Saline Infusion Pump Monitoring & Alarm System (SIPMAS)

动脉内导管用于将液体（如药物）引入患者体内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。塑料管插入动脉，连接件位于患者身体的外部，这使得引入液体或取样变得简单而无痛。动脉内插管手术在现代医学实践中已经变得非常普遍，并且由于许多原因对患者有很大的好处，特别是在大脑和心脏等关键部位进行手术时。然而，它们并非没有风险。一个潜在的问题是，在动脉内的塑料管末端可能会形成血栓，这可能会导致或大或小的临床事故。为了防止血栓形成，生理盐水通过人工或通过电子输液泵滴入导管。然而，后者有许多记录的缺陷，这意味着血栓形成的可能性并没有消除。这项研究是为了量化血凝块形成事件和其他相关问题的发生率，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，与当前的输液泵连接，以消除缺陷。

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.
