Problems solved by technology

However, postpartum uterine contraction is weak and the uterus is soft and floating, resulting in no force point for this pressure. Clinically, the vagina is filled with gauze at the posterior fornix of the uterus to provide support. This force is unreliable and affects rectal and bladder functions; Enhanced hemostasis also requires use of an elastic girdle over the abdomen

Embodiment 1

[0063] Example 1: postpartum hemorrhage uterine hemostat,

[0064] The implementation mode of this embodiment is as follows:

[0065] The uterine hemostat mainly includes a truncated cone suction cup 1, an air suction tube 2, a three-lumen tube 3, a self-sealing air suction tube connector 4, a uterine catheter 5, a self-sealing uterine catheter connector 6, an intrauterine balloon 7, a balloon Catheter 8 and balloon catheter self-sealing joint 9;

[0066] The intrauterine balloon 7 is located within the truncated conical suction cup 1 and exceeds the upper edge of the truncated conical suction cup 1; the intrauterine fluid sac 7 is an elastically expandable sphere with a volume of 600ml.

[0067] The cross section of the truncated cone suction cup 1 is circular, its depth is 20mm, the bottom circle diameter is 50mm, and the top circle diameter is 3 times of the bottom circle diameter.

[0068] When the cross section of the truncated conical suction cup 1 is circular, the con...

Embodiment 2

[0074] Example 2: Uterine hemostasis device for postpartum hemorrhage

[0075] The implementation of this embodiment is the same as that of Example 1, except that the intrauterine balloon 7 is an oval spheroid with a volume of 500ml; the cross-section of the truncated cone suction cup 1 is circular, and its depth is 80mm, The bottom circle diameter is 120mm, the top circle diameter is 1.5 times of the bottom circle diameter; is 1 / 5 of the diameter of the bottom circle. Uterine catheter 5 is a uterine drainage tube. The uterine hemostat is made of silicone material.

Embodiment 3

[0076] Example 3: Uterine hemostasis device for postpartum hemorrhage

[0077] The implementation of this embodiment is the same as that of Example 1, except that the intrauterine fluid bag 7 is an elastically expandable sphere with a volume of 800ml; the cross section of the truncated cone suction cup 1 is circular, and its depth is 120mm , the diameter of the bottom circle is 80mm, and the diameter of the top circle is 5 times of the diameter of the bottom circle; The distance is 1 / 8 of the diameter of the bottom circle. The intrauterine catheter 5 is an intrauterine administration tube. The uterine hemostat is made of polycarbonate material.

Abstract

The invention relates to an uterus hemostat for postpartum hemorrhage. The uterus hemostat for postpartum hemorrhage mainly comprises a truncated cone-shaped sucker 1, an air extraction tube 2, a three-channel tube 3, a self-sealing air extraction tube joint 4, an intrauterine catheter 5, a self-sealing intrauterine catheter joint 6, an intrauterine balloon 7, a balloon catheter 8 and a balloon catheter self-sealing joint 9. According to the invention, a hemostatic balloon and a uterus external sucker are placed in the uterus with postpartum hemorrhage to realize a uterus external supporting effect; therefore, the hemostatic effect of the traditional balloon is improved; the uterus hemostat for postpartum hemorrhage can preferably and more reliably work.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of medical equipment. More specifically, the present invention relates to a uterine hemostat for postpartum hemorrhage. [0003] 【Background technique】 [0004] Postpartum hemorrhage is a serious obstetric complication and the main cause of maternal mortality. The current international and domestic guidelines on the treatment of postpartum hemorrhage all propose the use of uterine cavity balloon tamponade, especially postpartum hemorrhage that occurs after vaginal delivery. Bakri balloon is a uterine tamponade professionally used for postpartum hemorrhage. It has been used for more than 20 years, and a large number of literature reports have confirmed its curative effect and non-invasiveness. [0005] The main principle of the Bakri balloon is that the balloon directly compresses the uterine wall to stop bleeding: the causes of postpartum hemorrhage are mostly "placenta previa" and "scarred uterus"...
