The medical field is seeking a drastic change and there are many devices being introduced for monitoring the body measures like blood pressure, heart beat rate, diagnosis of heart attack symptoms and much more automatically with interdisciplinary nature. The health care system is becoming more valuable these days. In this system, the IV fluid monitoring system automatically sends a message to the nurse station through IoT technology. Our project is aimed to automatically turn off the flow of a liquid from the IV bag by using the solenoid valve. The pulse rate and the blood pressure of the patient is continuously monitored and displayed on an organic light-emitting diode (OLED). This system reduces the work of a nurse instead of keeping an eye on the IV fluid system. One of the greatest advantages of our project is the easy interface with users, the functionality of which can be managed by means of a mobile application as all the sensors are connected to the cloud using Internet of Things (IoT) technology. It can be used throughout the world.
India is placed in the 154th position in healthcare among 195 developing countries worldwide. According to the National Health Policy 2018 which aims to raise public healthcare expenditure to 2.5% of GDP from current 1.4% with more than two-thirds of those resources going towards premier healthcare. It is still the largest employment source and a significant piece of the overall socio-economic development of India. Healthcare is highly central to India’s progress. The growth of health facilities has been imbalanced India. Automation in healthcare is an emerging field unknown to us. In current era, there is no time for youngsters to concentrate on healthcare as it requires more time and work.
There are many disadvantages in the healthcare system like infection control due to assessments of doctor, heart attack due to clot of air embolism in backflow of blood in intravenous fluid, medication errors due to surgery and clinic respective. Those problems can be rectified using this system throughout the world specially in the densely populated countries, as number of patients per doctor/nurse is more and this can reduce the work to a very large extent.
Intravenous therapy is the infusion of fluid substances directly into a vein. Intravenous simply means “within vein.” IV system may be used to correct fluid imbalances, to deliver machines, for blood transfusion or as fluid replacement to correct. This way is the fastest way to deliver medicines or fluids. Therefore, it is necessary to monitor treatment through IV therapy. Our project is aimed in automating the intravenous fluid monitoring system using Arduino Uno R3. IV volume and fluid level can be precisely controlled. Also human can contact the system through IoT (Internet of Things communication protocol). Almost in all hospitals, the nurse is responsible for monitoring the IV fluid level system. But unfortunately, the nurse may forget to change or stop the drip bottle at correct time due to their schedule. This may leads to several problems for the patients. This system is able to overcome the above problem.
The user can communicate with the system through Blynk app (available on Google Play Store and App Store) as all the sensors are integrated. The IR sensor, temperature sensor, and also the heartbeat sensor will be sending the sensor outputs to Arduino Uno R3 microcontroller. After processing, the microcontroller turns off the valve if the level of the saline solution is too low. Before turning the valve off, it well send a message to the nurse station saying that the level of saline solution is decreasing.
These are the components that we are using for this project:
1. Arduino Uno R3
2. WeMos D1 Mini
3. Non-contact water level sensor
4. IR sensor
5. Temperature sensor
6. Heartbeat sensor
Almost every nurse has a smart phone with them all the time so it makes sense to use these to control automation in healthcare system. An automation system is been developed to control the electrical or mechanical appliances and the notice board digitally. Presented here is an automated device in which we can get a status of intravenous fluid system. So the nurse does not need to get up to switch off the device and they can focus on other tasks. This will ensure that the IV bag can be replaced or removed on time. Also, the pressure sensor detects air embolisms/blood clots in the catheter. The automation circuit is built using the Arduino Uno R3. In simple words, this system automatically sends a message to the nurse through IoT technology and automatically turns off the flow of a liquid from the IV system by using the solenoid valves. The pulse rate, temperature and the liquid level of the patient is continuously monitored and displayed on the OLED screen and the doctors can use the data if there is any necessity.
