    • An ergonometric chestpiece for a stethoscope adapted to receive auscultatory sounds from a body and adapted to be coupled to an earpiece for a user. The chestpiece is adapted to be grasped by a thumb and at least one finger of the user. The chestpiece has a bottom surface which is generally planar and is adapted to be placed near the body for receiving the auscultatory sounds. The chestpiece has an upper portion opposite the bottom surface. The upper portion has a raised center portion defining left and right indented gripping surfaces which form recesses defined by the left and right indented gripping surfaces and by a surface generally parallel to but opposite the bottom surface. The left and right indented gripping surfaces are adapted to receive the thumb and at least one finger of the user, respectively. The indented gripping surfaces have indented impressions adapted to be easily, securely and comfortably grasped by the thumb and fingers of the user. The indented gripping surfaces are each further defined by a protruding edge on the top surface of the raised center portion which prevent the fingers of the user from slipping upward and thus prevent the chestpiece from slipping out of the user's hand. The raised center portion form a physical stop to prevent the thumb and fingers of the user from slipping forward and contacting the body when the thumb and the at least one finger grasp the raised center of the upper portion. The left and right walls may be concave. The ergonometric chestpiece may be generally circular and the left and right walls are cylindrically concave around axes generally orthogonal to the bottom surface. The top surface of the raised center portion may be sloped with respect to the bottom surface, the top surface being closer to the bottom surface at the front of the chestpiece than at the rear of the chestpiece.
    • 用于听诊器的用于接收来自身体的听诊声音并适于耦合到耳机的用户的听觉器械。 胸部适于被拇指和使用者的至少一根手指抓住。 胸部具有大致平面的底面,并且适于放置在身体附近以接收听诊声音。 胸部具有与底面相对的上部。 上部具有凸起的中心部分,其限定左右的缩进的抓握表面,其形成由左右的缩进的抓握表面限定的凹部以及大致平行于底部表面的表面。 左右的缩进夹持表面分别适于接收拇指和使用者的至少一根手指。 缩进的抓握表面具有缩进的印模,其适于由用户的拇指和手指容易地,牢固地和舒适地掌握。 缩进的抓握表面每个进一步由凸起中心部分的顶表面上的突出边缘限定,防止使用者的手指向上滑动,从而防止胸部从使用者的手中滑出。 当拇指和至少一个手指抓住上部的凸起中心时,凸起的中心部分形成物理停止以防止使用者的拇指和手指向前滑动并接触身体。 左右壁可以是凹的。 纬度计胸部可以是大致圆形的,并且左右壁围绕大致垂直于底面的轴线圆柱形凹入。 凸起中心部分的顶表面可以相对于底面倾斜,顶表面比在胸部的后方更靠近胸部前方的底表面。
