Abstract
Present embodiments include a remanufactured bandage-type medical sensor having an optical assembly with 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. The sensor also includes a laminate assembly having an electrically conductive adhesive transfer tape (ECATT) layer disposed over the photodetector, and the ECATT layer is adapted to shield the photodetector from electromagnetic interference (EMI). A nonconductive layer supports the emitter, the photodetector, and the ECATT layer within the sensor. At least a portion of the optical assembly is from a used bandage-type medical sensor, and at least a portion of the laminate assembly is new.
Claims20
A method of remanufacturing a used bandage-type medical sensor, comprising:
- obtaining the used bandage-type medical sensor, the used bandage-type medical sensor comprising an electrically conductive adhesive transfer tape (ECATT) layer adapted to shield a detector of the used bandage-type medical sensor from EMI;
- and
- replacing a used patient-contacting adhesive bandage layer of the used bandage-type medical sensor with a new patient-contacting adhesive bandage layer.
A remanufactured bandage-type medical sensor, wherein the remanufactured bandage-type medical sensor is formed by a process comprising:
- surrounding a detector of a used medical sensor with an electrically conductive adhesive transfer tape (ECATT) layer to shield the detector from electromagnetic interference (EMI);
- securing the ECATT layer to a nonconductive support layer;
- and
- disposing the nonconductive support layer around the detector.
A pulse oximetry sensor, comprising:
- an optical assembly having an emitter configured to transmit one or more wavelengths of light and a photodetector configured to receive the one or more wavelengths of light transmitted by the emitter;
- and
- an electrically conductive adhesive transfer tape (ECATT) layer disposed over the photodetector, wherein the ECATT layer is adapted to act as a Faraday shield for the photodetector, and the ECATT layer comprises a tape layer having a pressure-sensitive adhesive disposed on opposite sides and a conductive filler disposed in the adhesive.
