The invention belongs to the technical field of fetal heart monitors, and discloses an intelligent medical fetal heart monitor which comprises a monitor body, a movable shielding assembly, a rotating assembly and a fixing assembly, a connecting line is connected to the monitor body, a fetal heart monitoring probe is installed at the outer end of the connecting line, an opening is formed in the top end of the monitor body, a top cover is installed at the top end of the monitor body, fastening screws are symmetrically connected to the front wall and the rear wall of the top cover in a screwed mode, the two ends of the top cover protrude outwards to the front side and the rear side of the monitor body respectively, and first grooves are formed in the two ends of the lower surface wall of the top cover. According to the invention, by forming the opening in the top end of the monitor body, adding the top cover with the first grooves, and clamping the end face of the shell of the monitor body into the first grooves, a top cover fixing column can be fixed, during large overhaul, only the top cover needs to be pulled upwards and taken down, the top end is provided with a large overhaul area, shielding is little, and follow-up rapid maintenance by people is facilitated.
