Technical Field
[0001] The utility model relates to the technical field of medical auxiliary products, in particular to an arteriovenous fistula rope ladder puncture auxiliary positioning device. Background Art
[0002] An arteriovenous fistula, also known as an AVF, is a type of vascular access used for hemodialysis; it creates a direct arteriovenous channel by connecting an artery and vein in the arm to facilitate the removal of blood from the body during dialysis treatment, after which it is filtered and cleaned by the dialyzer and then returned to the body. The advantages of an AVF include a lower risk of infection, a lower risk of thrombosis, and a longer lifespan; compared to other types of vascular access, such as central venous catheters or grafts, AVFs can provide higher blood flow and more stable dialysis results.
[0003] After the completion of the arteriovenous fistula, the puncture position needs to be changed frequently during the later dialysis puncture to prevent frequent local punctures. However, in reality, since some positions are easier to puncture, nurses often puncture frequently in some easy-to-puncture areas, which eventually leads to regional punctures. There are many complications of regional punctures, such as local scars, vascular stenosis, pseudoaneurysm, thrombosis, bleeding, etc., and occasionally after a puncture fails, hematoma and skin cyanosis will occur, causing harm to the patient.
[0004] Therefore, how to design a puncture tool that can accurately indicate the puncture site, prompt the nurse to puncture evenly, and avoid regional puncture is a technical problem that has not yet been solved in the prior art. Utility Model Content
