技术领域technical field
本实用新型涉及医疗器械技术领域，具体是一种动静脉内瘘固定支架。The utility model relates to the technical field of medical devices, in particular to an arteriovenous fistula fixing bracket.
背景技术Background technique
透析疗法是利用半渗透膜来去除血液中的代谢废物和多余水分并维持酸碱平衡的一种治疗方法。透析疗法并不能治愈尿毒症或肾功能衰竭，它的作用是尽量以人工肾来取代已失去功能的肾脏，从而维系生命。血液透析中动静脉内瘘是常用的血管通路，是患者生命通道。动静脉内瘘的血管能为血液透析治疗提供充足血液，具有安全、血流量充分、感染机会少、易穿刺。但是目前在血液透析过程中将患者手臂放于床上，长时间的固定姿势，降低了患者的舒适度，如果固定不当，容易造成动静脉内瘘的渗血、血肿，或穿刺针脱出，需重新穿刺，增加患者的痛苦，同时在治疗前和治疗结束时，护士进行操作时长时间弯腰工作，造成护士慢性腰肌劳损，护士的职业满意度降低。Dialysis therapy is a treatment method that uses a semi-permeable membrane to remove metabolic waste and excess water in the blood and maintain acid-base balance. Dialysis therapy does not cure uremia or renal failure. Its role is to replace the lost kidney with an artificial kidney as much as possible, so as to maintain life. Arteriovenous fistula is a commonly used vascular access in hemodialysis, and it is the life channel of patients. The blood vessels of the arteriovenous fistula can provide sufficient blood for hemodialysis treatment, which is safe, has sufficient blood flow, less chance of infection, and is easy to puncture. However, at present, during the hemodialysis process, the patient's arm is placed on the bed, and the long-term fixed position reduces the comfort of the patient. If the fixation is not proper, it is easy to cause bleeding, hematoma, or prolapse of the puncture needle in the arteriovenous fistula. Puncture increases the suffering of patients. At the same time, before and at the end of treatment, nurses bend over for a long time to work, causing chronic lumbar muscle strain in nurses and reducing the professional satisfaction of nurses.
