Ophthalmic pressure control system, a kit of parts and a method
The invention relates to an ophthalmic pressure control system, comprising: a pressure regulator having an input port and an output port, and an infusion line having a proximal end and a distal end, the proximal end being connected to the output port of the pressure regulator, and the distal end being detachably connected to an ophthalmic irrigation module. Further, the system includes a control unit driving the pressure regulator for controlling an infusion fluid pressure at a distal end of the ophthalmic irrigation module. The control unit is arranged for performing a fluid calibration process including a step of determining a fluid impedance of the ophthalmic irrigation module. The infusion line is associated with a kit of parts including a first and a second ophthalmic irrigation device, or the ophthalmic irrigation module is an ophthalmic irrigation device for surgical use.
1. A kit of parts comprising:
a first ophthalmic irrigation module implemented as a first ophthalmic irrigation device for surgical use;
a second ophthalmic irrigation module implemented as a second ophthalmic irrigation device for determining a fluid impedance of the ophthalmic irrigation module for calibration use, wherein the fluid impedances of the first and second ophthalmic irrigation devices are mutually related in a unique, known manner.
2. The kit of parts according to claim 1 , wherein the first ophthalmic irrigation device includes an actuator mechanism and wherein the second ophthalmic irrigation device is a passive device.
3. The kit of parts according to claim 1 , wherein the first ophthalmic irrigation device is identical to the second ophthalmic irrigation device.
4. The kit of parts according to claim 1 , wherein the first and second ophthalmic irrigation devices have the same fluid impedance.
