AI Technical Summary

Technical Problem

Decubitus ulcers often develop in patients who are inactive for extended periods, as existing methods rely heavily on human schedules and experience, which can be inconsistent and ineffective.

Method used

An inflatable pressure-controlled mattress equipped with a sensor layer and air cell system that automatically detects patient inactivity by measuring pressure changes over time, alerting caregivers when necessary.

Benefits of technology

The mattress effectively monitors patient activity, reducing the risk of decubitus ulcers by providing automated alerts for inactivity, thus ensuring timely position changes and improving patient care.

Abstract

The present invention relates to an inflatable pressure controlled mattress 1 for supporting and monitoring a patient's activity while lying on the mattress 1. The mattress 1 comprises an air cell layer 7 with air cells 14a-o, which collaborate with an air source providing pressurised air to the air cells 14a-o. The air source 16 is in communication with a processor regulating amount of pressurised air to the air cells 14a-o. The mattress 1 is arranged with a sensor layer 12 arranged with a first sensor pad 17 comprising a first air conduit 18 arranged in a serpentine pattern and connected to a first sensor 19. The first sensor 19 is communicating with the processor, whereby during a pre-defined time-frequency the first sensor 19 repeatedly register pressure of air in the air conduit 18 and generates an output signal for each repeated register and communicates the output signal to the processor whereby a patient activity may be monitored.
