Breakage of surgical latex gloves during surgery is a serious problem for prevention of infection. Various factors are involved in the occurrence of breakage, and the size of pinholes varies accordingly. Accurate measurement of high impedance is necessary for detection of pinholes of small sizes. In order to detect pinholes in gloves immersed in solutions with high accuracy, we have established an accurate method for measurement of electric impedance without leakage current on the surface of latex gloves. Using DC, we measured by this method the electric impedance of 5 kinds of surgical latex gloves that were kept still, and found that the impedance remained high at about 200 MΩ over a period of 17 hours, indicating the absence of pinholes under these conditions.
