1. Bed Side Patient Monitoring System With
Automatic SMS System using GSM Technology
Aim:
This project is used to scan the complete parameters of a person in an ICU
ward.
Project Description:
Our project is a working model which incorporates sensors to measure all
these parameters like Body temperature, Respiratory Temp, Saline Status ECG
and Heart Beat rate and transfer it to the computer, so that the patient condition
can be analyzed to by doctors in any part of the hospital wherever they are. Thus it
reduces doctors work load and also gives more accurate results, wherever there is
an abnormality felt by the patient, we have also incorporated saline monitoring
system which gives an alarm when the saline bottle about to empty.
More over K-Sheet Automation is automatically done, since all the
parameters are completely monitered thro a computer, it can be stored on a
database for periodic intervals with respect to the current date and time.
A new system called medicine reminder system is also incorporated in
this project. An alarm will be energized, Whenever a particular patient should be
given medicines. This can be done for multiple patients also by assigning the
intervals for the patient to a database.

2. An Emergency patient calling switch is also included here. Whenever the
patients finds emergency he needs to press the button on his side, so that the
particular patients room number and will be indicated to the doctors room.
Modules:
Sensors and Transducers
Signal Conditioning Board
PIC Microcontroller Interface Board
Power Supply
Relay, alarm and its Driver Circuits
Advantages:
 8 independent analog channels available. (For future Enhancements)
 All the Parameters can be viewed on the Mobile phone
 Annunciation’s systems are included for all this analog inputs
 Heart Beat Rate of the Patient
 Saline status is displayed in the monitor.
 On-line graphics for selectable parameters.
 On-line recording of all process parameters in the interval selectable by the
user, which is most useful for future analysis and failure detection.
