First Claim
Patent Images
1. A sensor wrap for removably securing an emitter and detector circuit assembly of a pulse oximetry sensor to body tissue of pulsing blood, the sensor wrap comprising:
- a center tape portion configured to position an assembled reusable emitter and detector circuit assembly of a pulse oximetry sensor;
a securing tape portion extending from the center tape portion and configured to removably secure the sensor wrap proximate to body tissue carrying pulsing blood; and
a foldable portion including an attached side and a free side, wherein at least a portion of the attached side is attached to the center tape portion and the free side is configured to, before application of the sensor wrap to the body tissue, fold over the emitter and detector circuit assembly when the emitter and detector circuit assembly are positioned within the center tape portion to affix the emitter and detector circuit assembly between the center tape portion and the foldable portion, thereby forming an assembled sensor capable of removably securing the emitter and detector circuit assembly proximate the body tissue carrying the pulsing blood.

8. A sensor wrap including a foldable tape for positioning elements of a sensor within the sensor wrap before application of the sensor wrap to a measurement site thereby properly positioning the elements of the sensor with respect to one another, and eventually with respect to the measurement site on body tissue carrying pulsing blood, the sensor wrap comprising:
-
a base tape comprising a positioning portion which receives an assembled circuit assembly including an assembled emitter and an assembled detector;
a foldable tape attached to the base tape, wherein the foldable tape folds over the assembled circuit assembly before application of the sensor wrap to a measurement site, thereby removably securing the assembled circuit assembly within the sensor wrap; and
a fastener which removably secures the sensor wrap to the measurement site. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
