WIRELESS PATIENT MONITORING SYSTEM TO MEASURE HEARTBEAT, BODY TEMPERATURE AND RESPIRATION
ABSTRACT
Recently the health care sensors are playing a vital role in hospitality.
The patient monitoring systems is one of the major improvement in the hospitality because of its advanced technology.
A wireless patient monitoring system to measure heartbeat, body temperature and respiration by using embedded technology.
INTRODUCTION
In general, a compact sensor, is used to monitor the heartbeat in analog form and to check the condition of the patient we required some more components such as thermometer and respiration.
So we are here, just connected the temperature sensor and heartbeat sensor so that simultaneously we can monitor the patient’s condition.
An embedded technology is used instead of dsp technology to develop this system so that it is easy to operate and available at an affordable cost.
EXISTING SYSTEM
There are some systems present in the market but all are having some difficulties
Compact sensor
Digital Heartbeat monitor
MAIN OBJECTIVE
To overcome the disadvantages of previous systems
The specialist staying at a distance can monitor the patient condition so that he can save the life of the patient.
This system is to be available at reasonable prices.
Embedded technology is to be use so that we can monitor the patient condition easily.
PROPOSED METHOD
An advanced technique “WIRELESS PATIENT MONITORING SYSTEM FOR HEARTBEAT ,BODY TEMPERATURE AND RESPIRATION” is used.
There are mainly two parts of the system one is transmitter and the other one is receiver.
The transmitter is placed near the patient and the receiver is with the specialist doctor. So when there is any abnormality in the patient’s condition then he can monitor the situation.

MODULES
An Embedded technology is used here.
Atmel (AT89C51) is used in this system.
RF technology is used to transmit and receive the data.
To operate more easily we are using this type of microcontroller instead of dsp technology.
To reduce the complexity
BLOCK DIAGRAM OF THE SYSTEM
The signal is transmitted by using the equation
HEART BEAT MONITORING
It is very important that the heartbeat is to be normal. That is 72 BPM.
If there is any abnormality, then the patient is in the trouble.
Here we have two types to monitor the heartbeat
TYPES OF HEARTBEAT MONITORING
ECG
PULSE
ELECTRO CARDIO GRAM
The Electrodes are conned to the patient’s body
The electrical activity is generated based on that the specialist can treat.
PULSE
The heart beat is measured when the blood passes from the heart to the other parts of the limbs once per beat.
The physician looks for the pulse on the wrist of the patient
TEMPERATURE SENSOR
We can measure the temperature by using two types of sensors
Thermistors
Resistance thermometers.
DESIGN OF A MICROCONTROLLER
The microprocessor design accomplishes a very flexible
The Microcontroller that is used in this system is
AT89C51 manufactured by Atmel, MC, USA.
Full Duplex UART
8 Bit CPU optimized for control applications
The Microcontroller provides internal 256 bytes of RAM. Theses 256 bytes of internal RAM.
Input/Output port
Four I/O ports are available in AT89C51.
Each are with 8 bits only
These ports can be operated individually.
Comparision
ADVANTAGES OF PROPOSED METHOD
The staying of specialist is eliminated.
It is a multipurpose so that overall conditions are easily measured.
Easy to operate.
Compare with compact sensor it gives better performance.
CONCLUSION
Modern technologies have developed that promotes comfortable and better life which is disease free.
PREVENTION IS BETTER THAN CURE
This system is intelligent than previous systems.
FUTURE SCOPE
Multiple parameters like Blood pressure, retinal size, age and weight can be included as controlling parameters in the future.
This system also developed by using Bluetooth technology in future.
INTERFACE TO THE COMPUTER
EXPERIMENT RESULTS
On different conditions
