O.T Concept
Modular Operating Theatre provides you with all of the benefits associated with Modular onstruction with absolutely no compromise to quality or layout. We can provide much safer working environments when compared with traditional construction methods. Owing to the offsite element of modular construction there is far less disruption and noise to the surrounding area. With the Modular Building System, the hospital can experience none of the compromises normally associated with Modular construction such as “bouncy floors” and unsightly columns.

Our modular system is highly customizable ensuring the end user has no restrictions regarding layout, internal appearance and external treatments. The AHU of each OT should be dedicated and should not be linked to air conditioning of any other area. During the non functional hours AHU blower will be operational round the clock (may be without temperature control). VFD devices may be used to conserve energy Window & split A/c should not be used in any type of OT because they are purely re-circulating units and have convenient pockets for microbial growth which cannot be sealed. The flooring, walls and ceiling should be non porous, smooth, seamless without corners and should be easily cleanable repeatedly. The material should be chosen accordingly.

Clean Rooms in Hospital Theatres

Air borne contamination is mainly derived from the personnel within the operation theatre area and due to their activities. The bacterial count in operation theatre is influenced by the number of individuals present, ventilation and air flow. Studies in a number of operation theatres have suggested that there is a general relationship between total air count and risk of infection.

Proper design and ventilation of operation theatres is the most important means of controlling air borne contamination and thus preventing air borne infection in operation theatre. The operation theatre should be segregated into zones: aseptic, clean, less clean and have mechanical ventilation.
Clean Rooms

Airtech approaches each cleanroom design with a straightforward yet proven method in cleanroom principles. Whether you already have a preliminary drawing or need complete clean room design services, we can provide you with a cost effective system that meets your needs. All modular cleanrooms are designed in accordance with the appropriate clean room standard ISO 14644-1 / US Fed Std 209 as part of the overall clean room design service. Modular prefabricated clean rooms are factory engineered and designed to meet all your specifications for temperature, humidity, differential pressure, lighting, and noise levels. Our proprietary wall system can be designed and engineered to accommodate roof loads for storage or mechanical and process equipment.

We offer four type of Clean rooms:
- Hardwall Cleanroom
- Softwall Cleanroom
- Modular Cleanroom
- IVF Workshop
O.T Laminar Air Flow

Laminar flow ventilation is used in modern orthopaedic operating theatres to reduce the number of infective organisms present in the air, which may lead to post-operative wound infection. This is of particular significance in jointprosthesis surgery, where delayed and deep-seated post-operative infection may result in poor patient outcomes and substantial costs, both to patients and health care providers. To be most effective, key operating theatre staff should wear body exhaust suits whilst working in the ultraclean environment.

Laminar flow ventilation was first pioneered by Charnley in the 1960s and 1970s and resulted in a marked reduction in post-operative wound infection. As it was introduced in conjunction with other strategies to reduce sepsis, itwas not until the results of trials conducted in the 1980s by Lidwell became available, that laminar flow ventilation became widely adopted in orthopaedic operating theatres. Studies were confined to total hip or knee surgery and results demonstrated that the lower the count of airborne bacteria, the lower the sepsis rate. Much of the more recent literature is predicated on Lidwell’s findings, examining the different types of laminar flow ventilation available, the role of prophylactic antibiotics and the effectiveness of body exhaust suits. A relatively small amount of work has been published on the relationship between the number of airborne bacteria and the post-operative wound infection rate. Two recent studies, involving the move from existing older conventional theatres to modern ultraclean facilities have indicated that the role of laminar flow ventilation in the context of the use of modern prophylactic antibiotics may be marginal. In Australia, no current standards or guidelines indicate that laminar flow ventilation must be adopted in any operating theatres, however in instances where laminar flow ventilation is installed, standards prescribe the operation and testing of such ventilation.
