Project Development

In this final week of Fab Academy, the goal is to develop a plan for dissemination of my final project,
prepare drafts of your summary slide and video clip and put them in your root directory.

What is my project?

Hospital is injecting saline or Intravenous (IV) fluids in to the vein of patient. If the drip system is not monitored on time, it will causes problems like backflow of fluid, blood loss etc. In order to reduce the workload and overcome such critical situation in the area of an intravenous drip monitoring system, we proposed a system called Automated Intravenous Drip Monitoring System. Collapse Inefficient monitoring of IV drop leads to complications such as under Infusion, blood backflow, over infusion, air embolism Normally, doctors and nurses use their experience to estimate the time required for a drip bottle to be empty and for setting drip rate. This makes the IV infusion method to be vulnerable to human error and there are also other risks like back flow of the blood and many other if not attended when empty. IoT (Internet of Things) based monitoring and control platform for IV infusion setup which enables doctors and nurses to monitor as well as control the IV infusion setup wirelessly while keeping the cost low and making the device highly reliable

I and my family get infected with Covid 19 in last week of May.By the God grace me and my family were recovered from covid but it was too much weak and pain to site and walk after recover .So i was get worried about that my fab instructor Mr sibu support morally for this fab academy. Due to lock down and my almost all staff of my office were infected so it was also shutdown for two week. At last In month of July i planed and worked hard to complete my final project

Here is the work for project development that I had done so far:

1.Principles and Practices

In this week I had proposed my initial idea to build IoT BASED IV DRIP MONITORING

The project idea defined helped me to provide a direction to plan and complete the project.

Did it work: Yes

I defined my project idea which was useful for me

The units/segments for the system.

Photo transistor and leaser

It is used for detection of drip flow through the drip chamber.

Processor and RF module

It used for programming and Wi-Fi transmission of data to web .

LCD

It is used for the display the drip factor, drip count, weight of the IV bottle in real time

Actuator using servo

It is used for the controlling /stop the drip flow.

Load cell

It is used for measuring the initial weight of the IV bag. Also use for measuring the real-time weight

Web and mobile application

Remotely monitoring of IV bottle status.

7. Power supply

charging module and Battery

2.3D designing

In 3D designing i learnt which help me for my project 3D designing I did designing of Encloser for Board and circuit,DRIP chamber holder,actuator for servo motor holder,

After designing all the part here is the Final 3D Print

Did it work: Yes

I was using solid works tool for designing all parts

3.PCB designing

In PCB designing i has design PCB with taking reference in the WEEK-6-Electronic Design. i am using foot print of Nodemcu,Loadcell ADC and other component.

Did it work: Yes

I was using eagle tool for designing all parts

4.Input

In the WEEK-10-Input Devices I had prepared and tested for my project

week-10 input devices

Did it work: Yes

i was using Phototransiter as input

5.output

In the WEEK-12-Output Devices i had been tested and did out for my project

WEEK-12-Output Devices.html

Did it work: Yes

i was using OLED,Loadcell,LED,Buzzer as output

6.Programming

In this week I had proposed my initial idea to build IoT BASED IV DRIP MONITORING
