Problems solved by technology

However, specific conditions that arise during ophthalmic surgery require the system to operate quickly and efficiently, which can be difficult to perform manually
For example, if the suction system encounters a substance or obstruction that cannot be removed (eg, a non-fluid substance or a dense substance), the obstruction often causes the suction system to lose proper suction

Abstract

Ocular fluid management systems and methods of operating the same. One ocular fluid management system includes a chamber, a diaphragm, a sensor, and a controller. The chamber includes a first portion and a second portion. The first portion is connected to an input line for receiving fluids into the first portion and an output line for discharging fluids from the first portion. The diaphragm is contained in the chamber and changes position based on a pressure difference between the first and second portions. The sensor detects a position of the diaphragm and transmits a signal based on the detected position. The controller is configured to receive the signal and control operation of at least one of a peristaltic pump and a vacuum pump based on the signal to maintain the diaphragm in a predetermined position.

Description

technical field [0001] Embodiments of the invention relate to ocular fluid management systems. More specifically, embodiments of the invention relate to a fluid management system that senses the position of a diaphragm and operates in one or more modes of operation. Background technique [0002] Fluid management systems, such as aspiration systems and infusion systems, are commonly used during ophthalmic surgery. The suction system removes fluid from the patient's eye. In contrast, infusion systems deliver fluid to a patient's eye. An integrated fluid management system provides both aspiration and infusion functions under common control. The operator can control the amount of pressure or suction applied by each system using foot pedals, control panel settings, or a combination of both. However, certain conditions that arise during ophthalmic surgery require the system to operate quickly and efficiently, which can be difficult to perform manually. For example, if the suc...
