Description

妇产科止血囊 Obstetrics and Gynecology Hemostatic bag

技术领域 FIELD

[0001]本发明属于医疗器械领域,具体涉及一种妇产科止血囊。 [0001] The present invention belongs to the field of medical devices, particularly to a balloon Gynecology hemostasis.

背景技术 Background technique

[0002]产后出血是产科最常见的并发症,宫缩乏力是产后出血最常见的原因,占70%。 [0002] postpartum hemorrhage is the most common obstetric complications, postpartum hemorrhage uterine inertia is the most common cause, accounting for 70%. 子宫肌纤维的解剖分布是内环、外纵、中交织。 Anatomical distribution uterine muscle fibers is an inner ring, an outer longitudinal interleaving. 正常情况下,胎儿娩出后,不同方向走行的子宫肌纤维收缩对肌束间的血管起到有效的压迫作用。 Under normal circumstances, the baby is delivered, the uterine muscle fibers contract in different directions of the running play an effective role of vascular compression between the muscle bundle. 如果出现子宫肌纤维收缩无力即宫缩乏力则失去对血管的有效压迫作用而发生产后出血。 If the uterine muscle fiber contraction postpartum hemorrhage uterine inertia that is unable to lose the effective compression effect on the blood vessels occurs. 胎盘因素占产后出血原因的20%左右。 Placental factors accounted for about 20% of the causes of postpartum hemorrhage. 根据胎盘剥离情况,胎盘滞留、胎盘粘连及部分胎盘和/或胎膜残留均可影响宫缩,造成产后出血。 The placental separation, the placenta, the placenta and the adhesion portion of the placenta and / or contraction may affect the residual membranes, resulting in postpartum hemorrhage.

[0003]子宫收缩乏力性出血,加强宫缩是最迅速有效的止血方法。 [0003] uterine bleeding, fatigue, strengthen contractions is the most rapid and effective methods to stop bleeding. 通常会滴注宫缩剂,当药物止血无效时,通常采用宫腔填塞纱条来止血,这是一种非常原始和简单的止血方法。 Contractions usually drip agent, when the drug is ineffective hemostasis, gauze usually uterine packing to stop the bleeding, it is a very simple primitive and hemostasis. 填塞过程耗时相当长,且对产妇的疼痛刺激重,在非麻醉状态下病人较难忍受,而且,如果经阴道填塞,无法避免纱条接触阴道壁而使无菌纱条被污染,使宫腔感染风险大大增加。 Packing process takes quite a long and painful stimuli of maternal weight, difficult to tolerate in the non-patient anesthesia, and, if the vaginal packing, the yarn can not be avoided contact with the walls of the vagina is sterile gauze pollution, house chamber greatly increases the risk of infection. 为了止血采用水囊来压迫子宫止血是较为有效的手段。 In order to stop bleeding using bladders uterine compression hemostasis is a more effective means. 现有的水囊容易漏水,不能持久全面压迫子宫,使子宫依然出血,而且产后宫颈松弛,宫腔内的水囊很容易滑出,导致压迫止血失败,鉴于上述原因,现有水囊不能在子宫止血中发挥很好的作用。 Existing bladders easy to leak, not a lasting and comprehensive oppression of the uterus, uterine still bleeding, and postpartum cervical relaxation, bladders intrauterine slide out easily, resulting in hemostasis failed, the reasons stated above, the existing bladders can not uterine hemostasis play a good role.
