Pressure-precision adjustable uterus hemostasis balloon device

Abstract

The invention discloses a pressure-precision adjustable uterus hemostasis balloon device which can extrude a uterus bleeding part and make a slack uterus neck opening close upwards so as to prevent ahemostasis balloon from coming off the uterus neck opening; and the device can also collect two pieces of data including a volume of blood drained from a uterus neck and a volume of hematocele drainedfrom the uterus neck. The technical scheme is characterized in that the pressure-precision adjustable uterus hemostasis balloon device comprises an existing liquid injection and hemostasis componentand a liquid injection device and also comprises a uterus neck cover, wherein the uterus neck cover is disposed under the hemostasis balloon and provided with an airbag inside, a slide channel is disposed at the center, a first drainage pipe can be moved on the slide channel, a limiting structure is disposed between the slide channel and the first drainage pipe, and the uterus neck cover is fixedon the outer wall of the first drainage pipe by the limiting structure in a dismountable manner. The airbag inside the uterus neck cover can realize clamping of the uterus neck cover between a vaginaposterior fornix and the inner side of an arcus pubis after being inflated, and the uterus neck cover is extruded to the inner side of the uterus neck opening, so that the uterus neck opening tends tobe closed; and the uterus neck cover is also provided with a liquid drainage hole, a second drainage pipe and a 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
