Abstract: An application system and an application method for applying a flexible protective cover (1) to the frustoconical tip (21) of an ophthalmological instrument part (2) are proposed. The protective cover (1) is arranged in the depression (31) of an applicator part (3) above a stamp (34) made of compressible material. The stamp (34) is attached to the base of the depression (31) and aligned towards the opening (32) of the depression (31). The tip (21) can be inserted into the protective cover (1) through the opening (32). During the inserting operation, a membrane (14) of the protective cover (1) comes into contact with the contact area (22) and is pressed against the stamp (34). The membrane (14) is pressed between the contact area (22) and the stamp (34) and air which is located between the membrane (14) and the contact area (22) is forced out.

Abstract: A flexible protective cover (1) for ophthalmological tonometers which have a contact area for placing on an eye and a method for producing the protective cover (1) in one piece are proposed. The protective cover (1) has a flexible membrane (14) with a membrane thickness of less than 55 ?m for covering the contact area. In the production of the protective cover (1), in a first step elastic material is injected into a cavity between an outer mould part and an inner mould part. In a second step, part of the protective cover (1) is formed as a membrane (14) for covering the contact area by the inner mould part and the outer mould part being moved towards each other in the region of the membrane (14) to be formed, so that a membrane (14) with a constant membrane thickness in the range from 30 ?m to 50 ?m is formed. The production method permits inexpensive production of flexible protective covers (1) in one piece with thin membranes (14) which do not impair eye-pressure measurements, or only slightly.
