Patent number: 9333312Abstract: A breathing apparatus has an expiratory flow sensor unit, an expiratory pressure sensor unit, an expiratory pressure regulator, and an expiratory control unit operatively connected to the expiratory pressure sensor unit for a feedback control of an expiratory pressure during an expiratory phase of a breathing cycle. The expiratory control unit is adapted to provide a real time target pressure value during the expiratory phase to the expiratory pressure regulator for adjusting a desired positive end expiratory pressure (PEEP) level (PEEPset) based on an inspiratory tidal volume of an inspiratory phase of the same breathing cycle and a currently accumulated expiratory tidal volume measured by the expiratory flow sensor unit. In this manner advantageous regulation of PEEP with minimized work of breathing is obtained.Type: GrantFiled: March 27, 2009Date of Patent: May 10, 2016Assignee: Maquet Critical Care ABInventors: Erik Cardelius, Mathias Eklund

Patent number: 9295796Abstract: A breathing system for ventilating a patient has a gas channel enclosing a gas channel volume (V), and a compliance (C). The system has a flow calculation unit operative to determine a gas flow estimate (Fe) at a flow estimate location in the gas channel. The gas flow estimate (Fe) is based on a relationship between a monitored gas flow (Fm) in the gas channel and a compressible gas flow (Fc) which depends on the compliance (C) in the gas channel. The monitored gas flow (Fm) is a gas flow at a monitoring location in the gas channel and the compressible gas flow (Fc) is a flow of gas in the gas channel between the flow estimate location and the monitoring location, and the flow estimate location is remote from the monitoring location.Type: GrantFiled: May 22, 2010Date of Patent: March 29, 2016Assignee: Maquet Critical Care ABInventors: Mathias Eklund, Fredrik Norrby, Magnus Hallbäck

Patent number: 9273987Abstract: According to the present invention a flow meter is provided for measuring a fluid, comprising a measuring tube with a measuring piston movably arranged in said measuring tube, and elements for changing the direction of movement of the measuring piston in said measuring tube, wherein said measuring piston, when measuring, is designed to be moved in said measuring tube under the influence of said fluid. Sensor elements detect movement of the piston and the direction of movement in said measuring tube, and sensor elements detect when the piston is situated in at least one of its reversing areas before the measuring piston has reached the extreme point of the reversing area, so as to afford a substantially continuous flow detection for said fluid.Type: GrantFiled: February 23, 2012Date of Patent: March 1, 2016Assignee: EC Instruments ABInventors: Erik Cardelius, Mathias Eklund
