Embodiment Construction

[0081] Described herein are systems, devices, and methods for transabdominal fetal oximetry and / or fetal pulse oximetry. Additionally or alternatively, the systems, devices, and methods described herein may be used to determine uterine tone in a pregnant mammal, for example, to monitor uterine contractions in a pregnant mammal during labor and delivery.

[0082] The key output of fetal oximetry and / or fetal pulse oximetry is the oxygen saturation of fetal hemoglobin (also referred to herein as "fetal hemoglobin oxygen saturation level" and "oxygen saturation level"), which is also understood is the percentage of hemoglobin bound to oxygen present in fetal blood. Oxygen saturation levels of fetal blood can be used by trained medical professionals to assess the health of the fetus and the level of hypoxic stress it may encounter during, for example, labor and delivery. Fetal blood oxygen saturation values ​​are usually in the range of 30-60%, with any value below 30% indicating...

Abstract

A system and/or device for transabdominal fetal oximetry and/or fetal pulse oximetry and/or uterine tone determination may include one or more articulating, adjustable, and/or selectable components such as a light source and/or a photodetector. In some embodiments, the positioning of a light source and/or detector may be adjustable. The articulation and/or adjustment of position of the light source and/or photodetector may be in any plane (X, Y, and/or Z) and, in some instances, may be responsive to a fetal position within a maternal abdomen. Light detected by the detectors may be used to determine a fetal hemoglobin oxygen saturation level and/or a muscular state (e.g., contracted or relaxed) of the pregnant mammal's uterus.

Description

[0001] related application [0002] This application is a U.S. Provisional Patent Application entitled "Transabdominal Fetal Pulse Oximetry and / or Uterine Tonometry Apparatus and System with Articulating Light Sources and / or Light Detectors and Methods of Using the Same," filed December 29, 2017 Nonprovisional Application No. 62 / 611,830, and claiming priority thereto, is hereby incorporated by reference in its entirety. technical field [0003] The present invention belongs to the field of medical devices, more specifically, to the field of transabdominal fetal oximetry, transabdominal fetal pulse oximetry and optical uterine tension determination. Background technique [0004] Oximetry is a method used to determine the oxygen saturation of hemoglobin in mammalian blood. Typically, 90% (or more) of the hemoglobin in an adult is saturated (ie, bound with oxygen) with oxygen, whereas only 30-60% of the hemoglobin in fetal blood is saturated with oxygen. Pulse oximetry is a t...
