Abstract
Abstract Blood pressure measuring device having an inflatable cuff, a buckle and a sound pickup whose blood-pressure-related signals are either directly recognized and correlated with a pressure readout or processed by an electric circuit and delivered to at least one readout means giving the blood pressure values. The buckle forms one unit which houses the readout means and the electrical circuit for the conversation of the sound signals.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
In a sphygmomanometer having a microphone, readout means for displaying blood pressure values, a circuit receptive of the signals from the microphone for producing an output applied to the readout means, an inflatable cuff band and means forming a buckle for the cuff band, the improvement wherein: the buckle forming means comprises a housing accommodating the readout means and circuit, means permanently attaching one end of the cuff band to the housing and means defining an elongated slit at least adjacent to the housing through which the free end of the cuff band is received; and the microphone is connected to the cuff band and spaced from the buckle.
