Abstract
Official abstract text for this publication.
In various embodiments, a flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. An engagement device, such as a clutch, may disengage the flow selector from a mechanical valve when the fluid flow control system enters a manual mode. When the system is in a manual mode, the engagement device may engage the flow selector with the mechanical valve, allowing the flow selector to directly control the flow rate of the fluid through the mechanical valve. Applications to gases and anesthesia delivery are disclosed herein. Various alternative components and embodiments are described herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluid flow control system, comprising: a mechanical flow control valve configured to selectively receive a first fluid from a first fluid supply; an electronic flow control valve configured to selectively receive the first fluid from the first fluid supply; a diversion valve system configured to: prevent the flow of the first fluid to the mechanical flow control valve and allow the flow of the first fluid to the electronic flow control valve when the…
