OPHTHALMIC SURGICAL CASSETTE

摘要

An ophthalmic surgical cassette acts with a peristaltic pump having a wheel defining a periphery and includes a cassette body having a first recess which, in cross section, has a circle segment shape defining a circular arc. The first recess permits the wheel of the peristaltic pump to engage therein. An aspiration line transports aspirated fluid via the pump. A second recess along the circular arc of the circle segment shape has a wall forming a fluid channel. The fluid channel has a first end connected to the aspiration line and a second end connected to a collection container supply line. An elastic cover covers the channel and is held to ensure a constant spacing of the cover to the second recess to permit fluid from the aspiration line to be transported through the channel to the container supply line via the wheel acting on the cover.

主权项

1. An ophthalmic surgical cassette configured to act with a peristaltic pump having a wheel defining a periphery, the ophthalmic surgical cassette comprising:
a cassette body having a narrow side defining a first recess which, in cross section, has a circle segment shape defining a circular arc; said first recess being configured so as to permit the periphery of the wheel of the peristaltic pump to engage therein; an aspiration line configured to transport a fluid aspirated via the peristaltic pump; said cassette body defining a second recess along said circular arc of said circle segment shape; said second recess having a wall forming a fluid channel in radial direction; a collection container supply line; said fluid channel having a first end connected to said aspiration line and a second end connected to said collection container supply line; an elastic cover configured to cover said fluid channel; and, a holding arrangement for holding said elastic cover to ensure a constant distance of said cover to said second recess so as to permit fluid from said aspiration line to be transported through said covered fluid channel to said collection container supply line via the wheel of the peristaltic pump acting on said cover.
