Electronic Alert Signal for Early Detection of Tissue Injuries in Patients: An Innovative Pressure Sensor Mattress

Area of Science:

• Biomedical Engineering
• Medical Device Technology
• Patient Monitoring Systems

Background:

• Early detection of tissue injuries is crucial for patient outcomes.
• Existing electronic alert systems lack accuracy for lightly pigmented skin.
• Surface detection of cell damage requires intact skin monitoring.

Purpose of the Study:

• To develop an innovative pressure sensor mattress for early tissue injury detection.
• To create an electronic alert system integrated with a web and mobile application.
• To enhance the accuracy of pressure sensors for lightly pigmented skin.

Main Methods:

• Developed a pressure sensor mattress incorporating body distribution, reference points, temperature, and humidity sensors.
• Integrated a web and mobile application for real-time reporting and electronic alerts.
• Calibrated sensors for specific detection thresholds: 32 mm Hg, 37 °C, 33.5% RH, 10s response time, 30g loading time, 1mA density area, and 7.05 MPa resistance.

Main Results:

• The innovative mattress effectively detects early-stage tissue injuries.
• The integrated electronic alert system provides timely notifications.
• The system demonstrates enhanced pressure, temperature, and humidity sensing capabilities.

Conclusions:

• The developed pressure sensor mattress offers a significant advancement in early tissue injury detection.
• The integrated electronic alert system improves patient monitoring accuracy, especially for lightly pigmented skin.
• This technology has the potential to reduce the incidence and severity of pressure-related tissue injuries.
