[Design considerations for clinical data management in an integrated remote medical system]. / Metode de management al datelor clinice intr-un sistem integrat de monitorizare la distanta.

UNLABELLED: In this paper, we present a proposal for the design of a telemedicine system. The system (called SIMPA) will be used for noninvasive monitoring of some vital parameters of patients with chronic diseases. MATERIAL AND METHODS: The telemedicine system contains a fixed unit and some mobile units. The mobile unit contains various sensors used to gather data about vital biosignals, a transceiver and a medical processor. On the fixed unit side, the host transceiver must be compatible with the mobile transceiver. On the server side, an application analyzes and processes the data and further stores it in dedicated databases. RESULTS: The database support for the telemedicine application is ensured by open source technologies and already available communication infrastructures (GSM networks). The requirements for the application were thoroughly analyzed and the Entity-Relationship diagram of the system was designed and translated into relational model. SIMPA will be implemented using only free and open source technologies, which will ensure a low cost and improved extensibility and portability. CONCLUSION: We presented some design considerations for a low-cost telemedicine system. The system will help optimize medical decisions and will increase the quality of the medical act and lower the cost, to the ultimate benefit of the patient.

[Monitoring of the SaO2 and photoplethysmography in chronic disease]. / Monitorizarea saturatiei de oxigen si a pletismogramei in bolile cronice.

UNLABELLED: Non-invasive monitoring of some vital parameters can improve the management of chronic diseases resulting an important increasing of quality of life. Today the high number of the patients, suffering of chronically diseases, put a big pressure to the health system with their demand for homecare monitoring. MATERIAL AND METHOD: In this paper are presented the design of the wearable medical device for long term monitoring of pulse wave and SaO2 using a probe that includes two light emitting diodes (LEDs), one in the visible red spectrum (660 nm) and the other in the infrared spectrum (940 nm). The device stores all the data on SD memory card for post processing. RESULTS: The monitoring device is built using an ultra low power microcontroller that offers the advantage of high integration of some circuits. The custom made electronic boards used for signal acquisition are also included modules for storage device (SD/MMC card). The pulse wave was processed in MATLAB for calculate the second derivative of photoplethysmogram as an indicator of the hardness of the blood vessel. CONCLUSION: The work was focused on design and implementation of an ultra low power wearable device able to acquire the pulse wave, causing minimal discomfort and allowing high mobility.

[Monitoring system for cardiovascular parameters of drivers]. / Sistem de monitorizare a parametrilor cardiovasculari pentru conducatori auto.

UNLABELLED: In the world the road traffic accidents are in the 3rd place at WHO cause-of-death statistics. One of the main causes of these accidents is driving fatigue as results of stress. The aim of this study is to monitoring the heart rate variability for identifying the grade of stress of the drivers. MATERIAL AND METHOD: For this stage of the study we design and build an device that recording the ECG signal and the heart rate. We analysed of line the heart rate variability for determining one possible link between the grade of fatigue and heart rate variability. The device use only two electrodes placed on the steering wheel. RESULTS: We use three categories of subjects: beginner drivers, amateur drivers with more than 3 year experience, and expert drivers. The monitoring is made for 30 minutes in intensive traffic. CONCLUSION: The preliminary results are satisfactory which determine us to continuing the research in this direction.

[Wireless device for monitoring the patients with chronic disease]. / Dispozitiv wireless pentru monitorizarea pacientilor cu afectiuni cronice.

UNLABELLED: Remote monitoring of chronic diseases can improve health outcomes and potentially lower health care costs. The high number of the patients, suffering of chronically diseases, who wish to stay at home rather then in a hospital increasing the need of homecare monitoring and have lead to a high demand of wearable medical devices. Also, extended patient monitoring during normal activity has become a very important target. MATERIAL AND METHOD: In this paper are presented the design of the wireless monitoring devices based on ultra low power circuits, high storage memory flash, bluetooth communication and the firmware for the management of the monitoring device. RESULTS: The monitoring device is built using an ultra low power microcontroller (MSP430 from Texas Instruments) that offers the advantage of high integration of some circuits. The custom made electronic boards used for biosignal acquisition are also included modules for storage device (SD/MMC card) with FAT32 file system and Bluetooth device for short-range communication used for data transmission between monitoring device and PC or PDA. CONCLUSION: The work was focused on design and implementation of an ultra low power wearable device able to acquire patient vital parameters, causing minimal discomfort and allowing high mobility. The proposed wireless device could be used as a warning system for monitoring during normal activity.

[Multi-objective optimization for fuzzy controller in neuro-muscular rehabilitation]. / Optimizare multiobiectiv a controlerelor fuzzy in recuperarea neuro-musculara.

The multi-objective optimization problem could be generally formulated as minimization of vector objectives subject to a number of constraints and bounds. Among the non-derivative problems, genetic algorithms have been proved to be a good solution in addressing ill-posed problem. We applied the multi-objective optimization to fuzzy controller design in order to obtain a optimal solution that is often a compromise between different objectives. The application that are targeted in this paper is the e-health in neuromuscular rehabilitation using electromyographies. Because our application is implemented using a micro-controller with limited capabilities, that is flash memory, computational effort, and the clock frequency, the interest is to design the smallest fuzzy architecture possible in order to accomplish the objectives. The optimal set was used in order to achieves these objectives.

[E-health application for home monitoring of neuro-muscular rehabilitation]. / Aplicatie e-health pentru monitorizarea la domiciliu a recuperarii neuro-musculare.

In many medical fields the recovery of muscular activity or its improvement up to the level of the optimal parameters is required. Apart from the classical solution for rehabilitation (physical exercises) the use of electrical stimulation has become quite frequent of late. The paper presents an interface that detects the electromyographic (EMG) activity, assesses it, and generates appropriate electrical stimuli, by means of a specific type of fuzzy control system, in order to control the dynamics of the EMG. The proposed interface will detect the motion and muscular activity, it will evaluate and generate the electrical stimulus using a fuzzy system tuned by dynamic of motion. The application will transmit e-Health information to the physician via Internet, synthetic, at request using TCP/IP stack and SMS services for wireless communication.
