Description

A pressure-adjustable uterine hemostatic balloon device

technical field

The invention relates to the technical field of obstetrics and gynecology medical devices, in particular to a pressure-adjusted uterine hemostatic balloon device.

Background technique

The hemostatic balloon is a therapy for postpartum hemostasis. The hemostatic balloon generates a hydrostatic pressure from the uterine cavity to the outside of the uterine cavity, which is greater than the uterine arterial pressure. The balloon after water injection directly acts on the middle and lower ends of the uterus. That is, the entrance of the uterine artery can effectively reduce the blood flow into the uterus. The operation of this therapy is relatively simple, takes less time, and can quickly stop bleeding. It is also easier to remove after surgery. Blood has a good control effect, especially for postpartum hemorrhage that occurs after vaginal delivery. At present, vaginal delivery is advocated to reduce the rate of cesarean section, and uterine balloon packing is a simple and effective method to treat natural postpartum hemorrhage.

However, most of the uterine hemostatic balloons in the prior art still have the following problems that need to be solved urgently: 1. There is no effective treatment and hemostatic measures for uterine horn bleeding: when the placenta is attached to the uterine horn, placental adhesion or placental adhesion is easy to occur. Retention, when the placenta is removed by hand or curettage, the amount of bleeding on the attachment surface of the placenta is large, because this part forms an angle with the uterine body cavity, the existing balloon cannot effectively compress the uterine horn, and the hemostatic effect is poor, and the amount of postpartum hemorrhage is large; 2 . During the operation, in the event of intrauterine adhesions, abnormal uterine cavity morphology (excessive anteversion or retroversion of the uterus), and narrow uterine cavity in the uterine body, the balloon is not easy to insert into the fundus of the uterus, and it is easy to break and slip out. The balloon head is wide, the silicone material is soft, and there is no supporting structure, so it is not easy to put in; 3. After the traditional uterine hemostatic balloon is placed, the doctor needs to pack gauze in the vagina to prevent the balloon from slipping and the uterine cavity. Blood flows out, however, gauze is absorbent and absorbs blood easily, making it impossible for medical staff to accurately measure the amount of bleeding, and may cause secondary trauma to the vagina when packing or removing vaginal gauze, causing abrasions or lacerations .

Therefore, we propose a pressure-adjustable uterine hemostatic balloon device.
