Web based real-time remote monitoring for pervasive healthcare

  1. 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.
