摘要： An ophthalmic surgical cartridge has a fluid pump with a pump chamber and a drive chamber which are separated by a fluid-tight and ion-tight partition element. A body fluid is suppliable to the pump chamber and a drive fluid is suppliable to the drive chamber. A deformation or change in position of a portion of the partition element is achievable with the drive fluid which increases the second volume in size and decreases the first volume in size to drain the body fluid from the pump chamber. The drive chamber has a front side wall with an edge zone in which only a single passage opening is provided, through which the drive fluid is suppliable into the drive chamber to fill the drive chamber with the drive fluid, and through which said drive fluid can be drained from the drive chamber to remove the drive fluid from the drive chamber.

摘要： A cassette for a console of an ophthalmosurgical system for treating an eye is configured for insertion into a cassette receiving region of the console and has a fluid pump configured to deliver a treatment fluid, a tube for attachment to a handpiece, and a connection unit secured against detachment, of a cassette-side end of the tube to a cassette housing of the cassette. The connection unit includes an attachment stub arranged on the cassette housing and has a through opening for the treatment fluid, and a plug-in connector arranged on the cassette-side end of the tube and likewise has a through opening for the treatment fluid, with the plug-in connector, when it is connected to the attachment stub, being held in a fluid-tight manner with respect to the attachment stub and so as to be able to rotate about a longitudinal axis of the through opening.

摘要： A tube for a medical treatment system has a first channel for feeding an irrigation fluid from a console of the system to a medical treatment instrument of the system and a second channel for discharging an aspiration fluid from the instrument to the console. The first and the second channels are arranged in parallel. The first channel has a first wall and the second channel has a second wall. A second material of the second wall has a greater hardness than a first material of the first wall. The tube is formed from two individual tube elements for the channels. The tube elements are welded or adhesively bonded in a connection region. The difference between the hardness of the first material and the hardness of the second material is at least 10 ShA and at most 15 ShA.
