Patient monitor modules have various inputs for vital function measurement. We can practice many of these measurements with some students in the laboratory of biomedical engineering. However, invasive blood pressure (IBP) measurement demonstration is impossible. This paper is dealing with design and realization of a programmable invasive blood pressure simulator. This device is able to generate programmable...
Non-invasive and continuous accurate monitoring of a patients cardiovascular system can help to assure the early detection of potential abnormalities and trigger a prompt hemodynamic assessment. Such an assessment system is possible due to current advances in optical spectroscopy and signal processing. This paper presents a novel optical sensor system which facilitates the real-time monitoring of...
Requirement for monitoring the state of the elderly in care facilities is increasing year by year and the increase in accidents involving them becomes great concern. In this paper, an ultra-wideband impulse-radio (UWB-IR) monitoring sensor is suggested which focuses on the bed status most critical to the elderly that need the assistance immediately. Employing our developed state detection algorithm...
More and more, daily stress is making place in our life. Lack of physical activity, lack of psychical and mental relaxation is lowering our resistance to the stimuli, perturbing our internal harmony and can be a cause for serious diseases. As response, our body reflects the stress as different physiological changes, which can be measured and monitored. One of the changes that appears is in Pulse Wave...
This paper presents an EKG system-on-chip (SOC) for portable health care and home monitoring applications. The EKG system acquires three channel EKG from front-end circuits and includes functions such as beat detection, interval calculation, and time-frequency analysis of heart rate variability (HRV) in real-time. An HRV analysis engine has also been developed using Lomb periodogram for time-frequency...
Our design uses a low-power laser reflection mark to detect the chest fluctuation of a patient's breath. If the breath rate is abnormal, a warning message is sent to the hospital by the embedded system.
Interactive video games are being used increasingly to transform the dull and repetitive nature of rehabilitation exercises into an enjoyable play by moving limbs or whole body. One major benefit of using video games in rehabilitation is the possibility of home-based treatments. Video games open up new options for occupation therapists to remotely supervise the compliance of patients with their rehabilitation...
We introduce BEAT (Bio-Environmental Android Tracking), which provides methods for collecting, processing, and archiving one's daily vital and spatiotemporal statistics using off-the-shelf wireless devices and biologic and environmental sensors. BEAT can operate in a self-contained manner on a mobile device and analyze vital information in real time. It uses statistics such as heartbeat variance and...
This paper presents a zero configuration HomeCare gateway which enables the remote patient monitoring. The proposed solution facilitates the automatic service discovery from ZigBee medical sensor network and also the doctor could adjust the monitoring configuration by uploading a new service profile to telemedical platform. It is believe that the proposed solution could achieve win-win situation for...
The QRS complex detection technique for intelligent ECG monitor was presented. Firstly, the pretreatment of ECG data including the rejection of 50Hz power-line interference and the removal of baseline wander was focused on. Afterwards, the method combining the differential threshold method and the amplitude detection method was introduced for localization of R-waves. The improved Tompkins differential...
Personalized requirements practices can be applied to specify goals as part of a clinical plan to aid cognitive rehabilitation. In this context, requirements monitoring can aid clinicians in tracking user behaviors as they attempt to achieve their goals. Quality metrics over stream-mined models can identify potential changes in user goal attainment, as a user learns his or her personalized emailing...
This paper describes a highly mobile collaborative patient-centric, self-monitoring, symptom recognition and self intervention system along with a complementary clinical nursing tool to aid in collaborative patient/clinician chronic cardiac disease management. Our system is composed of a mobile smart phone and wearable sensor suite linked through blue tooth and cell phone technology to a backend data...
Falls are a major cause of hospitalization and injury-related deaths among the elderly population. The detrimental effects of falls, as well as the negative impact on health services costs, have led to a great interest on fall detection systems by the health-care industry. The most promising approaches are those based on a wearable device that monitors the movements of the patient, recognizes a fall...
Wireless body sensor networks (WBSN) hold the promise to enable next-generation patient-centric mobile-cardiology systems. A WBSN-enabled electrocardiogram (ECG) monitor consists of wearable, miniaturized and wireless sensors able to measure and wirelessly report cardiac signals to a WBSN coordinator, which is responsible for reporting them to the tele-health provider. However, state-of-the-art WBSN-enabled...
Real-time monitoring of the physical condition of the patients is one of the major challenges faced by hospital authorities nowadays. All the hospitals today have one Patient Monitoring System (PMS) per patient. Also human intervention is needed frequently for critical patients. In this paper we propose a network based Wireless Single PMS (NWSPMS), which can monitor multiple patients to measure various...
This paper proposes a system that could perform real-time monitoring of complex conditions on streaming data from various body sensors within a Wireless Body Area Network (WBAN). The system enables personal medical applications to be developed using personal electronic devices combined together with sensors in a WBAN. The main techniques developed are the query language which supports windowing capabilities,...
Monitoring the impact of sleep deprivation on thermoregulation requires a careful measurement of skin temperature across the human body to have precise knowledge and understanding of the stability of circadian rhythms, the 24-hour cycles of biological activity. However, medical measurements and clinical trials are often carried out in controlled lab settings, which limits the realism and the duration...
Small-size, light-weight, flexible and programmable, yet low-cost sensor node is one of the keys to enable Wireless Sensor Network (WSN) research and a wide range of user applications. In this paper, the Bracelet computer is presented. The system is designed to be flexible and wearable that it supports a range of daughter boards of user's choice, and provides different ways for the boards to be connected...
Health-care monitoring with Wireless Sensor Networks (WSN) has become a major interest during the last few years. The use of efficient communication protocols is crucial in minimizing transmission delay and energy consumption of sensor nodes. In a heterogeneous WSN context, we propose, efficient mobility aware mechanisms which may be implemented in large three-tier WSN. These mechanisms must be designed...
Demands for better health services have resulted in the enhancement of electronic health (eHealth) systems with newer concepts such as being patient-centric, easy to use, and having smarter interactions and more accurate decisions. While eHealth services aim to provide continuous medical and health services for both consumers and medical practitioners, access to allied healthcare experts such as nurses...
