Detecting leakage from an internal surgical site

摘要

A leakage detecting implant can detect leakage of body fluid from an incision, resection, or other internal surgical site in a subject. The leakage detecting implant can include: one or more biodegradable colorant members having a tissue-contacting inner surface and an opposite outer surface; a resilient member having an inner surface coupled to the outer surface of the one or more colorant members; and a cover member having a body with an internal chamber and an opening on a tissue-contacting side, the internal chamber containing the resilient member and at least a portion of the one or more biodegradable colorant members with the tissue-contacting inner surface exposed through the opening, the cover member having an inner surface of the internal chamber coupled to an outer surface of the resilient member, the tissue-contacting side having one or more affixation surfaces adapted to be affixed to tissue of a subject.

1. An internal leakage detecting implant for detecting leakage from an internal surgical site comprising:
one or more biodegradable colorant members having a tissue-contacting inner surface and an opposite outer surface; a resilient member having an inner surface coupled to the outer surface of the one or more biodegradable colorant members; and a cover member having an elongate fluid-impermeable body with an internal chamber and an opening on a tissue-contacting side adapted to be placed over an internal surgical site in a tissue, the internal chamber containing the resilient member and at least a portion of the one or more biodegradable colorant members with the tissue-contacting inner surface exposed through the opening, the cover member having an inner surface of the internal chamber coupled to an outer surface of the resilient member, the tissue-contacting side having one or more affixation surfaces adapted to be affixed to tissue of a subject, wherein the fluid-impermeable body provides a fluid-tight seal when the one or more affixation surfaces are affixed to the tissue so that the opening is over the internal surgical site in the tissue to exposed the one or more biodegradable colorant members to the internal surgical site.
