Chestpiece Options
The ADC Sprague design utilizes five different interchangeable chestpiece attachments
(three bells and two diaphragms) to detect a broad frequency range in both pediatric and
adult patients. The chestpiece drum accommodates two different chestpiece attachments
of your choice at one time. Select the type that best suits the intended patient application.
Adult diaphragm assembly - for filtering out lower frequencies
and accenting the higher ranges in adults.
Pediatric diaphragm assembly - for detecting high pitched
murmurs in infants and children.
1 1/4" bell - for detecting low and medium pitched sounds
and murmurs in adults.
1" bell - for detecting low and medium pitched sounds and
murmurs in children.
3/4" bell - for detecting low and medium pitched sounds
and murmurs in infants.
Chestpiece attachments can be affixed by threading clockwise
until tight. To remove, twist in a counterclockwise direction.

Selection of the Chestpiece
On ADC Adscope Spragues, the entire chestpiece rotates 180°,
allowing for the selection of one side at a time. Only one side is
operable at a time. ADC's patented valve mechanism eliminates
virtually all acoustic leakage from the inoperable side.
To select the side in operation, hold the chestpiece stem in
one hand and rotate the chestpiece with the other hand until a
click is felt and heard. A light tap on the diaphragm or bell will
help determine which side is in operation as well.
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).
Replacing the Diaphragm
To replace a diaphragm, remove the desired assembly by
gripping the assembly firmly and turning counterclockwise.
