Arteriovenous fistula marking, puncturing and fixing device

Abstract

The invention discloses an arteriovenous fistula marking, puncturing and fixing device. The device comprises a supporting plate, a placing groove, a spring, a clamping plate, a soft cushion, a guide plate and a placement box. The arteriovenous fistula marking, puncturing and fixing device is ingenious in structure, powerful in function and easy to operate. Firstly, the arm of a patient is fixed, so that the vein part of the patient is exposed to the outside to be fixed, then medical staff then use a B-ultrasonic machine to observe and evaluate shapes and lumen widths of arteriovenous vessels of the vein part of the patient and judge whether blood vessel branches and arteries are accompanied or not and whether available blood vessel lengths exist or not, and then puncture point marking is conducted on the inner side of the arm of the patient through a marking pen and a graduated scale, so that internal fistula puncture complications are effectively reduced, the pain of the patient is effectively reduced, and the dialysis quality is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an arteriovenous fistula marking puncture and a fixing device thereof. Background technique [0002] In clinical arteriovenous fistula puncture methods, there are three regional methods, rope ladder method, and buttonhole method. As the name implies, the local method is relatively fixed puncture area, which is easy to puncture. It requires low puncture level and high success rate in the early stage, but long-term puncture can easily lead to various puncture complications of internal fistula, reduce the service life of internal fistula and increase patient pain. . The rope ladder method is to puncture each puncture point (arterial point, venous point) equidistantly (0.5-1cm) in a step-by-step manner, and establish 3-5 puncture points for cyclic reciprocating puncture, which can reduce puncture complications and prolong the service life of the internal fistula. There are require...

AI Technical Summary

Problems solved by technology

For the three puncture methods, according to the (NKF-DOQI) international guidelines, in order to reduce the occurrence of access complications, the latter two puncture methods are advocated, but faced with the reality of undergraduates, the workload of nurses is heavy, the mobility is high, and young people account for 40% of undergraduates. And the level of puncture is uneven. Although all punctures are performed according to the requirements, the execution rate is low and the implementation cannot be fully carried out.
