Description

Blood seepage prevention and subcutaneous pressure reduction device for arteriovenous fistula puncture Technical Field The invention relates to the technical field of vascular access management auxiliary devices, in particular to a blood seepage prevention and subcutaneous decompression device for arteriovenous fistula puncture. Background An arteriovenous internal fistula is a vascular access for a hemodialysis patient to maintain life, and when a puncture needle is pulled out after treatment is finished, effective compression hemostasis and subcutaneous protection of the puncture point are important for prolonging the service life of the internal fistula. At present, compression hemostasis after clinical needle withdrawal mainly depends on manual pressing, elastic tourniquet or adhesive tape fixing compression pad, but in practical application, the traditional modes have obvious limitations, and the increasingly-improved clinical puncture protection requirements cannot be met. Firstly, most of the prior tourniquet or adhesive tape is fixed by hard compression, the applied pressure is difficult to quantify and lacks a stable maintenance mechanism, the long-term excessive compression not only can cause pain of patients, but also can easily induce internal fistula thrombosis, and if the strength is insufficient, subcutaneous bleeding or hematoma formation can be easily caused. In addition, the existing tool lacks a mechanical energy release and instant pressure reduction structure, so that medical staff acts slowly and has drag when releasing pressure, the formed blood clot is extremely easy to damage, friction and traction are caused on local skin and blood vessels, and secondary tearing and blood seepage of a puncture point are caused. Secondly, most existing compression devices only focus on a single compression point, and lack auxiliary fixing and limiting of an external dialysis pipeline and a flexible buffer structure of the whole device. In the dialysis process or in the initial stage of needle pulling and pressing, the slight movement of the arm of a patient or the suspension dead weight of a pipeline can continuously and mechanically pull the puncture part, so that the device is very easy to loosen or shift when being stressed, and the clinical risks of needle shifting and blood leakage are greatly increased. Therefore, the prior art is difficult to simultaneously meet multiple clinical requirements of accurate pressure control and maintaining, rapid and thorough pressure reduction and pipeline involvement prevention. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a blood seepage prevention and subcutaneous decompression device for arteriovenous fistula puncture, which solves the problems that the internal fistula is damaged, secondary blood seepage is easily caused by slow decompression and the puncture needle is easily shifted and leaked due to the involvement of the effective fixation of a dialysis pipeline because the compression force is difficult to accurately regulate and stably lock in the traditional compression hemostasis mode.
