Classification: A61B

Abstract:
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.
