Foldable sensor device and method of using same
First Claim
1. A sensor device comprising:
- a foldable member carrying one or more sensor elements;
a communications link configured to transmit data from said one or more sensor elements, the communications link including a lead coupled to a sensor element;
a frame engaging said foldable member, the frame including a material that is rigid relative to the foldable member, together said frame and foldable member adapted to be deformed from an initial shape into a customized form providing said one or more sensor elements in a desired orientation relative to a tissue field, with said frame maintaining said foldable member in said customized form; and
a stabilization component between a lead of said communications link and said one or more sensors elements wherein the stabilization component comprises a first aperture through said foldable member and disposed between said one or more sensor elements and said lead.

Abstract
A physiologic sensor device configured to be placed on an appendage. The sensor device includes a foldable portion designed to be deformed around the tip of the appendage. In some embodiments the foldable portion is a soft compressible material. In other embodiments a stabilization component is provided to isolate sensing elements from external forces. Some embodiments also include a deformable frame that folds in response to a bending force as the sensing device is placed on the appendage. The deformable frame holds the sensor device in place until another bending force is applied. In other embodiments the frame and/or sensor elements are removable and disposable relative to other components of the sensor device.

26. A method of attaching a foldable sensor device to an appendage comprising:
-
bending a deformable sensor device over an appendage portion so as to position optical sensor elements on either side of the appendage; biasing said sensor device in a bent position so as to retain said appendage portion within said sensor device;
wherein said biasing is performed by a rigid deformable frame engaging foldable material in contact with said appendage; andisolating said optical sensor elements with a stabilization component, said stabilization component transferring an external force to the appendage away from the optical sensor elements, wherein said isolating comprises inserting the appendage through a first aperture in the sensor device. - View Dependent Claims (27, 28, 29, 30, 31)
