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.

A syringe includes a hollow body, a piston and a seal. The hollow body has a surrounding hollow body surface and forms a passage therein. An axis is formed in an axial longitudinal direction of the hollow body and the passage has a rear body opening and a front body opening arranged opposite to one another in the longitudinal direction. A first needle seat is formed at the front body opening, in which a needle cannula is arranged and relative to which the needle cannula is movable along the axis. The piston is arranged in the hollow body and is movable in the passage along the axis. The seal is able to be cancelled such that a receiving chamber and a supply space of the syringe are in flow communication in a release position.

Syringe

A syringe for multi-component materials includes a mixer housing, a mixing element, a multi-component cartridge and a mixing head, the mixing head being arranged at least partly within the mixer housing and adjacent to the multi-component cartridge. The mixing head is arranged moveable in an axial direction of the syringe between at least two positions, the at least two positions including a sealed position and a dispensing position. The axial movement of the mixing head is brought about by rotation of at least a part of the mixer housing relative to the multi-component cartridge. The mixing head is axially displaced in a direction opposite to a dispensing direction on a displacement of the mixing head from the sealed position into the dispensing position.

A dispensing apparatus includes a body, two inlets for flowable masses and two outlets through which the flowable masses can be dispensed, with one inlet being connected to one outlet and the other inlet being connected to the other outlet through the body. The two inlets are spaced apart from one another by a first spacing and the two outlets are spaced apart from one another by a second spacing, and with the second spacing being larger than the first spacing. A connection ring engages the body and is pre-mounted to the body. The dispensing apparatus is configured to be non-releasably connected to a two-component cartridge via the connection ring for the supply of the flowable masses to the inlets.
