Description
技术领域technical field
本发明属于医疗设备领域，特别涉及一种用于回复PICC静脉折返异位以及输液港异位的笔式静脉阻断仪。The invention belongs to the field of medical equipment, and in particular relates to a pen-type venous occlusion instrument for restoring PICC venous reentrant ectopia and infusion port ectopia.
背景技术Background technique
经外周静脉置入中心静脉导管(peripherally inserted central catheter，PICC)：经外周静脉(如：贵要静脉、肘正中静脉、头静脉等)置入中心静脉导管，导管尖端位于上腔静脉下1/3与右心房连接处，即右心耳处。适用于中长期静脉输液、肿瘤化疗、肠外营养、老年患者输液。20世纪90年代开始美国就将B超引导结合塞丁格技术引入PICC置管中，目前临床上多使用该技术进行置管。但置管过程中由于解剖变异或患者体位配合不到位以及操作手法等原因，往往会导致PICC头端异位。导管异位是PICC置管最常见的并发症，文献报道其导管尖端异位率可高达34.2％。导管异位会增加液体渗漏，导致局部肢体肿胀、静脉炎、导管堵塞、静脉血栓、疼痛等并发症的发生，还可导致不能完成治疗而废弃导管，有时需要重新置管。Peripherally inserted central catheter (PICC): a central catheter is inserted through a peripheral vein (such as basilic vein, median cubital vein, cephalic vein, etc.), and the tip of the catheter is located in the inferior 1/2 of the superior vena cava 3 The junction with the right atrium, that is, the right atrial appendage. It is suitable for medium and long-term intravenous infusion, tumor chemotherapy, parenteral nutrition, and infusion for elderly patients. Since the 1990s, the United States has introduced B-ultrasound guidance combined with Seidinger technology into PICC catheterization. At present, this technology is mostly used in clinical practice. However, due to anatomical variation, poor coordination of the patient's body position, and operation techniques during the catheterization process, the head of the PICC will often be misplaced. Catheter misplacement is the most common complication of PICC catheterization, and the rate of catheter tip misplacement can be as high as 34.2%. Ectopic catheter will increase fluid leakage, leading to complications such as local limb swelling, phlebitis, catheter blockage, venous thrombosis, pain, etc.
PICC导管异位以异位于颈内静脉最常见。由于头静脉穿刺，体位未摆好，置管太浅(如到头静脉或上腔静脉的上段经体位的改变、头低脚高位、用力咳嗽可异位头静脉)原因致导管入颈内静脉。PICC是盲穿，个体血管千变万化，出现导管异位不可避免。出现导管异位后如何处理成为关键。现在一般对于颈内静脉异位，如进入长度不深，多让患者做跳跃动作或者从上到下走楼梯，通过重力原理使导管回至无名静脉；如果进入长度深时采用拉出导管到肩部位置用边冲边送导管的方法。Ectopic PICC catheters are most commonly located in the internal jugular vein. Due to the cephalic vein puncture, the body position is not properly arranged, and the catheter is too shallow (such as the upper part of the cephalic vein or the superior vena cava, the body position changes, the head is lowered and the feet are raised, and the cephalic vein can be misplaced by coughing hard). The catheter enters the internal jugular vein. PICC is blind puncture, individual blood vessels are ever-changing, and catheter ectopia is inevitable. How to deal with catheter abnormality becomes the key. Now generally for internal jugular vein ectopia, if the entry length is not deep, let the patient do jumping movements or walk up and down the stairs, and return the catheter to the innominate vein through the principle of gravity; if the entry length is deep, pull out the catheter to the shoulder Use the method of feeding the catheter while punching at the external position.
完全静脉植入式输液港(totally implantable venous access ports，TIVP)是一种完全植入皮下、可供长时间留置体内的静脉装置，适用于需要长期反复静脉穿刺、化疗、肠外营养支持以及输血的患者。目前，临床常用的植入入路为经锁骨下静脉的胸壁输液港和经外周血管如手臂贵要静脉、肱静脉和正中静脉植入的手臂输液港，也会存在颈部和腋下异位的情况。Totally implantable venous access ports (TIVP) is a venous device that is completely implanted under the skin and can be left in the body for a long time. It is suitable for patients who need long-term repeated venipuncture, chemotherapy, parenteral nutrition support and blood transfusion. of patients. At present, the commonly used clinical implantation routes are the chest wall infusion port through the subclavian vein and the arm infusion port implanted through peripheral blood vessels such as the basilic vein, brachial vein, and median vein of the arm, and cervical and axillary heterotopias also exist. Case.
