Hi Mohammed,
The medical instrumentation amplifier is a bit complicated. It needs to be isolated, to protect the pasient from lethal current and to protect itself from high voltages like defibrillation pulses. This is a datasheet for such an amplifier. Look at fig.6. **broken link removed**

Hope this helps you.
