Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
Apparatus for telephonically transmitting the standard electrocardiographic leads, characterized by the fact of comprising a compartment in which to contain a telephonic acoustic transducer, of miniaturized self-powered type, provided with electrical connections (3) that can be linked to the input of the said transducer and terminate at an electric circuit comprising a pushbutton panel (4) with which to select the various standard electrocardiographic leads forthcoming by a patient cable, the said apparatus also comprising a cavity (11) for supporting therein a receiver of a telephone.
Claim 2
Dependent Claim
85 words
