Patent number: 10065007Abstract: In a method and breathing apparatus for providing support ventilation to a spontaneously breathing patient a pressure and/or a flow is monitored based on pressure and/or flow measurements, and efforts to inhale or exhale by the patient are detected based on changes in the monitored pressure and/or flow. When a change in the monitored pressure and/or flow indicating an effort to inhale or exhale is detected, the rate of that change is determined and used to calculate a suitable rate of change of pressure applied to the airways of the patient. By changing the applied pressure in accordance with the so determined suitable rate of change, the pressure rise time during inspiration and/or the pressure fall time during expiration can be adjusted to the needs of the patient to ensure efficient and comfortable ventilation.Type: GrantFiled: March 18, 2011Date of Patent: September 4, 2018Assignee: Maquet Critical Care ABInventors: Carl-Erik Troili, Mia Sköld

Patent number: 9974911Abstract: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11).

Patent number: 9656034Abstract: A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.Type: GrantFiled: January 23, 2013Date of Patent: May 23, 2017Assignee: RIC INVESTMETNS, LLCInventors: Jeffrey Kepler, Michael E. Mort, Richard A. Seman, Mark William DiMatteo, Christopher J. McCracken, James S. Vreelan, Steven B. Radney, Michael Bobeck, Allen Cameron, David P. Chastain, Patrick F. McDermott, William J.

Patent number: 9643019Abstract: A system for providing alerts of neurological events occurring in a human subject is provided. The system includes: a monitoring module adapted to detect and sample a neurological signal; an event detection module coupled to the monitoring module for detecting one or more types of predetermined reportable events based on the detected neurological signal; and an alert module coupled to the event detection module, wherein upon the detection of a reportable event by the event detection module, said alert module selects a first alert contact from a plurality of contacts contained in a contact list, and generates a first alert communication to the first alert contact.Type: GrantFiled: February 14, 2011Date of Patent: May 9, 2017Assignee: CYBERONICS, INC.Inventors: Jason A. Higgins, Michael Bland, Kent W. Leyde, W. Douglas Sheffield, John F. Harris, David M. Himes

Patent number: 9629971Abstract: The systems and methods include controlling pressure and/or flow during exhalation. The systems and methods include novel exhalation for ventilating a patient. The systems and methods decrease the amount of time it takes the patient to passively expire an inspired volume of gas. For example, the systems and method may determine one or more pressure profiles based on one or more criterion and may select and utilize the pressure profile that provides for the fastest rate of lung emptying.Type: GrantFiled: April 29, 2011Date of Patent: April 25, 2017Assignee: COVIDIEN LPInventors: Milenko Masic, Peter Doyle, Gardner Kimm

Patent number: 9616192Abstract: A breathable gas inlet control device permits flow regulation at the inlet of a flow generator for a respiratory treatment apparatus such as a ventilator or continuous positive airway pressure device. The device may implement a variable inlet aperture size based on flow conditions. In one embodiment, an inlet flow seal opens or closes the inlet to a blower in accordance with changes in pressure within a seal activation chamber near the seal. The seal may be formed by a flexible membrane. A controller selectively changes the pressure of the seal activation chamber by controlling a set of one or more flow control valves to selectively stop forward flow, prevent back flow or lock open the seal to permit either back flow or forward flow. The controller may set the flow control valves as a function of detected respiratory conditions based on data from pressure and/or flow sensors.Type: GrantFiled: March 25, 2011Date of Patent: April 11, 2017Assignee: ResMed Paris SASInventors: Philippe Auguste Chalvignac, Arthur Kin-Wai Yee, David Creusot, Enrico Brambilla

Patent number: 9606644Abstract: The invention relates to a manually operable input device (1) having a sensor system (15) that comprises at least one rotary control knob (4) for detecting at least one movement characteristic variable. By predefining various movement patterns at the rotary control knob (4), various control commands can be generated. For this purpose, the input device (1) according to the invention comprises an evaluation unit (8) that compares the signal (13, 14) generated by the sensor system (15) with predefined rotational movement codes (C1-C16) and generates a code-dependent control command (16) if the predefined movement pattern or the corresponding signal (13, 14) matches a predefined rotational movement code (C1-C16).Type: GrantFiled: February 17, 2014Date of Patent: March 28, 2017Assignee: GOMTECH GMBHInventors: Bernd Gombert, Friedemann Seebass

Patent number: 9590624Abstract: An input apparatus capable of preventing a user's unintentional input by notifying the user of a change in a pressure load is provided. The input apparatus has a touch face configured to receive a touch operation, a load detection unit configured to detect a pressure load of the touch operation to the touch panel, a vibration unit configured to vibrate the touch face, and a control unit, when the load detection unit detects a pressure load satisfying a standard load to receive an input, configured to perform a control to receive the input by the touch operation. When the load detection unit detects a pressure load satisfying a standard load, lower than the standard load to receive an input, the control unit controls the vibration unit to vibrate.Type: GrantFiled: July 28, 2010Date of Patent: March 7, 2017Assignee: KYOCERA CorporationInventors: Junichi Ujii, Megumi Kuwabara
