Dialysis catheter fixing device for nephrology department dialysis

Abstract

The invention discloses a dialysis catheter fixing device for nephrology department dialysis. The device comprises a rotating sleeve, an outer sleeve and an extension spring, a rotating groove is formed in the rotating sleeve, the outer sleeve is installed in the rotating groove, an inner sleeve is slidably installed on the inner wall of the outer sleeve, semi-through grooves are formed in the outer walls of the two sides of the inner sleeve, and the extension spring is arranged in the semi-through grooves. A semi-through groove is formed in the top of the inner sleeve, an extension spring is installed on the inner wall of one side of the semi-through groove, a fixing ring is installed on the outer wall of the outer sleeve, a limiting ring is installed on the outer wall of the outer sleeve, a concave bottom frame is installed on the top of the inner sleeve, a concave top frame is installed on the top of the concave bottom frame, and multiple sets of threaded columns are installed on the top of the concave top frame. The dialysis tube can be doubly limited through the installed limiting ring and the arc-shaped soft plate, the pipeline is prevented from being twisted, the inner sleeve can move up and down in the outer sleeve to change the height of the whole device, the outer sleeve rotates in the rotating sleeve to change the corresponding direction of the dialysis tube, and the constant-temperature heating plate can heat the dialysis tube.

Description

technical field [0001] The invention relates to the technical field of nephrology, and belongs to a dialysis catheter fixing device for dialysis in the nephrology department. Background technique [0002] Hemodialysis is one of the renal replacement therapy methods for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. Inside and outside the hollow fiber, material exchange is carried out through the principles of dispersion, ultrafiltration, adsorption and convection to remove metabolic waste in the body, maintain electrolyte and acid-base balance, and remove excess water in the body at the same time, and return the purified blood. , in the dialysis process, the dialysis tube is used to circulate the blood in the body, and the dialysis tube needs a fixing device when transporting the blood, which can prevent the dialysis tube from swinging during dialy...
