  • 听诊高频和低频声音

    各种听诊声音在低频和高频范围内占据一定的区域。如图所示,其中一些频率基本上彼此重叠。因此,临床医生必须分离高频和低频声音,并用听诊器检测和区分细微的声音。

  • 听诊高频和低频声音

    悬浮式可调振动膜技术使听诊更有效。通过调整施加在胸件的压力,临床医生可以分离出每个频率范围来判定细微的声音。

    轻压可以听取低频音源,加大压力则会限制听诊膜移动,阻止低频音源,从而能够听取高频音源。

    此外,悬浮式可调振动膜技术对于用户来说简单易行——无需为了听到不同频率的声音而移除、反转和重新定位胸件。

  • 悬浮式可调振动膜技术的优势

    方便性: 只需更少时间定位听诊器,便可听诊各种频率的声音

    比较性: 低频和高频音源分离有助于进行关键比较,提供有价值的评估。

    一致性: 您不必担心将听诊膜放在发现异常的部位。只需施加压力。
