PHYSIOLOGICAL SENSOR HAVING BIODEGRADABLE OPTICS

摘要

Medical sensor assemblies configured to provide enhanced patient comfort when worn over a period of time are provided. The medical sensor assemblies may include sensors in optical communication with one or more biodegradable light guides that facilitate the transmission of light to and from an internal tissue of the patient. The medical sensor assemblies may also include a bandage that facilitates coupling of the light guides to the sensor. Additionally or alternatively, a bandage may be positioned against an internal tissue to specifically direct the emitted light through the tissue. Such embodiments may provide enhanced light transmission between the emitter and detector of the sensors.

1. A physiological sensor assembly, comprising:
a physiological sensor, comprising:
a sensor body;an emitter disposed in the sensor body and configured to emit one or more wavelengths of light toward a patient; anda detector disposed in the sensor body and configured to detect the one or more wavelengths of light after transmission through a tissue of the patient; a first biodegradable light guide configured to be placed in optical communication with the emitter, wherein the first biodegradable light guide is configured to physically traverse a skin layer of the patient to transmit the one or more wavelengths of light emitted by the emitter to an internal tissue of the patient; and a second biodegradable light guide configured to be placed in optical communication with the detector, wherein the second light guide is configured to physically traverse the skin layer of the patient to transmit the one or more wavelengths of light transmitted by the emitter through the internal tissue to the detector to measure a physiological parameter of the internal tissue.
