The Stethoscope Sensor Pack contains a SmartQ Stethoscope Sensor and a conventional binaural stethoscope to help students to locate their heart manually and so find the best position for the sensor.
A stethoscope is a listening bell designed to amplify the sounds created by the heart as it beats. In the hands of a trained diagnostician the sounds and the location of the sounds can reveal valuable information about the heart before invasive investigations are started.
The conventional stethoscope is used to listen to the heart or circulatory sounds. The Stethoscope sensor is then used to record the heart sounds and the echoes of the beat in the circulation. With the addition of an ECG sensor and a Heart wave sensor a full physiology of the heart cycle can be recorded and analysed.
The sensor has a diaphragm held onto the sounding bell by a screw ring. The diaphragm increases the intensity of low frequency sound detection, if the diaphragm is removed the higher frequency sounds of the heart beat are detected.
The piece of soft foam is used to hold the chest piece of the sensor in position, this prevents noise from the tremor of the fingers.
The sensor needs to be in contact with the skin for the best response. The best results will come from a logger that can record at an intersample time of 2 ms or faster.
The Smart Q Stethoscope sensor is sold for the purpose of teaching and educational instruction. It is not, and has not been designed to be a medical or diagnostic instrument, results are illustrative only.
All our sensors are supplied with 5 years warranty and lifetime
For customers outside of the UK, please contact Data Harvest or an overseas distributor within your country.
All available downloadable product manuals and firmware for the Stethoscope Sensor Pack
|Ranges||4, Stethoscope, Stethoscope F, Sound mV, Sound F mV|
|Stethoscope ±100 mV||The most sensitive range used for making recordings of the heart beat sound wave.|
|Stethoscope F ±100 mV||Has a low pass filter that reduces the effect of higher frequency sounds that can be created by speech, movement of the sensor over the skin, etc. Use for recording the heart beat sound wave in an area where background noise is a problem.|
|Sound ±1000 mV||A reduced sensitivity range for detection of sound in solids.|
|Sound F ±1000 mV||Has a low pass filter which allows the low frequency sounds to pass through to the logger and removes some high frequency sounds.|
