Outline of Final Research Achievements

We found retained surgical gauze while creating several types of surgical gauze detection devices and surgical gauze for detection and detecting eddy current of metallic fiber included in the surgical gauze for detection. Actually, metallic fiber were included in surgical gauze and the change of eddy current was detected from the outside of the body before closing incisions, and the presence or absence of remnant gauze was verified. With respect to silver, the search for degradation kinetics in Both quantitative results of metallic element (silver) and pH change of the extract were very small, and it was judged that the influence of silver itself on the human body was extremely small. Considering biocompatibility, metallic resistance, actual detection distance, and decomposition dynamics in simulated environment of silver in the body, at present, it is necessary to set 4 or 16 circular sections (closed loop windings 3 to 7 times) of silver fibers.
