THE PROBLEM
Those with spinal cord injuries are often plagued with painful and costly secondary conditions, such as pressure ulcers and wounds to the skin due to prolonged pressure from sitting in a wheelchair. While air-filled cushions are a commonly recommended treatment, the cushion's effectiveness depends on its pressure being properly inflated and evenly distributed, which those without sensation are unable to detect. This means that caregivers must check the patient's skin and manually reposition the patient's body to avoid skin deterioration.
OUR SOLUTION
Researchers at The University of Alabama have developed an air cushion that automatically senses the weight distribution of a patient as well as the air pressure inside the cushion. The sensor data is processed in real-time by algorithms that recognize cushion inflation and prolonged uneven medial-lateral weight distribution. It also provides audio and visual alerts of existing dangerous conditions. All of the sensor data is stored to an SD card and can be used to track weight changes and ulcer risk.
THE ADVANTAGES
- Provides a better analysis by tracking both the weight distribution and air pressure in relation to weight
- Tracks data in real-time and provides immediate feedback
- Capable of being added to any wheelchair design, both manual and powered
- Reduces risk of patient developing secondary health issues
- Ultimately saves patient, insurance, and healthcare system money through proactive intervention
