Fixing device for hemodialysis internal jugular central venous catheter

Abstract

The invention provides a fixing device for a hemodialysis internal jugular central venous catheter. The fixing device is characterized in that neck fixing bands are arranged at an intersection (Y-shaped intersection) of a main catheter of the hemodialysis internal jugular central venous catheter and branch catheters at artery and vein ends, tail ends of two sides of each neck fixing bands can be fixedly combined with each other after encircling the neck of a human body by a circle, and a fixing sheet is further arranged at a catheter skin access in the main catheter according to different ranges of cathetering depths of the human body. The fixing device has the advantages that the hemodialysis internal jugular central venous catheter can be fixed to the neck skin access by the aid of the fixing sheet, the neck fixing bands are combined with the fixing sheet, accordingly, effects of fixing the hemodialysis internal jugular central venous catheter can be jointly realized, body suffering and psychological stress due to discharge and falling of suture lines and forced repeated suturing can be prevented, and problems of accidental falling of existing catheters due to repeated suturing, bleeding, infection, continuous expansion of wound at existing catheter skin inlets and tissue proliferation due to unstable fixing of the existing catheters and the like can be solved.

Description

technical field [0001] The present invention relates to an internal jugular central venous catheter for hemodialysis. Background technique [0002] In recent years, the prevalence of end-stage renal disease has been on the rise. Most of the patients need blood purification treatment, and the internal jugular central venous catheter is the most widely used temporary hemodialysis access in clinical practice, saving countless patients. patient's life. [0003] The existing fixing methods of central venous dialysis catheter are as follows: figure 1 As shown, after the main catheter body 1 is inserted into the patient's internal jugular vein, the suture wings 2 on the main catheter body 1 are sutured to the skin of the patient's neck with sutures to form fixation in turn, but this fixation method has shortcomings and deficiencies. [0004] First of all, the internal jugular central venous catheter is fixed with sutures on the suture wings. This fixing method cannot firmly fix t...

Problems solved by technology

[0008] In order to overcome the problem that the suture wings of the existing internal jugular central venous catheter for hemodialysis are not firmly fixed, and it is easy to spit out the suture many times and cause the suture to fall off, causing the central venous catheter to accidentally protrude, leading to the risk of bleeding and infection, and the risk of multiple sutures. Due to multiple scars on the neck and thus bringing huge psych
