Porvair Sciences has developed a high-performance fluid collection vent for a surgical suction cannister using their Vyon porous plastic. Disposing of the waste produced during surgery can pose significant health and safety risks as spills can easily occur, leading to the aerosolisation of bloodborne pathogens. The suction cannister design has a valve embedded in the lid which maintain system integrity and prevents over spilling. This ensures the safety of both the vacuum system lines and the users by sealing off the cannister. Working closely with a medical device manufacturer, Porvair has used the liquid-swelling properties of their Vyon porous plastic to create a composite-based filter which acts as a vent providing optimal airflow and an effective seal for fluids contained within the suction canister. When the collected surgical fluids reach critical levels and come into contact with the Vyon, the filters inherent shut-off capabilities prevent unwanted fluid transmission. The company says the new Vyon fluid collection vents, used as a recyclable single use product, have been found to offer a safer, stronger and more cost-effective alternative to traditional mechanical valves.
