Patent number: 8997784Abstract: 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.Type: GrantFiled: November 14, 2012Date of Patent: April 7, 2015Assignee: Shenzhen Mindray Bio-Medical Electronics Co. Ltd.Inventors: Richard G. Cipolli, David Gibson

Patent number: 8215338Abstract: The method for controlling the progression of a fluid, from upstream to downstream, in a microfluidic component comprising for example a plurality of microchannels each comprising a plurality of successive reaction or detection zones and a plurality of passive valves, controls the progression of the fluid in the microchannels by controlling the increase of a pressure difference between upstream and downstream of the component. The method controls the pressure difference increase discontinuously in the form of enabling pulses so as in particular to synchronize passing of the corresponding passive valves of the microchannels. The pressure difference is advantageously adjusted to a zero value between two successive enabling pulses.Type: GrantFiled: February 15, 2007Date of Patent: July 10, 2012Assignees: Commissariat a l'Energie Atomique, Bio MerieuxInventors: Cyril Delattre, Raymond Charles, Patrick Pouteau

Publication number: 20110132480Abstract: A fluid flow regulator (1) of the passive type is disclosed which has a fluid inlet adapted to be connected to a fluid reservoir and a fluid outlet (13) adapted to be connected to a patient's body. The regulator comprises a rigid substrate (2) and a resilient membrane (3) tightly linked together so as to define a cavity (6) there between which is disconnected to the fluid outlet while the membrane has a first surface (12) opposite the cavity which is connected to the fluid inlet. The membrane has a plurality of through holes (15) contiguous with the cavity, to define a pathway for a fluid from the fluid inlet to the fluid outlet, and is flexible so as to be able to come into contact with the substrate as a fluid applies a sufficient pressure on the first surface.Type: ApplicationFiled: June 26, 2009Publication date: June 9, 2011Inventor: Eric Chappel

Patent number: 6997202Abstract: A gas supply system arranged for dispensing of gas at a predetermined flow rate. The system employs a gas dispensing flow circuitry arranged for dispensing gas at selectively variable gas flow conductance conditions, to maintain the flow rate of the dispensed gas at a predetermined, e.g., constant, value in the operation of the system. The gas dispensing flow circuitry may include an array of dispensed gas flow passages, each of a differing conductance, or alternatively a variable conductance gas flow passage equipped with a variable conductance assembly for modulating the gas flow conductance of the passage, in response to sensed pressure of the gas or other system parameter. The system permits the flow rate of a dispensed gas to be maintained at a consistent desired level, despite the progressive decline in source gas pressure as the gas source vessel is depleted in use.Type: GrantFiled: December 17, 2002Date of Patent: February 14, 2006Assignee: Advanced Technology Materials, Inc.Inventor: W.
