Abstract:
Contemporary healthcare technologies for patient monitoring and precision drug
delivery have proliferated globally, yet their elevated costs render them inaccessible
in resource-constrained settings. This research introduces a low-cost,
multifunctional IoT-enabled medical device that seamlessly integrates an automated
syringe pump with real-time monitoring of vital parameters—body temperature,
heart rate, and blood oxygen saturation (SpO)—alongside remote control
capabilities. By unifying these functions into a single platform, the device
eliminates equipment multiplicity, streamlines clinical workflows, and facilitates
efficient management during routine care and emergencies. The system leverages
a microcontroller-driven motor with a lead screw mechanism for syringe actuation,
coupled with cost-effective off-the-shelf sensors, ensuring high precision
and affordability. Rigorous validation against international standards confirmed
superior performance: the syringe pump delivered ±1.67% volumetric accuracy
and ±3.94% temporal accuracy (IEC 60601–2–24 compliant), while monitoring
achieved heart rate precision of ±1.82 bpm, SpO2 accuracy of ±0.85–0.92%, and
temperature accuracy of ±0.56–0.85°C (ISO 80601–2–61 compliant). All safety
protocols, including occlusion detection and emergency stops, demonstrated 100%
reliability. This innovation provides a scalable, accurate solution to enhance patient
safety and care accessibility in low-resource healthcare environments.
