 is a disposable consumable, while the top bracket, multiple support columns, and base bracket are reusable. This combination method can reduce the cost of infection control isolation rooms, improve the hospital's emergency coverage capacity, and meet the requirements of the "Technical Standard for Isolation Unit Construction" and the "WS / T 311-2023 Hospital Isolation Technical Standard".

[0054] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
