The reviewer at forusdocs didn't think that Spragues were that bad. In fact the Omron model won the "Best Buy" award. I don't know what allnurses forum's rules are about "hot links" so I posted a link of this review below without the www. P.S. I have no financial interest in the website or Omron.
Bested only by the Littmann Cardiology III. The authors of this review were very complementary of the Omron Sprague-Rappaport. Truth of the matter is that the Sprague-Rappaport by Hewlett Packard was the Littmann Master Cardiology
of its' time. If you are using one, you're just kickin' it old school.
Use what works best for you. It's a pet peeve of mine that healthcare professionals feel that they need to spend $160-170 to get a top of the line Master Cardiology when a stethoscope that costs less than $20.00 will do.
P.S.- If you prefer the Sprague-Rappaport style. MDF Instruments has a deal where they will give you free replacement parts to your stethoscope for life. They are a little more spendy ($25.00-35.00 range) however the cost of replacement eartips can add up.
Helpful & inexpensive stethoscope modifications:
P.P.S. - If the eartips on your stethoscope are not staying on, wrap Teflon Plumbers Tape around the threads once or twice prior to putting the eartips on the binaurals. This will keep them snugly on the binaurals & help prevent them from falling off.
P.P.P.S - If the diaphragm ring on your Sprague Rappaport keeps coming loose & is falling off. Use a little moderate-strength (blue) thread-lock,(e.g. Loctite) on the threads of the diaphragm ring. This will keep the diaphragm ring firmly on the stethoscope & if you need to remove it, you can with a wrench or vise-grips.
