The invention discloses a balloon hemostasis expander, which comprises a drainage cavity, an infusion cavity, a balloon, drainage holes, scale lines, a check valve and a Luer taper, wherein the drainage holes are formed in the front end of the drainage cavity; the Luer taper, which is arranged at the tail end of the drainage cavity, is connected to a drainage device; the scale lines are arranged on the tube wall of the drainage cavity; the front end of the infusion cavity is embedded in the tail end in the tube wall of the drainage cavity and is separated from the drainage cavity, so that an independent compartment is defined; the balloon communicates with the front end of the infusion cavity; and the check valve is arranged at the tail end of the infusion cavity. According to the balloon hemostasis expander provided by the invention, by arranging the drainage cavity, the infusion cavity, the balloon, the drainage holes, the scale lines, the check valve and the Luer taper which are cooperated, precise localization can be implemented by doctors; blood drainage in a uterine cavity can be completed while hemostasis is implemented, so that time and labor are saved, and working difficulty of the doctors is reduced; and the balloon hemostasis expander is suitable for promotion and application.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon hemostatic dilator. Background technique [0002] Postpartum hemorrhage is called postpartum hemorrhage if the amount of bleeding exceeds 500mL within 24 hours after delivery, and 80% of them occur within 2 hours after delivery. Postpartum hemorrhage is a serious complication during childbirth and one of the four leading causes of maternal mortality. Postpartum hemorrhage has always been the first cause of maternal death in my country in recent years, especially in remote and backward areas. The incidence of postpartum hemorrhage accounts for 2% to 3% of the total number of deliveries. In addition, gynecological abortion and birth control surgery are prone to gynecological hemorrhage. Due to the subjective factors of measuring and collecting the amount of bleeding, the actual incidence is higher. [0003] The causes of postpartum hemorrhage are uterine atony, ...
