場合もありうる。 In the conventional type, clean air flows down from directly above the operating table, so a sufficient cleaning effect can be obtained, but on the other hand, as shown in FIG. Since they are arranged on both sides, only the focused light rays 5 are obliquely incident on the light collecting part, and the light rays from directly above are not included, resulting in a shadowless effect. In addition, shadows may be caused by the operator or the like.

構成したものである。 The present invention provides an air purification device that is installed on the ceiling around a surgical surgical light and is configured to supply clean air in a substantially laminar flow state onto a surgical table provided below the surgical light. The air purification device includes a first air purification unit and a second air purification unit, which are provided opposite to each other with the surgical light in between, and the first air purification unit.
A third air purifying unit and a fourth air purifying unit are provided oppositely to each other with the surgical light sandwiched between them, on respective sides of the air purifying unit and the second air purifying unit. The clean air outlet of the second air purifying unit is provided so that the airflow thereof is directed toward the operating table at a predetermined angle, and the clean air outlet of the second air purifying unit is provided such that the airflow of the second air purifying unit is directed toward the operating table at a predetermined angle. The clean air outlet of the third air purifying unit and the fourth air purifying unit is provided so as to face the blowing airflow of the air purifying unit at a predetermined angle, and the blowing airflow of the third air purifying unit and the fourth air purifying unit is arranged so as to face the blowing airflow at a predetermined angle. It is provided so as to close both ends of an inverted triangular space where there is no laminar flow of clean air to be formed, and the airflows blown from the first air purification unit and the second air purification unit are merged below the surgical light. The contaminants are supplied onto the operating table in a substantially downward laminar flow state, and an air curtain is formed by the airflows blown from the third air purification unit and the fourth air purification unit to remove contaminants from the inverted triangular space.

置される。 In this embodiment, two rows of ceiling-embedded surgical lights 1 are installed in a straight line on the ceiling directly above the operating table 3, and first air purification units are installed on both sides of the surgical lights 1 in the longitudinal direction. A third air purifying unit 2' and a fourth air purifying unit 2' are respectively installed at both ends of the surgical light 1 in a direction perpendicular to the longitudinal direction. This is what I did. In this embodiment, the first air purification unit 2 and the second air purification unit 2 are the same air purification unit 2 installed symmetrically with respect to the surgical light, and the third air purification unit 2' and the fourth air purification unit 2 are installed symmetrically with respect to the operating light. The same air purifying units 2' are installed symmetrically with respect to the surgical lights. The first air purification unit 2 and the second air purification unit 2 are configured so that the laminar airflows 4 blown out from the clean air outlet 2a join together on the operating table 3 to form a laminar flow directed downward. Each of the third air purifying unit 2' and the fourth air purifying unit 2' is installed in an inwardly inclined state, and the third air purifying unit 2' and the fourth air purifying unit 2' produce a laminar air flow 4 that flows downward almost vertically from the clean air outlet 2'a. ′ is installed so that it blows out.

一として合流部分の乱流を少なくする。 Furthermore, in the air purification unit 2, the clean air outlet 2a is installed at an angle so that the air flow is merged between the surgical ceiling-mounted surgical light 1 and the operating table 3. A large amount of laminar clean air flowing out of the clean air outlets 2a of the left and right air purification units 2 merges on the operating table 3, and then continues to flow vertically toward the operating table 3. As a result, a large amount of laminar flow of clean air exists between the clean air confluence and the operating table. At this time, the air outflow speeds of the air purifying units 2 facing each other are set to be approximately the same to reduce turbulence at the merging portion.

を防止するためのエアーカーテンを形成する。 Further, the air purification unit 2' has a confluence section 6 for the clean air blown out from the air purification unit 2.
Since both ends of the inverted triangular space 7 where there is no laminar flow of clean air between the ceiling-mounted surgery lamp 1 and the ceiling-mounted surgical light 1 are closed with laminar flow, the inflow of external contaminated air in the direction of arrow 8 is prevented. form an air curtain for

とがなくなる。 Therefore, the cleanliness on the operating table 3 can be further improved. That is, when there is no laminar flow from the air purification unit 2', the air inside the inverted triangular space 7 is drawn into the laminar flow 4, resulting in a negative pressure, and the contaminated air in the operating room is sucked in the direction of the arrow 8. It mixes into the laminar flow 4. Due to the laminar flow of clean air coming out of the air purification unit 2', the space 7 is maintained in a clean room-like condition and is filled with clean air, so that the contaminated air inside the operating room is not inhaled.

とができ手術中の感染を防止することができる。 According to the present invention, the entire operating table can be placed in a clean air atmosphere, and furthermore, a downward laminar flow can always be supplied onto the operating table regardless of the direction of the surgical light, so that the entire operating table can be placed in a clean air atmosphere. The generated contaminants are quickly discharged without being lifted up, and a high level of cleanliness can be obtained without impairing the effect of the surgical light, thereby making it possible to prevent infection during surgery.
