Disposable PH test paper diagnosis rod for early broken fetal membranes

The utility model discloses a disposable caul early rupture pH test paper diagnostic stick, comprising a stick, wherein one end of the stick assumes ellipsoidal shape, the surface of the ellipsoid covers a coat of pH test paper, and the other end of the stick assumes flat shape. The head of the diagnostic stick can directly and conveniently spread to the cervical orifice or the inner orifice.
