Full shielding type fixing device for dialysis tubes for arm internal fistula

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a full shielding type fixing device for dialysis tubes for arm internal fistula, the device comprises a protection assembly which is fit with the shape of an arm and made of cloth, a first limit mechanism and a second limit mechanism are arranged on the protection assembly, the first limit mechanism is used for limiting the movement direction of dialysis tubes, the second limit mechanism is used for limiting the dialysis tubes which are close to arteriovenous puncture needles to the protection assembly, the dialysis tubes are connected with the arteriovenous puncture needles after passing by the first limit mechanism and the second limit mechanism sequentially, the whole arm of a patient is wrapped with the protection assembly in a full shielding manner, the skin, exposed in the air, of the patient is reduced, the influences of the outside environment temperature and the backflow blood temperatureto the patient are reduced, at the same time, the dialysis tubes are limited on the protection assembly, so that the ranges where the dialysis tubes are fixed are larger, the limiting is stable, influences to the change of the puncture positions during arm moving are avoided, the hemodialysis process can be ensured to be conducted smoothly, and the pain to the patient body is also reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a fully-shielded dialysis tube fixing device for arm internal fistula. Background technique [0002] Hemodialysis is the process of draining blood from the body to the outside, removing metabolic waste and excess water in the blood through a dialyzer, and then returning the purified blood to the body. It is one of the renal replacement therapy methods for patients with acute and chronic renal failure. 1. At present, arteriovenous fistula is usually performed in the arm through surgery for hemodialysis. The artery near the wrist and the adjacent vein are sutured to form an autologous arteriovenous fistula or an artificial blood vessel is placed in the arm to connect adjacent veins. arteriovenous fistula is formed, and during hemodialysis, an arterial needle and a venous needle connected to the dialyzer through a dialysis tube are used to puncture the internal fistula to guide bloo...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is: for the current hemodialysis, the fixed area of ​​the tape to the dialysis tube is small, and the position of the dialysis tube is prone to be unstable, which affects the change of the puncture site, and the arm is exposed to the air, which is affected by the external environment temperature and the backflow of blood. The influence of temperature is large, which affects the smooth progress of the hemodialysis process, and brings physical pain and even life-threatening technical problems to patients. A fully-shielded dialysis tube fixation device for arm internal fistula is provided.
