Abstract

The invention relates to a uterine filling balloon catheter. The uterine filling balloon catheter is composed of a catheter (1), a uterine balloon (2), a drainage cavity (11) and one-way valves (10).According to the invention, a red clay layer, a nano-chitosan molecular sieve layer and a quaternary phosphonium salt antibacterial layer are compounded on the surface of the uterine balloon, and thehemostatic effect of the uterine balloon is greatly improved through the compounding, so that the uterine filling balloon catheter provided by the invention has an excellent application prospect.

Description

【Technical field】 [0001] The invention belongs to the technical field of medical equipment. More specifically, the present invention relates to a uterine tamponade balloon catheter. 【Background technique】 [0002] Worldwide, more than half a million women die each year from complications related to pregnancy and childbirth. Studies have shown that severe postpartum hemorrhage is the leading cause of maternal morbidity and mortality worldwide. Severe postpartum hemorrhage is also the main cause of maternal death in my country, accounting for 28% of the total number of maternal deaths in the country. In obstetric hemorrhage, postpartum hemorrhage is the most common, and its main causes are uterine atony, placental factors, soft birth canal injury and coagulation dysfunction. In addition, serious complications of postpartum hemorrhage are hemorrhagic shock, disseminated intravascular coagulation, anemia, etc. [0003] Treatment methods for postpartum hemorrhage include cons...
