Abstract
A perianal support device includes a central support element with an apex having a continuous contact surface along the apex to interface with a patient's perianal tissue. Compression elements extend laterally away from each apex side of the central support element. Each compression element may have a narrower proximal end to the central support element and a wider distal end, and be flexible to bend to the gluteal cleft anatomy. The surface of each compression element that faces the patient in use may be covered, at least partially, with a loop material on the wider distal end. Each compression element may also have the opposite surface covered, at least partially, with foam. The central support element and compression elements may be integrally formed. A gripping tab is also provided at a distal end of each compression element, providing an easy location for medical staff to grasp for placement and removal.
