The BSL Stethoscope was developed to teach students the standard procedure for listening to heart sounds and Korotkoff sounds with a normal stethoscope and at the same time record sound data. A microphone in the stethoscope simultaneously records the sound the student is hearing, and the BSL software will display the soundwave during and after recording.
No calibration required, just select a Stethoscope Preset (Heart or Korotkoff Sounds). If ECG is also recorded, the timing of the heart sounds with the ECG can be correlated.
The SS30L and SS30LA have the same form and function; the difference is an internal ID used by the BSL software.
The BSL Stethoscope (SS30L or SS30LA) can be used with the Blood Pressure Cuff (SS19L or SS19LB) to record Korotkoff sounds for easy determination of systolic and diastolic blood pressure. With this combination, it is easy to obtain very accurate and repeatable results—usually within 10% of those determined by direct measurement.
Note: For research applications, the SS17L Physiological Sounds Microphone may be a more versatile option.
The Ventilator Validation Kit supports new prototype development, existing design validation for production testing, mobile field testing and verification, and other uses where accurate pressure and flow measurements are critical. The Ventilator Validation Kit provides ventilator manufacturers and prototype developers with a complete solution for validating new medical/hospital-grade ventilator products intended for human use. The VVK100-SYS includes […]
