Device for enhancement and quality improvement of blood-related signals for use in a system for non-invasive measurements of blood-related signals
First Claim
1. A disposable device for use in a method of non-invasive measurements of blood-related signals from a portion of a patient'"'"'s finger or toe, wherein the method includes application of pressure, substantially less than a systolic pressure, to the portion of the patient'"'"'s finger or toe in a manner provide even pressurization of said portion, application of an external field to a measurement location within the pressed portion, detection of a response of the measurement location to said external field, and generation of data indicative of blood-related signals, the device comprising:
- a cover for wrapping at least a portion of the finger or toe, to thereby provide the even pressurization of the entire wrapped portion;
said cover being elastic, having a substantially circular cross-section, and being 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 the cover wraps the finger or toe portion including tip portion and provides said even pressurization of the entire wrapped tissue with the pressure less than the systolic pressure;
at least a portion of the cover being made of a material enabling the non-invasive measurements of the blood-related signal through said at least portion of the cover, said even pressurization of the body portion under measurement provided by the device resulting in that said response is at least two times higher than that obtained with no such even pressurization.

Abstract
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.
