ABSTRACT
The clothing system, Clean Air suit (CAS), was conceived for sterile and ultra-clean environments, and were initially proposed and used for orthopaedic surgery, passing to be used also in other surgical specialities. The main feature of the CAS’s is the contention of skin particles, not allowing its release to the outside, since it is a clothing system closed at the ends (sleeves, ankles, neck and head area) with cuffs. By standard definition, a CAS is a suit intended and shown to minimize contamination of the operating wound by the wearer’s skin scales carrying infective agents via the operating room air, thereby reducing the risk of wound infection. It is also important to refer that unlike the suit usually worn in the OR, the CAS is designed to reduce the operating contamination by personnel (Abreu, 2014). This kind of medical device is considered as Class I-medical
1 INTRODUCTION
Nowadays, comfort is a requirement almost mandatory, when designing protective equipment or any other user-focused product (Das and Alagirusamy, 2010). Also in controlled environments, such as OR theatres it is important to consider the comfort as an integral part of the requirements of protective clothing or Medical Device (MD), since this type of equipment is formulated just to meet the primary requirement: protection (James, 2011).
