Zigbee based Hospital Automation With

Online graph and WAPAim:

This project is used to scan the complete parameters of a person

in an ICU ward through Zigbee Technology

What is Zigbee:

The name "ZigBee" is derived from the erratic zigging patterns many

bees make between flowers when collecting pollen. This is evocative of

the invisible webs of connections existing in a fully wireless

environment.. ZigBee is the name of a specification for a suite of high

level communication protocols using small, low-power digital radios

based on the IEEE 802.15.4standard for wireless personal area

networks (WPANs), such as wireless headphones connecting with cell

phones via short-range radio.

The technology is intended to be simpler and cheaper than other

WPANs, such as Bluetooth. ZigBee is targeted at radio-frequency (RF)

applications which require a low data rate, long battery life, and secure

networking.

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.

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.

There is an Anesthesia injection Module Which is interfaced

with the System, can be commanded by the controller to extract the

exact amount of anesthetic fluid to the syringe.

Modules:

Sensors and Transducers

Signal Conditioning Board

PIC Microcontroller Interface Board

Power Supply

Relay, alarm and its Driver Circuits

Anesthesia Injection Module

Advantages:

8 independent analog channels available. (For future

Enhancements)

All the Parameters can be viewed on the Mobile phone

Annunciations 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.
