A first region of interest and a second region of interest are set respectively including a first end and a second end of a blood vessel of interest running in an umbilical cord. A template representing a fluctuation of a pulse at the first end is produced from a change of brightness information in the first region of interest. A graph representing a fluctuation of a pulse at the second end is produced from a change of brightness information in the second region of interest. A propagation time of blood is calculated by identifying a portion, in the graph, which matches the template. A length of the umbilical cord is estimated based on the propagation time.

A physiological sensor has an optic assembly, an acoustic assembly and an attachment assembly. The optic assembly has an optic transducer that is activated so as to transmit a plurality of wavelengths of light into a tissue site and to detect the light after attenuation by pulsatile blood flow within the tissue site. The acoustic assembly has an acoustic transducer activated so as to respond to vibrations at the surface of the tissue site. The attachment assembly affixes the optic assembly and acoustic assembly to the tissue site, such as along one side of a person's neck or the forehead. A sensor cable extends from the attachment assembly so as to transmit an optic transducer signal and an acoustic transducer signal to a monitor for calculation of physiological parameters.

An apparatus for monitoring an obstetrics patient during labour is provided. The apparatus receives a contraction signal conveying information related to occurrences of uterine contractions over time and processes his signal to derive a sequence of rates of uterine contractions over time. The apparatus also implements a Graphical User Interface (GUI) presenting a tracing of at least part of the sequence of rates of uterine contractions over time along with a threshold rate of uterine contractions GUI is dynamically adapted over time based on the contraction signal received. The sequence of rates of uterine contractions derived over time is also processed to detect occurrences of anomalous contraction rates and to identify one or more portions of the tracing corresponding to sustained anomalous contraction rate segments during which anomalous contraction rates have persisted for time durations exceeding a pre-determined time duration. The GUI is configured to trigger an alarm event in response to identification of a specific sustained anomalous contraction rate segment.

A system for monitoring fetal health data and mother health data comprises a belly-covering garment that is configured to at least partially cover a belly and to hold one or more sensor modules directly adjacent to the belly. One or more sensor modules disposed within the belly-covering garment. The one or more sensor modules comprise a pulse-oximeter sensor that gathers pulse oximetry data from the mother through contact with the belly. The one or more sensor modules also comprise an accelerometer sensor that gathers movement data from the mother. Additionally, the one or more sensor modules comprise a fetal sensor that gathers health data from a fetus within the belly.

An extraction period specification unit specifies an extraction period (extraction section) for an M-mode image. A model expansion/contraction unit establishes a contour model (initial configuration) in relation to the specified extraction period while expanding/contracting the contour model in the direction of the time axis so as to conform with the extraction period. A node position change unit performs, for each node forming a plurality of node strings included in the established contour model, an edge (contour) search while successively changing the positions of the nodes, resulting in the formation of a revised contour model comprising a plurality of nodes at an edge detection position. A trace unit carries out interpolation on a plurality of node strings included in the revised contour model, thereby generating a plurality of trace lines simulating a plurality of contour lines.

An event-driven medical treatment data notification system is disclosed. Embodiments are directed to a treatment protocol for detecting Return of Spontaneous Circulation by employing a Doppler effect analysis on a signal transmitted at a patient's heart. A reflected signal is evaluated to determine if the patient's heart is moving, thereby indicating that the patient's heart is beating and, therefore, that blood is flowing.
