Indications
The MDF® MD One® Stainless Steel Stethoscope - Pediatric - BlackOut (All Black) is a professional grade diagnostic instrument to be used by health care professionals
Extra-large bell isolates low-frequency sounds (20–100 Hz) like murmurs. Ultra-sensitive diaphragm captures 100–1000 Hz breath and bowel sounds.
Latex-free tubing is thicker to reduce ambient noise and longer to give you more working distance from your patient during auscultation.
Patented headset adjusts for a comfortable fit and a dual-leaf spring adds strength so the headset holds its shape through daily clinical use. US PAT
The patented Acoustic Pyramid Chamber keeps the tubing from kinking or compressing as you move, so the sound channel stays clear and open.
Patented SafetyLock adaptors lock each eartip onto the headset, so tips stay securely in place during exams instead of coming loose.
Soft, pliable silicone eartips in small, medium and large create a secure acoustic seal for a comfortable, custom fit on long shifts.
Request replacement eartips, diaphragms, non-chill rings, retaining rings and name tags anytime, and MDF ships them to you free of charge.
For over 55 years MDF craftsmen have hand-finished our stethoscopes, each one backed by our forever craftsmanship promise.
Can I use the MD One for manual blood pressures in nursing school and clinicals?
Yes. The MD One is designed to transmit Korotkoff sounds clearly for manual blood pressure checks, along with heart, lung and bowel sounds, so it supports you from skills lab through clinicals and beyond.
Do I need a bell, or is a diaphragm-only stethoscope enough for med school?
Having both helps. The MD One true bell is designed for low-frequency sounds and the true diaphragm for high-frequency sounds, and a fully rotating stem lets you switch between them during a full exam.
Why is the MD One chestpiece made of stainless steel?
Stainless steel is dense and durable. The MD One chestpiece is crafted from stainless steel chosen for its acoustic properties and polished to a jewelry-grade finish to hold up to daily use in clinic, on rounds and in the ED.
Will the MD One help me hear heart and lung sounds on a noisy unit?
The MD One uses long, dense, latex-free tubing designed to help block out ambient noise, so heart and lung sounds come through with clarity even when the unit is busy.
What is the patented Acoustic Pyramid Chamber on the MD One?
It is a patented MDF chamber design that helps prevent the tubing from kinking, so sound keeps traveling freely from the chestpiece to your ears whether the stethoscope is around your neck or in your pocket.
Is the MD One comfortable enough to wear for a full 12-hour shift?
It is built for long shifts. The patented ErgonoMax headset is pre-angled for a natural fit and tension-adjustable with dual-leaf spring construction, so it stays secure in your ears without pinching.
What eartip sizes come with the MD One if my ears are small or sensitive?
Three pairs of soft silicone ComfortSeal eartips are included in small, medium and large. Try each size to find a snug seal that blocks outside noise and stays comfortable through long clinical days.
What keeps the eartips from coming off the MD One headset during use?
The patented SafetyLock eartip adaptors are designed to hold the eartips securely on the headset, helping keep them from slipping off while you listen. It is a non-invasive design focused on user safety.
Is the MD One a latex-free stethoscope?
Yes. The MD One is latex-free, including its tubing, making it a fit for latex-free care settings and for clinicians who prefer to avoid latex in the equipment they wear all day.
How durable is the MD One for years of daily clinical use?
The MD One is handcrafted, a stethoscope maker since 1971, using stainless steel and a dual-leaf spring headset built for durability, so it holds up to daily rounds, transport and years of wear. MDF offers lifetime coverage and free parts for life.
What happens when my eartips or diaphragm wear out?
MDF's Free-Parts-For-Life program provides replacement eartips, diaphragms, retaining rings, non-chill rings and ID tags at no cost, so normal wear does not mean replacing your stethoscope.
Does MDF have a contact phone number?
Yes, MDF is located in the United States and has a US phone number. Call Monday through Friday from 8am to 5pm EST to speak with live MDF in-house Client Experience Representatives who are fluent in English and Spanish.
Is the MD One worth buying as an MS1, or should I wait until residency?
It is built to go the distance. A stainless steel dual head design, a spare diaphragm in the box and replacement parts from MDF help one MD One carry you from MS1 through rotations and into residency.
What comes in the box with the MD One stethoscope?
You get the MD One adult stethoscope, three pairs of ComfortSeal eartips in small, medium and large, a spare diaphragm and an ID tag, so you are ready for skills lab and clinicals right away.
Is the MD One a thoughtful gift for a nursing or med school graduate?
Yes. It is a stainless steel dual head stethoscope offered in over 20 color variations, with an ID tag and extra eartips included, a practical gift for white coat ceremonies, pinning and graduations.
