3M Littmann Classic II Paediatric-Caribbean Blue with Rainbow finish 2153

This is a paediatric stethoscope designed for the auscultation of patients in the pediatric age group. It is constructed with a focus on acoustic performance and patient comfort, utilizing a proven design adapted for younger individuals. The instrument is intended for use by healthcare professionals to assess and monitor the physiological sounds of the body, aiding in diagnosis and physical examination.

Its construction incorporates materials selected for durability and ease of maintenance. The overall length of the stethoscope is 71 cm, and it weighs 105 grams. The tubing is made without natural rubber latex or phthalate plasticizers, contributing to user and patient safety.

The stethoscope operates through the principle of acoustic transmission. Sound waves from the patient's body are captured by the chestpiece, which features a dual-sided design. One side incorporates a tunable diaphragm, allowing for the detection of both high and low-frequency sounds depending on the pressure applied.

Light pressure facilitates the hearing of low frequencies, while firmer pressure enables the perception of high frequencies. The reverse side of the chestpiece provides a traditional bell function for auscultating lower-frequency sounds. These captured sounds are then transmitted through a single-lumen tube to the eartips, which are designed to create an acoustic seal for optimal sound clarity.

The next-generation tubing material is formulated to resist staining from skin oils and alcohol, enhancing its longevity.

Key features of this paediatric stethoscope include high acoustic sensitivity, which is crucial for discerning subtle physiological sounds in smaller patients. The tunable diaphragm is a significant benefit, offering versatility in capturing a wide range of frequencies. The non-chill rim on the chestpiece is incorporated to enhance patient comfort during examinations, reducing potential discomfort from temperature differences.

The single-lumen tubing design is intended to facilitate the clear detection of normal and abnormal bodily sounds and rhythms. The eartips are designed for a comfortable fit and to provide an effective acoustic seal, minimizing external noise interference. The stem includes an indicator for the open side of the chestpiece.

This stethoscope is primarily utilized by medical professionals such as pediatricians, nurses, and other healthcare providers involved in the care of infants and children. It is also suitable for use by caregivers who may be trained in basic auscultation techniques. Typical applications include routine physical assessments, monitoring of cardiopulmonary status, and diagnostic evaluations in pediatric settings, including hospitals, clinics, and private practices.

The instrument's design makes it appropriate for a wide range of physical examinations performed on younger patients.

Important usage notes include ensuring proper placement of the chestpiece on the patient's skin to achieve an adequate acoustic seal. The pressure applied to the tunable diaphragm should be adjusted to optimize the detection of specific frequency ranges. Regular cleaning and maintenance of the stethoscope, following manufacturer guidelines, are recommended to ensure hygienic use and preserve its acoustic performance.

The stethoscope is supplied with an additional non-chill sleeve for replacement or as a spare. The product is supported by a three-year warranty. The tubing is Caribbean Blue, and the chestpiece has a Rainbow finish.
