Embodiments disclosed herein are directed to devices, systems, and methods for monitoring pregnancy of a female pregnant subject. For example, a pregnancy monitoring system can detect movement or motion of a pregnant subject and/or of the fetus in the pregnant subject. Additionally or alternatively, the pregnancy monitoring system can detect internal and/or external source loads applied to the pregnant subject. In an embodiment, the pregnancy monitoring system can compare and/or correlate two or more loads, one to another (e.g., to produce an output that is in part based on such comparison and that is related to the wellbeing of the pregnant subject and/or of the fetus). For example, the pregnancy monitoring system can include a controller that is configured to determine and compare two or more loads based on signals received from one or more sensors that can be positioned on the pregnant subject.

This invention relates to an ingestible drug delivery device configured for wireless communication with other ingestible drug delivery devices.

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.

A method for imaging and quantifying placental blood perfusion using magnetic resonance imaging is disclosed. The method provides a noninvasive means of assessing placental function and oxygenation from T.sub.2* images without the administration of an exogenous contrast agent. The method provides quantitative information regarding the number and spatial distribution of perfusion domains which subdivide the placenta into functional units where oxygen transport occurs, along with estimates of fetal oxyhemoglobin concentration, descriptors of placental oxygen reserve, and parameters representing the facility with which oxygen transport from the maternal to fetal vasculature occurs.

The present invention relates to a foldable case-integrated multi-device and a health management system using the same, in which health management and life management functions are implemented by introducing various sensors into a foldable case for a communication device. According to the present invention, a sensor module configured to measure biometric information is contained in a foldable case, and power supply, data processing and analysis, and display are implemented using internal components of the communication device, thereby providing a cutting-edge health care function while maintaining a communication device in a light, thin, short and small form.

The various embodiments herein relate to systems, devices, and methods for tracking abdominal orientation and activity for purposes of preventing or treating conditions of pregnancy or other types of medical conditions. In certain specific embodiments, the system, device, or method relates to identifying abdominal orientation risk values, calculating and updating a cumulative risk value, comparing the cumulative risk value to a threshold, and outputting a warning when the cumulative risk value crosses the threshold.

A vaginal dilation device is provided that may include any of a number of features. One feature of the vaginal dilation device is that it is configured to dilate vaginal tissue during labor to prevent tissue damage. Another feature of the vaginal dilation device is that it can be manually controlled to dilate vaginal tissue, or can be automatically controlled to dilate vaginal tissue. In some embodiments, the vaginal dilation device is configured to measure a force applied by the device to tissue. In other embodiments, the vaginal dilation device is configured to apply a constant force to tissue. In other embodiments, the vaginal dilation device is configured to expand at a constant rate. Methods associated with use of the vaginal dilation device are also provided.

This invention relates to an ingestible drug delivery device configured for wireless communication with other ingestible drug delivery devices.

Disclosed herein are devices, systems, and methods related to monitoring intrauterine pressure. An example method may include inserting a catheter assembly into an uterus of a patient such that a sensor of the catheter assembly is placeable within the uterus and an expandable region is positioned to facilitate dilation of a cervix, the sensor is operable such that an intrauterine pressure measurement is obtainable while the expandable region is expanded. Also, the monitoring intrauterine pressure may include expanding the expandable region to facilitate dilating the cervix. Furthermore, the monitoring intrauterine pressure may include obtaining an intrauterine pressure measurement of an amniotic space of the uterus.

Technology is disclosed for a cat litter that can be used to diagnose feline medical conditions. A cat litter contains an additive, e.g., a chemical agent, such as a natural and/or synthetic agent, that changes in color when it comes in contact with cat urine or feces. Based on the color it can be determined whether the cat has a medical condition, such as particular illness. For example, if the litter turns yellow when it comes in contact with the urine, it can indicate that the cat is healthy. If the litter turns to a color other than yellow, e.g., green, it can indicate that the cat has some illness. The cat then be taken to a veterinary doctor for further diagnosis. The chemical agent aids in detection and diagnosis through interaction of materials that change colors to indicate reactions with specific chemicals, cells, molecules, DNA and/or materials. The technology can be implemented for medical diagnosis and detectionfor humans and/or animals.
