b, the uterus is filled with a hemostatic balloon and sent into the uterine cavity through the cervical orifice;

step C, connecting the drainage bag 231 to the lower end of the drainage tube 23, and regularly recording the uterine cavity bleeding amount;

step D, injecting physiological saline into different capsule bodies according to the bleeding part of the uterus 3;

and E, monitoring the bleeding condition of the uterus 3 at any time after the balloon is placed, and taking out the balloon after bleeding stops.

Preferably, in the step B, when the hemostatic balloon for filling the uterus is delivered into the uterine cavity through the cervical orifice, the balloon placement position needs to be ensured to be accurate, and the specific method comprises the following steps: slowly sending the saccule into the uterine cavity from the cervical orifice, and stopping pushing inwards when pushing resistance is sensed, namely the end part of the drainage tube 23 is just abutted against the top of the uterus 3; because the length of the part of the upper end of the drainage tube 23, which extends out of the body cavity bag 11, is 5-8mm, the length of the exposed section is designed according to the structure of the uterus 3, so that when the end part of the drainage tube 23 is just abutted against the top of the uterus 3, the body cavity bag 11 is just pressed on the lower section of the uterus 3, and meanwhile, the two uterine horn bags 12 are just positioned at the uterine horns 31.

At the moment, according to the numerical condition of the compression point, the uterine contractility condition can be objectively and accurately evaluated, the times of vaginal examination are reduced, the risk of infection is reduced, the delivery experience is improved, and the perinatal period ending is improved.

According to the numerical value of the sub-pressure at each point recorded in the display, when the contraction force of the uterus 3 after delivery reaches 350-.

Therefore, in the process, the pressure sensors are used for monitoring the contraction force of the uterus 3 and the contraction forces of the uterine horns 31 on the two sides in a combined manner, so that the bleeding condition can be monitored in real time, the balloon is taken out after 24 hours, the bleeding condition can be timely mastered if the balloon can be monitored in real time, the balloon does not need to wait for 24 hours, and the balloon can be withdrawn as required after bleeding stops. Shortening the treatment time and reducing the patient's pain (if there is no recorded compression point value, it is necessary to frequently check uterine contractions, or to press the fundus from the abdominal wall, but with poor accuracy, or to massage the uterus from the vaginal examination, the parturient is very uncomfortable and increases the chance of infection).

Moreover, the pressure sensor is used for real-time monitoring, so that the bleeding condition can be analyzed in time, the treatment scheme can be adjusted in time, the delay of the illness state can be prevented, the patient can be treated effectively in a targeted manner, the diagnosis and treatment in the next step can be guided, and the treatment effect can be improved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
