An on-duty EMT in the late stages of pregnancy was hospitalized after a drunk patient punched her in the stomach, police said Monday.

The 32-year-old EMT was treating a drunk man outside Solomon & Kuff Rum Hall on 12th Avenue in Harlem around 3:30 a.m. Sunday for a cut to his wrist and intoxication.

When the woman — who police sources said was in the “late stage” of pregnancy — told her patient he needed to go to the hospital, he flew into a fit of rage — punching her in the stomach before running off, cops said.

The EMT was taken to Mount Sinai Hospital with non-life threatening injuries. Her attacker is still on the loose, cops said.
