Abstract

An elastomeric pad structure coupled to an ultrasonic transducer provides excellent coupling and transmission for extradermal applications without requiring the glycerin gel couplant typically used for such applications. The material and shape of the face of the pad structure traps a small amount of liquid between the pad and the skin, providing an effective couplant not requiring further containment, rewetting, or clean-up. The elastomeric pad be releasably coupled to the ultrasonic transducer, and the various illustrative embodiments for coupling include the use of clips, adhesives, an adapter ring having a lip or grooves, a ring having pins for engaging holes in the elastomeric pad and the transducer, and a sleeve which employs pressure or friction to retain the elastomeric pad to the transducer. Uses for the system and method include extradermal applications such as ultrasonic bone growth stimulation through a window cut in a bone fracture cast.
