Magnetic enhancement in determination of physiological blood parameters

摘要

Systems and methods for measuring a physiological parameter of blood in a patient are provided herein. An example method includes establishing with a magnetic array, an first magnetic field along tissue of the patient inserted into the magnetic array and a second magnetic field perpendicular to the tissue, emitting optical signals into further tissue of the patient during at least a first alignment of the magnetic array around the tissue, detecting characteristics of the optical signals, and identifying a value of a physiological parameter based on at least the characteristics of the optical signals.

1. A system for measuring a physiological parameter of blood in a patient, the system comprising:
a magnetic array having an opening therein configured to have tissue of the patient inserted therein and simultaneously establish in the tissue an axial magnetic field and a radial magnetic field perpendicular to the axial magnetic field; an emitter configured to emit a first optical signal into the tissue during a first angular configuration between the emitter and the magnetic array, and emit a second optical signal into the tissue during a second angular configuration between the emitter and the magnetic array the second angular configuration being different from the first angular configuration; a detector configured to detect characteristics of the first optical signal and the second optical signal; a user interface; and a processing module configured to:
calculate a differential of the characteristics of the first and the second optical signals;identify a value of a physiological parameter from the differential; anddisplay the physiological parameter on the user interface.
