Hereinafter, embodiments of the present disclosure will be described based on the drawings. Note that the present disclosure is not limited to the following embodiments, and design changes can be made as appropriate within the scope of satisfying the configuration of the present disclosure. Further, in the following description, the same reference numerals are used in common for the same parts or parts having similar functions in different drawings, and the repeated description thereof will be omitted. Also, each configuration described in the embodiment and modifications may be appropriately combined or changed. Also, in order to make the explanation easier to understand, in the drawings referred to below, the configuration is shown in a simplified or schematic form, or some constituent members are omitted.

[First embodiment]
FIG. 1 is a cross-sectional view showing the configuration of a movable front chamber 100 according to this embodiment. The movable front chamber 100 is arranged at the entrance/exit 101 a of the negative pressure chamber 101 . The negative pressure room 101 is, but is not limited to, a treatment room, a sick room, and a room in a hospital, a school, a hotel, a nursing facility, or the like, where the indoor air pressure is made negative. Also, the negative pressure room 101 is a room in which a patient with an infectious disease or a person suspected of having an infectious disease resides. A plurality of wheels 40 are provided in the mobile front chamber 100 . Accordingly, by moving the mobile front chamber 100, it is possible to attach it to various negative pressure chambers 101 that are not equipped with front chambers. For example, the mobile front room 100 is arranged in the corridor 102 facing the entrance 101 a of the negative pressure room 101 . In the following description, the X1 direction and the X2 direction are the directions in which the corridor 102 extends, the Y1 direction and the Y2 direction are the width directions of the corridor 102, and the Z1 direction and the Z2 direction are the height directions. The Y1 direction indicates the direction away from the negative pressure chamber 101, the Y2 direction indicates the direction toward the negative pressure chamber 101, the Z1 direction indicates the upward direction, and the Z2 direction indicates the downward direction. Note that the movable anteroom 100 of the present disclosure is not limited to being used as the anteroom of the negative pressure chamber 101, and may be placed at the entrance/exit of a non-negative living room or hospital room. Even in this case, the movable front room 100 can prevent contaminated air from leaking out of the living room.

As shown in FIG. 1, the movable front chamber 100 includes a frame body 10, a sheet material 20, and fixing members 31 and 32 (see FIG. 5). The frame body 10 forms an internal space R of the mobile front chamber 100 . In the internal space R, a person (medical staff, etc.) P who enters and exits the negative pressure chamber 101 can perform work (for example, putting on and taking off protective clothing) when entering and exiting the negative pressure chamber 101 .

FIG. 2 is a perspective view for explaining the configuration of the frame body 10. FIG. FIG. 3 is a schematic plan view for explaining the arrangement relationship between the negative pressure chamber 101 and the movable front chamber 100. As shown in FIG. As shown in FIG. 2 , the frame body 10 includes multiple column members 11 , multiple longitudinal beam members 12 , and multiple lateral beam members 13 . A plurality of pillar members 11, a plurality of longitudinal beam members 12, and a plurality of lateral beam members 13 are combined to form a plurality of frames (six surfaces), so that the frame body 10 has a rectangular parallelepiped shape. formed. Thus, as shown in FIG. 3, the frame body 10 is formed with one side surface 10a and the other side surface 10b in the short direction, and one side surface 10c and the other side surface 10d in the longitudinal direction.

As shown in FIG. 3, the frame body 10 has a rectangular shape in plan view. That is, the length L1 in the longitudinal direction of the frame body 10 (movable front chamber 100) is greater than the length (width) W1 in the lateral direction. Note that the width W1 is smaller than the width W2 of the corridor. The movable front room 100 is arranged so that the longitudinal direction of the frame body 10 and the direction in which the corridor 102 extends are parallel, and the lateral direction of the frame body 10 and the width direction of the corridor 102 are parallel. be. A doorway 51 is provided on the side surface 10a on the movable front chamber 100 side. A doorway 52 is provided on the side 10b on the corridor 102 side. Here, the width of corridors in hospitals and nursing homes must have a predetermined width (Medical Law Enforcement Regulations, Article 16, Paragraph 1, Item 11). In addition, even in facilities other than hospitals and nursing care facilities (such as schools), the lower limit of the width of corridors is stipulated by the Building Standards Law. Therefore, by arranging the movable front room 100 in a state in which the short direction of the movable front room 100 is aligned with the width direction of the corridor 102 as described above, the width direction of the movable front room 100 in the corridor 102 It is possible to secure a large internal space R of the movable front room 100 along the direction in which the corridor 102 extends, while reducing the ratio of .

The entrance/exit 51 is, for example, an opening that communicates with the entrance/exit 101 a of the negative pressure chamber 101 . That is, when the doorway 51 is provided at the doorway 101 a of the negative pressure chamber 101 , the door is shared by the movable front chamber 100 and the negative pressure chamber 101 . As a result, since a plurality of doors are not arranged at the entrance 101a of the negative pressure chamber 101, the person P who enters and exits does not need to open and close a plurality of doors. Moreover, the configuration of the mobile front chamber 100 can be simplified and the weight thereof can be reduced. In addition, in the present disclosure, what is shared is not limited to the door, and the side surface of the negative pressure chamber 101 side of the movable front chamber 100 and the outer wall portion 101b may be shared without providing the side surface 10a to the frame body 10. . That is, the surface of the movable front chamber 100 in contact with the negative pressure chamber 101 may be formed as a baseless U-shaped frame.

As shown in FIG. 3, the doorway 52 is formed at a position shifted from the doorway 51 in the X1 direction (longitudinal direction). Specifically, the longitudinal center C2 of the doorway 52 is located in the X1 direction from the longitudinal center C1 of the doorway 51 . According to this configuration, the doorway 52 and the doorway 101a of the negative pressure chamber are displaced in the longitudinal direction, so that the path through which the air A flows between the doorway 101a of the negative pressure chamber 101 and the doorway 52 can be complicated. As a result, contaminated air from the negative pressure chamber 101 can be prevented from exiting the entrance 52 through the movable front chamber 100 .

Also, as shown in FIG. 2 , the mobile vestibule 100 includes a doorway sheet material 60 suspended over the doorway 52 . The entrance/exit sheet material 60 includes a plurality of sheet materials 61 arranged side by side in the X1 direction. The sheet material 61 has flexibility. That is, the entrance/exit sheet material 60 is formed in a so-called noren shape. Thus, unlike the case where the doorway 52 is provided with a door, the doorway sheet member 60 allows easy entry into and exit from the internal space R of the frame body 10 without using hands. By not touching the entrance/exit sheet material 60 with hands, the entrance/exit sheet material 60 can be maintained in a good sanitary condition.

Moreover, as shown in FIG. 1, the sheet material 20 is arranged so as to cover at least a portion of the frame body 10 . Specifically, the sheet material 20 covers the side surfaces 10b, 10c, and 10d (see FIG. 3) and the top surface 10e (see FIG. 2) of the frame body 10. As shown in FIG. 2, illustration of the sheet material 20 is omitted. The sheet material 20 has flexibility. The sheet material 20 is made of, for example, soft vinyl chloride, although not limited thereto. The sheet material 20 also includes a skirt portion 21 . The skirt portion 21 is fixed (attached) to the outer wall portion 101b near the entrance/exit 101a of the negative pressure chamber 101 by fixing members 31 and 32 (see FIG. 5). As a result, it is possible to prevent contaminated air from leaking from the negative pressure chamber 101 through the gap between the movable front chamber 100 and the negative pressure chamber 101 . Incidentally, the side surfaces 10b, 10c, 10d and the top surface 10e may be provided with an acrylic plate, or may be composed of the sheet material 20 alone.

FIG. 4 is a front view of the doorway 101a of the negative pressure chamber 101 and the vicinity of the doorway 101a. The term "nearby" means the range from the doorway 101a to the ceiling of the negative pressure room 101 and from the doorway 101a to the doorway of the next living room. As shown in FIG. 4, magnetic members 50 are arranged along the outer edges 101c and 101d of the doorway 101a. The magnetic member 50 is arranged in a U-shape (U-shape) opening downward when viewed in the Y2 direction. The magnetic member 50 is made of, but not limited to, an iron plate.

FIG. 5 is a diagram for explaining the configuration of the skirt portion 21 and the fixing members 31 and 32. As shown in FIG. As shown in FIG. 5, the skirt portion 21 is arranged to extend upward (Z1 direction) and laterally (X1 direction and X2 direction) from the frame body 10 . A fixing member 31 is fixed to a portion of the skirt portion 21 above the frame body 10 . A fixing member 32 is fixed to each portion of the skirt portion 21 in the left-right direction relative to the frame body 10 . The fixing members 31 and 32 are, for example, permanent magnets. The skirt portion 21 of the sheet material 20 is fixed to at least a portion of the outer wall portion 101b by magnetically attracting the fixing members 31 and 32, which are permanent magnets, to the magnetic member 50 (iron plate).

As shown in FIGS. 4 and 5, the length (width) W11 of the magnetic member 50 is greater than the width W21 of the fixed member 31 in the outward direction (Z1 direction) from the outer edge portion 101c. In addition, the length (width) W12 of the magnetic member 50 is greater than the width W22 of the fixed member 32 in the direction (X1 direction or X2 direction) further outward from the outer edge portion 101d. According to this configuration, when the movable front chamber 100 is misaligned with respect to the entrance 101a of the negative pressure chamber 101, or the dimensions of the entrance 101a of the negative pressure chamber 101 and the dimensions of the movable front chamber 100 are different. Even in this case, since the widths W11 and W12 of the magnetic member 50 are large, the fixing members 31 and 32 can be attracted to the magnetic member 50 by absorbing deviations and dimensional differences.

According to the above configuration, leakage of contaminated air from the negative pressure chamber 101 can be prevented, and a space for a person P who enters and exits the negative pressure chamber 101 to put on and take off protective clothing can be secured.

[Second embodiment]
The configuration of the movable front chamber 200 in the second embodiment will be described with reference to FIGS. 6 to 8. FIG. FIG. 6 is a cross-sectional view of the mobile front chamber 200 in the second embodiment. FIG. 7 is a perspective view of the frame body 210 in the second embodiment. FIG. 8 is a schematic plan view showing the arrangement relationship between the movable front chamber 200 and the negative pressure chamber 101. As shown in FIG. In the second embodiment, the movable front chamber 200 is configured such that the stretcher S can enter and exit the negative pressure chamber 101 through the movable front chamber 200 . In addition, the same code|symbol as 1st Embodiment is used for the structure similar to 1st Embodiment, and description is abbreviate|omitted.

As shown in FIG. 6, the movable front chamber 200 has a dimension that allows the stretcher S to be arranged. For example, as shown in FIG. 8, the longitudinal length L31 of the frame body 210 of the mobile front chamber 200 is longer than the longitudinal length L32 of the stretcher S, and the frame body 210 of the mobile front chamber 200 The length W31 of the stretcher S in the transverse direction is greater than the length W32 of the stretcher S in the transverse direction. Further, in the second embodiment, a doorway 252 is provided on the longitudinal side surface 10d of the frame body 210. As shown in FIG. This allows the stretcher S to move in and out of the movable front chamber 200 along the longitudinal direction. Further, as shown in FIGS. 7 and 8, the longitudinal beam member 12 and the lateral beam member 13 are not provided on the traveling path E of the stretcher S. As shown in FIGS. Thereby, the stretcher S can smoothly move in and out of the movable front chamber 200 without getting over the longitudinal beam members 12 and the lateral beam members 13 . A doorway sheet member 260 is provided at the doorway 252, and the plurality of sheet members 61 of the doorway sheet member 260 are arranged side by side in the Y1 direction.

According to the configuration of the second embodiment, the movable front chamber 200 can also be used when moving the stretcher S into and out of the negative pressure chamber 101 . In addition, since the doorway 252 and the doorway 51 do not face each other, the air flow path between the doorway 101a of the negative pressure chamber 101 and the doorway 252 can be complicated. As a result, leaking of contaminated air from the negative pressure chamber 101 can be prevented also in the second embodiment. Other configurations and effects are the same as those of the first embodiment.

This filter is, for example, a HEPA filter. Accordingly, even if contaminated air exists in the movable front chamber 300, it is possible to prevent the contaminated air from leaking to the outside. Other configurations and effects are the same as those of the first embodiment.

[Fourth embodiment]
The configuration of the movable front chamber 600 in the fourth embodiment will be described with reference to FIGS. 12 to 14. FIG. FIG. 12 is a cross-sectional view of the position where the sheet material 620 is arranged in the movable front chamber 600 in the fourth embodiment. FIG. 13 is a cross-sectional view of the position where the doorway sheet member 660 is arranged in the movable front chamber 600 in the fourth embodiment. FIG. 14 is a cross-sectional view of a state in which the movable front chamber 600 is moved according to the fourth embodiment. Note that the same reference numerals as in the first to third embodiments are used for the same configurations as those in the first to third embodiments, and descriptions thereof are omitted.

As shown in FIG. 12 , movable front chamber 600 includes frame body 610 and sheet material 620 . Each column member 611 of the frame body 610 includes an expansion mechanism 611a that changes the dimension of the column member 611 in the height direction. For example, the column member 611 has a rectangular tubular shape. The pillar member 611 includes an upper pillar 611b and a lower pillar 611c having sides with different lengths. For example, the expansion mechanism part 611a fixes the upper pillar 611b and the lower pillar 611c in a state in which a part of the upper pillar 611b is arranged inside the lower pillar 611c. The expansion and contraction mechanism 611a can be operated by the user to fix (lock) the relative positions of the upper pillar 611b and the lower pillar 611c, and to allow the upper pillar 611b and the lower pillar 611c to move relatively (unlocked). state) and As a result, the dimension in the height direction of the column member 611 becomes the maximum dimension when the upper column 611b is pulled out from the lower column 611c to the maximum. For example, the height of the upper surface of the frame body 610 is h1. Here, when the height of the entrance 601a of the negative pressure chamber 601 is h3, the entrance 601a can be covered with the movable front chamber 600 if the height h1 is h3 or more, as shown in FIG.

Then, the sheet member 620 has a surplus portion 623 that is at least a portion of the sheet member 620 other than the portion 622 that covers the frame body 610 in a state where the dimension in the height direction of the column member 611 is less than the maximum dimension. include. In addition, in the fourth embodiment, the sheet material 620 has a surplus portion 623 even if the dimension in the height direction of the column member 611 is the maximum dimension. The length of the surplus portion 623 along the column member 611 increases as the dimension in the height direction of the column member 611 decreases, and the length along the column member 611 increases as the dimension in the height direction of the column member 611 increases. length becomes smaller. The surplus portion 623 is detachably fixed to the outer surface of the portion 622 by hook-and-loop fastener 623a, for example. The portion 622 is formed so that the hook-and-loop fastener 623a can be fixed at an arbitrary position on the outer surface of the portion 622 . As a result, the surplus portion 623 is arranged in a folded state with respect to the portion 622 . Although illustration is omitted, the surplus portion 623 of the sheet material 620 is folded back on the portion 622 not only on the side surface in the Y1 direction of the frame body 610 but also on the side surface in the X1 direction and the side surface in the X2 direction. placed in a state.

As shown in FIG. 13 , the entrance/exit sheet material 660 has a height dimension smaller than the maximum dimension of the column member 611 , and at least a part of the entrance/exit sheet material 660 other than the part 662 covering the entrance/exit 52 is removed. It contains a surplus portion 663 where . In addition, in the fourth embodiment, the entrance/exit sheet material 660 has a surplus portion 663 even if the dimension in the height direction of the column member 611 is the maximum dimension. The length of the surplus portion 663 along the column member 611 increases as the dimension in the height direction of the column member 611 decreases, and the length along the column member 611 increases as the dimension in the height direction of the column member 611 increases. length becomes smaller. The surplus portion 663 is detachably fixed to the outer surface of the portion 662 by hook-and-loop fastener 663a, for example. The portion 662 is formed so that the hook-and-loop fastener 663a can be fixed at an arbitrary position on the outer surface of the portion 662 . As a result, the surplus portion 663 is arranged in a folded state with respect to the portion 662 .

Here, as shown in FIG. 14, when the mobile front room 600 is moved, it may be necessary to pass through a doorway 602 having a height h4 that is less than h1 in the facility. At this time, according to the movable front chamber 600 according to the fourth embodiment, by setting the height of the frame body 610 to h2, which is smaller than h4, the doorway 602 can be moved without dismantling the movable front chamber 600. It can pass through the mobile vestibule 600 . Here, since the height of the frame body 610 becomes h2 which is smaller than h4, the side surface 610a arranged on the entrance/exit 601a (see FIG. 12) side of the negative pressure chamber 601 is covered with the portion 624 of the sheet material 620. For example, when the frame body 610 has a predetermined height (for example, minimum height), the entire side surface 610 a is covered with the portion 624 . That is, when the dimension in the height direction of the column member 611 is a predetermined dimension (for example, the minimum dimension), the entire side surface 610a is covered with the portion 624 . As shown in FIG. 12, when the dimension of the column member 611 in the height direction is larger than a predetermined dimension (for example, the minimum dimension), the side 610a is open. That is, the side surface 610 a is closed when the movable front chamber 600 is moved, and is open when attached to the negative pressure chamber 601 . Also, the portion 624 is detachably fixed to the beam member 612 of the frame body 610 by the fixing member 31 . In addition, since the movable front room 600 can pass through the doorway 601 a , the movable front room 600 can be arranged at the doorway 601 a inside the negative pressure room 601 instead of the corridor 102 . As a result, it is possible to prevent traffic in the hallway 102 from being blocked by the movable front room 600 . Other configurations and effects of the fourth embodiment are the same as those of any one of the first to third embodiments.
