Measurement And Control Of Body Fat Percent During Pregnancy
The present invention provides a method for measuring the body fat percent and fat accretion during pregnancy, which preferably utilizes a Fourier transform near infrared spectroscopy (FT-NIR) fat determination method. The FT-NIR results can be used to measure and monitor body fat percent, and used to measure the mother's fat accretion rate. A method to monitor weight gain in a pregnant subject is provided wherein the body fat percentage of the subject is maintained at a constant level during gestation, and the subject's fat accretion rate is monitored so as to follow the fat accretion rate provided by using pre-defined fat accretion determination formulae. By measurement of the body fat percent and fat accretion rates, the weight gain of a subject can be monitored and/or controlled during pregnancy.
WEARABLE FETAL MONITORING SYSTEM HAVING TEXTILE ELECTRODES
A seamless, smart fetal monitoring garment and methods of using thereof. The system includes a knitted or interwoven garment having a multiplicity of conductive textile electrodes for sensing maternal and fetal electrical vital signals. The maternal and fetal electrical vital signals are selected from a group including maternal heart rate, fetal heart rate and electromyogram (EMG) activities including uterine activities. The method includes wearing the garment, acquiring electrical mixed common, maternal and fetal vital signals from surface region of a pregnant woman, using the plurality of textile electrodes, optimally weighted summing-up the acquired signals, analyzing the summed-up signals to thereby extract the maternal signal and the fetal signal, including determining their heart rates, and including detecting health hazards and in some embodiments, including detecting a uterine contraction sequence suggesting the need to be hospitalized for birth giving.
Systems , devices, and methods for performing trans-abdominal fetal oximetry and/or trans-abdominal fetal pulse oximetry using diffuse optical tomography
Fetal tissue oxygenation may be performed transabdominally by, for example, receiving a plurality of detected electronic signals that correspond to light emitted from a pregnant mammal's abdomen and a fetus contained therein that has been detected by the detector and converted into the detected electronic signal. An indication of a depth of the fetus within the pregnant mammal's abdomen may be received and a portion of the detected electronic signals that correspond to light that was incident upon the fetus may be isolated responsively to the indication of the depth of the fetus using, for example, time of flight of photons that correspond to the detected electronic signals. A fetal tissue oxygen saturation level may then be determined using the isolated portion of the detected electronic signals that correspond to light that was incident upon the fetus.
METHOD OF NON-INTRUSIVELY MEASURING BRAINWAVE ACTIVITY IN A FETUS
A method of non-intrusively measuring brainwave activity in a fetus is provided. The method provides the steps of: directing at least a first monitoring sensor to a pregnant woman's body; measuring a first set of signals received by the at least first monitoring sensor; filtering non-fetal brainwave signals from the first set of signals, resulting in fetal brainwave activity signals; and determining fetal brainwave activity from the fetal brainwave activity signals.
Systems Using Fingerprint images as Diagnostic Detection systems for Type 2 Diabetes
Method and kits for determining a propensity to develop Type 2 diabetes mellitus (T2DM) in an individual by measuring an asymmetry of a captured fingerprint from the individual are described.
Flavonoid compounds of low toxicity for biological imaging applications
Flavonoid compounds that are selective for a protein, a portion or a living cell, or a portion of an organism may be used as biological imaging agents. The flavonoid compounds are useful for methods of imaging organisms such as zebrafish embryos and zebra fish. Flavonoid compounds may also be used to detect protein. Advantageously, flavonoids that selectively bind protein, a portion of a living cell, or a portion of an organism may exhibit a florescence turn-on mechanism, where the flavonoids that are selectively bound exhibit a florescence response when excited.
INTEGRATED ELECTRODE FOR SAMPLING OF LACTATE AND OTHER ANALYTES
The invention provides a biosensor for at least partial insertion in a fetal scalp, for monitoring an analyte in the body of the fetus, wherein the biosensor comprises a needle and a microdialysis element for sampling the analyte. The invention also provides a sensing system comprising the biosensor, configured to flow a liquid through the microdialysis element. The invention can be used for e.g. lactate sensing as well as releasing a pharmaceutical. Hence, the biosensor and/or sensing system may also be used for delivery of a pharmaceutical or nutrient to a fetus.
RH INCOMPATIBILITY DETECTION
One example implementation detects Rh incompatibility between a mother and a baby by utilizing a light emitter to project light into the flesh of a user, a light detector to measure voltage from light in the flesh of the user caused by the projected light, and an Rh analyzer to detect Rh incompatibility between a user and a fetus within the user based on the voltage.
FETAL HEALTH MONITOR
A wearable sensor apparatus is disclosed that includes a flexible substrate adapted to be coupled with a skin surface of an expectant mother. A conductor is disposed on the flexible substrate. The conductor can include micron-scale invaginations. The conductor can be capable of repeatable variation in resistance when subject to a strain. Also disclosed is a system for monitoring the health of a fetus in utero that includes a wearable sensor apparatus. The wearable sensor apparatus is configured to output a signal responsive to an electrical input. The system includes a computing system with one or more hardware processors. The computing system is programmed to implement a signal processing module configured to access the output signal from the wearable strain gauge and generate an output indicative of health of the baby in utero. The output can be based in part on the received output signal and previously stored correlations between signal data from the wearable strain gauge and observations of the system or of the mother. A user interface module can be provided and can be configured to display an output indicative of health of the baby in utero.
ELECTRONIC CATHETER STETHOSCOPE
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.
