Embodiment Construction

[0036] The accompanying drawings and descriptions of certain embodiments provided by the present invention do not limit the invention to these embodiments, but are provided for anyone skilled in the art to make and use the present invention. New fiber optic sensors and related methods of using fiber optic sensors are disclosed herein. In particular, embodiments are disclosed that use fiber optic sensors to monitor vital signs.

[0037] Fiber optics can be used as sensors to measure strain, temperature, pressure, and other quantities by altering the fiber such that the quantity to be measured modulates the intensity, phase, polarization, wavelength, or transit time of light passing through the fiber. There are four types of fiber optic sensors: intensity-based fiber optic sensors, spectrally based fiber-optic sensors, interferometric fiber-optic sensors, and multiplexed Distributed optical fiber sensors (multiplexed and distributed optical fiber sensors). Two of these types o...

Abstract

An intensity-based, micro-bending optical fiber sensor is disclosed herein, which is configured to acquire clean, stable, and reliable vital sign signals. Related systems and methods for vital sign monitoring are also provided herein. The sensor of various embodiments includes a multi-mode optical fiber, an LED light source, an LED driver, a receiver, and a single layer deformer structure. In various embodiments, the optical fiber and single layer deformer structure of the sensor are selected to meet specific parameters necessary to achieve a level of reliability and sensitivity needed to successfully monitor vital signs. In some embodiments, a specific sizing relationship exists between the optical fiber and the single layer deformer structure. In some embodiments, the sensor is configured to acquire ballistocardiograph waveforms.

Description

[0001] Cross-Referenced Related Applications [0002] This application claims priority under 35 U.S.C § 119(e) to U.S. Provisional Application No. 62 / 057237, filed September 30, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention mainly relates to the field of optical fibers, in particular to optical fiber sensors and methods for monitoring physiological parameters of patients. Background technique [0004] Health and wellness monitoring has become an area of ​​increasing concern with the advent of internet-connected devices and the digital healthcare industry. Monitoring vital signs such as heart rate, cardiac shock signals, and respiration rate is required both in and outside of healthcare settings. Within healthcare settings, vital sign tracking can be essential: for ensuring patient safety, diagnosing disease, monitoring patient progress, and planning patient care when healthcare providers are not at the bedsid...
