Abstract
Abstract A contact medium structure attachable to externally-applied medical diagnostic devices for providing self-adherence of the medical device to the skin of a patient thereby eliminating the need for belts or similar means. The contact medium is inherently adhesive, hydrophilic, skin-compatible, ultrasonic-compatible and pressure sensitive to facilitate self-adhesion of the medical device to the patient's skin. A particularly suitable contact medium is a mesh-reinforced hydrogel film which adheres to the device and extends beyond the perimeter of the device to provide additional adhesiveness and compliance with the contour of the patient's body. A support element associated with and extending beyond the perimeter of the medical device adheres to the contact medium and provides adjustability of the extended hydrogel film relative to the patient's skin.
