Patent Application Titled "Time Alignment Display Technique for a Medical Device" Published Online

February 11, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors Carnes, Tony C. (Gainesville, FL); Szymanski, Henry (Boulder, CO); Birkett, Kevin R. (Newberry, FL), filed on February 27, 2013, was made available online on January 30, 2014 (see also Covidien Lp).

The assignee for this patent application is Covidien Lp.

Reporters obtained the following quote from the background information supplied by the inventors: "A wide variety of devices have been developed for non-invasively monitoring physiologic characteristics of patients. For example, an oximetry sensor system may non-invasively detect various patient blood flow characteristics, such as blood-oxygen saturation of hemoglobin in blood, volume of individual blood pulsations supplied to tissue, and/or the rate of blood pulsations corresponding to each heart beat of a patient. During operation, the oximeter sensor emits light and photo-electrically senses the absorption and/or scattering of the light after passage through perfused tissue. A photo-plethysmographic waveform, which corresponds to cyclic attenuation of optical energy through the patient's tissue, may be generated from the detected light. Additionally, one or more physiologic characteristics may be calculated based upon an amount of light absorbed or scattered. More specifically, the light passed through tissue may be selected to be of one or more wavelengths that may be absorbed and/or scattered by the blood in an amount correlative to the amount of the blood constituent present in the blood. The amount of light absorbed and/or scattered may then be used to estimate the amount of blood constituent in tissue using various algorithms.

"The automated capture of sensed physiologic values from one or multiple medical devices may lead to improved patient care. However, the act of capturing and displaying the data/information from medical sensors does not necessarily improve care. What may improve care is the ability to present the captured data/information in new ways and to identify cause and effect relationships for such captured data/information."

In addition to obtaining background information on this patent application, NewsRx editors also obtained the inventors' summary information for this patent application: "The present disclosure relates to systems and methods that generally include at least one sensor and a monitor in operable communication with the at least one sensor. The systems and methods allow the monitor to be configured to display a plurality of graphs each representing a measured physiologic parameter versus time, the plurality of graphs configured to be aligned with respect to each other along a time axis. A marker moves along the time axis of each of the plurality of graphs in response to an input received from an input unit.

"The aspects and features of the present disclosure are advantageous in that they provide a marker that is a time scroll bar. The aspects and features of the present disclosure are advantageous in that they allow a graph of each measured physiologic parameter to be indicative of a trend of the measured physiologic parameter over a period of time. The aspects and features of the present disclosure are advantageous in that they allow the plurality of graphs to be stacked with respect to each other in a vertical orientation and in a non-overlapping manner. The aspects and features of the present disclosure are advantageous in that they allow the marker to be a vertical time scroll bar configured to intersect the plurality of graphs at a common point on the time axis.

"The aspects and features of the present disclosure are advantageous in that they allow the marker to be moved to a previous measured time period or point in time corresponding to historical medical events of interest for evaluating the measured physiologic parameters during that measured time period or point in time. The aspects and features of the present disclosure are advantageous in that they provide, as the marker is moved across one graph of the plurality of graphs to a point in time, all the measured physiologic parameters of all of the plurality of graphs to be displayed on a monitor at that point in time and to be simultaneously analyzed. The aspects and features of the present disclosure are advantageous in that they provide the monitor with a storage module for storing values the measured physiologic parameters, where the values are periodically recorded during predefined points of time. The aspects and features of the present disclosure are advantageous in that they provide, by moving the marker across a graph of the plurality of graphs, a direct relationship to be established between all the physiologic parameters at any given point in time.

"Certain embodiments of the present disclosure may include some, all, or none of the above advantages and/or one or more other advantages readily apparent to those skilled in the art from the drawings, descriptions, and claims included herein. Moreover, while specific advantages have been enumerated above, the various embodiments of the present disclosure may include all, some, or none of the enumerated advantages and/or other advantages not specifically enumerated above.
