Porvair Sciences has worked with a medical device manufacturer to develop a high-performance fluid collection vent for a surgical suction cannister using its proprietary Vyon porous plastic.
A large fraction of the waste produced during surgery is in the form of liquids such as blood and bodily fluids that have been diverted during the operation. A single surgery can produce as much as 3-4 litres of liquid waste which is often disposed of by manually pouring out the contents of the suction canisters or by solidifying the contents before disposal. Both methods can pose significant health and safety risks as spills and splatters can easily occur, leading to the aerosolisation of blood-borne pathogens.
A key component of the suction cannister is a valve found embedded in the lid which functions to maintain system integrity and prevent over spilling. This ensures the safety of both the vacuum system lines and the users by sealing off the cannister.
Working closely with the medical device manufacturer, Porvair leveraged the liquid-swelling properties of Vyon porous plastic to create a composite-based filter that could act as a vent providing both optimal airflow and an effective seal for fluids contained within the suction canister. In the novel medical device, the filter’s inherent shut-off capabilities prevent unwanted fluid transmission when collected surgical fluids reach critical levels and come into contact with the Vyon.
The Vyon fluid collection vents, used as a recyclable single use product, have been found to offer an easily installed, safe, sturdy and cost-effective alternative to traditional mechanical valves.
