Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
An ultrasound acoustical coupling pad, comprising: a circular planar retaining member comprising a sheet of foam having a front surface free of adhesive on the front surface, a back surface, and a cut-out; a doppler transducer received in said cut-out and with the retaining member in direct contact with the transducer; a circular strip of acoustical gel covering the front surface of the retaining member; a sheet releasably covering a front surface of the strip; a backing member comprising a sheet of flexible material covering the entire back surface of the retaining member and having an exposed edge portion extending outwardly from the retaining member and strip peripherally around the retaining member and strip, said backing member having adhesive on a front surface thereof to secure the backing member to the back surface of the retaining member and secure the edge portion to the skin of a patient, said backing member overlying the transducer; and a release sheet releasably covering the adhesive on the edge portion of the backing member.
