Finger sleeve sensor holder
First Claim
1. A medical sensor holder for positioning a medical sensor relative to a patient appendage, comprising:
- an appendage engaging member to which a medical sensor may be selectively connected, said member being plastically deformable to a first shape, wherein said member is also elastically deformable from said first shape to a second shape, and wherein said elastic deformation between said first shape and said second shape provides a resilient retaining force for selective use in attaching said member to an appendage.

Abstract
A conformable medical sensor is provided that has particular applicability for positioning a pulse oximeter sensor relative to a patient appendage. In one embodiment, the sensor holder includes a patient engaging member that is plastically deformable to permit the sensor holder to be conformed to the patient appendage, and plastically deformable to provide a retention force relative to the patient appendage. For example, the engaging member may be bent into a first shape that disposes first and second portions of the sensor holder into an opposing relationship the for receiving a patient appendage therebetween. Once deformed, the engaging member may be elastically deformed to a second shape to provide a retention force so as to maintain the sensor holder and a sensor interconnected thereto in contact with the patient appendage. In another embodiment, and the sensor holder may include a deformable backing layer that is plastically and elastically deformable, as described above, together with a patient interface layer having a recess located for the receipt of the sensor therein.

8. A method for positioning a medical sensor relative to a patient appendage, said method comprising the steps:
-
interconnecting a medical sensor to an appendage engaging member;
plastically deforming said appendage engaging member to a first shape, wherein first and second portions of said engaging member are disposed in a spaced opposing relationship;
elastically deforming said appendage engaging member from said first shape to a second shape, wherein said first and second portions are elastically deflected relative to one another causing a resilient restoring force therebetween;
inserting a patient appendage between said first and second portions while said engaging member is in said second shape; and
utilizing said resilient restoring force to apply a compressive force to said appendage. - View Dependent Claims (7, 9, 10, 11)
