1. WEB-BASED REAL-TIME REMOTE MONITORING FOR
PERVASIVE HEALTHCARE
The goal of healthcare architecture is to enable improved healthcare through the
intelligent use of wireless remote monitoring of patient vital signs, supplemented by rich
contextual information. One of its applications currently being deployed is the remote live
monitoring of a patient by a healthcare professional. The vital signs are monitored using a
wireless BAN based on sensors that can monitor position in space, ECG and blood oxygenation.
A design goal of ubiquitous access means that all communications are performed using recent
web technologies. Important aspects of this application include: inter-visibility between patient
and caregiver; real-time interactive medical consultation; and replay, review and annotation of
the remote consultation by the medical professional.
Existing System:
Patients who are at risk require that their health to be monitored frequently
whether they are indoors or outdoors. Doctors have to go around knowing the recovery status of
the patients which is time consumption.
Proposed system:
The system is divided into two phases. The first is the acquisition module and wireless
transmission module, second is data receiver module.. The device used in the acquisition module
is responsible for acquiring ECG, position in space, blood saturation and temperature, through
the use of specific leads attached to the patient during the session. The ADC circuit is used to
convert the sensors analog voltage into digital form then it fed to PIC microcontroller. The PIC
microcontroller gets the sensor data and transmits the data to the PC using ZigBee protocol. In
receiver side received data’s are uploaded to internet using VB.NET application.
