Description
本发明涉及医疗器械技术领域，尤其是一种多通道和多球囊的血管内快速止血球囊导管，其应用于创伤或战场时，发生在躯干或其他不可压迫止血部位的大出血的快速止血，或其他大出血情况发生时需保留生命器官的场景，其目的是在患者进入创伤中心进行影像引导手术控制出血之前，进行快速、临时性的控制内部出血，以保持重要器官的功能和维持中心血液循环。The invention relates to the technical field of medical devices, in particular to a multi-channel and multi-balloon intravascular rapid hemostasis balloon catheter, which is used for rapid hemostasis of major bleeding that occurs in the trunk or other incompressible hemostatic sites when applied to a wound or a battlefield, Or other scenes in which major organs need to be preserved when major bleeding occurs, the purpose is to quickly and temporarily control internal bleeding before the patient enters the trauma center for image-guided surgery to control bleeding, to maintain the function of important organs and maintain central blood circulation .
创伤性伤害是美国人在1到46岁之间死亡的主要原因。国家创伤研究所的报告和军方的联合报告指出，每年有超过25万人死于躯干不可压迫止血性出血(NCTH)、躯干血管、肺实质、固体腹部器官或骨盆腔破裂。Traumatic injuries are the leading cause of death among Americans between the ages of 1 and 46. The National Institute of Traumatology report and the joint military report indicate that more than 250,000 people die each year from incompressible hemostatic hemorrhage (NCTH) in the trunk, trunk blood vessels, lung parenchyma, solid abdominal organs or pelvic rupture.
临床上，临床上常用的止血带、加压包扎、夹持等方法，可用于临床上治疗肢体或表面躯干创面。可压迫止血伤口仅占与出血相关的战斗死亡的10％，与出血相关的平民死亡甚至更少。战场上的失血性死亡(越南战争中高达90％)主要是由于躯干血管出血造成的，这种出血无法直接施加压力，也无法通过这些传统方法加以控制。Clinically, methods such as tourniquets, compression bandaging, and clamping commonly used in clinical practice can be used to treat limbs or surface trunk wounds clinically. Compressible hemostatic wounds account for only 10% of fighting deaths related to bleeding, and even fewer civilian deaths related to bleeding. Hemorrhagic deaths on the battlefield (up to 90% in the Vietnam War) were mainly caused by bleeding from the trunk blood vessels, which could not be directly pressured or controlled by these traditional methods.
目前在NCTH的市场上没有商业产品被批准。在朝鲜战争中，创伤外科医生曾经尝试的方法是使用血管内球囊闭塞出血动脉(REBOA球囊导管)。目前REBOA球囊导管，在美国国防部1400万美元研发基金的支持下正在开展大规模的用于大血管出血快速止血的临床试验。该导管使用单一的闭塞球囊，不易被精准地部署到出血部位，且在止血的同时阻断生命器官的血液供应。No commercial products are currently approved in the NCTH market. In the Korean War, trauma surgeons tried to occlude bleeding arteries using an intravascular balloon (REBOA balloon catheter). At present, REBOA balloon catheters, with the support of the US Department of Defense's $ 14 million R & D fund, are conducting large-scale clinical trials for rapid hemostasis of large vessel bleeding. The catheter uses a single occlusion balloon, is not easily deployed to the bleeding site, and blocks blood supply to vital organs while stopping bleeding.
发明内容Summary of the invention
针对以上现有技术所存在的问题，本发明的目的是提供一种多通道和多球囊的血管内快速止血球囊导管。该发明中的球囊导管结构简单合理，可以不借助于透视技术定位到一个或多个躯干出血部位，并有效地放置以挽救生命，相对于REBOA单一球囊导管在创伤相关非压迫性出血的止血方面有了显著的改善。In view of the problems existing in the prior art, an object of the present invention is to provide a multi-channel and multi-balloon rapid hemostatic balloon catheter.
