Uterine cavity hemostatic component for postpartum women

Abstract

The invention discloses a uterine cavity hemostatic component for postpartum women. The hemostatic component includes a hemostatic balloon, the hemostatic balloon includes a balloon, a blood drainagetube and a liquid injection tube communicating with the balloon, the balloon is fixed on the blood drainage tube, the tail end, far away from the balloon, of the blood drainage tube is provided with an opening, the upper end of the blood drainage tube is provided with at least one through hole, and the liquid injection tube passes through the blood drainage tube and passes out from the side wall of the tail end of the blood drainage tube; and the hemostatic component is characterized by further including a fixing device, the fixing device is arranged on the part, located under the balloon, ofthe blood drainage tube, and the fixing device includes a supporting ring for lifting a uterus and sealing a cervix. Under the lifting action of the supporting ring, the cervix is placed in the middlepart of the supporting ring, so that the supporting ring has the effect of squeezing the cervix inward, and the balloon in the uterus cannot slide out from the cervix; and the supporting ring shrinksthe cervix to prevent blood from flowing into a vagina through the cervix, and the hemostatic component is convenient for observation and operation.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a uterine cavity hemostatic component for postpartum women. Background technique [0002] At present, the most widely used balloon for hemostasis of postpartum hemorrhage is Bakri's COOK balloon, which can be used for patients with postpartum hemorrhage during normal delivery and cesarean section. A hemostatic balloon is placed in the uterine cavity. The hemostatic balloon generates a hydrostatic pressure from the uterine cavity to the outside of the uterine cavity. This pressure is greater than the uterine artery pressure. Arterial access can effectively reduce postpartum uterine bleeding. [0003] The structure of the hemostatic balloon is similar to that of a urinary catheter. There is an inner balloon on the top of it, which can be fixed in the uterus after inflation, against the cervix, allowing blood to flow in from the upper end of the inner balloon, and then exit through ...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the cervix cannot contract naturally and the opening is too large, the balloon can easily fall off to the vagina after being filled with water, and the balloon cannot be fixed in the preset position correctly

[0006] 2. Because the balloon cannot completely block the uterine opening, the blood in the uterus will flow into the vagina, and after the parturition is completed, there may be a gap at the opening of the vagina (perineum), which needs to be sutured. If there is blood at this time Outflow will block the field of vision, and the operating position will be exposed and blurred

[0009] 1. Gauze is water-absorbent and easy to absorb blood, which makes it impossible for medical staff to estimate the amount of bleeding

[0010] 2. When using gauze to block, it is easy to leave the gauze in the patient's body, causing medical accidents and causing danger to the patient

The gauze may cause secondary trauma to the vagina, causing abrasions or lacerations, and the gauze is stuffed and compresses the urethra, so a catheter needs to be placed at the same time
