Description
技术领域 technical field
本发明涉及医疗器械技术领域，尤其涉及一种产后止血系统。 The invention relates to the technical field of medical devices, in particular to a postpartum hemostatic system.
背景技术 Background technique
胎儿娩出后24小时内出血量超过500ml者称为产后出血，80%发生在产后2小时内。晚期产后出血是指分娩24小时以后，在产褥期内发生的子宫大量出血，多见于产后1-2周。产后出血是分娩期严重的并发症，是导致孕产妇死亡的四大原因之一。在我国产后出血近年来一直是引起孕产妇死亡的第一位原因，特别是在边远落后地区这一情况更加突出。产后出血的发病率占分娩总数的2%-3%，由于测量和收集出血量的主观因素较大，实际发病率更高。 Postpartum hemorrhage occurs when the amount of bleeding exceeds 500ml within 24 hours after delivery of the fetus, and 80% of the cases occur within 2 hours after delivery. Late postpartum hemorrhage refers to the massive uterine bleeding that occurs in the puerperium 24 hours after delivery, and is more common in 1-2 weeks 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%-3% of the total number of deliveries. Due to the subjective factors of measuring and collecting the amount of bleeding, the actual incidence is higher.
产后出血主要是因为宫缩乏力，造成胎盘剥离而出血，产后大出血严重者可直接导致产妇死亡，现有治疗办法主要是应用药物促进宫缩或子宫腔内填充纱布压迫止血，甚至需要进行子宫切除，应用填充纱布压迫止血，纱布的制作、填充比较困难，对宫腔内壁的压力也不均匀，容易形成死腔，导致止血失败。 Postpartum hemorrhage is mainly due to uterine atony, causing placental separation and hemorrhage. Severe postpartum hemorrhage can directly lead to maternal death. The existing treatment methods are mainly to use drugs to promote uterine contractions or fill the uterine cavity with gauze to stop bleeding, and even hysterectomy is required. , Apply filling gauze to stop bleeding, the production and filling of gauze are difficult, the pressure on the inner wall of the uterine cavity is uneven, and dead space is easy to form, resulting in hemostasis failure.
有鉴于此，有必要提出了一种产后止血系统以解决上述问题。 In view of this, it is necessary to propose a postpartum hemostatic system to solve the above problems.
