Littmann Cardiology IV Stethoscope Hunter Green Tube, 27-inch (6155)

The days of medical staff and professionals in all-white garb are long-gone memories for most of us. Times have changed, along with the availability of house-calls from the local doctor and stethoscopes that were previously only available in black and silver. Stethoscopes retain a familiar and important identity even today, retaining similar but much improved characteristics to their predecessor models, particularly the Littmann Stethoscope range. Since the 1960s, when Dr David Littmann first designed a progressive new stethoscope, the Littmann name has been synonymous with quality medical equipment.

Naturally, Littmann focuses on function as well as form, and providing the best equipment for students, doctors, surgeons, specialists and nurses remains the goal. The Littmann 3M Cardiology IV Stethoscope range is a case in point, where colour choices increase alongside improved performance and function that even the most capable surgeons will appreciate. Mentone Educational provide an unbeatable range of medical devices suitable for students and professionals, and there is no better place to start than a revolutionary 3M Littmann Cardiology IV Stethoscope.

Hunter green tube colour

In an age of equality where we are highly likely to be treated by both male and female medical practitioners, it’s good to know that personal taste is part of the equation. 3M Littmann Cardiology IV Stethoscopes are available in a range of colours to suit the most discerning of doctors, and the earthy hunter-green tube model is certain to impress. Colour may be secondary to some people, but with Littmann it’s part of the whole package where every individual health care professional is worth spoiling for choice. Saving lives is a serious business, and satisfying colour preferences is the least Littmann innovators can do to satisfy the needs of our medical students and staff.

What are the Cardiology IV benefits?

Not all stethoscopes are created equal. The days of two varieties; one for doctors and one for nurses, are no more, and Littmann stethoscopes are tailored to suit individual style and practice preferences. Apart from the appealing colour range, of which hunter-green is proving very popular, there are practical 3M Cardiology IV Stethoscope advantages that are impossible to ignore. Innovative improvements include:

  • Superior capabilities that attenuate (block) unwanted sounds for clearer diagnosis
  • Dual-head diaphragm technology that encourages mistake-free listening
  • Optimised high-frequency and low-frequency auscultation
  • Double lumen channels to minimise friction sound disturbance
  • Easily removed and replaced components for hygienic use and improved appearance

How is next-generation tubing different?

Every component of a Littmann Stethoscope is manufactured with both form and function in mind. Apart from the hunter-green tube colour looking impressive and professional, there are a lot of built-in improvements that need to be experienced to be fully appreciated. Next-generation Littman innovations include:

  • Separate sound paths in the one tube for exacting acoustic performance
  • Zero rubber latex or phthalate plasticisers for comfortable use on sensitive skin
  • High corrosive resistance in contact with skin oils, alcohol and other chemicals
  • Environmentally friendly, ergonomic and recyclable components
  • 7-year guarantee for confident long-term stethoscope use

What are the tuneable diaphragm advantages?

When using a stethoscope with a tuneable diaphragm there is no need to remove and replace chestpiece components. In traditional stethoscopes, the bell (low-frequencies) and diaphragm (high-frequencies) are on opposite sides of the chestpiece, potentially disrupting accurate diagnosis every time the chestpiece is flipped over and repositioned.

With tuneable stethoscopes, both high and low frequency acoustic sensitivity is easily achieved. Movement between bell and diaphragm modes is simply achieved by slight pressure adjustments that affect the diaphragm membrane. Light pressure suspends the diaphragm for auscultation of low-frequency sounds, while a little additional pressure facilitates hearing of high-frequency sounds only.

The best medical innovations are often unseen and unsung heroes. In the case of high-quality stethoscopes supplied by Mentone Educational, the best advertising is the uptake of Littmann Cardiology IV stethoscopes by medical students and professionals around Australia and the rest of the world.
