| 20090314294 | Breathing assistance device comprising a gas regulating valve and associated breathing assistance method - The invention relates to a breathing assistance device for a patient, the device including: a source of respiratory pressurised gas; a gas transmission duct comprising a distal end coupled to said source and a proximal end coupled to the patient; a gas regulating valve interposed in the gas transmission duct at a proximal location, comprising a leakage orifice and an obstruction means capable of varying the opening of the leakage orifice upon signal of controlling means and allowing a bidirectional gas flow through the leakage orifice in both expiration and inspiration phases. | 12-24-2009 |
| 20100018529 | Breathing assistance device comprising a gas regulating valve and associated breathing assistance method - The invention relates to a breathing assistance device for a patient (P), the device including: —a source of respiratory pressurised gas (S), a gas transmission duct ( | 01-28-2010 |
| 20110132363 | BREATHING ASSISTANCE APPARATUS - A breathing assistance apparatus operates in alternating inhalation and expiratory phases wherein a) the control means of the apparatus comprise selection means capable of selecting a pressure parameter or a flow rate parameter to define; b) the reference value for the gas source, the selection means are controlled by an automatic control unit being: I) connected to pressure and flow rate sensors situated on the inhalation duct to form a direct closed regulation loop for selecting a reference value parameter, II) associated to a program allowing the selection to be made in real time from a pressure or flow rate signal, so that the association of a direct closed regulation circuit for the selection of a reference value parameter with a valve permitting proportional operation, allows real time control of barometric and volumetric operating modes, between and during the inhalation and expiratory phases. The invention also concerns associated operating processes. | 06-09-2011 |
| 20110139153 | BREATHING ASSISTANCE DEVICE WITH SEVERAL SECURE RESPIRATOR MODES AND ASSOCIATED METHOD - A breathing assistance device, capable of operating according to several respiratory modes forming a list of possible modes. The device is equipped with a mechanism for selecting a desired mode from a group of modes that can be selected. The device also includes a mechanism for realizing a configuration diagnostic of the device, a mechanism for associating with authorization level with each possible mode, according to the results of the diagnostic, with the lowest authorization level corresponding to unauthorized modes, a mechanism for authorizing only the selection of authorized modes, in such a way that selecting unauthorized modes is impossible. | 06-16-2011 |
| 20120012109 | BREATHING ASSISTANCE DEVICE - The present invention proposes a breathing assistance device for a patient, comprising:
