The invention relates to a replaceable cartridge () for an ophthalmological apparatus (), comprising at least one hard region as a housing and at least one soft region, the hard region and the soft region forming inner liquid channels of the replacement cartridge (). The soft region embodies functional elements of the replacement cartridge (), said functional elements comprising at least one pump device for pumping liquid into the liquid channels, a valve device for modifying a through-flow cross-section in at least one of the liquid channels, and a pressure-detecting device for determining a liquid pressure in at least one of the liquid channels. The pressure-detecting device comprises a pressure chamber which is connected to one of the liquid channels, and a flexible membrane which peripherally surrounds a coupling element. The coupling element is designed with a recess such that a fork-shaped arm of a force-measuring device, which is oriented substantially parallel to the membrane, can be inserted into the recess in such a way that the coupling element has at least two sides, and with the arm, a force effect occurring in a substantially normal direction in relation to the membrane can be detected on the membrane.

Replacement part for ophthalmological apparatus

The invention relates to a dosing system for an inhalation device which is capable of aliquoting a precise and accurately metered volume from a larger pre-defined fill volume. The dosing system comprises a filling chamber for receiving a liquid to be aerosolized, the filling chamber having a lateral wall, an inlet opening and an outlet opening with a closing means () for closing the outlet opening. The dosing system further comprises an overflow chamber surrounding the inlet opening of the filling chamber and a plunger which can be inserted, at least partially, into the filling chamber, and which sealingly contacts the lateral wall such as to displace liquid from said filling chamber upon insertion, and push a metered volume of the liquid out from the filling chamber through the outlet opening and feed it to the nebulizing means of the inhalation device.
