Systems And Methods For Determining Differential Pulse Transit Time From The Phase Difference Of Two Analog Plethysmographs
Systems And Methods For Determining Differential Pulse Transit Time From The Phase Difference Of Two Analog Plethysmographs
US Patent:
2013013, May 30, 2013
Filed:
Nov 30, 2011
Appl. No.:
13/307961
Inventors:
Daniel J. Peters - Longmont CO, US
Assignee:
Nellcor Puritan Bennett LLC - Boulder CO
International Classification:
A61B 5/00
US Classification:
600301
Abstract:
Systems and methods are provided for patient monitors which apply phase detection operations to analog signals to identify differential pulse transit time (DPTT). Photoplethysmograph (PPG) signals measured at two sensor sites may be processed by a phase detection system to identify phase information that allows the calculation of a DPTT. The phase detection system may process analog PPG signals in the analog domain to determine phase information. In some embodiments, the phase detection system may process optical oximetry sensor signals to determine phase information using, for example, interferometric methods.

Signal Processing Warping Technique
US Patent:
2011007, Mar 24, 2011
Filed:
Sep 13, 2010
Appl. No.:
12/880306
Inventors:
Edward M. McKenna - Boulder CO, US
Daniel Jon Peters - Longmont CO, US
Daniel Jon Peters - Longmont CO, US
Assignee:
Nellcor Puritan Bennett LLC - Boulder CO
International Classification:
A61B 5/145
US Classification:
600364, 600300
Abstract:
Methods and systems are provided for using time-frequency warping to analyze a physiological signal. One embodiment includes applying a warping operator to the physiological signal based on the energy density of the signal. The warped physiological signal may be analyzed to determine whether non-physiological signal components are present. Further, the same warping operator may be applied to signal quality indicators, and the warped physiological signal may be analyzed based on the warped signal quality indicators. Non-physiological signal components, or types of non-physiological noise sources, may be identified based on a comparison of the physiological signal with the signal quality indicators. Non-physiological signal components may also be identified based on a neural network of known noise functions. In some embodiments, the non-physiological signal components may be removed to increase accuracy in estimating physiological parameters.

Daniel J. Peters - Longmont CO, US
Assignee:
Nellcor Puritan Bennett LLC - Boulder CO
International Classification:
H01J 27/14, H05K 9/00
US Classification:
250239, 361818, 361820
Abstract:
Embodiments described herein may include devices and methods of manufacturing devices for sensing and monitoring physiological parameters of a patient. Specifically, certain embodiments disclose the use of conductive and nonconductive overmold materials to protect the device, increase reliability, increase comfort, and increase accuracy of the parameters measured.
Tracheal Tube Locating System And Method
Tracheal Tube Locating System And Method
US Patent:
8548564, Oct 1, 2013
Filed:
Apr 3, 2009
Appl. No.:
12/418454
Inventors:
Daniel J. Peters - Longmont CO, US
Edward McKenna - Boulder CO, US
Edward McKenna - Boulder CO, US
Assignee:
Covidien LP - Mansfield MA
International Classification:
A61B 5/00
US Classification:
600424, 12820026, 12820714
Abstract:
According to various embodiments, a sensor may be placed on a patient chest adjacent to a desired position of a distal end of a tracheal tube. The sensor may be configured to emit an electromagnetic field into the patient and detect perturbations to that field caused by the presence of the tracheal tube. As the tube is inserted within the trachea, the sensor may detect the tube when the distal end passes within range of the sensor, indicating that a proper insertion depth has been reached. In certain embodiments, multiple sensors may be placed along the chest adjacent to the trachea to determine a distance between the tube and an anatomical structure. The distance information may provide an indication as to whether the tracheal tube is properly placed within the trachea.

International Classification:
A61B 5/024, A61B 5/026, A61B 5/02, A61B 5/08, A61B 5/00
US Classification:
600301, 600504, 600500, 600508, 600529, 600300
Abstract:
Present embodiments relate to systems, methods, and devices for decomposing a physiological signal of a patient using empirical mode decomposition (EMD). In one embodiment, the EMD algorithm may involve identifying a frequency component, referred to as an intrinsic mode function, in the physiological signal. The physiological signal may be decomposed into one or more intrinsic mode functions through multiple iterations of the EMD algorithm. Each subsequent mode function may have a different frequency component of the original physiological signal input into the EMD algorithm. In some embodiments, each mode function may be further analyzed and/or processed to determine various physiological data corresponding to blood flow in the patient.
