Pressure Ulcer Boot

Description:

Project ID: D2022-32           

Background

Pressure ulcers or bedsores form when there is a loss of circulation due to prolonged pressure at a point, such as on the heel of the foot. This occurs in immobile patients, such as those confined to a bed or wheelchair. A common way to prevent pressure ulcers is to change the position of the patient with the assistance of a caregiver. Devices have also been developed that shift pressure away from heel, but they create new pressure points at risk of developing into ulcers. Therefore, there is a need for a device that can continuously change the location of the pressure points.

Invention Description

Caregivers at the University of Toledo developed a pressure ulcer boot that continuously changes pressure points in a “rolling” motion. This is accomplished through an array of selectively inflatable and deflatable air pockets within the body of the boot.

Applications

  • The Pressure Ulcer Boot (referred to in shorthand as the PUB) is a non-invasive, easy-to-use, automated device equipped with a pressure changing system to help prevention of pressure ulcers in the foot.

Advantages

  • Weight is offloaded to multiple and changing points
  • Increases circulation in the lower extremities of a bed-ridden individual
  •  Simulates biophysical mobility for individuals with prolonged immobility
  • Alters body pressure points continuously, changes the pressure points on all segments covered by the device without shifting pressure points from one area to another.
