INFUSION SYSTEM
Developed to maintain the IOP
An important criterion for eye surgery is maintenance of the intraocular pressure (IOP) to ensure a stable anterior chamber and a stable eye. To maintain the IOP, the OS 4 has two options for infusion systems: active infusion and gravity infusion *.
Active infusion
The gas-driven active infusion is available on the OS 4 and Faros devices. The OS 4 offers active infusion for procedures in the anterior and posterior segments. In the case of bleeding or other situations requiring high pressure, the active infusion can react quickly and reach a pressure of up to 120 mmHg. The active infusion is independent of the room height as the BSS bottle is suspended from a fixed hook. It is connected to the compressed air outlet (GFI = Gas Forced Infusion) via a Luer lock connection, whereby the connection is colour-coded to avoid installation errors.
Gravity infusion
Gravity infusion on the Faros and the OS 4 is mechanically driven. Like active infusion, gravity infusion is also responsible for maintaining the IOP during surgery. The pressure can be maintained at up to 100 mmHg or 135 cm and the setting values can be selected on the surgical device *. The tubing set is included in most phaco and vitrectomy packs from Oertli which makes gravity infusion an economical solution.
New function: Quick setting of the infusion values
The settings for the infusion values can be quickly changed using the foot pedal in five-unit increments (mmHg or cm) *.
Developed to maintain the IOP
To maintain a stable IOP during a surgical intervention, different systems have to work together effectively. Our active infusion or gravity infusion combined with our phaco or vitrectomy instruments form a closed and coordinated system that helps to maintain the intraocular pressure.
Choose your preferred infusion system
Gravity infusion
- Available for the OS 4, Faros and CataRhex 3
- Mechanical driven (OS 4 and Faros)
- Developed to maintain the IOP for a stable anterior chamber *
- Pressure up to 100 mmHg / 135 cm
(depending on the height of the patient's eye above the floor) - Economic solution as part of the phaco and vitrectomy packs
- Controllable in cm or mmHg
Fast reaction time with active infusion
Comparison of active infusion with gravity infusion at the same pressure level before and after the pressure change.
The maximum IOP is reached quicker with the active infusion than with the gravity infusion.
Pressure comparison active and gravity infusion
Comparison of active infusion with gravity infusion in terms of achievable IOP.
A pressure of up to 120 mmHg can be achieved with the active infusion set. When the IV pole of the OS 4 is fully extended, an IOP of 95 mmHg can be achieved with gravity infusion. This therefore allows a higher pressure to be achieved with active infusion.
