Publication number: 20130327331Abstract: The ventilation module (8) regulates the inspiratory pressure (P) according to an inspiratory pressure order (AI). A control module (9) compares the breathed volume at each cycle (VTI) with a minimum volume order (VRImini) and varies the pressure order (AI) in the direction tending to maintain the breathed volume (VTI) just over the minimum (VTImini), but keeping the pressure order (AI) within the interval comprised between the two extreme values (AImini, AImaxi). Utilization to combine the advantages of the pressure mode ventilation with those of the volumetric ventilation.Type: ApplicationFiled: August 14, 2013Publication date: December 12, 2013Applicant: Covidien LPInventor: Guy Bourdon

Patent number: 5664562Abstract: A patient circuit (1) comprises an inspiratory branch (3) connected to an inspiratory flow rate source (11), and an expiratory branch (4) connected to the atmosphere through an expiratory valve (V.sub.E). An inspiratory valve (V.sub.I) is arranged between the inspiratory flow rate source (11) and the inspiratory branch (3). During inspiration, the inspiration valve (V.sub.I) is open and the pressure of the inspiratory flow source is applied to the expiration valve (V.sub.I) to close the latter. During expiration, the inspiration valve (V.sub.I) is closed, and the control inlet (6) for controlling the expiration valve (V.sub.I) is connected through a control valve (VC1) to a low pressure source (14) adjustable in a range including the zero value. The patient breathes as desired under atmospheric pressure or under positive expiratory pressure. Utilization for making a simple apparatus which provides for multiple adjustments, and compatible with its utilization at home.Type: GrantFiled: March 13, 1995Date of Patent: September 9, 1997Assignee: Pierre Medical S.A.Inventor: Guy Bourdon

Patent number: 4811755Abstract: The valve comprises a movable closure member and a seat in which the closure member is displaced relative to the seat for varying the gas flow through the valve. According to the invention, the process comprises causing the displacement of the movable closure member by means of a step-by-step motor as a function of the variation of the flow produced by each step according to the geometry of the valve, the type of flow employed and the pressure of the gas on the upstream and/or downstream side of the valve, and then producing a corresponding control signal for displacing in the desired direction the motor through the number of steps corresponding to the calculated flow, the displacement of the motor causing the correlative displacement of the movable closure member.Type: GrantFiled: December 11, 1987Date of Patent: March 14, 1989Assignee: L'Air LiquideInventors: Guy Bourdon, Dominique Lampin, Daniel Leclerc

Patent number: 4381556Abstract: There is disclosed a device for displacing a video disk with respect to a reading head which includes the driving of a conductive disk by means of a video disk rotational motor. The conductive disk passes through the air gaps of two electromagnets located on either side of the displacement axis of a movable member supporting the rotational motor. By differentially energizing the electromagnets, a force is produced which provides for forward and backward movement of the complete movable member of the reader.Type: GrantFiled: December 3, 1980Date of Patent: April 26, 1983Assignee: Thomson-CSFInventors: Guy Bourdon, Jean-Claude Lehureau
