Description

  The present invention relates to an operating room illumination device and an operating room equipped with the same.

  In general, in a hospital operating room, a bioclean operating room is employed in order to prevent air-borne bacterial infection in patients undergoing surgery. Airborne infection occurs when bacteria contained in dust from surgeons involved in surgery, or particles floating in the air to which these bacteria adhere, reach the surgical site of the patient and adhere to it. . Therefore, in the bioclean operating room, clean air that does not contain particles and bacteria in the air is blown out from the ceiling outlet of the operating room.

  As an example of such a bioclean operating room, a laminar flow unit provided on the ceiling surface, a surgical light provided below the laminar flow unit, and an operating table provided below the surgical light, A booth-type clean unit including the above has been proposed (see Patent Document 1 below). In this booth type clean unit, the purified air that has passed through a laminar flow generating plate formed of a porous punching plate provided in the laminar flow unit is supplied downward.

  The horizontal joint type LED unit 202 has the same configuration as the vertical joint type LED unit 201 except that the horizontal joint 225 is provided on the standing wall portion 214A, and thus the description thereof is omitted.

  As shown in FIGS. 2 and 4, the support frame body 130 has six hollow pipes (support frames) 131, 131... Extending radially from the support shaft 110 toward the outside in the radial direction R. These six hollow pipes 131, 131... Are arranged at equal intervals in the circumferential direction T. The ends of the hollow pipe 131 on the outer side in the radial direction R are connected to each other by an annular pipe ring 132.

  A hanging support member 133 is provided in the middle of the hollow pipe 131 in the radial direction R. In addition, an outer side support material 134 that hangs down is provided on the outer end in the radial direction R of the hollow pipe 131.

The pipe ring 132 is provided with an auxiliary handle 135 on the outer side in the radial direction R. By operating the auxiliary handle 135 together with the shaft handle 111 provided on the support shaft 110, the height and direction of the lighting device 10 can be changed.
The pipe ring 132 is provided with a variable handle 136 on the outer side in the radial direction R.

  In this embodiment, the hollow pipe 131 is an aluminum straight pipe with a diameter of 20 mm, and the pipe ring 132 is an aluminum annular pipe with a diameter of 30 mm. The hollow pipe 131 has one end fixed to the support shaft 110 by welding and the other end fixed to the pipe ring 132 by welding.

  Since the hollow pipe 131 and the pipe ring 132 are formed of pipes, the inside is hollow. This interior is a housing space 139 that can accommodate a power source line 218 (see FIG. 3) and a linear member such as a variable wire connected to the surrounding lighting body 140.

  The ambient lighting bodies 140, 140... Are respectively provided on the six hollow pipes 131, 131. In the present embodiment, the ambient lighting body 140 is connected to a rotation support member 133 that hangs down from the hollow pipe 131, and includes five horizontal joint type LED units 202 provided on a horizontal support member 160 that extends in the radial direction R. Have.

  The five horizontal joint type LED units 202 are arranged so as to be separated from each other in a plan view, for example, so as to form a substantially regular pentagon with the five horizontal joint type LED units 202 as apexes. Thus, a gap is provided between adjacent horizontal joint type LED units 202, 202.

  A variable wire (not shown, the same applies hereinafter) is connected to the end of the lateral support member 160 that supports the lateral joint type LED unit 202 inside the outer support member 134. The variable wire passes through the inside of the outer support member 134 and the pipe ring 132 and is connected to the variable handle 136. With this configuration, by operating the variable handle 136 provided in the pipe ring 132, the operating force is transmitted to the lateral joint type LED unit 202 via the variable wire. Thereby, the surrounding illumination body 140 can adjust the diameter 120-220 mm in light outline size.

  A gap 150 is formed between the support shaft 110, the central illumination body 120, the support frame body 130, and the surrounding illumination body 140. The gap 150 allows the clean air blown down from the air outlet 22 of the air cleaning device 2 to pass downward.

  Further, the support shaft 110, the central illumination body 120, and the support frame body 130 with respect to the projection area onto the horizontal plane of the portions surrounded by the outer contours of the support shaft 110, the central illumination body 120, the support frame body 130, and the surrounding illumination body 140. The ratio of the projected area on the horizontal plane of the gap 150 formed between the surrounding illumination bodies 140 (hereinafter referred to as “void ratio”) is 0.52 or more, and 0.61 in this embodiment. .

  In the operating room 1 configured as described above, when clean air is supplied from the air outlet 22 of the air cleaning device 2 provided above the lighting device 10, this clean air is Along the air flow path S, the air flows toward the outside in the radial direction R from the top to the bottom. In other parts of the lighting device 10, the clean air flows through the gap 150 from the top to the bottom. Therefore, since the flow of this clean air is reliably ensured below the lighting device 10, a negative pressure vortex region is not formed below the lighting device 10. Therefore, since contaminated air does not flow into the lower part of the illuminating device 10, it is possible to prevent airborne infection of bacteria on the operating table 5 disposed below the illuminating device 10.

  Further, since the plurality of hollow pipes 131 of the lighting device 10 are arranged at equal intervals in the circumferential direction T, the clean air flows evenly in the circumferential direction T. Therefore, the flow of clean air that flows from the center of the lighting device 10 toward the outside in the radial direction R and downward is uniformly formed in the circumferential direction T. Therefore, bacteria can be prevented from flowing toward the operating table 5 from any direction around the operating table 5 arranged below the lighting device 10.

  Further, since the LED 211 is less likely to generate heat than a general halogen lamp or the like, it is possible to suppress the generation of turbulent flow by suppressing the generation of ascending airflow compared to a lighting device including a halogen lamp. Therefore, the flow of clean air from the upper side to the lower side is reliably formed.

Further, for example, the power supply line 218 connected to the central illuminating body 120 and the surrounding illuminating body 140 is accommodated in the accommodating space 139 in the support frame body 130. Therefore, it is possible to prevent the flow of clean air from being disturbed by the exposed power supply line 218 or the like.
Further, when the power supply line 218 is inserted through a through hole formed in the vertical joint 215 and taken out from the upper end of the vertical joint 215, the power supply line 218 can be completely accommodated in the lighting device 10. The disturbance of the flow of clean air can be further prevented.

(Examples and comparative examples)
First, the relationship between the porosity and the contamination range is shown below.
As shown in FIG. 5, as an embodiment, a vertical rectification type clean room having a fan filter unit 300 provided thereon is adopted. In this vertical rectification type clean room, an air flow is set to a flow rate of 0.35 m / s, and a simulated lamp body 301 in which an aluminum plate having a diameter of 60 mm is laid in an aluminum pipe ring having a diameter of 600 mm is attached. Further, the dust generation points were point A and point B, which were 100 mm below the simulated lamp body 301 and at a distance of D mm from the simulated lamp body 302 in the horizontal direction. The point A is D = 300, and the point B is D = 100 mm. The measurement point E was 1000 mm below the simulated lamp.

  In the above simulated lamp body 301, the porosity is changed to 0%, 41%, 52, 59%, and the contamination result at the measurement point E is shown in FIG.

  According to FIG. 6, when the porosity of the simulated lamp body 301 is 0%, it can be seen that the contamination range F reaches a diameter of 1200 mm. Further, the contamination range F is not different between the case where the dust generation point is the point A and the point B.

It can also be seen that when the porosity of the simulated lamp 301 is 41% to 59%, the contamination range F gradually decreases as the porosity increases. Specifically, when the dust generation point is point A, the contamination range F is 800 × 600 mm when the porosity is 41%, and there is no contamination range F when the porosity is 52%. I understand. In addition, when the porosity is 59%, it is understood that the contamination range F is the minimum regardless of whether the dust generation point is point A or point B. That is, when the porosity is 52%, the contamination range F is remarkably smaller than the porosity of 41%. Therefore, the porosity is preferably 52% or more. In this case, it can be seen that a negative pressure vortex region is not formed below the simulated lamp body 301.
Here, in the embodiment described above, since the porosity is 61%, there is no possibility of attracting ambient contaminated air and propagating it to the center.

Next, the relationship between the lighting device and the cleanliness is shown below.
The air purifying apparatus 2 shown in FIG. 1 supplies clean air whose temperature and humidity are adjusted to about 16 times or more of the volume of the operating room 1 per hour. Further, the exhaust amount discharged from the exhaust port 16A and the exhaust amount discharged from the exhaust port 16B are substantially the same amount.

  In the air cleaning device 2, the central blowing air speed without blades was 0.47 m / s, and the blowing air speed between the guide blades 23 was 0.4 to 0.7 m / s. The blade angle is set to 74 to 86 °, and the vicinity of the surgeon's head is covered with an air flow outward from the operating table 5 so as to eliminate dust generation outward. The ventilation frequency in the operating room 1 is 16 times / h.

  The illumination device 10 is attached approximately 1200 mm above the operating table 5. Moreover, the illuminating device 10 shown by embodiment shown above is employ | adopted as an Example. As a comparative example, a circular simulated general lamp with a diameter of 600 mm is adopted.

  In the examples and comparative examples, the lighting device 10 and the simulated general lamp are installed by the following two installation methods, respectively, and the cleanliness is measured. As Example 1, the illumination device 10 is installed immediately above the measurement point X3. As Example 2, two lighting devices 10 are spaced apart by 230 mm in the horizontal direction, and are installed so as to be inclined by 20 ° from the ceiling surface so as to be inclined downward as they are separated from each other in the horizontal direction. Also. As Comparative Example 1, a simulated general lamp is installed immediately above the measurement point X3. As Comparative Example 1, two simulated general lamps are installed so as to be inclined by 20 ° from the ceiling surface so as to be separated by 230 mm in the horizontal direction and inclined downward as they are separated from each other in the horizontal direction. In Examples 1 and 2 and Comparative Examples 1 and 2, the cleanliness is measured.

  In addition, two surgeons G and one anesthesiologist H are arranged in the immediate vicinity of the operating table 5. A case where dust is generated from a dust source simulating dust from the heads of these two surgeons G and one anesthesiologist H is regarded as dust during surgery. Further, a case where dust is generated for seven persons considering dust generation from work or the like around the operating table 5 is referred to as operating table surrounding dust generation (ambient dust generation). The measurement point was set at a position 150 mm above the operating table 5. The dust generation amount is set to 400,000 particles / min · person (particle diameter is 0.5 μm or more), which is the maximum value of the dust generation amount from the clean suit wearer.

First, the result of measuring the cleanliness in ambient dusting is shown in FIG.
As shown in FIG. 7, the value of the measurement point X3 was 144 pieces / cf without the lighting fixture. Moreover, in the comparative example 1, the value of the measurement point X3 is 505 pieces / cf. That is, it can be seen that the simulated general lamp is a secondary contamination source that sucks contaminated air below the lighting device 10 and re-releases this contaminated air toward the surgical part.

  On the other hand, in Example 1, the value of the measurement point X3 was 60 / cf, which was cleaner than the case without the lighting fixture.

  In Comparative Example 2, the value of the measurement point X3 was 316 / cf, which was cleaner than Comparative Example 1. This is because the contaminated air below the simulated general lamp is diluted by the clean air blown down between the two simulated general lamps.

  On the other hand, in Example 2, the value of the measurement point X3 was 16 pieces / cf, which was the cleanest state. This is achieved by supplying clean air that has passed between the illuminating devices 10 and 10 to the surgical portion together with the illuminating device 10 passing most of the clean air downward.

Next, FIG. 8 shows the result of measuring the cleanliness in the case where dust generation during surgery occurs in addition to ambient dust generation.
As shown in FIG. 8, the value of the measurement point X3 was 116 to 144 pieces / cf without a lighting fixture. Moreover, in the comparative example 1, the value of the measurement point X3 is 1,500 pieces / cf.

  On the other hand, in Example 1, the value of the measurement point X3 was 52 / cf, which was cleaner than the case without the lighting fixture. This is because the clean air passing through the center becomes an outward flow, and it is cleaned by eliminating ambient polluted air.

  Moreover, in the comparative example 2, the value of the measurement point X3 was 839 pieces / cf, which was cleaner than the comparative example 1. This is because the contaminated air under the lamp was diluted with clean air blown down between the two simulated general lamps.

  On the other hand, in Example 2, the value of the measurement point X3 was 27 / cf, which was the cleanest state. This is achieved by supplying clean air that has passed between the illuminating devices 10 and 10 to the surgical portion together with the illuminating device 10 passing most of the clean air downward.

  As described above, in the operating room 1, even when 10 people in the room perform a work to generate a large amount of dust, in the operating room 1 according to the first and second embodiments, the operating part can be kept at a cleanliness class 1000 or less. it can.

  It should be noted that the assembly procedure shown in the above-described embodiment, or the shapes and combinations of the constituent members are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.
