Device for enhancement and quality improvement of blood-related signals for use in a system for non-invasive measurements of blood-related signals

摘要

A disposable device is presented aimed at enhancing blood-related signals and improving their quality during non-invasive measurements of blood parameters. The device is applicable to a patient's finger or toe, and comprises a cover for wrapping at least a part of the finger or toe including a tip portion thereof in a manner to provide even pressurization of tissue within the wrapped portion with a pressure less than a systolic pressure. This results in enhancement and quality improvement of the measured blood-related signal. The cover is elastic and is shiftable along a longitudinal axis of the finger or toe between an inoperative folded position of the cover and an operative extracted position of the cover, in which it wraps the finger or toe portion including the tip portion and provides said even pressurization of the entire wrapped tissue. At least a portion of the cover is made of a material enabling the non-invasive measurements of the blood-related signal therethrough.
