An auscultation device having a chest piece with a sound output aperture in fluid communication with a diaphragm on a bottom surface of the chest piece. A digital stethoscope component with a sound input aperture and a connector fluidly connecting the sound output aperture to the sound input aperture. The connector is designed such that the auscultation device is free standing on a horizontal surface.

Layers of siloxane tackifying resins that do not contain siloxane fluids, gums or polymers act as adhesion promotion agents. Articles include a substrate layer, a non-tacky siloxane tackifying resin adhesion promotion layer disposed on the surface of the substrate layer, and a crosslinked siloxane layer in contact with the adhesion promotion layer. The crosslinked siloxane layer is not an adhesive layer. The adhesion of the crosslinked siloxane layer to the substrate is greater than the adhesion without the non-tacky siloxane tackifying adhesion promotion layer.

Aspects of the present disclosure relate to an ergonomic chestpiece for a stethoscope. The chestpiece includes a bottom surface which is generally planar and adapted to be placed near the patient for receiving auscultatory sounds. The chestpiece includes a raised center portion defining first and second lateral indented gripping surfaces, the raised center portion having a top surface opposite the bottom surface. The chestpiece includes a stem portion extending distally from the raised center portion. The first lateral indented gripping surface is defined by a first wall comprising a first concave surface arcuate about a first axis and the second lateral indented gripping surface is defined by a second wall comprising a second concave surface arcuate about a second axis. The first axis and the second axis form a V-shape comprising an apex oriented in a direction of the stem portion.

A stethoscope includes a flexible chest piece including a top surface, a bottom surface, a side surface defining a slope between the top surface and the bottom surface, and a groove extending along an inner circumference of the chest piece. A diaphragm is positioned within the groove.

An electronic stethoscope includes a housing configured for hand-held manipulation, a transducer supported by the housing and configured to sense auscultation signals at a first location, and a headset coupled to the housing and configured to deliver audio corresponding to the auscultation signals through earpieces on the headset. The electronic stethoscope further includes a processor disposed in the housing and configured to convert the auscultation signals to first digital signals representative of the auscultation signals and to wirelessly transmit the first digital signals from the electronic stethoscope via a secure digital network to a second location such that the audio corresponding to the auscultation signals is provided to headsets of one or more additional electronic stethoscopes at the second location in substantial real time with the sensing of the auscultation sounds at the first location.

A bioacoustic sensor assembly is described including a transducer generating an acoustic signal and an actuator configured to deform a portion of the transducer to increase a signal-to-noise ratio of the acoustic signal. The disclosure also provides methods and systems for reducing the impact of noise vibrations at the transducer.

An ear tip is adapted to deliver sound to an ear canal. The ear tip includes a first section, a second section and a third section. The first section is connectable to a sound-transmitting device. The second section has a first end, a second end and walls defining a bulbous section. The first end is connected to and in open communication with the first section. The second end is connected to and in open communication with the third section. The third section includes walls defining a flume and an outlet port adapted for open communication with the ear canal. The outlet port has a maximum outer diameter of about 11 millimeters. In a relaxed state, a ratio of a maximum outer diameter of the second section to a maximum diameter of the third section is between about 1.25 and about 2.5.
