Precisely adjustable pressure uterine hemostatic balloon device

Abstract

The invention discloses a pressure-precisely adjustable uterine hemostatic balloon device, which can squeeze the bleeding part of the uterus so that the loose cervix is ​​closed upwards, thereby preventing the hemostatic balloon from protruding from the cervix; The outflow of blood and the amount of blood accumulated in the uterine cavity drainage. The main points of the technical solution are: a pressure-accurately adjustable uterine hemostatic balloon device, which includes the existing liquid injection hemostatic component and liquid injection device, and also includes a cervical cover, which is arranged under the hemostatic balloon and has an air bag inside , a sliding channel is provided in the middle, the first drainage tube can move in the sliding channel, a limiting structure is provided between the sliding channel and the first drainage tube, and the cervical mask is detachably fixed on the outer wall of the first drainage tube through the limiting structure. After the air bag in the cervical mask is inflated, the cervical mask is stuck between the posterior fornix of the vagina and the inner side of the pubic arch, and the cervical mask is squeezed to the inner side of the cervix, so that the cervix tends to close; the cervical mask also has a drainage hole , second drainage tube and collection bag.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a precisely pressure-adjustable uterine hemostatic balloon device. Background technique [0002] The existing uterine hemostatic balloon is applied to patients with postpartum hemorrhage during normal delivery or cesarean section. The hydrostatic pressure from the inside to the outside of the uterine cavity is greater than the pressure of the uterine artery. The balloon after water injection directly presses the inner wall of the middle and lower end of the uterus, that is, the entrance of the uterine artery, which can effectively reduce postpartum uterine bleeding. At the same time, the balloon can also compress the open blood sinus where the placenta attaches to the endometrium, further reducing uterine bleeding. [0003] The structure of the hemostatic balloon is similar to setting a balloon on the top of the urinary catheter. After the balloon is inflated, it can be fixed in t...

AI Technical Summary

Problems solved by technology

[0005] 1. Because the cervix is ​​loose and the opening is too large, the balloon can easily slip into the vagina after being filled with water, and the balloon cannot be properly placed in the uterine cavity

[0006] 2. Since the balloon cannot completely block the cervix, the blood in the uterus will also flow into the vagina, and after delivery, there may be incisions or lacerations in the vaginal wall and perineum, which need to be sutured. Occasionally, blood will flow out, which will block the surgical field and affect the operation

[0008] 1. Gauze is water-absorbent and easy to absorb blood, which makes it impossible for medical staff to accurately measure the amount of bleeding

[0009] 2. Since the intrauterine bleeding is absorbed by the gauze in the vagina, it is impossible to accurately judge the hemostatic effect of the intrauterine hemostatic balloon

[0010] 3. When packing or taking out the vaginal gauze, it may cause secondary trauma to the vagina, causing abrasions or lacerations, and the gauze will compress the urethra and intestinal tract after packing, affecting urination and defecation
