What Is a Dual Head Stethoscope and Why Does It Matter?
A dual head stethoscope has two auscultation surfaces on one chest piece: a diaphragm and a bell. The Deluxe Dual Head Stethoscope (STJDD/STHDDH, VM-STJDD) has a silver dual head with a 47mm adult head diameter, which gives standard acoustic coupling for adult chest wall auscultation. The diaphragm picks up high-pitched sounds such as breath sounds and normal heart sounds. The bell picks up low-frequency sounds such as third and fourth heart sounds and the low-pitched rumble of mitral stenosis. Having both surfaces lets the clinician cover the full range of sounds in a systematic physical examination.
Lightweight Design and Tubing for Daily Clinical Use
At 110g, the STJDD is a lightweight instrument, practical for long clinic sessions, ward rounds and home visits. The standard Y-tubing is 54cm long, which allows comfortable positioning during auscultation without the acoustic degradation associated with excessively long tubes. The black Y-tubing carries sound through the binaural tubing assembly to the earpieces. The single unit is packed in a compact 190 × 100 × 20mm box, so it is easy to store and carry as a standard item of clinical equipment. CE and ISO approvals confirm compliance with international quality standards for clinical diagnostic instruments.
