However, the conventional operating room has the following problems.
In other words, in the hybrid type operating room, compared to a room where only treatment is performed, large-scale devices necessary for surgery are provided around the operating table, and these devices are also supported on the ceiling above the operating table. Or equipment for moving. For example, a large device such as an X-ray that can move along the patient on the operating table is arranged around the operating table. In this case, a rail for moving the X-ray machine along the longitudinal direction of the operating table is extended on the ceiling portion above the operating table. Since many such devices are provided in the ceiling portion, the position of the blow-out port that blows clean air is also arranged at a position that avoids these devices.
For this reason, the outlet is located at a position away from the upper part of the operating table, and the blown clean air cannot be supplied locally and reliably to the patient on the operating table, and there is room for improvement in that respect. .

The present invention has been made in view of the above-described problems, and uses an outlet filter unit capable of locally supplying clean air to a desired position by adjusting the direction of the outlet . The purpose is to provide a clean room .

To achieve the above object, in a clean room blown with mouth filter unit according to the present invention, blown from the air outlet provided with air blown out from the fan to the chamber wall towards the desired position blow mouth filter unit A clean room in which the air outlet filter unit is disposed on the ceiling and supplies clean air blown out from the air outlet of the air outlet filter unit toward the supplied portion, the air outlet filter unit Comprises a filter and a tiltable two-stage direction adjusting blade disposed on the outlet side of the filter and overlapping along the outlet direction, and the first direction adjusting blade on the upstream side of the direction adjusting blade. The first rotation shaft and the second rotation shaft of the second direction adjustment blade on the downstream side are arranged in different directions, and the first direction adjustment blade Preliminary second direction adjusting vanes about their respective rotary shafts rotatably provided at a desired angle, the blowing mouth filter unit, the air outlet is deviated from the portion just above the target supply unit The first direction adjusting blade and the second direction adjusting blade are tilted at an inclination angle at which the first direction adjusting blade and the second direction adjusting blade can be blown toward the supplied portion, and the ceiling is provided on both sides of the air outlet filter unit. And a second filter unit that blows out air at a position between the outlet filter unit and the side wall of the chamber, and a suction port is disposed below the side wall of the chamber. It is characterized by being.

In the present invention, the blowing direction can be adjusted in two directions by tilting the upper first direction adjusting blade and the lower second direction adjusting blade with an appropriate inclination angle. Clean air can be locally supplied toward the supplied part located in a desired direction.
In addition, since the two-stage direction adjustment blades are provided downstream of the filter at the outlet, the clean air having the directionality by the two-stage direction adjustment blades set at a predetermined angle passes through the filter. There is nothing. Therefore, since the clean air that has passed through the direction adjustment blades is directly blown out from the outlet, the clean air is rectified and the directionality can be improved.

Since the upper first direction adjustment blade and the lower second direction adjustment blade are separated into two stages, efficient supply of clean air can be achieved by setting each blade individually at an appropriate inclination angle. It can be performed.
In this case, the clean air (first clean air) blown out from the outlet filter unit toward the supplied portion is the clean air (second clean air) blown out directly from the second filter unit. ), The air flow of the first clean air can be prevented from being disturbed before reaching the supplied portion. Therefore, the required air volume and directionality blown out from the outlet filter unit are stabilized, and local supply toward the supplied portion can be performed more reliably.

In the clean room using the outlet filter unit according to the present invention, it is preferable that the axial direction of the first rotating shaft and the axial direction of the second rotating shaft are orthogonal to each other.

  In this case, the clean air that has passed through the upper first direction adjustment blade can be blown out in the direction orthogonal to the lower second direction adjustment blade.

According to the clean room using the blowout port filter unit of the present invention, the clean air that has passed through the two-stage direction adjusting blades of the blowout port filter unit is directed to a predetermined direction without passing through the filter. Therefore, it is possible to supply clean air locally to the supply target portion at a desired position.

Two guide rails 3 (3A, 3B) for running equipment such as X-rays are installed. As shown in FIGS. 1 and 2, the guide rail 3 is arranged in parallel along the longitudinal direction of the operation table 2 on the ceiling 1 a.
In plan view, the direction along the longitudinal direction of the guide rail 3 is defined as the X direction, and the direction orthogonal to the X direction is defined as the Y direction.

  The clean room 1 includes two pairs of first filter units 10 (10A, 10B) that supply the first clean air E1 toward the upper surface (patient) of the operation table 2, and the first filter units 10A on the ceiling 1a. 10B, two second filter units 20 (20A, 20B) arranged on the outer side in the arrangement direction (Y direction), and a suction port 4 arranged on the side wall 1b of the room.

Here, a schematic configuration of the air conditioning system employed in the clean room 1 will be described with reference to FIG.
FIG. 4 shows one each of the first filter unit 10 and the second filter unit 20. Specifically, the air is supplied to the air conditioner 33 by the air supply fan 32 through the first prefilter 31, and the room is passed through the first filter unit 10 and the second filter unit 20 by the air supply fan 34 in the air conditioner 33. Clean air E1, E2 is sent to R. Here, the code | symbol 35 is equipped with the temperature / humidity setting device, the control panel which controls the air conditioner 33, and the code | symbol 36 has shown the operation room.
The clean air E1 and E2 sent from the first filter unit 10 and the second filter unit 20 are exhausted from the operation chamber 36 and the suction port 4. The air exhausted from the suction port 4 is returned to the air conditioner 33 through the second prefilter 37 and is sent to the filter units 10 and 20. The air conditioner 33 is provided with a cooling coil and a humidifier (not shown), and is also connected to the outdoor unit 38.

  As shown in FIGS. 5 and 6, the first filter units 10 </ b> A and 10 </ b> B are arranged on the outlet side of the filter 11 and the filter 11, and can be tilted and overlapped along the blowing direction. , 13 and the first rotation axis C1 of the upstream first direction adjustment blade 12 and the second rotation axis C2 of the downstream second direction adjustment blade 13 are directed in different directions. Are arranged. The first filter units 10A and 10B are arranged at positions on both sides of the two guide rails 3A and 3B in the Y direction in a plan view and shifted outward from the position directly above the operation base 2 in the Y direction. Has been.

As the filter 11, a high performance filter (HEPA (High Efficiency Particulate Air)) is employed.
The direction adjusting blades 12 and 13 are configured to be rotatable (tiltable) to a desired angle around the respective rotation axes C1 and C2. The first direction adjusting blades 12 are arranged with the first rotation axis C1 directed in the Y direction, and a plurality of single blade members 12A, 12A,... Are arranged in the same direction (here, the X direction). The second direction adjusting blades 13 are arranged with the second rotation axis C2 facing the X direction, and a plurality of single blade members 13A, 13A,... Are arranged in the same direction (here, the Y direction). The first rotation axis C1 of the first direction adjustment blade 12 and the second rotation axis C2 of the second direction adjustment blade 13 are orthogonal to each other. That is, in the first filter unit 10, the direction of the first direction adjustment blade 12 in the upper stage is rotated to adjust the blowing direction in the X direction, and the direction of the second direction adjustment blade 13 in the lower stage is rotated. Thus, the blowing direction in the Y direction can be adjusted.

  Note that the configuration of the number of blade members 12A and 13A of each of the direction adjustment blades 12 and 13, the arrangement interval (pitch), the rotatable inclination angle, and the like are appropriately determined according to conditions such as the size of the room and the amount of processing air flow. It can be set.

  The second filter units 20A and 20B shown in FIGS. 1 and 2 are arranged on both sides of the two first filter units 10A and 10B in the Y direction, and the direction adjusting blades of the first filter units 10A and 10B described above. 12 and 13 are omitted, and only the filter is provided. Other configurations are the same, and thus detailed description thereof is omitted here.

Next, the effect | action of the clean room using the filter unit for outlets which consists of an above-described structure is demonstrated based on drawing.
As shown in FIGS. 1 and 2, in the present clean room 1, the first clean air E <b> 1 that is blown out from the outlet 14 of the first filter units 10 </ b> A and 10 </ b> B flows toward the upper surface 2 a of the operating table 2. Furthermore, at this time, the second clean air E2 is also blown out from the outlets 21 of the two second filter units 20A and 20B in the direction directly below. At this time, the 1st clean air E1 by 1st filter unit 10A, 10B will be in the state enclosed from the outer side by the 2nd clean air E2, and the air current of the 1st clean air E1 will be disturbed before reaching the operation stand 2. Can be suppressed. Therefore, the necessary air volume and directionality blown out from the first filter units 10A and 10B are stabilized, and local supply toward the operation base 2 can be performed more reliably (see FIG. 7).

  As described above, in the first filter units 10A and 10B of the present embodiment, the upper direction first direction adjustment blade 12 and the lower second direction adjustment blade 13 are tilted at an appropriate inclination angle to thereby change the blowing direction to 2. Since it is possible to adjust in the direction (X direction, Y direction), the first clean air E1 blown out from the blowout port 14 is directed toward the upper surface 2a of the operation base 2 which is a supplied portion located in a desired direction. Can be supplied locally. Thereby, the top of the operating table 2 can be reliably cleaned.

In addition, since the two-stage direction adjusting blades 12 and 13 are provided downstream of the filter 11 at the outlets 14 of the first filter units 10A and 10B, the two-stage direction adjusting blades set at a predetermined angle are provided. The first clean air E <b> 1 given directionality by 12, 13 does not pass through the filter. Therefore, since the 1st clean air E1 which passed the direction adjustment blade | wings 12 and 13 is directly blown out from the blower outlet 14, clean air E1 is rectified and directionality can be improved.
Furthermore, since the first directional adjustment blade 12 on the upper stage and the second directional adjustment blade 13 on the lower stage are separated into two stages, respectively, by setting the respective blades 12 and 13 individually at appropriate inclination angles, Efficient clean air can be supplied.
