器械由左房伞、右房伞、连接于外导管远端的贮囊、从远端穿出的内层右房导管以及内芯闭锁器金属丝组成。伞的材料为很薄的编织涤纶。金属部份用304不锈钢。右房伞连接于右房导管置于贮囊内,左房伞则连接在闭锁器金属丝上,亦置于贮囊内。贮囊的直径为5毫米,长15～20毫米。闭锁器金属丝直径为1.1毫米。整个导管系统全长100厘米。伞张开后的直径为1～4厘米,重量小于500毫克。安置操作:先作心导管检查确定房间隔缺损的存在,并测定缺损直径,以选择伞的合适尺寸。然后,用肝素(100单位/公斤)抗凝。将导管经股静脉插
The instrument consists of left atrial umbrella, right atrium umbrella, a reservoir connected to the distal end of the outer catheter, an inner right atrium catheter expelled from the distal end, and an inner core stopper wire. Umbrella material is very thin woven polyester. 304 stainless steel metal parts. Right atrial umbrella connected to the right atrium catheter placed in the storage bag, the left atrial umbrella is connected to the stopper wire, also placed in the storage bag. The diameter of the bladder is 5 mm and 15 to 20 mm long. The diameter of the stopper wire is 1.1 mm. The entire catheter system length of 100 cm. Umbrella open diameter of 1 to 4 cm, weighing less than 500 mg. Placement Operations: Cardiac catheterization was performed to determine the presence of atrial septal defects and the defect diameter was measured to select the appropriate size for the umbrella. Then, anticoagulation with heparin (100 units / kg). The catheter is inserted through the femoral vein
