Background of the Invention:
This innovation relates to a patient support system created specifically for those with restricted movement or paralysis. Two main challenges that patients with these diseases frequently face are (1) keeping an eye on IV fluid levels, which can cause major health difficulties if ignored, and (2) expressing their requirements or emergencies to carers because of their limited mobility. Traditional systems frequently handle these requirements independently rather than in a cohesive, approachable manner. The goal of this idea is to use a single, integrated system to tackle both problems.

Summary of the Invention:
The 'Smart MedAssist: IoT-Enabled Saline Monitoring & Speech Aid for Paralysis Patient' invention is a multifunctional assistive device that helps patients who are paralyzed or have limited movement. It has three main features: it tracks health indicators like heart rate, allows gesture-based communication, and controls IV fluid levels.
A weight sensor built into the system monitors the amount of fluid remaining in the IV bag and alerts carer when levels fall too low. Additionally, it features a wearable glove with hand gesture-detecting sensors. An expressed message conveying basic needs, such as requesting help or drink, is played when a gesture is detected.
The technology also uses sensors to track the patient's mobility and heartbeat. It instantly sounds a warning if it notices a fall or an irregular heartbeat. A microcontroller collects all of the data, which is then shared via an IoT platform or mobile app to allow caretakers to keep an eye on the patient from a distance. For those who have difficulty speaking or moving, this integrated solution offers a more effective, dependable, and secure method of assistance.

Description of Block diagram:
The system is engineered to assist paralyzed patients by integrating health monitoring and gesture-based communication into a single device (Figure 1.). It utilizes various sensors: a load cell with an HX711 amplifier for accurate measurement of IV fluid weight and low-level detection; a heart rate sensor (SEN0203) that employs light to monitor blood flow and pulse; a DS18B20 temperature sensor for precise digital readings of body temperature; and multiple flex sensors within a glove that respond to finger movements to identify specific hand gestures. An Arduino Uno microcontroller processes these signals, analyzing the data to initiate appropriate responses. Should the IV fluid level fall below a predetermined threshold or if the patient's health deteriorates, the system dispatches SMS alerts via a GSM module (SIM900A) to inform caregivers. Simultaneously, recognized gestures can activate pre-recorded voice messages through a speaker, facilitating the patient's communication of basic needs. Outputs are displayed on an LCD screen, and data is transmitted to the cloud using an ESP8266 Wi-Fi module, enabling caregivers to monitor the patient in real time through a mobile application. This comprehensive approach guarantees ongoing monitoring, prompt alerts, enhanced patient safety, and a decrease in caregiver workload.
