Narrative: A digital version of the classic Littmann stethoscope used by physicians and nurses throughout Canada. (From Acquisitions Worksheet, see Ref. 1)

An electronic and digital version of the classic stethoscope first developed by Dr. David Littmann in 1961, this instrument rapidly became popular: it's simple design remains the basis for most stethoscopes used in medical practice today [2016]. It's open chest piece allows the user to better hear low-pitched sounds; firm tubing has a single lumen bore; it is constructed of the shortest practical overall length; has a spring with precise tension to hold the ear tubes apart; and is lightweight and convenient to carry and use. It was made in two models: the doctor's stethoscope and the nurse's stethoscope.” (From Acquisitions Worksheet, see Ref. 1)
