Abstract

Objective: To design and operationally validate a low-cost automated prototype aimed at facilitating assisted postural changes in individuals with prolonged immobility and at risk of pressure ulcers. Methodology: A user-centered design approach was employed based on the ISO 9241-210:2019 standard. Semi-structured interviews were conducted with healthcare professionals to identify functional requirements, and technical testing of the pneumatic and electronic systems was performed. A functional prototype was developed, consisting of a pneumatic system integrated with an electronic system controlled via Bluetooth and programmed using Arduino. Results: The prototype enabled controlled inflation and deflation of independent sections of the mattress, allowing experimentally assisted lateral tilting. Technical testing demonstrated functional feasibility of the electronic system and stable remote control. Opportunities for improvement were identified in energy autonomy and servomotor calibration. Conclusions: The developed device demonstrates technical feasibility as an automated support system for assisted postural changes. It represents a preliminary technological solution with potential to contribute to pressure ulcer prevention strategies, though it requires further clinical validation.
