Intra-arterial catheters are used to introduce fluids, such as drugs, into or take blood samplesfrom patients. The catheter itself is a small plastic tube with connectors. The plastic tube isinserted into the artery and the connectors lie on the outside of the patients’ body makingintroducing fluids or taking samples straightforward and painless.Intra-arterial catheterisation procedures have become very common in modern medicalpractice and are of great benefit to patients for a number of reasons, especially when operatingin critical areas such as the brain and the heart. However they are not without risk.One potential problem is that blood clots can form at the end of the plastic tube within theartery and these can cause minor and major clinical incidents. To prevent the clot formationsaline is dripped through the catheter either manually or through an electronic infusion pump.There are however a number of documented deficiencies with the latter which means that thepotential for clot formation is not eliminated.This study is to quantify the rates of blood clot formation incidents, and other associatedproblems and to explore the possibility of designing and developing a new system, to bemanufactured in the UK, that would connect with current infusion pumps to eliminate thedeficiencies.
