Abstract
A system and method are provided for oxygenating infusion/irrigation fluid, and for providing the hyperoxic infusion/irrigation fluid so formed to an ophthalmic surgical site.
Claims25
A system for oxygenating infusion/irrigation fluid during the course of ophthalmic surgical procedures comprising:
- a source of oxygen gas;
- a source of infusion/irrigation fluid;
- delivery apparatus for delivery of infusion/irrigation fluid from the infusion/irrigation fluid source to an ophthalmic surgical site;
- and
- gas permeable apparatus connected to said source of pressurized oxygen gas and to the delivery apparatus for oxygenating said infusion/irrigation fluid substantially immediately prior to the delivery of the infusion/irrigation fluid to the ophthalmic surgical site.
A system for oxygenating infusion or irrigation fluid during the course of an ophthalmic surgical procedure, the system comprising:
- a source of infusion/irrigation fluid;
- delivery apparatus for delivery of infusion/irrigation fluid from the infusion/irrigation fluid source to an ophthalmic surgical site;
- and
- oxygen gas in fluid communication with the infusion/irrigation fluid for oxygenating the infusion/irrigation fluid prior to the delivery of the infusion/irrigation fluid to an ophthalmic surgical site.
A method for oxygenating fluid for delivery to an opthalmic surgical site, comprising:
- providing a system for oxygenating fluid during the course of ophthalmic surgical procedures;
- oxygenating fluid for delivery to an ophathalmic surgical site prior to the delivery of the infusion/irrigation fluid to the ophthalmic surgical site.
The method of claim 15 wherein the fluid is oxygenated by gas diffusion.
A method for oxygenating fluid for delivery to a surgical site, comprising:
- providing a system for oxygenating fluid during the course of a surgical procedure;
- oxygenating fluid for delivery to the surgical site prior to the delivery of the fluid to the surgical site.
A method for oxygenating infusion/irrigation fluid for delivery to a surgical site, comprising:
- (a) providing a system for oxygenating infusion/irrigation fluid during the course of ophthalmic surgical procedures comprising:
- a source of oxygen gas;
- a source of infusion/irrigation fluid;
- delivery apparatus for the controlled delivery of infusion/irrigation fluid from said infusion/irrigation fluid source to an ophthalmic surgical site;
- and
- gas permeable apparatus connected to the source of oxygen gas and to the delivery apparatus;
- and
- (b) oxygenating said infusion/irrigation fluid immediately prior to the delivery of the infusion/irrigation fluid to the ophthalmic surgical site.
