LeakTrapTM and EndoTrapTM are two devices developed by Palliare.
LeakTrapTM captures and extracts aerosol leaks from around the trocar during laparoscopic surgery. LeakTrapTM consists of disposable rings, which sit around the trocars, and which connect to a vacuum system. The rings have multiple openings, which capture the aerosol leaks, thus preventing them from becoming airborne in the operating room.

EndoTrapTM is a product designed to reduce endoscopists exposure to airborne particles generated during endoscopic procedures. EndoTrapTM consists of a T-piece with a valve and a protective sleeve and is intended to be used in conjunction with a face mask and a viral filter. EndoTrapTM is designed so that all inhaled and exhaled gases pass through the viral filter, thus protecting the operator from harmful biological contaminants.

Schlieren Imaging captures air flows and thus aerosols, using variations in the refraction of light as it passes through bodies of different densities. Invented in the 1860s, it is widely used today in fields such as ballistics and aeronautical engineering, to capture and analyse airflow around projectiles, wing-edges, etc. Recent work by PORSAV partners UCD has developed a Schlieren apparatus which is compact enough to use in a surgical setting. This offers unprecedented insights into the atmosphere of the OR, and in particular the leaks that escape into this atmosphere.
