Description

Technical Field

[0001] This utility model relates to the field of purification, and more specifically, to an air shower device. Background Technology

[0002] An air shower, as the name suggests, is a device that uses airflow to remove dust and bacteria. For hospitals and other medical institutions, reducing cross-infection, improving cleanliness, and reducing the use of disinfectants are top priorities. Therefore, air showers are widely used in hospitals and other medical institutions, especially in areas with extremely high environmental requirements such as operating rooms and ICUs.

[0003] To achieve the desired purification effect, existing medical air shower rooms employ multi-stage (usually three-stage) purification. Each stage of the multi-stage purification is independent of the others, and each is divided into its own independent space for purification. To facilitate entry from one purification space to the next, a partition curtain is typically used to separate the two independent purification spaces. The person being purified enters the next purification space by lifting the partition curtain. In each independent purification space, the air shower nozzles are located on the walls at both ends and on the ceiling.

[0004] While such medical air showers can achieve the purpose of purification, the airflow in the purification space is usually large in order to achieve the purification effect. Therefore, the partition curtains need to be of a certain thickness and weight. As a result, the partition curtains are generally quite heavy. Therefore, it is very inconvenient for those who need to pass through the air shower, especially for younger people (such as children) or older people (such as the elderly). Passing through the existing air shower is very painful for them. Utility Model Content

[0029] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0030] Example 1

[0031] Please refer to Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of an air shower device provided by this utility model. Figure 2 This is a schematic cross-sectional view of the air shower chamber in this embodiment. Figure 3 This is a schematic diagram of the cleanroom structure of this utility model.

[0032] An air shower device includes an air shower chamber 1 and a cleanroom 2. The air shower chamber 1 is located inside the cleanroom 2. The air shower chamber 1 includes a front wall 17, a left side wall 18, a right side wall 5, a rear wall 19, a floor 3, and a ceiling 4. An inlet 11 is provided on the front wall 17, and an outlet 10 is provided on the rear wall 19. The outlet 10 communicates with the cleanroom 2. A first partition 6, a second partition 7, and a third partition 8 are provided between the front wall 17 and the rear wall 19 inside the air shower chamber 1. The first partition 6, the second partition 7, and the third partition 8 are equidistant. The width of the first partition 6, the second partition 7, and the third partition 8 is smaller than the width of the front wall 17 or the rear wall 19. The first partition 6, the second partition 7, and the third partition 8 form a progressive purification channel 12 between the inlet 11 and the outlet 10 inside the air shower chamber 1. The progressive purification channel 12 consists of a first forward purification channel 13, a first reverse channel 14, a second forward channel 15, and a second reverse channel 16. The first forward purification channel 13 is connected to the inlet 11, and the second reverse channel 16 is connected to the outlet 10. The first forward purification channel 13 turns at the left wall 18 to enter the first reverse channel 14. The first reverse channel 14 turns at the right wall 5 to enter the second forward channel 15. The second forward channel 15 turns at the left wall 18 to enter the second reverse channel 16. Air shower nozzles (not shown in the figure) are installed on the front wall 17, left wall 18, right wall 5, rear wall 19, ceiling 4, first partition 6, second partition 7, and third partition 8 to blow away dust particles and other particles and produce clean airflow.

[0033] On the one hand, by setting up the first partition 6, the second partition 7, and the third partition 8, a first forward purification channel 13, a first reverse channel 14, a second forward channel 15, and a second reverse channel 16 are formed. This allows the person being purified to enter through the inlet 11 and then walk through the first forward purification channel 13. Upon reaching the left wall 18, they turn into the first reverse channel 14, and so on, being purified as they walk. The cleanliness level increases throughout the walking process, reaching its highest level at the outlet 10. The entire purification process is essentially a walking process, making it easy and convenient, especially suitable for children and the elderly. On the other hand, replacing the original partition curtain with the first partition 6, the second partition 7, and the third partition 8 increases the installation direction of the air shower nozzles (the partition curtain needs to be opened, and the curtain itself prevents the installation of air shower nozzles, thus eliminating the cleaning effect in that direction). This increases purification from the partition direction, effectively achieving full-body, leak-free purification and improving the overall purification effect.

[0034] In one or more specific embodiments of this utility model, the right end of the first partition 6 is connected to the right side wall 5, and the distance H1 between its left end and the left side wall 18 is 300mm to 600mm. The left side of the second partition 7 is connected to the left side wall 18, and the right end is connected to the right side wall 5, with a distance H2 of 300mm to 600mm. The right end of the third partition 8 is connected to the right side wall 5, and the distance H3 between its left end and the left side wall 18 is 300mm to 600mm. This 300mm to 600mm spatial distance setting avoids discomfort for the person being purified, while also preventing the space from being too large, which could affect the purification effect and increase permissible costs.

[0035] In one or more specific embodiments of this utility model, the widths of the first forward purification channel 13, the first reverse channel 14, the second forward channel 15, and the second reverse channel 16 are 300mm to 600mm. This 300mm to 600mm width setting avoids discomfort for the person being purified, while also preventing the space from being too large, which could affect the purification effect and increase permissible costs.

[0036] In one or more specific embodiments of this utility model, the width of the outlet 10 and the inlet 11 is 300mm to 600mm.

[0037] In one or more specific embodiments of this utility model, the first partition 6, the second partition 7, and the third partition 8 are all purification plates.

[0038] In one or more specific embodiments of this utility model, the air volume at the outlet of the air shower head is 1000-3000 m³ / h. 3 / h.

[0039] In one or more specific embodiments of this utility model, both outlet 10 and inlet 11 are equipped with electrically controlled automatic doors. Those skilled in the art should know that these electrically controlled automatic doors are existing equipment.

[0040] Example 2

[0041] While Example 1 addresses the shortcomings of existing air showers, making entry and exit more convenient, cleanrooms in medical institutions are used for various purposes—either surgery, imaging, or both. When imaging equipment is present in a cleanroom, the clarity of the resulting images varies, and image quality is crucial for the attending physician. Research has revealed that the inconsistent image clarity in cleanroom imaging equipment is related to the personnel entering the room. Entering an air shower only removes dust; personnel bring moisture into the cleanroom, causing unstable moisture content in the air surrounding the imaging equipment, ultimately affecting the photosensitive materials used in the imaging equipment.

[0042] Please refer to Figure 1, Figures 3-5 , Figure 4 This is a schematic cross-sectional view of the air shower chamber in this embodiment. Figure 5 This is a schematic diagram showing the location of the water absorption device of this utility model.

[0043] An air shower device includes an air shower chamber 1 and a cleanroom 2. The air shower chamber 1 is located inside the cleanroom 2. The air shower chamber 1 includes a front wall 17, a left side wall 18, a right side wall 5, a rear wall 19, a floor 3, and a ceiling 4. An inlet 11 is provided on the front wall 17, and an outlet 10 is provided on the rear wall 19. The outlet 10 communicates with the cleanroom 2. A first partition 6, a second partition 7, and a third partition 8 are provided between the front wall 17 and the rear wall 19 inside the air shower chamber 1. The first partition 6, the second partition 7, and the third partition 8 are equidistant. The width of the first partition 6, the second partition 7, and the third partition 8 is smaller than the width of the front wall 17 or the rear wall 19. The first partition 6, the second partition 7, and the third partition 8 form a progressive purification channel 12 between the inlet 11 and the outlet 10 inside the air shower chamber 1. The progressive purification channel 12 consists of a first forward purification channel 13, a first reverse channel 14, a second forward channel 15, and a second reverse channel 16. The first forward purification channel 13 is connected to the inlet 11, and the second reverse channel 16 is connected to the outlet 10. The first forward purification channel 13 turns at the left wall 18 to enter the first reverse channel 14. The first reverse channel 14 turns at the right wall 5 to enter the second forward channel 15. The second forward channel 15 turns at the left wall 18 to enter the second reverse channel 16. Air shower nozzles (not shown in the figure) are installed on the front wall 17, left wall 18, right wall 5, rear wall 19, ceiling 4, first partition 6, second partition 7, and third partition 8 to blow away dust particles and other particles and produce clean airflow.

[0044] On the one hand, by setting up the first partition 6, the second partition 7, and the third partition 8, a first forward purification channel 13, a first reverse channel 14, a second forward channel 15, and a second reverse channel 16 are formed. This allows the person being purified to enter through the inlet 11 and then walk through the first forward purification channel 13. Upon reaching the left wall 18, they turn into the first reverse channel 14, and so on, being purified as they walk. The cleanliness level increases throughout the walking process, reaching its highest level at the outlet 10. The entire purification process is essentially a walking process, making it easy and convenient, especially suitable for children and the elderly. On the other hand, replacing the original partition curtain with the first partition 6, the second partition 7, and the third partition 8 increases the installation direction of the air shower nozzles (the partition curtain needs to be opened, and the curtain itself prevents the installation of air shower nozzles, thus eliminating the cleaning effect in that direction). This increases purification from the partition direction, effectively achieving full-body, leak-free purification and improving the overall purification effect.

[0045] The air shower chamber 1 is also equipped with a fourth partition 9, which is located between the third partition 8 and the rear wall 19, forming a drying channel 21. After the person being cleaned has finished, they enter the drying channel 21 through the second reverse channel 16 to remove any moisture they carry, preventing the introduction of excessive moisture into the cleanroom. Those skilled in the art should note and understand that the drying in the drying channel 21 should remove moisture appropriately to ensure human comfort, without causing discomfort. Excess moisture can typically be removed using hot air or by placing absorbent materials that can absorb moisture from the air. When using hot air, the fourth partition 9 is equipped with air shower nozzles that emit hot air; in this case, the air emitted from the nozzles in the drying channel 21 is hot air.

[0046] By setting up the drying channel 21, excess moisture brought in from the outside of the body is removed, thus preventing the imaging equipment from having inconsistent image quality, which could affect the attending physician's judgment of the patient's condition.

[0047] In one or more specific embodiments of this utility model, a water absorption device 22 is provided inside the drying channel 21. The water absorption device 22 contains an absorbent, which can be quicklime. Quicklime can absorb moisture from the air and also kill bacteria and viruses. The absorption device 22 can be installed on the rear wall 19. Those skilled in the art should understand that, to prevent the quicklime from being blown away by the wind, the quicklime should be in block form, and during application, the moisture content of the block quicklime should be checked regularly and replaced as needed to avoid safety risks.

[0048] In one or more specific embodiments of this utility model, the right end of the first partition 6 is connected to the right side wall 5, and the distance H1 between its left end and the left side wall 18 is 300mm to 600mm. The left side of the second partition 7 is connected to the left side wall 18, and the right end is connected to the right side wall 5, with a distance H2 of 300mm to 600mm. The right end of the third partition 8 is connected to the right side wall 5, and the distance H3 between its left end and the left side wall 18 is 300mm to 600mm. This 300mm to 600mm spatial distance setting avoids discomfort for the person being purified, while also preventing the space from being too large, which could affect the purification effect and increase permissible costs.

[0049] In one or more specific embodiments of this utility model, the widths of the first forward purification channel 13, the first reverse channel 14, the second forward channel 15, and the second reverse channel 16 are 300mm to 600mm. This 300mm to 600mm width setting avoids discomfort for the person being purified, while also preventing the space from being too large, which could affect the purification effect and increase permissible costs.

[0050] In one or more specific embodiments of this utility model, the width of the outlet 10 and the inlet 11 is 300mm to 600mm.

[0051] In one or more specific embodiments of this utility model, the first partition 6, the second partition 7, and the third partition 8 are all purification plates.

[0052] In one or more specific embodiments of this utility model, the air volume at the outlet of the air shower head is 1000-3000 m³ / h. 3 / h.

[0053] In one or more specific embodiments of this utility model, both the outlet 10 and the inlet 11 are equipped with electrically controlled automatic doors.

[0054] This invention also provides a method for entering an operating room or ICU. The method utilizes the aforementioned air shower device. Before an outsider enters the operating room or ICU, the electrically controlled automatic door of inlet 11 opens. The outsider first passes through a progressive purification channel 12 for purification, a walking purification process. Then, they enter a drying channel 21 to remove some moisture. Finally, the electrically controlled automatic door of outlet 10 opens, allowing them to enter the operating room or ICU. The entire process is relatively comfortable, and the drying channel 21 ensures that the moisture content carried by personnel entering the operating room or ICU remains constant, thereby improving the quality of imaging equipment.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
