Abstract

The invention relates to the field of obstetrical instruments, and particularly discloses a uterine cavity hemostasis device and a uterine cavity hemostasis system. The uterine cavity hemostasis device comprises a catheter, a first balloon and a second balloon, wherein the distal end of the catheter is used for being inserted into a uterine cavity, the first balloon and the second balloon are both fixed at the distal end, the second balloon is sleeved on the first balloon, a gap between the second balloon sleeve and the first balloon is used for forming a medicine cavity to accommodate medicines, and a plurality of micropores communicated with the medicine cavity are uniformly distributed on the surface of the second balloon. Therefore, a plurality of micropores communicated with the medicine cavity are uniformly distributed on the surface of the second balloon, so that the medicine between the second balloon and the first balloon enters the bleeding position of the uterine cavity through the micropores under the extrusion of the expansion of the first balloon, the medicine can be ensured to contact any bleeding area on the inner wall of the uterine cavity, and the hemostatic effect of the uterine cavity is ensured.

Description

Uterine cavity hemostasis device and uterine cavity hemostasis system [ Field of technology ] The invention relates to the related field of obstetrical surgical instruments, in particular to a uterine cavity hemostasis device and a uterine cavity hemostasis system. [ Background Art ] The method is characterized in that a pregnant woman is provided with a uterine cavity, a uterine cavity is filled with sliver by compression hemostasis measures adopted in the early stage, the sliver is adhered to the wound surface due to the fact that fine scraps of the sliver are easy to adhere to the uterine wall, in addition, the uterine cavity is not uniform in tightness due to uneven stress during filling of the sliver, the sliver is filled in the uterine cavity to stop bleeding, the time consumption is quite long, pain is heavy, the hemostatic effect is difficult to bear by a patient in a non-anesthetized state, the sliver cannot be avoided from being contacted with vagina to pollute the sterile sliver if the sliver is filled in the vagina, the risk of infection of the uterine cavity is increased, the existing simple water sac is used for treating the uterine cavity to be improved, the defects of fewer functions and insufficient reliability are still caused, a plurality of problems and risks of postpartum uterine bleeding still exist, such as postpartum cervical slackening, water sac in the uterine cavity is easy to slide out, the condition inside and outside the uterine cavity cannot be monitored, the compression hemostasis failure is caused, the medical effect cannot be directly applied, the defect of the prior art can be overcome, the life safety factor of a puerperal is endangered, and the puerperal woman can still exist, and the medical treatment needs to be rapidly carried out by adopting a plurality of auxiliary medical measures, and the medical measures to achieve the effect simultaneously. The prior patent CN106491175A provides a disposable hemostatic administration bag belt for compressing uterine cavity. In this scheme, hemostatic medicine is injected through the top capsule top administration tube orifice, however, after the balloon is tightly attached to the uterine cavity wall, the hemostatic medicine may not or hardly flow to the bleeding area of the uterine cavity, resulting in poor hemostatic effect.
