Abstract

The biological sounds monitor (100) comprises a piezoelectric membrane (105) and a mechanical assembly. The latter mechanical assembly includes a membrane support (101) on which the piezoelectric membrane is mounted, and a wave-propagating mechanism (108) disposed on one side of the piezoelectric membrane. Upon use of the biological sound monitor, the wave-propagating mechanism is interposed between the piezoelectric membrane and an examinee's body to propagate acoustic waves from the examinee's body to the piezoelectric membrane. Advantageously, the membrane support comprises a piezoelectric membrane tensioning mechanism.

Claims

AMENDED CLAIMS[received by the International Bureau on 1 1 January 2002 (11.01.02); original claim 1 amended; remaining claims unchanged (1 page)]
1. A biological sounds monitor comprising a piezoelectric membrane and a mechanical assembly, wherein said mechanical assem ly comprises;
- a membrane support on which the piezoelectric membrane is mounted; and
- a resilient wave-propagating mechanism mounted to said membrane support over one side of the piezoelectric membrane and which, upon use of the biological sounds monitor, is interposed between said piezoelectric membrane and an examinee's body to propagate acoustic waves from the examinee's body to the piezoelectric membrane.
2. A biological sounds monitor as recited in claim 1 , wherein the membrane support comprises a piezoelectric membrane tensioning mechanism.
3. A biological sounds monitor as recited in claim 1 , wherein the piezoelectric membrane is a piezoelectric disk formed with an annular peripheral portion having a first side with a convex cross section and a second side with a concave cross section, and wherein the membrane support comprises:
- a cylindrical base having an annular distal edge face defining a circular groove to receive the first side of the annular peripheral portion of the piezoelectric disk;
