Description

Hemostatic bag for preventing uterine water bag from slipping Technical Field The utility model belongs to the field of medical supplies, and particularly relates to a hemostatic bag for preventing uterine water bags from slipping. Background At present, a method for filling a balloon (namely a hemostatic balloon) into a uterine cavity is generally adopted for a puerpera with uterine bleeding at the lower uterine segment after a caesarean section or vaginal delivery in clinic, the conventional uterine cavity balloon is required to enter the uterine cavity, and then the balloon is injected with water or inflated, so that the circumferential wall of the balloon is in extrusion contact with the inner wall of a uterine cavity channel after the balloon is inflated, and further the aim of hemostasis is achieved. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide the hemostatic bag for preventing the uterine water bag from slipping, and solves the problem that the hemostatic bag is easy to slip from the uterine cavity in the prior art. The aim of the utility model can be achieved by the following technical scheme: a hemostatic sac for preventing uterine water sac from slipping, comprising a circular sac body; The inner part of the bag body is provided with a cavity for containing liquid, and the bag body is made of elastic materials; the water injection pipe is connected with the inner cavity of the bag body and is communicated with the cavity of the bag body, and the water injection pipe is provided with a switch valve; the inside a plurality of elastic rods that are annular evenly distributed that are equipped with around the cell body central axis of cell body, the elastic rod can carry out elastic bending, and the elastic rod is coaxial to placing with the cell body central axis, and elastic rod one end is all fixed with the inside inboard perisporium that is close to cell body central axis one end of cell body inside.
