Saline Infusion Pump Monitoring & Alarm System (SIPMAS)

动脉内导管被用来向患者体内注入液体，如药物，或从患者身上采集血液样本。导管本身是一个带有连接器的小塑料管。将塑料管插入动脉，连接器位于患者身体外部，使注入液体或直接采集样本变得简单而无痛。动脉内插管程序在现代医疗实践中已变得非常常见，对患者有很大好处，原因有很多，特别是在大脑和心脏等关键区域进行手术时。然而，它们也不是没有风险。一个潜在的问题是，动脉内塑料管的末端可能会形成血栓，这些可能会导致轻微和重大的临床事件。为了防止血栓的形成，生理盐水被手动或通过电子输液泵滴入导管。然而，后者存在一些有据可查的缺陷，这意味着血栓形成的可能性并未被消除。这项研究旨在量化血液凝块形成事件的发生率和其他相关问题，并探索设计和开发一种新系统的可能性，该系统将在英国制造，与现有的输液泵相连，以消除这些缺陷。

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.
