This study proposes a customized and reusable component-based design framework based on the UML modeling process for intelligent home healthcare systems. All the proposed functional components are reusable, replaceable, and extensible for the system developers to implement customized home healthcare systems for different demands of patients and caregivers on healthcare monitoring aspects. The prototype...
The development of pressure sores put patients at a high risk for developing infections and cause costly medical bills. It is important for wheelchair bound patients to constantly adjust positions in order to relieve pressure to decrease their chances of developing a pressure sore. The patient needs to adjust themselves at least every two hours in order to relieve the external pressure that is being...
Poor posture or extra stress on the spine has been shown to lead to a variety of spinal disorders including chronic back pain, and to incur numerous health costs to society. For this reason, workplace ergonomics is rapidly becoming indispensable in all major corporations. Making the individual continuously aware of poor posture may reduce out-of-posture tendencies and encourage healthy spinal habits...
Recently, a wearable body-sensor network realized continuous sleep monitoring by ExG (EEG, EMG, EOG, and ECG) extraction from a sleeper's face. At least 14 sensors were placed on the face, and were managed by a network controller for sleep monitoring. However, the system was too bulky and heavy (127x63.5χ28mnf, 210g) to wear during sleep, and consumed high power (>;100mW). Another system used a...
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...
This paper introduces a novel, open-source middleware framework for communication with medical devices and an application using the middleware named intensive care window (ICW). The middleware enables communication with intensive care unit bedside-installed medical devices over standard and proprietary communication protocol stacks. The ICW application facilitates the acquisition of vital signs and...
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...
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,...
This paper describes a mobile health monitoring system called iCare for the elderly. We use wireless body sensors and smart phones to monitor the well being of the elderly. It can offer remote monitoring for the elderly anytime anywhere and provide tailored services for each person based on their personal health condition. When detecting an emergency, the smart phone will automatically alert pre-assigned...
The left-ventricular stroke volume is an important direct indicator of the heart efficiency and perfusion of the vessels. Currently a valid measurement of the beat volume can only be implemented by invasive measurements procedures at the hospitals worldwide. Arterial catheterization is limited to intensive care unit (ICU) usage, costly and potential risky. Some available noninvasive methods yield...
Here we present the fabrication and the performance of a novel, wearable, robust, flexible and disposable micro-fluidic device which incorporates miniature optical components as a detection system, for wireless monitoring in real time mode of sweat pH during an exercise session. This micro-fluidic platform is completely non-invasive, with the great advantage of providing a continuous flow of fresh...
Governments in under developing countries face serious problems for offering quality healthcare services at reasonable cost due to rapidly graying population and patients with chronic diseases. Due to currently healthcare resources are not sufficient, many deaths without medication are produced. Thus, this increasing important issue needs to be attended. Our approach to tackle this issue is based...
By adding a wireless sensor network into a health monitoring system, I have found a method by using the combination of ZigBee and wireless LAN architecture to realize a remote medical monitoring system. The system's nodes and base stations use the short range communication standard: 802.15.4 / ZigBee standard. This system can collect various information from patients, achieving the remote medical...
The main purpose of this research work is to develop a wireless sensor network system that can continuously monitor and detect cardiovascular disease experienced in patients at remote areas. A wearable wireless sensor system (WWSS) is designed to continuously capture and transmit the ECG signals to the patient's mobile phone. The fastest alert will be issued to doctors, relatives, and hospitals, using...
Heart diseases are the serious health threats to human beings. Traditional cardiac monitoring systems are unsatisfactory to prevent the sudden death events caused by heart diseases. A pervasive cardiac monitoring system is thus developed, which can provide a real-time continuous cardiac care and arrhythmias detection service for any person at any time in any place. This paper gives a detailed description...
Breathing exercises form an essential part of the treatment for respiratory illnesses such as cystic fibrosis. Ideally these exercises should be performed on a daily basis. This paper presents an interactive system using a wearable textile sensor to monitor breathing patterns. A graphical user interface provides visual real-time feedback to patients. The aim of the system is to encourage the correct...
In this paper, the parameters to be measured non- invasively are fetal movement and uterine contractions with the help of novel MEMS based piezoelectric sensor as these may impose stress on the fetus. The recording was performed on 10 pregnant women in the age group of 26-38 weeks of gestation. The sensor shows the good results.
Context has been applied to a broad range of domains and systems ranging from location-based tourist applications to motion capture. An area relatively under-represented in the literature is health-monitoring systems. This paper considers the application of context in health monitoring and the role of translational research, a concept that relates to the translation of basic research into clinical...
Respiration rate is an important indicator of an individual's health. Existing respiration monitoring systems are usually contact based, and so the sensing device is attached to the subject's body. This creates discomfort to the patient and can interfere with normal breathing. This paper presents a vision based contactless method of monitoring respiration rate. The method involves image and signal...
The HeartCycle EU research project aims to provide disease management solutions for cardiac patients. Developed within HeartCycle, IMAGE is a wearable device capable of acquiring ECG, bioimpedance, and acceleration measurements. The acquired signals are stored in onboard memory and processed, while the results are wirelessly transmitted in real time to a base station. Base station processed data is...
