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 applying to a patient'"'"'s finger or toe in non-invasive measurements of blood-related parameters, derived from a measured response of a measurement location in the finger or toe to a predetermined external field, wherein:
- the device comprises a cover for wrapping at least a portion of the finger or toe including a tip portion thereof in a manner to provide even pressurization of the entire wrapped portion with a pressure less than a systolic pressure. thereby providing enhancement and quality improvement of measured blood-related signals;
said cover is elastic, has a substantially circular cross-section, 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 with the pressure less than the systolic pressure;
at least a portion of the cover is made of a material enabling non-invasive measurements of the blood-related signal therethrough.

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.

27. A method for obtaining enhanced and quality improved blood-related signals from a portion of a patient'"'"'s body, the method comprising the steps of:
-
(i) applying a pressure, substantially less than a systolic pressure, to said portion in a manner to provide even pressurization thereof;
(ii) applying sensor means to a measurement location within the pressed portion, the sensor means being capable of applying an external field to said measurement location, detecting a response of the measurement location to said external field indicative of blood-related signals, and generating dam representative thereof.
