Saline is one of the most often utilised intravenous therapies for critically sick patients, and it has a vital role in their care. When the bottle is empty, blood will flow out of the needle and into the container. Blood will seep from the bottle if the needle is not removed. It takes a lot of time and effort to manually assess whether or not the threshold has been reached when injecting saline into a body with the usual approach. To monitor the weight of the bottle, we are using a load cell module that will send an alarm to the caretaker if the threshold value is surpassed. As soon as the caretaker notices the alarm, they will manually stop the stream. When a certain threshold is crossed, the ESP32’s servo motor pulls the regulator to stop the flow. It’s important to halt the reverse flow of blood as soon as the saline bottle is emptied. Both in the hospital and at home, this technology can be quite useful.
