    • The invention provides a hypoallergenic disposable cover for the probe tip of a contact tonometer comprising a thin film having an ultimate elongation in the range of 500 to 1000%, a tensile strength in the range of 1000 to 5500 psi and a modulus of elasticity at 100% strain in the range of 50 to 2000 psi, whereby when installed onto the probe tip, the cover creates a barrier against microorganisms from the eye of a patient to said probe tip during a tonometric examination while allowing measurement of intraocular pressure through the disposable tip cover.
    • 本发明提供了一种用于接触眼压计的探针尖​​端的低变应原性一次性罩,其包括具有在500至1000%范围内的极限伸长率,1000至5500psi范围内的拉伸强度和100℃下的弹性模量的薄膜 %应变在50至2000psi的范围内,由此当安装到探针尖端时,盖在测量测量期间产生从患者的眼睛到所述探针尖端的微生物的屏障,同时允许通过一次性尖端测量眼内压 盖。
