An electronic system for foetal surveillance includes at least two ultrasound sensors to emit and receive ultrasound waves either simultaneously, or simultaneously by groups, or sequentially. The ultrasound sensors configured to be positioned on at least one maternal abdominal portion to cover the foetal cardiac structure in movement and carry out measurements of foetal cardiac frequency. The distance between two ultrasound sensors is maintained by a link. A controller controls the ultrasound sensors with a piece of information to control the ultrasound waves sent to at least one ultrasound sensor. A processor to process the ultrasound signals to continuously estimate the position of the heart, the foetal cardiac rhythm and the foetal movements of one or more foetuses on the basis of the signal or signals received from the ultrasound sensors.

A method comprising: acquiring via a network biogas information representing a concentration of furfural of the user acquired by a sensor that detects the furfural discharged from a skin surface of the user; obtaining the reference information representing a lower limit of a normal range of the concentration of furfural per unit period of time, using a memory storing the reference information; and outputting information related to stress of the user an information terminal of the user, after it is determined that a frequency that concentration of the furfural of the user per the unit period of time is less than the lower limit of the normal range tends to increase, based on the biogas information acquired in a pregnancy period of the user.

In order to objectively grasp a stress state of a user and to prevent postpartum depression, biological gas information is acquired via a network, where the biological gas information indicates a concentration of heptadecane of the user and is obtained by a sensor that detects heptadecane released from a skin surface of the user. From a memory storing information including an upper limit of a normal range of the concentration of heptadecane per unit period, the information indicating the upper limit of the normal range is read out. When a frequency in the unit period with which the concentration of heptadecane of the user exceeds the upper limit of the normal range is determined to have an increasing tendency based on the biological gas information obtained during a pregnancy period of the user, the information related to stress of the user is output to an information terminal of the user.

The invention is generally a system, apparatus, and method for monitoring and measuring a change in intrauterine pressure without rupturing the amniotic sac. A catheter is coupled to a pressure sensing module. The pressure sensing module is configured with a chamber that is in fluid communication with a balloon of the catheter. The chamber includes a pressure-sensing membrane coupled to sensing circuitry. The sensing circuitry is configured to detect a pressure applied to the pressure-sensing membrane and communicate the condition to a monitor of the system. Methods include inserting the catheter through the cervix so that the balloon may be inflated and situated in the lower segment of the uterus, resting against the amniotic sac. Because the balloon of the catheter is in fluid communication with the pressure-sensing membrane, pulsations of the amniotic sac will be sensed by the sensing circuitry of the pressure sensing module.

A fetal Doppler (10) and a detection method, which relate to the technical field of medical devices. The fetal Doppler (10) comprises a housing (1, a fetal detection unit (20) and a maternal parameter detection unit (30), wherein the fetal detection unit (20) and the maternal parameter detection unit (30) are respectively used for collecting fetal physiological data and maternal physiological data; a controller (7) is arranged in an internal cavity of the housing (1); and the controller (7) is used for analyzing the collected fetal physiological data and maternal physiological data, so as to obtain a fetal heart rate and a maternal parameter. The same fetal Doppler (10) is used, such that the instrument cost is reduced; and maternal and fetal parameters can be acquired at the same time by directly using the same fetal Doppler (10), such that an instrument structure is simplified, and the detection efficiency of the maternal and fetal parameters is improved.

A system and method are provided for generating images of a portion of a subject including an organ receiving blood from multiple, different supplies. The method includes accessing MR data acquired from a subject having received a dose of a material configured to change MR contrast. The method also includes reconstructing the MR dataset into a first set of MR images using a first reconstruction process configured to weight the first set of MR images to the material configured to change the MR contrast and reconstructing the MR dataset into a second set of MR images using a second reconstruction process configured to weight the second set of MR images against the material configured to change the MR contrast. The method further includes displaying the first set of MR images and the second set of MR images to selectively display blood flow from each of the multiple, different supplies.

The disclosed apparatus, systems and methods relate to tracking abdominal orientation and activity for purposes of preventing or treating conditions of pregnancy, respiratory diseases or other types of medical conditions. In certain specific embodiments, the system, device, or method relates to identifying abdominal or sleep position 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 garment shaped to approximate the abdomen of an expectant mother having a layered laminated conductive material adhered to the garment is disclosed. A portion of the laminated material is configured to directly contact the skin of the maternal abdomen to create an electrical signal connection. A portion of the layered laminated material comprises a stretchable circuit assembly having a substrate with an adhesive layer, a thermoplastic layer, a conductive layer and an encapsulating layer. A monitor controller is disposed about the garment and is configured to receive electrical signals from the circuit assembly and transmit information related to the electrical signals to a remote location.

A system for monitoring health parameters of a user includes a housing including: a plurality of sensors disposed on an outer surface of the housing or within the housing for measuring a plurality of parameters of interest; a processor disposed in the housing and communicatively coupled to the plurality of sensors; a coupling element on the housing for coupling the housing to an accessory; and an accessory identifier positioned on or within the housing and communicatively coupled to the processor.
