The medical protective mask comprises a mask body, two transverse side ends of the mask body are respectively connected with an elastic band, the two elastic bands are symmetrically arranged relativeto the longitudinal central axis of the mask body, a nose clamping strip is arranged on the upper portion of the mask body, and a carbon dioxide monitoring opening is formed in the upper portion of the nose clamping strip. Two air holes are further formed in the mask body, and elastic sealing rings are concentrically and fixedly arranged on the air holes. By means of the structure, a patient is effectively isolated from external air through the mask, external air possibly carrying pathogenic bacteria cannot enter the respiratory system of the patient through the gap of the mask, exhaled air ofthe patient is exhausted after being filtered through the mask, and therefore safety of the patient and safety of medical staff are guaranteed, and cross infection in a hospital is prevented.
