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.

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.

There are some systems present in the market but all are

having some difficulties

Compact sensor

Digital Heartbeat monitor

The systems are not atomized

The patient cant able to understand the analog signals.

Complex system and difficult to operate.

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.

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.

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.

There are mainly two parts of the system one is transmitter and the other one is the receiver

In the transmitter, We have Heartbeat sensor, Respiration sensor and the temperature sensor.

All the sensors are connected to the patient The microcontroller monitors the all the system in the

transmitter if any abnormality in the patient condition then it sends the signal so that the receiver will capture the signal and will work according to that.

WORKING OF THE SYSTEM

The signal is transmitted by using the equation

The signal is received by using the equation

• 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

ECG

PULSE

The Electrodes are conned to the patient’s body

The electrical activity is generated based on that the specialist can treat.

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

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.

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.

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.

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.
