Trans-abdominal fetal pulse oximetry and/or uterine tone determination devices and systems with adjustable components and methods of use thereof

A non-transitory computer-readable medium storing a set of instructions, wherein execution of the set of instructions by a processor cause the processor to:

• receive an indication of a distance between an epidermis of a pregnant mammal's abdomen and a fetus contained therein;
• determine an optimum distance between one or more detectors of a plurality of detectors configured to be located at a position on the pregnant mammal's abdomen and a light source;
• send an instruction to a motor to move the one or more detectors of the plurality of detectors or the light source responsively to the determined optimum distance, wherein the motor is housed within a housing coupled to the light source and the plurality of detectors, the motor being mechanically coupled to arms with each arm mechanically coupled to the light source or respective detector of the plurality of detectors so that one or more detectors of the plurality of detectors or the light source are configured to move to optimize a delivery of light to the fetus or a detection of light incident upon or emanating from the fetus;
• receive a plurality of detected electronic signals, each of the plurality of detected electronic signals being received from a separate detector of the plurality of detectors communicatively coupled to the processor and corresponding to a detected optical signal emanating from the pregnant mammal's abdomen and the fetus contained therein, wherein each detected optical signal has been converted, by the respective detector, into one of the plurality of the detected electronic signals;
• receive a position for each of the plurality of detectors;
• select a detected electronic signal from the plurality of detected electronic signals responsively to the position of the detector corresponding to the selected detected signal and the indication of the distance between the epidermis of the pregnant mammal's abdomen and the fetus contained therein;
• analyze the selected detected signal to determine a fetal hemoglobin oxygen saturation level of the fetus;
• and
• facilitate provision of an indication of the fetal hemoglobin oxygen saturation level to a user.

A method comprising:

• receiving, by a processor, a plurality of detected electronic signals, each detected electronic signal of the plurality corresponding to an optical signal emanating from the abdomen of a pregnant mammal;
• receiving, by a processor, an indication of a distance between an epidermis of the pregnant mammal's abdomen and a fetus contained therein;
• selecting, by the processor, a first detected electronic signal from the plurality that corresponds to light that penetrates the maternal abdomen to a first depth responsively to the indication of the distance between the epidermis of the pregnant mammal's abdomen and the fetus contained therein, the first depth being less than a distance between an epidermis of a pregnant mammal's abdomen and a fetus contained therein;
• selecting, by the processor, a second detected electronic signal from the plurality that corresponds to light that penetrates the maternal abdomen to a second depth responsively to the indication of the distance between the epidermis of the pregnant mammal's abdomen and the fetus contained therein the second depth being more than a distance between an epidermis of a pregnant mammal's abdomen and a fetus contained therein;
• filtering, by the processor, the second detected signal using the first detected signal, thereby isolating a portion of a second detected signal that is contributed by the fetus, thereby generating a fetal signal;
• determining, by the processor, a fetal hemoglobin oxygen saturation level using the fetal signal;
• and
• providing the fetal hemoglobin oxygen saturation level to a display device.
