Abstract
The present invention is a stethoscope which provides the user with continuous access to physiologic sounds. The stethoscope consists of multiple, lightweight, disposable sound receiving sensors and shutoff valves which allow selective auscultation of specific sites without patient disturbance. In addition, depending upon the positions of the shutoff valves, the stethoscope may enhance sound conduction by producing constructive interference of sound waves. A means of attaching the sound receiving sensors to the skin is also described. Because the sound receiving sensors are disposable, the risk of infection due to cross-examination is minimized. Therefore, this invention is safer than known stethoscopes.
