ABSTRACT For monitoring of physiological data of patient, we will develop a system where doctor will see the reports of ECG, EEG,EMG ,skin conductance ,respiratory signals of patients which are recorded in real time at any location . In this paper, bio-medical wireless signal recording & monitoring is easily carried out with the help of various sensor, Nexus module 10 & Bio-trace software for physiological monitoring of signals. These recorded signals would be required in training the functioning of human body. Keywords: ECG,EMG,EXG,BVP,HR,HRV

1. INTRODUCTION

Sensing of a patient‘s physiological parameters i.e blood volume pulse, ,SC ,Heart rate,RSP and transmitting them to a remote medical center is an important task of our project where expertise or medical practitioner is available. Physiological sensors here used are BVP sensor[1], Heart rate sensor, Respiratory sensor along with data actualization module i.e Nexus 10. Bio-trace Software helps to generate many reports of ECG, EEG, EMG,SC has been utilized to measure these physiological data[6]. Power consumption also considered as an important issue when we design a system for disease control.

Nexus-10 Module Nexus 10 is a portable 10 channel physiological monitoring & feedback platform that utilizes Bluetooth wireless communication & flash memory technologies. Nexus 10 offers data acquisition at a higher sampling rate i.e 2048 samples per second. The advanced technology has independent 24 bit A/D converter per channel with DC coupled amplifier allowing signals for 0 to 800 Hz including raw EEG, ECG, EMG,true DC & Slow cortical potential BVP Sensor

The blood volume pulse sensor is based on the Principle of phtoplethysmography.It emits infrared light through the tissue (skin) and measures the absorption of light by the blood flowing through the vessel. When the heart starts beating , peak in the absorption will be detected by the sensor. The pulse height defines the measure of blood flow. As the blood vessel contracts, this is called vasoconstriction also when they start expanding it is called vasodilation.The interval or distance (B)between the peaks defines the heart rate(HR) which will be expressed as a millisecond (MS) inter beat interval or as the number of beats per minute. During every heart beat, blood starts flowing through the arteries and blood vessel. At its peak, BVP signal peaks. Height of the peak indicates relative blood flow.

Skin Conductance

Sweat gland activation is a method of capturing the autonomic nerve response of human body. The activity of sweat gland in response to symathetic nerve simulation results in decrease in level of skin resistance. When human body relaxes, calm down or is peaceful, the resistance will increase and conductance will decrease.

RSP Sensor:

RSP sensor is used to record respiration rates. The movement & expansion of the abdomen or chest [5] will be done using these respiratory sensors .Its unit of measurement is breaths per minute.

Temperature Sensors:

Transducer which is used for temperature measurement in a patients monitoring system is a thermister.

EEG Sensor:

Recording of brain wave will be done using these EEG Sensor.

EMG Sensor:

EMG Sensors will be utilized in recording of the electrical activity of the muscle to determine whether the muscles are functioning proper or not. We observed that when the muscle starts contracting, the signal increases its amplitude.

Conclusion: It has been observed after experimentation, the heart rate increases during inhalation and decreases during exhalation. This effect is respiratory sinus arrhythmia (RSA), which is a representation of heart rate variability due to respiration over time. Breathing in will move the RSP signal up while breathing out will move the RSP signal down in scaling of amplitude used in our human body system. When human body relaxes and is peaceful, the resistance will increase & conductivity will decrease. It is used in Biofeedback system & will also be used to study person’s internal state & currently these equipments are used in APOLO Hospital , Delhi & in DRDO.
