Abstract
Present embodiments include a bandage sensor having an electrically conductive adhesive transfer tape layer as a Faraday shield. The electrically conductive transfer tape layer may be used in lieu of a fully metallic Faraday shield. The present embodiments also include a sensor cable having one or more conductive polymer EMI/RFI shields in place of a fully metallic EMI/RFI shield. Methods for manufacturing and remanufacturing such sensors and cables are also disclosed.
Claims24
A patient monitoring system, comprising:
- a spectrophotometric sensor comprising:
- an optical assembly having an emitter adapted to transmit one or more wavelengths of light and a photodetector adapted to receive the one or more wavelengths of light transmitted by the emitter;
- and
- a laminate assembly having an electrically conductive adhesive transfer tape (ECATT) layer disposed over the photodetector, wherein the ECATT layer is adapted to reduce electromagnetic interference (EMI) experienced by the photodetector, and a nonconductive layer supporting the emitter, the photodetector, and the ECATT layer within the sensor.

A laminate assembly, comprising:
- a main nonconductive support layer having a first optical window, a second optical window, a first surface, and a second surface;
- an electrically conductive adhesive transfer tape (ECATT) layer disposed on the first surface of the main nonconductive support layer such that the ECATT layer surrounds at least the first optical window;
- an insulating layer disposed on the ECATT layer such that the ECATT layer is disposed between the insulating layer and the main nonconductive support layer and covers the first optical window;
- and
- a first release liner disposed over the insulating layer, the ECATT layer, and the main nonconductive support layer.
