[0002] Postpartum hemorrhage is a common and serious complication of childbirth, and has always been the focus of obstetric medical staff. At present, the clinical diagnosis and treatment process of postpartum hemorrhage is very clear, and the treatment speed and success rate are also high. However, the common problem is that the measurement of postpartum hemorrhage is inaccurate and the estimation is insufficient, which cannot provide an accurate basis for clinical blood transfusion and related rescue measures, resulting in delays in the best time for treatment and adverse consequences. Therefore, accurate measurement of postpartum hemorrhage is of great significance for the judgment and treatment of clinical medical staff.
[0003] The commonly used clinical method for measuring postpartum hemorrhage is the blood basin method, but the pelvic volume of the blood basin is generally 400mL, which is limited. When the amount of bleeding is large, it will overflow from the blood basin, which is not only impossible to measure accurately, but also causes blood leakage to pollute the surgical environment and may even cause bacteria to contaminate the operating room. At the same time, nursing staff are required to clean it up, which brings extra workload to medical staff. Moreover, the horizontal surface area of the blood basin is large, and the height direction is equal thickness, making it difficult to accurately estimate the amount of bleeding.
