Description
技术领域technical field
本实用新型属于医用装置领域，特别涉及一种用于血透病人的带气囊的长期血透导管。The utility model belongs to the field of medical devices, in particular to a long-term hemodialysis catheter with a balloon for hemodialysis patients.
背景技术Background technique
血液净化治疗主要用于肾功能衰竭的肾替代治疗主要治疗手段之一。长期血透导管置入给予动静脉内瘘成熟充分的时间，同时对于没有动静脉内瘘手术条件的患者建立生命线。长期血透导管置入过程尤其是在皮下隧道建立过程中出现小血管损伤或皮下软组织挫伤导致的导管口渗血，严重渗血不止可能需要拔除血管通路，反复渗血亦可能导致皮下隧道感染。肾衰竭患者贫血发生率高，长时间渗血容易导致贫血加重、导管口感染，快速有效的止血对控制失血，避免感染有重要意义。血透间隙血液进入导管容易导致血栓形成，导管流量不佳减少导管使用年限。同时导管发生感染时，将导管封闭可保证导管内封管的药物浓度，同时阻挡导管内的细菌进一步释放入血，避免菌血症的发生。避免血液在透析间隙进入导管可有效减少导管内血栓的形成、感染进一步的扩散。Blood purification is one of the main treatments for renal replacement therapy for renal failure. Long-term hemodialysis catheter placement allows adequate time for the arteriovenous fistula to mature and establishes a lifeline for patients without surgical conditions for the arteriovenous fistula. In the process of long-term hemodialysis catheter placement, especially during the establishment of the subcutaneous tunnel, small blood vessel damage or subcutaneous soft tissue contusion may cause bleeding at the catheter port. Severe bleeding may require removal of the vascular access, and repeated bleeding may also lead to infection of the subcutaneous tunnel. The incidence of anemia in patients with renal failure is high. Prolonged oozing of blood can easily lead to aggravation of anemia and infection of the catheter orifice. Rapid and effective hemostasis is of great significance to control blood loss and avoid infection. Blood entering the catheter during the hemodialysis interval is likely to cause thrombosis, and poor catheter flow reduces the service life of the catheter. At the same time, when the catheter is infected, sealing the catheter can ensure the drug concentration in the catheter, and at the same time prevent the bacteria in the catheter from being further released into the blood, so as to avoid the occurrence of bacteremia. Preventing blood from entering the catheter during the dialysis interval can effectively reduce the formation of thrombosis in the catheter and the further spread of infection.
目前临床中使用纱布、绷带进行导管皮下隧道周围皮肤组织压迫止血，或加缝数针，但止血效果差，且常常影响透析导管的流量。导管预充抗凝药物、抗生素后，但仍可见血液进入导管内。At present, gauze and bandage are used in clinic to compress the skin tissue around the subcutaneous tunnel of the catheter to stop bleeding, or add a few stitches, but the hemostasis effect is poor, and the flow of the dialysis catheter is often affected. After the catheter was prefilled with anticoagulants and antibiotics, blood was still seen entering the catheter.
