    • The invention concerns a diaphragm for the hygienic protection of a stethoscope formed by a thin and flexible latex or rubber cap, provided with a gripping hem (28) at its periphery. The diaphragm (26) has substantially the same diameter as the auscultation attachment to be protected. A ring-shaped cavity (30) is provided between the hem (28) and the back wall (32) facilitating the symmetrical adaptation of the diaphragm (26) on the attachment peripheral edge. The assembly is arranged so that the hem (28) matches perfectly the edge outline without the need for stretching and elastic deformation by drawing when said diaphragm (26) is set in place.
    • 本发明涉及一种隔膜,用于由薄而柔性的胶乳或橡胶帽形成的听诊器的卫生保护装置,其在其周边设置有夹持下摆(28)。 隔膜(26)具有与被保护的听诊附件基本相同的直径。 一个环形空腔(30)设置在折边(28)和后壁(32)之间,有利于膜片(26)对附件周边边缘的对称适应。 组件被布置成使得边缘(28)完全匹配边缘轮廓,而不需要在所述隔膜(26)设置就位时通过拉伸而需要拉伸和弹性变形。
