INTRODUCTION
In a corporate world people seldom find time to visit their doctors. Similarly, in a hospital where a doctor has to attend to many patients it becomes quite impossible for the doctor to monitor a patient continuously. This project provides a simple and inexpensive solution for such patients. Using this project the patients are continuously monitored using various sensors and supporting devices and the output is recorded in a PC kept in the doctor’s room. The doctor can then analyze the recorded data and if he sees an alarming sign in the recordings he can immediately reach the patient and take the appropriate action.
METHODOLOGY
The project consists of a transmitter for each of the patients and a single receiver in the doctor’s monitoring room.
The patient circuit consists of sensor unit consisting of appropriate sensors, signal processing units and a transmitter. Sensor will sense the parameter and will send the signal to the instrumentation amplifier for amplification. The amplified output is then passed through a band pass filter to filter out the unwanted frequencies. The modulator using the carrier signal generated by the carrier generator then modulates the signal. HF transmitter with help of the antenna then transmits modulated signal.
On the doctors end the receiving antenna is common for all the transmitted signals. The received signal is amplified by the pre-amplifier and the amplified signal is then filtered by band pass filter. The received signal contains information of various patients which has to be separated. This can be achieved by using narrow band receiver in conjunction with the de-multiplexer since carrier frequency for each patient’s transmitter is unique. The de-multiplexed signal is then amplified using an amplifier, detected using a detector and digitized using an ADC. Digital data is then fed to the PC via PC interfacing card. The software module written should store the data for various patients in their respective file so that the doctor can easily go through them.
APPLICATIONS
1) Transmission of signals to doctors in times of emergency.
2) Used in those hospitals where the number of specialised doctors are limited.
Brief Explanation
In our project we are monitoring the different parameters of the patient like Respiration, Temp, and Saline Bottle.
As we know that in the present scenario doctors are facing lots of problems like to monitor many patients number of doctors are required sometimes there may be shortage of doctors to monitor the patients, so in order to overcome this we have designed this project whereby we will be monitoring various parameters as explained above if anything happens in those parameters and automatically a signal will be sent to the concern person or the in charge doctor. The doctor can sit at one place and monitor all the patients at a time.
Here in our project we will be using the power line as a channel to transmit the signals which are exsisting in all most every where, no need to use any extra separate channel for this, like wireless or separate cables etc..,
