原创 Heart-Sound Sensor

HKY series of Heart-Sound sensor can give High-fidelity output, using micro-sound components made from new polymer materials to acquire heart beating and other surface arterial pulse signal, then processing it through a high-integrated signal processing circuit, with stability, consistency characteristics.

The products can be widely used in various types of heart-sound acquisition equipment.

HKY series of heart sound sensor list:

<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" /><?xml:namespace prefix = w ns = "urn:schemas-microsoft-com:office:word" />HKY-06A Heart-Sound sensor integrated micro-sound components which is made from new polymer materials, can output low-impedance power signal that can directly drive headphones, and also can connect the computer to recording. By the sound-recording software we can record heart sounds, watch the signal pattern and process pattern analysis.

The product can be used for clinical auscultation, heart-sound analysis, pattern analysis of heart-sounds, and other fields.
