Ophthalmic surgical cartridge

An ophthalmic surgical cartridge, comprising:

• at least one fluid pump having a pump chamber, a drive chamber, and a fluid-tight and ion-tight partition element with an edge,
• wherein the pump chamber defines a first volume and the drive chamber defines a second volume,
• wherein the drive chamber is separated from the pump chamber by the fluid-tight and ion-tight partition element,
• wherein the fluid-tight and ion-tight partition element defines a partition element center axis,
• wherein the fluid-tight and ion-tight partition element is connected on the edge to the at least one fluid pump such that the fluid-tight and ion-tight partition element and the edge are not displaceable in a direction running parallel to the partition element center axis,
• wherein a body fluid is suppliable to the pump chamber through a body fluid feed line, the body fluid being an irrigation fluid or an aspiration fluid,
• wherein a drive fluid that differs from the body fluid is suppliable to the drive chamber, a deformation or change in position of at least a portion of the fluid-tight and ion-tight partition element being achievable with the drive fluid, as a result of which the second volume can be made to increase in size and, at the same time, the first volume can be made to decrease in size, as a result of which the body fluid can be drained from the pump chamber through a body fluid discharge line,
• wherein the drive chamber has a front side wall defining a front side wall center axis running through a geometric center of the front side wall and perpendicular to the front side wall, the front side wall center axis running in a line with the partition element center axis, and
• wherein the front side wall has an edge zone in which only a single passage opening is provided, through which the drive fluid is suppliable into the drive chamber from outside of the drive chamber to fill the drive chamber with the drive fluid, and through which the drive fluid can be drained from the drive chamber to remove the drive fluid from the drive chamber.
