Publication number: 20220313488Abstract: An apparatus, system and method of controlling the flow rate of an irrigation fluid. The apparatus, system and method include modifying a pressure gravitationally above the irrigation fluid in a fluid reservoir to increase the flow rate through a surgical pack by iteratively controlling infusion of gas to the fluid reservoir. The iteratively controlling comprises sensing an in-range response to said modifying, wherein the infusion of gas is enabled; and sensing an out-of-range response to said modifying. If, based on prior ones of said modifying: the out-of-range response poses no danger to a patient, the infusion of gas is enabled; the out-of-range response poses a substantial danger to the patient, the infusion of gas is disabled; or the out-of-range response poses no substantial danger to the patient, the iteratively controlling comprises applying a successive series of modifications to correct the out-of-range response.Type: ApplicationFiled: April 1, 2021Publication date: October 6, 2022Inventors: Abraham Hajishah, Edith Fung
