1. design Air Shield analysis

2. The main goals of a modern O.R. are: Aseptic environment Flexibility evolution Ready to operate timing analysis Air Shield

3. Surgeon Strumentation technician Anestesist O.R. attendant Ergonomic analysis of the working areas used by the personal. Get different areas with different aseptic grades analysis Air Shield

4. How is the clean air distributed into the O.R.? analysis Turbolent distribution: generic surgery Air quality class: FED 209: class 10.000; ISO 14664: class ISO7 Air flow: 15/20 ac/h Air Shield

5. How is the clean air distributed into the O.R.? analysis Unidirectional (laminar) ceiling air distribution system: specialist surgery Air quality class: FED 209: class 100; ISO 14664: class ISO5 Air flow in the aseptic zone only: 250 ac/h Air Shield

6. analysis This seems to be the best air distribution possible, but the aseptic air flow is obstacled by a warm air layer, that come from the operating area and from the presence of operating lights. The aseptic air flow is not any more perfectly vertical but open to the extern and doesn’t reach the operating point. Air Shield

7. Which is the Air Shield solution? analysis “The ‘AirShield’ A/C system” Air flow: 210 m3/h directly on the hot-spot! Laminar air flow speed: 0,29 m/s. Final filter efficency: H13 P.C.: 250 Pa The aseptic air flow isn’t obstacled by hot air layers or from operating lights. The aseptic air flow perfectly reaches the operation point. Air Shield

8. During an operation inside the room there are two different working zones: Aseptic area Outer area Objective: create a very aseptic area as near as possible to the operating point concept Air Shield

9. This two operating areas evidence the need to get as lower as possible the air contamination into the operating rooms. project The ‘Air Shield’ A/C system performances are: Air flow: 210 m3/h directly on the hot-spot! Air flow speed: 0,29 m/s Air Shield

10. A/C unit outside the operating room Air extraction Aseptic air flow All the operating theatre can adopt The ‘Air Shield’ A/C system. They can drastically maximize the aseptic air flow on the hot-spot. This is the all surgeons need and it will be a standard procedure in the future operating rooms. The A/C system, placed outside the O.R., extracts the air from the O.R. and, after a filtering procedure, it gets the air directly on the operating point again. The Air Shield is completely free to move around the operating area.

11. Air Shield ‘Air Shield’ A/C system components are: Aseptic air distribution system (in to the operating room) A/C system (Hi-tech and very compact – Outside the operating room)

12. The ‘Air Shield’ A/C system is a new high-tech project developed by EGGS DESIGN and TECNAIR LB to achive a perfectly aimed aseptic air flow (filtered by HEPA air-filter) and get it directly above the operating field (about 31’’ above the operating area). The ‘Air Shield’ environment is plugged directly on the main source of the operating room’s aseptic A/C system. In case the operating room hasn’t an indipendent aseptic air source, it’s possible to install a new very compact A/C system near the O.R. A ceiling supply system allows the Air Shield system to be completely free of move against the wall/ceiling and the manual operated vertical adjustment, with weight compensation by means of springs, take the air flow directly on the surgical hot- spot. The ‘Air Shield’ system gets the aseptic air flow into the room through a microspotted fabric. The air flows directly on the hot-spot or on all the stuff to be kept aseptic. Optionally it is possible to install a lighting system with optical-fiber wires that supplies cold white light. FIELDS OF INTEREST The ‘Air Shield’ A/C system should be used in O.R. environments, pharmaceuticals rooms, E.R.s and all those environments where it should be granted the maximum level of aseptic air. product Air Shield
