Phonocardiographs Manufacturing

A phonocardiograph is an electroacoustic machine that helps record the sounds and murmurs of the heart. There is little noise and distortion and you can audio monitor with the built-in speaker. Operating a phonocardiograph is very simple. You place the electronic sensor onto the patient’s chest. The selectors then have to be adjusted depending on what pitch and intensity the user desires. The sounds of the heart will be played through the built-in speaker. The flashing LED indicator also provides audio-visual indication.

The phonocardiographs manufacturing of sound is very simple. It is just made up of a system of microphones, amplifiers, and recording devices. The microphones are connected to filters that allow both low and high frequency sounds to be recorded. The user will also use audiphones to ensure that a clear accurate recording has been made. Phonocardiographs are often used to diagnose and monitor heart conditions. The technique that creates a graphic record of the heart is known as phonocardiography.

  1. 1ST Portable/pocket-sized Stress Test Device:
    By obtaining a “diastolic stress test Using an external pressure transducer over cardiac beat & Isometric Exercise” (Presso Test), every practitioner could detect asymptomatic patients with early myocardial disease in daily practice. This test is based on exactly defined criteria (US patent 7,107,095B2, 2003) and has a fear sensitivity (>72%) according to >60 publications in US and European Journals. This test is safe and has a firm pathophysiologic basis. Specifically, this simple and widely applicable stress test could become a useful diagnostic tool for screening Coronary Artery disease in earliest “silent” phase. This system can be included in a Phonocardiograph or Elec. Stethoscope too by filtering the lower frequencies. I am wiling to co-work with you in developing a new or modifying your device.
