Description

  The present invention relates to a local type clean air supply device capable of supplying high cleanliness air in a local range in a room.

  Products such as precision devices including semiconductors and sterilized medical devices that require an extremely high clean environment for manufacturing are manufactured in a clean room in which the entire indoor space is highly cleaned. Applications of clean rooms or air purifiers to achieve this are not limited to manufacturing equipment such as precision equipment, but are applied in medical settings (operating rooms, treatment rooms, etc.), for example. In some cases, the likelihood of an infection occurring during surgery or treatment can be significantly reduced.

  However, when an air cleaning device or the like is applied to an operating room or a treatment room for the purpose of avoiding infectious diseases, it is not always necessary to make the entire indoor space highly clean, and the target portion (becomes the target of surgery). It is sufficient if a high cleanliness space can be locally created within a certain range centered on the affected part or the part to be treated. From such a point of view, there is known an apparatus (local type clean air supply apparatus) that can supply clean air locally to a specific range instead of the entire indoor space.

  The local type clean air supply device cleans the air taken in from the room by using a HEPA filter or the like, and then blows it out in a certain direction. When the local type clean air supply device is operated, a high cleanliness space and other spaces coexist in the room. However, as a matter of course, those boundaries cannot be visually recognized. For this reason, there are the following problems.

  It can be considered that the space in front of the air outlet of the local clean air supply device, where the air is flowing vigorously, is a “high cleanliness space”. There is a possibility that existing dust or the like is involved and it cannot necessarily be said that the degree of cleanliness is high. Therefore, the high cleanliness space is a limited region (within a certain range from the center line of the air flow) further inside than the vicinity of the boundary of the air flow.

  When the local type clean air supply device is used to prevent infectious diseases that may occur during surgery or treatment, a certain range centered on the target portion such as an affected area is formed by the local type clean air supply device. It is necessary to adjust the blowing direction of clean air so that it is located inside the high cleanliness space, but as described above, the boundary between the high cleanliness space and the other spaces cannot be visually recognized. There is a problem that the adjustment work is complicated, takes time, and it is not possible to check whether the blowing direction is appropriate (whether the target portion is located inside the high cleanliness space).

  Of course, this problem does not occur if the air outlet can be arranged in the immediate position of the target part, but various surgical or treatment devices are often arranged in the immediate position of the target part. In addition, since a space for surgery or treatment is required, the air outlet must be arranged at a position somewhat away from the target portion. And the adjustment work of a blowing direction becomes difficult in proportion to the separation distance from a target part.

  In addition, once the adjustment work is completed, during the operation or treatment, the blowing direction is changed against the user's intention due to external force or the like, and the target part may be removed from the high cleanliness space. In this case, since the boundary of the high cleanliness space cannot be visually recognized, there is a problem that the operation or treatment is continued without grasping the fact.

  Furthermore, when the installation position of the air outlet cannot be secured within a sufficiently close range from the target part (when it must be installed at a position away from it), a high cleanliness space is formed near the target part. In this case, there is a problem that it is impossible to confirm whether or not the target portion is located inside the high cleanliness space because the boundary cannot be visually recognized.

  The present invention is intended to solve the above-described problems in the prior art. The range of the high cleanliness space can be visually confirmed, the clean air blowing direction can be easily adjusted, and the blowing direction can be adjusted. An object of the present invention is to provide a local type clean air supply device that can easily check the suitability.

The clean air supply unit is connected to the power supply unit. Built-in fan driven by supplied drive power, pre-filter and main filter, the sucked air passes through the pre-filter and main filter and is purified, then blows forward from the air outlet Of the clean air supply unit configured to be able to freely adjust the height position, the swinging angle in the left-right direction, and the whirling angle, and to be supplied with clean air from the air outlet It has a sighting means for visualizing the range high cleanliness is ensured in front of the space, aiming means, the plurality of laser light emitting portions, each for outputting a laser beam toward the front of the air outlet Configured it, is characterized in that the laser beam is output so as to surround the range of high cleanliness is ensured in front of the space of the clean air supply unit.

  In addition, it is preferable that the clean air supply unit is supported by a support column or the like via an articulated arm having a plurality of hinges so that the three-dimensional position can be freely adjusted.

  The aiming means is configured to output each laser beam through a position at a predetermined distance from the center line in parallel with the center line of the flow of clean air blown from the air outlet. It is preferable.

  It is preferable that an acceleration sensor is built in the housing of the clean air supply unit, and when the three-dimensional position of the clean air supply unit, the swing angle in the left-right direction, or the rolling angle is changed, This is preferably detected by an acceleration sensor, and thereafter, a laser beam, a spot laser beam, or a spot beam is automatically output over a certain period of time.

  In addition, a distance measuring unit is arranged in the clean air supply unit, and the distance from the clean air supply unit to the target portion is automatically measured. When the distance value exceeds a certain value, the distance measuring unit visually For the range to be converted, it is preferable to be configured to warn that high cleanliness cannot be guaranteed.

  Further, the separation distance threshold for determining whether or not to issue a warning is configured to be automatically set to an appropriate value according to the set air volume of the clean air blown from the air outlet. preferable.

  The local type clean air supply apparatus according to the present invention can visualize the range of the high cleanliness space formed in front of the clean air supply unit by the clean air supplied from the air outlet by the aiming means, Since the boundary between the high cleanliness space and the other spaces can be easily visually recognized, it is possible to easily adjust the blowing direction of the clean air and to check whether the blowing direction is appropriate.

  Also, an acceleration sensor is built in the housing of the clean air supply unit, and this is detected when the three-dimensional position of the clean air supply unit is changed, and then a laser beam or the like is output over a certain period of time. In such a case, in the event that the blowing direction is changed against the user's intention during use, the user can be immediately notified of this, and the target part Can be readjusted immediately if it is out of the high cleanliness space.

  In addition, when the distance measuring means is arranged in the clean air supply unit so as to warn that the distance is too far from the target part, a separation distance (from the target part to the air outlet) that ensures high cleanliness is ensured. Can be confirmed, and the problem that surgery or treatment is performed at a position deviating from the high cleanliness space can be preferably avoided.

FIG. 1 is a perspective view of a local clean air supply device 1 according to a first embodiment of the present invention. FIG. 2 is a side view of the local clean air supply device 1 according to the second embodiment of the present invention.

  Embodiments (first embodiment and second embodiment) of the “local clean air supply device” of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a local clean air supply device 1 according to a first embodiment of the present invention. As shown in the figure, the local clean air supply device 1 basically includes a base 2, a power supply unit 3 placed on the base 2, a control unit 4, and an upper part of the control unit 4. And the clean air supply unit 5 supported in the above.

  A caster 2a is attached to the lower end of the base 2 so that the entire apparatus can be easily moved, and it can also be prevented from moving easily by operating a stopper attached to the caster 2a. .

  The power supply unit 3 supplies power to the control unit 4 and the clean air supply unit 5, and is equipped with a power cord for AC 100V (not shown) and a battery. It can be used with a power cord connected to a commercial power outlet, or it can be used without being connected to a power outlet by charging the battery in advance.

  The clean air supply unit 5 incorporates a fan that is driven by driving power supplied from the power supply unit 3, a pre-filter configured by a nonwoven fabric, and a main filter configured by a HEPA filter. When the fan is driven, air is sucked from an air suction port (not shown) formed on the back side, and the air flowing into the interior passes through the pre-filter and the main filter and is then purified. The air is blown forward from the air outlet 5a formed on the front side.

  The clean air supply unit 5 is attached to the upper end of the up and down support column 6 so as to be rotatable about the vertical axis V and the horizontal axis H, and to the power supply unit 3 and the control unit 4. In addition to adjusting the height position by moving the clean air supply unit 5 in the vertical direction, the swinging angle in the horizontal direction and the whirling angle can be adjusted freely, whereby clean air from the air outlet 5a The supply direction can be set freely.

  Aiming means (laser light emitting unit 7) is disposed on the front surface of the clean air supply unit 5 (around or inside the air outlet 5a). This aiming means is a range of a high cleanliness space formed in front of the clean air supply unit 5 by clean air supplied from the air outlet 5a (more specifically, a range in which the cleanliness of class 100 is guaranteed. ) To visualize.

  In the present embodiment, the aiming means is constituted by four laser light emitting units 7 (7a to 7d). More specifically, as shown in FIG. 1, the laser light emitting units 7 a to 7 d are front surfaces of the clean air supply unit 5, one on each of the upper side, the lower side, and the left and right sides of the air outlet 5 a. The laser light emitting units 7a and 7b output horizontal laser beams (horizontal reference lines L1 and L2) toward the front of the air outlet 5a, respectively, and the laser light emitting units 7c and 7d are vertically Laser beams (vertical reference lines L3 and L4) are output, respectively.

  These laser beams (reference lines L1 to L4) pass through a position at a predetermined distance from the center line D in parallel with the center line D of the flow of clean air blown from the air outlet 5a. It is output so as to surround the high cleanliness space of class 100 formed in front of the clean air supply unit 5 by the clean air supplied from the air outlet 5a.

  Therefore, when this local type clean air supply apparatus 1 is installed in an operating room and a patient is operated on, a local space centered on the affected area of the patient is to be maintained with high cleanliness. So that the affected area of the patient is surrounded by the laser beams (reference lines L1 to L4) output from the laser emission sections 7a to 7d, the height position of the clean air supply section 5, the swing angle in the left-right direction, and What is necessary is just to adjust a rolling angle.

  In the present embodiment, an acceleration sensor is built in the housing of the clean air supply unit 5, and the height position, the swing angle in the left-right direction, or the rolling angle of the clean air supply unit 5 is set. When the change is made, this is detected by the acceleration sensor, and thereafter, laser light is automatically output from the laser light emitting units 7a to 7d for a certain time (for example, 5 seconds). Accordingly, when positioning (adjustment of the height or direction of the clean air supply unit 5, that is, adjustment of the clean air blowing direction), the laser beam is output by moving the clean air supply unit 5 a little. The height or direction of the clean air supply unit 5 may be adjusted while referring to the reference lines L1 to L4 irradiated to the target part (patient affected part or the like) or its peripheral part.

  Further, even when the local type clean air supply device 1 is moved by an external force against the user's intention or when the direction of the clean air supply unit 5 is changed, the acceleration is also applied. A laser beam is automatically output from the laser emission units 7a to 7d in response to the sensor, and the high cleanliness range of class 100 formed by the clean air blown out from the clean air supply unit 5 is the target portion. It can be easily confirmed whether or not the patient has been removed from the affected area.

  In addition, the output of the laser beam from the laser light emission parts 7a-7d can also be manually performed by operating the operation panel 4a of the control part 4. FIG.

  FIG. 2 is a side view of the local clean air supply device 1 according to the second embodiment of the present invention. In the present embodiment, the clean air supply unit 5 is supported on the upper end of the column 6 via an articulated arm 8 having a plurality of hinges 8a. From the position shown in FIG. In addition to being able to freely move in the direction and the front-rear direction, the three-dimensional position of the clean air supply unit 5 can be freely adjusted within the movable range of the articulated arm 8, and the swing angle in the horizontal direction, and The whirling angle can be freely adjusted, whereby the supply direction of clean air from the air outlet 5a can be freely set. Therefore, for example, as shown in FIG. 2, it can be arranged above the operating table 10 at a position that does not interfere with various surgical or treatment devices.

  The local type clean air supply apparatus 1 of the present embodiment is different from the first embodiment only in that the clean air supply unit 5 is supported via the multi-joint arm 8, and the other configurations are almost the same. This is consistent with the first embodiment. That is, a caster 2a with a stopper is attached to the lower end of the base 2, and a power supply unit (in this embodiment, the power supply unit is housed in the control box 9 together with the control unit). In addition to the power cord attached, the battery is mounted, and the clean air supply unit 5 has a fan, a pre-filter (nonwoven fabric), and a main filter (HEPA filter), and is formed on the front side. Clean air is blown forward from the air outlet 5a.

  Further, the clean air supply unit 5 has an acceleration sensor built therein, and further, a front surface of the clean air supply unit 5 is formed in front of the clean air supply unit 5 by the clean air supplied from the air outlet 5a. Aiming means (laser light emitting units 7a to 7d) for visualizing the range of 100 high cleanliness spaces are arranged.

  In the first embodiment and the second embodiment, as an aiming means, toward the front of the air outlet 5a so as to surround a high cleanliness space of class 100 formed in front of the clean air supply unit 5. Laser emitting units 7a to 7d that output horizontal reference lines L1 and L2 and vertical reference lines L3 and L4 are used, but the laser emitting unit is arranged at the center position of the air outlet 5a, and the air outlet 5a. The spot laser beam may be output so as to coincide with the center line D of the flow of clean air blown out from the LED, and the spot beam is not emitted from the laser beam but from the LED (or other light source). You may comprise so that it may be output.

  In this case, the height position (or three-dimensional position) of the clean air supply unit 5 and the swinging in the left-right direction are performed so that the output spot laser beam or spot beam hits the center of the target part (patient affected area) Position adjustment (adjustment of the blowing direction of clean air) may be performed by adjusting the angle, the whirling angle, and the like.

  Furthermore, a distance measuring means (laser distance meter, etc.) is arranged on the front surface of the clean air supply unit 5 to automatically measure the distance (separation distance) from the clean air supply unit 5 to the target part, and to determine the value of the separation distance Is too large (when the clean air supply unit 5 is too far from the target part), a warning is given that the cleanliness of class 100 cannot be guaranteed for the range visualized by the aiming means (for example, a buzzer sound). And a warning lamp may be turned on or blinked.

  In addition, the separation distance (distance from the clean air supply part 5 to a target part) in which the cleanliness of the class 100 is guaranteed varies depending on the amount of clean air blown from the air outlet 5a. More specifically, if the air volume is large, the high cleanliness space is formed to a position farther away, and if the airflow is small, the high cleanliness space is limited to a closer position. Therefore, in the case where the warning is issued by the measurement value by the distance measuring means, the separation distance threshold for determining whether or not to issue the warning is the set air volume of the clean air blown out from the air outlet 5a. It is preferable to configure so that it is automatically set in response.
