Desenvolvimento e validação de um sistema de monitoração de leitos hospitalares

Abstract

The health care system began to be developed from the 90's, with the aim of gathering information of beds in a common point. Developed by manufacturers of patient monitors, health care system have evolved over the years, bringing more and more tools for monitoring of patients and help health professionals. Against these objectives this thesis is to develop, along with Toth technology company located in Technology Park PUCRS, a medical device company Lifemed and with the support of the Microgravity Laboratory, a world reference in the field of aerospace physiology, a cental station system. This thesis has developed a platform for remote monitoring interface with paitent monitors of Lifemed company , able to manage and centralize physiological information from patients monitored. For the development of the central station, were created two software able to organize, manage and view information from all the monitors connected to the system. Both software were developed in C++, a programming language that combines both the necessary structure for visual applications with the needs of low-level interaction for real-time systems. The communication protocol TCP / IP, one of the strongest communication systems used in Ethernet applications, was chosen for the communication between the system and monitors. Performance tests were designed to evaluate the data integrity, system stability and reliability of data displayed. The developed system has the ability to manage up to 50 monitors Lifetouch-10 from the TCP / IP and store 96 hours of physiological data of each patient monitored. Each platform is able to simultaneously display 12 physiological waveforms and 8 parameters from up to 32 monitors in real-time, providing pre-configured technical and physiological alarms and multi speed waveform visualization. It is believed that with the implementation of remote monitoring systems in hospital environments factors such as patient mortality is reduced, improving treatment and care of hospitalized patients.
