Laminar Flow Enclosures

Critical surgical procedures, such as orthopaedic cases involving the implantation of prosthetic devices, demand particular attention to measures which reduce the risk of post-operative infection. A major cause of post-operative infection is airborne contamination which can be divided into two categories, via:Introduced contamination which enters the theatre via the air supply system or by other means. Internally-generated contamination due to respiration and shedding from the surgical team and their activities.FEATURESCost-effective and versatile alternatives to the construction of dedicated theatres. Provide ultra-clean air with an air change rate of approximately 500 per hour compared with no more than 20 in conventional theatres. Modular design and construction which can be installed; commissioned and tested in a new or existing operating theatre within days. Enclosures may be easily re-oriented or relocated to other theatres.OPERATIONGelman OTS Series Horizontal Laminar Flow operating theatre systems control contamination from both of these sources by means of a constant flow of ultra-clean air through a modular enclosure placed around the theatre table.Each system is composed of laminar flow modules which are self-contained filter/ fan units that recirculate air within the theatre and are independent of the theatre air supply system. All air entering the enclosure passes through a two-stage air filtration system of primary filters and final HEPA filters. The constant flow of ultra-clean air over the wound site sweeps away internally-generated contamination.When operated at the recommended airflow velocity of 0.46m/s
