DIAPHRAGM-POSITION-CONTROLLED, MULTI-MODE OCULAR FLUID MANAGEMENT SYSTEM AND METHOD

摘要

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.

1. An ocular fluid management system, comprising:
a chamber including a first portion and a second portion, the first portion connected to an input line configured to receive fluids into the first portion of the chamber and an output line configured to discharge fluids from the first portion of the chamber; a pump communicating with at least one selected from the group including the input line and the output line; a pressure regulator communicating with the second portion of the chamber; a diaphragm contained in the chamber and configured to change position based on a pressure difference between the first portion and the second portion of the chamber; a sensor for detecting a position of the diaphragm and transmitting a signal based on the detected position; and a controller configured to receive the signal and control operation of at least one of the pump and the pressure regulator based on the signal to maintain the diaphragm in a predetermined position.
