Non-Injectable Connector for Arterial Systems


A Non-Injectable Connector for ArterialSystems which increases the safety of patients undergoing blood sampling was invented by two Consultants, Dr JosephCarter and Dr Peter Young, from The Queen Elizabeth Hospital King’s Lynn NHS Foundation Trust.

The potential problems associated with conventional arterial lines were the subject of a Rapid Response Report from the NHS National Patient Safety Agency in July 2008. Current arterial line systems do not prevent intra-arterial injection of drugs and this has been a reported complication which can result in dramatic consequences such as: skin loss, tissue necrosis, loss ofa limb or potentially loss of life.

In a survey of clinicians, 95% said that they would recommend the use of the non-injectable connector. It is estimated that around one million non-injectable connectors could be used in the UK annually and at least five million per year throughout the USA.

Health Enterprise East helped by protecting the idea with a patent, funded proof of concept development and supported clinical evaluation at QEH. HEE also identified a suitable commercial partner - AmDel Medical Limited.

Background

The Non-injectable Connector (NIC) is a novel device which increases the safety of patients undergoing blood sampling, invented by two Consultants from The Queen Elizabeth Hospital King’s Lynn NHS Foundation Trust (QEH), has now gone into commercial production.

The NIC has a unique design which incorporates a one-way valve, so that it only allows removal of the blood and prevents anything from being injected into the arterial line. It also stops blood from leaking out of the system should the three-way tap be accidentally left open.

Intra-arterial cannulae and monitoring systems are frequently used to facilitate beat-to-beat monitoring of blood pressure and to allow blood sampling.

The device contains an unique valve mechanism which allows blood sampling but prevents anything else being injected into the arterial line.

The design prevents blood from leaking out of the system should the three-way be left open.

The NIC may also prevent the possibility of bacterial infection which can occur with arterial line devices and may be passed to the patient.
