Noninvasive oximetry optical sensor including disposable and reusable elements
First Claim
1. A disposable portion of a noninvasive optical oximetry sensor, the sensor capable of attaching to a tissue site and providing signals usable by an oximeter, the signals being indicative of light attenuated by body tissue at the tissue site and including sufficient information for the oximeter to determine one or more physiological parameters of the body tissue including at least one of oxygen saturation or pulse rate, the disposable portion comprising:
- a first layer;
a plurality of attachment mechanisms matable with structural members of a reusable portion of said sensor, the reusable portion including at least one light source and at least one detector, each attachment mechanism including a top protruding member and a base extending substantially perpendicular to the top member, wherein when the attachment mechanisms are mated with the structural members, at least one of the structural members can move with respect to a corresponding one of said attachment mechanisms to allow self-adjustment between the disposable portion and the reusable portion when the disposable portion is applied to a patient after sensor assembly; and
a second layer sandwiching the bases of the attachment mechanisms between the first layer and the second layer.

Abstract
A pulse oximetry sensor includes reusable and disposable elements. To assemble the sensor, members of the reusable element are mated with assembly mechanisms of the disposable element. The assembled sensor provides independent movement between the reusable and disposable elements.

9. A method of assembling a noninvasive optical oximetry sensor, the method comprising:
-
providing a disposable element of the sensor including a plurality of attachment mechanisms matable with structural members of a reusable element of the sensor, each attachment mechanism including a base flange configured to mount with respect to said disposable element, wherein when the attachment mechanisms are mated with the structural members, at least a portion of the structural members of the reusable element moves with respect to at least a portion of a corresponding attachment mechanism of the disposable element to reduce stretching forces exerted on the reusable element during attachment of the sensor to a measurement site; and combining said reusable element with said disposable element by mating the attachment mechanisms with the structural members. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A noninvasive optical sensor comprising:
-
a tape assembly removably attachable to a measurement site of a patient, the tape assembly configured to bend around a digit of a patient when attached to form an inner radius of the sensor around the digit; a plurality of connectors positioned by said tape assembly around said inner radius; and a reusable assembly including an emitter portion, a detector portion, and a plurality of matable connectors configured to mate with the plurality of connectors positioned by said tape assembly, wherein when the matable connectors mate with said connectors and the reusable assembly is bent around the digit of the patient by application of the tape assembly to a digit, the reusable assembly forms an outer radius of the sensor larger than said inner radius causing at least some of the matable connectors to mate with said connectors of said tape assembly, said matable connectors mating with said connectors forming a mechanical lock until said reusable assembly is no longer bent around said digit. - View Dependent Claims (17)
