BPL Stethoscope - DIA Cast Adult Black (ST-01)

BPL Dia Cast Stethoscope – Adult Black (ST-01) is a entry-level acoustic stethoscope for adult auscultation: outpatient departments, general wards, nursing stations, general practice and student kits. Its DIA Cast single-sided chestpiece provides bell and diaphragm-frequency responses for versatile clinical examinations. This BPL stethoscope features a non-chill rim for patient comfort, a medical-grade PVC tube, and soft-sealing eartips for a comfortable fit. Its lightweight construction supports routine use in clinical and patient-monitoring settings.

Light contact favours low-frequency sounds, the range a traditional bell is used for; firmer pressure brings out higher-frequency sounds, the diaphragm range. A single-lumen medical-grade PVC tube carries the sound to an anatomically angled headset, which directs the eartubes forward into the ear canal. Soft-sealing eartips close the acoustic path and reduce ambient noise. The tube is black; the chestpiece has a polished finish.

Most reliable for routine examination of heart, lungs and bowel sounds, and Korotkoff sounds during manual blood-pressure measurement.

Features:

• Dual-Frequency Single-Sided Chestpiece: Bell and diaphragm-frequency responses support assessment of heart, lung, and other body sounds.
• High Acoustic Sensitivity: Features optimized acoustic clarity and sound transmission.
• Patient Scope: Designed for routine examinations of adult patients.
• High-fidelity signal: A single-lumen medical-grade PVC tube is designed to maintain high signal fidelity, minimizing ambient noise.
• Patient comfort: The non-chill rim helps make chestpiece contact more comfortable.
• Comfortable Acoustic seal: Soft-sealing eartips support a comfortable fit during examinations.

• Chestpiece: Die-cast metal alloy with a polished finish.
• Diaphragm: Rigid polymer disc, retained by a non-chill rim.
• Tubing: Single-lumen medical-grade PVC; Phthalate status.
• Binaurals (headset tubes): Metal with a tension spring.
• Eartips: Soft polymer.

Intended to be used by healthcare professional only.

1. Fit the headset. Hold the binaurals so the eartubes angle forward, towards your nose, and seat the eartips in the ear canals. The tips should seal without pressure; if sound is faint, check the angle before checking the chestpiece.
2. Check before each use. Look for cracks in the tube, a loose or damaged diaphragm, and eartips that no longer seal. Tap the diaphragm lightly to confirm sound reaches both ears.
3. Choose the frequency range by pressure. The ST-01 has one chestpiece face. Rest it lightly on the skin for low-frequency sounds (third and fourth heart sounds, some murmurs); press firmly for higher-frequency sounds (first and second heart sounds, breath sounds, bowel sounds).
4. Place the chestpiece on skin, not over clothing, at the standard auscultation sites. Keep the tube from rubbing against clothing or skin during listening; friction noise is the commonest artefact.
5. Blood pressure. For manual measurement, place the chestpiece over the brachial artery below the cuff edge and listen for Korotkoff sounds while deflating the cuff at 2 to 3 mmHg per second.
6. Clean between patients. Wipe the chestpiece, rim and eartips with a 70% isopropyl alcohol wipe and let them dry.
   
7. Store at room temperature away from direct sunlight and heat. Avoid carrying it against bare skin for long periods; skin oils stiffen PVC tubing over time.

• Inspect the tubing, chestpiece, and eartips before each use.
• Clean and disinfect patient-contact surfaces between examinations using compatible products.
• Avoid immersing the instrument in liquid or exposing it to unsuitable chemicals or excessive heat.
• Do not use damaged components, and replace them as appropriate.
