Polyethylene boosts medical safety

A RTP Company product story
Edited by the Engineeringtalk editorial team Jul 28, 2008

Applied Medical worked with RTP Company engineers to develop the compound for the feed set strap.

When Applied Medical Technology wanted to re-design its feed set systems to add a purple colour, it chose an RTP 700 series precoloured low density polyethylene compound from RTP Company for the feed set strap.

According to Brian Baker, Engineer at Applied Medical, "When providing nutrition to critical care patients through an enteral gastronomy device - a feeding pathway, or feed set, that is a direct portal to the stomach from outside the abdomen - it's imperative that feed set tubes be clearly marked to differentiate them from IV lines delivering medication to the bloodstream".

"The colour purple signifies that the tube is a food port, not a medication port".

Applied Medical worked with RTP Company engineers to develop the compound for the feed set strap.

"RTP company provided us with the exact purple colour in a material that matched our specific end-use requirements", said Baker.

"Because the system is used for feeding and in close contact with the skin, we needed a material that was flexible, nonbrittle and soft to the touch".

Applied Medical re-designed its feed set systems to comply with new regulations in the UK, which require the use of specific materials and the purple colour coding.
