Publication number: 20140261410Abstract: This disclosure describes systems and methods for providing novel back-up ventilation that allows the patient to trigger or initiate the delivery of breath. Further, this disclosure describes systems and methods for triggering ventilation when base flow and/or inspiratory flow is unknown or indeterminable by the ventilator.Type: ApplicationFiled: March 13, 2013Publication date: September 18, 2014Applicant: Covidien LPInventors: Gabriel Sanchez, Nancy F.

Publication number: 20140251327Abstract: A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.Type: ApplicationFiled: May 22, 2014Publication date: September 11, 2014Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: William A.

Patent number: 8821621Abstract: A filter system includes a housing, a filter medium disposed within the housing and a optical analyte sensor also disposed within the housing in fluid communication with the filter medium. The optical analyte sensor includes a detection medium that changes at least one of its optical characteristics in response to an analyte. The filter system further includes an optical reader having at least one light source and at least one detector. The optical reader is attached to the housing such that at least a portion of light emitted by at least one light source is reflected from the optical analyte sensor and captured by at least one detector.Type: GrantFiled: March 29, 2011Date of Patent: September 2, 2014Assignee: 3M Innovative Properties CompanyInventors: Gary E. Dwyer, Thomas W. Holmquist-Brown, Kiran S. Kanukurthy, Neal A. Rakow

Publication number: 20140216451Abstract: Gas-pressure-based testing, in some embodiments, features a self-leak-testing module (120) that includes an internal sensor and is configured for measuring, using the sensor, gas leakage (179, 180) from a set of walls that defines respective gas passageways that both exist within the module and are incident to the gas pressure measured. One or more walls of the set may extend outside the module. The module can be configured for deciding, based on a result of the measuring, whether a magnitude of the leakage exceeds a predetermined threshold. A source for applying the pressure may be internal (138) or external (104, 132, 135). Gas pressure based pattern recognition can be used to identify, optionally during treatment and in real time, one or more leak sites responsible for the leakage. The module is implementable as a ventilation monitoring module that measures differential flow of a breathing circuit, the testing serving to prevent cross-contamination of patients.Type: ApplicationFiled: September 10, 2012Publication date: August 7, 2014Applicant: KONINKLIJKE PHILIPS N.V.Inventors: Michael Brian Jaffe, Joseph Allen Orr

Patent number: 8783247Abstract: A respiratory circuit apparatus and circuit are provided. The circuit includes: an adapter having a plurality of connectors of two or more different internal or outer diameters; and a pressure release valve configured to emanate sound if a pressure of a gas received at the pressure release valve is greater than or equal to an activation pressure of the pressure release valve. The pressure release valve can have a first end of a body portion coupled with one of the plurality of connectors of the adapter. The pressure release valve can be coupled inline in the respiratory circuit via the adapter and in close proximity to a patient location.Type: GrantFiled: February 4, 2010Date of Patent: July 22, 2014Assignee: Wet Nose Technologies, LLC.Inventor: Lionel Newman, Jr.

Publication number: 20140190479Abstract: A speaking valve includes a hollow body configured to be secured to a connector of a tracheostomy system disposed in a patient. The speaking valve further includes a cap that houses a valve member, which enables the speaking valve to act as a one-way check valve. The valve member, hollow body, or other components of the valve may include a material that undergoes a chemical changed when exposed to moisture, i.e., a hydrosensitive material. Particularly, the hydrosensitive material may exhibit a color change when exposed to moisture. As such, the hydrosensitive material may be useful in providing a visual indication of the saturation and/or moisture level of the speaking valve.Type: ApplicationFiled: January 10, 2013Publication date: July 10, 2014Applicant: NELLCOR PURITAN BENNETT LLCInventors: Kamlesh Sethiya, Emmet Bolger

Patent number: 8763603Abstract: The invention discloses devices and methods for identifying a diver in distress and initiating a rescue response. Specifically, embodiments of the present invention allow for identification of a diver who is not breathing properly and in response giving local stimuli to allow the diver to response. Should he/she not respond, the instant invention will initiate steps to bring the diver back to the water surface and alert others as to his/her need of assistance.Type: GrantFiled: June 1, 2010Date of Patent: July 1, 2014Inventor: Netanel Raisch
