[0001] The invention relates to the field of medical devices, in particular to an obstetrics and gynecology hemostatic bag. Background technique

[0002] In clinical obstetrics and gynecology, postpartum hemorrhage is the most common complication, and any hemodynamic instability after delivery is defined as postpartum hemorrhage. At present, the commonly used treatment methods are uterine cavity gauze filling and uterine cavity water bag filling. The process of uterine cavity filling takes a long time, and the pain stimulation to the parturient is severe. It is difficult for patients to bear it under non-anesthesia state, and vaginal packing The procedure cannot avoid gauze contamination, which greatly increases the risk of intrauterine infection. Due to the relaxation of the cervix after delivery, the water sac in the uterine cavity is easy to slip out, resulting in the failure of compression and hemostasis, and the expansion of the water sac is uniform, an...
