The invention provides a method and device for correcting uterine contraction pressure. The method for correcting uterine contraction pressure comprises the following steps: step 1, collecting uterine contraction pressure data in real time, detecting that whether pressure zeroing instructions are received or not at the current time, and skipping to the step 2 after the pressure zeroing instructions are received; step 2, carrying out processing and analysis on the uterine contraction pressure data before the pressure zeroing instructions are received, thus obtaining uterine contraction pressure correcting values; and step 3, replacing the uterine contraction pressure data before the pressure zeroing instructions are received with the uterine contraction pressure correcting values, and displaying the corrected uterine contraction pressure data. With the method and the device, the uterine contraction pressure data before pressure zeroing is corrected, so that the accuracy of the uterine contraction pressure data before pressure zeroing is guaranteed, the risk of misdiagnosis by a doctor is reduced, the repeated monitoring is avoided, thus the monitoring time and medical resources are saved, and the monitoring efficiency is improved.
