Abstract:
With the increasing growth of the population in Uganda, healthcare plays a vital role in leading a
contented life. In hospitals, ensuring patients’ safety is the most important thing. Hence,
automatic health monitoring systems are the most sought after because they give precise
information while reducing the stress of medical practitioners and the attendants of the patients
about missing certain critical data. Also, indicating when the intravenous fluid administered to
the patient falls below a critical level is a tedious process and a tougher job. Monitoring the level
of intravenous fluid level manually is a simpler job, but if not done with utmost care, it may
affect the health of the patient severely. This may lead to blood loss or back-flow of blood to the
IV tube from their veins. If the bottle gets fully drained, air enters the tube and, in turn, into the
vein, which may prove disastrous to the patient. So, automating this system might prove really
helpful. A system is designed such that if the Intravenous fluid reaches a critical level, it is
sensed by the Infrared (IR) sensor set up, and a micro servo motor quickly blocks the fluid flow.
An alarm sounds, and a message is sent to the nurses’ dashboard indicating the fluid drop and
flow rate. When this is done, the nurse can easily identify the patient and go there directly to
change the bottle rather than keep checking every patient to notice if the fluid has reached the
threshold level. This requires the use of an IR sensor placed at different levels of the bottle, a
micro servo motor connected to the tube between the bottle and the patient’s body, and the LoRa
module, the buzzer, and the LEDs.
