Provided are a device and method for receiving a fetal heart rate (FHR) signal at each interval during a monitoring period, receiving a uterine pressure (UP) signal at each of the intervals to obtain a plurality of FHR-UP signal pairs, and extracting a feature value for each FHR-UP signal pair, with the feature value being extracted from a predefined alphabet of feature values.

Independent component analysis may be performed on a plurality of detected electronic signals to separate signals within the detected electronic signals that are contributed by different sources. Each of the plurality of detected electronic signals may be received from a separate detector and may correspond to a detected optical signal emanating from a pregnant mammal's abdomen and a fetus contained therein. The detected optical signals may correspond to light that is projected into the pregnant mammal's abdomen from a light source. The separated signals may be analyzed to determine a separated signal that corresponds to light incident upon the fetus, which may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. An indication of the fetal hemoglobin oxygen saturation level may then be provided to the user.

A multi-lumen catheter for monitoring uterine contraction pressure having an elongated body configured and dimensioned for insertion into a bladder of a patient, the catheter having a first lumen, a second lumen, and a first balloon at a distal portion, the first lumen communicating with the first balloon. The second lumen communicates with the bladder to remove fluid from the bladder. The first balloon is filled with a gas to form along with the first lumen a gas filled chamber to monitor pressure within the bladder to thereby monitor uterine contraction pressure of the patient.

A graphical user interface is provided displaying a first viewing window selected from a set of possible viewing windows conveying respective feature measurements related to labor progression. At least one viewing window in the set of possible viewing windows conveys a given feature measurement and a safety limit associated to the given feature measurement. The graphical user interface also displays at least one control allowing a user to select a subset of viewing windows from the set of possible viewing windows, the subset of viewing windows including at least one viewing window other than the first viewing window. The selected subset of viewing windows is displayed simultaneously with the first viewing window. In response to the given feature measurement exceeding the associated safety limit, information is displayed to attract the attention of the user to the viewing window conveying the given feature measurement.

A uterine activity analysis apparatus, comprising a rendering device at least one controller coupled to the rendering device, and configured to acquire a uterine activity signal (UAS) corresponding to uterine activity of a patient; determine uterine activity information based upon the acquired UAS and render, on the rendering device, content based at least in part including UAS upon the determined uterine activity information. The controller may compare the determined uterine activity information with threshold uterine activity information and provide clinical decision support (CDS) based upon the decision. Furthermore, the controller may render a breathing guide to illustrate a preferred breathing pattern, when the start of a contraction is detected.

Uterine activity tools and methods of use thereof. The uterine activity tools of this invention are designed to provide clinicians with information to evaluate uterine activity of a pregnant patient utilizing a fetal monitor with a tocodynamometer external pressure sensor (TOCO) and/or an intrauterine pressure catheter (IUPC). The tool of this invention displays vital information for assessment and documentation of uterine activity including date, time, mode, contraction frequency, contraction duration, contraction intensity, resting tone, relax time, calculated Montevideo units, and number of contractions in a selected time period.

Endoscope systems include an endoscope shaft assembly which comprises a shaft having a working channel, an inflow channel configured to be coupled to a fluid source, and an outflow channel configured to be coupled to a negative pressure source. A hub is coupled to a proximal portion of the shaft, and an image sensor is disposed on a distal portion of the shaft. A control unit is configured to adjust both a fluid inflow from the fluid source through the inflow channel to the working space and a fluid outflow to the negative pressure source through the outflow channel from the working space. A handle assembly is detachably connected to the hub of the endoscope shaft assembly, and the handle assembly comprises a control pad having at least one actuator which may be wired or wirelessly linked to the controller for adjusting fluid inflows and outflows through the inflow channel and outflow channel in the shaft.

An electronic catheter stethoscope measures and analyzes acoustic fields and dynamic pressure variations in the gaseous or liquid fluid inside a conventional medical catheter that is positioned in a patient's urologic, digestive, reproductive, cardiovascular, neurological or pulmonary system. Measurement transducers are installed in a housing connectable to multiple preselected medical catheters. The transducers detect bodily functions that are transmitted to the preselected catheter from within the body. The transducers, housing, electrical interface and signal processing electronics are positioned outside the body.
