(Week 1 - Week 3/FYP II) Pulse Sensor

As salam..
After a few months I'm getting back to update my progress
of my final project.For the semester break, I had done the
research of circuits that is match for my project. The circuits
are included for measuring :
(a) Body temperature
(b) Heart Rate
(c) SpO2

After discussed with Sir Zul (supervisor), the body temperature
is not important in this project. So, I've just focus for the
other two parameters, heart rate and SpO2. For the heart rate,
I had make an order for the 5V pulse sensor.
Badly, the sensor was not in stock in Malaysia.
So, I need to make an order from  www.pulsesensor.com

The time to be arrived is about two weeks.
When I received the sensor, straightly I'm tried the sensor by
running the program of arduino and processing.
For the early few times in testing, the waveform that should be
produce in processing was not displayed any results.
The heart beat was stick with 0 bpm.
But the sensor still gave a result by blinking the red led when
we touch the sensor without run the program. Which means the
sensor is sensed and well-functioned.

Then, I met Sir Zul by showing him the sensor and informed him
what was the matter that I faced. So, what he was done, he just
edit the serial port by looking on the COM No.
Which is means, the serial port had displayed 3 ports :
COM3, COM6 and COM11.

The COM was running in arduino is COM11.
In processing the COM11[2] should be written in the program.
If let say the serial port is COM6,
it should be written COM6[1].
So, the problem is solved by edit the serial port.
The result is displayed as required.
Unfortunately, the picture of the result was not taken.

I was said that because after it was success, when I want to
try it back for the next few days, the sensor was back by not
gave any result.When I connected to the A0, the LED not blink.
When I touched the sensor the LED still not blink.
It means that no sense detected.
When I'm running the program for arduino and processing,
the result not showed as required.
I'm trying so many times, and the result still the same.
So, what can I do is construct the circuit that suitable for measuring the
heart rate.

The sensor that will be used is LDR and Red LED.
The IC will be used LM358 or LM741.
The explanation about the IC will be update in the next post.
Below is shown how is the pulse sensor was looked.

The packaging of  5V Pulse Sensor

The pulse is applied to the finger and the Red LED is blinked at that time

The flow of the project

As shown in the previous post, that is how actually

remote patient monitoring system is working out.

After had the discussion with my supervisor,

I've decided to change the flow of the project.

Actually, the project is takes time to complete.

It might take about 2 years to finish the project.

The flow of the project is also quite complicated.

That is because there are a lot of parts that relate

with the telecommunication system.

So, the application of PDA then link to the web 

server and the data is directly accepted by the clinician
through their own gadget (laptop) are changed.

It will be changed with this flow that shown below :

The system of Remote Patient Monitoring System by using the iOBridge

Block Diagram of Remote Patient Monitoring System

From the block diagram is shown at above, the sensor
is consists of the measurement blood pressure, heart
rate and the oxygenated in blood (SpO2). Then, the
measuring data will convert to digital through the ADC.
This parts are acts as the input. The data will transmit to
the clinician's gadget (hand phone, laptop and PDA) that
acts as the output, by passing through the Internet
Enabled Microcontroller also known as the processor.
The microcontroller that chosen from the reseacrh is
iOBridge-204.

Next post will explain how the progress of the project. :)

What is the Remote Patient Monitoring ??

~  Remote Patient Monitoring is a system that will monitor

   patients at their bed or home by clinician through the    

   remote location at the hospital.

~  Architecture of the system : 

Figure 1 

   

  (a) In Figure 1, the basic of model in generally : 

      i - Medical Sensor Module will be attached to 

          the patient to record the patient's data.

     ii - The data will be forward to the PDA through

          a wired channel (USB or serial port).        

              

* The PDA will contain an application for local monitoring

  of patient's data that would display the current readings.

     

    iii - The PDA will connect to a remote server and transfer 

          the data to it.

    iv - The remote server will process the data, the Clinical

          Decision Support System to perform analysis data. 

     v - The Electronic Medical Record service to record the

         readings in the patient's history and provide feedback

         to the PDA screen notifying the decision given by the

         Clinician Decision Support System.

~  The web server also handle requests from the clinician's

   terminal and provide reports about the patient's situation.

~  An electronic medical record system will be used to store 

   the incoming data to the patient's record. 

~  The clinical decision support system will provide automated 

   analysis of data and assist the clinician in decision making 

   process.

How is the Remote Patient Monitoring works ??

This video might be help to understand how the Remote Patient Monitoring is applied.. :)

This one is the video of the Remote Patient Monitoring that is applied in Pakistan

Looking for the title and an advisor.. :)

Week 1 :

~  In progress doing my research about the project title.

~  Looking an advisor for my project. 

       

Sir Zulkifli Bin Mahmoodin is the one of lecturer that I met and 

by chance he still available for being the advisor. 

Before he confirmed to be the advisor, he want me 

to list a few titles from my research and showed to him in Week 2.   

Week 2 :

~ Met Sir Zul to show my project title list :

     (a) Remote Patient Monitoring System

     (b) Electronic Stethoscope

     (c) Pulse Rate Monitor & Alarm

~ He agreed with the first one which is 'Remote Patient Monitoring System '.

In my research this project is in application of wireless. Sir

suggested to change it to make a server such as PDA.

So, that I have to make some research and find some 

journals about this project. 

p/s : Will be continued with the introduction of my project.. :)
