Abstract

Patient specific cardiovascular system models have the potential to provide far greater insights into patient conditions than is currently possible in the intensive care unit (ICU). Access to haemodynamic data is imperative for the introduction and validation of these models for model-based care in the ICU. However, current bedside machines are proprietary systems and do not allow access to any data without potentially prohibitive cost, creating a barrier to research and advancements in bedside care. This work presents a novel, low-cost data capture system which allows real time capture of haemodynamic measurements, as well as fluid infusion rates in the ICU. The system consists of an Arduino controlled data capture unit, an adaptor for connecting to existing bedside pressure sensors, and a Python based application which displays and records data sent from the data capture system over a USB serial connection. The total system is highly customizable if needed, and costs a total of NZ$200.

一种新型临床数据采集设备：面向ICU的实时心血管建模

与目前重症监护病房（ICU）相比，患者特定的心血管系统模型有可能提供更深入了解患者状况的信息。获得血流动力学数据对于ICU中基于模型的护理的这些模型的引入和验证是必不可少的。然而，目前的床边机器是专有系统，不允许在没有潜在的高昂成本的情况下访问任何数据，这为床边护理的研究和进步创造了障碍。这项工作提出了一种新颖的，低成本的数据采集系统，可以实时采集血液动力学测量，以及ICU的液体输注速率。该系统包括一个Arduino控制的数据捕获单元，一个连接到现有床边压力传感器的适配器，以及一个基于Python的应用程序，该应用程序通过USB串行连接显示和记录从数据捕获系统发送的数据。如果需要，整个系统可以高度定制，总共花费200新西兰元。

期刊介绍： HardwareX is an open access journal established to promote free and open source designing, building and customizing of scientific infrastructure (hardware). HardwareX aims to recognize researchers for the time and effort in developing scientific infrastructure while providing end-users with sufficient information to replicate and validate the advances presented. HardwareX is open to input from all scientific, technological and medical disciplines. Scientific infrastructure will be interpreted in the broadest sense. Including hardware modifications to existing infrastructure, sensors and tools that perform measurements and other functions outside of the traditional lab setting (such as wearables, air/water quality sensors, and low cost alternatives to existing tools), and the creation of wholly new tools for either standard or novel laboratory tasks. Authors are encouraged to submit hardware developments that address all aspects of science, not only the final measurement, for example, enhancements in sample preparation and handling, user safety, and quality control. The use of distributed digital manufacturing strategies (e.g. 3-D printing) is encouraged. All designs must be submitted under an open hardware license.
