Fluid management system for use in a medical procedure
First Claim
1. A method for controlling fluid flow provided by an apparatus to a patient'"'"'s eye during a surgical procedure, comprising:
- automatically adjusting an irrigation fluid source to a predetermined height during the surgical procedure;
receiving a request that the irrigation fluid source be moved to a different height from the predetermined height; and
on a condition that the different height is determined to be inappropriate;
ceasing the automatic adjusting of the irrigation fluid source at the predetermined height while the fluid continues to flow to the patient'"'"'s eye,preventing further automatic adjusting of the irrigation fluid source away from the predetermined height, andallowing only manual adjustment of the irrigation fluid source height to adjust the flow rate of said fluid which continues to flow to the patient'"'"'s eye, until the surgical procedure is completed or until an indication to resume automatic height adjustment of the irrigation fluid source is received.

Abstract
An apparatus and method for controlling fluid flow provided by an apparatus to a patient'"'"'s eye during a surgical procedure. The method includes automatically adjusting an irrigation fluid source to a predetermined height during the surgical procedure using the apparatus, receiving a request either that the irrigation fluid source be moved to a different height from the predetermined height or that a manual adjustment mode be entered, and ceasing automatic adjusting and requiring manual adjustment of the height of the irrigation fluid source until the surgical procedure is completed or an indication received to resume automatic height adjustment of the irrigation fluid source. As an alternative, fluid flow rate or intraocular pressure may be maintained, and the design may include making adjustments to default values in other modes based on the adjustment made.

12. An apparatus configured to provide fluid from an irrigation fluid source during a surgical procedure, comprising:
-
a retractable tubular arrangement configured to maintain the irrigation fluid source at a desired height; a controller configured to automatically adjust the irrigation fluid source using the retractable tubular arrangement to a predetermined height during the surgical procedure; and a processor configured to receive a request that the irrigation fluid source be moved to a different height from the predetermined height and on a condition that it is determined that the different height is inappropriate, the processor further configured to command the controller to; cease the automatic adjusting of the irrigation fluid source at the predetermined height while the fluid continues to flow during the surgical procedure, prevent further automatic adjusting of the irrigation fluid source away from the predetermined height, and allow only manual adjustment of the irrigation fluid source height to adjust the flow rate of said fluid which continues to flow during the surgical procedure, until the surgical procedure is completed or until an indication is received to resume automatic adjustment of height of the irrigation fluid source. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for controlling fluid flow to a patient'"'"'s eye using an ocular surgical device during an ocular surgical procedure, comprising:
-
automatically positioning an irrigation fluid source at a first desired height via the ocular surgical device without operator intervention during the ocular surgical procedure; requesting the ocular surgical device move the irrigation fluid source to a different height from the first desired height; and on a condition that the different height is determined to be inappropriate; ceasing the automatic positioning of the irrigation fluid source without operator intervention at the predetermined height while the fluid continues to flow to the patient'"'"'s eye, preventing further automatic adjusting of the irrigation fluid source away from the predetermined height, and allowing only manual adjustment of the irrigation fluid source height to adjust the flow rate of said fluid which continues to flow to the patient'"'"'s eye, until the surgical procedure is completed or until an indication is received to resume automatic height adjustment without operator intervention of the irrigation fluid source. - View Dependent Claims (20, 21, 22, 23, 24, 25)
