For example, the vertical support bar 2d is configured such that one of the first vertical support bar 2d1 and the second vertical support bar 2d2 is fitted to the other, and the first vertical support bar 2d1 and the second vertical support bar After adjusting the overall length formed by 2d2, it is fixed by a fixing member (not shown).

Since the lengths of the vertical support bars 2b and 2d can be expanded and contracted, the height of the main body 2h can be adjusted according to the height of the seat, adults, children, and the like.
Of course, other configurations can be adopted as the mechanism for adjusting the length of the vertical support rods 2b and 2d.

  The main body 2h is attached to and supported by the upper portions of the vertical support bars 2b and 2d. As shown in FIGS. 1 (a) and 1 (b), the hood 3 is rotatably supported by the main body 2h.

<Food 3>
As shown in FIG. 1 (a), the hood 3 is pulled up from the first state covering the heads p1a and p2a of the patients p1 and p2 and the state shown in FIG. 1 (a), and is shown in FIG. 1 (b). Thus, it is the structure which can be rotated to the 2nd state which open | releases the heads p1a and p2a of the patients p1 and p2 (arrow (beta) 1, (beta) 2 of FIG. 1 (a), (b)).

  The hood 3 is formed of a transparent or translucent material, and is defined for each patient p1, p2,. Since the hood 3 is transparent or translucent, as shown in FIG. 1A, the surroundings can be visually observed even when the patients p1, p2,. The person can also visually observe the states of the patients p1 and p2.

The hood 3 includes a flat plate-like first side plate 3a that forms one side edge, a flat plate-like second side plate 3b that forms the other side edge, a substantially partial circumferential top plate 3c, and each person It has flat partition plates 3d1, 3d2, and 3d3 that partition each space.
The hood 3 is manufactured by injection molding as a whole with a transparent resin, or by partially injection molding and joining or bonding to each other by fusion or the like.

  Alternatively, the connecting portion of the first side plate 3a, the second side plate 3b, the top plate 3c, and the partition plates 3d1, 3d2, 3d3 is manufactured with a metal frame, and the first side plate 3a, the second side plate 3b, the top plate are attached to the metal frame. 3c and partition plates 3d1, 3d2, 3d3 may be fixed by screwing or the like. Since the hood 3 only needs to work to surround the heads p1a, p2a,... Of the patients p1, p2,..., High strength is unnecessary, and the metal frame is made of a thin stainless steel plate, aluminum plate, or the like. used.

The hood 3 is rotatably supported by a rotation shaft (not shown) provided in the main body 2h.
In a use state (see FIG. 1A) in which the hood 3 shown by the solid line in FIG. 2 surrounds (covers) the heads p1a, p2a,... Of the patients p1, p2,. It is in contact with the stopper and holds the position in use.

  On the other hand, in the unused state (see FIG. 1B) in which the hood 3 shown by the two-dot chain line in FIG. 2 opens the heads p1a, p2a,... Of the patients p1, p2,. A member (not shown) is elastically engaged, and the hood 3 is held at an unused position. For example, an engaging recess is formed in a part of the hood 3 and a convex holding member (not shown) urged by an elastic force so as to engage with the engaging recess of the hood 3 is formed on the main body 2h. It is configured.

When the hood 3 changes its position from the unused state in FIG. 1B, a convex holding member (not shown) is elastically retracted to engage the engaging recess of the hood 3. remove. In addition, the convex holding part urged by the elastic force may be formed on the hood 3 side, and the engaging concave part may be formed on the main body part 2h side.
The raising and lowering of the hood 3 may be performed manually by human power, or may be configured to automatically move using a motor and a speed reduction mechanism.

<Duct 4>
As shown in FIG. 1 (b), a suction port 4s for sucking air containing droplets emitted from the patients p1, p2,... Has been.

One end of the branch duct 4a is connected to the rear part of each suction port 4s, and air including droplets flowing from the suction port 4s flows into the branch duct 4a.
The other end of each branch duct 4 a is connected to the collecting duct 4 b, and the other end of the collecting duct 4 b is connected to the fan filter unit 5. As described above, the duct 4 includes the plurality of branch ducts 4a connected to the respective suction ports 4s and the aggregation duct 4b to which the plurality of branch ducts 4a are connected. Note that one end of the collecting duct 4b may or may not be connected to the suction port 4s.

Due to the configuration of this air flow (air path), the air containing the splash flows from the hood 3 through the respective intake ducts 4 s through the respective branch ducts 4 a and the collecting duct 4 b and flows into the fan filter unit 5. .
The duct 4 may have a rigid configuration using metal, resin, or the like, or may be a flexible duct that can be deformed.

<Fan filter unit 5>
As shown in FIG. 2, the fan filter unit 5 includes a filter 5a such as a HEPA filter or a medium performance filter that collects splashes including viruses, pathogens, molds, and the like, and a fan 5b that generates an airflow that sucks in air containing the splashes. And a power supply (not shown) and a power switch 5c.

The downstream part of the duct 4 is connected to the suction port 5 d of the fan filter unit 5.
When the power switch 5c of the fan filter unit 5 is turned on, the fan 5b is operated, and dirty air including a patient's splash is sucked through the duct 4, and the filter 5a removes viruses, pathogens, molds, and the like. Splashes contained are collected, and the purified air is discharged from the discharge port 5e of the fan filter unit 5 (see FIG. 1 (a), arrow α3 in FIG. 2).

<Use of infection control unit 1>
Next, how to use the infection control unit 1 will be described.
When the infection control unit 1 is not used, the power switch 5c of the fan filter unit 5 is “off”. When using the infection control unit 1, first, the power switch 5 c of the fan filter unit 5 is turned “ON”.

As shown in FIGS. 1 (a) and 2, when the patients p1 and p2 are seated on the chaise longue C1, the hood 3 is lowered manually or automatically (see arrow β1), and the heads p1a, p2a is covered with the hood 3.
As a result, the air in the hood 3 flows from the space in the hood 3 through each suction port 4s, each branch duct 4a, and the collective duct 4b by the suction force generated by the operation of the fan 5b of the fan filter unit 5. 5 is formed.

  Therefore, the air containing the droplets containing viruses, pathogens, molds, and the like when the patients p1 and p2 sneeze flows from the space in the hood 3 through the suction ports 4s, the branch ducts 4a, and the collecting duct 4b. The air is sucked into the fan filter unit 5. Then, in the fan filter unit 5, splashes containing viruses, pathogens, molds and the like are collected by the filter 5a, and the cleaned air is discharged from the discharge port 5e of the fan filter unit 5 (FIG. 1 (a)). ), See arrow α3 in FIG.

  As shown in FIG. 1 (b), when the patients p1 and p2 disappear, the hood 3 is raised, the power switch 5c of the fan filter unit 5 is turned off, and the operation of the fan filter unit 5 is stopped. The

According to the above configuration, since the droplets from the patients p1 and p2 sitting on the chaise longue C1 are collected by the air flow in the hood 3 in a waiting room of a medical institution or the like, infection due to the droplets emitted by the patients p1 and p2 is prevented in advance. Or it can be suppressed. Moreover, indoor air can be purified.
Furthermore, the total weight can be suppressed by adopting such a shape that the infection control unit 1 is put on a chaise longue C1 such as a waiting room.

Moreover, since it is the structure which isolates several persons simultaneously, the space for isolating one person can be reduced, and cost can be held down.
Therefore, it is possible to realize the infection control unit 1 that can surely collect the droplets, prevent the droplet infection, have a low weight per person to be isolated, and can be used for a long time at a low cost.
In addition, although the case where the food | hood 3 is for four people was illustrated, it cannot be overemphasized that the structure of the above-mentioned infection control unit 1 is applied, and how many people are used can be selected suitably.

<Modification 1 of Embodiment 1>
FIG. 3 (a) is a perspective schematic view showing a usage state of the infection control unit of the first modification of the first embodiment, and FIG. 3 (b) is an infection of the first modification of the first embodiment according to the present invention. It is a perspective schematic diagram which shows the unused state of a control unit.
Unlike the hood 3 of the first embodiment, the infection control unit 1A of the first modification of the first embodiment is configured to be foldable. Other configurations are the same as those of the first embodiment. These components are shown with the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 3B, the hood 3fa of the infection control unit 1A of Modification 1 is folded and stored when not in use, and when used, as shown in FIG. 3A, the patient p1 sits on a chaise longue C1. The p2 heads p1a and p2a are used so as to be lowered.

The hood 3fa is attached to the main body 2h of the frame 2 so as to be freely opened and closed.
The hood 3fa is flexible as well as a bone member 3c (3c1, 3c2, 3c3, 3c4) that is rotatably attached to the main body 2h, and a sheet member 3a1 that is fastened to the bone member 3c and is flexible like a cloth or a sheet. And a partition sheet member 3s1 that partitions users.

Each bone member 3 c is formed in a substantially U shape having an opening in the direction of the frame 2, and an end portion thereof is rotatably supported by the main body portion 2 h of the frame 2.
Since each bone member 3c needs strength to support the sheet member 3a1, it is formed of a thin rod-like member made of metal such as stainless steel. The bone members 3c1 to 3c4 may be formed of other materials such as resin as long as a predetermined strength can be ensured.

The sheet member 3a1 and the partition sheet member 3s1 are transparent or translucent sheet-like members made of flexible vinyl, thin resin, or the like.
As shown in FIG. 3B, when the hood 3fa is not used and is folded, a holding member (not shown) that holds the hood 3fa in the folded state is a main body portion of the frame 2. 2h. For example, the holding member has a shape that holds the hood 3fa in a folded state (unused state) such as an L shape, and is biased by an elastic material. The hood 3fa is configured to be movable so as to release or hold (hold) the hood 3fa when used or unused. The holding member may be configured to be fixed to a predetermined position with a lock member when the hood 3fa is not used or used.

  With the above-described configuration, the infection control unit 1A of the first modification is folded so as to be in close contact with the main body 2h of the frame 2 and held by the holding member when not in use, as shown in FIG. When the infection control unit 1A is used, as shown in FIG. 3A, the hood 3fa of the infection control unit 1A is removed (released) so as to cover the heads p1a and p2a of the patients p1 and p2. To be taken down.

  The bone member 3c (3c1, 3c2, 3c3, 3c4) is decelerated and moved by the rotational force of the motor, and the hood 3fa is folded in an unused state (see FIG. 3B) and in an expanded usage state ( 3 (a)) may be configured to be moved electrically. In this case, a gear portion having a different number of teeth is formed on each shaft support portion of each bone member 3c (3c1, 3c2, 3c3, 3c4), and the hood 3fa is folded by changing the reduction ratio from the motor. It is possible to synchronize the bone members 3c in operation and use operation of expanding the hood 3fa.

According to the infection control unit 1A of the first modification, when the hood 3fa is not used, the hood 3fa does not protrude outward because it is folded as shown in FIG. Therefore, it is excellent in handleability and usability when not in use.
Moreover, the effect of Embodiment 1 is show | played similarly.
Although the hood 3fa is exemplified for four persons, the number of persons can be selected as appropriate by applying the configuration of the infection control unit 1A.

<Modification 2 of Embodiment 1>
FIG. 4A is a perspective schematic view showing an unused state of the infection control unit of the second modification of the first embodiment, and FIG. 4B is a diagram of the infection control unit of the second modification of the first embodiment. It is a perspective schematic diagram which shows a use condition.

  FIG. 5 (a) is a side view of the infection control unit according to the second modification of the first embodiment as viewed from the side with the hood closed, and FIG. 5 (b) is a second modification according to the second modification of the first embodiment. It is the side view which looked at the state which opened the hood of the infection control unit from the side.

The infection control unit 1B according to the second modification of the first embodiment is different from the hood 3 according to the first embodiment in that the hood 3fb has the same foldable configuration as that of the first modification, and the bone members 3h1 and 3h2 are formed of two pieces. It is.
Since the other configuration is the same as that of the first embodiment, the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIG. 4A, the hood 3fb of the infection control unit 1B of Modification 2 is folded and stored when not in use, and when used, as shown in FIG. 4B, the patient p1 sitting on the chaise longue C1. , P2 heads p1a and p2a are respectively covered and used.

The hood 3fb is attached to the main body 2h of the frame 2 so as to be freely opened and closed.
The hood 3fb includes bone members 3h1 and 3h2 rotatably supported by the main body 2h, and a flexible sheet member 3b1 whose ends are fastened by the bone members 3h1 and whose center is fastened by the bone members 3h2. There is a partition sheet member 3s2 that is flexible and partitions users.

The sheet member 3b1 and the partition sheet member 3s2 are transparent or translucent sheet-like members made of flexible vinyl, thin resin, or the like.
The bone members 3h1 and 3h2 are formed in a substantially U shape having an opening in the direction of the frame 2, and an end portion of the substantially U shape is axially supported by the main body 2h of the frame 2 so as to be rotatable.

  FIG. 5 (a) is a side view of the infection control unit according to the second modification of the first embodiment as viewed from the side with the hood closed, and FIG. 5 (b) is a second modification according to the second modification of the first embodiment. It is the side view which looked at the state which opened the hood of the infection control unit from the side.

As shown in FIG. 5B, the bone member 3h2 is formed longer than the bone member 3h1. As a result, the bone member 3h2 can expand the sheet member 3b1 larger than the bone member 3h1, and the bone member 3h2 can secure a large space surrounding (covering) the heads p1a and p2a of the patients p1 and p2. Further, since the central space of the hood 3fb formed by the bone member 3h2 is wider than the entrance space of the hood 3fb formed by the bone member 3h1, the air in the hood 3fb can be easily retained.
Moreover, since the sheet | seat member 3b1 is expanded widely by the bone member 3h2, it can suppress that the patients p1 and p2 feel the tightness by the hood 3fb.

  Since the bone members 3h1 and 3h2 need strength to support the sheet member 3b1, the bone members 3h1 and 3h2 are formed of thin rod-like members made of metal such as stainless steel. Note that the bone members 3h1, 3h2 may be formed of other materials such as resin as long as a predetermined strength can be secured. Since the bone members 3h1 and 3h2 are smaller in number than the first modification, a larger load (mainly bending load) is applied, so the cross-section coefficient is set to a substantially L-shaped or substantially H-shaped cross section. It is preferable to make the structure strong against bending load.

  In addition, since the bone member 3h2 is longer than the bone member 3h1, as shown in FIG. 5A, when the hood 3fb is folded, the bone member 3h1 can be stored inside the bone member 3h2 and is bulky. Can be stored thinly. Therefore, even when the infection control unit 1B is not used, it is easy to use.

  Thereafter, as shown in FIG. 12 (b), the patient p1 sits on the chair C2, removes the holding member (not shown), widens the hood 53A, and covers the head p1a of the patient p1 with the hood 53A (FIG. 12 (a)). reference). Then, air including droplets due to coughing or sneezing of the patient p1 is sucked from the suction port 55A1 and flows into the main duct 54a through the branch duct 54b. Then, it is cleaned by the fan filter unit 5 and discharged from the discharge port 5e (see arrow α3 in FIG. 11A).

  Similarly, as shown in FIG. 11A, the patient p2 sits on the chair C3, removes the holding member (not shown), widens the hood 53B, and covers the head p2a of the patient p2 with the hood 53B. Then, the air including the droplets due to the coughing and sneezing of the patient p2 is sucked from the suction port 55B1 and flows into the main duct 54a. Then, it is cleaned by the fan filter unit 5 and discharged from the discharge port 5e (see arrow α3 in FIG. 11A).

  According to the infection control unit 51 of the fifth embodiment, the first infection control block 51A and the second infection control block 51B are movable according to the positions of the chairs C2 and C3, respectively. A control unit 51 can be used.

  In addition, since the heads p1a and p2a of the users (patients p1 and p2) are respectively covered with the hoods 53A and 53B, even if one or both of them cough or sneeze, the air containing the droplets is not absorbed into the suction ports 55A1 and 55A1. It is sucked in by the suction port 55B1, cleaned by the fan filter unit 55, and discharged from the discharge port 55e (see arrow α3 in FIG. 11A). Therefore, each user (patient p1, p2) can suppress or prevent the infection by the splash of others.

For example, if the user (patient p1) does not want to use the infection control unit 51, the hood 53A of the first infection control block 51A must be lowered as shown in FIGS. 11 (b) and 12 (b). Good. Similarly, if the user (patient p2) does not want to use the infection control unit 51, the hood 53B of the second infection control block 51B may not be lowered.
Moreover, the effect of the said Embodiment 1 is show | played similarly.
