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 o

Embodiment 1

[0036] Such as figure 1 , 7 As shown, it is the first embodiment of the uterine cavity 8 hemostatic assembly for postpartum women in this application.

[0037] A uterine cavity 8 hemostatic assembly for postpartum women, including a hemostatic balloon and a fixing device, the hemostatic balloon includes a balloon 1, a blood drainage tube 2, and a liquid injection tube 3 communicating with the balloon 1, and the balloon 1 is fixed on the On the blood drainage tube 2, the end of the blood drainage tube 2 away from the balloon 1 is provided with an opening, the upper end of the blood drainage tube 2 is provided with at least one through hole, and the liquid injection tube 3 passes through the blood drainage tube 2 and passes through the end of the blood drainage tube 2. The side wall pierces out.

[0038] The fixing device is arranged under the balloon 1, and the fixing device includes a support ring 4 for lifting the uterus and closing the cervical opening 7, and the support r...

Embodiment 2

[0042] Such as Figure 2-4 As shown, this embodiment is similar to Embodiment 1, the difference is that the fixing device also includes a funnel-shaped bracket 5, the support ring 4 is fixed above the bracket 5, and the bracket 5 is fixed on the outer wall of the blood drainage tube 2; In the embodiment, the bracket 5 provided at the bottom of the support ring 4 is relatively fixed with the blood drainage tube 2 .

[0043] The blood collection channel includes a plurality of arc-shaped holes 51 , and the arc-shaped holes 51 are arranged along the circumferential direction of the blood drainage tube 2 .

[0044] The bracket 5 is fixed with the blood drainage tube 2, and its advantage is: when the support ring 4 is fixed in the human body (between the inner side of the pubic arch and the posterior fornix of the vagina), the position of the bracket 5 is relatively fixed, and a certain support is generated for the blood drainage tube 2. Lifting effect, so that its position is fix...

Embodiment 3

[0053] Such as Figure 2-6 As shown, this embodiment is similar to Embodiment 2. In this embodiment, the support ring 4 and the bracket 5 can move up and down relative to the blood drainage tube 2, thereby adjusting the distance between the support ring 4 and the balloon 1, and the bracket 5 The bottom end is flexibly connected with the blood drainage tube 2, and its advantage is that the support 5 and the blood drainage tube 2 that are flexibly connected are suitable for puerperas with different heights and different distances between the uterine cavity 8 and the cervix. For puerperas with a large distance between the cervix, the support ring 4 and the bracket can be moved downwards to increase the distance between the support ring 4 and the balloon 1, so as to adapt to the puerpera who is taller and has a larger distance between the uterine cavity 8 and the cervix; For women who are taller and have a larger distance between the uterine cavity 8 and the cervix, the supporting...

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 ...
