SYSTEMS, DEVICES, AND METHODS FOR PERFORMING TRANS-ABDOMINAL FETAL OXIMETRY AND/OR TRANS-ABDOMINAL FETAL PULSE OXIMETRY USING A HEARTBEAT SIGNAL FOR A PREGNANT MAMMAL
First Claim
1. A fetal monitoring system, comprising:
- a detector adapted to detect light reflected from an abdomen of a pregnant mammal and a fetus contained therein, the reflected light corresponding to incident light projected into the pregnant mammal'"'"'s abdomen and the fetus by a light source, the detector being further adapted to convert the detected light into a reflected electronic signal and communicate the reflected electronic signal to a processor; and
a processor in communication with the detector, the processor being configured to;
(i) isolate a portion of the reflected electronic signal that corresponds to light reflected from the fetus from the reflected electronic signal, the isolation comprising;
(a) receiving the reflected electronic signal from the detector,(b) receiving a heartbeat signal for the pregnant mammal,(c) determining a portion of the electronic received signal that corresponds with the heartbeat signal for the pregnant mammal; and
(d) subtracting the portion of the electronic received signal that corresponds with the heartbeat signal for the pregnant mammal from the electronic received signal,(ii) analyze the isolated portion of the reflected electronic signal to determine a hemoglobin oxygen saturation level of the fetus, and(iii) facilitate provision of an indication of the hemoglobin oxygen saturation level of the fetus to a display device.

Abstract
Light reflected from a pregnant woman'"'"'s abdomen and fetus contained therein that has been received by a detector and converted into a reflected electronic signal may be received by a processor. A portion of the reflected electronic signal that is reflected from the fetus may be isolated and the isolated portion of the reflected electronic signal may be analyzed to determine a fetal hemoglobin oxygen saturation level of the fetus. The isolation may be achieved by synchronizing the reflected electronic signal with a fetal heartbeat signal and multiplying the synchronized reflected electronic signal by the synchronized fetal heartbeat signal.

15. A method for determining a fetal hemoglobin oxygen saturation level, the method comprising:
-
receiving, by a processor, a heartbeat signal for a pregnant mammal from a monitor communicatively coupled to the processor; receiving, by the processor, a reflected electronic signal from a detector communicatively coupled to the processor, the reflected electronic signal corresponding to light reflected from a pregnant mammal'"'"'s abdomen and a fetus contained therein, the reflected light being a portion of light projected, by a light source, into the pregnant mammal'"'"'s abdomen and fetus contained therein, wherein the reflected light has been converted, by the detector, into the reflected electronic signal; processing, by the processor, the reflected electronic signal to isolate a portion of the reflected electronic signal that is reflected from the fetus, the processing of the reflected electronic signal comprising; determining a portion of the electronic received signal that corresponds with the heartbeat signal for the pregnant mammal; and subtracting the portion of the electronic received signal that corresponds with the heartbeat signal for the pregnant mammal from the electronic received signal, analyzing, by the processor, the isolated portion of the reflected electronic signal to determine a fetal hemoglobin oxygen saturation level of the fetus, and facilitating, by the processor, provision of an indication of the fetal hemoglobin oxygen saturation level to a display device. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
