    • A hand-held device (10) for creating a pressure change in a person's ear canal. It has an interior space forming an air chamber (50), a plunger (58) and a valve means (52) frictionally engaged with said plunger (58), a tube (14) with an earpiece (48), and a finger-actuated diaphragm (60) in an external wall of the air chamber (50). The diaphragm (60) moves the plunger (58) from a resting position, and in a first direction. A spring (56) returns the diaphragm (60) to its undepressed position. Initial movement of the plunger (58) in said first direction from said resting position displaces the valve (52) from a first position to a second position at which the valve means (52) is stopped from further movement in said first direction. Further movement of the plunger (58) in said first direction causes the plunger (58) to slide relative to the valve (52). The device (10) is intended for treatment of Mënière's disease and ear pain from other causes.
    • 一种用于在人的耳道中产生压力变化的手持装置(10)。 它具有形成空气室(50),柱塞(58)和与所述柱塞(58)摩擦接合的阀装置(52)的内部空间,具有耳塞(48)的手指管(14) 在空气室(50)的外壁中的致动隔膜(60)。 隔膜(60)使活塞(58)从静止位置和第一方向移动。 弹簧(56)将隔膜(60)返回到其未受压位置。 柱塞(58)沿着所述第一方向从所述静止位置的初始移动将阀(52)从第一位置移位到第二位置,在该位置处,阀装置(52)停止在所述第一方向上的进一步移动。 柱塞(58)沿所述第一方向的进一步运动使得柱塞(58)相对于阀(52)滑动。 设备(10)旨在用于治疗梅内尔氏病和其他原因引起的耳痛。
