    Abstract: 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.

    Abstract: 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.

The outer wall portion includes an outer lower edge forming an outer lower edge perimeter that establishes a bottommost plane. The stethoscope chestpiece also includes a second major cavity formed from a portion of an inner wall portion having an immobilizing element disposed thereon, the second major cavity is within the first major cavity, and a portion of the immobilizing element is spaced-apart with a portion of the outer lower edge perimeter. The first major cavity volume is at least two times a second major cavity volume.
