After the ice water is injected, the hemostatic bag expands and evenly compresses the endometrium, and the hemostatic effect can be produced when the pressure exceeds the vasoconstrictive pressure. Through pressure monitoring, you can know the changes of intrauterine pressure at any time. If there is a regular rise and fall of intrauterine pressure, it is the performance of the recovery of uterine spontaneous contraction; the low temperature of the ice pack can also stimulate the uterus to produce spontaneous contraction and play a hemostatic effect. If the monitoring shows that the temperature rises, the ice water can be replaced in time through the tee.

Compared with the prior art, the present invention has positive and obvious effects. The present invention integrates the pressure measuring and temperature measuring device with the elastic hemostatic bag, the shape of the elastic hemostatic bag is similar to that of the uterine cavity after expansion, the pressure inside the bag is displayed by the pressure device, the pressure is controlled within the safe range, and the pressure in the uterine cavity is uniform , Pressure exceeding arterial systolic pressure will inevitably produce hemostatic effect. Through pressure monitoring, the occurrence of spontaneous uterine contractions can be detected in time; through the temperature measuring device to display the change of water temperature, it is convenient to replace the ice water in time, so as to avoid the weakening of the hemostatic effect and maximize the hemostatic effect. It can be used in combination with other hemostatic methods to maximize the hemostatic effect and fundamentally reduce the rate of total hysterectomy and mortality. The present invention is easy to operate, intuitive to monitor, reduces bleeding to the greatest extent, and guarantees the life safety of patients.
