Cardiology Stethoscope
Description
The Welch Allyn Harvey DLX Triple Head is a full-range cardiology/pulmonary stethoscope with 28\ (71 cm) dual-lumen latex-free tubing and a rotatable triple-head brass chestpiece (low-frequency bell, adult flat diaphragm and pediatric corrugated diaphragm), designed to accentuate important cardiac, pulmonary and vascular sounds without relying on difficult variable-pressure techniques.
Bnefits
Full-range cardiology and pulmonary stethoscope for detailed auscultation of cardiac, pulmonary and vascular sounds.
Triple-head brass chestpiece with bell, adult flat diaphragm and pediatric corrugated diaphragm for flexible frequency selection.
Dual-bore (dual-lumen) tubing provides two uninterrupted sound channels, improving acoustic sensitivity and channel separation.
Trumpet brass chestpiece construction and optimally weighted design enhance clarity of low-, medium- and high-frequency heart sounds and murmurs.
Rotatable binaurals and interchangeable comfort-sealing ear tips help achieve a secure, comfortable acoustic seal.
Not made with natural rubber latex, reducing risk for users or patients with latex sensitivity.
Triple-leaf binaural spring encased in polyurethane allows headset size adjustment while helping prevent breakage.
10-year warranty from the manufacturer supports long-term clinical use and durability.
Indications
Auscultation during physical examination for assessment of heart sounds, murmurs and extra cardiac sounds in adult and pediatric patients.
Auscultation of pulmonary sounds such as breath sounds, wheezes and crackles.
Auscultation of vascular sounds, including bruits and blood flow characteristics.
General diagnostic use by physicians, nurses, cardiologists and other trained healthcare professionals in clinical, hospital and educational settings.
Composition
Trumpet brass triple-head chestpiece with low-frequency bell, adult flat diaphragm and pediatric corrugated diaphragm.
Chrome-plated brass chestpieces and binaurals.
Dual-bore (dual-lumen) latex-free tubing, 71 cm (28") length.
Triple-leaf binaural spring encased in polyurethane for adjustable tension and added durability.
Soft and hard interchangeable comfort-sealing eartips in multiple sizes.
Polycarbonate diaphragm components (flat and corrugated diaphragms).
Head style: rotatable triple-head with bell, flat diaphragm and corrugated diaphragm.
Tubing style: dual-lumen tube delivering separate sound channels to each ear.
Length: approximately 71 cm (28") overall tubing length.
Acoustic performance: cardiology-grade acoustics optimized for low-, medium- and high-frequency heart and lung sounds.
Packaging
Unit carton containing one Welch Allyn Harvey DLX Triple Head stethoscope with black dual-lumen tubing (28"/71 cm).
Includes assorted soft and hard eartips and instructions for use (IFU); accessory kits and replacement parts are available separately from the manufacturer.
Usage
Select and attach appropriately sized soft or hard eartips to the binaurals; insert eartips into the ears pointing slightly forward to align with the ear canals.
Adjust the headset by gently squeezing or spreading the binaurals so that the stethoscope sits comfortably and forms an effective acoustic seal.
Rotate the triple-head chestpiece to select the desired side (bell, flat diaphragm, or corrugated diaphragm) indicated by the index marker.
Use the bell primarily for low- to medium-frequency heart sounds and murmurs; use the flat diaphragm for higher-frequency heart sounds and lung sounds; use the corrugated diaphragm for enhanced low-frequency gallops, rumbles and certain murmurs.
Place the active side of the chestpiece firmly on bare skin over the area to be examined (e.g., precordium, lung fields, arteries) and listen for characteristic sounds.
Avoid excessive pressure that can distort low-frequency sounds, especially when using the bell.
Clean and disinfect the chestpiece and eartips between patients according to institutional infection-control policies and the manufacturer’s instructions for use.
Contraindications
No specific clinical contraindications are listed by the manufacturer for use on intact skin.
Avoid use on open wounds, severely compromised skin or areas where contact pressure from the chestpiece is not recommended.
Use caution in patients with known sensitivities to any contact materials other than latex, although the device is not made with natural rubber latex.
Follow standard institutional precautions for infection control when using on patients with transmissible infections.
Adverse Effects
Potential temporary discomfort or tenderness of the external ear canal from poorly fitted or over-tightened eartips.
Possible skin irritation or pressure marks at the chestpiece contact area in individuals with very sensitive skin or prolonged pressure.
Risk of cross-contamination or infection transmission between patients if the chestpiece and eartips are not adequately cleaned and disinfected between uses.
Small parts such as eartips may pose a choking hazard if detached and accidentally ingested.
Storage Conditions
Store the stethoscope in a cool, dry place at room temperature when not in use.
Avoid prolonged exposure to extreme heat or cold, solvents, oils and direct sunlight, which may damage tubing or plastic components.
Do not autoclave the stethoscope and do not immerse the entire device in liquid; clean using approved disinfectant wipes or solutions according to the instructions for use.
Keep the stethoscope in its case or hung in a manner that prevents kinking or sharply bending the tubing.
Duration
Used intermittently during physical examination and monitoring; duration is limited to the length of the auscultation procedure.
Onset
Immediate acoustic transmission of body sounds during auscultation when the chestpiece and eartips are correctly positioned.
