FETAL HEART RATE MONITORING DEVICE

    The present disclosure generally relates to monitoring fetal heart rates. More specifically, but not exclusively, the disclosure relates to display of one or more fetal heart rates on a single fetal strip.

    It is desirable in obstetrics to monitor and record to the condition of the fetus. Fetal monitors have been developed for monitoring and recording fetal heart rate and uterine activity. In the case of multiple fetuses in the womb, it becomes essential to separately monitor the heart rate activities of each fetus. The heart rate can be displayed on a display screen of a monitor. Further, there may be more than one heart rate that needs to be displayed. While various methods and systems have been developed, there is still room for the improvement. Thus, a need persists for further contributions in this area of technology.

    The disclosure provides a monitoring device that can display one or more fetal heart rate activity on a single fetal strip. Heart rates from multiple fetal strips can be combined into a single fetal strip and can be displayed simultaneously on the single monitor. In one illustrative embodiment, the heart rate waveform of each fetus can be vertically displayed in a sequence. The wave form for each fetus can be displayed using different colors for each, which can enable the operator to distinguish between heart rate of each fetus.

    The monitoring device can take the fetal heart rate input from a plurality of physiological sensors which can be continuously monitoring the heart rate of a fetus. The sensors can be configured to identify individual heart rate activity of multiple fetuses. Further, the sensors can be configured to transmit the identified heart rates to a single fetal strip. In one illustrative embodiment, the heart rate can be calculated by the ECG signal monitored by using an intrauterine probe, which is noninvasive to the fetus.

    Fig. 1 illustrates a monitor device 100 with a display screen 110 displaying four fetal heart rates on single screen. The four different fetal heart rates can be shown in different texture lines FHR1, FHR2, FHR3 and FHR4. It should be appreciated that the

fetal heart can be shown in different colors. It should also be appreciated that the device 100 can display one or more fetal heart rate wave forms simultaneously. Furthermore,
in one illustrative embodiment, the device 100 can generate a visual and/or audio alarm when the fetal heart rates deviate out of a predefined range. It should further be appreciated that the multiple waveforms shown on the display screen can also be printed.

    Fig. 2 illustrates a block diagram 200 of the fetal heart rate monitoring device 100. The figure shows a patient 12 and a physiological sensor 14. The physiological sensor 14 can be configured to sense the fetal heart rates. In one illustrative embodiment, a fetal scalp electrode, ultrasound transducer or multiple intrauteri...
