3M Littmann Select, Burgundy The thin bell makes it easy to auscultate during blood pressure measurements. By adjusting the pressure applied to the chestpiece against the skin, you can switch between low-frequency and high-frequency modes, allowing for continuous auscultation of low and high frequencies without changing the chestpiece side. I am a healthcare professional, and there are no issues with auscultation. I have used it for about a year, and the tubing has not hardened, it is as soft as when it was new. The rim & diaphragm have been replaced with the ones in photo 7. It is also possible to ship it with the Littmann rim & diaphragm, as shown in photo 8, but in that case, it will be +¥1,700. Disinfected with alcohol swabs before listing. Useful not only for medical professionals, but also for auscultating children's lung sounds, and for early detection of aspiration pneumonia in home care. Will be shipped in simple packaging. #Stethoscope #NursingStudent #Nurse #Nursing #Littmann #Littman #litmann #litman #Caregiving #Facility #FetalHeartSounds #Doctor #Clinic - Brand: Littmann - Model: Select - Color: Black Thank you for viewing.
