The Breathing
Sounds Microphone is intended to monitor sounds generated by the
passage of air through airways. Its small size allows placement
on the neck. The cable can be taped to the shoulder and connected
to the Input Cable. Alternately, the unit can be suspended near
the subject. Two isolated SAFELEAD® female 0.059-inch (1.5 mm)
connectors are attached to the cable for connection to the Input
Cable. These are the only connections to be made. The microphone
generates a relatively large signal in response to airflow; approximately
1 to 5 millivolts. A single 1.5-volt battery is used in the battery
holder attached to the cable.

A rugged piezo-electric
transducer which has been designed to reliably monitor and record
peripheral pressure pulses, Korotoff sounds, carotid pulses, small
animal respiratory activity, swallowing and other dynamic biological
functions. Its small size and high signal output make it ideal for
both teaching and research applications. The Model 1010 is easily
attached to the subject at any desired location with the integral
Velcro® strap. This durable transducer is simply and easily connected
to existing direct writing oscillographs, polygraphs, or computer
based data acquisition systems.
