It relates to the field of technologies. More specifically, the invention concerns pulmonary fluid in patients with heart failure. using bioelectrical impedance measurement to determine accumulation at an early stage a portable device and an AI-powered remote system that analyzes the data obtained from that device. It relates to the patient tracking system. 10 State of the Art In patients with heart failure, fluid retention and pulmonary congestion can worsen the disease. This is one of the most important reasons. Today, in order to evaluate the increase in pulmonary fluid... chest X-ray, lung ultrasonography, biochemical markers, and implantable thoracic Impedance sensors are used. However, a significant portion of these methods are suitable for hospital settings. It may require intervention, may be invasive, or may not be suitable for daily patient monitoring. Bioelectrical impedance measurement is a technique used to assess body fluid distribution. This is the method. However, current systems are generally devices in the form of weighing scales or multi-electrode systems. These systems are not portable or practical for daily use. Therefore, early detection of pulmonary fluid changes in patients with heart failure is crucial. There is a need for a new device that can do this, is portable, and easy to use. Purpose of the Invention The aim of this invention is to detect pulmonary fluid accumulation in heart failure patients at an early stage. A portable device that performs finger-contact bioelectrical impedance measurement to determine this. to improve. 25 The invention also enables the analysis of measurement data using AI-powered algorithms and mobile devices. The aim is to enable remote patient monitoring through the application. 2 Detailed Description of the Invention The invention involves a portable biomedical measuring device designed in card form. The device consists of the following components, as shown in Figure 1: 30 1- Finger contact electrodes 2- Electronic circuit that generates alternating current 3- Bioelectrical impedance measurement module 4- Microcontroller and Wireless communication module 5- Internal battery 35 6- Data analysis algorithm The user starts the measurement by touching two fingers to the electrodes on the device. A low level of alternating current is passed through the body via electrodes, and the resulting The bioelectrical impedance value is obtained by measuring electrical resistance. Since the electrical conductivity of body tissues varies depending on the amount of fluid they contain, 40 Measured impedance values can provide information about pulmonary fluid increase. The microcontroller inside the device processes the measured data and creates a dataset. This The data is evaluated by an AI-powered analysis algorithm to analyze pulmonary fluid. Estimates are made about its volume. The device can also connect to a mobile application thanks to its wireless communication module. Mobile 45 The patient's measurement results can be monitored through the application, and healthcare professionals can guide the patient. They can monitor it from a distance. This system is a patient monitoring tool that allows for remote monitoring of heart failure patients. It can be used as a system.
