    • A disposable protective cover (100) for application to an applanation tonometer head (20) of a Goldmann-type applanation tonometer (10). The disposable protective cover (100) may be bag like in contour or preferably pre-formed into a frusto-conical contour having a planar surface (102) bounded by a conical surface (104) which substantially matches the planar surface (22) and the conical surface (24) of applanation tonometer head (20). Disposable protective cover (100) includes at least one tab member (130) for use in handling tonometer cover (100) during application and removal therefrom. Protective cover (100) in general and the planar surface (102) in particular must fit tightly to applanation head (20), be optically transparent, and sufficiently thin so as not to interfere with the tonometer measurement. Protective cover (100) is releasably secured to applanation head (20) by a double-backed removable adhesive strip (140) which is located on the conical surface (24) of applanation tonometer head (20).
    • 一种用于应用于Goldmann型压平眼压计(10)的压平眼压计头(20)的一次性保护罩(100)。 一次性保护盖(100)可以是类似轮廓的袋,或者优选地预先形成为截头圆锥形轮廓,其具有由基本上与平坦表面(22)匹配的锥形表面(104)界定的平坦表面(102) 压平眼压计头部(20)的锥形表面(24)。 一次性保护盖(100)包括至少一个突片构件(130),用于在施加和移除眼压计盖期间处理眼压计盖(100)。 通常,保护罩(100)和平坦表面(102)特别必须紧贴于压平头(20),光学透明并且足够薄以便不会干扰眼压计测量。 保护罩(100)通过位于压平眼压计头部(20)的锥形表面(24)上的双重可拆卸的粘合带(140)可释放地固定到压平头(20)。
