INTRODUCTION
Your new ADC® ADSCOPE™ 641 is designed to be the most versatile and acoustically sensitive stethoscope available.
The Sprague Rappaport design utilizes five different interchangeable chestpiece attachments (3 bells and 2 diaphragms) to detect a broad frequency range in both pediatric and adult patients.
Machined from zinc, then electroplated with chrome and polished to a sterling shine, the chestpiece drum and valve stem eliminate a prime source of acoustic leakage.
The double tube configuration improves acoustic separation, while its 22 inch length optimizes transmission.
Three different eartip styles permit a comfortable, acoustically sealed aural fit for virtually any wearer.
Your ADSCOPE™ 641 is covered by a 5 year limited warranty. When you combine the superb acoustic performance with its extraordinary versatility, you see why the ADSCOPE™ 641 is one of the most popular scopes available.
CHESTPIECE KEY
ADC®’s proprietary chestpiece design and slotted key allows you to tighten the pediatric or adult assembly as securely as you like (to reduce risk of loss) without fear of being unable to disassemble the rim in order to replace a worn or broken diaphragm (a problem that often plagues less costly Sprague scopes). To replace a diaphragm, remove the desired assembly by gripping the assembly firmly and turning counterclockwise. To loosen the diaphragm rim, insert the key into the two slots located within the threaded portion, located on the underside of the assembly. While holding the rim steady, turn the key counterclockwise to loosen the rim. Remove worn diaphragm and replace with new. Reassemble rim, then entire assembly onto chestpiece drum.
