Reprocessing of a physiological sensor
First Claim
1. A method for reprocessing a previously used physiological sensor, the sensor including a plurality of physiological sensor components and a cable component, the method comprising:
- determining a physiological sensor component of the plurality of physiological sensor components is to be replaced, wherein the physiological sensor component to be replaced does not comprise all of the plurality of physiological sensor components or the entire physiological sensor;
detaching the physiological sensor component to be replaced from the cable component;
determining that a replacement physiological sensor component operates within a specification of the physiological sensor; and
splicing a wire portion extending from the replacement physiological sensor component to the cable component to form a reprocessed physiological sensor.

Abstract
Because reprocessing or refurbishing of physiological sensors reuses large portions of an existing sensor, the material costs for refurbishing sensors is significantly lower than the material costs for making an entirely new sensor. Typically, existing reprocessors replace only the adhesive portion of an adhesive physiological sensor and reuse the sensing components. However, re-using the sensing components can reduce the reliability of the refurbished sensor and/or reduce the number of sensors eligible for refurbishing due to out-of-specification sensor components. It is therefore desirable to provide a process for refurbishing physiological sensors that replaces the sensing components of the sensor. While sensing components are replaced, generally, sensor cable and/or patient monitor attachments are retained, resulting in cost savings over producing new sensors.

14. A reprocessed physiological sensor comprising:
-
a wire portion; a physiological sensor component coupled to the wire portion, wherein the wire portion is configured to communicate signals to and/or from the physiological sensor component, and wherein the physiological sensor component is not a replacement physiological sensor component; a replacement physiological sensor component also coupled to the wire portion, wherein the wire portion is further configured to communicate signals to and/or from the replacement physiological sensor component; and a used cable component including; at a first end, a monitor connector; and at a second end from which a previously used physiological sensor component was cut, a new attachment to the wire portion, wherein; the replacement physiological sensor component is a replacement for a previously used physiological sensor component, a performance of the previously used physiological sensor component has been determined to not satisfy a threshold, and a performance of the replacement physiological sensor component has been determined to meet a specification of the reprocessed physiological sensor. - View Dependent Claims (15, 16, 17, 18)
