3M Littmann Classic II Pediatric Stethoscope Analysis Report

Device Identification

The examined images belong to an acoustic stethoscope, which is a medical diagnostic device. The device has an integrated structure consisting of headset, tubing, and chestpiece components. Additionally, the product’s original box and spare part accessories are also present in the images.

Brand and Model

The product’s box and its characteristic features have been examined in detail. The identified brand and model information is as follows:

• Brand: 3M Littmann
• Model: Classic II Pediatric

On the box in the images, “Littmann Brand”, “Classic II Pediatric Stethoscope” and “L” logo emblems are clearly legible. The product is from the Classic II series, designed by the brand for children (pediatric use). Furthermore, while the model image on the box is black, the product inside the box is Red. It is understood from the product box that the packaging is used for general series promotion without distinction by model, and the color of the product inside is different.

Authenticity Assessment

The product is highly likely an original 3M Littmann product. This opinion is based on the following observations:

• The print quality of the Littmann logo on the chestpiece (diaphragm) and the circular arrangement of the “LITTMANN QUALITY” text are consistent.
• Box printing and fonts comply with brand standards.
• The phrase “Made in U.S.A.” is engraved on the metal part of the chestpiece.
• The structure of the eartips and the angle of the connecting metal tubes are consistent with the original design.
• The gray “non-chill rim” gasket on the chestpiece is smooth and fits perfectly.

Areas of Use

Being a “Pediatric” model, this product is specifically designed for the examination of child patients. The diameter of the chestpiece is smaller than that of adult stethoscopes (typically around 1 inch), which has been developed to better fit children’s body anatomy and to hear heart/lung sounds more clearly. It is suitable for use by pediatricians, family physicians, medical students, and nurses.

General Condition and State

The cosmetic and physical condition of the device can be evaluated as “New” or “In Box, Unused/Very Lightly Used” (New Old Stock – NOS). It is observed that the product rests in its own box, in a custom-cut foam insert, and the spare accessories are unopened in a sealed bag.

Physical Deformation Examination

During a detailed visual inspection of the product, no significant damage was found:

• Tubing (Lumen): No cracking, drying, discoloration, or breakage has been observed in the red rubber tubing. The tubing maintains its natural “U” shape.
• Metal Parts: No corrosion, rust, or deep scratches are present on the stainless steel parts of the binaural tubes and the chestpiece. They retain their luster.
• Plastic and Rubber Parts: No deformation or yellowing is observed on the eartips and the gray gasket around the diaphragm.

Accessories and Quantity Information

The total product and accessory breakdown in the images is as follows:

• 1 unit 3M Littmann Classic II Pediatric Stethoscope (with red tubing)
• 1 pair (2 units) of spare eartips (Gray colored, in its original sealed transparent bag)
• 1 unit Original Product Box (with inner foam protector)

Technical Specifications and Diaphragm Analysis

The product has a dual-sided chestpiece:

• Wide Side (Diaphragm): Features the Littmann logo, used for listening to high-frequency sounds. A gray non-chill rim is present around it.
• Narrow Side (Bell): Is bell-shaped, used for hearing low-frequency sounds. This part is also clearly visible in the images, and the metal craftsmanship is smooth.

Year of Manufacture and Label Information

On the left side of the box, there is a special logo with the inscription “40 years 1967-2007”. This information strongly indicates that the product or its packaging was produced during the 40th-anniversary celebrations in 2007 or features a packaging design from that period. This suggests that the product could be an older production (New Old Stock) item that may carry “Vintage” or “Collectible” value.

Potential Failure Risk

No immediate usage-preventing damage is visible in the images. However, considering the possibility of the product’s old manufacturing date (referencing the 2007 logo on the box); the potential for the rubber tubing and eartips to lose their elasticity over time should be taken into account. Although the tubing appears sturdy and flexible in its current visual condition, the possibility of material aging (hardening) due to long-term shelf life is not zero. Visually, the device appears fully ready for use and robust.
