The LTOD15 (Leytemed LTOD15) is a rechargeable electronic digital stethoscope for clinical cardiopulmonary auscultation. It offers 24X sound amplification, advanced noise reduction (ANR), OLED display, Bluetooth connectivity, and built-in recording/playback for use in hospitals, clinics, and home monitoring.
Audio range: 20 Hz–1000 Hz. Attenuation: ≤12 dB (100–500 Hz) and ≤20 dB (600–1000 Hz). Distortion rate is <1.5% and maximum amplification is 24X for clearer heart and lung sounds.
The LTOD15 supports at least two main modes: heart (cardiac) and lung (pulmonary) auscultation. Mode switching is provided to optimize frequency response and filtering for each application.
ANR reduces ambient and environmental noise so the practitioner hears a cleaner signal, improving clarity and diagnostic confidence—particularly useful in busy clinical environments.
Yes — the LTOD15 has built-in recording and playback capability. Recordings can be played back on the device and transferred wirelessly over Bluetooth to a paired intelligent terminal. Refer to the user manual or companion app for file format, storage location, and export instructions.
Turn on the LTOD15 and enable its Bluetooth pairing mode (see the OLED screen prompts). On your phone/tablet, open Bluetooth settings, locate the LTOD15 in the device list, and pair. For best results use the recommended app or follow the manufacturer pairing instructions in the manual.
Package contents include 1 x Leytemed LTOD15 digital stethoscope, 1 x 3.5 mm specialized earphone (dedicated Bluetooth headset for hygienic use), and 1 x USB charging cable. Packaging is supplied in a carton box.
The LTOD15 uses a rechargeable Li‑ion battery and charges via the included USB cable. Charging time and runtime depend on usage and settings—consult the user manual for typical charging time and battery care recommendations.
Battery life varies with amplification level, recording use, and Bluetooth streaming. The exact runtime is provided in the product manual or datasheet—check those materials or contact the seller/manufacturer for typical figures.
Clean the diaphragm and ear tips with a soft cloth dampened in 70% isopropyl alcohol or a manufacturer-recommended disinfectant. Do not immerse the device in liquid, avoid harsh solvents, and remove ear tips if necessary to clean thoroughly. Follow infection-control protocols in clinical settings.
Yes. With 24X amplification and ANR, the LTOD15 improves auscultation quality even through light clothing, but best acoustic results are obtained with direct skin contact when clinically appropriate.
The LTOD15 weighs approximately 109 g. The diaphragm diameter is approximately 56 mm (about 1.43 in), providing a suitable contact area for cardiopulmonary auscultation.
The LTOD15 connects to Bluetooth-enabled intelligent terminals (smartphones, tablets, PCs). Compatibility depends on the Bluetooth profile and any companion app—check the manufacturer’s compatibility list or app store listing for iOS/Android requirements.
Warranty, replacement parts, and firmware-update procedures are provided by Leytemed or your authorized distributor. Refer to the warranty card and user manual, or contact the seller/manufacturer support for service, replacement ear tips, or software/firmware updates.
