The user interface includes a graphic representation of a breath cycle that displays the breath cycle currently being ventilated, and is also responsive to changes in ventilation settings to assist the user in evaluating the effect of those changes on the ventilator strategy before the changes are implemented.Type: GrantFiled: July 16, 2012Date of Patent: October 15, 2013Assignee: Covidien LPInventors: Charles L. Wallace, Warren G. Sanborn, David Arnett, Jay Butterbrodt, Howard L. Ferguson

Publication number: 20130263857Abstract: Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.Type: ApplicationFiled: April 6, 2012Publication date: October 10, 2013Inventors: Samir S. Ahmad, Leonardo Alberto Baloa Welzien, Enrico Brambilla, Lauren Cheney, Iva Segalman, Simon Johnson

Patent number: 8550078Abstract: An assembly structured to inflate a retaining or pressure cuff associated with an artificial airway tube such as an endotracheal and/or tracheotomy tube and concurrently monitor pressure therein including a casing having an interior pressure chamber. A pump assembly is movably connected to the casing and structured to force fluid flow to the retaining cuff through said pressure chamber. An indicator member is disposed within the casing, is visually accessible through casing window, and is variably positionable dependent on and indicative of existing pressure within the retaining cuff. The existing pressure within the pressure chamber is substantially equivalent to that within the retaining cuff thereby facilitating the variable position of the indicator member to indicate pressure within the cuff. A junction is disposed between the casing and an inflation lumen to the restraining cuff and is structured to allow disconnection between the casing and the lumen but prevent reconnection thereto.Type: GrantFiled: March 10, 2010Date of Patent: October 8, 2013Assignee: Seedlings Life Science Ventures, LLC.Inventors: Stephen Jay Lowenstein, Michael R. Cole, Klaus D. Lessnau, Keith Rubin, James M. Sellers

Patent number: 8539945Abstract: A dose counter for a metered dose inhaler includes a force sensor, an electronic controller, a memory for storing data indicative of a remaining number of doses and an electronic display device coupled to the controller for displaying the remaining number of doses. The dose counter is attached or integrated into a base of a canister containing medicament such that force applied to the base of the canister is registered by the force sensor, the controller being configured to measure force applied to the dose counter when depressing the canister and being responsive to measured force to decrement the remaining number of doses stored in the memory and shown on the display device.Type: GrantFiled: August 12, 2010Date of Patent: September 24, 2013Assignee: Teva Pharmaceutical Industries Ltd.Inventors: Ian Solomon, Moti Goldhirsh

Publication number: 20130220326Abstract: This invention relates to a breath indicator that is receivable by a part of a breathing assistance apparatus that supplies gas to a patient. The indicator comprises an elongate body having a gas sampling end and an attachment end. The attachment end is adapted to attach to a part of a breathing assistance apparatus and for locating the gas sampling end. The gas sampling end is to be located in a region where gas from the patient is to be exhaled. The gas sampling end being in communication with a sensor comprising a detector material changeable between a first visual indicator state relating to an inhalation phase of the patient, and a second visual indicator state relating to an exhalation phase of the patient. The detector material is capable of changing between the visual indicator states at a sufficient rate to substantially correspond with the inhalation and exhalation phases of the patient.Type: ApplicationFiled: August 31, 2011Publication date: August 29, 2013Applicant: Fisher & Paykel Healthcare LimitedInventors: David Robert Kemps, Simon Boulton, Jonathan Mark Church

Patent number: 8517019Abstract: This application discloses a dose counter device of the type for use on an aerosol dispensing assembly having an aerosol container and an actuator. The dose counter device is used for indicating the release of a dose of aerosol medication caused by the application of a force, in an axial direction, on the aerosol dispensing assembly. The dose counter device has a cap, a slider and a first counter ring. The cap is moved in a first direction along an axis of the container, which causes movement of the slider in a first linear direction laterally, relative to the axis of the container, as a function of the movement of the cap in the first direction. The first counter ring is rotated through a first arc in a first circumferential direction about the axis of the container, as a function of the movement of the slider in the first linear direction.Type: GrantFiled: March 1, 2007Date of Patent: August 27, 2013Assignee: 3M Innovative Properties CompanyInventors: Richard D. Brewer, Peter D. Hodson, Graham R. Purkins, David J.C. Steven
