Description

Anti-blocking uterus hemostasis device

Technical Field

The application relates to the technical field of postpartum uterine hemostasis, in particular to an anti-blocking uterine hemostasis device.

Background

Postpartum hemorrhage is generally defined as the loss of at least 500 milliliters of blood within 24 hours of delivery, and the inability to control postpartum hemorrhage may require women to receive multiple blood transfusions and, in severe cases, complete hysterectomy. Postpartum hemorrhage may be caused by the causes of uterine contractility, birth canal injury, placenta retention, coagulopathy and the like. Uterine contractions are the most common cause of hypodynamia or postnatal uterine contractions. Normally, uterine smooth muscle fibers shrink after delivery and shrink the blood vessels that serve the placenta bed. If the uterus is not contracted normally after delivery, these blood vessels are exposed in the uterine cavity, resulting in uterine bleeding. The uterine contractility may be caused by prolonged labor, prolonged use of uterine contractility stimulants, excessive uterine distension, infection, placenta abnormality or bladder distention. Postpartum hemorrhage has traditionally been treated with oxytocin, hormonal agents that induce muscle contraction. Studies have increasingly shown that oxytocin agents do not significantly reduce the incidence of post-partum bleeding or blood loss. Some studies have even shown that oxytocin agents are being overused, increasing the extent of risk of uterine dystonia.

If the uterine contractility agent is not functional, some mechanisms use the tamponade method as a two-wire treatment. These methods include Bakri uterine balloon tamponade, which works on the principle: insertion into the uterus and inflation presses the walls of the uterus outwardly, resulting in the filling of the bleeding blood vessels. The bleeding is controlled by pressing the blood vessel to generate stuffing, the operation time is long, the effect is poor, the expansion caused by the saccule can interfere the normal physiological uterine contraction and placenta bed vasoconstriction after delivery, and the myometrium can move back to a tension-losing state, so that the bleeding is caused again; and also fails to clean the blood clot tissue inside the uterus.

Therefore, how to effectively control postpartum uterine bleeding and clear blood clot tissue inside the uterus while maintaining physiological uterine contraction and placenta vascular contraction after delivery is a urgent problem to be solved by those skilled in the art.
