1. A pressurized infusion device for an ophthalmic surgical machine, the pressurized infusion device comprising:
- a flexible band having first and second ends;
a curved base;
a bag containing irrigating fluid, the bag located between the flexible band and the curved base;
an irrigation line coupled to the bag;
a pressure sensor for reading pressure in the irrigation line;
a motor coupled to a shaft, the second end of the band coupled to the shaft;
a spring coupled to the shaft, the spring providing a torque on the shaft; and
a controller, the controller receiving an input from the irrigation pressure sensor to control the motor;
wherein when the motor is actuated to turn the shaft, tension is produced in the band to change pressure in the bag.

Abstract
A pressurized infusion device has a flexible band with first and second ends, a curved base, and a bag containing fluid. The bag is located between the flexible band and the curved base. The second end of the flexible band is coupled to a shaft. A motor is also coupled to the shaft. The motor is actuated to turn the shaft and produce tension in the band thereby changing the fluid pressure in the bag.
