Description

Special clamp for long-term catheter of hemodialysis center vein

Technical Field

The utility model relates to a hemodialysis technical field specifically is a special clamp of long-term pipe of hemodialysis central vein.

Background

Many hemodialysis patients use a central venous long-term catheter which is buried in the body, the catheter can be left on the patients for as long as a year or even longer, which puts strict requirements on the ordinary nursing and sensory control of the catheter, the catheter needs to be disinfected frequently, and plastic clamps on the catheter can be broken off in the long term. It is not cost effective to replace the entire catheter if the option is to break the clip, because a catheter costs several thousand dollars, which can increase patient burden. Other clips are found for clinical use in the past, but the situation that the size and the specification are not matched inevitably occurs, and the clip is inconvenient to wrap on a patient.

The former clamping that has now can break through long-term use and disinfection, and because this one end that the pipe exposes is than thick in the time of the change, the same clip cover of size can not go into, and the size does not match, and the locking clamp is difficult for the installation when the replacement, changes and produces the bacterium easily, is difficult to satisfy the special demand that presss from both sides of long-term pipe of hemodialysis central vein now.
