Abstract

An ultrasound acoustical coupling pad comprising, a retaining member comprising a sheet having a front surface, a back surface, and a cut-out. The pad has a doppler transducer received in the cut-out, and a strip of acoustical gel covering at least a substantial portion of the front surface of the retaining member. The pad has a backing member comprising a sheet secured to the retaining member and having an edge portion extending outwardly from the retaining member and strip, with the edge portion having adhesive on a front surface thereof to secure the pad to the skin of a patient.

Claims

1. 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.

2. The pad of claim 1 including a doppler device electrically connected to said transducer.

3. The pad of claim 2 including a spectrum analyzer electrically connected to the doppler device.
