Patient Monitoring System through Internet is system used to track off the patient’s health statue. For example some this system will inform the doctor with patient’s heart’s pumping rate, blood’s pressure rate, and many other necessary things. Each activity in the body have different signal in this system so the doctor can differentiate each activity for what it belongs for. For instance if the activity was for brain’s signals it will be (ECG), for the heart (EEG), and for muscles (EMG). These signals called biological signals and made as a form of electrical signals. Bioelectrical signals show various biological activities.
This system needs electrodes to extract signals from the body. This system works by attaching devices on special places on the patient body and each part in the body represents a special kind of signals. This system has several parts and one of these parts is Isolation Amplifier. Isolation Amplifier is made to transfer signals to system but also it’s a main reason for patient’s safety because it prevents signals from going back. Imagine that these amplifiers don’t prevent signals from going back. What would happen? Simply the system will cause the patient and electric shock.
The second part is called Bio-potential amplifier, which it acts on bioelectric signals. Signal from patient is gone to increase level of signal by the bio-potential amplifier. All the amplifiers are made to recommend the mistakes in this system, and make sure of the electrical safety of the patient.
Data Acquisition system is the third part that transfer analogue signals into digital signals. 001010111
Analogue signals
Digital signals
Data Acquisition is responsible for : * Picking signals * Insuring safety * Increasing level of safety * Convert equivalent digital format * Saves folder on PC * Works as a server which will broadcast on other PC
Location depends on where the signal will be powerful .
Electrodes reach system 1, system 2, system 3, pc 1 then pc 2
